Historical Meme:Things about Stephen Gray

























Stefan Scherer of Backreation has tagged me with one of those blog memes - in this case, a variant of the Historical Meme. The idea is to:

Actually, as like Stefan, I’m a bit of a science history buff. This does present a problem, since in being so it is difficult to choose one out of the many people I have come to admire. However, what came to the rescue in my quandary was the recent unfortunate episode that took place resultant of comments made in a entry that was posted on Backreaction just before I was tagged. This brought to mind a scientific figure in history who defines as a hero for me not simply because he added to the book of understanding of nature, yet more importantly that he did this despite what would be for many seemingly insurmountable obstacles. The person I have thus chosen is as noted Stephen Gray.




“The electric fire which by several of these experiments seems to be of the same nature with that of thunder and lightening.”

Today it is agreed by many, that he should be regarded as the father of electrical communications and therefore not Morse, Marconi or Bell, which instead were the benefactors’ of his contributions. That is he was the first to conduct experiments that would be after understood and later refined to lead to the realization of both its methods and potential. Ironically the reason he wasn’t is not resultant of his humble beginnings or station, nor certainly of lacking of commitment or ability, yet mainly the tyranny of the most noted person in modern science. He thus stands and serves as a lesson from which all his peers after should take note of and consider.

It should not be thought that I have written this to villanize and thus lessen your respect for Newton. It was done rather to perhaps have you now come to respect and admire one who truly deserves to be.

The information in this post was primarily sourced from the book entitled “Newton’s Tyranny (The Suppressed Scientific Discoveries of Stephen Gray and John Flamsteed)” written by David H. Clark and Stephen P.H. Clark-W.H. Freeman and Company-2000. Also in relation to the quanity of things I noted you will discover I can't count:-)

Does Humanity relate to the Why?







As I have pointed out in my other blog, is that as of late I have come across a wonderful web site that is created and hosted by two (married to each other) physicists. What is interesting about this site is that one is not just simply exposed to the thoughts, convictions and beliefs of a few physicists, yet rather they have provided a structured forum in which to discuss science in general and how it relates to and is perceived by the world. This site not only includes like-minded people as themselves yet rather a broader spectrum of those I consider myself a part of, which I refer to as the wonderers.

What is to be found in the following, is a comment I left on this site in relation to a subject that started out as a discussion of a book called the “The Ingenuity Gap” and evolved into a discussion of what our society is, what are its problems, why they are so, and most importantly how they might be solved. Subsequently there was a lot of discussion about what the responsibility, role, and place an individual serves to be in all of this. The main point of contention and query was to question whether society and its instrument, government, primary purpose is to serve the people as individuals or are the individuals there to serve the purpose of society. My contention was that it is neither in as both viewpoints are correct and yet incorrect. What is found hereafter is exactly as it is on the site with one exception, which is the last paragraph. This I excluded because the site is dedicated first and foremost to the scientific format (philosophic viewpoint) and thus I omitted it there out of respect for the creators and their intentions.

Hi Bee,

Though I am very sympathetic to this, and it might indeed be the way to go, it is just not true……….You can go a big step further by changing the political system itself, for neither of these examples you need a bottom-up approach, all you need is to convince the top (I am very much a bottom-up person though).

The way I see society there is no bottom up or a top down to consider. That is because it only amounts to a whole as to the function that is common. You could equate this to an organism as opposed to a single cell. In an organism we have different cells for different functions. They all must function properly or the whole organism suffers. Yet this is a strange organism, for unlike a typical one where the parts are in service of the whole, the organism of society is one that exists in the service of its parts. So in contrast to the typical organism, where it is a common (and required) strategy to sacrifice individual cells to maintain the whole; in the case of the social organism this is not seen as the right thing to do. This of course is the dilemma. As an example, in the contemporary context wars are seen as wrong, not so much because they have no chance to benefit the organism, yet rather because they sacrifice the parts (cells). This on its own is why a society is required to be moral rather then a typical organism where such a practice would be considered not only wrong yet ultimately destructive.

It is often proclaimed by many, that the reason for our current plight is that we defy nature and if we were simply to obey her we would have no problems; and yet as I have indicated, the whole modern concept held by these same people, as I have shown, is by its very nature required to run counter to the claim. I would ask then what is it to be? Should society be perceived as an organism where the parts are necessarily sacrificed for the good of the whole or must it act for the good of each part at the sacrifice of none? If it is the former we have always had what’s required, if it’s the latter we then stand in defiance of nature. Therefore, it must be first understood that morality is not natural (as commonly perceived) and if we want to hold our ideals we must not only understand this to be true, yet further are required to stand together in this defiance.

Regards,

Phil

What I didn’t say on the site is as follows:

So then, am I proposing that society’s ulitmate goal is unnatural and perhaps then wrong? No, for this is a misunderstanding resultant of restricting oneself to two dimensional and/or flawed logic. That is to consider when something that is not like the other, it then must be the opposite. When you incorporate three dimensional logic; that is when something in one sense is similar and yet exceeds in some aspect what it’s being compared to, it is not the opposite or negative, yet rather the superior or evolved state. The superior or evolved state of natural is then supernatural, not unnatural. It has been speculated by some (myself included) that all life in general is the first stage of this departure to become superior to nature. What mankind’s goal as many have envisioned would thus be the completion of this. The question of course is, do we (humanity) have both the conviction and capacity to complete the program or are we simply another step in the evolution of life to end in this completion? I don't profess to know, just merely wish to offer another avenue of thought one might explore and also to suggest reason to consider that not only the how and the what as relevant to understanding, yet also the why.

Time, is it an Essence?









As you may recall in a previous entry I discussed time and how it could and is considered in physical terms. That is where time is not simply imagined as a marker which we use to separate one state in a changing physical process from another, yet rather as an actual part of the physical process itself. That is as to be a dimension or degree of freedom which forms part of the actual substance of reality to both define the limits of the scope and potential to which such physical process can evolve. Now what is interesting and relevant in the context of this blog is this has been and still continues to be a central subject of study and concern for both of our considered two disciplines, being science and philosophy. In this way it forms a commonality within the struggle for understanding shared by both.

To continue, in order to explore this further, I wondered how I might form an analogy that could at least, in some crude way, describe what I’m talking about as to whether time is simply a marker within physical process or rather is part of the physicality of the process itself? The analogy I have come up with is to be found in the comparison of playing a record (musical phonograph) with the actual production of one. So to begin when we play a record what is involved? What’s entailed is that first we have a media (substance), on which there is inscribed a pattern (information), that when actualized by a process (the playing) we are presented with or realize its content. This physical process of course involves motion in the sense that the record turns (travels) and a needle striking (following) dimensional differences within the media presented. These differences scientifically would be described in terms of its amplitude (height), wave length (length) and frequency (depth or density or how many per given length). These could be considered as the three commonly understood dimensions (degrees of freedom) of what we understand as space and can be interpreted and imagined without the need for anything else at all. That is they can remain fixed and still be thought to be real. However to have all this actualized or realized for the listener we must have something else and that is the movement (time) which when added has the music come into being. This compares to how some physicists imagine time to be as a dimension.

First, it is important to point out that the three (space) dimensions between them can have no affect on each other or enable there actualization (to be realized as considered fixed. However. the fourth one (time) certainly can. What do I mean by this? Well let’s consider the record again. In the playing of a record to have it come out (realized) the way it was recorded it must turn at a speed that is consistent with the way it was produced and the record must turn in the correct direction (clockwise or forward as formed). To play it at a different speed, although one may still be able to comprehend it, will have it display different qualities (characteristics) as related to the perceived (not self actual) distances of all three involved. To play it in the opposite direction renders it for the most part incomprehensible. I think you can see what I’m getting at here. That is in Einstein’s view of reality all what I have said comes into consideration. The speed (time) of the universe can have us perceive and experience our reality (the universe) differently according to the speed and relative to the fixed qualities and quantities of its content (mass/energy). Also, it suggests that if this is to be meaningful at all, it can have only one direction. This is considered in science within an action or consequence of action called entropy, where the averaged actual relative positions of the matter/energy contained in the universe is perceived as becoming more disordered as related to both its previous and initial state. This in turn is connected to space to both expanding and lowering in average energy content (temperature).

Now this is where the two concepts in a way cross swords. In the entropy concept time is simply a marker, in as it is only considered as way to differentiate one state of realization from the other and therefore is merely a tool used in our conceptualization of it. This is however only true if you consider this speed as being both constant and regular. In other words if time has only one aspect (character or element) and thereby consequence. Yet how could this be other then having something external arbitrarily controlling these variables. This would seem to point to some omnipotent being or some such thing being required. What we forgot is that in our analogy of the record the difference between playing one and making (producing) one. When we play a record we only actualize what has already been produced. When a record is being made it is in the act of forming what it is to be. In the case of the recording a record someone supplies the content (music) and the pattern (information) of this is etched (copied) to a malleable and consistant physical substance such as wax. So is this the only way to make a record that would realize something and thus require conscious and intended input? There is another way this could be considered and that is the medium on which it is being recorded although holistic (one thing) is not homogenous or predicatively consistent. Imagine something like a wax plate that had itself both varying malleability and slickness (resistance to travel). What would be produced if we cut a record on such a substance without supplying input? What would happen is that the needle when confined to the inward revolving motion facilitated with a constant force of rotation (travel) would create grooves displaying varying amplitude(height), wave length(length) and frequency (depth or density) in accordance to these related factors. That is that the record produced would create a pattern (information) that tells one of the character of the substance encountered in relation to the action included (time). In this way the whole thing is resultant of the mutual potential realized (actualized) between the two.

So now let’s speculate further how this could relate to our world as what it serves to represent. First it should be understood that the playing of the record is not a state of being or becoming but merely the act of observing the past. This we also do every day when we look out in front of us whether it is merely at the screen of this computer I am typing on or out into the heavens at night. It is only different in terms of how far this is from our own now (present). The being of the universe takes place in the now (cutting the record) which is never truly experienced only later to be realized. The becoming is in the future and depends on what is encountered (nature of the wax). It must be understood that within this highly speculative model although the character or nature of the substance on which it will be enacted (realized) is already there and in some sense predetermined. However in the act of travelling through, although the force and initial direction may be set and consistant, would however still leave this future to remain difficult if not impossible to predict. What would make this truly to remain uncertain and unknowable is of course is if the substance itself is not simply variable because of a changing set nature but rather if it were also reactant to itself and by its own complex interactions constantly changing in terms of its total local and universal character at any given instance. This universal character although changing could still preserve its overall (averaged) value.

All this of course supplies no answers and yet at least gives us one way to frame the questions of concern which are how, what and why. This may give you further reason to understand and perhaps even to accept that we can and should address them all as to be considered in terms of our search for understanding.

“Time present and time past
Are both perhaps present in time future,
And time future contained in time past.
If all time is eternally present
All time is unredeemable”

How vs. Why, the Confusion Continues





There have occurred two recent events which served for me as a reminder that the central contention of this blog is certainly relevant. Those two events being first, the publication of Richard Dawkins’ new book entitled “The God Delusion followed with the announcement of Answers in Genesis, a Christian ministry that are launching a (contended to be) scientific journal called “Answers Research Journal” (reported in Nature)that will be accessible online. These two certainly exemplify what I see as the true problem in regards to humanity's search in the understanding of our world. Also, it serves to further demonstrate how our two central philosophies, one which are called religions and the other science have come to being even more strongly diametrically opposed.

In attempting to explain what I mean, first I’d like to expand a little on who Richard Dawkins is and what he reports to represent. Dawkins’ is an ethologist, evolutionary biologist and popular science writer out of England. He currently serves as the Charles Simonyi Chairman (Oxford’s) for the Public Understanding of Science. He first came to public attention in the writing of the book “The Selfish Gene” in 1976 (which I’ve read). This book’s central contention is that evolution is executed primarily from (and for) the single cells perspective, rather then the organisms’ as a whole. In Dawkins’ view the organism is simply the extended machinery though which all this is manifested and observed with genes being the expeditor of this process. This is one possible logical extension of Darwin’s theory and it is not my intention to contest it. What issue I have with Dawkins is his new books primary intent and focus is to take it upon himself to become the self appointed representative/champion of science to insist that his theory and connected others amount to a proof that there is no “why” to the world. His limited understanding of this is of course is that there is no God.

Now on the other side of the coin we have this Christian Ministry headed by Ken Ham which is a propagator of the creationist (Intelligent Design) view. He headed up the effort to fund and execute the building of what’s called the Creation Museum whose claimed sole purpose is to educate people of the validity of holding such a position. Now what has been just recently started by the same group is what is reported to be a Scientific journal called “The Answers Research Journal” which is to represent what they contend will be a traditional, peer reviewed scientific research publication. The peer review however will be carried out by only scientists that are supportive and sympathetic to this concept.

What I find most revealing (and disconcerting) in all this is the polarity that is clearly demonstrated when you consider the attitude of many scientists when compared with those of many religious philosophies. They both somehow misunderstand and misrepresent their indepenantly decided and defined limited roles in terms of the search for understanding. First as I have explained in the past the separation of the roles is defined as such. First for modern (homocentric) philosophy as previously defined as the following:

“Investigation of the nature, causes, or principles of reality, knowledge, or values, based on logical reasoning rather than empirical methods“.


Now I remind here the role served by science and it’s methodology as defined by Newton which is:

“In this philosophy particular propositions are inferred from the phenomena, and afterwards rendered general by induction.”


So then, what this time is my point? First it must be realized that those of Dawkins stripe are now stepping outside of their philosophical mandate to say that it is science’s responsibility to prove and insist that not just creationist religions,yet rather all religions are false and should be dismissed as not only just being wrong yet also being dangerous. Then we have many religious philosophies that contend that they not only know the “why” yet many of the details and can prove it and thus science must be dismissed in this regard. What this demonstrates to me is that those scientists such as Dawkins thus claim in effect that they (I paraphrase)” believe or have faith in science” while religious figures such a Ken Ham claim in effect (I paraphrase)” they have proof for the existence and intent of God”. I will thus simply point out that both statements in terms of their central methodologies are oxymorons.


In conclusion today, I would like to once again remind that this need not remain to be a problem. For it has been demonstrated by people such a Plato, Descartes, Darwin and Einstein who found it possible to find the “how” and the “what” of the world while remaining convinced and assured that we will ultimately discover the “why”.

What truly is Einstein’s Moon?






As you recall in my last post I was speaking as to why Albert Einstein served as my inspiration in coming to realize that science should not be content to restrict itself to only answer “how” the world works but also to imagine “what” it is and “why”. In doing so I attempted to demonstrate Einstein’s thoughts on what science should explore and serve to be. I offered you the insight that Einstein’s strength in his pursuit of understanding and discovery rested on the fact that he were not just simply intelligent: but, that also he was a man of conviction as to what should be considered to represent truth in our world. More specifically I said I would attempt to explain what significance this blog’s question “What is Einstein’s Moon” is in reference to.

To begin, despite all the success and favor Einstein attained in life; he, until the end of his days found himself to be an outsider in the then forefront of scientific discovery. That forefront of course was with the dawn of quantum theory, which attempts to explain our world at the very small (non perceived) scale. Today some believe that this was due to Einstein not understanding the subject or perhaps even compounded by advancing age. Nothing could be further from the truth. In fact he was one that laid the foundations for its beginnings. For instance it is widely assumed that Einstein was awarded the Noble prize for his work on special and general relativity. This is not so. What he was given the Nobel Prize for was in showing that if light was considered as a particle it could explain why only light above a certain frequency (energy density) could free electrons from specific materials. We exploit this today in many applications, most notably the solar cell. This along with Max Planck’s ideas marked the birth of what is considered modern atomic physics. In continuance with this, he inspired, communicated and consulted with all those who became known as the founders of quantum theory. So then, how did Einstein find himself outside the consensus formed about the nature of the quanta that emerged and for the most part is still accepted in the main today?

How Einstein came to find himself in this position was two fold, in that quantum theory implied two things about nature with which he had trouble with. First, the theory proposed things about the world that appeared inconsistent with his own theories, specifically special relativity. Second, the theory dismissed the objective nature of the world. That is it suggested that the world of which we are aware is somehow connected with ones perception of it and in some respect is not real in the normal sense of meaning until it is so perceived. This if taken to the extreme could suggest that every individual (not just person but rather organism) has its own private reality. As time progressed Einstein was to focus his attention primarily on this second feature as to be its central flaw. He can be seen in the act of expressing this doubt about what the new theory implies and what the responsibilities of scientists are when he writes a paper entitled “Physics and Reality” for the journal of the Franklin Institute [Volume.221, No. 3, March 3, 1936], he states in the opening paragraph the following:

“It has been often said, and certainly not without justification, that the man of science is a poor philosopher. Why, then, should it not be the right thing for the physicist to let the philosopher to the philosophizing? Such might indeed be the right thing at a time when the physicist believes he has at his disposal a rigid system of fundamental concepts and fundamental laws which are also well established that waves of doubt cannot reach them; but, it cannot be right at a time when the very foundations of physics itself become problematic as they are now. At a time like the present, when experience forces us to seek a newer and more solid foundation, the physicist cannot simply surrender to the philosopher the critical contemplation of the theoretical foundations; for, he himself knows best, and feels more surely where the shoe pinches. In looking for a new foundation he must make clear in his own mind just how far such concepts which he uses are justified, and are necessities.”

Now to indicate that the physicists truly thought as Einstein perceived I offer here a quote of Aage Petersen paraphrasing Niels Bohr (a founding father of quantum theory):

“There is no quantum world. There is only an abstract physical description. It is wrong to think that the task of physics is to find out how nature is. Physics concerns what we can say about nature.”

So as can be seen not only can we assume that Bohr dismisses the “what” and “why” of the world, which in some ways we have come to expect of science; he, says we can no longer be permitted to ask “how” and should be content with what we can say about nature, which serves to answer essentially nothing at all. Einstein was thus considered unreasonable in not accepting this.

As part of this distaste for not looking for a objective description of the world Einstein was not content with the fact that nature’s actions were not just merely perceived to be so complex that they could only be predicted within a statistical framework, but, rather that there was no framework at all and that the statistics where due to the fact that nature at the base level acts randomly. This is even furthered in quantum mechanics to suggest that cause is not related to effect. That is to say that nature has no reason at all. Einstein can be seen here complaining about this in a letter he wrote to a friend and fellow physicist, Max Born, on September 7, 1944[Born-Einstein Letters], when he says to Born:

“We have become Antipodean in our scientific expectations. You believe in the God that plays dice, and I in complete law and order in a world which objectively exists, and which I, in a wildly speculative way, am trying to capture. I firmly believe, but I hope that someone will discover, a more realistic way, or rather a more tangible basis than it has been my lot to find. Even the great initial success of quantum theory does not make me believe in the fundamental dice-game, although I am well aware that our younger colleagues interpret this as a consequence of senility. No doubt the day will come when we will see whose instinctive attitude was the correct one.”

As indicated above then Einstein’s main objection to quantum mechanics, as it was accepted, was that it lent no reasonable explanation of the world and in some sense denied what many would perceive as what it means to truly exist. As a further testament to this once while walking with physicist and his biographer, Abraham Pais, Pais reports in frustration Einstein asked whether I really believed that the moon exists only when I look at it."

To conclude, I hope that you more clearly understand why I chose Einstein to represent both the inspiration and purpose of this blog. That is, with him, I am convinced that mankind should have hope that we will not only continue to explore and discover “how” and “what the world truly is, yet further to be confident that we will ultimately come to realize “why”.

As a postscript to this I'd like to leave you with what Einstein said in relation to all this in the conclusion of a paper he called “The Fundamentals of Theoretical Physics” in the journal [Science- May 24, 1940]

“Some physicists, among them myself, cannot believe that we must abandon, actually and forever, the idea of direct representation of physical reality in time and space; or that we must accept the view that events in nature are analogous to a game of chance. It is open to every man to choose the direction of his striving: and also every man may draw from Lessing’s fine saying, that the search for truth is more precious than its possession. “

Why “Einstein’s” Moon?




To the few readers of this blog you may have been curious as to how (for me) a blog that is concerned with the “how”, “what” and “why” holds any relevance to Albert Einstein. Also, you may be interested as to why Einstein’s Moon in particular is significant in terms of this blog’s subject matter and focus. First, I must admit that if there is a person in history that has influenced me more then Plato it is Einstein. In fact I started this whole journey of the discovery and contemplation of scientific and philosophic consideration primarily due to his influence. However, to my recollection as to how the whole thing began is that in 1957, as a very young boy, I heard the eerie beeping’s of the first man made satellite over a radio. This of course was the Soviet’s “Sputnik” meaning “fellow traveler”. So you might say that it all started with the practical beginnings of the space age. This event instilled in me a curiosity about science and the nature of the world that has continued to this day. Initially I was primarily interested in modern science and the person that represented this most poignantly was of course Albert Einstein. He did then, and I would say still today, personifies the best of wisdom and science's abilities that the modern age has acheived. Realizing this I proceeded to gather and study everything I could, not only about his science, but also the man and his thoughts.

So enough about me, let’s speak of Einstein as he relates here. What I discovered about Einstein was two fold. That was that his discoveries where made not only because he was intelligent but also because he held a conviction about how the world works and what it should be. This conviction gave him the confidence and tenacity to follow up on ideas he saw as viable, even if they were not considered consistent with the main stream or popular view within his discipline and more importantly his time. This begs the question, how did he get this way? Well besides the blessings of what he was born with and what his parents nurture instilled in him, it was a consequence of what else influenced him in his development. That influence was found in part as result of his education, however I would say more importantly it is found in what he read and studied beyond the curriculum. I could go on for some time as to what this entailed but Einstein has already said this for himself when he was commenting as to what he viewed as the misguided direction of much of contemporary thought when in 1952 he said:

“Somebody who only reads newspapers and at best books of contemporary authors looks to me like an extremely near-sighted person who scorns eyeglasses. He is completely dependent on the prejudices and fashions of his times, since he never gets to see or hear anything else. And what a person thinks on his own without being stimulated by the thoughts and experiences of other people is even in the best case rather paltry and monotonous. There are only a few enlightened people with a lucid mind and style and with good taste within a century. What has been preserved of their work belongs among the most precious possessions of mankind. We owe it to a few writers of antiquity (Plato, Aristotle, etc.) that the people in the Middle Ages could slowly extricate themselves from the superstitions and ignorance that had darkened life for more than half a millennium. Nothing is more needed to overcome the modernist's snobbishness.”

Now as you can imagine when I discovered this I was inspired to take Einstein to heart and accept both his judgment and his challenge. I don’t think I need to explain much more beyond this. One thing I must include here is that his challenge doesn’t just extend to studying the teachings of antiquity but all the way up to the present. I have striven to do just that within my limits of time and comprehension. It is with this then why Einstein serves as the type of person to represent this contention that not only the “how” is important to the understanding of our world but the “what” and also the “why”. Einstein summed up his personal feelings about this many years ago when he said:

“I want to know how God created this world. I am not interested in this or that phenomenon, in the spectrum of this or that element. I want to know His thoughts; the rest are details.”

I must say I was a little hesitant to quote this as it is so often misused to portray Einstein as someone motivated by religion and so I will clear this up later with another of his quotes. What this truly portrays is that Einstein was not so interested in being able to expand our or his ability to predict as is the main focus of science today, but rather to attempt to understand “what” is the world and “how” it was so conceived which of course is the “why”. Now in regards to Einstein and religion he totally disregarded all of them, as they relate to two categories which he called “the religions of fear” and “the religions of morals”. He summed up his feelings on these when he said:

“And yet, that the primitive religions are based entirely on fear and the religions of civilized peoples purely on morality is a prejudice against which we must guard. The truth is that all religions are a varying blend of both types, with this differentiation: that on the higher levels of social life the religion of morality predominates.”

So it is clear with this that what many would call religion or the will of God is not what Einstein was alluding to. So what was he talking about? This is also revealed in this essay when he says:

“But there is a third stage of religious experience which belongs to all of them, even though it is rarely found in a pure form: I shall call it cosmic religious feeling. It is very difficult to elucidate this feeling to anyone who is entirely without it, as there is no anthropomorphic conception of God corresponding to it.”

So as can be seen the God that most everyone thought that Einstein was referring to was not what it actually was. I will offer no further explanation of this due to the reasons that he cited and yet will tell you that it can be understood if you accept the challenge he offers to all.

Oh yes, I was going to relate to you what “Einstein’s Moon” refers to. Although I intended to include it here, I have decided it important enough that it serve as the discussion of a future entry.

Truth & Beauty, do they still Hold?




It has been some time since I have written in this blog. There are many reasons for this, yet I have to admit the central one was a lack of inspiration. However, recently with the start up of a new blog and topic, some things fell into place which I would like to include here. As you may know that in previous posts I have devoted some time to Plato and the explanation and promotion of his ideas. I believe that you would not be too surprised to learn I am greatly influenced by his teachings . One of the central tenants of platonian thought is that the world is the end result of two things, which I have explained here in the past as being “truth” and “beauty”. These Plato thought formed and explained both the substance and action of our world. He also referred to a second level of reality that was not part of our own world and yet connected. This place as he described was where all things found in our world and all things possible in the past or future, in terms of final form and action exist in their completion. You could describe this as the realm of all possibility. What I would like to discuss here is if such concepts still serve a useful role as to the definition and explanation our world.

When it comes to the broad strokes of the concepts of Plato, for the most part today are referenced as being Metaphysics. The particular form this metaphysics takes is said to be its ontology, or an explicit specification of a conceptualization. The central feature to Plato’s metaphysics is that as far as our world's (reality) is concerned there are two interconnected aspects to it, referred to as “truth” and “beauty”. These aspects correlate in some fashion to form what is the world. This would be considered today as a dual ontology. The other realm I spoke of is a conceptual realm where all of this interaction has played out as to the final form of which all this can take. This of course for many would amount to no more then fantasy, as to how such a conceptualization could actually be relevant to our world. In fact many involved in the physical sciences would say that all relates to quantum physics where the only feature considered as the bases of our reality is a wave or rather action of a wave, that forms what we perceive as all that is real. This could be referred to as a singular or one aspect ontology. With the adoption of this ontology they have in turn ended up with a description of the world that is in many ways both incomplete and bizarre. None the less, despite these obvious features and concerns, it is thought to be a reasonable explanation, since it has proved useful in terms of prediction of outcome which as I have explained is a primary objective within modern science.

Before we go much further, I feel I must give you a little taste of what I mean by this incomplete and bizarre description. It is most poignantly and thereby simple brought out in what is referred to as the two slit experiment. In this experiment you have a device that produces and emits one subatomic particle (quanta) as say an electron at a time. Further on and in front of the emitter is a barrier that has two slits cut into it that are close together but not joined. At some distance beyond this barrier there is a backstop which can record and show the location of every electron that strikes it after they pass through the slits. Now to understand this more fully we have to imagine what would happen if we used bullets with a similar setup instead of electrons. What would appear at the backstop after many bullets fired would be impacts that form a distribution pattern that would be greatest in the centre section of the backstop behind the two slits and diminishing in a downward bell like curve. Now what do you suppose happens in the electron case? Well as with bullets as each electron is emitted there is found a corresponding spot (strike) at the back stop. However after many strikes we observe the pattern of hits being formed is nothing like that in the case of the bullets. This pattern reveals bands of strikes starting at the centre with gaps of no strikes in between with the number of strikes in each band outward (of the middle) diminishing in number. This appears to be a pattern formed by wave interference rather then one of a particle nature. Now the question waves of what? For it is clear that what has struck the screen is single units and yet the pattern they distribute is that of a wave. How can this be? Well the way most physicists explain this is they don’t. There are all kinds of rules about how to make predictions in such situations yet no explanation is offered or no reasonable one at best. When asked the question if the electron, (quanta) are particles or waves? The answers often given is both, neither or it doesn’t apply. If you ask if the electron went through both slits or one? In reply they will say we don't know. In the end many say something to the effect of what Richard Feynman did more the forty years ago (taken from The Feynman Lectures on Physics, Volume 3, page 1-10):

“One might still like to ask: “How does it work?. What is the machinery behind the law?” No one has found any machinery behind the law. No one can “explain” any more than we have just “explained” . No one will give you a deeper representation of the situation. We have no ideas about a more basic mechanism from which these results can be deduced.”

So now you can understand what I mean by incomplete and bizarre. On the other hand if I were to say this to most physicists they would say, that I, not they, have a problem. Now this could be seen as all well and good if what they and Dr. Feynman said was true. However, there has been a reasonable and straight forward explanation of what is called standard non relativist Quantum Mechanics for some time. The explanation was proposed actually twice. First, in 1927 by Louis de Broglie and then again it was independently rediscovered and expanded in 1952 by David Bohm. This theory is known as the de Broglie-Bohm pilot wave theory or more simply as Bohmian Mechanics. This theory explains that the machinery of quantum mechanics is to be found in the resultant action of the influence of a wave over that of a particle. Now how did they miss that one? Everyone was asking “particle” or “wave” when the simple answer was “particle” and “wave”.

Now you might ask, why was this ignored? First you might suspect that both of the discoverers were either unknown or unqualified. Well de Broglie was one of the founders of quantum theory and received a Nobel Prize in 1929 for his contributions to the subject. Bohm on the other hand was a leading physicist of his generation and wrote a text book in 1951 on quantum mechanics that is still widely used to this day. So that doesn’t wash. So then why was it ignored? What I (and others before) contend is the reason relates to this ontology issue. As I stated earlier, standard quantum mechanics is centered on the wave phenomena as being the sole explanation, where all is simply considered as the actions of a wave. Not a normal wave that is, for this wave collapses only upon observation to present or better to be only to be perceived as a particle. Also, there are not any firm or straight forward rules as to when and where this should be considered. So when you boil it all down, it is because they prefer this singlular ontology as opposed to the dual ontology suggested by de Broglie and Bohm.

Now how does all this relate to the Platonian concepts, which are truly the focus of this discussion? In my way of looking at this one could equate Plato’s “truth” with what is seen in the world as to relate in Bohm’s theory as the “particle” aspect of reality. Likewise you could consider Plato’s “beauty” as what gives the world order (direction) as the wave aspect. In this way one could say that although Plato had no idea that the world was the result of a wave's influence over a particle, he did have the concept that such a duality was indeed required. Now what about this other realm I spoke of as Plato imagined.? As it turns out a consequence of Bohm’s theory is that the actual outcomes are decided or better calculated mathematically in what is referred to as “configuration space”. Although this space is not where the entities are actually found, which is what is called real space, it does hold a deep connection with the theory, much more so then then when it is considered in any other application were it has been used. This configuration space is said to be of higher dimension because it expands when each and every particle position is considered in relation to each other. It could be loosely thought of as were all the possibilities are considered and resolved. I would say that fits in with Plato’s conceptualization as well.

To conclude today, I would once again suggest that ancient ideas like Plato’s where both the “how” and “what “are considered, still have application today. This is in contrast to modern physics were the “how” is held so central that the “what” could be ignored or thought as unimportant. Now Plato also spoke of the “why”, which is not addressed directly by Bohm’s theory. Plato said the “why” was for the ”good”. When you examine Bohm’s theory, which realizes both the substance (truth) and the order (beauty) of the world I can’t insist this is the reason or prove it so. I can only hope it is true.

Wisdom’s End






As you are aware, one of the goals of this blog is to explain how, in the modern era, we have ended up with two separate and in many cases diametrically opposed disciplines that claim to expand human understanding. Thus far we have shown that with the ancient Greeks, the two were for the most part still considered one. In contrast to this, we have found that by Newton's time, that the two have for the most part had become separate. Therefore, we can surmise that the shift occurred between these two periods. So perhaps we should then look to what has happened in between. As we know the civilization that in effect absorbed and then for the most part adopted that of the Greeks, was the Romans and their empire. The Roman empire initially began by first conquering the Greeks and thereafter in essence took for there own both their philosophy and religion. The Romans however were more ambitious as to their acquisition of influence and thereby territory. To aid them in thier endeavor, they employed Greek science put into practice to facilitate this.

Science, put into practice in the modern definition is technology. Now the narrow view of technology, is thought by many, to be simply engineering. Which is often in turn described as applied science. I submit that in the Roman case and even more poignantly our own, this is far too narrow a view. I would contend that when science is considered to be the practical basis for ones society, it tends to effect and hence shapes all aspects of human endeavor. Now for the Romans, at the outset, they incorporated the Greek ideas in a more holistic sense, as the Greeks themselves had for the most part. Where the expansion of human understanding was taken in the spirit of the exploration of nature and its design, as to how it applied not only to man, but the world as a whole. From this perspective they could form their society on what could be perceived as natural principles. The Greeks viewed things from the perspective of introspection, where this introspection would lead to virtuous individuals that would then form themselves into a thus virtuous society or state. Socrates often was contended to have proclaimed:

"Know thyself,"
To extend this in terms of society as a whole he was known to insist:

"the unexamined life is not worth living."
At the beginning with the adoption of these ideas, the Romans, more or less, mirrored the aspirations of the Greeks. However, later on, when ambitions for Rome extended beyond the Greek concept of city state, to expand to empire, the view and therefore the methods changed. along with the course and thereby the destiny of their society. To accomplish this expansion, the Romans turned away from the Greek ideals that philosophy served to expand the understanding of nature, to focus more on its practical application, in the service of man. Also, what started out as the semblance of a democratic social order, in the service of its citizenry, transformed into a dictatorial system, in the service of empire building. This in turn, inevitably lead to forces of discontent from both inside and out to question the basis of the very authority of Rome. One of these primary forces were manifest in a new emerging philosophy and that was Christianity. In the spirit of the history of Rome when they found one could not destroy a thing, one then incorporates it. This was the case with Christianity. At first emperor Constantine admitted its followers freedom of practice, returned confiscated property and gave land and tax free status to the new founded church. Later emperor Theodosius made it the official religion and banned all others with the closing of what he declared the pagan temples. The last stroke was that of emperor Justinian, in 529 A.D., with his order closing the last of the Greek schools of philosophy at Athens and the banning of such studies.

So how, you might ask, did this act to serve Rome or rather its rulers? From my viewpoint, forces inside the empire started to question the authority of the emperors. For it did not appear to serve the people, as it had once with the long past democratic system. This authority was brought further into question, since the new budding philosophy professed the equality of all men in the eyes of their creator. How then were the rulers going to maintain control in the face of this? The solution, adopt the new philosophy, bane the others and thereafter claim that their authority was given to them by this new God himself. This concept which became tradition has continued to this day and has even been incorporated into the newly created democracies in one guise or another.

Now I don't want you to take me wrong, for I have no political agenda in all this. Nor am I attempting to lay blame on the Christian or any other related philosophy. My sole intent is to set up the context and background as to how and why this split occurred between science and philosophy. For what I contend is, that with the banning of Greek philosophy and methods, for political ends, is what effectively began the then slow process as to what manifested itself into the roles of science and philosophy as observed today. Essentially, this policy, at first halted the expansion of understanding, in philosophic terms, as defined by the Greeks and along with it much of the knowledge gained. Also, it created a tension that would force any new emergence of renewal of such, to avoid conflicting with the new religious philosophy, in terms of its authority. Primarily what I'm referring to, is any aspect that might serve to address the question "why", beyond what this new philosophy so dictated.

In future posts, we will expand on all this, to discover how this new face of science emerged in the early years. We will also find, that ironically the very philosophy that in effect became the instrument used (or more properly misused), as reason to banish the old philosophies became the depository and keeper of this then forbidden wisdom. We will learn of the early practitioners, as to from whence they came and what they did in terms of expansion of human understanding. We will discover the limits placed on them and how this in turn served to shape our modern concept of science. However, for now all of this must wait to be explained in upcoming entries.

Cycle and Epicycle, Orb in Orb








In the course of this blog, I have been speaking about this contention of mine, that the split between science and philosophy is focused around who addresses the “how” questions and who deals with the “why” ones. I’ve shown that for the most part, science sticks to “how” and leaves the “why” to philosophy. Lately, in particular, I have been speaking about the scientific method, as to what it contains or allows, as well as what it does not. One of the key elements of the method, is the use of mathematics. Now as we know one of the most basic tools in science, is mathematics. In fact many mathematicians would claim that it is the most fundamental of the sciences, rather then physics. There are others that would say that mathematics is not a science at all, but rather a hybrid of logic. However, the purpose of this post is not to enter this debate. What I would like to talk about is how mathematics itself, to a large extend, mirrors the rest of science in the context of how it forms our attitudes in regards to the discovery of truth in the natural world. To be fair I should say our common view. The example I will use to expand on all this is a mathematically defined shape that all of us are familiar with and that is a circle.

Now to begin, if I asked you to describe a circle, what comes to mind? This would seem to be a easy question, yet if I were to take to the street and solicit answers from a cross section of the populous, I suspect I would get a variety of replies. Some might say, it’s the shape we see when we look at a wheel. Others might say it’s the shape we see when we look at the moon or the sun. The more scientific might give a explanation that is somewhat more technical. In general though, I would suspect that most people would draw on things found in nature or constructed by man to describe it. This said , I would also wager that when you think of a circle, you see it in the abstract, as to what it is without reverence to any physical object. Now if you were to look for a formal definition, what would you find? Well I looked to many sources, including several dictionaries. For instance in all dictionaries I referred to, the one given was almost identical to the following, stated in Webster’s online dictionary as:

"a closed plane curve every point of which is equidistant from a fixed point within the curve"
For a more professional definition one might refer to Wolfram’s Math World (a site I highly recommend), yet in this case it states much the same:

"A circle is the set of points in a plane that are equidistant from a given point."
Now what is the difference between what many of you describe or only hold in your mind and what we find here as a definition. The difference is, in your mind, you hold it as a preformed thing, in its completion or “what” it is. In the definition, what is being described is “how” it is, as to how you would go about constructing a circle. Like the task performed when you use a compass to create one. This definition also, in a indirect way,both implies and relies on another abstract concept and that is the one of infinity. For the points described must be both infinite in number and have no space between them, otherwise one ends up with something that although circle like, would still not be a true circle. So is there another way to describe a circle, which does not rely on a reference to other objects or ill defined abstract concepts?

Before I reveal this other way to describe a circle, let’s first review what I told you were the key “hunches” that science uses to find truth in the natural world. There were two. One was economy and the other was symmetry. Now let’s suppose that we are nature. In this case I will limit us to be nature of a two dimensional world. That is, one that is restricted to a plane or flat land. Now let’s suppose, we as nature, constructed this world to comply with these hunches I pointed out. So if we imposed these hunches as our rules to make real, a basic and fundamental shape for this universe, what could be one that we would end up with? Okay, let’s imagine we say we want a two dimensional form, that always is in proportion, a line of least length to enclose the greatest amount of area . For as I said, we are nature and so therefore we want our basic structures economical in both form and explanation. So what form would we have thus just demanded? Well as I think you will have guessed, if you didn’t know already, it is the circle. Now what about the symmetry part? Remember we defined symmetry as when one takes a thing and does something to it in regards and respect to the allowed levels of freedom (dimensions) and it there after remains unchanged. What can we do to the circle to see if it has symmetry? First, we could just move it around our two dimensional universe. When we do this, ( to no great surprise) no matter to what distance moved, it still remains the same in both form and function. Now what if we rotated it as allowed in this universe, will it change? No it will not. So now we have found by invoking this rule of economy, we have in turn ended up with something that also demonstrates symmetry. Now you might retort, that’s fine for this mystical flat land, but what of the real world. In response, I would remind you that the three dimensional projection or analogue of the circle is the sphere. The sphere described in the way I have just shown, would be a form that always is in proportion the surface of least area enclosing the greatest amount of volume. The economy here is also evident and the tests we imposed to confirm symmetry, would hold the same.

Now you say, so what, for the objects just described are simply abstractions. You continue by insisting they are therefore forms only created in our minds. You could thus feel this should end it all. That would be true, if the circle and its somewhat distorted cousin the ellipse were not so prominent in both the form and action of our natural world. That it is to say, it has proven to thereby have purpose. The other way to state it is, “why” is the circle (or the sphere)? The answer of course is to have a entity(s) that can act in purpose that is both economical and symmetrical in form and function. I thus find it unfortunate, that although science looks to these hunches to discover truth of the world, that it at the same time denies the “why”, that also lends insight into not only the means of it’s construction, but also of its utility.

In summation today, I would bet in the beginning, when I mentioned mathematics many of you thought, oh no, here come the formulas and equations. In contrast to this expectation, as demonstrated above, many might be surprised to find that if they explored both mathematics and science, at the more fundamental level, you may discover it to be simple, beautiful and yet excitingly mysterious. I would ask now, the next time you are given to describe a circle, what will be your reply?

As a foot note to this, let me leave you with a quote from Milton’s “Paradise Lost” that I find projects the spirit of what I have attempted to convey:

From man or angel the great Architect
Did wisely to conceal, and not divulge
His secrets to be scanned by them who ought
Rather admire; or if they list to try
Conjecture, he his fabric of the heav'ns
Hath left to their disputes, perhaps to move
His laughter at their quaint opinions wide
Hereafter, when they come to model heav'n
And calculate the stars, how they will wield
The mighty frame, how build, unbuild, contrive
To save appearances, how gird the sphere
With centric and eccentric scribbled o'er,
Cycle and epicycle, orb in orb.

Reason Denied







With my last post I spoke of Francis Bacon and the mark he left on modern science with his method. I also pointed out, how this proposed method was later championed by none other than Isaac Newton. Further, it was indicated that the base premise of the method, is that there was not to be taken anything that could be considered as a preconceived truth or foreknowledge as a premise. In so that, the only things that could be used as such, where those that had been established by inductive reasoning suggested and confirmed through methods of experimental observation. What I also demonstrated was that this method denies that man has the capacity to know anything that is simply a given despite what I had shown earlier, that science truly could not function without such notions. At the conclusion, I stated there were those, that have denied this program to some extent to contest there are things that we simply know which can be used within the context of “why”, to further our understanding of the world. One such person was René Descartes (1596-1650)

René Descartes was a philosopher, mathematician and physicist. His obvious and best known contribution to mathematics and thereby science is in the founding and development of what is referred to as analytical geometry. This of course is the considering of geometry in the back drop of algebra. It also in turn lends algebra spacial qualities. What many of us, are most familiar with in this regard, is the plotting of algebraic formulas in as to represent space plotted in relation to defining number lines. These are of course known as Cartesian coordinates, named in his honour. This also formed the foundation from which Newton and Leibniz later created calculus. Now if this were not enough, Descartes is also considered the founder of modern philosophy. On the subject of Descartes and philosophy, I will speak in more depth in future posts. For now though, I would like to focus on his thoughts of what the expansion of knowledge should be in terms of science and the method it should follow.

Descartes, as Bacon, was suspect and concerned about what could be considered true. However, in contrast to Bacon, Descartes insisted that deductive rather than inductive reasoning should serve as the base logic for the scientific method. Now this deductive process wasn’t that of the then common type, where one could declare just about anything as the base premise or axiom in terms of what is then to be considered and thus deduced. To illustrate more clearly what form this took, I quote here from his paper entitled, Discourse on The Method: of Rightly Conducting The Reason, and Seeking Truth in the Sciences (1637)

“Among the branches of philosophy, I had, at an earlier period, given some attention to logic, and among those of the mathematics to geometrical analysis and algebra, -- three arts or sciences which ought, as I conceived, to contribute something to my design. But, on examination, I found that, as for logic, its syllogisms and the majority of its other precepts are of avail- rather in the communication of what we already know, or even as the art of Lully, in speaking without judgment of things of which we are ignorant, than in the investigation of the unknown; and although this science contains indeed a number of correct and very excellent precepts, there are, nevertheless, so many others, and these either injurious or superfluous, mingled with the former, that it is almost quite as difficult to effect a severance of the true from the false as it is to extract a Diana or a Minerva from a rough block of marble.”
Here we discover that Descartes, much like Bacon, was concerned with what could be considered true. In the next quote he states that he was in search of a method for science that would contain reliability and precision for he says:

“I was induced to seek some other method which would comprise the advantages of the three and be exempt from their defects.”
So what Descartes has said is that although there is much that is true in what he considered the somewhat unreliable sciences, he needed to find a method by which the reliability and thus the utility of science could be improved. To begin he lays out his method in four parts, the first being as follows:

“The first was never to accept anything for true which I did not clearly know to be such; that is to say, carefully to avoid precipitancy and prejudice, and to comprise nothing more in my judgement than what was presented to my mind so clearly and distinctly as to exclude all ground of doubt.”
Here as Bacon had stated, all should be considered with the element of doubt, where nothing can be simply taken as a given. However, unlike Bacon, Descartes has already suggested, that there are some things that by there very nature can be taken as true. He also suggests that this judgement is to be found within ones self and not externally. Something that I would view as almost considered instinctive reason, for lack of a better term. The next step he states as:

“The second, to divide each of the difficulties under examination into as many parts as possible, and as might be necessary for its adequate solution.”
Here again, just as Bacon had insisted, things must be first broken down into all things that might be considered. Now Descartes next step is explained in the following.

“The third, to conduct my thoughts in such order that, by commencing with objects the simplest and easiest to know, I might ascend by little and little, and, as it were, step by step, to the knowledge of the more complex; assigning in thought a certain order even to those objects which in their own nature do not stand in a relation of antecedence and sequence.”
Still from what has been said, the methodology of Bacon and Descartes are looking pretty much the same as Descartes says that not only should ideas be broken down into the smallest parts possible. He futher suggests they be assigned order, whether or not they at first appear to have priority of importance or that of connectivity of structure. He is talking about acending in small steps, which would normally relate to a bottom up approach, which on the face of it looks like a inductive process. He completes his four steps with the following:

“And the last, in every case to make enumerations so complete, and reviews so general, that I might be assured that nothing was omitted.”
Now at this point you may be confused, as to why I consider there is a distinction to be made between Bacon and Descartes in terms of their methods. From what has been revealed up to now, it appears that Descartes is just restating what Bacon said some 17 years prior, without perhaps the mention of observation, although it has not been excluded. It also seems to be shaping up to be performed within a inductive frame work, that would be satisfied as in Bacons method, only through exhaustion. But now in the following we find that the system of reasoning that Descartes insists to be primary in its execution, is not induction at all, for he now states;

“The long chains of simple and easy reasonings by means of which geometers are accustomed to reach the conclusions of their most difficult demonstrations, had led me to imagine that all things, to the knowledge of which man is competent, are mutually connected in the same way, and that there is nothing so far removed from us as to be beyond our reach, or so hidden that we cannot discover it, provided only we abstain from accepting the false for the true, and always preserve in our thoughts the order necessary for the deduction of one truth from another.”
Despite the similarity in the preamble, we now discover, that what Descartes has in mind as the principle method of reasoning, is that of deduction and not of induction. It's not hard to imagine why Descartes feels this way, for as I mentioned before and he himself here eludes, that he was also a great mathematician. Mathematics in the main is a deductive process, building from what are referred to as axioms, that are used as premises, to deduce further truths. Bacon on the other hand, avoids for the most part this method and not surprisingly so, for he was not a mathematician as was Descartes. Bacons primary training and occupation, was that of a lawyer. In the few scientific explorations he did conduct, he excluded the use of mathematics almost entirely. I must also relate, that he had little success. Now that Descartes has set up this program of discovery, he finds himself with a bit of a dilemma, as now, what is he going to use as his axiom(s), to begin this step by step deductive process? After all, he has, as Bacon did earlier, dismissed all prior known truths. What then is he going to utilize as his foundation on which to build his deductive method? Here we now witness Descartes in his eureka moment, for he states;

“But immediately upon this I observed that, whilst I thus wished to think that all was false, it was absolutely necessary that I, who thus thought, should be somewhat; and as I observed that this truth, I think, therefore I am (COGITO ERGO SUM), was so certain and of such evidence that no ground of doubt, however extravagant, could be alleged by the sceptics capable of shaking it, I concluded that I might, without scruple, accept it as the first principle of the philosophy of which I was in search.”
Now Descartes has discovered, his first and primary truth, from which he proposes that all the others will follow and in turn proved is to be, he “thinks” so therefore he “is”. He contends here he has found the bedrock truth that he feels that no one can dispute and that is they exist. This, like many other statements in history, have been repeated so many times, that they tend to become completely misunderstood. Some for instance imagine, that this means that only things that “think”, “are“. That is because many do not understand the deductive process, for they imagine that like a equation this suggests that (think = am). That would mean that to write (am = think) is the same. Now to compare, what if I said , I “walk” so therefore I “travel”. If this were then interchangeable, you could say, since I “travel” so therefore I “walk”. I don’t know about you, but I take the bus some times. Also, it could thus be suggested, that baseballs have legs. No, deductive reasoning is very precise, for it only holds that what is deduced from the premise is true, not that it is equal to the premise.

So now we have discovered, that Descartes has proposed a method, in which the deductive process serves as its primary system of logic. It must be also made clear that he does not entirely omit the inductive process, which in science is rooted in its observations. He however warns, that in these observations that deduction must also play a role for as he states:

“But this is certain, and an opinion commonly received among theologians, that the action by which he now sustains it is the same with that by which he originally created it; so that even although he had from the beginning given it no other form than that of chaos, provided only he had established certain laws of nature, and had lent it his concurrence to enable it to act as it is wont to do, it may be believed, without discredit to the miracle of creation, that, in this way alone, things purely material might, in course of time, have become such as we observe them at present; and their nature is much more easily conceived when they are beheld coming in this manner gradually into existence, than when they are only considered as produced at once in a finished and perfect state.”
What Descartes is pointing out with this, is that to observe something as it is and then therefore suppose it is, as it was always, is a mistake. Therefore, one must also consider it may have come from something or things simpler perhaps and to look to this also as a possible explanation of outcomes in observation. He is saying that induction is therefore vulnerable with this flaw and it is only by deduction that we may be able to avoid this. What is also interesting to note, is that this is turn would later serve as the seeds of discoveries, such as Darwin’s. In as Descartes suggests with this, that the world is not so much a place of being, but rather a place of becoming, as to what it will be. It is of no wonder with such thoughts, that shortly after his death, the Vatican put some of his writings on the forbidden reading list.

Now once again we have come to the question, so what is my point? Actually I have a few. The first, is to indicate the differences between the methods of deductive and inductive reasoning, when used as science’s base. In the inductive process, where observation plays the primary role, truth is formed by consensus or the weight of evidence rooted in a statistical background. If all the available observations support a conclusion, then it is considered to be true. In the deductive process, truth is only established with reason derived from a premise, which is a self evident truth or has been before deduced from one. Both are processes that attempt to relieve doubt. However, in the inductive process, with nothing pre-established as truth, what is proposed is only as good as the observations taken and the methods so used to consider them. In deductive reasoning, everything is derived from the premise, the only remaining doubt is that of the soundness of the initial truth and the correctness of the connections made with subsequent deductions. In deduction, we must look to the premise and only that to be sure. In induction, we have to not only trust our observations, as to their quantity, but also the quality of them. It must be also assured that the inductive statement then formed is a strong one, in the context of the data collected. In the deductive process, the demanded first requirement is to initially ask “why”. To realize this, lets look to what Descartes must have done to come up with his initial premise. He would have had to at first asked, “why” am I certain that I “am“? His answer would then have followed because I “think”. With this one may see more clearly that the function of “why”, is to lend certainty to man's understanding and thereby of nature's, so that we might have firm footing to further explore its aspects of purpose and thereafter perhaps its utility, in concert with other means presented or at our disposal. This is what Descartes so discovered and which I most certainly agree is so.

As a post script to this, I would like to address as to what happened to Descartes ideas, in the context of their current application to science. Descartes today, is viewed as primarily a philosopher and by many a great one at that. He is not however, considered much as a scientist, despite the fact that he is also acknowledged as the founder and father of analytical geometry, that science still covets and from which also Newton required in the course of discovering calculus. I would contend, that not only for his refinement and promotion of this deductive method, which I have attempted to explain, but also stressing that the “why”, plays a role in understanding, that he was then so dismissed. As evidence of this, I will make one final quote. This quote is of Voltaire, who discussed in the following, just what I have contented. Here he is to be found using Newton as the comparison in this regard upon a visit to England in the mid 1700‘s. ;

We may admire Sir Isaac Newton on this occasion, but then we must not censure Descartes.
The opinion that generally prevails in England with regard to these new philosophers is, that the latter was a dreamer, and the former a sage.
Very few people in England read Descartes, whose works indeed are now useless. On the other side, but a small number peruse those of Sir Isaac, because to do this the student must be deeply skilled in the mathematics, otherwise those works will be unintelligible to him. But notwithstanding this, these great men are the subject of everyone's discourse. Sir Isaac Newton is allowed every advantage, whilst Descartes is not indulged a single one. According to some, it is to the former that we owe the discovery of a vacuum, that the air is a heavy body, and the invention of telescopes. In a word, Sir Isaac Newton is here as the Hercules of fabulous story, to whom the ignorant ascribed all the feats of ancient heroes.
So to conclude, I would submit, that the fear Voltaire expressed as to the fate of Descartes and thereby his ideas, has come to pass. It is then not to wonder, why, lesser persons choose not to follow the route of Descartes, but rather that of Newton's, to avoid such. This then is not to say that no one has since. As there have been a few. These few in turn, have also broadened the insight of humanity and yet as Descartes, have in there own way also been made to pay the price. About these people and other related things I will continue to speak of in future posts.

The Dawn of Reason?




It has been about a week since my last entry. The longest stint since beginning this blog. You have my apologies for this, yet it seems whenever I turn my thoughts to the subject of time, as I had in my last post, it sets my head into a protracted wonder mode. When this happens all other thoughts seem to end up on the back burner. With this said what it is I’d like to return to today, is this subject of “how” and “why” this split between science and philosophy occurred. When I last addressed this I was speaking of Newton and what his thoughts on the expansion of human understanding and it’s methods were. What we discovered was although Newton was certain there was a underlying scheme to nature, he was also equally certain, that asking the “why” question would not serve to help discover it. Basically what he thought is as many do today, that science will only extend human understanding by focusing on the “how” questions, through what he indicated was already a predescribed method. He synopsised this method as you recall in saying:

“In this philosophy particular propositions are inferred from the phænomena, and afterwards rendered general by induction.”

This on the face of it looks like a very straight forward statement. However, if examined more closely you find it to be something quite complex. The first thing that could be misunderstood is perhaps the only system of logic that is utilized by the modern science is that of induction. One also has to understand that this induction is not of the common type, for it would be better described as induction through exhaustion. This is what I previously described as the “typing monkey method”. Let’s first take a definition of inductive reasoning from Wikipedia:

“Induction or inductive reasoning, sometimes called inductive logic, is the process of reasoning in which the premises of an argument support the conclusion but do not ensure it.”

Now as many of you know, inductive reasoning, while useful, has the central flaw of not on its own being all that reliable. Also, inductive statements are further categorised generally into two types, which are “strong” and “weak”. An example of a strong inductive statement would be, “ all observed polar bears are white so therefore all polar bears are white”. The first problem here is that it is assumed that every polar bear has been observed and of course that is not the case. The second is if we find a bear that is say, black instead of white, although living in the artic, does this mean therefore it is not a polar bear. The weak inductive statements can pose even greater difficulty. An example of this might be, “ All my pants have zippers so therefore all pants have zippers". I don’t think I need to point out where the fault is with this. So now one might assume that the whole method could be flawed if solely dependant on induction. Happily it is not, for it also is dependant on what is called deductive reasoning. This however is not all that self evident in Newton’s statement, as it has been disguised or belittled somewhat as the word “inferred”. What then does “infer” mean. The Oxford defines it as “to deduce or conclude”. In the “Free Dictionary” its defined as “To conclude from evidence or premises”. So now let’s look at what deductive reasoning is. Again from Wikipedia they state:
Deductive reasoning is reasoning in which the conclusion is necessitated by previously known facts - the premises: if the premises are true, the conclusion must be true

So now then, how does this differ from the inductive method? As a example of a deductive statement one could assert," in as the polar bear is above the ice sheet, and since the ice sheet is above the earth, therefore the polar bear is also above the earth.". Now deductive process can also be flawed if the connection between what is considered the premise and what is deduced has not been truly established as a commonality. For instance I might say: All polar bears dislike the heat, I dislike the heat, so therefore I am a polar bear. In general, the process of deduction is dependant on first sighting self evident truths, so then if they are true so is your conclusion. As can be seen here, we have two systems, which in a sense could be considered diametrically opposed. Induction, were nothing is assumed true, nor can it be and deduction, where some things are taken as true by their nature or taken as a given. This is then what would appear to be two incompatible systems that science uses to expand its knowledge of the natural world.

But how can this be accomplished? Well the way this has been carried out for the most part is to minimize the use of the deductive process and when one cannot in some sense disguise it. The deductive process for the most part lay hidden from view to many inside what are its mathematical formalisms and also the hunches I have previously mentioned. The part that is there for all to see is the inductive process, were everything is suspect and nothing assumed. This is considered by many not only to be the core but also the strength of modern science.

So once again you might ask, how did we end up here? Now as I have relayed before, it is not something that appeared out of thin air. It is rather something that has occurred over the course of time within the context of certain events. What I can say is, that there was a time, a place and a person in which all this crystallized, to take what is for the most part its final form, as it is perceived today. The time was 1620. The place was London, England and that person was Francis Bacon. The crystallisation, as I have so called it, was with a paper I have before mentioned, entitled, “Novum Organum” or “New Instrument”, for those who were not required to study Latin. In this paper Bacon outlined and promoted a method by which he said man in general and science to be specific must follow, if it hoped to significantly improve human understanding of the natural world. Now I've considered the ways I might explain and portray the nature and focus of this document, for there appeared to be many. It then should be established that Bacon thought that the inductive method or what would be better expressed as Bacon's inductive process, is the meat of what he viewed as the true methodology for all of science. Let’s first confirm what Bacon had in mind as to the utility and scope of his proposed method. In the introduction of his treaties he states:

“But if there be any man who, not content to rest in and use the knowledge which has already been discovered, aspires to penetrate further; to overcome, not an adversary in argument, but nature in action; to seek, not pretty and probable conjectures, but certain and demonstrable knowledge — I invite all such to join themselves, as true sons of knowledge, with me, that passing by the outer courts of nature, which numbers have trodden, we may find a way at length into her inner chambers.”

As one can see here Bacon had both great hope and aspirations for what he considered his new method. In fact, in some sense he was correct to make such a boast, for his method for the most part, still serves today as the blue print of science.

Now does Bacon stop at natural philosophy. Let’s quote him again from this document as he proposes the following:

“It may also be asked (in the way of doubt rather than objection) whether I speak of natural philosophy only, or whether I mean that the other sciences, logic, ethics, and politics, should be carried on by this method. Now I certainly mean what I have said to be understood of them all; and as the common logic, which governs by the syllogism, extends not only to natural but to all sciences, so does mine also, which proceeds by induction, embrace everything.”

Here we find that this method is proposed to govern and guide all mans conception and aspirations of truth along with its resultant considered actions. It could be argued that Bacon’s insight and ambition for the most part has held sway in terms of the form and condition of our society and its thinking. Now here you will find that Bacon held induction as the key and central tenet of this method. No
