Physicists From The United Kingdom

"People who get Nobel prizes aren't necessarily the most imaginative of people. People who sometimes find a system, develop a system, do very useful work."

"The properties of bodies were investigated by several distinguished French mathematicians on the hypothesis that they are systems of molecules in equilibrium. The somewhat unsatisfactory nature of the results... produced... a reaction in favour of the opposite method of treating bodies as if they were... continuous. This method, in the hands of Green, Stokes, and others, has led to results the value of which does not at all depend on what theory we adopt as to the ultimate constitution of bodies."

"It is very difficult for us, placed as we have been from earliest childhood in a condition of training, to say what would have been our feelings had such training never taken place."

"I like teaching and the contact with young minds keeps one on one's toes."

"I do not know of anything in modern poetry as violently hostile to contemporary life as was the poetry of T. S. Eliot, which so perfectly fitted the mood of the young people between the two wars. I also find much more benevolence towards humanity in younger historians than there was in Spengler or in Toynbee. Still, it is not difficult to sense the disgust of the intellectuals at the new prosperous working class, 'with their eyes glued to the television screen,' who have become indifferent to radical ideas."

"The future cannot be predicted, but futures can be invented. It was man's ability to invent which has made human society what it is."

"It would be pleasant to believe that the age of pessimism is now coming to a close, and that its end is marked by the same author who marked its beginning: Aldous Huxley. After thirty years of trying to find salvation in mysticism, and assimilating the Wisdom of the East, Huxley published in 1962 a new constructive utopia, The Island. In this beautiful book he created a grand synthesis between the science of the West and the Wisdom of the East, with the same exceptional intellectual power which he displayed in his Brave New World. (His gaminerie is also unimpaired; his close union of eschatology and scatology will not be to everybody's tastes.) But though his Utopia is constructive, it is not optimistic; in the end his island Utopia is destroyed by the sort of adolescent gangster nationalism which he knows so well, and describes only too convincingly. This, in a nutshell, is the history of thought about the future since Victorian days. To sum up the situation, the sceptics and the pessimists have taken man into account as a whole; the optimists only as a producer and consumer of goods. The means of destruction have developed pari passu with the technology of production, while creative imagination has not kept pace with either. The creative imagination I am talking of works on two levels. The first is the level of social engineering, the second is the level of vision. In my view both have lagged behind technology, especially in the highly advanced Western countries, and both constitute dangers."

"Incomplete knowledge of the future, and also of the past of the transmitter from which the future might be constructed, is at the very basis of the concept of information. On the other hand, complete ignorance also precludes communication; a common language is required, that is to say an agreement between the transmitter and the receiver regarding the elements used in the communication process... [The information of a message can] be defined as the 'minimum number of binary decisions which enable the receiver to construct the message, on the basis of the data already available to him.' These data comprise both the convention regarding the symbols and the language used, and the knowledge available at the moment when the message started."

"The belief that there is only one truth and that oneself is in possession of it, seems to me the deepest root of all that is evil in the world."

"I believe there is no philosophical high-road in science, with epistemological signposts. No, we are in a jungle and find our way by trial and error, building our road behind us as we proceed. We do not find signposts at crossroads, but our own scouts erect them, to help the rest."

"If God has made the world a perfect mechanism, He has at least conceded so much to our imperfect intellect that in order to predict little parts of it, we need not solve innumerable differential equations, but can use dice with fair success."

"Can we call something with which the concepts of position and motion cannot be associated in the usual way, a thing, or a particle? And if not, what is the reality which our theory has been invented to describe? The answer to this is no longer physics, but philosophy. … Here I will only say that I am emphatically in favour of the retention of the particle idea. Naturally, it is necessary to redefine what is meant. For this, well-developed concepts are available which appear in mathematics under the name of invariants in transformations. Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects. From this point of view, the present universally used system of concepts in which particles and waves appear simultaneously, can be completely justified. The latest research on nuclei and elementary particles has led us, however, to limits beyond which this system of concepts itself does not appear to suffice. The lesson to be learned from what I have told of the origin of quantum mechanics is that probable refinements of mathematical methods will not suffice to produce a satisfactory theory, but that somewhere in our doctrine is hidden a concept, unjustified by experience, which we must eliminate to open up the road."

"Intellect distinguishes between the possible and the impossible; reason distinguishes between the sensible and the senseless. Even the possible can be senseless."

"I am now convinced that theoretical physics is actually philosophy. It has revolutionized fundamental concepts, e.g., about space and time (relativity), about causality (quantum theory), and about substance and matter (atomistics). It has taught us new methods of thinking (complementarity), which are applicable far beyond physics."

"The continuity of our science has not been affected by all these turbulent happenings, as the older theories have always been included as limiting cases in the new ones."

"I must give some attention to the delicate question of religion, on which I have touched already. In my father's generation this question still was discussed with passion. Since then a sort of truce has existed in the countries of the West, while in the communist states of the East atheism has been made into the State religion. It is not advisable to blow on the embers of such controversies. But as I am talking about the limitations of our physical world picture I cannot but say that I do not believe in transgressions of the laws of nature. As these laws are of a statistical nature, and therefore allow deviations from the norm, I must define more clearly what I mean. The statistical deviations themselves obey certain laws. The miraculous events of religious tradition, however, are of a different kind, they lie on a different plane altogether; they are meant to prove something lying entirely beyond scientific consideration, such as the power of prayer, the intervention of divine power for or against certain men or nations."

"It is true that many scientists are not philosophically minded and have hitherto shown much skill and ingenuity but little wisdom."

"I... refer to the... Waynflete Lectures given by... E. D. Adrian, on The Physical Background of Perception because the results of physiological investigations seem... in perfect agreement with my suggestion about the meaning of reality in physics. The messages which the brain receives have not the least similarity with the stimuli. They consist in pulses of given intensities and frequencies, characteristic for the transmitting nerve-fiber, which ends in a definite place in the cortex. All the brain 'learns' (I use... the objectionable language of the 'disquieting figure of a little hobgoblin sitting... aloft in the ') is a distribution or a 'map' of pulses. From this information it produces the image of the world by a process which can metaphorically be called a consummate place of combinatorial mathematics: it sorts out of the maze of indifferent and varying signals invariant shapes and relations which form the world of ordinary experience."

"There are metaphysical problems, which cannot be disposed of by declaring them meaningless. For, as I have repeatedly said, they are "beyond physics" indeed and demand an act of faith. We have to accept this fact to be honest. There are two objectionable types of believers: those who believe the incredible and those who believe that "belief" must be discarded and replaced by "the scientific method.""

"The scientist's urge to investigate, like the faith of the devout or the inspiration of the artist, is an expression of mankind's longing for something fixed, something at rest in the universal whirl: God, Beauty, Truth. Truth is what the scientist aims at. He finds nothing at rest, nothing enduring, in the universe. Not everything is knowable, still less predictable. But the mind of man is capable of grasping and understanding at least a part of Creation; amid the flight of phenomena stands the immutable pole of law."

"The dance of atoms, electrons and nuclei, which in all its fury is subject to God's eternal laws, has been entangled with another restless Universe which may well be the Devil's: the human struggle for power and domination, which eventually becomes history. My optimistic enthusiasm about the disinterested search for truth has been severely shaken. I wonder at my simplemindedness when I re-read what I said on the modern fulfilment of the alchemists dream: "Now however, the motive is not the lust for gold, cloaked by the mystery of magic arts, but the scientists' pure curiosity. For it is clear from the beginning that we may not expect wealth too." Gold means power, power to rule and to have a big share in the riches of this world. Modern alchemy is even a short-cut to this end, it provides power directly; a power to dominate and to threaten and hurt on a scale never heard of before. And this power we have actually seen displayed in ruthless acts of warfare, in the devastation of whole cities and the destruction of their population."

"In combination with other infernal contraptions, like rockets to deliver bombs at large distances, chemical, biological and radioactive poisons, such a war must mean a degree of human suffering and degradation which is beyond the power of imagination. No country would be immune, but those with highly developed industry would suffer most. It is very doubtful whether our technological civilization would survive such a catastrophe. One may be inclined to regard this as no great loss, but as a just punishment for its shortcomings and sins: the lack of productive genius in art and literature, the neglect of the moral teachings of religion and philosophy, the slowness to abandon outdated political conceptions, like national sovereignty. Yet we are all involved in this tragedy, and the instinct of self-preservation, the love of our children, makes us think about a way of salvation."

"America has grown by expansion in a practical vacuum; the pioneers of the West had to overcome terrific natural obstacles, but negligible human resistance. The Russia of today had to conquer not only natural but human difficulties: she had to break up the rotten system of the Czars and to assimilate backward Asiatic tribes; now she has set herself the task of bringing her brand of modernization to the ancient civilizations of the Far East. For this purpose it is indispensable to have a well-defined doctrine full of slogans, which appeals to the needs and instincts of the poverty-stricken masses. Thus one understands the power which Marx's philosophy has gained in the East. What can we scientists do in this conflict? We can join the spiritual, religious, philosophical forces, which reject war on ethical grounds. We can even attack the ideological foundations of the conflict itself. For science is not only the basis of technology but also the material for a sound philosophy."

"The world of Man's experience is infinitely rich and manifold, but chaotic and involved with the experiencing being. This being strives to arrange his impressions and to agree with others concerning them. Language and art, with their numerous modes of expression, are such ways of transmission from mind to mind, complete in their way where objects of the sense-world are concerned, but not well suited to the communication of exact ideas concerning the outer world. This marks the beginning of the task of science. From the multitude of experiences it selects a few simple forms, and constructs from them, by thought, an objective world of things. In physics, all 'experience' consists of the activity of constructing apparatus and of reading pointer instruments. Yet the results thereby obtained suffice to re-create the cosmos by thought. At first images are formed which are much influenced by observation; gradually, the conceptions become more and more abstract, old ideas are rejected and replaced by new ones. But, however far the constructed world of things departs from observation, nevertheless it is indissolubly linked at its boundaries to the perceptions of the sense, and there is no statement of the most abstract theory that does not express, ultimately, a relation between observations. That is why each new observation shakes up the entire structure, so that theories seem to rise and fall. This, however, is precisely what charms and attracts the scientist. The creation of his mind would be a melancholy thing, did it not die and come to life once more."

"He [Einstein] calls my way of describing the physical world 'incomplete'; in his eyes this is a flaw which he hopes to see removed, while I am prepared to put up with it. I have in fact always regarded it as a step forward, because an exact description of the state of a physical system presupposes that one can make statements of infinite precision about it, and this seems absurd to me. It seems to me that I have followed Einstein's own way of thinking in accordance with his theory of relativity, which recognizes the impossibility of locating any point in time and space absolutely, and therefore concludes that the concept of absolute place and time determination does not make sense. This is at the base of the whole of his mighty edifice. But he did not want to acknowledge the analogy of the situation in the quantum theory."

"While Born evidently realised that our extended order no longer gratified primitive instincts, he too failed to examine closely the structures that create and maintain this order, or to see that our instinctual morals have over the past five thousand years or more gradually been replaced or restrained. Thus, although perceiving that 'science and technology have destroyed the ethical basis of civilisation, perhaps irreparably', he imagines that they have done so by the facts they have uncovered rather than by their having systematically discredited beliefs that fail to satisfy certain 'standards of acceptability' demanded by constructivist rationalism (see below). While admitting that `no one has yet devised a means of keeping society together without traditional ethical principles', Born yet hopes that these can be replaced 'by means of the traditional method used in science'. He too fails to see that what lies between instinct and reason cannot be replaced by 'the traditional method used in science'."

"He felt that what is called “Copenhagen interpretation” should be called “Göttingen interpretation,” and was a bit hurt that he got the Nobel rather late."

"There is no reason why an extraphysical general principle is necessarily to be avoided, since such principles could conceivably serve as useful working hypotheses. For the history of scientific research is full of examples in which it was very fruitful indeed to assume that certain objects or elements might be real, long before any procedures were known which would permit them to be observed directly."

"The universe according to Bohm actually has two faces, or more precisely, two orders. One is the explicate order, corresponding to the physical world as we know it in day-to-day reality, the other a deeper, more fundamental order which Bohm calls the implicate order. The implicate order is the vast holomovement. We see only the surface of this movement as it presents or "explicates" itself from moment to moment in time and space. What we see in the world — the explicate order — is no more than the surface of the implicate order as it unfolds. Time and space are themselves the modes or forms of the unfolding process. They are like the screen on the video game. The displays on the screen may seem to interact directly with each other but, in fact, their interaction merely reflects what the game computer is doing. The rules which govern the operation of the computer are, of course, different from those that govern the behavior of the figures displayed on the screen. Moreover, like the implicate order of Bohm's model, the computer might be capable of many operations that in no way apparent upon examination of the game itself as it progresses on the screen."

"According to Bohm, the ground of the cosmos is not elementary particles but pure process, a flowing movement of the whole. Within this implicate order, Bohm believed, one could resolve the Cartesian split between mind and matter, or between brain and consciousness."

"Dave always arrives at the right conclusions, but his mathematics is terrible. I take it home and find all sorts of errors and then have to spend the night trying to develop the correct proof. But in the end, the result is always exactly the same as the one Dave saw directly."

"I can tell you one thing. David Bohm knows a lot more than just a little about physics."

"In the early 1950s, [...] there were two important advances in the interpretation of quantum mechanics, both made by the American physicist David Bohm. Just as there were, it seems, two Bohrs, there were apparently two Bohms: a 1951 Bohm and a 1952 Bohm."

"What is essential here is the presence of the spirit of dialogue, which is in short, the ability to hold many points of view in suspension, along with a primary interest in the creation of common meaning."

"A key difference between a dialogue and an ordinary discussion is that, within the latter people usually hold relatively fixed positions and argue in favor of their views as they try to convince others to change. At best this may produce agreement or compromise, but it does not give rise to anything creative."

"It is proposed that a form of free dialogue may well be one of the most effective ways of investigating the crisis which faces society, and indeed the whole of human nature and consciousness today. Moreover, it may turn out that such a form of free exchange of ideas and information is of fundamental relevance for transforming culture and freeing it of destructive misinformation, so that creativity can be liberated."

"Dialogue, as we are choosing to use the word, is a way of exploring the roots of the many crises that face humanity today. It enables inquiry into, and understanding of, the sorts of processes that fragment and interfere with real communication between individuals, nations, and even different parts of the same organization. In our modern culture men and women are able to interact with one another in many ways: they can sing, dance, or play together with little difficulty, but their ability to talk together about subjects that matter deeply to them seems invariably to lead to dispute, division, and often to violence. In our view this condition points to a deep and pervasive defect in the process of human thought."

"Communication can lead to the creation of something new only if people are able to freely listen to each other, without prejudice, and without trying to influence each other. Each has to be interested primarily in truth and coherence, so that he is ready to drop his old ideas and intentions, and be ready to go on to something different, when this is called for."

"We don't need the notion of an identity, of an all-important identity on to which we are going to hold, because that gets in the way of the need to change our reflexes. Once we identify with something, our reflexes are that way – it's very important, 'necessary'. And we will want to preserve that identity even thought it may involve ideas that are false."

"...we see a rainbow, but what we have is drops of rain and light – a process. Similarly, what we 'see' is a self; but what we actually have is a whole lot of thoughts going on in consciousness. Against the backdrop of consciousness, we are projecting a self, rather than a rainbow."

"The perception of truth is an actual act which changes things; it’s not merely that it is the truth about something which is different."

"There's nothing more ephemeral than thoughts; and yet thoughts can hold themselves by saying 'I must remain this way forever, with absolute necessity.' The point is to have the notion of a creative being, rather than of an identified being."

"...if you have found the words which express the way you are actually thinking, the body will be affected."

"...the attempt to deal with social problems by force is incoherent, because the problems all arise in thought. And violence will never solve the problem in thought."

"…when an insight is put into words, what is it that puts it into words? Is it thought or is it the insight? I want to suggest that the insight itself will be an insight into the words which express it properly."

"One of the most powerful thoughts people have is the thought of necessity. It is much more than a thought. The word 'necessary' means 'it cannot be otherwise', and the Latin root means 'don't yield'. It suggests the emotional-physical stance of resisting, holding. That's the other side of the reflex system: when you say 'it cannot be otherwise', in effect your'e saying: 'It has got to be this way. I have to keep it this way'. You have a hold. Something that is necessary is a very powerful force which you can't turn aside. You may say 'I have to turn it aside.' Thus we establish an order of necessity, saying 'this turns aside for that, and this for that.'"

"...thought is a very subtle set of reflexes which is potentially unlimited; you can add more and more and you can modify your reflexes. Suppose like a logician you say: 'All swans are white. This bird is a wan therefore this bird is white.' But then you modify this by saying, 'I've seen that some swans may not be white.' And so on. Even the whole logical process, once it's committed to memory, becomes a set of reflexes. There may be a perception of reason beyond the reflexes, but anything perceived becomes sooner or later a set of reflexes. And what's what I want to call 'thought' – which includes the emotion, the bodily state, the physical reaction and everything else."

"We started out saying the trouble is that the world is in chaos, but I think we end up by saying that thought is in chaos. That's each one of us. And that is the cause of the world's being in chaos. Then the chaos of the world comes back and adds to the chaos of thought."

"What I mean by 'thought' is the whole thing — thought, 'felt', the body, the whole society sharing thoughts — it's all one process. It is essential for me not to break that up, because it's all one process; somebody else's thought becomes my thought, and vice versa. Therefore it would be wrong and misleading to break it up into my thought, your thought, my feelings, these feelings, those feelings. I would say that thought makes what is often called in modern language a system. A system means a set of connected things or parts. But the way people commonly use the word nowadays it means something all of whose parts are mutually interdependent — not only for their mutual action, but for their meaning and for their existence. A corporation is organized as a system — it has this department, that department, that department... they don't have any meaning separately; they only can function together. And also the body is a system. Society is a system in some sense. And so on. Similarly, thought is a system. That system not only includes thought and feelings, but it includes the state of the body; it includes the whole of society — as thought is passing back and forth between people in a process by which thought evolved from ancient times. Thought has been constantly evolving and we can't say when that system began. But with the growth of civilization it has developed a great deal. It was probably very simple thought before civilization, and now it has become very complex and ramified and has much more incoherence than before. Now, I say that this system has a fault in it — a 'systematic fault'. It is not a fault here, there or here, but it is a fault that is all throughout the system. Can you picture that? It is everywhere and nowhere. You may say I see a problem here, so I will bring my thoughts to bear on this problem". But "my" thought is part of the system. It has the same fault as the fault I'm trying to look at, or a similar fault. Thought is constantly creating problems that way and then trying to solve them. But as it tries to solve them it makes it worse because it doesn’t notice that it's creating them, and the more it thinks, the more problems it creates."

"Culture is shared meaning. Suppose we were able to share meanings freely without a compulsive urge to impose our view or conform to those of others and without distortion and self-deception. Would this not constitute a real revolution in culture."
