Agnostics

"It seems that if one is working from the point of view of getting beauty in one's equations, and if one has really a sound insight, one is on a sure line of progress. If there is not complete agreement between the results of one's work and experiment, one should not allow oneself to be too discouraged, because the discrepancy may well be due to minor features that are not properly taken into account and that will get cleared up with further development of the theory."

"{\int _{-\infty }^{\infty }{\delta \left({x}\right){d{x}}}}=1 \delta \left({x}\right)=0 \text{ for } x\not= 0"

"... people have tried to establish analogies with systems in classical mechanics, such as vibrating strings or membranes... Such analogies have led to the name 'Wave Mechanics' being sometimes given to quantum mechanics. It is important to remember, however, that the superposition that occurs in quantum mechanics is of an essentially different nature from any occurring in the classical theory, as is shown by the fact that the quantum superposition principle demands indeterminacy in the results of observations in order to be capable of a sensible physical interpretation. The analogies are thus liable to be misleading."

"The nature of the relationships which the superposition principle requires to exist between the states of any system is of a kind that cannot be explained in terms of familiar physical concepts. One cannot in the classical sense picture a system being partly in each of two states and see the equivalence of this to the system being completely in some other state. There is an entirely new idea involved, to which one must get accustomed and in terms of which one must proceed to build up an exact mathematical theory, without having any detailed classical picture."

"... we cannot observe a small system with that amount of detail which classical theory supposes. The limitation in the power of observation puts a limitation on the number of data that can be assigned to a state... A state of a system may be defined as an undisturbed motion that is restricted by as many conditions or data as are theoretically possible without mutual interference or contradiction."

"The reader.. may argue that a very strange idea has been introduced — the possibility of a photon being partly in each of two states of polarization, or partly in each of two separate beams — but even with the help of this strange idea no satisfying picture of the fundamental single-photon processes has been given... it may be remarked that the main object of physical science is not the provision of pictures, but is the formulation of laws governing phenomena and the application of these laws to the discovery of new phenomena. If a picture exists, so much the better; but whether a picture exists or not is a matter of only secondary importance. In the case of atomic phenomena no picture can be expected to exist in the usual sense of the word 'picture', by which is meant a model functioning essentially on classical lines. One may, however, extend the meaning of the word 'picture' to include any way of looking at the fundamental laws which makes their self-consistency obvious. With this extension, one may gradually acquire a picture of atomic phenomena by becoming familiar with the laws of the quantum theory."

"We may define an object to be big when the disturbance accompanying our observation of it may be neglected, and small when the disturbance cannot be neglected... In order to give an absolute meaning to size, such as is required for any theory of the ultimate structure of matter, we have to assume that there is a limit to the fineness of our powers of observation and the smallness of the accompanying disturbance... If the object under observation is such that the unavoidable limiting disturbance is negligible, then the object is big in the absolute sense and we may apply classical mechanics to it. If, on the other hand, the limiting disturbance is not negligible, then the object is small in the absolute sense and we require a new theory for dealing with it."

"Classical mechanics has been developed continuously from the time of Newton and applied to an ever-widening range of dynamical systems, including the electromagnetic field in interaction with matter. The underlying ideas and the laws governing their application form a simple and elegant scheme, which one would be inclined to think could not be seriously modified without having all its attractive features spout. Nevertheless it has been found possible to set up a new scheme, called quantum mechanics, which is more suitable for the description of phenomena on the atomic scale and which is in some respects more elegant and satisfying than the classical scheme. This possibility is due to the changes which the new scheme involves being of a very profound character and not clashing with the features of the classical theory that make it so attractive, as a result of which all these features can be incorporated in the new scheme."

"I have the best of reasons for being an admirer of Werner Heisenberg. He and I were young research students at the same time, about the same age, working on the same problem. Heisenberg succeeded where I failed. There was a large mass of spectroscopic data accumulated at that time and Heisenberg found out the proper way of handling it. In doing so he started the golden age in theoretical physics, and for a few years after that it was easy for any second rate student to do first rate work."

"If you are receptive and humble, mathematics will lead you by the hand. Again and again, when I have been at a loss how to proceed, I have just had to wait until I have felt the mathematics led me by the hand. It has led me along an unexpected path, a path where new vistas open up, a path leading to new territory, where one can set up a base of operations, from which one can survey the surroundings and plan future progress."

"I was taught at school never to start a sentence without knowing the end of it."

"The aim of science is to make difficult things understandable in a simpler way; the aim of poetry is to state simple things in an incomprehensible way. The two are incompatible."

"The interpretation of quantum mechanics has been dealt with by many authors, and I do not want to discuss it here. I want to deal with more fundamental things."

"A good deal of my research work in physics has consisted in not setting out to solve some particular problems, but simply examining mathematical quantities of a kind that physicists use and trying to get them together in an interesting way regardless of any application that the work may have. It is simply a search for pretty mathematics. It may turn out later that the work does have an application. Then one has had good luck."

"God used beautiful mathematics in creating the world."

"It seems clear that the present quantum mechanics is not in its final form. Some further changes will be needed, just about as drastic as the changes made in passing from Bohr's orbit theory to quantum mechanics. Some day a new quantum mechanics, a relativistic one, will be discovered, in which we will not have these infinities occurring at all. It might very well be that the new quantum mechanics will have determinism in the way that Einstein wanted."

"My research work was based in pictures. I needed to visualise things and projective geometry was often most useful e.g. in figuring out how a particular quantity transforms under Lorentz transf[ormation]. When I came to publish the results I suppressed the projective geometry as the results could be expressed more concisely in analytic form."

"I went back to Cambridge at the beginning of October, 1925, and resumed my previous style of life, intense thinking about these problems during the week and relaxing on Sunday, going for a long walk in the country alone... It was during one of the Sunday walks in October, 1925, when I was thinking very much about this uv - vu, in spite of my intention to relax, that I thought about Poisson brackets. I remembered something which I had read up previously in advanced books of dynamics about these strange quantities, Poisson brackets, and from what I could remember, there seemed to be a close similarity between a Poisson bracket of two quantities, u and v, and the commutator uv - vu. The idea first came in a flash, I suppose, and provided of course some excitement, and then of course came the reaction "No, this is probably wrong." I did not remember very well the precise formula for a Poisson bracket, and only had some vague recollections. But there were exciting possibilities there, and I thought that I might be getting to some big new idea... it was a Sunday evening then and the libraries were all closed. I just had to wait impatiently through that night without knowing whether this idea was really any good or not, but still I think that my confidence gradually grew during the course of the night. The next morning I hurried along to one of the libraries as soon as it was open, and then I looked up Poisson brackets in Whittaker's Analytical Dynamics, and I found that they were just what I needed."

"I want to emphasize the necessity for a sound mathematical basis for any fundamental physical theory. Any philosophical ideas that one may have play only a subordinate role. Unless such ideas have a mathematical basis they will be ineffective."

"The underlying physical laws necessary for the mathematical theory of a large part of physics and the whole of chemistry are thus completely known, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble. It therefore becomes desirable that approximate practical methods of applying quantum mechanics should be developed, which can lead to an explanation of the main features of complex atomic systems without too much computation."

"If we are honest — and scientists have to be — we must admit that religion is a jumble of false assertions, with no basis in reality. The very idea of God is a product of the human imagination. It is quite understandable why primitive people, who were so much more exposed to the overpowering forces of nature than we are today, should have personified these forces in fear and trembling. But nowadays, when we understand so many natural processes, we have no need for such solutions. I can't for the life of me see how the postulate of an Almighty God helps us in any way. What I do see is that this assumption leads to such unproductive questions as why God allows so much misery and injustice, the exploitation of the poor by the rich and all the other horrors He might have prevented. If religion is still being taught, it is by no means because its ideas still convince us, but simply because some of us want to keep the lower classes quiet. Quiet people are much easier to govern than clamorous and dissatisfied ones. They are also much easier to exploit. Religion is a kind of opium that allows a nation to lull itself into wishful dreams and so forget the injustices that are being perpetrated against the people. Hence the close alliance between those two great political forces, the State and the Church. Both need the illusion that a kindly God rewards — in heaven if not on earth — all those who have not risen up against injustice, who have done their duty quietly and uncomplainingly. That is precisely why the honest assertion that God is a mere product of the human imagination is branded as the worst of all mortal sins."

"If there is no complete agreement between the results of one's work and the experiment, one should not allow oneself to be too discouraged."

"I don't suppose that applies so much to other physicists; I think it’s a peculiarity of myself that I like to play about with equations, just looking for beautiful mathematical relations which maybe don’t have any physical meaning at all. Sometimes they do."

"It was a good description to say that it was a game, a very interesting game one could play. Whenever one solved one of the little problems, one could write a paper about it. It was very easy in those days for any second-rate physicist to do first-rate work. There has not been such a glorious time since then."

"With my assumption... life need never end. There is no decisive argument for deciding between [certain] assumptions. I prefer the one that allows the possibility of endless life. One may hope that some day the question will be decided by direct observation."

"In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in the case of poetry, it's the exact opposite!"

"One possibility in this direction is to regard, classically, an electron as the end of a single Faraday line of force. The electric field in this picture from discrete Faraday lines of force, which are to be treated as physical things, like strings. One has then to develop a dynamics for such a string like structure, and quantize it.... In such a theory a bare electron would be inconceivable, since one cannot imagine the end of a piece of string without having the string."

"At the beginning of time the laws of Nature were probably very different from what they are now. Thus we should consider the laws of Nature as continually changing with the epoch, instead of as holding uniformly throughout space-time. This idea was first put forward by Milne, who worked it out on... assumptions... not very satisfying... we should expect them also to depend on position in space, in order to preserve the beautiful idea of the theory of relativity [that] there is fundamental similarity between space and time."

"Another equally true saying of Schumann is that, compared with Beethoven, Schubert is as a woman to a man. For it must be confessed that one's attitudes towards him is almost always that of sympathy, attraction, and love, rarely that of embarrassment or fear. Here and there only, as in the Rosamund B minor Entr'acte, or the Finale of the 10th symphony, does he compel his listeners with an irrestistible power; and yet how different is this compulsion from the strong, fierce, merciless coercion, with which Beethoven forces you along, and bows and bends you to his will."

"The distance in form, intention, mood and expression between Schubert's songs for voice and piano and those of, say, Adele is remarkably small."

"Most kings and priests have been despotic, and all religions have been riddled with superstition."

"Like a piece of litmus paper, he has always been quick to take the colour of his times."

"Mr. Aldous Huxley, who is perhaps one of those people who have to perpetrate thirty bad novels before producing a good one, has a certain natural — but little developed — aptitude for seriousness."

"You could always tell by his conversation which volume of the Encyclopedia Britannica he'd been reading. One day it would be Alps, Andes and Apennines, and the next it would be the Himalayas and the Hippocratic Oath."

"Huxley enjoyed the follies of the human mind even as he stoically stood out against them...Shock was one of the luxuries of the Twenties. But for Huxley, perhaps the most accomplished educator of his generation, to shock was to ensure the course of intellectual freedom."

"Aldous Huxley's spell was the old Arnold-Huxley spell of an education, disseminated with wit from above. It was imposed by his mastery of the art of conversation."

"European soldiers, traders, missionaries - later on ably assisted by its colonial ideologies and scholars - opened up the East to the influences of the West. But Huxley belonged to that small group of European thinkers and seekers who opened up the West to the influence of the East - a more arduous task and in the long run perhaps more important too. He did not seek this role, it was merely a bye-product of his search for truth. Huxley was one of the finest products of Europe - of a new Europe seeking its old roots, of a Europe no longer satisfied with mere technology and science and rationality but seeking a new dimension of the spirit, a Europe self-critical and in search. He was also a profound student of Europe's various traditions, religious, literary and artistic, and he discusses them with great knowledge, insights, authority and intimacy. In his hands, cultural Europe becomes alive. A critical discussion of Europe by such a sympathetic insider is meant to help, to fecundate; it can do no harm but will only help Europe in its spiritual rediscovery. In opening up to India and China, it would merely be opening up to an ancient tradition which was lost by her but preserved and developed in India and China."

"On the morning of November 22nd, a Friday, it became clear the gap between living and dying was closing. Realizing that Aldous [Huxley] might not survive the day, Laura [Huxley's wife] sent a telegram to his son, Matthew, urging him to come at once. At ten in the morning, an almost inaudible Aldous asked for paper and scribbled "If I go" and then some directions about his will. It was his first admission that he might die ...Around noon he asked for a pad of paper and scribbledLSD-try it intermuscular 100mmIn a letter circulated to Aldous's friends, Laura Huxley described what followed: 'You know very well the uneasiness in the medical mind about this drug. But no 'authority', not even an army of authorities, could have stopped me then. I went into Aldous's room with the vial of LSD and prepared a syringe. The doctor asked me if I wanted him to give the shot- maybe because he saw that my hands were trembling. His asking me that made me conscious of my hands, and I said, 'No, I must do this.'An hour later she gave Huxley a second 100mm. Then she began to talk, bending close to his ear, whispering, 'light and free you let go, darling; forward and up. You are going forward and up; you are going toward the light. Willingly and consciously you are going, willingly and consciously, and you are doing this beautifully — you are going toward the light — you are going toward a greater love ... You are going toward Maria's [Huxley's first wife, who had died many years earlier] love with my love. You are going toward a greater love than you have ever known. You are going toward the best, the greatest love, and it is easy, it is so easy, and you are doing it so beautifully.'All struggle ceased. The breathing became slower and slower and slower until, 'like a piece of music just finishing so gently in sempre piu piano, dolcamente,' at twenty past five in the afternoon, Aldous Huxley died."

"Above all, it is to my husband that I owe my deepest thanks. At times, when intensely absorbed by a new idea, I would enthusiastically jot it down in an English that was not very English. His harshest criticism then would be, "Stop a minute-your English is getting just a little too eccentric!" There was never criticism without advice; there was always that extraordinary feeling of good will which is constantly present in him and of which, on this occasion, he gave with particular abundance."

"[N]ow, after I have been alone these few days, and less bombarded by other people's feelings, the meaning of this last day becomes clearer and clearer to me and more and more important. Aldous was, I think (and certainly I am) appalled at the fact that what he wrote in ISLAND was not taken seriously. It was treated as a work of science fiction, when it was not fiction because each one of the ways of living he described in ISLAND was not a product of his fantasy, but something that had boon tried in one place or another and some of them in our own everyday life. If the way Aldous died were known, it might awaken people to the awareness that not only this, but many other facts described in ISLAND are possible here and now. Aldous' asking for moksha medicine while dying is a confirmation of his work, and as such is of importance not only to us, but to the world. It is true we will have some people saying that he was a drug addict all his life and that he ended as one, but it is history that Huxley's stop ignorance before ignoracne can stop Huxleys."

"Aldous smiled; he knew what one can see in a dirty dish when the doors of perception are cleansed."

"Aldous Huxley's Doors of Perception and Heaven and Hell as well as Alan Watts' The Joyous Cosmology spoke eloquently of the dimensions the psychedelics open up."

"Maria Huxley, Aldous Huxley's first wife, was a major influence on him and pushed Aldous to more deeply explore parapsychology and Indigenous rituals, largely through her own network of women."

"Alice in Wonderland fiend."

"I must comment briefly on Aldous Huxley's Island... Well I picked it up last night and just began rapidly leafing through it. What [her friend] sees in either of the Huxleys is quite beyond me...Running through what appears to be a completely confused and sort of nightmarish narrative, are stories of two women who were victims of breast cancer, including the deathbed scene of one of them!! Instead of being depressed, it made me so mad, I threw the book on the floor!"

"Aldous Huxley was uncannily prophetic, a more astute guide to the future than any other 20th- century novelist. Even his casual asides have a surprising relevance to our own times. During the first world war, after America's entry, he warned: "I dread the inevitable acceleration of American world domination which will be the result of it all...Europe will no longer be Europe." His sentiment is widely echoed today, though too late for us to do anything about it. The worst fate for a prophet is for his predictions to come true, when everyone resents him for being so clear-eyed."

"We cannot deny its brilliance, its learning, its honest attempt to answer the big human question."

"Medical science has made such tremendous progress that there is hardly a healthy human left."

"The only good that I can see in the demonstration of the truth of "Spiritualism" is to furnish an additional argument against suicide. Better live a crossing-sweeper than die and be made to talk twaddle by a "medium" hired at a guinea a séance."

"Ye shall know the truth and the truth shall make you mad."
