“The present is the only things that has no end.”

“If a man never contradicts himself, the reason must be that he virtually never says anything at all.”

“Our creed [atheism] is indeed a queer creed. You others, Christians (and similar people), consider our ethics much inferior, indeed abominable. There is that little difference. We adhere to ours in practice, you don't.”

“Science cannot tell us a word about why music delights us, of why and how an old song can move us to tears.”

“If we were bees, ants, or Lacedaemonian warriors, to whom personal fear does not exist and cowardice is the most shameful thing in the world, warring would go on forever. But luckily we are only men — and cowards.”

“The stages of human development are to strive for:
(1) Besitz [Possession]
(2) Wissen [Knowledge]
(3) Können [Ability]
(4) Sein”

“The material world has only been constructed at the price of taking the self, that is, mind, out of it, removing it; mind is not part of it…”

“How would we express in terms of the statistical theory the marvelous faculty of a living organism, by which it delays the decay into thermodynamical equilibrium (death)?… the device by which an organism maintains itself stationary at a fairly high level of orderliness… really consists in continually sucking orderliness from its environment.”

“We must therefore not be discouraged by the difficulty of interpreting life by the ordinary laws of physics. For that is just what is to be expected from the knowledge we have gained of the structure of living matter. We must also be prepared to find a new type of physical law prevailing in it. Or are we to term it a non-physical, not to say a super-physical, law?”

“If I try to hold on the currently predominant view and derive the unity of my self, … I find myself with an impenetrable thicket of questions. … Why is it precisely at this intermediate level in the hierarchy of successively superimposed unities (cell, organ, human body, state)—why, I ask, it is precisely at the level of my body that unitary self-consciousness comes into the picture, whereas the cell and the organ do not as yet possess it and the state possesses it no longer?”

“The unphilosophical and philosophical attitudes can be very sharply distinguished (with scarcely any intermediate forms) by the fact that the first accepts everything that happens as regards its general form, and finds occasion for surprise only in that special content by which something that happens here today differs from what happened there yesterday; whereas for the second, it is precisely the common features of all experience, such as characterise everything we encounter, which are the primary and most profound occasion for astonishment.”

“There is no kind of framework within which we can find consciousness in the plural; this is simply something we construct because of the temporal plurality of individuals, but it is a false construction… The only solution to this conflict insofar as any is available to us at all lies in the ancient wisdom of the Upanishad.”

“The "Schrödinger equation", equation (3') in "Quantisierung als Eigenwertproblem, Vierte Mitteilung", Annalen der Physik (1926)”

“We have just introduced the term gene for the hypothetical material carrier of a definite hereditary feature…”

“Vedanta teaches that consciousness is singular, all happenings are played out in one universal consciousness and there is no multiplicity of selves.”

“It seems plain and self-evident, yet it needs to be said: the isolated knowledge obtained by a group of specialists in a narrow field has in itself no value whatsoever, but only in its synthesis with all the rest of knowledge and only inasmuch as it really contributes in this synthesis toward answering the demand, "Who are we?"”

“In particular, and most importantly, this is the reason why the scientific worldview contains of itself no ethical values, no esthetical values, not a word about our own ultimate scope or destination, and no God, if you please. Whence came I and whither go I?”

“You may ask — you are bound to ask me now: What, then, is in your opinion the value of natural science? I answer: Its scope, aim and value is the same as that of any other branch of human knowledge. Nay, none of them alone, only the union of all of them, has any scope or value at all, and that is simply enough described: it is to obey the command of the Delphic deity: gnothi seauton… get to know yourself!”

“The laws of physics and chemistry are statistical throughout.”

“I consider it extremely doubtful whether the happiness of the human race has been enhanced by the technical and industrial developments that followed in the wake of rapidly progressing natural science.”

“Our mind, by virtue of a certain finite, limited capability, is by no means capable of putting a question to Nature that permits a continuous series of answers. The observations, the individual results of measurements, are the answers of Nature to our discontinuous questioning.”

“The spread, both in and width and depth, of the multifarious branches of knowledge by during the last hundred odd years has confronted us with a queer dilemma. We feel clearly that we are only now beginning to acquire reliable material for welding together the sum total of all that is known into a whole; but, on the other hand, it has become next to impossible for a single mind fully to command more than a small specialized portion of it. I can see no other escape from this dilemma (lest our true who aim be lost for ever) than that some of us should venture to embark on a synthesis of facts and theories, albeit with second-hand and incomplete knowledge of some of them -and at the risk of making fools of ourselves.”

“Matter and energy seem granular in structure, and so does "life", but not so mind.”

“In Darwin's theory, you just have to substitute 'mutations' for his 'slight accidental variations' (just as quantum theory substitutes 'quantum jump' for 'continuous transfer of energy'). In all other respects little change was necessary in Darwin's theory…”

“Not one word is said here of acausality, wave mechanics, indeterminacy relations, complementarity, … etc. Why doesn’t he talk about what he knows instead of trespassing on the professional philosopher’s preserves? Ne sutor supra crepidam. On this I can cheerfully justify myself: because I do not think that these things have as much connection as is currently supposed with a philosophical view of the world.”

“The sensation of colour cannot be accounted for by the physicist's objective picture of light-waves.”

“I insist upon the view that 'all is waves.”

“The task is, not so much to see what no one has yet seen; but to think what nobody has yet thought, about that which everybody sees.”

“If one has left this entire system to itself for an hour, one would say that the cat still lives if meanwhile no atom has decayed. The psi-function of the entire system would express this by having in it the living and dead cat (pardon the expression) mixed or smeared out in equal parts.”
