“A stone is heavy and the sand is weighty; but a fool’s wrath is heavier than them both.”

“Those who meet Jesus always experience either joy or its opposites, either foretastes of Heaven or foretastes of Hell. Not everyone who meets Jesus is pleased, and not everyone is happy, but everyone is shocked.”

“True knowledge exists in knowing that you know nothing.”

“I think I exist, therefore I exist. I think.”

“I have been accused of a habit of changing my opinions. I am not myself in any degree ashamed of having changed my opinions. What physicist who was already active in 1900 would dream of boasting that his opinions had not changed during the last half century? In science men change their opinions when new knowledge becomes available; but philosophy in the minds of many is assimilated rather to theology than to science. The kind of philosophy that I value and have endeavoured to pursue is scientific, in the sense that there is some definite knowledge to be obtained and that new discoveries can make the admission of former error inevitable to any candid mind. For what I have said, whether early or late, I do not claim the kind of truth which theologians claim for their creeds. I claim only, at best, that the opinion expressed was a sensible one to hold at the time when it was expressed. I should be much surprised if subsequent research did not show that it needed to be modified. I hope, therefore, that whoever uses this dictionary will not suppose the remarks which it quotes to be intended as pontifical pronouncements, but only as the best I could do at the time towards the promotion of clear and accurate thinking. Clarity, above all, has been my aim.”

“If we are merely matter intricately assembled, is this really demeaning? If there’s nothing here but atoms, does that make us less or does that make matter more?”

“Every life is different because you passed this way and touched history.”

“You know, bicycling isn’t just a matter of balance,” I said. “it’s a matter of faith. You can keep upright only by moving forward. You have to have your eyes on the goal, not the ground. I’m going to call that the Bicyclist’s Philosophy of Life.”

“All men have their frailties; and whoever looks for a friend without imperfections, will never find what he seeks.”

“One must reach out and try to grasp this astonishing finesse, that the value of lif cannot be estimated.”

“Never say no to now”

“Ignore a person kill the person.”

“According to the Buddha’s teaching the beginning of the life-stream of living beings is unthinkable. THe believer in the creation of life by God may be astonished at this reply. But if you were to ask him ‘What is the beginning of God?’ he would answer without hesitation ‘God has no beginning’, and he is not astonished at his own reply.”

“Many scientists have tried to make determinism and complementarity the basis of conclusions that seem to me weak and dangerous; for instance, they have used Heisenberg’s uncertainty principle to bolster up human free will, though his principle, which applies exclusively to the behavior of electrons and is the direct result of microphysical measurement techniques, has nothing to do with human freedom of choice. It is far safer and wiser that the physicist remain on the solid ground of theoretical physics itself and eschew the shifting sands of philosophic extrapolations.”
