“Imagination is cheap as long as you don’t have to worry about the details.”

“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.”

“Freedom is an absolute state, there is no such thing as being half-free.”

“Not only are there meaningless questions, but many of the problems with which the human intellect has tortured itself turn out to be only ‘pseudo problems,’ because they can be formulated only in terms of questions which are meaningless. Many of the traditional problems of philosophy, of religion, or of ethics, are of this character. Consider, for example, the problem of the freedom of the will. You maintain that you are free to take either the right- or the left-hand fork in the road. I defy you to set up a single objective criterion by which you can prove after you have made the turn that you might have made the other. The problem has no meaning in the sphere of objective activity; it only relates to my personal subjective feelings while making the decision.”

“Disobedience is the true foundation of liberty.”

“We may not yet know the right way to go, but we should at least stop going in the wrong direction.”

“To be a god can ultimately become boring and degrading. There’d be reason enough for the invention of free will! A god might wish to escape into sleep and be alive only in the unconscious projections of his dream-creatures.”

“Were these boys in their right minds? Here were two boys with good intellect, one eighteen and one nineteen. They had all the prospects that life could hold out for any of the young; one a graduate of Chicago and another of Ann Arbor; one who had passed his examination for the Harvard Law School and was about to take a trip in Europe,–another who had passed at Ann Arbor, the youngest in his class, with three thousand dollars in the bank. Boys who never knew what it was to want a dollar; boys who could reach any position that was to boys of that kind to reach; boys of distinguished and honorable families, families of wealth and position, with all the world before them. And they gave it all up for nothing, for nothing! They took a little companion of one of them, on a crowded street, and killed him, for nothing, and sacrificed everything that could be of value in human life upon the crazy scheme of a couple of immature lads.Now, your Honor, you have been a boy; I have been a boy. And we have known other boys. The best way to understand somebody else is to put yourself in his place.Is it within the realm of your imagination that a boy who was right, with all the prospects of life before him, who could choose what he wanted, without the slightest reason in the world would lure a young companion to his death, and take his place in the shadow of the gallows?…No one who has the process of reasoning could doubt that a boy who would do that is not right.How insane they are I care not, whether medically or legally. They did not reason; they could not reason; they committed the most foolish, most unprovoked, most purposeless, most causeless act that any two boys ever committed, and they put themselves where the rope is dangling above their heads….Why did they kill little Bobby Franks?Not for money, not for spite; not for hate. They killed him as they might kill a spider or a fly, for the experience. They killed him because they were made that way. Because somewhere in the infinite processes that go to the making up of the boy or the man something slipped, and those unfortunate lads sit here hated, despised, outcasts, with the community shouting for their blood.. . . I know, Your Honor, that every atom of life in all this universe is bound up together. I know that a pebble cannot be thrown into the ocean without disturbing every drop of water in the sea. I know that every life is inextricably mixed and woven with every other life. I know that every influence, conscious and unconscious, acts and reacts on every living organism, and that no one can fix the blame. I know that all life is a series of infinite chances, which sometimes result one way and sometimes another. I have not the infinite wisdom that can fathom it, neither has any other human brain”

“Every instinct that is found in any man is in all men. The strength of the emotion may not be so overpowering, the barriers against possession not so insurmountable, the urge to accomplish the desire less keen. With some, inhibitions and urges may be neutralized by other tendencies. But with every being the primal emotions are there. All men have an emotion to kill; when they strongly dislike some one they involuntarily wish he was dead. I have never killed any one, but I have read some obituary notices with great satisfaction.”
