"Once it's been proved to you that you're descended from an ape, it's no use pulling a face; just accept it. Once they've proved to you that a single droplet of your own fat must be dearer to you than a hundred thousand of your fellow human beings and consequently that all so-called virtues and duties are nothing but ravings and prejudices, then accept that too, because there's nothing to be done."

“Dreams, as we all know, are very queer things: some parts are presented with appalling vividness, with details worked up with the elaborate finish of jewellery, while others one gallops through, as it were, without noticing them at all, as, for instance, through space and time. Dreams seem to be spurred on not by reason but by desire, not by the head but by the heart, and yet what complicated tricks my reason has played sometimes in dreams, what utterly incomprehensible things happen to it!”

“What terrible tragedies realism inflicts on people.'”

“Fathers and teachers, I ponder, "What is hell?" I maintain that it is the suffering of being unable to love.”

“All became so jealous of the rights of their own personality that they did their very utmost to curtail and destroy them in others, and made that the chief thing in their lives. Slavery followed, even voluntary slavery; the weak eagerly submitted to the strong, on condition that the latter aided them to subdue the still weaker. Then there were saints who came to these people, weeping, and talked to them of their pride, of their loss of harmony and due proportion, of their loss of shame. They were laughed at or pelted with stones.”

“To study the meaning of man and of life — I am making significant progress here. I have faith in myself. Man is a mystery: if you spend your entire life trying to puzzle it out, then do not say that you have wasted your time. I occupy myself with this mystery, because I want to be a man.”

“It wasn't the New World that mattered … Columbus died almost without seeing it; and not really knowing what he had discovered. It's life that matters, nothing but life — the process of discovering, the everlasting and perpetual process, not the discovery itself, at all. But what's the use of talking! I suspect that all I'm saying now is so like the usual commonplaces that I shall certainly be taken for a lower-form schoolboy sending in his essay on "sunrise", or they'll say perhaps that I had something to say, but that I did not know how to "explain" it. But I'll add, that there is something at the bottom of every new human thought, every thought of genius, or even every earnest thought that springs up in any brain, which can never be communicated to others, even if one were to write volumes about it and were explaining one's idea for thirty-five years; there's something left which cannot be induced to emerge from your brain, and remains with you forever; and with it you will die, without communicating to anyone perhaps the most important of your ideas. But if I too have failed to convey all that has been tormenting me for the last six months, it will, anyway, be understood that I have paid very dearly for attaining my present "last conviction." This is what I felt necessary, for certain objects of my own, to put forward in my "Explanation". However, I will continue.”
