If a man sets out to hate all the miserable creatures he meets, he will not have much energy left for anything else; whereas he can despise them, one and all, with the greatest ease.
In order to increase his pleasures, man has intentionally added to the number and pressure of his needs, which in their original state were not much more difficult to satisfy than those of the brute. Hence luxury in all its forms; delicate food, the use of tobacco and opium, spirituous liquors, fine clothes, and the thousand and one things that he considers necessary to his existence.
It is most important to allow the brain the full measure of sleep which is required to restore it; for sleep is to a man's whole nature what winding up is to a clock.
I have not yet spoken my last word about women. I believe that if a woman succeeds in withdrawing from the mass, or rather raising herself from above the mass, she grows ceaselessly and more than a man.
If the world were a paradise of luxury and ease, a land flowing with milk and honey, where every Jack obtained his Jill at once and without any difficulty, men would either die of boredom or hang themselves; or there would be wars, massacres, and murders; so that in the end mankind would inflict more suffering on itself than it has now to accept at the hands of Nature.

Do not shorten the morning by getting up late, or waste it in unworthy occupations or in talk; look upon it as the quintessence of life, as to a certain extent sacred. Evening is like old age: we are languid, talkative, silly. Each day is a little life: every waking and rising a little birth, every fresh morning a little youth, every going to rest and sleep a little death.
There is in the world only the choice between loneliness and vulgarity. All young people should be taught now to put up with loneliness ... because the less man is compelled to come into contact with others, the better off he is.
(Politeness is) a tacit agreement that people's miserable defects, whether moral or intellectual, shall on either side be ignored and not be made the subject of reproach.
Memory works like the collection glass in the Camera obscura: it gathers everything together and therewith produces a far more beautiful picture than was present originally.
