Doubt … is an illness that comes from knowledge and leads to madness.

What better occupation, really, than to spend the evening at the fireside with a book, with the wind beating on the windows and the lamp burning bright...Haven't you ever happened to come across in a book some vague notion that you've had, some obscure idea that returns from afar and that seems to express completely your most subtle feelings?

Judge the goodness of a book by the energy of the punches it has given you. I believe the greatest characteristic of genius, is, above all, force.

As humanity perfects itself, man becomes degraded. When everything is reduced to the mere counter-balancing of economic interests, what room will there be for virtue? When Nature has been so subjugated that she has lost all her original forms, where will that leave the plastic arts? And so on. In the mean time, things are going to get very murky.

Success as I see it is a result, not a goal.

[T]he truth is that fullness of soul can sometimes overflow in utter vapidity of language, for none of us can ever express the exact measure of his needs or his thoughts or his sorrows; and human speech is like a cracked kettle on which we tap crude rhythms for bears to dance to, while we long to make music that will melt the stars.

Stupidity lies in wanting to draw conclusions.
