To the man who loves art for its own sake, it is frequently in its least important and lowliest manifestations that the keenest pleasure is to be derived.

I consider that a man's brain originally is like a little empty attic, and you have to stock it with such furniture as you choose.

For strange effects and extraordinary combinations we must go to life itself, which is always far more daring than any effort of the imagination.

Where there is no imagination there is no horror.

Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
