The trouble with psychology is that it doesn't take human nature into account.

It is not so much true that the world loves a lover as that the lover loves all the world.

It's living - a broad spectrum of living - that teaches you how to live, not philosophy. Philosophy teaches you how to think.

Many emotions go under the name of love, and almost any one of them will for a while divert the mind from the real, true, and perfect thing.

I try, and I think I succeed, in making my readers feel sorry for my psychopaths, because I do.

there must be a routine to life, a framework to hang life on. Routines were what kept you sane, gave you something to do at this moment and at that, definite places to go, positive things to do. Abandon it and that way madness lies.

To be a classic, a novel should be original.
