I have been tortured with longing to believe ... and the yearning grows stronger the more cogent the intellectual difficulties stand in the way.

I wanted to discuss the suffering of humanity in general, but perhaps we'd better confine ourselves to the sufferings of children.

Inventors and geniuses have almost always been looked on as no better than fools at the beginning of their career, and very frequently at the end of it also.

Occasionally I was so much better that I could go out; but the streets used to put me in such a rage that I would lock myself up for days rather than go out, even if I were well enough to do so! I could not bear to see all those preoccupied, anxious-looking creatures continuously surging along the streets past me! Why are they always anxious? What is the meaning of their eternal care and worry? It is their wickedness, their perpetual detestable malice-that's what it is-they are all full of malice, malice!

I'm drunk but truthful.

To think too much is a disease.

A single day is sufficient for a man to discover what happiness is.
