(From his short story "The Dream of a Ridiculous Man")
It was Fyodor Dostoevsky who said..
I am a ridiculous man. Now they call me a madman. That would be a promotion if it were not that I remain as ridiculous in their eyes as before. But now I do not resent it, they are all dear to me now, even when they laugh at me—and, indeed, it is just then that they are particularly dear to me. I could join in their laughter—not exactly at myself, but through affection for them, if I did not feel so sad as I look at them. Sad because they do not know the truth and I do know it. Oh, how hard it is to be the only one who knows the truth! But they won't understand that. No, they won't understand it.
