Once you have mathematical certainty there is nothing left to do or to understand. There will be nothing left but to bottle up your five senses and plunge into contemplation. While if you stick to consciousness, even though the same result is attained, you can at least flog yourself at times, and that will, at any rate, liven you up. Reactionary as it is, corporal punishment is better than nothing.

Autor: Fyodor Dostoevsky
