If you wish to obtain a great name or to found an establishment, be completely mad; but be sure that your madness corresponds with the turn and temper of your age.
Madness is the first step towards unselfishness. Be mad and tell us what is behind the veil of "sanity". The purpose of life is to bring us closer to those secrets, and madness is the only means.
When we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were but we shall understand the whole thing. The same phenomena will remain but with a new meaning.
