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.
Saying that a great genius is mad, while at the same time recognizing his artistic worth, is like saying that he had rheumatism or suffered from diabetes. Madness, in fact, is a medical term that can claim no more notice from the objective critic than he grants the charge of heresy raised by the theologian, or the charge of immorality raised by the police.
A man would still do something out of sheer perversity - he would create destruction and chaos - just to gain his point...and if all this could in turn be analyzed and prevented by predicting that it would occur, then man would deliberately go mad to prove his point.
