Said by Nietzsche Keith Gladysz

We must consider in this production of creative beings the indescribable malaise that they so often spread around themselves, when we evaluate the joy and ennoblement that humanity owes to their works. Their inability to dominate themselves, their jealousy, their ill-will and their uncertain characters mean that they are as often wrong-doers for humanity, where they would be its benefactors. In particular, the behavior of one genius to another is one of history's darkest pages. Veneration of genius has often been an unconscious form of devil worship. We should calculate how many men have corrupted their character and taste by frequenting geniuses.

We have perhaps more need of great men without works than great works for which such a heavy price has to be paid in terms of human souls. But at present we barely understand what a great man without works might be.
