The man of genius is he who understands incomparably more other beings than the average man. Goethe is said to have said of himself that there was no vice or crime of which he could not trace the tendency in himself, and that at some period of his life he could not have understood fully. The genius, therefore, is a more complicated, more richly endowed, more varied man; and a man is the closer to being a genius the more men he has in his personality, and the more really and strongly he has these others within him. If comprehension of those about him only flickers in him like a poor candle, then he is unable, like the great poet, to kindle a mighty flame in his heroes, to give distinction and character to his creations. The ideal of an artistic genius is to live in all men, to lose himself in all men, to reveal himself in multitudes; and so also the aim of the philosopher is to discover all others in himself, to fuse them into a unit which is his own unit.
