The number of different aspects that the face of a man has assumed may be taken almost as a physiognomical measure of his … genius. - Otto Weininger

So far as one understands a man, one is that man. The man of genius takes his place in the above argument as 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.

The highest expression of all morality is: Be!

In men of genius, sterile years precede productive years, these again to be followed by sterility, the barren periods being marked by psychological self-depreciation, by the feeling that they are less than other men; times in which the remembrance of the creative periods is a torment, and when they envy those who go about undisturbed by such penalties. Just as his moments of ecstasy are more poignant, so are the periods of depression of a man of genius more intense than those of other men.
