“Genius is always accompanied by enthusiasm.”

“The secret of genius is to carry the spirit of the child into old age, which means never losing your enthusiasm.”

“Because handsomeness is always accompanied by vanity.And I suppose ugliness is accompanied by a wealth of virtues?”

“Nothing is as contagious as enthusiasm. It is the real allegory of the myth of Orpheus; it moves stones, and charms brutes. It is the genius of sincerity, and truth accomplishes no victories without it.”

“An enthusiasm for Poe is the mark of a decidedly primitive stage of reflection. Baudelaire thought him a profound philosopher... Poe was much the greater charlatan of the two, as well as the greater genius.”

“I’ve always been suspicious of the assumption that great intelligence would be an unqualified benefit— that the madness that so often accompanies it can be cavalierly dismissed. So I asked the question: Suppose there were an entire subpopulation of extreme geniuses, well beyond anything that would occur naturally. What would that really look like?”
