Admiration is the daughter of ignorance.

It is the mark of an educated mind to be able to entertain a thought without accepting it.

Although our intellect always longs for clarity and certainty, our nature often finds uncertainty fascinating.

Power always thinks it has a great soul and vast views beyond the comprehension of the weak.

It takes a great man to be a good listener.

Obsession is the wellspring of genius and madness.

We sometimes congratulate ourselves at the moment of waking from a troubled dream; it may be so the moment after death.

The best revenge is to be unlike him who performed the injury.

Be curious, not judgmental.

Intelligence is a moral category.
