Thoughts are ghosts of emotions.

One who learns to justify forgets to learn.

Idiots are of two kinds: those who try to be smart and those who think they are smart.

The intelligent have plans; the wise have principles.

A genius that survives is the real genius.

Intelligence seeks reasons behind things. Wisdom looks for things behind reasons.

An egoist is always intelligent, never wise.

Comparison is the most abused intellectual tool of all. We compare men and women, man and God, good and bad, equal and unequal, forgetting that this sin only results in a punishment so severe that we can't even trace it back to its origins. All we're left with in the end is ambiguity, uncertainty, lethargy and and Kafka!

Intelligence is to spot paradoxes. Wisdom is to live by them.
