Better our hypotheses die for our errors than ourselves.

True ignorance is not the absence of knowledge, but the refusal to acquire it.

Ignorance is not a simple lack of knowledge but an active aversion to knowledge, the refusal to know, issuing from cowardice, pride, or laziness of mind.

There's a familiarity that sometimes shocks and annoys the hell out of me. People want a relationship with you that they haven't earned.

Israel deserves America's friendship in reality - not just in rhetoric.

Preaching and writing - it's the same. Whether I'm writing to speak or writing to be read in a book, it's the same thing.

Nature, always inartistic, takes pleasure in creating the impossible.

Men die the way they lived.

You can not stop you from being who you are.
