philosophy

The only true wisdom is in knowing you know nothing.

Science is a way of thinking much more than it is a body of knowledge.

Act as if what you do makes a difference. It does.

Life must be understood backward. But it must be lived forward.

Wonder is the beginning of wisdom.

The unexamined life is not worth living.

Knowing yourself is the beginning of all wisdom.

Don't explain your philosophy. Embody it.

He who fears death will never do anything worthy of a man who is alive.
