Immanuel Kant

Metaphysics is a dark ocean without shores or lighthouse, strewn with many a philosophic wreck.

So act that your principle of action might safely be made a law for the whole world.

Experience without theory is blind, but theory without experience is mere intellectual play.

A myth is a lie that conceals or reveals a truth. But if it reveals even a strand of history or truth, that's what gets my adrenaline going.

I really think the most important thing I do is to protect the dignity and the integrity of the Office of the Surgeon General.

If I hear a lie in my life with my children, with my wife, my work, my audiences, I want to annihilate myself, vaporize myself and wipe myself off the face of the earth.
