"Whereas non-scientific (and potentially dangerous) thinking starts with a premise and then looks for things that support it, scientific thinking constantly tries to disprove itself. That alone makes all the difference in the world."

Previous Quote

Pride is the recognition of the fact that you are your own highest value and, like all of man's values, it has to be earned-that of any achievements open to you, the one that makes all others possible is the creation of your own character-that your character, your actions, your desires, your emotions are the products of the premises held by your mind.

— John Galt
