Carl Sagan Quotes, Attitude Quotes, Thinking Quotes

That kind of skeptical, questioning, "don't accept what authority tells you" attitude of science - is also nearly identical to the attitude of mind necessary for a functioning democracy.

Like some ghastly cannibal cult, we subsist on the dead bodies of our ancestors and distant relatives. - Dr. Carl Sagan
