Quote: Carl Sagan

I just finished reading Carl Sagan's skeptical classic, The Demon-Haunted World and I found a lot of quotable material. Here's just one, in the context of the European witch hunts:

If we’re absolutely sure that our beliefs are right, and those of others wrong; that we are motivated by good, and others by evil; that the king of the universe speaks to us, and not to adherents of very different faiths, that it is wicked to challenge conventional doctrines or to ask searching questions; that our main job is to believe and obey – then the witch mania will recur in its infinite variations down to the time of the last man.
