Leibniz, Gottfried Wilhelm (1646-1716): Although the whole of this life were said to be nothing but a dream and the physical world nothing but a phantasm, I should call this dream or phantasm real enough, if, using reason well, we were never deceived by it.

In J. R. Newman (ed.), The World of Mathematics, New York: Simon and Schuster, 1956.

A monthly thread for posting any interesting rationality-related quotes you've seen recently on the Internet, or had stored in your quotesfile for ages.

  • Please post all quotes separately (so that they can be voted up/down separately) unless they are strongly related/ordered.
  • Do not quote yourself.
  • Do not quote comments/posts on LW/OB - if we do this, there should be a separate thread for it.
  • No more than 5 quotes per person per monthly thread, please.
