Rationality Quotes February 2013

Another monthly in­stal­l­ment of the ra­tio­nal­ity quotes thread. The usual rules ap­ply:

  • Please post all quotes sep­a­rately, so that they can be up­voted or down­voted sep­a­rately. (If they are strongly re­lated, re­ply to your own com­ments. If strongly or­dered, then go ahead and post them to­gether.)

  • Do not quote your­self.

  • Do not quote com­ments or posts from Less Wrong it­self or from Over­com­ing Bias.

  • No more than 5 quotes per per­son per monthly thread, please.
