Rationality Quotes—July 2009

(Last month’s started a lit­tle late, I thought I’d bring it back to its origi­nal sched­ule.)

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 (or down) sep­a­rately) un­less they are strongly re­lated/​or­dered.

  • Do not quote your­self (or your sock­pup­pets).

  • Do not quote com­ments/​posts on LW/​OB—if we do this, there should be a sep­a­rate thread for it.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.
