I finally got around to watching Michael Lewis on Charlie Rose, and the interview ended with a Tolstoy quote from Lewis’ book that was too good not to post here:
"The most difficult subjects can be explained to the most slow-witted man if he has not formed any idea of them already; but the simplest thing cannot be made clear to the most intelligent man if he is firmly persuaded that he knows already, without a shadow of doubt, what is laid before him." –Leo Tolstoy
