"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, 1897
This quote appears on the first page of Michael Lewis' new book, "The Big Short". It just was delivered to my office. It looks like a good read and is getting a lot of good press.
