I meant to get us to game theory today, to talk about it with respect to the idea of other minds.  So, based on the 70% contest from the previous class (the winning number would have been 20.8)  we started discussing polls and Keynesian Beauty Contests.  My theory that people thought their candidate would lose was exploded (at least in the classroom).  Discussion of eternity in Portrait of the Artist as a Young Man, and then of the meaning of its title.
