Abstract
This was originally written and presented at the National Endowment for the Humanities Summer Seminar for College Teachers on Folk Psychology vs. Mental Simulation: How Minds Understand Minds, run by Robert Gordon at the University of Missouri - St. Louis, June-July 1999. It has been only lightly revised since, and should be considered a rough draft. Needless to say, the ideas herein owe a lot to what I learned at the seminar from Robert Gordon and the other participants, particularly Jim Garson. However, any errors are my responsibility alone
