Special thanks to Dr. David Shatz and Dr. T. M. Rudavksy for being my first Maimonides teachers and for inspiring my love for Maimonides' Guide. Thanks also to Chip Manekin for insights about Maimonides' sense of divine acts as natural acts at Guide 2.32 and for a useful discussion of points in Averroes' Tahafut, to James Wilberding for a helpful conversation about contemporary Aristotle scholarship on active intellect, and to Richard Taylor for his work on Averroes from which I continue to learn (I also borrowed my section 4 reminder to the reader to consult three relevant entries on creation terms in the Encyclopaedia of Islam from Taylor's work). My thanks also to the anonymous reviewer of the 2014 update for a number of useful suggestions.
