I am deeply grateful for the invaluable comments, suggestions, and corrections I received from historian Richard Carrier, philosopher Tom Clark, and the following members of the Internet discussion list avoid-L that tirelessly provides me with feedback on my writing: Martin Bier, Lawrence Crowell, Keith Douglas, Yonatan Fishman, John Mazetier, Don McGee, Brent Meeker, Kerry Regier, Anne O'Reilly, Christopher Savage, and Bob Zannelli. I would also like to thank the staff of the public library in Louisville, Colorado, for the efficiency with which they provide me with books from other libraries throughout the state.
