One can purchase, via Amazon.com, Richard M. Gale and Alexander R. Pruss, The Existence of God (Ashgate Publishing Limited, 2003) for a mere $332.50. Of course, that is significantly less than the $350.00 list price and the $563.53 another seller is asking for. Moreover, the book is in hardcover, with 550 pages therein protected.
This is certainly a bargain, at least when compared with the $4,562 I took note of this past January 4 in my “Averroes’ Middle Commentary on Aristotle’s Poetics is Available.”
