The Fallibility of First Principles, by Gunther Laird (gunther.laird@gmail.com)
The late Norman Geisler was one of the most popular proponents of Evangelical Christianity, wedding Calvinistic argumentation with technical concepts drawn from the Catholic philosopher Thomas Aquinas.[1] His son David Geisler continues his work, and recently contacted John W. Loftus with a syllogism for God’s existence Norman had made in the Baker Encyclopedia of Christian Apologetics. David asked my editor if he had “any atheistic friends that would be willing to critique this more comprehensive argument for God’s existence and explain what’s wrong with it,” and I was one such friend, so John contacted me.
What follows is a brief critique of the entry “First Principles” in the Encyclopedia, which David copied verbatim in his email to John. The entry is quite substantive, as Norman Geisler provided very detailed descriptions of a variety of first principles, such as the Principle of Noncontradiction, the Principle of Causality, and the Principle of Contingency, and explains why they cannot be coherently denied under any circumstances.
