Geisler’s Five Ways
Norman Geisler is a Thomist. His case for the existence of God is basically a simplified, clarified, and somewhat modified version of the case for God made by Thomas Aqinas in Summa Theologica. Geisler borrows the basic logical structure of the case for God made by Aquinas, as well as some of the specific sub-arguments of Aquinas.
The standard view of Aquinas has it that Aquinas presents Five Ways or five arguments for the existence of God. Geisler apparently accepts this standard view of Aquinas, and he is thus led to believe that his own case for God rests upon five arguments for the existence of God.
But the standard view of Aquinas is completely mistaken, and the Five Ways of Aquinas are NOT arguments for the existence of God. Similarly, Geisler mischaracterizes his own case for God as including five arguments for the existence of God. The truth of the matter, however, is that NONE of the five arguments presented by Geisler is an argument for the existence of God. Geisler literally does not know what he is doing.
