Geisler’s Five Ways – Part 2: How Many Arguments for God?

In Chapter  2 of When Skeptics Ask (hereafter: WSA), Norman Geisler appears to present five different arguments for the existence of God.  However, there are some significant problems with this characterization of Geisler’s case for God.   NONE of the five arguments end with the conclusion that “God exists”.  In fact, only his first argument even mentions the word “God”, Geisler’s Five Ways – Part 2: How Many Arguments for God?

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 Geisler’s Five Ways

I Don’t Care – Part 6

Aquinas is often thought of as a rigourously logical and systematic thinker.  This is only half-true.  There is a good deal of vaguness, ambiguity, and illogical thinking in his book Summa Theologica, as far as I can see. Here is a cautionary note from a philosopher who is an expert on Aquinas: From the concept of I Don’t Care – Part 6

I Don’t Care – Part 5

The famous Five Ways passage by Aquinas in Summa Theologica does not contain five arguments for the existence of God. Rather, it contains ZERO arguments for the existence of God.  There is actually only one argument for the existence of God in the Summa Theologica, and the reasoning in the Five Ways passage only represents a I Don’t Care – Part 5

I Don’t Care – Part 4

I have previously argued that, contrary to popular opinion, there are ZERO arguments for the existence of God in the famous Five Ways passage by Aquinas in Summa Theologica (Part I, Question 2, Article 3: Whether God Exists?). Now I’m getting into what I do care about, namely the ACTUAL argument(s) that Aquinas gives to prove the I Don’t Care – Part 4

I Don’t Care – Part 3

According to the Christian philosopher Peter Kreeft, and many others, Aquinas gives five different arguments for the existence of God.  In the Handbook of Christian Apologetics (IVP, 1994; hereafter: HCA) by Peter Kreeft and Ronald Tacelli, there is a chapter that lays out twenty different arguments for the existence of God, and the first five arguments I Don’t Care – Part 3
