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", and it is precisely the reference to "God" in the conclusion of his first argument that makes that argument logically invalid … [Read more...]

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 A … [Read more...]

Geisler’s First Argument

Norman Geisler's case for God appears to consist of five arguments for the existence of God.Here is my critique of the opening paragraph of Geisler's case, and my critique of his first argument for the existence of God:======================NOTE: I forgot that my plan was to put my posts on cases for God here at The Secular Oupost, and put my posts that are more specifically about Jesus and Christianity over on my own blog site.  So, I have moved my post about Geisler's first … [Read more...]

Cases for God

I'm thinking about which cases for the existence of God to focus in on, for my evaluation of Christianity.  Right now, I'm thinking about examining the cases of four well-known Christian apologists:Norman Geisler William Craig Peter Kreeft Richard SwinburneI just realized that two of these philosophers are Thomists, and two are not Thomists.Geisler is a conservative Evangelical Christian, but his favorite argument for God is a Thomist cosmological argument, and his concept of … [Read more...]

T … [Read more...]

Jerry Coyne Criticizes A.C. Grayling’s Handling of God Arguments, But Coyne Gets It Wrong Himself

Jerry Coyne is a Harvard-educated, brilliant professor of biology who is an expert on biological evolution. His book, Why Evolution Is True, is a "must-read" for anyone interested in, well, why evolution is true.He also likes to write about topics outside of his area of expertise, including the philosophy of religion. As I've explained before, non-experts have the right to write about topics outside their area of expertise, but they owe it to themselves and their readers to make sure they k … [Read more...]

I Don’t Care

Thomas Aquinas pulled a classic BAIT-AND-SWITCH move in Summa Theologica: “Therefore it is necessary to arrive at a first mover, moved by no other; and this everyone understands to be God.”“Therefore it is necessary to admit a first efficient cause, to which everyone gives the name of God.” “Therefore we cannot but admit the existence of some being having of itself its own necessity, and not receiving it from another, but rather causing in others their necessity. This all men speak of … [Read more...]

Weighing Theistic Evidence Against Naturalistic Evidence

In the next-to-last paragraph of his book, C.S. Lewis' Dangerous Idea: In Defense of the Argument from Reason, Victor Reppert makes a very interesting statement: However, I contend that the arguments from reason do provide some substantial reasons for preferring theism to naturalism. The "problem of reason" is a huge problem for reason, as serious or, I would say, more serious, than the problem of evil is for theists. (emphasis mine) I think this is a very interesting statement for two r … [Read more...]
