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 God as ipsum esse subsistens, Thomas deduces certain other properties which must belong to God [i.e. in order to prove that "God", in the ordinary sense of the word, exists].  T … [Read more...]

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 tiny piece of that very long and complicated argument.The Five Ways passage presents arguments for these five metaphysical claims:(MC1) There exists a UFC being.   … [Read more...]

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 are versions of Aquinas' Five Ways:A word about the organization of the arguments.  We have organized them into two basic groups: those wh … [Read more...]

I Don’t Care – Part 2

OK. Maybe I care just a little bit.I summarized my complaint against Aquinas' Five Ways this way (in response to a comment from Jeff Lowder):I'm just pointing out that (a) NONE of the Five Ways is an argument for the existence of God as it stands (in the section called "Whether God Exists?"), and (b) in order to make use of any of the Five Ways as an argument for the existence of God, there is a serious amount of intellectual effort required to fill the logical gap that is located in the … [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...]

William Lane Craig: 36 Years of Equivocation – Part 2

One reason why it should be OBVIOUS that Craig's Kalam Cosmological Argument (hereafter: KCA) involves the fallacy of equivocation, is that Aquinas commits a very similar fallacy of equivocation in his cosmological arguments for God.Every (or almost every) introduction to philosophy of religion course includes at least a brief examination of Aquinas's Five Ways or Five Arguments for God.  So,  almost every philosophy student who has taken an introduction to philosophy of religion course has b … [Read more...]
