Darwin’s Trap

When Charles Darwin wrote “On the Origin of Species” in 1859, he employed an ingenious trick to persuade people of evolution. He linked evolution to natural selection, implying that natural selection was the mechanism of evolution. This was a clever trap because when something false (evolution) is linked with something true (natural selection), people are often fooled.

Understanding Bahnsen… Again

Our feedback this week once again comes from Peter who is still convinced that I have misrepresented the presuppositional method. Peter claims that (1) all forms of circular reasoning are fallacious and (2) that the presuppositional method as advanced by Bahnsen and Van Til does not involve any circular reasoning.

Bahnsen on Circular Reasoning

Our critic this week, Peter, is not a critic of Christianity. Rather, he has criticized my previous article in which I show the difference between vicious (arbitrary) circular reasoning and virtuous (rationally necessary, or “spiral”) circular reasoning. Peter has an unargued philosophical bias that all circular reasoning is wrong / fallacious, and that the presuppositional method used by Bahnsen and Van Til does not employ circular reasoning.

The Ultimate Standard

We previously covered the Münchhausen trilemma: an argument that knowledge is impossible because it can never be ultimately justified. Any (true) belief must be based on a good reason in order to be considered knowledge. But the reason is only good if it also is based on a good reason, which is based on a good reason and so on.
