Abstract Jeffrey Koperski claims in Zygon (2008) that critics of Intelligent Design engage in fallacious ad hominem attacks on ID proponents and that this is a “bad way” to engage them. I show that Koperski has made several errors in his evaluation of the ID critics. He does not distinguish legitimate, relevant ad hominem arguments from fallacious ad hominem attacks. He conflates (or equates) the logical use of valid with the colloquial use of valid. Moreover, Koperski doesn't take seriously the (...) legitimate concerns of the ID critics, and in doing so, commits the straw man fallacy. In the end, I show that no one disagrees with the criticism of improper use of fallacies as methods of evaluation. But what constitutes proper, relevant evaluation of the ID theorists and their motivation is a matter of dispute. And sometimes attacking a person as a method of evaluation is justified, and thus is not fallacious. The definition of ad hominem arguments as either a “good way” or a “bad way” rests on justification, which I argue ID opponents have. The basis for these good objections relies on the motivation many Christians have to share their faith with non-Christians, which they call the “great commission.”. (shrink)

The Monty Hall problem is consistently misunderstood. Mathematician Jeffrey Rosenthal argues in Monty Hall, Monty Fall, Monty Crawl” and Struck By Lightning that a proportionality principle can solve and explain the Monty Hall problem and its variants like Monty Fall and Monty Crawl better than the classic solution. Rosenthal’s Monty Fall example and solution are examined in detail. I show he has misidentified the crucial assumption in the Monty Hall problem, and his own Monty Fall problem is logically equivalent to (...) the original Monty Hall problem. I then present the Monty Fall* case where the probabilities for which door to pick post tease reveal are actually 50/50 using nothing more than Bayes’ Theorem and the standard rules of probability to prove the results—no proportionality principle is needed. The classic solution prevails as explanatorily more powerful. Finally, I show that Monty Crawl is also better explained and solved with the classic solution rather than with Rosenthal’s proportionality principle. (shrink)
