 In the same issue, Keith M. Parsons, the then editor of "Philo", presented some arguments against Reppert's conclusions in the course of a review of Thomas Nagel's "The Last Word", so in 2000 Reppert wrote a "Reply to Parsons and Lippard", to which Parsons responded by writing the first full-dress attempt to refute Reppert's argument.Reppert's reply to Parsons was the paper "Causal Closure, Mechanism, and Rational Inference", which, since he felt it was time that more Christian philosophers were familiarized with the argument and related issues, appeared in 2001 in "Philosophia Christi".In 2003 "Philosophia Christi" featured a "Symposium on the Argument from Reason", consisting of a paper by Reppert, responses by Theodore M. Drange, William Hasker and Keith Parsons, and a second paper by Reppert replying to these three critics.
