I appreciate the articulate thoughtfuless of your post and I do not condone the outright proselytizing of students to any doctrine, deism or atheism included. I want to say, however, that there is no religion I know of that is founded on rationality in particular. To call a religion irrational is to say it is founded on belief, something that cannot be proved. One may be convinced by something other than proof though. Since most undergraduate Philosphy courses begin with the study of logic, and such formulations are the basis of Classical Western Philosphy, I encourage seekers of wisdom to take classes in the Humanities (ones that focus on philosphers’ writiings) to cultivate wisdom. Proof is not integral to these courses.
