Abstract: A war is on in probability and statistics: between the objective approach, a.k.a. frequentist or orthodox statistics, and the subjective approach, a.k.a. Bayesian statistics. For my sins, I find myself fascinated by fields where the unorthodox view is correct, so I made and taught an undergraduate course on "Bayesian Inference and Reasoning." I will illustrate, with many examples, several hopefully transferrable aspects of the course.
