Chapters 1 and 2 of Jaynes’ Probability Theory: The Logic of Science show how Bayes’ theorem follows necessarily from certain basic principles of plausible reasoning. In some sense all roads lead to Bayes when trying to derive a consistent mathematical procedure for manipulating degrees of plausibility.
You are quite right. I thought about mentioning the Cox-Jaynes road to Bayes’ theorem in my post, but decided that someone trying to reconstruct Bayes’ theorem would be more likely to get to it by muddling through intuitively via conditional probability.
