Bayesian Practical Inference

In this essay, we will try to provide a formal analysis of practical inference, attentive to the various phases in which it is articulated, and being so capable of explaining both the logical conclusiveness of the inference and the probabilistic nature of its conclusion. An innovative purpose of this article is to show how the final deliberation leading to action— the ultimate practical judgment—takes place according to a logic consistent with the use of Bayes’ theorem. This is why we refer to Bayesian practical inference in the title of this essay.
