Probabilistic reasoning allows us to act rationally under uncertainty. Logical inference allows us to act rationally given a set of premises and rules. If you want to know how to act rationally under uncertain premises, you need to define a probabilistic logic. If you don’t know how to do that, come to my talk and find out. I will review probabilistic logic in a brief and biased manner, and exemplify my perspective on the matter. I will also discuss key challenges of the field and propose some initial solutions in my area of interest.
