An important instance of probabilistic logic is presented in inductive logic, as devised by Carnap, Hintikka and others (Carnap 1950 and 1952, Hintikka and Suppes 1966, Carnap and Jeffrey 1970, Hintikka and Niiniluoto 1980, Kuipers 1978, and Paris 1994, Nix and Paris 2006, Paris and Waterhouse 2009). Historically, Carnapian inductive logic developed prior to the probabilistic logics referenced above, and more or less separately from the debates in the philosophy of statistics. But the logical systems of Carnap can quite easily be placed in the context of a logical approach to Bayesian inference, and doing this is in fact quite insightful.
