 An old tradition has it that there are two branches of logic: deductive logic and inductive logic. More recently, the differences between these disciplines have become so marked that most people nowadays use “logic” to mean deductive logic, reserving terms like “confirmation theory” for at least some of what used to be called inductive logic. I shall follow the more recent practice, and shall construe “philosophy of logic” as “philosophy of deductive logic”.
