The aim of this course is to learn the basics of propositional modal logic and its applications throughout philosophy.
We will start with visual representations of possible worlds, and then turn to learning how to assess truth and validity relative to such worlds. After that, we will look at some very traditional topics: the temporal and epistemic interpretations of modal logic, supervenience, counterfactuals, and two-dimensional modal logics. We will use concerns about realism about possible worlds as a motivation to pursue deductive systems for modal logic. As we go along, we look briefly at contemporary philosophers like David Lewis and Robert Stalnaker, as well as discuss some well-known puzzles like Aristotle's Sea Battle and the Muddy Children puzzle.
