Metaphysics concerns itself with certain fundamental questions about reality, which include the questions of what there is, what we are and why we need to take these questions seriously.  To the question of what there is, materialists’ answer is that material things, and only material things, exist.  Is it the case that only material things exist?  Or do material things exist at all?  Do non-material things such as mind, qualities, time, causal relation and numbers exist?  Besides the above questions, this course also addresses the mind-body problem and the reality of free will.
