The Different Types of Philosophy

We are going to be talking about philosophy, but because I think you mentioned this just a minute ago, the topic of free will. So although we're both philosophers, we will be talking about some science and theology as well. Do we have free will? And what is free will anyway? What is it anyway? Maybe you could talk about some of the different ways of kind of trying to explain what philosophy is now that we have some examples on the table.
