Everyone has their own inner philosopher-a voice within that asks, oh so insistently, philosophical questions. Everyone wants to know what the ultimate nature of the world is, what the self is, whether we have free will, how our minds relate to our bodies, whether we can really know anything, where ethical truth comes from, what the meaning of life is, and whether or not there is a God. This inner philosopher is related to the inner child, since the child too is prone to asking philosophical questions. But it is much better to have a disciplined guide through philosophy than simply to try to do all the thinking by yourself. I will be acting as your guide. I will cover all the main problems of philosophy, from logic to ethics, from the human mind to God, introducing you to how philosophers think and the theories they have come up with. The first four lectures focus on foundational questions that need to be clarified before we engage upon more applied discussions. We need to know what knowledge is, what truth is, and what logical reasoning is before we start discussing ethics, the mind, free will and God. So let's start with the basics, then break into a run only when we have learned how to walk.
