Philosophical Problems Podcast artwork

In this subject we examine some of the central problems that have captivated philosophers throughout millennia, as well as those that scientific advances and cultural changes have only recently brought to our attention. These might include: where did the universe come from? Might a machine think? Is time travel possible? Is it morally acceptable to eat meat, or to design children genetically? Does the world suggest the existence of a designer, a God? Students will focus on examining the merits of the various arguments on these issues, dealing with each philosophical problem for a week. Students will be introduced to most of the major philosophical areas, including epistemology (what can we know?), metaphysics (what is the nature of reality?), ethics, personal identity, and philosophy of mind.

Free Will II

May 22 2013 50 mins

While the question concerning the truth of determinism may be an empirical question, that is, it will be settled by the various sciences, philosophers are particularly interested in whether or not the hypothetical truth of determinism would rule out free will. In this lecture, we look at two opposing positions on this issue: those who think that determinism is compatible with havin

Free Will I

May 19 2013 50 mins

If the world is causally determined, does this mean people no longer have free will? Or is being free compatible with determinism. In this lecture, I discuss two opposing positions regarding the existence of free will even though both agree that genuine free will is incompatible with determinism. On the one hand, there are hard determinists who think that because determinism is tru

Artificial Intelligence II

May 13 2013 45 mins

Two of the most vocal critics of the idea that information processing machines may be said to think, or show intelligence, are Hubert Dreyfus and John Searle. This lecture briefly addresses some of Dreyfus' thoughts in this regard, which hinge on the contrast between know-how and knowledge-that, before turning to consider Searle's famous "Chinese Room" thought experiment and the va

Artificial Intelligence I

May 08 2013 43 mins

This lecture introduces students to the work of Alan Turing and the project of creating Artificial Intelligence that he played a significant role in inaugurating. We consider some of the objections to standard forms of AI (but not necessarily all) posed by Hubert Dreyfus in various of his books.

The Consciousness Conundrum II

May 07 2013 50 mins

In this lecture we discuss two competing solutions to the mind-body problem. First, we look at the identity theory of mind, or reductive materialism, which says that the mind is identical to the brain. Then, we look at property dualism, which agrees with the materialist that there is only one type of substance but differs on the type of properties the substance can have. Copyright

The Consciousness Conundrum I

May 05 2013 49 mins

The mind appears to be of a radically different nature to the everyday material items we normally encounter. Insofar as our body, including our brain, are considered parts of the material world, it becomes a mystery as to how our mind can find a place within nature and interact with out body. This is what is known as the mind-body problem. After trying to make sense of the problem,

Other Minds

Apr 29 2013 48 mins

Do we know that others have minds? This lecture considers two main types of response to the “problem of other minds”: those that are inferential in nature and argue that perception of others alone is an insufficient justification, requiring either an argument by analogy, or an inference to the best explanation; those that are non-inferential in nature, advocating either direct

The Problem of Induction

Apr 22 2013 51 mins

This lecture is a discussion of the problem of induction. I begin by looking at the structure of logical reasoning with a view to delineating the ‘problem’ with inductive reasoning; this is a problem for scientific knowledge as inductive reasoning is essential to science. I explore Hume's analysis of the problem of induction with a view to showing how deep the problem runs. I e

Brain-snatched II

Apr 17 2013 51 mins

This lecture continues the discussion of scepticism introduced in the preceding lecture. There is discussion of different views about what the consequences would be for someone who accepted scepticism, and of some of the arguments that have been given for rejecting scepticism.

Brain-snatched I

Apr 15 2013 49 mins

This lecture deals with philosophical scepticism about the physical world. This is the idea that we do not really have any evidence (at all!) for any of our ordinary beliefs about the world around us, because we cannot rule out the possibility that all our experience is some sort of massive illusion. We look at the detail of the argument for this startling view, and at one of the r
