(Dr. Matthew Chrisman) We all live with some sense of what is good or bad, some feelings about which ways of conducting ourselves are better or worse. But what is the status of these moral beliefs, senses, or feelings? Should we think of them as reflecting hard, objective facts about our world, of the sort that scientists could uncover and study? Or should we think of moral judgements as mere expressions of personal or cultural preferences? In this module we’ll survey some of the different options that are available when we’re thinking about these issues, and the problems and prospects for each.

(Professor Duncan Pritchard) We know a lot of things – or, at least, we think we do. Epistemology is the branch of philosophy that studies knowledge; what it is, and the ways we can come to have it. In this module, we’ll take a tour through some of the issues that arise in this branch of philosophy. In particular, we’ll think about what radical scepticism means for our claims to knowledge. How can we know something is the case if we’re unable to rule out possibilities that are clearly incompatible with it?

(Dr. Guy Fletcher) The laws of a state govern what we can and cannot do within that state. But do we have an obligation to obey those laws? In this module, we'll discuss this question, together with some of the main positions that philosophers have developed in response to it. We'll start off by examining what obeying the law means exactly. Then we'll look at three factors that might form the basis of an obligation to follow the law. Finally, we'll discuss what the consequences might be if the problem can't be solved.

(Dr. Allan Hazlett) Much of what we think about the world we believe on the basis of what other people say. But is this trust in other people's testimony justified? In this module, we’ll investigate how this question was addressed by two great philosophers of the Scottish Enlightenment, David Hume (1711 - 1776) and Thomas Reid (1710 - 1796). Hume and Reid's dispute about testimony represents a clash between two worldviews that would continue to clash for centuries: a skeptical and often secular worldview, eager to question everything (represented by Hume), and a conservative and often religious worldview, keen to defend common sense (represented by Reid).

(Dr. Suilin Lavelle) If you’re reading this, then you’ve got a mind. But what is a mind, and what does it take to have one? Should we understand minds as sets of dispositions to behave in certain ways, as patterns of neural activation, or as akin to programmes that are run on the computational hardware of our brains? In this module, we’ll look at how and why recent philosophy of mind and psychology has embraced each of these options in turn, and think about the problems and prospects for each.

(Professor Michela Massimi) In this module we will explore a central and ongoing debate in contemporary philosophy of science: whether or not scientific theories are true. Or better, whether a scientific theory needs to be 'true' to be good at all. The answer to this question comes in two main varieties. Scientific realists believe that theories ought to be true in order to be good. We will analyse their main argument for this claim (which goes under the name of 'no miracles argument'), and some prominent objections to it. Scientific antirealists, on the other hand, defend the view that there is nothing special about 'truth' and that scientific theories and scientific progress can be understood without appeal to it. The aim of this session is to present both views, their main arguments, and prospects.

(Dr. Elinor Mason) We typically feel that the actions that we make are the result of our own free choices. But what if those actions are simply the end result of a long chain of cause and effect? What does this mean for free will? In this module, we'll look at the concept of determinism. In particular, we'll consider the implications that determinism might have for the notion of free will.

(Dr. Alasdair Richmond) In this module we'll think about some issues in metaphysics, a branch of philosophy that investigates the ways that reality could intelligibly be. Our case study will be the possibility, or otherwise, of time-travel. Some have thought that the apparent possibility of creating a machine that we could use to transport a person backwards in time can be ruled out just by thinking about it. But is time-travel really logically impossible? What would the universe have to be like for it to be possible? And can we know whether our universe fits the bill?
