8. Anti-Realism and Nihilism

About this Lecture

Lecture

In this module, we think about the extent that moral anti-realism leads to nihilism – and if so, will this result in the collapse of morality as we know it?

Course

In this course, Dr Luke Elson (University of Reading) explores what it means to be a moral anti-realist. We begin in the first module by thinking about what moral anti-realism actually is. After that, in the second module, we outline four reasons why someone might be an anti-realist. In the following three modules, we think about three anti-realist positions: first, A. J. Ayer’s theory of emotivism; second, R. M. Hare’s theory of prescriptivism; and third, J. L. Mackie’s Error Theory. In the sixth and seventh modules, we think about two of the major weaknesses of anti-realism: first, its inability to explain moral disagreements; and second, its inability to explain moral progress. Finally, in the eighth module, we think about the extent to which moral anti-realism leads to nihilism. And in that case, why be moral at all?
