5. Three Kinds of Optimism
- About this Lecture
About this Lecture
In the previous module, we saw how moral reasons might be considered objective not because they are external, but because they are universal. In this module, we look more closely at that concept of universality. Does it include all rational beings, or just all humans? Does it matter if moral reasons are not in fact universal? Does it matter if objective moral rules don’t in fact exist at all?
In this course, Professor James Lenman (University of Sheffield) explores one of the key questions in metaethics: do objective moral reasons exist? After a brief discussion of what we mean when we talk about reasons, we spend the bulk of the course exploring three theories that explain where our reasons come from. In the first two modules, we think about the Simple Desire View, the idea that our reasons are simply extensions of our desires. After that, in the third module, we turn to the concept of externalism and the idea of external moral reasons, and the objections to this position made by philosophers such as J. L. Mackie. In the fourth and fifth modules, we explore the concept of Ideal Desire Theory, which states that the objectivity of moral reasons may be based not on their externality, but their universality. The course ends with a brief discussion of the extent of this universality, and the consequences (if any) of there being no objective moral reasons.
