We make moral judgements all the time, every time we say something is good, bad, evil, or right. Despite their ubiquity, we do not usually stop to wonder whether making moral judgments is a good thing. Nor do we typically even ask what the point of making a moral judgement is. These are some of the questions that those who study ethics pose, especially in the sub-field of meta-ethics. I'm going to talk to Dr Eric Campbell about some of these tricky questions about moral systems and how we might think about them differently and a little more deeply.
