Abstract

We discuss the implications of the findings reported in the target article for moral theory, and argue that they represent a clear and genuine case of fundamental moral disagreement. As such, the findings support a moderate form of moral anti-realism – the position that, for some moral issues, there is no fact of the matter about what is right and wrong.
