 Both Hume’s dictum and anti-brutalism put us in a position to pose a conditional challenge to the ethical realist. If the realist thinks that the ethical properties are distinct from the base properties, they must reject either metaphysical supervenience or Hume’s dictum. And if they think the supervenience of the ethical is a brute necessity, they need to explain why such brutalism is not objectionable. Different variants of ethical realism have different resources available to address this challenge. The remainder of this section examines some of these resources.
