A branch of Simple Realism based off the counterargument:
- Every Moral Fact can either have or not have a reason.
- Because, a reason is not required, the property of having a reason is a Irreducible Property
- Since, reason is itself a moral property (and also a normative property), reductionism fails Reductionism that allows for normative properties will say that: Reasons can also be non-moral, thereby allowing Reductionism to survive.
