Moral claims are a type of normative claim.
For this to be helpful we need to say something about normative claims.
A “claim” is statement that asserts something that could be either true or false.
A DESCRIPTIVE claim is a claim that asserts that such-and-such IS the case.
A NORMATIVE claim, on the other hand, is a claim that asserts that such-and-such OUGHT to be the case.
Normative claims make value judgments. Descriptive claims do not make value judgments.
These are all descriptive claims. They make no value judgments.
These are all normative claims. Each one of them expresses a value judgment of some kind.
However, only the last one expresses a moral claim. The others express different kinds of non-moral normative values, and make different kinds of normative judgments.
Let’s take a closer look at these different kinds of normative values, so that we have a better idea of what distinguishes moral values and moral claims.
