(ethics) a doctrine holding that moral statements prescribe appropriate attitudes and behavior WordNet 3.0 & Open English WordNet

Universal prescriptivism is the meta-ethical view that claims that, rather than expressing propositions, ethical sentences function similarly to imperatives which are universalizable—whoever makes a moral judgment is committed to the same judgment in any situation where the same relevant facts pertain.
