If a speaker argues that something is morally right or wrong, which type of proposition are they using?

When a speaker argues that something is morally right or wrong, they are using a proposition of value. This type of proposition focuses on judgments about the worth, goodness, or ethics regarding a particular idea, action, or object. It involves asserting what is valuable or desirable in a moral context. For example, if a speaker states that honesty is a virtue, they are expressing a value judgment about honesty.

Propositions of policy, on the other hand, concern recommendations for actions or changes that should be taken, such as advocating for a new law or regulation. Propositions of fact are statements that can be verified or disproved with evidence; they deal with objective truths or realities. Propositions of alternative are less commonly recognized in argumentation and often refer to presenting different options or choices without a direct value judgment. Thus, the nature of the claim about morality directly aligns with propositions of value.
