 Dewey’s pragmatist moral epistemology follows from his instrumental account of value judgments. It is uncontroversial that instrumental judgments are subject to empirical testing and confirmation, since they involve empirical claims about causation. We test scientific hypotheses by bringing about their antecedents and seeing if the results are as they predicted. Similarly, we test value judgments by acting on them and seeing if we value the consequences in the way the judgment predicted. Acting on our value judgments — putting them into practice — supplies the data for confirming or disconfirming them.  Roughly speaking, a value judgment hypothesizes “try it, you’ll like it” — a statement easily subject to empirical verification and refutation. Intelligent value judgments proceed not by random trial-and-error, but from skilled projection of prior confirmed “try-like” regularities to analogous novel situations, which are continuously modified in light of experiences of the wider consequences of trying in these new situations.
