 The supreme moral law that Bolzano put in place of Kant’s Categorical Imperative was by no means original. Bolzano, however, modified and justified it in an original way and consistently applied it to many different areas. By the supreme moral law Bolzano means “a practical truth [i.e., a true ought proposition] from which every other practical truth […] can be derived objectively, i.e., as the consequence from its ‘ground’” (RW I, 228; cf. also RW I, 44, 244, 256, RW IV, 27, 217, 221, and WL II, 348, WL IV, 178). Thus, on the basis of the asymmetry of Bolzano’s entailment relation (Abfolge), the supreme moral law must be an ought proposition that does not objectively follow from (i.e., it is not entailed by) any other ought proposition. It must therefore be a basic truth, i.e., a truth that does not have an objective “ground”, but can only \(be\) an objective “ground” of other (practical) truths (WL II, 375, RW I, 229, RW IV, 207).
