 When it comes to the question of how to interpret ought sentences, Bolzano — like most of his contemporaries — was obviously not aware of the fundamental problem involved in this question. Bolzano took ought sentences in his standard formulation without further ado as expressions of propositions, and he took it therefore for granted that they are true or false in the usual sense of these words, as explained by his definitions of truth and of falsity. He thus clearly held a cognitivist metaethical position, probably even a naturalistic one, using his utilitarian principle as a meaning postulate for ought sentences. In support of this understanding of Bolzano’s position, it can be put forward that Bolzano interpreted also other kinds of linguistic sentences in a simple naturalistic way. Even questions, e.g., are interpreted by Bolzano not as sentences expressing a wish for information but as describing such a wish and therefore being true or false in the usual sense of these words (WL I, 88, WL II, 71–76, 194–196).
