 At first glance, this objective distinction among propositions seems to be far away from the Kantian distinction between judgments a priori and a posteriori. Nevertheless, the two distinctions are closely interrelated, and they almost coincide (WL II, 36); hence, Bolzano warns against confusing them (WL IV, 451 f.). The close relationship of the two distinctions becomes obvious as soon as we ask ourselves how to discover of a conceptual or an empirical proposition whether or not it is true: In the case of conceptual propositions, it is mere reflection, i.e., an inner “inspection” of our subjective concepts, without any experience, that is required to find out whether or not it is true, whereas in the case of an empirical proposition experience is indispensable for judging its truth or falsity (WL II, 36). This Kantian distinction of the different ways of recognizing the truth or falsity of such judgments, however, as important as it is, must be based on the more fundamental objective distinction between conceptual and empirical propositions on Bolzano’s view.
