 In contrast to ideas and propositions (i.e., “objective” ideas and “objective” propositions), subjective ideas and subjective propositions belong to the real world, in particular to World 2 of mental phenomena and mental processes. For Bolzano, a subjective idea as well as a subjective proposition is a real property (or “adherence”) of the thinking being in whose mind it appears, or rather of this being’s mind or “soul” itself (WL III, 6, 10 f., 109). A subjective idea is a mental phenomenon — i.e., an attribute of a mind — that “grasps” an idea (in the “objective” sense of the word); and a mental phenomenon that “grasps” a proposition is called ‘Urteil’ (‘judgment’) by Bolzano (WL III, 108). In addition to judgments, there is a second kind of subjective propositions, viz. propositions that are “merely thought” (bloß gedacht); a “merely thought proposition” is in fact a subjective idea of a proposition, i.e. a mental phenomenon which grasps an idea whose object is a proposition (WL I, 155). Merely having a subjective idea of a proposition does not require that we assert the truth of the proposition in question, whereas a judgment is an act (Handlung) of asserting the truth of the proposition grasped by the judgment (WL III, 108, 199).
