  The theses (R1)–(R3) concern an ontological dimension of reism or ontological reism. However, Kotarbiński’s reism, like Brentano’s version of this view, also has a semantic dimension. Semantic reism is a theory of language. In particular, it is a theory of names. According to this account, names occurring in ordinary parlance can be divided into two categories: genuine names and non-genuine names (i.e., apparent names, onomatoids). The former category is reduced to names of things in the sense of (R1) and (R3). Now, onomatoids seem to refer to abstract objects, but that is a mistake, because such objects do not exist by standards of reism. Kotarbiński supplemented this distinction with a theory of sense. Only sentences with genuine names (and logical constants) have a literal meaning (sense). If a sentence with onomatoids is replaceable by a sentence with genuine names only (call such sentences “reistic”), it is meaningful, if not it is meaningless. Consider:
