 hence, the ontological commitment of (3) is reducible to individuals (red things). According to Brentano, terms referring to entia rationis are actually not expressions functioning as names, but they belong to so-called syncategorematica (or synsemantica), that is, the category of expressions not having an autonomous meaning, but only a contextual one as for example, logical constants (‘and’, ‘or’, etc.). Omitting sentences, only names of particulars are categorematic (or autosemantic). On the other hand, the nouns used to refer to entia rationis are useful because they simplify our discourse.  Nevertheless, we could live without abstract terms.
