 Meinong answered objection (1) by denying that beingless objects must obey the law of noncontradiction — only actual and possible objects do (1907, §3: 16). On the contrary, thinking about impossibilia makes the suspension of the law of noncontradiction indispensable. Meinong’s later appeal to the above-mentioned distinction between negation in a wider and narrower sense (5.2.1) shows that he meant only the law of noncontradiction in its traditional, ontological and not in its logical, propositional form. According to Meinong’s characterization principle, the round square is both round and non-round, but it is not the case that (i) the round square is round and (ii) the round square is not round (i.e., it is not the case that the round square is round). The triangle is neither green nor non-green, but nevertheless it is the case that the triangle is either green or not green. In such cases, Meinong does not accept that the predicate negation “A is non-B” is equivalent to the sentence-negation “Not (A is B)”. The equivalence of both kinds of negation “(~F)x ↔ ¬(Fx)” does not hold for impossibilia and incomplete objects but only for actual and possible objects where “possible” seems to be taken in a strong sense that relates possibility with completeness: “Only complete objects are possible” Meinong says in a lecture note dating from 1910 (1978: 228). (To see that there is still a problem left, see 5.2.1 above; cf. also Swanson 2011 which criticizes Meinong’s distinction between narrow and wide negation and argues that Russell’s account is to be preferred to a (Neo-)Meinongian view.)
