 How do these distinctions solve the problems raised above for the naive comprehension principle? Let us begin with Parsons’s view. Parsons focuses on the problems of contradiction and of the existent winged horse. Following Russell’s discussion of Meinong, in [Russell 1905a, 1907], Parsons considers the threat of contradiction generated by impossible objects like the round square. Meinong claimed that there is a round square, but that, complained Russell, leads to violations of the principle of noncontradiction, as that entity is then both round and not round, in light of the fact that it is square, which entails that it is not round. Parsons’s response (see [Parsons 1980], 38–42) seems to be to deny that being square entails not being round, in which case it is simply false that the round square is not round. He thinks that that implication holds only for “real” objects. He claims that there are counterexamples to the claim that all square objects are not round; after all, the round square is a square object that is round! This solution, however, does not seem to solve the more general threat of contradiction, as discussed above. Indeed, Parsons himself recognizes the limited success of his response (see [Parsons, 1980, 42n8]). He allows that being non-squared is a nuclear property. But then his comprehension principle entails that there is an object corresponding to the condition of being a non-squared square, where that object instantiates the incompatible properties of being a square and being a non-square. The threat of contradiction has not been silenced.
