Notice too that Chatton’s clause essentially forces us to hold time and movement as constants, and only then ask what would make the true proposition true. In this way, he forces us to see that a res must in fact be posited in such cases, since there is no change of place or lapse of time to explain the passage from contradictory to contradictory. By itself this begs the question against Ockham, and Chatton’s principle has no general leverage against Ockham. In the end the Chatton Principle had to be supplemented with direct attacks on Ockham’s alternative semantics, viz., connotation theory.
