Chatton seemed to think that relying on this standard would yield bad results in certain cases; in particular he thought that despite Ockham’s insistence to the contrary, certain semantic arguments could be adduced to establish the existence of a restricted class of relations. He developed his attack on Ockham and supported his own ontological commitment to real relations with a counter-razor he called propositio mea = ‘my proposition’ and an ars respondendi = ‘a method of responding’, and also simply regula mea = ‘my rule’. I shall call it the ‘Chatton Principle’, to contrast with ‘Ockham’s Razor’.
