The True and the Evident
way. One can deny certainty or validity of a judgement; one can deny modesty of a request;
and, more generally, one can deny, of any A, a B. Sigwart himself makes such denials, just
as everyone else does. Indeed, he often speaks with far more correctness than his theory
would allow, thus giving instinctive witness to the truth. According to his theory, the only
thing that can be denied is validity, and this is always denied of judgements; but he tells
us, on p. 151 for example, that “of any subject, an unlimited number of predicates may be
denied”. This is certainly correct, and it is precisely for this reason that we are justified in
retaining the ancient doctrine that there are two co-ordinate species of judgement.
