preindesignate

Now, the rule is that preindesignate propositions are, for logical purposes, to be treated as particular; since it is an obvious precaution of the science of proof, in any practical application, _not to go beyond the evidence_.

Thus, if there is a predication concerning 'Some S,' or 'Some men,' as in the forms I. and O., we cannot infer anything concerning 'All S.' or 'All men'; and, as we have seen, if a term is given us preindesignate, we are generally to take it as of particular quantity.

In converting I., the predicate (P) when taken as the new subject, being preindesignate, is treated as particular; and in converting E., the predicate (P), when taken as the new subject, is treated as universal, according to the rule in chap.v. § 1.

Propositions whose quantity is thus left indefinite are technically called 'preindesignate,' their quantity not being stated or designated by any introductory expression; whilst propositions whose quantity is expressed, as _All foundling-hospitals have a high death-rate_, or _Some wine is made from grapes_, are said to be 'predesignate.'

Still, the rule may be relaxed if the universal quantity of a preindesignate proposition is well known or admitted, as in _Planets shine with reflected light_ -- understood of the planets of our solar system at the present time.

Again, such a proposition as _Man is the paragon of animals_ is not a preindesignate, but an abstract proposition; the subject being elliptical for _Man according to his proper nature_; and the translation of it into a predesignate proposition is not _All men are paragons_; nor can _Some men_ be sufficient, since an abstract can only be adequately rendered by a distributed term; but we must say, _All men who approach the ideal_.
