If it meant '_Some only_,' every particular proposition would be an exclusive exponible (chap.

3); since _Only some men are wise_ implies that _Some men are not wise_.

Besides, it may often happen in an investigation that all the instances we have observed come under a certain rule, though we do not yet feel justified in regarding the rule as universal; and this situation is exactly met by the expression _Some_ (_it may be all_).
The words _Many_, _Most_, _Few_ are generally interpreted to mean _Some_; but as _Most_ signifies that exceptions are known, and _Few_ that the exceptions are the more numerous, propositions thus predesignate are in fact exponibles, mounting to _Some are_ and _Some are not_.

If to work with both forms be too cumbrous, so that we must choose one, apparently _Few are_ should be treated as _Some are not_.
The scientific course to adopt with propositions predesignate by _Most_ or _Few_, is to collect statistics and determine the percentage; thus, _Few men are wise_--say 2 per cent.
The Quantity of a proposition, then, is usually determined entirely by the quantity of the subject, whether _all_ or _some_.
