CHAPTER II. Ogg disjunctive : as, The earth moves in a circle or an ellipsis ; but it does not move in a circle ; therefore it moves in an ellipsis. A disjunctive syllogism may have many members or parts : thus, it is either spring, summer,. autumn, or winter; but it is not spring, autumn or winter ; therefore it is summer. The true method of arguing here, is " from the assertion of one, to the denial of the rest, or from the denial of one or more, to the assertion of what remains ;" but the major should be so framed,, that the several parts of it cannot be true together, though one of them is evidently true. IV. A relative syllogism requires the major proposition to be relative ; as, where Christ is, there shall his servants be ; but Christ is in heaven ; therefore his servants shall be there also. Or, as is the captain, so are his soldiers; but the captain is a coward : therefore his soldiers are so too. Arguments that relate to the doctrine of proportion, must be referred to this head : as, " As two are to four, so are three to six ; but two make the half of four ; therefore three make the half of six." Besides these, there is another sort of syllogism which is. very natural and common, and yet authors take very little notice of it, call it by an improper name, and describe it very defectively; and that is, V. A connexive syllogism. This some have called copu- lative ; but it does by no means require the major to be a copu- lative nor a compound proposition (according to the definition given of it, Part II. Chap. II. Sect. 6.) but it requires that two or more ideas be so connected either in the complex subject or predicate of the major, that if one of them be affirmed or denied in the minor, common sense will naturally spew us what will be the consequence. It would be very tedious and useless to frame particular rules about them, as will appear by the following ex- amples, which are very various, and yet may be farther mul- tiplied. (1.) Meekness and humility always go together : Moses was a man of meekness ; therefore Moses was also humble. Or . we may form this minor, Pharoab was no humble man ; there- fore hé was not meek. (2.) No man can serve God and Mammon ; the covetous Man serves Mammon ; therefore he cannot serve God. Or the minor may run thus, the true Christian serves God, therefore he does not serve Mammon. (3.) Genius must join with study to make a great man, Florino has genius, but he cannot study ; therefore Florino will never be a great man. Or thus, Quintus studies hard, but has no genius; therefore Quintus will never be a great man. (4.) Gulo cannot make a dinner without flesh and fish ; there was no fish to be gotten to -day i therefore Gulo this day cannot make a dinner. 01$11id. ÍÌ
