The rule of reason, conteinyng the arte of logique, set forth in Englishe, by Thomas Vuilson

¶Rules necessarie to be obserued in euerie diuision.

FIrst it must be prouided that the diuision as muche as maie be (for it cannot alwaies be so) ought to be made with twoo contrary differences, fully containyng in them self the whole cumpasse or wi∣denes of the generall worde, or that which is deuided, for it is a fault to for¦get any thyng, or let slip any part.

Againe the differences whiche de∣uide the generall worde, beyng ioined both together, must be egall to the said generall worde, and the partes coupe∣led together, must be asmuche as the hoole, or els the diuision is not good. A liuyng creature is deuided into his twoo differences, as into a thyng ha∣uyng reason, and a thyng that hath no reason. Nowe what so euer is a liuyng creature, the same is a thyng that ei∣ther

hath reason or els that lacketh rea¦son. And agayne euerie thyng that is endewed with reason, and without rea¦son, that same is a liuing creature. So that in euerie diuisiō, the membres, or partes that dooe deuide, by conuersion are turned with y^e thyng deuided, euen likewise it is with partitiō, as I haue spoken before of deuisiō. Where as lo∣gike hath two partes, Iudgement and findyng o••t of thynges, euen as I saie logique is nothing els but iudgement, and findyng out of thynges, so of the other side, iudgement, and findyng out of thinges, is nothyng els, but logique it self. Wherby appereth a plain•• con∣uersion, that what so euer the one is, the same is the other, whiche thyng must diligentlie be obserued in euerie diuision. Fo•• if the membres that do de¦uide, be either more or lesse than the thyng deuided: streight waie the diui∣sion is not good, for accordyng to a Pre¦cept that we haue in latine. Memb••a diuidentia semper cum diuiso conuer¦ti debent. The partes that do deuide must alway be equall with the thyng

deuided, and turned by cōuersion with the same, or els the diuision is not law∣full.
