¶Of the powers of the soule. Chap. 7.
IF we take héed to the soule in com∣parison to his working, wee finde three manner of vertues, Vegetabilis, that giueth lyfe, Sensibilis, that giueth feeling, Racionalis, that giueth reason. In diuerse bodyes the soule is sayde to be thrée folde, that is to saye, Vegetabi∣lis that giueth lyfe, and no féeling, and that is in plants and rootes, Sensibilis, that giueth life & féeling, and not reason, that is in vnskilfull beasts, Racionalis that giueth lyfe, féeling, and reason, and this is in men. The Philosopher lyke∣neth the soule that is called Vegitabi∣lis, to a Triangle. For as a Triangle hath thrée corners, this manner soule hath thrée vertues, of begetting, of nourishing, and of growing. And this soule Vegetabilis is lyke to a Triangle in Geometrie. And hée lykeneth the soule Sensibilis, to a quadrangle square, and foure cornerd. For in a Quadran∣gle is a line drawne from one corner to another, before it maketh two Tri∣angles and ye soule sensible maketh two triangles of vertues. For where euer the soule sensible is, there is also the soule Vegetabilis, but not backwarde. And hée lykeneth the soule Racionabi∣lis to a Circle, because of his perfection and conteining. For of all the figures that be called Isoperimetra, that is of al the figures of the same length the Cir∣cle is most, and most conteineth.
Though the soule reasonable be made perfect in cunning and vertues, as it is sayde in Liber de Anima: it is most per∣fect, and most may conteine in the man∣ner of a Circle, touching the kindly ver∣tues. And therefore who that hath the soule reasonable, hath also the power Sensibilis and Vegetabilis, but not con∣trariwise.
