The arte of logick Plainely taught in the English tongue, according to the best approued authors. Very necessary for all students in any profession, how to defend any argument against all subtill sophisters, and cauelling schismatikes, and how to confute their false syllogismes, and captious arguments. By M. Blundevile.

Shew how they are defined and diuided.

Linea (in English, a line) is a length without either bredth or thicknesse, which is either right, or crooked; •…•…ight, as a yard, an ell, or pole; crooked, as a hoope, or circle.

Superficies (which wee may properly interprete to be the vp∣per face of any thing) is a length and bredth without depth or thicknesse; and that is either plaine, or bowing; plaine, as a plaine or smooth floore; bowing or compassing, as a vault or ouen, whereof the outward side is called conu•…•…x, and the inward side concaue or hollow.

Corpus (which is as much to say as a body) is that which hath both length, bredth, and depth, and that is either round, or with angles; round, as a bowle or ball; with a•…•…gles or co•…•…ners, as a square die, or such like thing. All which three kindes of quantitie are to be considered onely with the minde mathematically. as things abstract, and separated from all k•…•…nde of matter, t•…•…at is to say as things that haue no being •…•…t al, but imaginatiuely▪ and yet so nec•…•…ssarily inuented by man, as nothing can be measured with∣out

them. To these three kindes of whole quantitie may be also added two other kindes, that is to say, mouing, and time, being taken for the measure, space, or distance of place or time wherein any thing is moued.
