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.

Which call you dissimilar or vnlike?

Those parts that differ both in kinde and name, as the head, brest▪ bellie, armes, and legges, are the parts dissimilar of a mans body: likewise a house, a ship, and many other things, haue also such parts, of any one of which parts the whole cannot be spo∣ken: for you cannot say, Because here is the head of a man, Ergo here is a man. Againe, of these dissimilar parts, some are called principall, whereof if any be wanting, the whole must needs pe∣rish; as without the head, bellie, heart, liuer, or guts, mans body cannot be. The not principall, are those parts without the which the body may be: for though those parts be wanting, yet the bo∣dy is counted a whole thing, though not perfect in euery point, as without arm•…•…s, hands, legges, or feet, the body may liue: that building also that hath a foundation, walles, and roofe, is coun∣ted to be a whole house, though it hath neither doores nor win∣dowes, yet not perfect in euery respect.
