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.

What is opposition?

Opposition is the repugnancie or contrarietie of two extremes which are contrary one to another, in such sort as none of them is in like manner repugnant to any other thing: as for example, white and blacke being two extremes, are more contrary one to another, then either of them is to any other colour, as to red, yel∣low, russet, or blew.

Sith some things are said to be agreeable one to another, and some contrary one to another, and some diuers one from another; it were not amisse, first here to tell how, and when things are said to be agreeable, diuers, or repugnant one to another.

Things are said to be agreeable one to another three manner of waies: First, when they agree in generall kinde, as those which are subiect to one next generall kinde, as man and horse do agree in generall kinde, because this word animal, or sensible body, is the next generall kinde to them both. Secondly, things are said to agree in speciall kinde, as Edward and Iohn are both compre∣hended vnder this word man. Thirdly, things are said to agree in number, as words hauing one selfe signification, called in Greeke Synonyma, as a blade, a rapier, a curtilas or stucke, signi∣fying a sword: also things of like substance or definition, as man, and a sensible body endued with reason. And by these three waies things are said also to differ one from another; for they

may differ one from another in generall kinde, in speciall kinde, and in number: in generall kinde, as a sensible body, and a tree; in speciall kinde, as a horse, and an as•…•…e: againe, they may differ in number, as the Indiuiduums that be comprehended vnder one speciall kinde, as Iohn and Edward, doe differ only in number.
