[Footnote 26: For those who would make a further study of the syllogism the

following rules are given: 1. In a syllogism there should be only three terms.

2. Of these three only one can be the middle term. 3. One premise must be

affirmative. 4. The conclusion must be negative if either premise is negative.

5. To prove a negative, one of the premises must be negative.

 

_Summary of Regulating Principles_: 1. Terms which agree with the same thing

agree with each other; and when only one of two terms agrees with a third term,

the two terms disagree with each other. 2. "Whatever is affirmed of a class may

be affirmed of all the members of that class," and "Whatever is denied of a

class may be denied of all the members of that class."]

 

[Footnote 27: All the speakers were from Brown University. The affirmative

briefs were used in debate with the Dartmouth College team, and the negative

briefs were used in debate with the Williams College team. From _The Speaker_,
