A Class Room Logic / Deductive and Inductive, with Special Application to the Science and Art of Teaching

by George Hastings McNair

The p in Darapti indicates that the proposition represented by the preceding vowel must be converted by limitation. This proposition is the minor premise; converting it by limitation gives: “Some sympathetic persons are true teachers.” As there are no other significant letters the reduction is complete and we have this:

A   All M
true teachers are G
just,

I   Some S
sympathetic persons are M
true teachers,

I ∴ Some S
sympathetic persons are G
just.

The symbolization indicates that the mood is A
I
I of the first figure, or is in Darii.

(2) Given: A syllogism in Camestres A
E
E

A   All G
true teachers are M
just,

E   No S
one who shows partiality is M
just,

E ∴ No S
one who shows partiality is a G
true teacher.

The symbols show that the mood is AEE of the second figure or in Camestres. Judging from the initial letter C, the mood in Camestres must be reduced to the mood in Celarent E
A
E.
