Propositions

,

in logic, are of four kinds, called A, E, I, O. “A” is a universal affirmative, and “E” a universal negative; “I” a particular affirmative, and “O” a particular negative.

“Asserit A, negat E, verum generaliter ambo!

Asserit I, negat O, sed particulariter ambo.”

A asserts and E denies some universal proposition;

I asserts and O denies, but with particular precision.
