Explanation

Contradictories pair with E and I, contraries with A and E, sub-contraries with I and O, and subalternation with A and I.

Contradictories differ in both quantity and quality and cannot share a truth-value, as with E and I.

Contraries are the two universals A and E, which cannot both be true.

Sub-contraries are the two particulars I and O, which cannot both be false.

Subalternation links a universal to its particular of the same quality, as A to I.
