Modus Calemes

Form of a syllogism based on the Modus Celarent, in which a negative universal proposition is inferred from an affirmative and a negative universal proposition.

All P are M.
No M is S.
Therefore, no S is P.

For example:

All squares are rectangles.
No rectangle is a circle.
Therefore, no square is a circle.

Modus Calemes is identical to the Modus Celarent, except that the premisses have been swapped.

The name “Calemes” is a mnemonic term that helps to remember the most important characteristics of this mode: The “C” at the beginning indicates that it is related to the Modus Celarent, the “a” indicates an affirmative, the two “e” negative universal statements.
