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. ∴ No S is P.
For example:
All squares are rectangles. No rectangle is a circle. ∴ No square is a circle.
Modus Calemes is identical to the Modus Celarent, except that the premisses have been swapped.
Name
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.
