Modus Celaront
Form of a syllogism based on the Modus Celarent, in which a negative existential proposition is inferred from positive and negative universal premisses.
No M is P.
All S are M.
[and there exists at least one S]*
Therefore, some S are not P.
For example:
No rectangle is a circle.
All squares are rectangles.
[and there exists at least one square]*
Therefore, some squares are not circles.
Modus Camestros is similar to Modus Cesaro, the only difference is that the terms in the major statement are swapped.
Name
The name “Celaront” 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” and “e” mark the affirmative and negative universal statements in the premisses, the “o” a negative existential conclusion.
