Modus Dimatis

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

Some P are M.
All M are S.

Some S are P.

For example:

Some rhombuses are squares.
All squares are rectangles.

Some rectangles are rhombuses.

Modus Dimatis is very similar to Modus Darii, the only difference is that the major and minor statements are swapped.

Name

The name “Dimatis” is a mnemonic term that helps to remember the most important characteristics of this mode: The “D” at the beginning indicates that it is related to the Modus Darii, the two “i” and the “a” indicate the affirmative existential and universal statements that make up this form.
