Summary of

Jean-Claude Dumoncel

“Les modalités deleuziennes”

Part I

La fondation leibnizienne

Section 0

[introductory material]

Brief summary (collecting those below):

(1.0.1) On account of his teacher Canguilhem, Deleuze was possibly familiar with Apuleius' square of logical oppositions. We will now examine Leibniz’ version. (1.0.2) Here is the the “AEIO” square of logical oppositions:

All              None

Some        Not all

x         ¬x

x         ¬∀x

(p.2)

(1.0.3) We can place the elementary logical modalities, possible and necessary, along with their variations, impossible and contingent, into their own oppositional square of modalities:

Necessary         Impossible

Possible          Contingent

□p         ¬◇p

p       ¬□p

(pp.2-3)
