Abstract

Postmodern methodology in the human sciences and philosophy reverses the Aristotelian laws of thought such that (1) non-contradiction, (2) excluded middle, (3) contradiction, and (4) identity become the ground for analysis. The illustration of the postmodern logic is Peirce’s (1) interpretant, (2) symbol, (3) index, and (4) icon. The thesis is illustrated using the work of Merleau-Ponty and Foucault and the le même et l’autre discourse sign where the ratio [Self:Same :: Other:Different] explicates the communicology of Roman Jakobson in the conjunctions and disjunctions, appositions and oppositions of discours, parole, langue, and langage.
