The French discourse model of human communication is largely an engagement of the problematic concept of enlightenment as a product of the ability to reason by thinking. The engagement as speaking and writing becomes thematic, when one considers that, the product called "reason" also should explicate the process wherein the conscious experience of being is essentially "reasonable" in doing as listening and reading. The engaged analysis of reason differentiates among parole, discours, langue, and langage as a synthesis of logic mediating rhetoric and grammar as models of expression and perception. The method is known as the trivium in the Medieval universities of Europe, subsequently adopted as a pedagogy throughout Europe, and last, adopted by C. S. Peirce as a foundational semiotic methodology for science (methodeutic). The influence of the human science adaptations emerges in France with the philosophic cross-over and intertwined (chiasm) positions of Existentialism, Phenomenology, Structuralism, and Semiology. Doing the reasonable requires metaphor and metonymy, simile and synecdoche in the service of expression, yet, it also demands the perception of their respective counterparts in allegory, analogy, allegoresis, and aphorism. The human journey from thinking to speaking to doing and the return (renvoi) is one of ingenuity made eloquent in the face of crisis. It was so for the Ionian enlightenment, it was so for the European enlightenment, and it is so for us. [ABSTRACT FROM AUTHOR]
