Abstract
[In French] This paper outlines Merleau-Ponty’s interpretation of higher-order cognition as a fundamentally embodied process that is enacted by motor subject situated in natural and cultural environment. More specifically, I exemplify Merleau-Ponty’s interdisciplinary approach to cognition on his interpretations of motor intentionality, operative speech, and mathematical reasoning, which are based on neuropathology, linguistics, and gestalt psychology, respectively. In this analysis, I aim to show that the body is involved in cognition as an operator of the phenomenal structuration of the environment even at the level of linguistic, rational, and abstract experience.
