Merleau-Ponty (b. 1908–d. 1961) was a major 20th-century French philosopher and contributor to phenomenology. He studied at the École Normale Supérieure from 1926 to 1930, received the aggrégation in philosophy in 1930 and the Docteur ès lettres in 1945. After early teaching largely in psychology, culminating with a Sorbonne appointment as professor of child psychology and pedagogy, he was elected in 1952 to the Chair in Philosophy at the Collège de France, as the youngest philosopher ever in this position, which he held until his death. His inaugural lecture was published as Éloge de la philosophie (In Praise of Philosophy). In 1945, Merleau-Ponty became, along with Raymond Aron, Simone de Beauvoir, and Jean-Paul Sartre, a founding editorial board member as well as political editor of Les temps modernes, a journal devoted to “la philosophie engagée.” In 1953 he resigned from the journal. After the Korean conflict, Merleau-Ponty’s political difference with Sartre was acute, and in Les aventures de la dialectique (Adventures of the Dialectic) Merleau-Ponty characterizes Sartre’s position as “ultra-bolshevism.” Eventually, Merleau-Ponty would relinquish Marxist tenets. Merleau-Ponty’s first book, La structure du comportement (The Structure of Behavior), from 1942, is largely a critique of behavioral psychology as lacking a-propos, his stated goal, understanding the relation between nature and consciousness. His second and major completed book is La phénoménologie de la perception (Phenomenology of Perception). In this work Merleau-Ponty undermines classical theories of perception, which rely on “sense data”; introduces his understanding of the “lived body”; accentuates Husserl’s remark that consciousness is initially a matter of an “I can,” not an “I think”; and introduces a gestural analysis of language. While affirming Eugen Fink’s observation that there is no total “reduction” phenomenologically, Merleau-Ponty proceeds under the “epochē,” nonetheless. When he died, Merleau-Ponty was writing what would have been a book of major proportions. The material that he completed was posthumously published as Le visible et l’invisible (The Visible and the Invisible), a title from working notes that were published with it. Critical discussions of reflective philosophy, dialectic, and intuition precede a decidedly ontological project involving: “la chair” (the “flesh”), successor to Phenomenology of Perception’s “lived body,” through which “I live the world”; “reversibility,” the perceptual dynamic operative in our habitation of the world; and “the chiasm” or “intertwining” of different contexts, such as vision and motility. L’oeil et l’esprit (Eye and Mind), intended for inclusion in The Visible and the Invisible but published separately, addresses exploration of these factors in painting.
