1908-1961. French philosopher, one of the most significant contributors to phenomenology after Edmund Husserl. He attempted to move beyond the notion of a pure experiencing consciousness, arguing in The Phenomenology of Perception 1945 that perception is intertwined with bodily awareness and with language. In his posthumously published work The Visible and the Invisible 1964, he argued that our experience is inherently ambiguous and elusive and that the traditional concepts of philosophy are therefore inadequate to grasp it.
