 The manuscript and working notes published posthumously as The Visible and the Invisible (1964 V&amp;I), extracted from a larger work underway at the time of Merleau-Ponty’s death, is considered by many to be the best presentation of his later ontology. The main text, drafted in 1959 and 1960, is contemporaneous with “Eye and Mind” and the Preface to Signs, Merleau-Ponty’s final collection of essays. The first three chapters progressively develop an account of “philosophical interrogation” in critical dialogue with scientism, the philosophies of reflection (Descartes and Kant), Sartrean negation, and the intuitionisms of Bergson and Husserl. These are followed by a stand-alone chapter, “The Intertwining—The Chiasm”, presenting Merleau-Ponty’s ontology of flesh. The published volume also includes a brief abandoned section of the text as an appendix and more than a hundred pages of selected working notes composed between 1959 and  1961.[7]
