In this book, Emmanuel Alloa offers a handrail for venturing into the complexities of the work of the French philosopher Maurice Merleau-Ponty (1908-61). Through a comprehensive analysis of the three main phases of Merleau-Ponty's thinking and a thorough knowledge of his many unpublished manuscripts, the author traces how Merleau-Ponty's philosophy evolved and exposes the remarkable coherence that structures it from within.
