Maurice Merleau-Ponty (1908-1961) - the famous philosopher of the 20th century, author of the works "Phenomenology of Perception" (1945), "Meaning and Nonsense" (1948), "Visible and Invisible" (1964), etc. In the present book, Merlo-Ponti seeks the answer to the question: "What kind of philosophy?" The author considers the first task of philosophy to be the desire for a new, unknown. In his studies, the philosopher relies on the ontological teaching of Lavelle, Bergson's intuitionism, the concept of Le Roy's "ingenuity," Marx's "historical rationalism," Montaigne's "skepticism," analyzes the idea of ​ ​ Husserl's intersubjectivity, the concepts of social anthropology of Moss and Levi-Sgross, Machiavelli's political views, then entering into productive dialogue, then sharply polemicizing with them.
