Abstract

The depth and spread of Descartes’ philosophical thoughts, he man transferred from the Renaissance to the modern period to the Modern ages, made it possible for the contemporary and later philosophers to interpret, analyze and criticize them. Descartes called his knowledge tree, the undoubted foundation as “I” or “thinking thing” (Res Cogitans); then, based on that, he proved the body or the outer world, God and other sciences. Heidegger considered such a thing by Descartes as meaning the separation of subject and object, something he did not believe in himself. By introducing the interrogator nature of the human being, which he calls Dasein or “being-in-the-world” or “existence-there” nature of humans, he rejected the subjectivity and objectivity separation, and criticized the foundation of Descartes’ philosophical thoughts. He considered Descartes’ ontology as the continuance of the ontology in the Middle Ages and criticized it. Through consideration of Heidegger’s well-known book, “Existence and Time”, the present paper distinguishes his five main Onticol-Ontological criticisms on Descartes’ philosophy and investigates them.
