Abstract

In this study, the philosophical and modern problems that arise in the fields of ontology and epistemology within the framework of Descartes' method are studied and investigated. There is an extensive literature on Cartesian philosophy. Homo sapiens refers to the type of people who can think and can collaborate and collaborate with many members. Homo cogitans means the kind of person who can think again but thinking here is not just thinking. We are talking about a species that thinks how it thinks and prioritizes its own thoughts and good sense. Our aim here is to study the journey of a man from Homo sapiens to homo cogitans. We investigated and analyzed the answers to many questions such as what the effects of Cartesian philosophy are today, how Descartes' methodical suspicion led us to individualism.
