Such is the fate of many religious and moral values and, in consequence, the passing over to subjectivist positions in the field of human behavior. An important role in evolving the outlook of contemporary culture was played by a current of philosophy called existentialism. It emerged, as it is well known, as a reaction against the Cartesian rationalism, panlogism of Hegel, positivism, scientism and naturalism. It referred to anthropocentrism by emphasizing the concrete, the finished and the paradoxal in the human being. It could be found in different forms.
Philosophy is understood in the existentialism as one of the basic existence ways.
If the condition of contemporary culture is causally linked with such solutions, emerged after as a result of departure from the classic philosophy then, to remedy it, one should return to this philosophy. Prior to indicating reasons for returning to the classic philosophy, it has to be given, in few sentences, a description on how to understand the classic philosophy. Well, this philosophy is understood here as an universal science or knowledge, objectivist and rational, searching for ultimate reasons for the reality being experienced. This type of knowledge is a realistic one. The character of realism is secured for it, generally speaking, when taking into account, in the course of inquiry, actual condition of things and cognitive contact with the existing reality.
