Abstract

The author emphasize the fact, that the world of really existing compound and distinct things leads to the first questions in our spontaneous cognition of the world, such as: "What is it?", "What for?" Spontaneous cognition thus means the primary, direct experience of the real world, which is the basis of common sense. From common sense arise the first fundamental principles of thought and knowledge, such as "For that, what is, it is impossible not to be", expressed in natural language. Although the designations and functions of the natural language are manifold, the rules of its real meanings are determined by the reality itself. All this pre-scientific, spontaneous cognition enters philosophy, being a necessary and sufficient starting point for the epistemological realism, which offers the way leading to the know_ledge of the real world. The common sense knowledge, based on natural language, prevents the philosophical knowledge from apriori formulations in interpretation of reality. The realistic philosophy thus must meet the natural needs of human know_ledge. This can be achieved through developing the common sense knowledge in the frame of realistic knowledge
