Academician S.V. Vonsovsky raised a problem concerning the essence of the philosophy of science. According to S.V. Vonsovsky, theoretical physics has became philosophy in the contemporary intellectual world. Yet he doesn't accept positivist's motivation. On the contrary, he brings us back to ancient Greek conception of the inseparable connection between philosophy and physics, when both were concentrated on φύσις. Theoretical physics is philosophical in a sense that is discovers the underlying nature of all processes and events; without it, it would be impossible to explain and to understand, what is going on in the universe and on the earth, in the world of living creatures and in the human's social world.
Keywords: theoretical physics, philosophy, science, φύσις, picture of the world, philosophy of science.
