The new point of view to the comparative estimate of truth, use and preference of natural science conceptions is discussed. Any conception as a model of reality can be by definition neither true nor false absolutely. Any empiric fact can neither corroborate nor disprove any conception entirely. A strict estimate of a degree of correspondence to the facts is impossible. One or another conception is a more useful one owing not to aforesaid, but to the most efficiency of application to solution of scientific and practical problems only.
