Abstract

The paper proves unproductiveness of instrumentalist ideology in interpretation of the nature of scientific concepts and theories. While legitimate on a short distance of science development, it however, inevitably leads on the “long run” of theories to stagnation in science development. The strategy of employing theoretical concepts merely as instruments of predicting new results deprives scientist of a stimulus to emerge “beyond the existing into the sphere of super-existing”. Under “super existing” Heidegger understands metaphysics. The ignoring of “super-existence” blocks the access to the most valuable source of intelligibility of the very existence.
