"The unconscious" of S. Freud and "the set"" of D. N. Uznadze are completely different notions. Uznadze's set is an explanatory theory of the behavior of animals (man included). He assumed that the work of psyche is not restricted to the sphere of consciousness. If so the psyche would oppose the rest of the living world and constitute an independent and completely closed quarter of reality - which excludes the issue of psyche development. It must be put down to Uznadze's credit that he not only recognized existence of psyche "beyond consciousness", but also conceptualized corresponding psychological mechanism under the name of "set".
