The article deals with the semantic theory of thinking worked out by O.K. Tikhomirov which is considered a unique epistemological phenomenon. By means of its development the theory demonstrates the assimilation of three types of scientific rationality beginning with classical type, passing to non- classical and then to post- non- classical. It is stated in the article that the transspective analysis allows the investigator to examine the formation of scientific theory and to reveal the reasons which determine the “paradigm shifts” taking place in psychology and which are connected with the objective tendencies of the development of scientific knowledge. The article shows the real examples of the ways how the theory falsifies itself forcedly producing the facts, which can be explained only by means of the transition to the new level of its system organization. In accordance with the facts mentioned we can observe the rise of the level of professionalpsychological thinking.
