The article describes the text category "image of the author." The author considers the phenomenon of the text as an open system included into a discourse where the source text unit is not equal to the final product, the modeled text. The category “image of the author” is defined within the framework of the concept of the primary and secondary author. The author indicates that a metaphor in scientific discourse actively involves the reader into a dialogue with the researcher, in the process of interpretation of meaning. It is shown that metaphorization is necessary in the modeling of a secondary text as one of the cognitive mechanisms of the "creating" form.
