ABSTRACT
Every theory of the mind is a more or less successful attempt, made by the conscious psyche, to describe the undescribable by definition: the psychic process. Nevertheless, the immediate consequence of a theory of the mind is to define what is possible and what is not possible within a psychotherapeutic journey. Drawing the lines of a theory, thus, a theorist should remember to use pencil and eraser, so to say, in order to look back on what he or she has drawn and correct it. Because defining what is possible and what is not, what is normality and what is pathology, is equal to stating what is “right” and what is “wrong”. Ethics must be clearly present in the mind of the theorist, because practical consequences of a theory have an immediate impact on the ethic dimension. A particularly rigid theory is thus in serious danger to break this dimension.
