In this paper we will discuss the subject’s causation from the concepts of “alienation” and “partition” in a Lacanian perspective, drawing upon the analysis of a clinical case of the recent psychoanalytic literature. It is delimited, in the article, the theme of someone choices from the Other significant determinations, considering “alienation” as the former and the most original operation that rescues the human being, serving him as a matrix. Then, we emphasize “partition” as a logical moment in which the subject produces something particular through the significant that comes from this same other. Some data of a clinical case, where the treatment direction presented, in a paradigmatic way, these two logical moments, give clinical highlight to our discussion.
