Freud's concept of "drive" or "instinct" ("Trieb") has been widely acknowledged as one of the most fundamental concepts of psychoanalysis. However, its meaning is still a matter of controversy. It was originally defined by Freud in a biological or quasi-biological sense, but its reception in many different post-Freudian traditions has often tended to reject this early epistemological affiliation. One sign of this theoretical reorientation has been to refuse the translation of "Trieb" as "instinct" and to favor instead the neologism "pulsion" ("drive"), which has French origins and became common in the psychoanalytic literature written in many neo-Latin languages, including Portuguese. The objective of this paper is to criticize this trend. For that, the main arguments usually presented against a biological view of Freud's "Trieb" are discussed, namely: (1) the terminological alternative between the German words "Trieb" and "Instinkt" and how these terms are employed by Freud; (2) Freud's critique of the reduction of human sexuality to the reproductive function; (3) the concept of "Todestrieb" ("death instinct" or "death drive"), formulated by Freud around 1920 and central in the last stage of his thought. It is argued that these formulations do not preclude a biological interpretation of the concept of "Trieb". Such interpretation, in turn, opens the way for dialogue between psychoanalysis and biology, a dialogue which was also emphatically and explicitly supported by Freud. This first part of the paper is an introduction to this issue, and approaches the problem of the relationship between sexuality and reproduction in psychoanalysis and biology. A second part will be published in a forthcoming issue of Scientiae Studia; it will be dedicated to the problem of aggression and self-destructiveness in these two fields of knowledge.
