This commentary on Wright & Panksepp explores the implications of the functions of the SEEKING system for the psychoanalytic theory of aggression and libido as basic drives. It proposes that, in contrast to the temptation to relate the SEEKING system to Freud's libido drive, it should be understood that the SEEKING system is a basic drive that couples with both rewarding and aversive affective systems, and that Freud's dual-drive system may better be understood as a “tertiary” motivational system—that is, a hierarchically supraordinate integration, respectively, of positive- and negative-affect systems. Libido and aggression, thus conceived, would operate as an ultimate system at a symbolic, experiential level, in contrast to the organization of basic affective drives at a neurobiological level. The need to explore motivational systems both at a neurobiological level and at a derived, symbolic level is illustrated with the examples of addiction and depression, referred to in Wright & Panksepp's article.
