Mark Solms' revision of the concept of drive represents the latest in a series of his indepth reviews of the most fundamental Freudian concepts. The movement of neuropsychoanalysis begun in 2000 with the first Congress focused precisely on a neuroscientific definition of affects and emotions. In 2013, Solms proposed a substantial and profound modification of Freud's structural model, motivating his theses which argue that the instinctual id can only be conscious. In the current paper, Solms (2021a) reaffirms and re-evaluates the centrality of drive theory in psychoanalysis and neuroscience as a starting point for understanding conscious and unconscious phenomena, in normality as well in pathology.
