Jacques Lacan kept silent on the topic of social psychology, never referring to it, not even to criticize it. But this has not impeded Lacanian theory from inspiring diverse critical approaches to social psychology. After reviewing these approaches, the article examines Lacan's different explicit positions with respect to psychology, the social and what he called psychology of the social field. This allows us to infer the implicit manner in which Lacan would establish his silent relationship with social psychology. On the basis of this relationship, we outline an original proposal for a Lacanian critical approach to social psychology that might lead to an alternative transindividual metapsychology. Our proposal precisely differs from others in that it attempts to consider and elucidate Lacan's own attitude regarding social psychology.
