This paper regards Seneca's practical philosophy as ancestor to psychoanalytically informed psychotherapy and as a progenitor of ongoing contemporary praxis in applied ideas of mind. Facing forward into the Anthropocene, as psychoanalysis encounters Artificial Intelligence, the convergence with contemporary psychoanalytic psychotherapy of value concepts developed from Antiquity is discussed. Drawn from Seneca's Letters on Ethics, constellations of significant ideas present in ancient practical philosophy resonate with similar configurations developed two millennia later, and central to the practice of contemporary psychotherapy.
