The term ‘Morality of Evolution’ occupies a distinctive position in the depth-psychology corpus, functioning simultaneously as a structural category, a therapeutic aspiration, and a philosophical challenge to fixed ethical systems. Its most explicit instantiation appears as the introductory rubric to Karen Horney’s Neurosis and Human Growth (1950), where it frames her entire clinical argument: psychological growth toward self-realization is itself the moral criterion, displacing static codes of duty with a dynamic, developmental standard. This Horneyian formulation resonates with Erich Neumann’s demand, in Depth Psychology and a New Ethic (1949), that depth psychology requires an ethics adequate to the shadow—one that transcends the ‘old ethic’ of collective moral repression. The evolutionary dimension is enriched by Alexander’s reading of Darwin, who grounds the moral sense not in commandment but in the pleasurable satisfaction of social instincts, anticipating the naturalistic and integrative ethics that recurs across the corpus. Stoic antecedents, examined by Inwood, trace this trajectory to ancient accounts of moral development from birth toward a love of reason. Aurobindo extends the frame cosmically, positing moral evolution as a spiritual necessity intrinsic to the soul’s progressive unfoldment. Against all these integrative and progressive readings, Nietzsche’s genealogical challenge stands as the permanent counterpoint, refusing any teleological comfort while insisting that truthfulness is itself the highest moral evolutionary achievement.
