Theories and practices of social scientists in relation to cultural change are described and evaluated. The first section considers psychology's emerging ethics, reviewing the work of Maslow, Fromm, and Money-Kyrle. Part II presents and considers some claims that specific cultures are maladaptive or sick, according to varying standards, and Part III discusses ethical and practical issues involved in intervention at a cultural level. The final section presents some models of cultural therapy, some analogies between individual and cultural therapy, and a personal approach. The models considered include psychoanalytic cultural therapy, behavior modification cultural therapy, and existential cultural therapy. The personal approach is integrative or eclectic. (LH)
