Fernando Oyarzún's La Idea de la Persona Ética (The Idea of Ethic Person) integrates a phenomenological and anthropological approach to psychiatry and an ethical orientation that transcends disciplinary boundaries. These essays claim for the personification of human relations in a world constantly threatened by alienation. Oyarzún's view, while focusing on the relational nature of the person, integrates the moral sources of the self, aiming human redemption through personal, medical and teaching encounters that singularize the person in a context where the ethical assumption is the owing of oneself to the others. From this view is possible to expand the human commitment not only to interpersonal relationships but to the material world in which they are inscribed and to which the specie belongs. Oyarzún's statements are applicable not only to the challenges drawn from depersonalization but to those arising from the depletion of the ecosystem. Thus, the humanist and anthropological thinking of the author might integrate to the contemporary views of the vital materialism.
