Nerlich argues that normal human animals are naturally endowed with certain attributes for being persons, speakers of an articulate language living in a culture. Language and cultural life require self-appraisal, and hence an evolution, through self-conflict, of desires into values. Thus valuing is seen as a natural process for persons, one which underlies the morals of duty and obligation. Valuing will be good only if it results in values which are authentic to the individual's nature and to the surrounding culture, and which are objective.
