Abstract

The understanding of value in moral naturalism as a descriptivist endeavor will be analized through an application of the naturalistic fallacy on an evolutive perspective of moral psychology. From a brief analysis of the naturalistic fallacy as proposed by Dall’Agnol, I’ll criticize the author’s application of such on what he refers to as moral naturalism. Contrasting E. Wilson’s sociobiology with R. Triver’s theory of reciprocal altruism I will procure a definition of naturalized ethics by investigating the psychological roots of moral motivation. Once identified the descriptive and non-reductionist aspects of contemporary moral naturalism, the naturalistic fallacy presents itself as unbecoming of its hallmark and metaethical importance, and it becomes clear that a naturalized comprehension of human moral behavior is vital to the understanding of the motivations for action and the conception of value; though weak under a normative perspective.
