Abstract

It is known that sociobiology, the theory of the biological origins of the social behavior of living beings, is related to ethics. However, sociobiology does not include moral doctrines but simply describes facts. The present essay discusses two basic theses, “altruism” and “reciprocal altruism”, in order to prove that a natural science free of judgments and evaluations is contrary to a theory of ethics, such as the theory of Kant and Apel, as well as to intuitive theories of ethics. Ethics is the explanatory theory of morality, and morality should be established at the theoretical level, so that doubt can be expressed and not restrained.
