Abstract

Charles Darwin’s theory of species evolution by means of natural selection is known largely because of the impact it had on biology and other natural sciences in general; this is hardly a surprising fact. Thus, it could strike certain readers –those accustomed to a philosophical discourse– as odd to speak of “Darwinian ethics.” However, Darwin’s theory of evolution has not been unknown to other areas and disciplines of thought, philosophy among them. Just as with other ‘destroyers’ of the ideas present in their time –such as Nietzsche or Freud–, the impact of Darwin’s thought was felt as a deadly blow to some of the staple ideas and suppositions he weld concerning human life, nature and our place in it. Therefore, it is certainly relevant to discuss, as philosophers, the possibility of an ethic that is purely based on Darwin’s ideas. With this in mind, what I intend to do in the following article is to offer a brief exposition of Darwinian ethics, its main aspects as well as some of the problems and criticisms it has faced since its inception. It would certainly not be possible to speak of one single approach to Darwinian ethics; on the contrary, the theory has been reviewed and reinterpreted a great number of times, and not only by Darwin himself but also by many subsequent thinkers. Among these new reinterpretations, it has come to my attention the one offered by Darwinian metaethics, and to this approach I personally subscribe. Next I will consider diverse positions regarding the issue of Darwinian ethics, and will try to explain why metaethics offer the correct approach to it.
