This article is a reproduction of parts the fourth chapter of the book 'The Return of Icaro, Death and Life of the Philosophy”, that will be published by the Universidad Autonoma de Occidente. The book intend to debate the crossroad in which any environmental interpretation is finned: penned between the reductionism of natural sciences and the philosophical sobrenaturalism of the social science. Between some natural sciences that don't understand the man and some social sciences that don't recognize the bonds with the nature. If this approach is applied to the study of society or of culture, it would be necessary to understand it as the result of a evolutionary process, but also at the same time as a rupture with the previous evolutionary forms.The culture is not in the genes, but it has relationships with nature, the social sciences have not wanted to accept this fact. It has ethical and political consequences. As well as there is no ecosistemic ethics, all human ethics should be aware of its relationships with the environment. Maybe this proposal will bring a new vision of what is freedom.
