 Humans cannot free themselves from nature 
This article is a review of Cyrille Barrette’s book La vraie nature de la bête humaine, published by Éditions MultiMondes. This ethologist presents his conception of a dual nature in our species, an animal nature and a strictly human nature, based on the idea that humans have completely freed themselves from the grip of natural selection. Three conclusions emerge from our analysis. The first is that natural selection is still going on. The second conclusion is that we have a single nature resulting from both biological evolution and culture. Finally, we disagree with his idea that many human activities are unnatural because, according to him, they result from creations of the individual and collective mind of our species, and because he considers them to be useless or harmful in terms of survival and reproduction. How do humans think they can cope with the problems of the destruction of the biosphere if they define themselves as being outside nature?
