Adam Smith's butcher was not human

Adam Smith famously said that he “does not expect his dinner from the butcher benevolence but from his regard to his own interest”.
On saying so, he is opposing two major human drivers: our love for ourselves and our love for others. With this, he consecrated a false anthropology as the basis for economic science.
But, as ecology and evolutionary biology have most recently taught us, our interest for ourselves and our interest for others are part of a continuum to ensure the Evolution, and maximize the deployment of Nature. No oposition, but complementarity.
Based on a false anthropology, no wonder Economics can bear no real fruit.
