Market failure is a favourite phrase; government failure is not. - Matt Ridley

Yet as soon as Greece was unified into an empire by a thug – Philip of Macedon in 338 BC – it lost its edge.

In the 1970s a few brave “sociobiologists” began to ask why, if other animals had evolved natures, humans would be exempt. They were vilified by the social science establishment and told to go back to ant-watching. Yet the question they had asked has not gone away.
The principal reason for the hostility to sociobiology was that it seem to justify prejudice. This was simply a confusion. Genetic theories of racism, or classism or any kind of ism, have nothing in common with the notion that there is a universal, instinctive human nature. Indeed, they are fundamentally opposed because one believes in universals and the other in racial or class particulars.

But as we shall see, the appearance is misleading. Animal altruism is a myth. Even in the most spectacular cases of selflessness it turns out that animals are serving the selfies interests of their own genes—if sometimes being careless with their bodies.
