A paragraph from Wilkins:
Now I want to note at the outset that there are several kinds of thing that get called sociobiology, according to one's attitude to biological accounts of social behaviour, and the age in which the writers under consideration worked. Few disciplines are as history-ridden as evolutionary biology, and few within that as social biology. I mark out three types of social biology: the standard Evil Demon of eugenics and "social Darwinism" (which is neither social, nor Darwinian, nor ever an actual historical movement, but that's for another day). We may dismiss this as being of no positive value apart from an object lesson in how not to apply science to society. The second is the movement of the 1970s to treat humans as social animals and discuss the ways in which evolution has shaped us. This is the sense of the term in Wilson and Wilson, and which I will discuss below. The third is that same evolutionary psychology. A few short words about that before we begin.
