The left is stuck in the middle of nowhere on the subject of evolution: it is of vital importance to the contrary that the left be ultra-sophisticated on the subject. At this point it can’t even handle a simple critique of darwinism, and is unable to carry out the critique of ideology that lards the oversimplification of darwinism.
The Darwin debate is beset with the attacks of the religious right, in two forms: the creationists and the Intelligent Design faction. The latter has taken the exposes of darwinism and run with them. The left and the world of science are terrified of the design argument. But what’s the difference. No amount of hardcore darwinism is going to convince the right here (which plays both sides of the fence with its concealed social darwinism), while the issue of design as such is simple to deal with: noone can prove anything, so what is the difference? It if unfair to say that design is not science and then turn around and proclaim the phony claims for natural selection are scientific.
The left has to be able to steward a new evolution of man. But as things stand now, noone on the left could be trusted with any part of that.
