ABSTRACT
“Darwin revolutionized our study of nature by taking the actual variation among actual things as central to the reality, not as an annoying disturbance to be wished away. That revolution is not yet completed. Biology remains in many ways obdurately Platonic. … (For example,) Neurobiologists want to know how the brain works, but they don't say whose brain. Presumably when you've seen one brain you have seen them all” (Lewontin, 1983).
