We now understand that the mind is not, as Descartes confusedly supposed, in communication with the brain in some miraculous way; it is the brain, or more specifically, a system of organization within the the brain that has evolved in much the way that our immune system or respiratory system or digestive systems has evolved. Like many other natural wonders, the human mind is something of a bag of tricks, cobbled together over the eons by the foresightless process of evolution by natural selection.
