Some different ways to think
Abstract
Daniel Dennett has offered a helpful framework in which to consider the evolution of mind, calling it "the tower of generate and test". On the bottom of the tower there are "Darwinian creatures," whose patterns of behavior result from the effects of natural selection alone. Next come "Skinnerian creatures," whose behaviors continue to be modified during their individual lifetimes by trial, reward and punishment. Third are "Popperian creatures," capable of learning, as well, by trying things out in their heads. Last are "Gregorian creatures," who learn through interaction with culture. I have spent some time trying to construct a similarly broad and rough framework in which to consider the evolution of mind, but focused on the development of inner representational systems. The idea was to explore possible forms of representation first within perception and then within thought as it becomes freed from perception. As I progressed, however, this fairly simply conceived project was soon out of hand. At times I thought I must be trying to reconstruct Kant 's.
