ABSTRACT
This chapter aims to develop the intuition into an idea about the activity of an organ of the body, because evolutionary biology is about organic evolution, and the evolutionary biology of mind must be about the organic basis of mind. Darwinism has traditionally been a doctrine about phyletic history, about the origin and change of species. The chapter reviews the nature of mind from a perspective that lends itself to evolutionary analysis. That perspective emphasizes a role for perceptual-motor and cognitive integration. The chapter discusses the hierarchical organization of very large nervous systems in effecting the integration. It also reviews the evolution of mind as the history of encephalization – the history of the enlargement of the brain beyond the grade expected from trends towards the evolution of larger bodies. The chapter compares anagenetic with cladistic evolution in order to put the evolution of mind into an appropriate evolutionary perspective.
