The Outer Banks of Order
The story of life reads as a widening gyre of complexity and functional organization. This chapter rambles along its margins with the focus on mind, particularly human minds, whose productions are even now transforming the entire biosphere. Mind is not a wholly material phenomenon, but neither is it divorced from matter; and it is quite certainly a product of prolonged evolution. Genes have a role to play, but mental activities grow out of a much higher level of organization, where cells (neurons) rather than genes construct elaborate networks of communication. Just how mind (memory, judgment, feelings) emerges from the firings and couplings of neurons is largely unknown, a topic for continued reflection and debate. It has even been argued that our materialistic conception of the world is altogether false. In the meantime we can usefully consider how the human lineage, the primary carriers of mind, evolved its fateful characteristics. And we can speculate about the cosmos: is it a garden buzzing with exotic creatures, or a sterile desert sprinkled with a few pinpoints of life?
