What makes you think human beings are sentient and aware? There's no evidence for it. Human beings never think for themselves, they find it too uncomfortable. For the most part, members of our species simply repeat what they are told-and become upset if they are exposed to any different view. The characteristic human trait is not awareness but conformity, and the characteristic result is religious warfare. Other animals fight for territory or food; but, uniquely in the animal kingdom, human beings fight for their 'beliefs.' The reason is that beliefs guide behavior which has evolutionary importance among human beings. But at a time when our behavior may well lead us to extinction, I see no reason to assume we have any awareness at all. We are stubborn, self-destructive conformists. Any other view of our species is just a self-congratulatory delusion. Next question.

My own sense is that the acquisition of self knowledge has been made difficult by the modern world. More and more human beings live in vast urban environments, surrounded by other human beings and the creations of human beings. The natural world, the traditional source of self-awareness, is increasingly absent.

The academic world was marching toward ever more specialized knowledge, expressed in ever more dense jargon.
