Alfred Russel Wallace, the codiscoverer of the theory of natural selection. Following their twin announcements of the theory in 1858, both Darwin and Wallace struggled like Laocoöns with the serpentine problem of human evolution and its encoiling difficulty of consciousness. But where Darwin clouded the problem with his own naivete, seeing only continuity in evolution, Wallace could not do so.

The changes in the Catholic Church since Vatican II can certainly be scanned in terms of this long retreat from the sacred which has followed the inception of consciousness into the human species.

Memory is the medium of the must-have-been.

The bicameral mind with its controlling gods was evolved as a final stage of the evolution of language. And in this development lies the origin of civilization.

Poetry, from describing external events objectively, is becoming subjectified into a poetry of personal conscious expression.

The language of men was involved with only one hemisphere in order to leave the other free for the language of the gods.

This breakdown in the bicameral mind in what is called the Intermediate Period is reminiscent at least of those periodic breakdowns of Mayan civilizations when all authority suddenly collapsed, and the population melted back into tribal living in the jungles.
