The very reason we need logic at all is because most reasoning is not conscious at all.

The mind is still haunted with its old unconscious ways; it broods on lost authorities; and the yearning, the deep and hollowing yearning for divine volition and service is with us still.

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.

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.

Reading in the third millennium B.C. may therefore have been a matter of hearing the cuneiform, that is, hallucinating the speech from looking at its picture symbols, rather than visual reading of syllables in our sense.

Our sense of justice depends on our sense of time. Justice is a phenomenon only of consciousness, because time spread out in a spatial succession is its very essence. And this is possible only in a spatial metaphor of time.

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.
