It is by metaphor that language grows. - Julian Jaynes

It is not always obvious that metaphor has played this all-important function. But this is because the concrete metaphiers become hidden in phonemic change, leaving the words to exist on their own. Even such an unmetaphorical-sounding word as the verb 'to be' was generated from a metaphor. It comes from the Sanskrit bhu, “to grow, or make grow,” while the English forms 'am' and 'is' have evolved from the same root as the Sanskrit asmi, “to breathe.” It is something of a lovely surprise that the irregular conjugation of our most nondescript verb is thus a record of a time when man had no independent word for 'existence' and could only say that something 'grows' or that it “breathes.”

"What is the meaning of life?" This question has no answer except in the history of how it came to be asked. There is no answer because words have meaning, not life or persons or the universe itself. Our search for certainty rests in our attempts at understanding the history of all individual selves and all civilizations. Beyond that, there is only awe.

The vestiges of the bicameral mind do not exist in any empty psychological space.
