For millions of years, the part of the galaxy containing our solar system has been moving through a vast force field whose effect has been to inhibit "certain electromagnetic and electrochemical processes" and thus certain neurotic functions.

A transcendent look at the possible effects of enhanced intelligence on our planet.
