Eventually the old ideas will no longer serve, the old ideological framework can no longer be tinkered up to bear the weight of the facts, and a radical reconstruction becomes necessary, leading eventually to the emergence of a quite new organisation of thought and belief, just as the emergence of new types of bodily organization was necessary to achieve biological advance. Such major organizations of thought may be necessary in science as much as in religion. The classical example, of course, was the re-patterning of cosmological thought which demoted the earth from its central position and led to the replacement of the geocentric pattern of thought by a heliocentric one. I believe that an equally drastic reorganization of our pattern of religious thought is now becoming necessary, from a god-centered to an evolutionary-centered pattern.
