The question now is where we are going. Will the future be an age of new atheistic ideologies? Or of materialistic trade and technology, with the potential for radical transformation of human nature? Or will it be a new religious age with the potential for renewed persecution and compelled conformity?
No path looks ideal. Perhaps the best we can hope for is a creative tension between the religious and the secular, which allows each some freedom, but keeps check on the extremes of both.
The extremes will be checked by violence when treaties break down.
