The British writer and philosopher Iris Murdoch once wrote, “It is easy to say there is no God. It is not so easy to believe it and to draw the consequences.” By this she meant that our vision of reality, our understanding of the way the world works, cannot help but influence our moral and political beliefs. Politics is not so easily separated from metaphysics. And questions of metaphysics, it turns out, take us readily into the realm of theology. Whether one recognizes it or not, the position one takes on the question of God’s existence is inevitably linked to one’s position on a host of other moral and political issues.
