In his Presidential Address to the Anglican Consultative Council, meeting in Dundee at this time, the Archbishop of Canterbury expressed his disagreement with my new book Godless Morality. This did not surprise me. The Archbishop and I come from very different theological traditions, though we always try to express any disagreements we may have with one another as amicably as possible. In any case, disagreement is central to the search for truth in complex areas, such as theology and ethics. I do not wish to offer a major response to the Archbishop's criticism of my book, but I would point out that he did not answer the main question the book struggles with: how can we negotiate necessary change to our ethical systems if we continue to associate them exclusively with God?
