Cary writes that the problem for atheists and agnostics is that they cannot find "objective justification to say that a conflicting ethical code is ethically inferior or wrong." - Perhaps it's worth pointing out that theists have a similar problem. Although Jews, Christians and Muslims have what they believe to be the Word of God (the Bible, the Koran) as an objectively existing reference, texts only come into operation through subjective interpretation. That is why there is no consensus between religions - or sometimes between subdivisions of individual religions - on such matters as abortion, homosexuality, contraception, the role of women, or even the sanctity of life.
