In Dostoyevsky’s classic, The Brothers Karamazov, Ivan Karamazov, the Russian author’s symbol for the scientific, rational, Western outlook, wrestles with the problem in the title of this article; without God, everything is permitted. Since then, this proposition has been used in countless discussions to justify belief in (typically the Christian) God. At least a part of its appeal for the religiously inclined lies in the near instant assent it tends to evoke. If there is no God, and therefore no higher Authority to dictate to us what our ethical rights and obligations are, how can we have any? We need God to ground morality. In this article, I will challenge this claim.
