In 2011, author and neuroscientist Sam Harris debated evangelical Christian apologist William Lane Craig on the topic of morality and god entitled, “Is Good From God?” The debate, largely was an attempt by Dr. Craig to critique Dr. Harris’ book The Moral Landscape: How Science Can Determine Human Values. As you may know, I have a bone to pick with Dr. Craig regarding his attempts to rationalize the more troubling aspects of his Christian faith, and in the debate he offers several examples which I will criticize.
Dr. Craig opens the debate with his two primary contentions. First, that if god exists, he offers a sound foundation for the existence of objective morals and duties, and second, that if god does not exist, then we do not have a sound foundation for objective moral duties and values. Dr. Craig defines “objective” morality as being valid and binding, independently of human opinion. Both Dr. Craig and Dr. Harris assert the existence of objective morals and duties, and only disagree with what is its foundation. On my blog, I have written repeatedly about how I believe there is exists a certain core of values that are objectively true, and are not relative to anyone’s opinion. And I have argued against the idea that the existence of god is what these objective values are founded in. What I want to do is critique line by line, the objections that Dr. Craig makes against Dr. Harris’ argument that science can offer us a foundation for objective values.
Right off the bat in Dr. Craig’s opening remarks he asserts the ontological foundation for goodness:
11:20 On the theistic view objective moral values are grounded in God. As St. Anselm saw, God is by definition the greatest conceivable being and therefore the highest Good. Indeed, He is not merely perfectly good, He is the locus and paradigm of moral value. God’s own holy and loving nature provides the absolute standard against which all actions are measured. He is by nature loving, generous, faithful, kind, and so forth. Thus if God exists, objective moral values exist, wholly independent of human beings.
One of the problems I have with this statement is the fact that the greatest conceivable being is a highly subjective expression. For example, Muslims and Christians have distinct beliefs on the nature of god. Muslims disagree with Christians that god had to rest on the seventh day after he created the universe because resting is not a property of an omnipotent god. If a god who needs to rest is less great than a god who doesn’t, than it follows that the Muslim concept of god may be better than the Christian concept. So a greatest conceivable being to a Muslims, is different than that of a Christian. And what if a psychopath’s idea of the greatest conceivable being would be that of a sadistic dictator? Could the greatest conceivable being then an aggregation of all these diverse concepts by taking the best from each? God’s nature consists of many things and jealousy is one of them. He is also wrathful, and capricious. Are these the characteristics of greatness?
