As CrossExamined.org conducts seminars and debates on college campuses, we owe much to Dr. William Lane Craig.  Dr. Craig is one of Christianity’s best intellectual defenders.  He is the author of several Christian apologetics books and scholarly articles, and has debated topics such as the existence of God, the problem of evil, the reliability of the Bible, and several other questions.

Dr. Craig is now posting answers to difficult questions on his web site. You can find them here (at this writing, there are 63 such questions).  You owe it to yourself to learn Christian apologetics from this fine scholar and gentleman.

The following is from Christian Philosopher William Lane Craig’s recent article “God is not Dead Yet” in Christianity Today.   I encourage you to read the entire article.  I include this section on the moral argument because of our recent discussion here about how the existence of objective morality requires God– a claim that atheists have yet to refute.

The moral argument. A number of ethicists, such as Robert Adams, William Alston, Mark Linville, Paul Copan, John Hare, Stephen Evans, and others have defended “divine command” theories of ethics, which support various moral arguments for God’s existence.

One such argument:

1. If God does not exist, objective moral values and duties do not exist.
2. Objective moral values and duties do exist.
3. Therefore, God exists.

By objective values and duties, one means values and duties that are valid and binding independent of human opinion. A good many atheists and theists alike concur with premise (1). For given a naturalistic worldview, human beings are just animals, and activity that we count as murder, torture, and rape is natural and morally neutral in the animal kingdom. Moreover, if there is no one to command or prohibit certain actions, how can we have moral obligations or prohibitions?

Premise (2) might seem more disputable, but it will probably come as a surprise to most laypeople to learn that (2) is widely accepted among philosophers. For any argument against objective morals will tend to be based on premises that are less evident than the reality of moral values themselves, as apprehended in our moral experience. Most philosophers therefore do recognize objective moral distinctions.

Nontheists will typically counter the moral argument with a dilemma: Is something good because God wills it, or does God will something because it is good? The first alternative makes good and evil arbitrary, whereas the second makes the good independent of God. Fortunately, the dilemma is a false one. Theists have traditionally taken a third alternative: God wills something because he is good. That is to say, what Plato called “the Good” is the moral nature of God himself. God is by nature loving, kind, impartial, and so on. He is the paradigm of goodness. Therefore, the good is not independent of God.

Moreover, God’s commandments are a necessary expression of his nature. His commands to us are therefore not arbitrary but are necessary reflections of his character. This gives us an adequate foundation for the affirmation of objective moral values and duties.

Some atheists, such as Richard Dawkins and Christopher Hitchens, insist that morality is simply the product of evolution.  Common moral sensibilities (Don’t murder, rape, steal, etc.) help ensure our evolutionary survival.  There are number of problems with this view:

  1. Rape may enhance the survival of the species, but does that make rape good?  Should we rape?
  2. Killing the weak and handicapped may help improve the species and its survival (Hitler’s plan).  Does that mean the Holocaust was a good thing?
  3. Evolution provides no stable foundation for morality.  If evolution is the source of morality, then what’s to stop morals from evolving (changing) to the point that one day rape, theft and murder are considered moral?
  4. Dawkins and Hitchens confuse epistemology with ontology (how we know something exists with that and what exists).  So even if natural selection or some other chemical process is responsible for us knowing right from wrong, that would not explain why something is right or wrong.  How does a chemical process (natural selection) yield an immaterial moral law?  And why does anyone have a moral obligation to obey a chemical process?  You only have a moral obligation to obey an ultimate personal being (God) who has the authority to put moral obligations on you.  You don’t have a moral obligation to chemistry.

As I mentioned in an earlier post (Atheists Have No Basis for Morality), several atheists at a recent I Don’t Have Enough Faith to Be an Atheist event at UNC Wilmington struggled greatly when I asked them to offer some objective basis for morality from their atheistic worldview.  They kept trying to give tests for how we know something is moral rather than why something is moral.  One atheist said “not harming people” is the standard.  But why is harming people wrong if there is no God?  And what if harming people enhances your survival and that of most others?

Another said, “happiness” is the basis for morality.  After I asked him, “Happiness according to who, Mother Teresa or Hitler?,”  he said, “I need to think about this more,” and then sat down.  This says nothing about the intelligence of these people– there just is no good answer to the question.   Without God there is no basis for objective morals.  It’s just Mother Teresa’s opinion against Hitler’s.
