Christopher Hitchens - The Portable Atheist - Essential Readings for the Nonbeliever

How could we stop ourselves from indulging in murder, rape, theft, perjury, and genocide if we believed the heavens were empty? The question is posed upside-down and inside out and wrong-way round, as this elegant and tough-minded essay confirms.

At the Institute for Creation Research Museum in Santee, California, visitors begin their tour by viewing a plaque displaying the “tree of evolutionism,” which, it is said (following Matt. 7:18), “bears only corrupt fruits.” The “evil tree” of evolution is a stock metaphor among proponents of the literal truth of the biblical story of creation. In different versions, it represents evolutionary theory as leading to abortion, suicide, homosexuality, the drug culture, hard rock, alcohol, “dirty books,” sex education, alcoholism, crime, government regulation, inflation, racism, Nazism, communism, terrorism, socialism, moral relativism, secularism, feminism, and humanism, among other phenomena regarded as evil. The roots of the evil tree grow in the soil of “unbelief,” which nourishes the tree with “sin.” The base of its trunk represents “no God”—that is, atheism.

The evil tree vividly displays two important ideas. First, the fundamental religious objection to the theory of evolution is not scientific but moral. Evolutionary theory must be opposed because it leads to rampant immorality, on both the personal and political scales. Second, the basic cause of this immorality is atheism. Evolutionary theory bears corrupt fruit because it is rooted in denial of the existence of God.

Most forms of theism today are reconciled to the truth of evolutionary theory. But the idea of the evil tree still accurately depicts a core objection to atheism. Few people of religious faith object to atheism because they think the evidence for the existence of God is compelling to any rational inquirer. Most of the faithful haven’t considered the evidence for the existence of God in a spirit of rational inquiry—that is, with openness to the possibility that the evidence goes against their faith. Rather, I believe that people object to atheism because they think that without God, morality is impossible. In the famous words (mis) attributed to Dostoyevsky, “If God is dead, then everything is permitted.” Or, in the less-famous words of Senator Joe Lieberman, we must not suppose “that morality can be maintained without religion.”

Why think that religion is necessary for morality? It might be thought that people wouldn’t know the difference between right and wrong if God did not reveal it to them. But that can’t be right. Every society, whether or not it was founded on theism, has acknowledged the basic principles of morality, excluding religious observance, which are laid down in the Ten Commandments. Every stable society punishes murder, theft, and bearing false witness; teaches children to honor their parents; and condemns envy of one’s neighbor’s possessions, at least when such envy leads one to treat one’s neighbors badly. People figured out these rules long before they were exposed to any of the major monotheistic religions. This fact suggests that moral knowledge springs not from revelation but from people’s experiences in living together, in which they have learned that they must adjust their own conduct in light of others’ claims.

Perhaps, then, the idea that religion is necessary for morality means that people wouldn’t care about the difference between right and wrong if God did not promise salvation for good behavior and threaten damnation for bad behavior. On this view, people must be goaded into behaving morally through divine sanction. But this can’t be right, either. People have many motives, such as love, a sense of honor, and respect for others, that motivate moral behavior. Pagan societies have not been noticeably more immoral than theistic ones. In any event, most theistic doctrines repudiate the divine sanction theory of the motive to be moral. Judaism places little emphasis on hell. Christianity today is dominated by two rival doctrines of salvation. One says that the belief that Jesus is one’s savior is the one thing necessary for salvation. The other says that salvation is a free gift from God that cannot be earned by anything a person may do or believe. Both doctrines are inconsistent with the use of heaven and hell as incentives to morality.

A better interpretation of the claim that religion is necessary for morality is that there wouldn ’t be a difference between right and wrong if God did not make it so. Nothing would really be morally required or prohibited, so everything would be permitted. William Lane Craig, one of the leading popular defenders of Christianity, advances this view. Think of it in terms of the authority of moral rules. Suppose a person or group proposes a moral rule—say, against murder. What would give this rule authority over those who disagree with it? Craig argues that, in the absence of God, nothing would. Without God, moral disputes reduce to mere disputes over subjective preferences. There would be no right or wrong answer. Since no individual has any inherent authority over another, each would be free to act on his or her own taste. To get authoritative moral rules, we need an authoritative commander. Only God fills that role. So, the moral rules get their authority, their capacity to obligate us, from the fact that God commands them.

Sophisticates will tell you that this moralistic reasoning against atheism is illogical. They say that whether God exists depends wholly on the factual evidence, not on the moral implications of God’s existence. Do not believe them. We know the basic moral rules—that it is wrong to engage in murder, plunder, rape, and torture, to brutally punish people for the wrongs of others or for blameless error, to enslave others, to engage in ethnic cleansing and genocide—with greater confidence than we know any conclusions drawn from elaborate factual or logical reasoning. If you find a train of reasoning that leads to the conclusion that everything, or even just these things, is permitted, this is a good reason for you to reject it. Call this “the moralistic argument.” So, if it is true that atheism entails that everything is permitted, this is a strong reason to reject atheism.

While I accept the general form of the moralistic argument, I think it applies more forcefully to theism than to atheism. This objection is as old as philosophy. Plato, the first systematic philosopher, raised it against divine command theories of morality in the fifth century BCE. He asked divine-command moralists: are actions right because God commands them, or does God command them because they are right? If the latter is true, then actions are right independent of whether God commands them, and God is not needed to underwrite the authority of morality. But if the former is true, then God could make any action right simply by willing it or by ordering others to do it. This establishes that, if the authority of morality depends on God’s will, then, in principle, anything is permitted.

This argument is not decisive against theism, considered as a purely philosophical idea. Theists reply that because God is necessarily good, He would never do anything morally reprehensible Himself, nor command us to perform heinous acts. The argument is better applied to the purported evidence for theism. I shall argue that if we take the evidence for theism with utmost seriousness, we will find ourselves committed to the proposition that the most heinous acts are permitted. Since we know that these acts are not morally permitted, we must therefore doubt the evidence for theism.

Now “theism” is a pretty big idea, and the lines of evidence taken to support one or another form of it are various. So I need to say more about theism and the evidence for it. By “theism” I mean belief in the God of Scripture. This is the God of the Old and New Testaments and the Koran—the God of Judaism, Christianity, and Islam. It is also the God of any other religion that accepts one or more of these texts as containing divine revelation, such as the Mormon Church, the Unification Church, and Jehovah’s Witnesses. God, as represented in Scripture, has plans for human beings and intervenes in history to realize those plans. God has a moral relationship to human beings and tells humans how to live. By focusing on theism in the Scriptural sense, I narrow my focus in two ways. First, my argument doesn’t immediately address polytheism or paganism, as is found, for example, in the religions of Zeus and Baal, Hinduism, Wicca. (I’ll argue later that, since the evidence for polytheism is on a par with the evidence for theism, any argument that undermines the latter undermines the former.) Second, my argument doesn’t immediately address deism, the philosophical idea of God as a first cause of the universe, who lays down the laws of nature and then lets them run like clockwork, indifferent to the fate of the people subject to them.
