Morality and religion: intimately wed, violently opposed, or something else? Discussion of this issue appears in pop-culture, the academy, and the media-often generating radically opposed views. At one end of the spectrum are those who think that unless God exists, ethics is unfounded and the moral life is unmotivated. At the other end are those who think that religious belief is unnecessary for-and even a threat to-ethical knowledge and the moral life. This volume provides an accessible, charitable discussion that represents a range of views along this spectrum. The book begins with a lively debate between Paul Kurtz and William Lane Craig on the question, Is goodness without God good enough? Kurtz defends the affirmative position and Craig the negative. Following the debate are new essays by prominent scholars. These essays comment on the debate and advance the broader discussion of religion and morality. The book closes with final responses from Kurtz and Craig.

But it is interesting that the same thing happens to you when you have to give some warrant for trusting in "reason". I noted your citation of LaPlace in your book and am glad you brought him up here. LaPlace believed he was not in need of the God hypothesis, just like you, but you should also know he held this position as a firmbeliever in celestial and terrestrial mechanics. He was a causal determinist, meaning that he believed that every element of the universe in the present was "the effect of its past and the cause of its future."

So if LaPlace is why you think belief in God is now "optional," this appeal of yours actually turns into quite a fun business. This doctrine means [...] that you, Christopher Hitchens, are not thinking your thoughts and writing them down because they are true, but rather because the position and velocity of all the atoms in the universe one hundred years ago necessitated it. And I am not sitting here thinking my Christian thoughts because they are the truth of God, but rather because that is what these assembled chemicals in my head always do in this condition and at this temperature. "LaPlace's demon" could have calculated and predicted your arguments (and word count) a century ago in just the same way that he could have calculated the water levels of the puddles in my driveway — and could have done so using the same formulae. This means that your arguments and my puddles are actually the same kind of thing. They are on the same level, so to speak.

If you were to take a bottle of Mountain Dew and another of Dr. Pepper, shake them vigorously, and put them on a table, it would not occur to anyone to ask which one is "winning the debate." They aren't debating; they are just fizzing. You refer to "language in which to write this argument," and you do so as though you believed in a universe where argument was a meaningful concept. Argument? Argument? I have no need for your "argument hypothesis." Just matter in motion, man.

Hitchens, one of our great political pugilists, delivers the best of the recent rash of atheist manifestos. The same contrarian spirit that makes him delightful reading as a political commentator, even (or especially) when he's completely wrong, makes him an entertaining huckster prosecutor once he has God placed in the dock. And can he turn a phrase!: "monotheistic religion is a plagiarism of a plagiarism of a hearsay of a hearsay, of an illusion of an illusion, extending all the way back to a fabrication of a few nonevents." Hitchens's one-liners bear the marks of considerable sparring practice with believers. Yet few believers will recognize themselves as Hitchens associates all of them for all time with the worst of history's theocratic and inquisitional moments. All the same, this is salutary reading as a means of culling believers' weaker arguments: that faith offers comfort (false comfort is none at all), or has provided a historical hedge against fascism (it mostly hasn't), or that "Eastern" religions are better (nope). The book's real strength is Hitchens's on-the-ground glimpses of religion's worst face in various war zones and isolated despotic regimes. But its weakness is its almost fanatical insistence that religion poisons "everything," which tips over into barely disguised misanthropy. ~ Publisher's Weekly

Theists frequently argue that nontheists must affirm the following: (1) If there is no God, each person must define "good" and "evil" for herself. (2) If each person must define "good" and "evil" for herself, there can be no objective moral standard. (3) God does not exist. (4) Therefore there can be no objective moral standard (i.e., all moral principles are relative). Some nontheists agree (e.g., Sartre) and attempt to live with the implications of (4). Others deny (2), claiming that the existence of an objective moral standard is not dependent on religious commitment. Kai Nielsen is one of the best known and most outspoken members of this group. Nielsen argued that "the nonexistence of God does not preclude the possibility of there being an objective standard on which to base [moral] judgments." He has recently reaffirmed this claim:

An Introduction to Contemporary Metaethics provides a highly readable critical overview of the main arguments and themes in twentieth-century and contemporary metaethics. It traces the development of contemporary debates in metaethics from their beginnings in the work of G. E. Moore up to the most recent arguments between naturalism and non-naturalism, cognitivism and non-cognitivism.

Despite the pluralism of contemporary American culture, the Judaeo-Christian legacy still has a great deal of influence on the popular imagination. Thus it is not surprising that in this context atheism has a slightly scandalous ring, and unbelief is often associated with the lack of morality and a meaningless existence. Distinguished philosopher and committed atheist Michael Martin sets out to refute such notions in this thorough defense of atheism as both a moral and a meaningful philosophy of life. Martin shows not only that objective morality and a purposeful life are possible without belief in God but also that the predominantly Christian worldview of American society is seriously flawed as the basis of morality and meaning.

Four principal papers and a total of 43 peer commentaries on the evolutionary origins of morality. To what extent is human morality the outcome of a continuous development from motives, emotions and social behaviour found in nonhuman animals? Jerome Kagan, Hans Kummer, Peter Railton and others discuss the first principal paper by primatologists Jessica Flack and Frans de Waal. The second paper, by cultural anthropologist Christopher Boehm, synthesizes social science and biological evidence to support his theory of how our hominid ancestors became moral. In the third paper philosopher Elliott Sober and evolutionary biologist David Sloan Wilson argue that an evolutionary understanding of human nature allows sacrifice for others and ultimate desires for another's good. Finally Brian Skyrms argues that game theory based on adaptive dynamics must join the social scientist?¢‚Ǩ‚Ñ¢s use of rational choice and classical game theory to explain cooperation.

This book shows how Darwinian biology supports an Aristotelian view of ethics as rooted in human nature. Defending a conception of "Darwinian natural right" based on the claim that the good is the desirable, the author argues that there are at least twenty natural desires that are universal to all human societies because they are based in human biology. The satisfaction of these natural desires constitutes a universal standard for judging social practice as either fulfilling or frustrating human nature, although prudence is required in judging what is best for particular circumstances. The author studies the familial bonding of parents and children and the conjugal bonding of men and women as illustrating social behavior that conforms to Darwinian natural right. He also studies slavery and psychopathy as illustrating social behavior that contradicts Darwinian natural right. He argues as well that the natural moral sense does not require religious belief, although such belief can sometimes reinforce the dictates of nature.

Provides the intellectually curious reader with a solid and fair discussion of the classical philosophical questions about our moral thinking and surveying the main types of meta-ethical and normative ethical theories while not excluding the more recent discussions of moral realism, anti-realism, and virtue morality.

Created from Animals offers a provocative look at how Darwinian evolution undermines many tenets of traditional philosophy and religion. With this sweeping survey of the arguments, the philosophers, and the deep implications surrounding Darwinism, Rachels lays the foundations for a new view of morality. Virbrantly written and provocatively argued, Created from Animals offers a new perspective on issues ranging from suicide to euthanasia to animal rights.

Kai Nielsen is well-known for his work in the field of ethics. Why Be Moral? is a collection of some of Nielsen's most influential and useful essays on the basis or grounding of morality itself from a non-religious point of view.

To the best of my knowledge, this is the best single volume on the realism/anti-realism dispute in contemporary meta-ethics. Basically, what is at issue between realists and anti-realists is the objectivity of ethics. According to Sayre-McCord, the central issue is the existence of moral facts. Realists claim that such facts exist; anti-realists deny their existence. There is more to the debate than this, however. The following is a list of claims that most realists will make about morality: (i) there are moral facts (or moral truths), and these facts (or truths) are mind-independent in some important way; (ii) cognitivism about moral discourse is true: that is, moral moral claims purport to describe moral facts (or moral truths), and (at least some of) these claims successfully do so; and (iii) moral knowledge is possible, and we have some of it. ~ ctdreyer

The argument from conscience is one of the only two arguments for the existence of God alluded to in Scripture, the other being the argument from design (both in Romans). Both arguments are essentially simple natural intuitions. Only when complex, artificial objections are made do these arguments begin to take on a complex appearance. The simple, intuitive point of the argument from conscience is that everyone in the world knows, deep down, that he is absolutely obligated to be and do good, and this absolute obligation could come only from God. Thus everyone knows God, however obscurely, by this moral intuition, which we usually call conscience. Conscience is the voice of God in the soul.
