The argument from design stands as one of the most intuitively compelling arguments for the existence of a divine Creator. Yet, for many scientists and philosophers, Hume's critique and Darwin's theory of natural selection have definitely undermined the idea that we can draw any analogy from design in artifacts to design in nature. Here, we examine empirical studies from developmental and experimental psychology to investigate the cognitive basis of the design argument. From this it becomes clear that humans spontaneously discern purpose in nature. When constructed theologically and philosophically correctly, the design argument is not presented as conclusive evidence for God's existence but rather as an abductive, probabilistic argument. We examine the cognitive basis of probabilistic judgments in relationship to natural theology. Placing emphasis on how people assess improbable events, we clarify the intuitive appeal of Paley's watch analogy. We conclude that the reason why some scientists find the design argument compelling and others do not lies not in any intrinsic differences in assessing design in nature but rather in the prior probability they place on complexity being produced by chance events or by a Creator. This difference provides atheists and theists with a rational basis for disagreement.

The simplest Divine Command Theory is one which identifies rightness with being commanded or willed by God. Two clear and appealing arguments for this theory turn on the idea that laws require a lawgiver, and the idea that God is sovereign or omnipotent. Critical examination of these arguments reveals some fundamental principles at odds with the Divine Command Theory, and yields some more penetrating versions of traditional objections to that theory.

Philosophers expend considerable effort on the analysis of concepts, but the value of such work is not widely appreciated. This paper principally analyses some arguments, beliefs, and presuppositions about the nature of design and the relations between design and science common in the literature to illustrate this point, and to contribute to the foundations of design theory.

Recent proponents of a divine command ethics have chiefly defended the theory by refuting objections rather than by offering “positive reasons” to support it. We here offer a catalogue of such positive arguments drawn from historical discussions of the theory. We presentarguments which focus on various properties of the divine nature and on the unique status of God, as well as arguments which are analogical in character. Finally, we describe a particularform of the theory to which these arguments point, and indicate how they counteract a standard criticism of it. Throughout we pick up on previous work of Philip Quinn.

Richard Dawkins has a dilemma when it comes to design arguments. On the one hand, he maintains that it was Darwin who killed off design and so implies that his rejection of design depends upon the findings of modern science. On the other hand, he follows Hume when he claims that appealing to a designer does not explain anything and so implies that rejection of design need not be based on the findings of modern science. These contrasting approaches lead to the following dilemma: if he claims that Darwinism is necessary for rejecting design, he has no satisfactory response to design arguments based on the order in the laws of physics or the fine-tuning of the physical constants; alternatively, if Humean arguments are doing most of the work, this would undermine one of his main contentions, that atheism is justified by science and especially by evolution. In any case, his Humean arguments do not provide a more secure basis for his atheism because they are seriously flawed. A particular problem is that his argument for the improbability of theism rests on a highly questionable application of probability theory since, even if it were sound, it would only establish that the prior probability of God’s existence is low, a conclusion which is compatible with the posterior probability of God’s existence being high.

The “existential inertia” thesis holds that, once in existence, the natural world tends to remain in existence without need of a divine conserving cause. Critics of the doctrine of divine conservation often allege that its defenders have not provided arguments in favor of it and against the rival doctrine of existential inertia. But in fact, when properly understood, the traditional theistic arguments summed up in Aquinas’s Five Ways can themselves be seen to be (or at least to imply) arguments against existential inertia and in favor of divine conservation. Moreover, they are challenging arguments, to which defenders of the existential inertia thesis have yet seriously to respond.

This book explores recently opened avenues in logic and philosophical analysis to offer new perspectives on time-honored religious beliefs. Topics covered include the nature of divine attributes, the implications of divine benevolence and divine justice, arguments in support of theism and atheism, and religion and morality.

In this article, after reviewing traditional arguments from design, I consider some more recent versions: the so-called ‘new design arguments’ for the existence of God. These arguments enjoy an apparent advantage over the traditional arguments from design by avoiding some of Hume’s famous criticisms. However, in seeking to render religion and science compatible, it seems that they require a modification not only of our scientific understanding but also of the traditional conception of God. Moreover, there is a key problem with arguments from design that Mill raised to which the new arguments seem no less vulnerable than the older versions. The view that science and religion are complementary has at least one significant advantage over other positions, such as the view that they are in an antagonistic relationship or the view that they are so incommensurable that they are neither complementary nor antagonistic. The advantage is that it aspires to provide a unified worldview that is sensitive to the claims of both science and religion. And surely, such a worldview, if available, would seem to be superior to one in which, say, scientific and religious claims were held despite their obvious contradictions. Given this, it should come as no surprise that many religious thinkers have been attracted to the view that science and religion are complementary. Here, I wish to consider a cluster of arguments exemplifying this position: namely, ‘new design arguments’ for the existence of God. These arguments rely directly on developments in late twentieth-century natural science in attempting to establish their conclusions. One question that will need to be addressed is: To what extent are they susceptible to the criticism that they only succeed by distorting the religious beliefs they claim to champion? But before we examine new design arguments, it would be wise to consider first of 1 all the traditional arguments from design, and note some of the problems they have faced..

There seems to be a widespread conviction — evidenced, for example, in the work of Mackie, Dawkins and Sober — that it is Darwinian rather than Humean considerations which deal the fatal logical blow to arguments for intelligent design. I argue that this conviction cannot be well-founded. If there are current logically decisive objections to design arguments, they must be Humean — for Darwinian considerations count not at all against design arguments based upon apparent cosmological fine-tuning. I argue, further, that there are good Humean reasons for atheists and agnostics to resist the suggestion that apparent design — apparent biological design and/or apparent cosmological fine-tuning — establishes (or even strongly supports) the hypothesis of intelligent design.
