Defences of inference to the best explanation (IBE) frequently associate IBE with scientific realism, the idea that it is reasonable to believe our best scientific theories. I argue that this linkage is unfortunate. IBE does not warrant belief, since the fact that a theory is the best available explanation does not show it to be (even probably) true. What IBE does warrant is acceptance: taking a proposition as a premise in theoretical and/or practical reasoning. We ought to accept our best (...) scientific theories since they are the theories that are most likely to lead to the goal of science, which is that of knowledge. In support of this claim I invoke Bill Lycan's Panglossian reflections regarding Mother Nature.1. (shrink)

History and the modern sciences are characterized by what is sometimes called a methodological naturalism that disregards talk of divine agency. Some religious thinkers argue that this reflects a dogmatic materialism: a non-negotiable and a priori commitment to a materialist metaphysics. In response to this charge, I make a sharp distinction between procedural requirements and metaphysical commitments. The procedural requirement of history and the sciences—that proposed explanations appeal to publicly-accessible bodies of evidence—is non-negotiable, but has no metaphysical implications. The metaphysical (...) commitment is naturalistic, but is both a posteriori and provisional, arising from the fact that for more than 400 years no proposed theistic explanation has been shown capable of meeting the procedural requirement. I argue that there is nothing to prevent religious thinkers from seeking to overturn this metaphysically naturalistic stance. But in order to do so they would need to show that their proposed theistic explanations are the best available explanations of a range of phenomena. Until this has been done, the metaphysical naturalism of history and the sciences remains defensible. (shrink)

While a great deal of abuse has been directed at intelligent design theory (ID), its starting point is a fact about biological organisms that cries out for explanation, namely "specified complexity" (SC). Advocates of ID deploy three kind of argument from specified complexity to the existence of a designer: an eliminative argument, an inductive argument, and an inference to the best explanation. Only the first of these merits the abuse directed at it; the other two arguments are worthy of respect. (...) If they fail, it is only because we have a better explanation of SC, namely Darwin's theory of evolution by natural selection. (shrink)

A number of recent historians claim to have defeated what they call the ‘conflict thesis’, the idea that there exists some inevitable conflict between Darwinism and Christianity. This is often thought to be part of a broader ‘warfare thesis’, which posits an inevitable conflict between science and religion. But, all they have defeated is one, relatively uninteresting form of this thesis. There remain other forms of the conflict theses that remain entirely plausible, even in light of the historical record.

Theistic evolutionists often suggest that one can reconcile evolutionary theory with biblical teaching. But in fact Christians have accepted Darwinian theory only after reinterpreting the opening chapters of Genesis. Is such a reinterpretation justified? Within Western Christian thought, there exists a hermeneutical tradition that dates back to St Augustine and which offers guidelines regarding apparent conflicts between biblical teaching and natural philosophy (or “science”). These state that the literal meaning of the text may be abandoned only if the natural-philosophical conclusions (...) are established beyond doubt. But no large-scale scientific theory, such as Darwin’s, can claim this degree of certainty. It follows that to justify their reinterpretation of Genesis 1–3, Christians must either argue that the literal sense of the biblical text can be maintained or accept that the Augustinian view of biblical authority is untenable. Three alternative views are discussed: a first that attempts to limit the scope of biblical authority, a second that distinguishes between the Bible and the Word of God, and a third that abandons the idea that religious faith offers certain knowledge. While the third view seems the most defensible, it comes at a cost: the recognition that, as John Locke put it, “reason must be our last judge and guide in everything.”. (shrink)

In his 1615 letter to the Grand Duchess Christina of Lorraine, Galileo argues for a “principle of limitation”: the authority of Scripture should not be invoked in scientific matters. In doing so, he claims to be following the example of St Augustine. But Augustine’s position would be better described as a “principle of differing purpose”: although the Scriptures were not written in order to reveal scientific truths, such matters may still be covered by biblical authority. The Roman Catholic Church has (...) rejected Galileo’s principle, opting rather for Augustine’s, leaving open the possibility of future conflicts between scientists and Church authority. (shrink)

Colin Cheyne has argued that under certain circumstances an internalist or deontological theory of epistemic justification will give rise to a paradox. The paradox, he argues, arises when a principle of epistemic justification is both justifiably believed (in terms of the theory) and false. To avoid this paradox, Cheyne recommends abandoning the principle of justification-transference, which states that acts of believing made on the basis of a justifiably-believed principle are themselves justified. Since such a principle seems essential to any internalist (...) theory of justified believing, internalist theories may also need to be abandoned. I argue that while some theories of epistemic justification may indeed give rise to this paradox, an internalist or deontological theory of subjective justification will avoid it. The reason for this is that a false principle of justified believing does not render acts of believing subjectively unjustified, provided that the agent does not realize that the principle is false.

David Friedrich Strauss is best known for his mythical interpretation of the Gospel narratives. He opposed both the supernaturalists (who regarded the Gospel stories as reliable) and the rationalists (who offered natural explanations of purportedly supernatural events). His mythical interpretation suggests that many of the stories about Jesus were woven out of pre-existing messianic beliefs and expectations. Picking up this suggestion, I argue that the Gospel writers thought paradigmatically rather than historically. A paradigmatic explanation assimilates the event-to-be- explained to what (...) is thought to be a prototypical instance of divine action. It differs from a historical or scientific explanation insofar as it does not specify the conditions under which it should be applied. It is, therefore, a wonderfully flexible way to understand the present in the light of the past. (shrink)
