Philosophers continue to debate about David Hume’s case against the rationality of belief in miracles. This article clarifies semantic, epistemological, and metaphysical questions addressed in the controversy. It also explains the main premises of Hume’s argument and discusses criticisms of them. The article concludes that one’s evaluation of Hume’s argument will depend on one’s views about (a) the definitions of ’miracle’ and ’natural law’; (b) the type of reasoning one ought to employ to determine the probability that a particular miracle (...) claim is true; and (c) whether reasonable people proportion their beliefs about the occurrence of miracles to their evidence.

The conservation of energy and momentum have been viewed as undermining Cartesian mental causation since the 1690s. Modern discussions of the topic tend to use mid-nineteenth century physics, neglecting both locality and Noether’s theorem and its converse. The relevance of General Relativity has rarely been considered. But a few authors have proposed that the non-localizability of gravitational energy and consequent lack of physically meaningful local conservation laws answers the conservation objection to mental causation: conservation already fails in GR, so there (...) is nothing for minds to violate. This paper is motivated by two ideas. First, one might take seriously the fact that GR formally has an infinity of rigid symmetries of the action and hence, by Noether’s first theorem, an infinity of conserved energies-momenta. Second, Sean Carroll has asked how one should modify the Dirac–Maxwell–Einstein equations to describe mental causation. This paper uses the generalized Bianchi identities to show that General Relativity tends to exclude, not facilitate, such Cartesian mental causation. In the simplest case, Cartesian mental influence must be spatio-temporally constant, and hence 0. The difficulty may diminish for more complicated models. Its persuasiveness is also affected by larger world-view considerations. The new general relativistic objection provides some support for realism about gravitational energy-momentum in GR. Such realism also might help to answer an objection to theories of causation involving conserved quantities, because energies-momenta would be conserved even in GR. (shrink)

I reject the Humean approach to the possibility of miracles and offer a tradition-constituted approach which argues for the possibility of miracles. The Humean tradition, I argue, is based on three false assumptions: one, that the laws of nature are prescriptive and hence inevitable; two, that consequently miracles must be conceived as violations of laws of nature and hence impossible; and three, that miracles so conceived must therefore be ascertainable by nontheists and theists alike. In contrast, I argue, one, that (...) laws of nature explain "dispositional properties" of natural processes and allow for novelty and creativity; two, that miracles properly conceived are occurrences whose proximate, sufficient, and necessary cause is God; and three, that miracles are therefore possible and ascertainable only to those whose presuppositions include belief in God.

The claim that a miracle is a violation of a law of nature has sometimes been used as part of an a priori argument against the possibility of miracle, on the grounds that a violation is conceptually impossible. I criticize these accounts but also suggest that alternative accounts, when phrased in terms of laws of nature, fail to provide adequate conceptual space for miracles. It is not clear what a ???violation??? of a law of nature might be, but this is (...) not relevant to the question of miracles. In practice, accounts of miracle tend to be phrased in terms of God's act not in terms of laws of nature. Finally, I suggest that the a priori argument reflects an intellectual commitment that is widely held, though wrongly built into the argument itself. (shrink)
