Right after Philo’s about-face in Part 12 of the Dialogues, he gives an argument that the dispute between the theist and the atheist is merely verbal. Since everything is at least a little like everything else, the atheist must concede that the source of order is at least remotely like a human intellect, even if this source is something like a rotting turnip. This passage provides a major argument for dismissing Hume’s apparent avowals of theism in the Dialogues and elsewhere, (...) since Philo’s assertions are so loose as to let in a rotting turnip. The right reading of the passage is more interesting. The paragraph was written in 1776, right before Hume’s death. It’s thus one of the few philosophical texts written late enough to reflect his encounter with the French philosophes in the 1760s. We have good biographical evidence that Hume was criticized for being too much of a theist in France. The turnip is rotting not in order to make fun of the argument from design, but in order to make fun of d’Holbach's and Diderot's account of the origin of life, accounts that generalized dramatically from John Needham’s observations of nematodes in rotting wheat. In the rotting turnip paragraph, Hume is attempting to establish that the dispute between the theist and the atheist isn’t empirically tractable, that atheists will never outflank the apophatic theologian on the question of whether human minds are unlike God, and that if atheists are consistent with their analogical methods, they ought to be more open to the argument from design.

The first argument that Hume offers against believing in miracle stories in Part 2 of his essay on miracles relies on social context in a way that makes it difficult to follow. Hume says that there’s never been a miracle story that’s well enough attested with respect to certain criteria of testimonial strength. A little later in the essay, he cites recent miracle stories coming from that Saint Médard cemetery as meeting the criteria to an exceptionally high degree, but even (...) so, he claims that we can dismiss the stories out of hand. The hidden background assumption is that his Protestant readers wouldn’t have been tempted to believe in miracle stories coming from an oppressed Catholic sect. Other examples in Part 2 of the essay work in the same way. Hume praises to the skies the quality of the evidence for an earlier Jansenist miracle, for a miracle involving the restoration of a leg through holy water at a Catholic cathedral, and a miracle at a temple of Serapis knowing that his readers won’t be inclined to believe in any of them. The point is that these miracles are better attested than the miracle stories in the Bible, and if we shouldn’t believe in the better attested stories, then we shouldn’t believe in the worse. This can seem like an appeal to prejudice, but really Hume is doing something subtler. He knows that it’s easier to criticize the irrational beliefs of others, but sees that once we turn the same standards that we use on others on our own beliefs, epistemic progress is possible.

In an Enquiry Concerning Human Understanding, Hume distinguishes between two approaches to what we might call psychology: first, one that appeals to common sense to make virtue seem attractive and second one that attempts to describe the principles governing the mind. Within the second approach, he distinguishes two parts: first, a descriptive branch he calls ‘mental geography’ and, second, a branch he compares to Newton’s project in astronomy. I explain the Hume’s vision of Newtonian psychology, and then I explain its (...) application to Hume’s psychological theory in the first Enquiry. Hume’s attempt to explain causal inference in Part 2 of Section 5 is shown to be an attempt at Newtonian psychology: it’s speculative, explanatory, and attempts to enunciate a psychological law. The paper closes by asking whether Hume succeeded in his attempt to put psychology on Newtonian foundations. (shrink)

The common view that Hume is a regularity theorist about laws of nature isn’t textually well grounded. The texts show that he thinks of them as objective governing principles that could conceivably be violated while still counting as a law of nature. This is a standard view at the time, and Hume borrows it from others. He implies that the best evidence for rational religion is the exceptionless workings of the laws of nature, he argues that suicide isn’t incompatible with (...) the will of God by identifying his will with the laws of nature, and he has Philo argue for the existence of God from the simplicity of the laws governing the world. He sheds some of the theological baggage that laws of nature carry at the time, but not all of it. (shrink)

In the “Contrary Miracles Argument,” Hume argues that the occurrence of miracle stories in rival religions should undermine our belief in the trustworthiness of these reports. In order for this argument to have any merit, it has to be understood in its historical, religious context. Miracle stories are used in support of religions, and it's part of religion as we find it to reject miracle stories from rival traditions. A defender of miracle stories could avoid the argument by breaking the (...) connection between miracles and religious doctrine, but then miracles won't justify revealed religion. (shrink)

When we see the way that the parts of the Appendix concerning belief hang together, we can understand how and why Hume moved from saying that belief is a vivid idea to saying that belief is a sui generis feeling. In the Appendix to the Treatise, Hume retracts his claim that perceptions with the same object only vary with respect to vivacity. In material in the appendix that he tells his reader to insert in Book 1, he explains his reasons: (...) the vivacity connected to belief is different in kind from that from the vivacity connected to poetry. Poetry can be more vivid, in its way, than belief. Since Hume’s main arguments for the thesis that beliefs are vivid ideas in the main body of the Treatise depend on the assumption that ideas with the same object only vary in vivacity, he owes us new arguments from his claim. He provides various arguments for a slightly revised thesis that belief is a particular sort of vivid idea at the beginning of the Appendix. (shrink)

Two arguments in Hume’s essay on miracles are reductios ad Catholicism: if you believe in the miracles in the Bible, then you ought to believe in Catholic miracles as well. Hume’s intended readers hated Catholicism and would sooner reject miracles than follow the pope. Hume argues that Jansenist miracle stories meet the standards of trustworthiness as well as any miracles in history. He knows that his Protestant believers don’t believe the stories, and he hopes to persuade his readers to reject (...) any testimony that falls short of that standard. In the ‘Contrary Religions Argument,’ Hume argues that contrary religions should undermine our belief in the trustworthiness of miracle reports. The main contrary religion Hume has in mind is Catholicism, since most miracles stories are Catholic, and Hume’s readers would have rejected them out of hand. He then concludes that if most religiously motivated testimony for miracles is false such testimony is generally unreliable, including testimony for Biblical miracles. (shrink)
