This is a response to Cavin and Colombetti’s paper criticizing a claim of mine elsewhere, that God would not permit anyone to deceive the world by manufacturing evidence which made it probable that Jesus was God incarnate when that was not so. I analyze four different cases of A allowing B to hold a false belief, and I argue that only two of them constitute deception by A, one being “straightforward” deception and the other “tacit” deception. What I should have claimed earlier is that God would not deceive us on this matter, including doing so by permitting someone else to manufacture deceptive evidence.

God has major reasons for intervening in human history by becoming incarnate himself—to identify with our suffering, to provide atonement for our sins, and to reveal truths. Given there is at least a significant probability that there is a God, there is at least a modest probability that he would become incarnate and live a life and provide teaching appropriate to one who sought thereby to realize these goals. Jesus lived and taught in the appropriate way. If it was God incarnate who did so live and teach, he would need to show us that it was God who had done so, and so could be expected to put his signature on that life and teaching by a super-miracle, such as the Resurrection. So there is a modest prior probability in advance of considering the direct historical evidence of the Resurrection, to expect that it would happen to someone who lived and taught as Jesus did. Jesus is the only person in human history about whom there is significant evidence both that he led the appropriate kind of life, and that his life was culminated by a super-miracle. So we do not need too many witnesses to the empty tomb or too many witnesses who claimed to have talked to the risen Jesus, to make it probable that Jesus did indeed rise. We do have some such witness evidence, which it is very improbable would occur unless the Resurrection occurred. In consequence it is overall very probable that the Resurrection occurred.

Cavin and Colombetti correctly affirm that in judging the probability of a hypothesis we should take into account “the total available evidence.” However, they neglect their own affirmation when they claim that I make an unwarranted assumption that God would not massively deceive the human race, when they claim that I do not take into account any evidence favoring hypotheses incompatible with the traditional account of what happened to the body of Jesus, and when they claim that I do not take into account the evidence that humans have a strong propensity to private sinning.

Keith Ward understands the Trinity as “one conscious being” and the divine “persons” as three necessary modes of divine action. But he does not give a good reason for supposing that there must be just three modes of divine action. I argue that by contrast all the theories of the Trinity developed from the Nicene Creed by patristic and medieval writers, are “social” theories, or “three persons” theories. I defend my a priori argument for the justification of a social theory—that three persons are the necessary minimum for the realization of perfect love, and the necessary maximum for this.

Suppose we transplant the left hemisphere of one person, Alexandra, into the skull of another person, Alex, from whom both cerebral hemispheres have been removed; and transplant Alexandra’s right hemisphere into the skull of another person, Sandra, both of whose cerebral hemispheres have been removed. Both of the resulting persons will then have some of Alexandra’s brain and probably almost all of her memories and character. But since at most only one of them can be Alexandra, being Alexandra must, by the “principle of the identity of composites,” involve having another essential non-physical part—her soul. It is our soul and only our soul which makes us who we are.

Mr Olding's recent attack on my exposition of the argument from design gives me an opportunity to defend the central theses of my original article. My article pointed out that there were arguments from design of two types—those which take as their premisses regularities of copresence and those which take as their premisses regularities of succession. I sought to defend an argument of the second type. One merit of such an argument is that there is no doubt about the truth of its premisses. Almost all objects in the world behave in a highly regular way describable by scientific laws. Further, any scientific explanation of such a regularity must invoke some more general regularity. The most general regularities of all are, as such, scientifically inexplicable. The question arises whether there is a possible explanation of another kind which can be provided for them, and whether their occurrence gives any or much support to that explanation. I urged that we do explain some phenomena by explanation of an entirely different kind from the scientific. We explain states of affairs by the action of agents who bring them about intentionally of their own choice. Regularities of succession, as well as other phenomena may be explained in this way. Explanation of this kind I will term intentional explanation. Intentional explanation of some phenomenon E consists in adducing an agent A who brought E about of his own choice and a further end G which, he believed, would be forwarded by the production of E.
