One of the arguments open theists give for the view that God doesn't know the future exhaustively is that several biblical passages seem to indicate God changing his mind. This is indeed how the text is worded in several places. In Genesis 18, God is about to destroy Sodom and Gomorrah, but Abraham pleads with him to spare it even if there are ten righteous people there. As it turns out, there's just one, Abraham's nephew Lot. So God still destroys it, but he spares Lot.
I once thought David Hume's reasons for being skeptical about scientific laws were inconsistent with his arguments against miracles. He argues that we can't know about scientific laws or causes, because all we perceive are one thing happening followed by another thing happening. We don't perceive any causing, just the things we take to be cause and effect. Our taking it to be cause and effect is thoroughly irrational, Hume says, and thus we know nothing about whether there are any causes or scientific laws. For all we know, a ball you throw into the air could come back down, as you expect it, or it could turn into a bird and fly away. We expect it to do the former, but there's no reason we have to think it can't do the latter.
Hume goes on to say that we should never believe in miracles, because you should always proportion your belief to the evidence, and there is zero evidence for miracles. He rules out the very possibility of miracles, it seems, and he does this in the very same work where he has spent so much time setting up worries about whether our entire scientific understanding of the world might be wrong, leaving us with the result that, for all we know, basketballs might turn into seagulls and fly away. How can he consistently say both of these things?
But then I read Hume more closely in subsequent readings, and I came to the conclusion that Hume's approach is consistent after all. What he says in his skepticism about science is that we don't know there are scientific laws of the sort that we believe in if we think one thing makes another happen. He also says that, for all we know, unexpected things that would seem to violate the laws of physics that we believe in could be possible. But he does go on to give a pragmatist account of why we might as well believe in scientific laws anyway, since it's served us well so far, and it's not as if we can help it anyway. It's also not as if we have a choice.
But then in the miracles chapter, he gives a careful argument. He first defines probability as how often something happens in our own personal experience. Then he says that, if you haven't experienced miracles, it follows that miracles have zero probability. But why, then, could he say that plants could sprout legs and start walking around, as far as we know? Isn't that like a miracle? But he's careful here. If we believe that a plant did such a thing, we'd be believing in a miracle. We shouldn't do that, because it has zero probability. It's never happened, in my experience, so I should think it has zero probability. At the same time, I can't rule it out. So it's not impossible, as far as I know. If I did witness it, I'd have to proportion my beliefs with the evidence I then had. But as it is, I shouldn't believe in such things. I should just believe in their possibility, but I shouldn't allow for anything more than zero probability.
The key here is in defining probability in terms of how often it's happened in your experience, while defining possibility in terms of whether it's consistent with your experience. Something could then have zero probability but be well within the realm of possibility. So, because of that, I came to think that Hume's view was indeed consistent, even if it's a strange set of views.
But now I've become convinced again that there's a deep inconsistency in Hume's approach to these two issues. It has to do with his willingness to extend pragmatist arguments toward functioning the way we ordinarily do with respect to the scientific skepticism he begins with, while not extending pragmatism toward functioning the way we ordinarily do with the issue of miracles. He accepts our ordinary views on scientific laws, even though he insists that such beliefs are irrational and not grounded in anything more likely to produce true beliefs than crystal-ball gazing, at least as far as we can be sure. He relies on the testimony of other people in order to believe in regularities in nature that he can rely on to live his life. He refuses to accept the testimony of other people when it comes to miracles, however.
I recently rewatched the 1975 Doctor Who episode "Genesis of the Daleks" by Terry Nation. Some online discussions I looked at about "Genesis of the Daleks" made some interesting, and to my mind obviously false, claims about how it fits (or doesn't) into the overall canonical fictional world of Doctor Who.
One claim in particular claim that caught my interest was the accusation that Terry Nation contradicted some of his earlier Doctor Who episodes about the Daleks in giving the origin of the Daleks in this serial. One discussion pointed out that Nation had made an effort not to contradict his first serial "The Daleks" from 1963, where he establishes the Daleks as creations of a race called the Dals in their war against the Thals. The supposed contradiction comes with "Genesis of the Daleks" when Nation actually shows us this war between the Thals and the race that created the Daleks, and the creator race is not called the Dals but is called The Kaleds.
Here's my problem. This is not a contradiction. A contradiction takes the form 'P and not-P". There is nothing of that form here. What you do have is:
1. The race who created the Daleks at the time of the Daleks' creation called themselves the Kaleds.
2. The Thals also called them the Kaleds at that time.
3. At a much later time, probably many centuries later, after an apocalyptic destruction of all civilization and a loss of a good deal of accurate information about the details of that earlier time, someone speaks of the race that created the Daleks as the Dals.
I'm sorry, but I'm not seeing how any of that makes for an inconsistency. If we were sure the person telling us they were called the Dals was speaking the truth, that would even be difficult to get a contradiction, because it's possible they came to be called the Dals at some time after "Genesis of the Daleks" or that they were called that at some earlier time, and that name came to be the more common one to use again after the apocalypse. But we can't even be sure the Thal telling us this has the right information. Maybe it's just that the wrong name was preserved. There are quite a number of things that could explain how 1-3 might all be true. Terry Nation simply did not contradict his earlier Dalek stories. What he did is use a different name without explaining why different names were used at those two different times, but it's not a contradiction.
I think there's a certain personality type that just likes to find contradictions in everything. A lot of fan criticism of science fiction and fantasy stories exhibits similar problems to the one I've been discussing here. I could point out lots of other examples. That doesn't mean there aren't legitimate criticisms to level against authors. I've criticized J.K. Rowling in print about her concept of changing the past in the third Harry Potter novel, although I did so after pointing out some rather implausible ways of making the story work to avoid the problem I raised. The implausibility there would involve reliable narrators who would know better telling untruths, however, which is more of a stretch than someone centuries after an apocalyptic event getting a name of an extinct civilization wrong or the possibility that the group was actually called by two different names.
How you evaluate such attempts to make canonical worlds coherent in part does depend on how plausible the explanation might be to avoid the contradiction. It's nice for fictional worlds to be coherent. Sometimes that's impossible. Sometimes it involves an implausibility but is possible. And sometimes it's not all that implausible if you just think a little harder to see how things might fit together, when at first they seem not to.
It's hard not to think of critics who like to find contradictions in the Bible when I look at these stories. There are some genuine difficulties in fitting together some parts of the Bible. I've never seen one that guarantees a contradiction, especially when you take into account that inerrantists don't take the current manuscripts to be inerrant but allow for errors in transcription from manuscript to manuscript. But I have seen places where it's not easy to come up with one highly plausible explanation that shows for sure why the apparent contradiction is not a real one. In most of them, there have been several explanations, where not one stands out as the most plausible, and even most of them involve something somewhat unlikely but possible. There's none I know of where I would judge all the explanations as so implausible as to require rational evaluators to think it has to involve two contradictory statements that can't be resolved. But I'm coming from an epistemological standpoint where I think the prior plausibility is relatively high. I consider myself to be in a position where I think I have good reasons for taking the Bible as it presents itself, as God's word, and it follows from that that it's more likely that there is a solution even if I don't know what it is than that there isn't. So I'm going to take the less-plausible-sounding accounts as less certain, but I'm going to be more likely to think that one of them is probably true.
That's one difference with fictional worlds. I don't believe there even are Daleks or Time Lords, never mind that the entire Doctor Who canon is consistent. (I think it certainly isn't coherent when it comes to fundamental questions of time travel, for example.) But someone who thinks God is real and is basically the way God is presented in the Bible is going to place a higher prior probability on there being some resolution to a proposed contradiction than someone who has no prior trust in those documents. And I would argue that someone doing this is right to do so if the prior probability is based on a good epistemic state to begin with. And that makes accepting truth in texts that are hard to fit together much easier to do (and not in a way that undermines rationality, assuming the prior probability itself has a rational grounding.
That assumption of prior probability, of course, is one of the fundamental disputes to begin with, but you can't just assume at the outset that someone who is more willing to trust a set of scriptures is wrong in doing so, and pointing to potential contradictions isn't necessarily going to turn the tide of the conversation unless you first undermine the prior probability. Supposed but not actual contradictions, even if they are difficult to put together, are therefore very weak evidence against the coherence of a worldview when the person who holds that worldview is more sure of it than they are of the irresolvability of the supposed contradiction. That makes for people coming from very different standpoints evaluating the supposed contradictions very differently, and from within their world view each seems to themselves to be right in how they do that. That's something that I think not enough people on either side of such debates can see.
I heard late last night about William P. Alston's death earlier in the day, strangely not through any departmental channels but through a friend who never met him. He was one of the professors I've most respected in my entire academic career. He wrote his dissertation with Wilfred Sellars on the work of Alfred North Whitehead but spent most of his career on philosophy of language, philosophy of religion, and epistemology. Along with Alvin Goldman and Alvin Plantinga, he helped spearhead the externalist/reliabilist revolution in epistemology, a tradition that I think took things in the right direction. He also was one of the most important figures in the revival of philosophy of religion in the last four decades from a point where it had become looked upon as a joke except to reject traditional religious views to a point where some of the most important philosophers today are Christians or other theists. Alston himself was not a Christian when he began his philosophical career, a path shared with several other notable Christian philosophers (Norman Kretzmann and Peter van Inwagen come to mind).
It was always encouraging to me to think about how successful he was in philosophy given his personality and philosophical temperament, which I think are similar to mine in a number of ways that I'm not like most of my philosophical colleagues. He wasn't a system-builder. He wrote about what he had something to say about but wasn't trying to put together a comprehensive philosophical view on every issue he could have something to say about.
Most of his work didn't involve coming up with brilliant views on cutting-edge issues that no one had ever thought of before (although I think there are a few occasions of that in his work, especially in his most recent work in epistemology). He tended to favor traditional views, sometimes so traditional that the majority in philosophy had left the view so far behind that they considered it a joke until people like him came along to disabuse them of such notions by defending the views in novel ways.
Some of the most important philosophical figures are noteworthy for one or both of those reasons (system-building and novel views). Alston, however, filled a role of simply doing good philosophy, often in small but important details. He might see a fallacious argument that was nonetheless popular and apply an important distinction, perhaps one known to the medievals but often ignored by contemporary philosophers, to show why the argument fails. He found elements of competing views that might be compatible and explained why a moderating position might be better than either original view. He applied new arguments in epistemology, philosophy of language, philosophy of mind, or metaphysics to some problem in philosophy of religion to show why a new trend in a completely different area makes Christian belief more favorable (e.g. his application of functionalism, a recent view in materialist philosophy of mind, to explain how language about God can be literally true even if not used in exactly the same sense as the same terms are used for us).
It was clear to me that his long-time colleague and friend Jonathan Bennett had little interest in a lot of the issues in philosophical theology that Alston spent a good deal of time on. In one instance in their Locke/Leibniz class, Bennett dismissed an objection I was raising against his criticism of Leibniz because he didn't want to get into the particular theological issue of God's relation to time, whereas Alston had been nodding along with my objection the whole time. Yet Bennett had tremendous respect for Alston and had been so thoroughly impressed with Alston's argument in Perceiving God that he insisted he publish the bits that weren't about God separately so as to get a wider audience, which resulted in his The Reliability of Sense Perception. Bennett had so much respect for Alston that he insisted on having Alston teach four of the six sessions on Locke in his Locke/Leibniz seminar whenever Alston was available to do it, and he tried for two decades to get Alston to publish his fascinating paper on how Locke's philosophy of language in a relatively obscure section of the Essay requires innate ideas, which he famously rejects earlier in the Essay.
Several directions in his work were influential in my own thinking:
In the first post, I gave some indications of why I think denying God's foreknowledge of free human acts doesn't really explain that much evil. What I'd like to do now is lay out a number of elements of the traditional response to the problem of evil, the one that open theists find unsatisfying. This will all be at a fairly basic level, but I'd like to get all the general things on the table before going into depth on how denying foreknowledge is supposed to help.
One of the primary strategies for responding to the problem of evil is to treat some good as a higher-order good in the sense that it can't exist without allowing some evil to exist yet the good is worth the evil it allows in some sense. Many traditional presentations of the problem of evil have assumed utilitarianism, and thus they will talk about the consequences for happiness and unhappiness, saying that more unhappiness is created than the happiness that requires it, so it's not ultimately worth it. Some theists have responded that utilitarianism is false, and thus the theist has more resources to explain evil. Some kinds of evil may simply be wrong to prevent, with no relevant questions about how much evil is allowed by not doing that wrong thing. If it's wrong to do it, then God shouldn't be expected to do it. So I don't want to assume utilitarianism here, even though it's easier to frame the problem of evil if you do have such assumptions. The way to think of higher-order goods in a non-utilitarian framework would be to see some goods as being so important that it would be wrong not to pursue them. Alternatively, one might simply see preventing certain evils as morally wrong, because any method of preventing that kind of evil would involve doing something wrong. Most theodicies or defenses (I'm not going to deal with the distinction some philosophers make between the two) fall under some kind of higher-order good, I would say.
I've gotten the sense that the problem of evil is the primary motivation for many who subscribe to what's commonly called open theism, i.e. the view that God does not know the future, takes risks, and changes his mind due to learning new information.
Some open theists take God to have voluntarily given up the right to have knowledge of the future for the sake of human freedom. The assumption is that divine foreknowledge and human freedom are incompatible. Other open theists take God's ignorance of the future to be a necessary fact about the nature of time, since there's no future to be known. This view assumes what I call a growing block theory of time. Some think it follows from presentism, i.e. the view that the present exists but the future and past don't, but if presentism is going to justify the view that there are no truths about the future, then it must also justify the view that there are no truths about the past. So it assumes a growing block view, according to which past and present exist but no future, since those truths aren't somehow sense "fixed".
I share neither of these assumptions, so I have little sympathy for open theism, but my concern here isn't to deal with those elements. I'm interested in a different motivation for open theism, the motivation that God's ignorance of the future can explain the kinds and amount of evil in the universe in a much more satisfying way than any other view. I just don't think that's true.
There's a debate within those who believe in some sort of rational defense of Christianity about how it should be done. The main lines of the debate are between what I call the classical apologetics view and the presuppositional view. I've never understood the presuppositionalist position, and all the arguments I've ever seen in favor of it seem so bad to me that I have to think there's something to the view beyond what people seem to me to be saying, but I've still seen no evidence that anyone has a better statement of the view and its claims than the bad ones I've so far seen. I've finally gotten around to putting together my thoughts on why I think presuppositionalism is fundamentally mistaken.
