an autodidact meets a dilettante…

I’m always taken in a thousand different directions by my vagabond mind, as the history of my blog shows, but philosophy has long been an interest, more recently neglected due to trying to keep up, unsuccessfully of course, with the wonders of scientific discovery and speculation. A move away from rational to empirical stuff you might say, if only it was that simple.

So I recently listened to a very wordy debate presented on the Reasonable Doubts podcast between Jeffrey Jay Lowder (atheist) and Kevin Vandergriff (theist) on whether metaphysical naturalism (essentially the scientific approach) or Christian theism yields the best understanding of the universe (or multiverse?), based on ‘the evidence’. It sounded like a good idea at the time, as it sounded like it might be as much a report on empiricism – presenting the evidence – as a philosophical debate. Not surprisingly though, I became increasingly frustrated as I listened, especially to Vandergriff’s long-winded, fast -paced exposition of way too many points (he had to get everything in within the specified time limit, and was still gushing when the end-game theme music started playing). Vandergriff has clearly been inspired by the ‘success’ of William Lane Craig’s debating tactics, even trying to outdo WLC in the number of debating points that he claims must be rebutted by Lowder in order to ‘win’. Well, if wishes were fishes the sea would be swarming.

So the bewildering number of points (though many of them tediously familiar to anyone acquainted with WLC’s arguments) and the speed of delivery naturally reminded me of the old ‘gish gallop’, and my response is to regain control by taking my own good time to pick apart the arguments, so replacing the debate approach with a more effective ‘philosophical’ one, in writing. Not that this was a public debate; it was a written-and-read audio exchange, and many of the comments, linked to above, deal pretty effectively with Vandergriff’s fails. I’m just doing this to get back in the saddle, so to speak.

I won’t be dealing so much with Lowder’s pro-naturalism argument except where it supports my own, but generally I thought that there was too much emphasis, on both sides, on the old philosophical approaches, and not enough on evidence per se.

Vandergriff starts by saying he wants to defend three claims:

1. Christian theism is not significantly less simple than specified naturalism.

(Vandergriff doesn’t explain what he means by ‘specified’ here, and seems to use it as a technical term. A google search on ‘specified naturalism’ has come up with nothing (though the creationist William Dembski likes to use the term ‘specified complexity’), so I will assume he simply means metaphysical naturalism as per the debate title.

2. If God [i.e. the god called God] exists necessarily, then the prior probability of naturalism, no matter how simple, is zero.

3. Christian theism has significantly more explanatory power and scope than specified naturalism.

Before listening to Vandergriff’s defence of these claims I want to make some preliminary remarks. On (1), presumably Vandergriff has the Ockham’s Razor heuristic in mind – keep your assumptions to a minimum. But obviously Christian theism involves two assumptions over and above the assumptions of naturalism (that all is natural and potentially explicable in naturalistic terms). It assumes not only that there’s a supernatural agent responsible for the multiverse, but that the said supernatural agent is the god called God, who had an earthly son who was also a god, sort of, and all the other baggage that attaches to him, or them. These are big assumptions, and, to my mind, far from simple. On (2) yes, if any supernatural agent exists necessarily, I suppose that means supernaturalism reigns supreme and naturalism is vanquished. All we need is evidence, but not only can we not find any, we don’t even know what we’re looking for. Concepts like supreme goodness and maximal power are no more real than Plato’s ideal forms. We don’t call them ideal for nothing. And on (3), it seems to me that the explanatory power of naturalism is virtually infinite, because each new explanation leads to a host of new things to be explained (e.g the DNA molecule is discovered to be the essential building block of all life, but then why is it made up of precisely these amino acids, and why this sequence and why the helical structure, and why introns and exons, etc etc). Christian theism seems to me more like an evasion of explanation, and the ‘don’t question God’s handiwork’ argument was in fact quite prevalent in the 17th century and before, and was often used effectively to limit scientific inquiry.

Vandergriff next defines his god for us, with the usual ‘ideal form’ language. The god called God is maximally powerful, intelligent and good. I’ve elsewhere described this abstraction as a boob: a benevolent, omniscient, omnipotent being. Do boobs really exist? I’d like to hope so, the more the merrier. But I may be confusing my concepts here, so I’ll stick with gods. The god called God, according to Vandergriff, is a transcendent, personal being who created the physical world, and who sent a set of moral messages to us via Jesus.

Vandergriff emphasises his contention that a personal being (a being with personhood, just like us?) caused the physical world (presumably the multiverse) to exist, and that this multiverse is value-generating rather than indifferent, as it is claimed to be under naturalism. He also claims that, under naturalism, the universe or multiverse is eternal and uncaused, which his theism disputes. I would’ve thought naturalism remains open to the questions of ‘eternality’, finitude or infinitude, and ultimate causation. My own recent readings on the universe/multiverse tell me that cosmologists have many positions on these matters, though all approach them from a naturalistic perspective.

Next Vandergriff returns to the 3 claims stated above. He takes issue with Lowder for presupposing an indifferent universe in some of his arguments, which he cites another philosopher, Paul Draper, as claiming ‘is roughly equal in simplicity to theism’. One wonders how these various simplicities can be weighed or measured, by Draper or anyone else. Presumably all that’s meant by this is that it’s just as straightforward to posit a naturalistic universe, with no intrinsic value, as it is to posit a supernatural-being-created universe, full of value. Vandergriff thinks that this goes a long way to prove the claim that theism is not a more complex explanation than naturalism, and this somehow bolsters theism. But it seems to me, on reflection, that the two cases are not roughly equal in simplicity, because with theism, first you have a supernatural creator, second you have value-adding, so to speak. In fact, these two elements struck me as separate when I first leaned about a supernatural creator as a child sent to Sunday School. Full of skepticism and curiosity about this new entity I was learning about, I wondered, how do we know this being is so concerned about us being good? If he created the world in the long ago, why does that automatically mean he’s still obsessed with us? If he’s so all-powerful and super-clever, why wouldn’t he want to test his powers on some new project, just as I might build a fabulous house out of lego and then abandon it for bigger and better projects? In other words, couldn’t a supernatural creator be indifferent too? Or only interested for a period before turning his attention to something else? Vandergriff would get round this objection, I suppose, by pointing to his assumptions about the supernatural being, especially the one about ‘goodness’. An all-good god would never abandon his creation but would, apparently, be eternally obsessed by it. But I’m not sure that perfect goodness (whatever that means) entails this, and anyway these are just assumptions.

Now to Vandergriff’s second claim. Again he quotes Paul Draper, who says that if the god called God necessarily exists, then naturalism is incoherent and theism has a probability of 1. That’s a long-winded way of saying if theism has to be true, it’s true, like absolutely. Of course, that’s a big if, possibly bigger than the known universe. However, at this stage, Vandergriff provides no evidence for this necessary existence (though he says he has two arguments up his sleeve).

On the third contention, Vandergriff goes straight into argument.

1.  God is the best explanation for the origin of the universe.

Here, Vandergriff cites the 2003 Borde Guth Vilenkin theorem relating to an expanding universe (and, I think, other universe models), to support his argument that the universe is non-eternal, to which one commentator on the Reasonable Doubts blog replied tersely ‘Yet another William Lane Craig clone abusing the Borde Guth Velenkin theorem’. In fact I’ve dealt with this claim myself well enough in one of my responses to WLC’s typical debates. Of course the issue here is not whether the universe had a beginning, but what was the cause of that beginning, or what were the conditions at that beginning, or is it meaningful to talk of a ‘before’ the beginning. But here’s where the likes of Vandergriff and WLC make the leap into metaphysics or the supernatural with wild talk of a transcendent, miraculous cause, which, of course, allows tremendous scope for the imagination. The fact is, we’re far from clear about the origin. I’ve read one hypothesis that the big bang may have been the result of a collision or interaction between two ‘branes’, of which there are presumably many in the multiverse. I’ve also read that, as we get asymptotically close to the big bang (going backwards), the laws of nature break down in the super-intensity of it all, so who knows? The Borde Guth Vilenkin theorem, moreover, even on Vandergriff’s (and WLC’s) much-disputed interpretation of it, doesn’t disconfirm naturalism at all, because naturalism is not dependent on an eternal, uncaused universe. Says who?

But it really gets ridiculous when Vandergriff, having proved to his satisfaction that the universe must have a cause, ‘wonders’ what that cause might be, and concludes that it must be an ‘unembodied mind’ (gifted, of course, with miraculous powers). How did he come to this conclusion? Well, this mind must be miraculous because it ‘created the world with no prior materials’. How does Vandergriff know this? The obvious answer is: he doesn’t, he’s just making stuff up. And why would this ‘transcendent’ cause have to be an unembodied mind? Because, according to Vandergriff, only abstract objects and unembodied minds can transcend the universe, but since abstract objects can’t cause anything, the cause must be an unembodied mind!

But of course an unembodied mind is just another abstract object. There are no real unembodied minds that we know of (though Fred Hoyle sort of created one in The Black Cloud, but that one didn’t go around creating universes, in spite of being super-smart), and Vandergriff doesn’t even consider it a requirement to prove that such things exist. As for ‘miraculous’, that just reminds me of the old cartoon – which I’ve put on top of this post.

I’ll have a look at Vandergriff’s next argument, and so forth, in my next post, though I’m not sure why I’m bothering. It’s good mind-exercise I suppose.

For now, though, I’ll watch some FKA Twigs videos, for delightful relief.
