disassembling Kevin Vandergriff’s gish gallop, part 3

Argument 7: God is the best explanation of the connection between the flourishing of the kinds of moral agents there are, and the necessary moral truths that apply to them.

Here we move more and more into the field of the preposterous, IMHO. He quotes a Christian philosopher, Gregory Ganssle, as saying:

Not only do we have beings to which necessary moral truths apply, but we have beings that are made up in such a way that doing what is right turns out to be good for them, it contributes to their flourishing rather than their languishing. Maybe only one in ten universes that are moral, in that they have the right sorts of beings that are such that moral goodness, and the flourishing of those beings involved, converge.

The last sentence is virtually meaningless, but the emphasis here on necessary moral truths is bizarre. I’m not sure what they are, but I’m certain that I haven’t the slightest interest in the concept. Vandergriff spoke earlier of the prohibition against murder as being a necessary moral truth, but many Christians are in favour of capital punishment, which is murder by the state. The murder of Bin Laden a couple of years ago raised very little moral outrage, nor does the murder of hostage-takers and other terrorists today. So these are apparently moral prohibitions that are on some occasions more ‘necessary’ than others.

I find the pretence of surprise that acting on ‘necessary moral truths’ seems coincidentally to promote human flourishing to be ridiculous and thoroughly disingenuous. The fact is that we’ve promoted human flourishing through social evolution. One of the most comprehensive explanations of how this has been achieved is presented by Steven Pinker in The better angels of our nature, a work of empiricism, not philosophy. Pinker has no more interest in ‘necessary moral truths’ than I do, he is concerned to explain how some human populations, and an increasing proportion of them, have been able to learn from the destructive errors of the past and to build better legal, economic, political, social, health and education systems, to better balance co-operation and competition, and individual and social goods. His analysis owes nothing to ‘necessity’, everything to the lessons learned through bitter and often traumatic experience. There are no perfect systems, but polities can be improved grindingly through continued analysis and experiment based on hard-won knowledge. Vandergriff and Ganssle put the cart before the horse. We flourish because the systems we put in place are designed for our flourishing. Yes, horror of horrors, our morality is all about enlightened self-interest, not ‘necessary goodness’. The horrors of the Great War drove us to attempt, for the first time in history, an organisation of international co-operation. Its dissolution was a setback rather than a complete failure. The later United Nations, with all its failings, has gradually grown in strength and will continue to be a force for peace, together with other international and intergovernmental organisations. The success of Medicins sans frontieres has spawned similar organisations ‘without borders’, and the trend is likely to continue. People get enormous satisfaction from helping others. Selfish satisfaction? Yes, but that vastly oversimplifies the matter. It is above all the satisfaction of being connected, which is so important for perhaps the most social species on the planet. And our increasing knowledge of our connections with other species is expanding our circle of sympathy, as philosopher Peter Singer has eloquently pointed out.

But as you might be able to detect, my sympathy with these arguments is starting to run out, and it gets worse.

Argument 8: God is the best explanation of why there are self-aware beings.

It should be pointed out that supernatural beings of any kind (let alone the mass-murdering war-god of the Old Testament) are always massively problematic ‘explanations’ because they have no empirical foundation. These are abstract objects, in spite of their variously imagined ‘histories’ in innumerable sacred texts. The development of self-awareness in many species on our planet is a contingent empirical fact.

Argument 8 and all the other ‘best explanation’ arguments given by Vandergriff, William Lane Craig and other theists are usually  accompanied by claims that ‘this situation/these events are extremely improbable under naturalism but entirely consistent/to be expected under theism’. That’s to say, they’re all ‘cart before the horse’ arguments. You define your supernatural agent as the repository of necessary truths, the generator of all value, the seat of ‘infinite consciousness’ (as Vandergriff quotes J P Moreland, another theist philosopher and theologian, as claiming), and the source of all meaning and ‘worthwhileness’ (argument 10), and then you say ‘hey look, we are value-seeking, meaning-requiring, self-aware, necessary-truth-understanding beings, so surely the whole kit-and caboodle was made by a god who made us as close to him as anything else, because he cares so much for us. Otherwise, all our amazing attributes are meaningless.’ I should point out that the amazing attributes of non-human species are constantly downplayed by theists, as they are in Vandergriff’s spiel, because they don’t contribute anything to this unique god-human relationship. They were downplayed throughout the Christian era too, of course, before it was challenged by the theory of natural selection. Stephen Jay Gould has cited many cases in his essays: for example the early 19th century German embryologist Lorenz Oken wrote that

The animal kingdom is only a dismemberment of the highest animal, that is, of Man

and in an 1835 work, naturalist William Swainson reflected thus:

When we discover evident indications of a definite plan, upon which all these modifications have been regulated by a few simple and universal laws, our wonder is as much excited at the inconceivable wisdom and goodness of the SUPREME by whom these myriads of beings have been created and are now preserved, as at the mental blindness and perverted understanding of those philosophers, falsely so called, who would persuade us, that even Man, the last and best of created things, is too insignificant for the special care of Omnipotence.

We readily forgive these dated claims, partly because they don’t directly challenge us any more, bit it seems clear that many theists have learned nothing and forgotten nothing over the centuries. There are many obvious problems with this way of thinking, but the one I find most indigestible is that in order to avoid the horrors of contingency, which, certainly in the case of William Lane Craig, is the greatest and most unacceptable horror of all, theists are still forced to conclude that everything – the possibly-infinite multiverse, the big bang, quasars, black holes, dark matter and dark energy, gravity, quantum mechanics, the laws of nature, the elements and their proportions etc etc – was created by their god for us. We, containing so many of the god’s qualities, albeit in infinitesimal proportions, are the fulfilment of his purpose. We are what he created it all for. Not a geocentric universe perhaps, but an anthropocentric one for sure, with a complexity that the god gradually reveals to us as our privilege to work out.

So theism here presents us with a choice, or so it believes: total meaninglessness, or the humbling knowledge that we are central to a god’s plan, the pinnacle of his creation, created in his image, fumbling caretakers of his multiverse. As fantasies go, it’s a whopper. From an empiricist perspective however, it’s a non-starter, except in psychological terms. It has helped our forebears to get through many dark nights of history.

I’ll dispense quickly with Vandergriff’s last two arguments. Argument 10, God is the best explanation for the worthwhileness of life, is just more of the same and requires no further analysis. Argument 9, probably the most preposterous of all the arguments, is that ‘God is the best explanation of the historical facts about Jesus of Nazareth’. There are no historically established facts about Jesus of Nazareth, even of his birth, his preaching, his trial and his death, let alone of his putative miracles and resurrection. Scholars may argue to and fro about these matters, but their arguments are entirely textual and have no serious empirical value.

Okay, I’m done with this. Never again, I hope.

Feeling almost apologetic for dwelling on this for too long, with so many more important themes to tackle. Of course some out there, especially in those most heatedly devout parts of the USA, might consider that no more essential topic exists than giving proper due to the supernatural creator of the universe, but I would disagree, and I suppose here’s where I get to say why.

I was discussing Vandergriff’s third contention, that ‘Christian theism has significantly more explanatory power and scope than specified naturalism’. Here is his second argument for this:

God is the best explanation for why space-time and all its contents exist, rather than nothing.

Of course space-time has only existed as a familiar concept for about a century. It may well be replaced, or amended, by another concept, and I’m sure Christian theists will find their god to be the best explanation for that too. He’s amazingly flexible that way. Vandergriff here talks of a proof of supernatural causation under the presupposition that the universe is eternal but necessarily caused. It’s rather an unsurprising one drawn from a famous conundrum of quantum mechanics, that quantum indeterminacy can only be resolved through observation. The observation ‘collapses the wave function’. Vandergriff, or the person who posits this ‘proof’, then leaps from quantum states to the state of the universe. ‘What, or who, collapses its wave function?’ Vandergriff asks. This doesn’t strike me as a particularly valid leap. It seems more a desperate grab for an analogy. I’m not that boned up on my fallacies, but this might be the fallacy of the excluded middle, inter alia. I mean, ‘quantum/universal indeterminacy, therefore god’ does seem to take for granted an awful lot of in-between stuff. The supposed essential recourse to the disembodied mind again suggested here fails as Vandergriff has not presented any argument to show that this ‘disembodied mind’ is anything more than an abstract object. The play of such words as ‘necessary’ and ‘contingent’ really get us nowhere in providing answers to the very interesting questions around the beginnings of our universe and the well-established weirdness of quantum mechanics, regardless of whether the two are related.

The third argument is taken directly from William Lane Craig:

God is the best explanation of the applicability of mathematics to the physical world.

I’ve answered this claim from Craig here, though I’m amused at Vandergriff’s gloss, in that we’re still not sure that the Higgs boson has been discovered, as the data could well fit other scenarios. In any case, the main point about mathematics is clear. Mathematics seems highly abstract nowadays because over time and through painstaking human effort it has moved a long way from its beginnings. Mathematics developed as a tool to describe particular objects in general terms, that could be manipulated and developed, for example number, leading to multiplication, division, functions and the various forms of calculus. All of these, and further, developments make use of regularities, or explore regularities (some of which have as yet no known applicability). It’s hard to conceive of a physical world that has no regularity. All elements are describable, mathematically, in terms of their properties, which are regular, i.e. describable. Try to describe something that has no regularity at all. It would have no shape, no boundary between it and not-it. If this convinces you that a creator god exists, it’s likely that you were already convinced. As to a super-rational creator, which Vandergriff tries to point to, that would hardly be the brutal monster of the Old Testament who slaughters children and babies in a flood and supports the massacres of whole populations in favour of his ‘chosen people’.

Argument 4: God is the best explanation of the discoverability of the universe.

This is really just a repetition of the previous argument. The universe, to be physical (and therefore discoverable in terms of its properties) has to be regular. However, human development ‘at just the right time’ to discover the universe’s properties and origins  supposedly supports a fine-tuning argument, as developed by Hugh Ross, a Christian astrophysicist who put forward this argument in the early nineties. The late Victor Stenger, among many others, has put these arguments to the sword. There’s also a problem with this and with other ‘best explanation’ arguments in that they are essentially self-refuting ‘first cause’ arguments. David Hume was one of the first to point out the deficiencies of such arguments centuries ago. Attempts to improve on them are well summarised and dealt with by the philosopher Theodore Schick here. To me, one of the best-arguments against fine-tuning relating we humans to the supernatural creator is its grotesquely overwhelming wastefulness. Why create a universe so enormously inhospitable to intelligent life throughout almost the entirety of its vast expanse in order to permit we humans to finally thrive on our small planet through a history of great suffering? A super-rational being could surely do better, and chance seems a much more coherent explanation.

Argument 5: God is the best explanation of why there are embodied morally responsible agents.

I presume Vandergriff is talking here about cetaceans. Or maybe not. In any case, the existence of such agents, he claims, is more probable under theism. Presumably his claim is based here on the idea that it would be more fun to create a universe with moral agents in it than, say, living beings who are little more than scuttling stomachs. Yet considering how enormously complex and diverse these scuttling stomachs are, it seems clear that, if Vandergriff’s god created them, he seems to have found them great fun. You can hardly argue with J B S Haldane’s remark that the guy has an inordinate fondness for beetles.

Vandergriff talks about the unique human ability for self-control and control over our environment because ‘our brains are the most complex things in the universe’. How does he know this? Well, he doesn’t. This line has often been used, by Richard Dawkins amongst many other scientists, but always, as far as I’m aware, with the cautionary addendum ‘according to our current knowledge’. And our current knowledge of the universe, I and many others would argue, is minuscule, in spite of the great strides we’ve made. Vandergriff is concerned here to emphasise human specialness. He describes, without providing any names, how various physical scientists have been ‘stunned’ to discover that the universe must have been fine-tuned to extraordinary precision to provide for this embodied moral agency. Yet this moral agency appears to exist, to varying degrees, in a number of social species on our planet (which Vandergriff doesn’t acknowledge). In any case, I’m sure plenty of other prominent physical scientists could be found who are considerably less ‘stunned’.

Argument 6: God is the best explanation of moral agents who apprehend necessary moral truths.

I don’t believe there are ‘necessary moral truths’, and I don’t find this a particularly interesting philosophical theme, though it obviously strongly exercises some philosophers.

In giving his example taken from Darwin and the behaviour of hive bees, however, Vandergriff completely misrepresents natural selection, comparing what natural selection ‘happens upon’ with the rational choices of human beings. I would strongly argue that there is more to natural selection than just ‘happening upon’ or ‘chance’ as theists like to describe it. Most theists like to think we’re rational moral agents guided by, or able to be guided by, their god; though how the god does the guiding can never be properly answered. Vandergriff cites the prohibition against rape as a necessary moral truth, but Christians have raped women throughout history, in times of warfare, just as readily as have members of other religions. Rape statistics are notoriously difficult to compare from nation to nation, because states have different laws, definitions, reporting methods and resources. It’s clear from even the most casual examination that cultural attitudes to rape vary widely. We don’t find a consistent or clear-cut prohibition against rape in the Bible. However in modern western countries, especially with the advent of feminism, rape has been raised to a higher level of seriousness as a crime. This hasn’t been driven by organised religion, so it just seems absurd to assert, or even to intimate, that the prohibition against rape is a necessary truth derived from a supernatural being.

Vandergriff talks about natural selection or evolution as being only conducive to our survival, and seems to find it unlikely that our ‘necessary moral truths’ or our aesthetic tastes or even such traits as benevolence or kindness could have been selected for, claiming that these qualities are unlikely under naturalism but highly likely under theism. Yet it’s abundantly clear that reducing the incidence of rape, developing better medicines, resolving conflicts by peaceful means, promoting sympathy for others, including those of other species, and exercising restraint and thoughtfulness in our personal lives is conducive, not only to our survival, but to our success and our enrichment. We’ve learned this, not through communication with spirits, but through honest examination of our own past behaviour as a species. It seems to me that it’s through these painstaking examinations that we’re learning to reduce our common misery and to promote our well-being. We’re learning from our mistakes, even if it’s a ‘two steps forward, one step back’ process. A thorough-going education system is essential in disseminating what we’ve learned from the past and carrying those gleanings into the future. It’s precisely because there are no necessary truths, because we could always go back to achieving our ends through brutality, dishonesty and blinkered self-promotion, that we need to maintain awareness of past errors, and of the complex needs of those around us and to whom we’re attached, including humans and non-humans.

Vandergriff has more ‘arguments’, which I’ll deal with next time, though I’m looking for ways to cut this short!
