Most people who comment on the cosmological argument demonstrably do not know what they are talking about.  This includes all the prominent New Atheist writers.  It very definitely includes most of the people who hang out in Jerry Coyne’s comboxes.  It also includes most scientists.  And it even includes many theologians and philosophers, or at least those who have not devoted much study to the issue.  This may sound arrogant, but it is not.  You might think I am saying “I, Edward Feser, have special knowledge about this subject that has somehow eluded everyone else.”  But that is NOT what I am saying.  The point has nothing to do with me.  What I am saying is pretty much common knowledge among professional philosophers of religion (including atheist philosophers of religion), who – naturally, given the subject matter of their particular philosophical sub-discipline – are the people who know more about the cosmological argument than anyone else does. 

In particular, I think that the vast majority of philosophers who have studied the argument in any depth – and again, that includes atheists as well as theists, though it does not include most philosophers outside the sub-discipline of philosophy of religion – would agree with the points I am about to make, or with most of them anyway.  Of course, I do not mean that they would all agree with me that the argument is at the end of the day a convincing argument.  I just mean that they would agree that most non-specialists who comment on it do not understand it, and that the reasons why people reject it are usually superficial and based on caricatures of the argument.  Nor do I say that every single self-described philosopher of religion would agree with the points I am about to make.  Like every other academic field, philosophy of religion has its share of hacks and mediocrities.  But I am saying that the vast majority of philosophers of religion would agree, and again, that this includes the atheists among them as well as the theists.

I’m not going to present and defend any version of the cosmological argument here.  I’ve done that at length in my books Aquinas and The Last Superstition, and it needs to be done at length rather than in the context of a blog post.  The reason is that, while the basic structure of the main versions of the argument is fairly simple, the background metaphysics necessary to a proper understanding of the key terms and inferences is not.  It needs some spelling out, which is why Aquinas and The Last Superstition each devote a long chapter to general metaphysics before addressing the question of God’s existence.  The serious objections to the argument can in my view all be answered, but that too can properly be done only after the background ideas have been set out.  And that too is a task carried out in the books.

I will deal here with some of the non-serious objections, though.  In particular, what follows is intended to clear away some of the intellectual rubbish that prevents many people from giving the argument a fair hearing.  To get to the point(s), then:

1. The argument does NOT rest on the premise that “Everything has a cause.”

Lots of people – probably most people who have an opinion on the matter – think that the cosmological argument goes like this: Everything has a cause; so the universe has a cause; so God exists.  They then have no trouble at all poking holes in it.  If everything has a cause, then what caused God?  Why assume in the first place that everything has to have a cause?  Why assume the cause is God?  Etc.

Here’s the funny thing, though.  People who attack this argument never tell you where they got it from.  They never quote anyone defending it.  There’s a reason for that.  The reason is that none of the best-known proponents of the cosmological argument in the history of philosophy and theology ever gave this stupid argument.  Not Plato, not Aristotle, not al-Ghazali, not Maimonides, not Aquinas, not Duns Scotus, not Leibniz, not Samuel Clarke, not Reginald Garrigou-Lagrange, not Mortimer Adler, not William Lane Craig, not Richard Swinburne.  And not anyone else either, as far as I know.  (Your Pastor Bob doesn’t count.  I mean no one among prominent philosophers.)  And yet it is constantly presented, not only by popular writers but even by some professional philosophers, as if it were “the” “basic” version of the cosmological argument, and as if every other version were essentially just a variation on it.

Don’t take my word for it.  The atheist Robin Le Poidevin, in his book Arguing for Atheism (which my critic Jason Rosenhouse thinks is pretty hot stuff) begins his critique of the cosmological argument by attacking a variation of the silly argument given above – though he admits that “no-one has defended a cosmological argument of precisely this form”!  So what’s the point of attacking it?  Why not start instead with what some prominent defender of the cosmological argument has actually said?

Suppose some creationist began his attack on Darwinism by assuring his readers that “the basic” claim of the Darwinian account of human origins is that at some point in the distant past a monkey gave birth to a human baby.  Suppose he provided no source for this claim – which, of course, he couldn’t have, because no Darwinian has ever said such a thing – and suppose also that he admitted that no one has ever said it.  But suppose further that he claimed that “more sophisticated versions” of Darwinism were really just “modifications” of this claim.  Intellectually speaking, this would be utterly contemptible and sleazy.  It would give readers the false impression that anything Darwinians have to say about human origins, however superficially sophisticated, is really just a desperate exercise in patching up a manifestly absurd position.  Precisely for that reason, though, such a procedure would, rhetorically speaking, be very effective indeed.

Compare that to Le Poidevin’s procedure.  Though by his own admission no one has ever actually defended the feeble argument in question, Le Poidevin still calls it “the basic” version of the cosmological argument and characterizes the “more sophisticated versions” he considers later on as “modifications” of it.  Daniel Dennett does something similar in his book Breaking the Spell.  He assures us that the lame argument in question is “the simplest form” of the cosmological argument and falsely insinuates that other versions – that is to say, the ones that philosophers have actually defended, and which Dennett does not bother to discuss – are merely desperate attempts to repair the obvious problems with the “Everything has a cause” “version.”  As with our imaginary creationist, this procedure is intellectually dishonest and sleazy, but it is rhetorically very effective.  It gives the unwary reader the false impression that “the basic” claim made by Aristotle, Aquinas, Leibniz, et al. is manifestly absurd, that everything else they have to say is merely an attempt to patch up this absurd position, and (therefore) that such writers need not be bothered with further.

And that, I submit, is the reason why the stupid “Everything has a cause” argument – a complete fabrication, an urban legend, something no philosopher has ever defended – perpetually haunts the debate over the cosmological argument.  It gives atheists an easy target, and a way rhetorically to make even their most sophisticated opponents seem silly and not worth bothering with.  It‘s a slimy debating trick, nothing more – a shameless exercise in what I have elsewhere called “meta-sophistry.”  (I make no judgment about whether Le Poidevin’s or Dennett’s sleaziness was deliberate.  But that they should know better is beyond question.)

What defenders of the cosmological argument do say is that what comes into existence has a cause, or that what is contingent has a cause.  These claims are as different from “Everything has a cause” as “Whatever has color is extended” is different from “Everything is extended.”  Defenders of the cosmological argument also provide arguments for these claims about causation.  You may disagree with the claims – though if you think they are falsified by modern physics, you are sorely mistaken – but you cannot justly accuse the defender of the cosmological argument either of saying something manifestly silly or of contradicting himself when he goes on to say that God is uncaused.

This gives us what I regard as “the basic” test for determining whether an atheist is informed and intellectually honest.  If he thinks that the cosmological argument rests on the claim that “everything has a cause,” then he is simply ignorant of the basic facts.  If he persists in asserting that it rests on this claim after being informed otherwise, then he is intellectually dishonest.  And if he is an academic philosopher like Le Poidevin or Dennett who is professionally obligated to know these things and to eschew cheap debating tricks, then… well, you do the math.

2. “What caused God?” is not a serious objection to the argument.

Part of the reason this is not a serious objection is that it usually rests on the assumption that the cosmological argument is committed to the premise that “Everything has a cause,” and as I’ve just said, this is simply not the case.  But there is another and perhaps deeper reason.

The cosmological argument in its historically most influential versions is not concerned to show that there is a cause of things which just happens not to have a cause.  It is not interested in “brute facts” – if it were, then yes, positing the world as the ultimate brute fact might arguably be as defensible as taking God to be.  On the contrary, the cosmological argument – again, at least as its most prominent defenders (Aristotle, Aquinas, Leibniz, et al.) present it – is concerned with trying to show that not everything can be a “brute fact.”  What it seeks to show is that if there is to be an ultimate explanation of things, then there must be a cause of everything else which not only happens to exist, but which could not even in principle have failed to exist.  And that is why it is said to be uncaused – not because it is an arbitrary exception to a general rule, not because it merely happens to be uncaused, but rather because it is not the sort of thing that can even in principle be said to have had a cause, precisely because it could not even in principle have failed to exist in the first place.  And the argument doesn’t merely assume or stipulate that the first cause is like this; on the contrary, the whole point of the argument is to try to show that there must be something like this.

Different versions of the cosmological argument approach this task in different ways.  Aristotelian versions argue that change – the actualization of the potentials inherent in things – cannot in principle occur unless there is a cause that is “pure actuality,” and thus can actualize other things without itself having to be actualized.  Neo-Platonic versions argue that composite things cannot in principle exist unless there is a cause of things that is absolutely unified or non-composite.  Thomists not only defend the Aristotelian versions, but also argue that whatever has an essence or nature distinct from its existence – so that it must derive existence from something outside it – must ultimately be caused by something whose essence just is existence, and which qua existence or being itself need not derive its existence from another.  Leibnizian versions argue that whatever does not have the sufficient reason for its existence in itself must ultimately derive its existence from something which does have within itself a sufficient reason for its existence, and which is in that sense necessary rather than contingent.  And so forth.  (Note that I am not defending or even stating the arguments here, but merely giving single sentence summaries of the general approach several versions of the arguments take.)

So, to ask “What caused God?” really amounts to asking “What caused the thing that cannot in principle have had a cause?”, or “What actualized the potentials in that thing which is pure actuality and thus never had any potentials of any sort needing to be actualized in the first place?”, or “What imparted a sufficient reason for existence to that thing which has its sufficient reason for existence within itself and did not derive it from something else?”  And none of these questions makes any sense.  Of course, the atheist might say that he isn’t convinced that the cosmological argument succeeds in showing that there really is something that could not in principle have had a cause, or that is purely actual, or that has a sufficient reason for its existence within itself.  He might even try to argue that there is some sort of hidden incoherence in these notions.  But merely to ask “What caused God?” – as if the defender of the cosmological argument had overlooked the most obvious of objections – simply misses the whole point.  A serious critic has to grapple with the details of the arguments.  He cannot short-circuit them with a single smart-ass question.  (If some anonymous doofus in a combox can think up such an objection, then you can be certain that Aristotle, Aquinas, Leibniz, et al. already thought of it too.)

3. “Why assume that the universe had a beginning?” is not a serious objection to the argument.

The reason this is not a serious objection is that no version of the cosmological argument assumes this at all.  Of course, the kalām cosmological argument does claim that the universe had a beginning, but it doesn’t merely assume it.  Rather, the whole point of that version of the cosmological argument is to establish through detailed argument that the universe must have had a beginning.  You can try to rebut those arguments, but to pretend that one can dismiss the argument merely by raising the possibility of an infinite series of universes (say) is to miss the whole point.

The main reason this is a bad objection, though, is that most versions of the cosmological argument do not even claim that the universe had a beginning.  Aristotelian, Neo-Platonic, Thomistic, and Leibnizian cosmological arguments are all concerned to show that there must be an uncaused cause even if the universe has always existed.  Of course, Aquinas did believe that the world had a beginning, but (as all Aquinas scholars know) that is not a claim that plays any role in his versions of the cosmological argument.  When he argues there that there must be a First Cause, he doesn’t mean “first” in the order of events extending backwards into the past.  What he means is that there must be a most fundamental cause of things which keeps them in existence at every moment, whether or not the series of moments extends backwards into the past without a beginning.

In fact, Aquinas rather famously rejected what is now known as the kalām argument.  He did not think that the claim that the universe had a beginning could be established through philosophical arguments.  He thought it could be known only via divine revelation, and thus was not suitable for use in trying to establish God’s existence.  (Here, by the way, is another basic test of competence to speak on this subject.  Any critic of the Five Ways who claims that Aquinas was trying to show that the universe had a beginning and that God caused that beginning – as Richard Dawkins does in his comments on the Third Way in The God Delusion – infallibly demonstrates thereby that he simply doesn’t know what he is talking about.)

4. “No one has given any reason to think that the First Cause is all-powerful, all-knowing, all-good, etc.” is not a serious objection to the argument.

People who make this claim – like, again, Dawkins in The God Delusion – show thereby that they haven’t actually read the writers they are criticizing.  They are typically relying on what other uninformed people have said about the argument, or at most relying on excerpts ripped from context and stuck into some anthology (as Aquinas’s Five Ways so often are).  Aquinas in fact devotes hundreds of pages across various works to showing that a First Cause of things would have to be all-powerful, all-knowing, all-good, and so on and so forth.  Other Scholastic writers and modern writers like Leibniz and Samuel Clarke also devote detailed argumentation to establishing that the First Cause would have to have the various divine attributes.

Of course, an atheist might try to rebut these various arguments.  But to pretend that they don’t exist – that is to say, to pretend, as so many do, that defenders of the cosmological argument typically make an undefended leap from “There is a First Cause” to “There is a cause of the world that is all-powerful, all-knowing, etc.” – is, once again, simply to show that one doesn’t know what one is talking about.

5. “The argument doesn’t prove that Christianity is true” is not a serious objection to the argument.

No one claims that the cosmological argument by itself suffices to show that Christianity is true, that Jesus of Nazareth was God Incarnate, etc.  That’s not what it is intended to do.  It is intended to establish only what Christians, Jews, Muslims, philosophical theists, and other monotheists hold in common, viz. the view that there is a divine cause of the universe.  Establishing the truth of specifically Christian claims about this divine cause requires separate arguments, and no one has ever pretended otherwise.

It would also obviously be rather silly for an atheist to pretend that unless the argument gets you all the way to proving the truth of Christianity, specifically, then there is no point in considering it.  For if the argument works, that would suffice all by itself to refute atheism.  It would show that the real debate is not between atheism and theism, but between the various brands of theism.  

6. “Science has shown such-and-such” is not a serious objection to (most versions of) the argument.

There are versions of the cosmological argument that appeal to scientific considerations – most notably, the version of the kalām argument defended by William Lane Craig.  But even Craig’s argument also appeals to separate, purely philosophical considerations that do not stand or fall with the current state of things in cosmology or physics.  And most versions of the cosmological argument do not in any way depend on particular scientific claims.  Rather, they start with extremely general considerations that any possible scientific theorizing must itself take for granted – for example, that there is any empirical world at all, or any world of any sort at all.  

It is sometimes claimed (for example, by Anthony Kenny and J. L. Mackie) that some of Aquinas’s arguments for God’s existence depend on outdated theses in Aristotelian physics.  But Thomists have had little difficulty in showing that this is false.  In fact the arguments depend only on claims of Aristotelian metaphysics which can be disentangled from any outdated scientific assumptions and shown to be defensible whatever the scientific details turn out to be, precisely because (so the Thomist argues) they concern what any possible scientific theory has to presuppose.  (Naturally, I address this issue in Aquinas.)

Of course, many atheists are committed to scientism, and maintain that there are no rational forms of inquiry other than science.  But unless they provide an argument for this claim, they are merely begging the question against the defender of the cosmological argument, whose position is precisely that there are rational arguments that are distinct from, and indeed more fundamental than, empirical scientific arguments.  Moreover, defending scientism is no easy task – in fact the view is simply incoherent, or so I would argue (as I have in several previous posts).  Be that as it may, merely shouting “Science!” doesn’t prove anything.  

7. The argument is not a “God of the gaps” argument.

Since the point of the argument is precisely to explain (part of) what science itself must take for granted, it is not the sort of thing that could even in principle be overturned by scientific findings.  For the same reason, it is not an attempt to plug some current “gap” in scientific knowledge.  Nor is it, in its historically most influential versions anyway, a kind of “hypothesis” put forward as the “best explanation” of the “evidence.”  It is rather an attempt at strict metaphysical demonstration.  To be sure, like empirical science it begins with empirical claims, but they are empirical claims that are so extremely general that (as I have said) science itself cannot deny them without denying its own evidential and metaphysical presuppositions.  And it proceeds from these premises, not by probabilistic theorizing, but via strict deductive reasoning.  In this respect, to suggest (as Richard Dawkins does) that the cosmological argument fails to consider more “parsimonious” explanations than an uncaused cause is like saying that the Pythagorean theorem is merely a “theorem of the gaps” and that more “parsimonious” explanations of the “geometrical evidence” might be forthcoming.  It simply misunderstands the nature of the reasoning involved.

Of course, an atheist might reject the very possibility of such metaphysical demonstration.  He might claim that there cannot be a kind of argument which, like mathematics, leads to necessary truths and yet which, like science, starts from empirical premises.  But if so, he has to provide a separate argument for this assertion.  Merely to insist that there cannot be such an argument simply begs the question against the cosmological argument.

None of this entails that the cosmological argument is not open to potential criticism.  The point is that the kind of criticism one might try to raise against it is simply not the kind that one might raise in the context of empirical science.  It requires instead knowledge of metaphysics and philosophy more generally.  But that naturally brings us to the next point:

8. Hume and Kant did not have the last word on the argument.  Neither has anyone else.

It is often claimed that Hume, or maybe Kant, essentially had the last word on the subject of the cosmological argument and that nothing significant has been or could be said in its defense since their time.  I think that no philosopher who has made a special study of the argument would agree with this judgment, and again, that includes atheistic philosophers who ultimately reject the argument.  For example, I don’t think anyone who has studied the issue would deny that Elizabeth Anscombe presented a serious objection to Hume’s claim that something could conceivably come into existence without a cause.  Nor is Anscombe by any means the only philosopher to have criticized Hume on this issue.  I’m not claiming that everyone would agree that the objections leveled by Anscombe and others are at the end of the day correct (though I think they are), only that they would agree that it is wrong to pretend that Hume somehow ended all serious debate on the issue.  (Naturally, I discuss this issue in Aquinas.)

To take another example, Hume’s objection that the cosmological argument commits a fallacy of composition is, as I have noted in an earlier post, also greatly overrated.  For one thing, it assumes that the cosmological argument is concerned with explaining why the universe as a whole exists, and that is simply not true of all versions of the argument.  Thomists often emphasize that the argument of Aquinas’s On Being and Essence requires only the premise that something or other exists – a stone, a tree, a book, your left shoe, whatever.  The claim is that none of these things could exist even for an instant unless maintained in being by God.  You don’t need to start the argument with any fancy premise about the universe as a whole; all you need is a premise to the effect that a stone exists, or a shoe, or what have you.  (Again, see Aquinas for the full story.)  Even versions of the argument that do begin with a premise about the universe as a whole are (in my view and that of many others) not really damaged by Hume’s objection, for reasons I explain in the post just linked to.  In any event, I think that anyone who has studied the cosmological argument in any depth would agree that it is certainly seriously debatable whether Hume draws any blood here.  

In general, critics of the cosmological argument tend arbitrarily to hold it to a standard to which they do not hold other arguments.  In other areas of philosophy, even the most problematic views are treated as worthy of continuing debate.  The fact that there are all sorts of serious objections to materialist theories of the mind, or consequentialist views in ethics, or Rawlsian liberal views in political philosophy, does not lead anyone to suggest that these views shouldn’t be taken seriously.  But the fact that someone somewhere raised such-and-such an objection to the cosmological argument is routinely treated as if this sufficed to establish that the argument has been decisively “refuted” and needn’t be paid any further attention.

Jason Rosenhouse plays this game in his response to my recent post on Jerry Coyne.  Writes Rosenhouse:

Feser seems rather taken with [the cosmological argument], but there are many strong refutations to be found in the literature.  Off the top of my head, I found Mackie's discussion in The Miracle of Theism and Robin Le Poidevin's discussion in Arguing for Atheism to be both cogent and accessible.  

Does Rosenhouse really think that we defenders of the cosmological argument aren’t familiar with Mackie and Le Poidevin?  Presumably not.  But then, what’s his point?  That is to say, what point is he trying to make that doesn’t manifestly beg the question?  After all, what would Rosenhouse think of the following “objection”:

Rosenhouse seems rather taken with the materialist view of the mind, but there are many strong refutations to be found in the literature.  Off the top of my head, I found Foster’s The Immaterial Self and the essays in Koons’ and Bealer’s The Waning of Materialism to be both cogent and accessible.

Or, while we’re on the subject of what prominent mainstream atheist philosophers have said, what would he think of:

Rosenhouse seems rather taken with Darwinism, but there are many strong refutations to be found in the literature.  Off the top of my head, I found Fodor’s and Piatelli-Palmarini’s discussion in What Darwin Got Wrong and David Stove’s discussion in Darwinian Fairytales to be both cogent and accessible.

Rosenhouse’s answer to both “objections” would, I imagine, be: “Since when did Foster, Koons, Bealer, Fodor, Piatelli-Palmarini, and Stove get the last word on these subjects?”  And that would be a good answer.  But no less good is the following answer to Rosenhouse: Since when did Mackie and Le Poidevin have the last word on the cosmological argument?  

“But that’s different!” I imagine Rosenhouse would say.  But how is it different?  This brings us to one last point:

9. What “most philosophers” think about the argument is irrelevant.

Presumably, the difference is in Rosenhouse’s view summed up in another remark he makes in his post, viz. “There's a reason most philosophers are atheists” (he cites this survey as evidence).  By contrast, most philosophers are not dualists or critics of Darwinism (though in fact the number of prominent dualists is not negligible, but let that pass).  Now if what Rosenhouse means to imply is that philosophers who have made a special study of the cosmological argument now tend to agree that it is no longer worthy of serious consideration, then for reasons already stated, he is quite wrong about that.  But what he probably means to imply is rather that since most contemporary academic philosophers in general are atheists, we should conclude that the cosmological argument isn’t worth serious consideration.

But what does this little statistic really mean?  I’ll let Mr. Natural tell us what it means.  Because Rosenhouse’s little crack really amounts to little more than a fallacious appeal to authority-cum-majority.  What “most philosophers” think could be relevant to the subject at hand only if we could be confident that academic philosophers in general, and not just philosophers of religion, were both competent to speak on the cosmological argument and reasonably objective about it.  And in fact there is good reason to think that neither condition holds.

Consider first that, as I have documented in several previous posts (here, here, and here) prominent philosophers who are not specialists in the philosophy of religion often say things about the cosmological argument that are demonstrably incompetent.  Consider further that those who do specialize in areas of philosophy concerned with arguments like the cosmological argument do not tend to be atheists, as I noted here.  If expertise counts for anything – and New Atheist “Learn the science!” types are always insisting that it does – then surely we cannot dismiss the obvious implication that those who actually bother to study arguments like the cosmological argument in depth are more likely to regard them as serious arguments, and even as convincing arguments.

Now the New Atheist will maintain that the direction of causality goes the other way.  It isn’t that studying the cosmological argument in detail tends to lead one to take religious belief seriously, they will say.  It’s rather that people who already take religious belief seriously tend to be more likely to study the cosmological argument.  Of course, it would be nice to hear a non-question-begging reason for thinking that this is all that is going on.  And there is reason for doubting that this can be all that is going on.  After all, there are lots of other arguments and ideas supportive of religion that academic philosophers of religion do not devote much attention to – young earth creationism, spiritualism, and the like.  Evidently, the reason they devote more attention to the cosmological argument is that they sincerely believe, on the basis of their knowledge of it, that the argument is worthy of serious study in a way these other ideas are not, and not merely because they are predisposed to accept its conclusion.

The objection in question is also one that cuts both ways.  For why suppose that the atheist philosophers are more objective than the theist ones?  In particular, why should we be so confident that most philosophers (outside philosophy of religion) are atheists because they’ve seriously studied arguments like the cosmological argument and found them wanting?  Why not conclude instead that, precisely because they tend for other reasons to be atheists, they haven’t bothered to study arguments like the cosmological argument very seriously?  The cringe-making remarks some of them make about the argument certainly provides support for this suspicion.  (Again, I give examples here, here, and here.)

And there is other reason for suspicion.  After all, as philosophers with no theological ax to grind sometimes complain – see here and here for a few examples – their colleagues can too often be smugly insular and ill-informed about sub-disciplines outside their own and about the history of their own field.  And like other academics, they can be unreflective, dogmatic, and uninformed in their secularism.  Here too you don’t have to take my word for it.  Many prominent secular philosophers themselves have noted the same thing.  

Hence Thomas Nagel opines that a “fear of religion” seems often to underlie the work of his fellow secularist intellectuals, and that it has had “large and often pernicious consequences for modern intellectual life.”  He continues:

I speak from experience, being strongly subject to this fear myself: I want atheism to be true and am made uneasy by the fact that some of the most intelligent and well-informed people I know are religious believers.  It isn't just that I don't believe in God and, naturally, hope that I'm right in my belief.  It's that I hope there is no God!  I don't want there to be a God; I don't want the universe to be like that.  My guess is that this cosmic authority problem is not a rare condition and that it is responsible for much of the scientism and reductionism of our time.  One of the tendencies it supports is the ludicrous overuse of evolutionary biology to explain everything about human life, including everything about the human mind… This is a somewhat ridiculous situation… [I]t is just as irrational to be influenced in one’s beliefs by the hope that God does not exist as by the hope that God does exist. (The Last Word, pp. 130-131)

Jeremy Waldron tells us that:

Secular theorists often assume they know what a religious argument is like: they present it as a crude prescription from God, backed up with threat of hellfire, derived from general or particular revelation, and they contrast it with the elegant complexity of a philosophical argument by Rawls (say) or Dworkin.  With this image in mind, they think it obvious that religious argument should be excluded from public life... But those who have bothered to make themselves familiar with existing religious-based arguments in modern political theory know that this is mostly a travesty... (God, Locke, and Equality, p. 20)

Tyler Burge opines that “materialism is not established, or even clearly supported, by science” and that its hold over his peers is analogous to that of a “political or religious ideology” (“Mind-Body Causation and Explanatory Practice,” in John Heil and Alfred Mele, eds., Mental Causation, p. 117)

John Searle tells us that “materialism is the religion of our time,” that “like more traditional religions, it is accepted without question and… provides the framework within which other questions can be posed, addressed, and answered,” and that “materialists are convinced, with a quasi-religious faith, that their view must be right” (Mind: A Brief Introduction, p. 48)

William Lycan admits, in what he himself calls “an uncharacteristic exercise in intellectual honesty,” that the arguments for materialism are no better than the arguments against it, that his “own faith in materialism is based on science-worship,” and that “we also always hold our opponents to higher standards of argumentation than we obey ourselves.” (“Giving Dualism its Due,” a paper presented at the 2007 Australasian Association of Philosophy conference at the University of New England)

The atheist philosopher of religion Quentin Smith maintains that “the great majority of naturalist philosophers have an unjustified belief that naturalism is true and an unjustified belief that theism (or supernaturalism) is false.”  For their naturalism typically rests on nothing more than an ill-informed “hand waving dismissal of theism” which ignores “the erudite brilliance of theistic philosophizing today.”  Smith continues:

If each naturalist who does not specialize in the philosophy of religion (i.e., over ninety-nine percent of naturalists) were locked in a room with theists who do specialize in the philosophy of religion, and if the ensuing debates were refereed by a naturalist who had a specialization in the philosophy of religion, the naturalist referee could at most hope the outcome would be that “no definite conclusion can be drawn regarding the rationality of faith,” although I expect the most probable outcome is that the naturalist, wanting to be a fair and objective referee, would have to conclude that the theists definitely had the upper hand in every single argument or debate.

Due to the typical attitude of the contemporary naturalist… the vast majority of naturalist philosophers have come to hold (since the late 1960s) an unjustified belief in naturalism. Their justifications have been defeated by arguments developed by theistic philosophers, and now naturalist philosophers, for the most part, live in darkness about the justification for naturalism. They may have a true belief in naturalism, but they have no knowledge that naturalism is true since they do not have an undefeated justification for their belief.  If naturalism is true, then their belief in naturalism is accidentally true.  [“The Metaphilosophy of Naturalism,” Philo: A Journal of Philosophy (Fall-Winter 2001)]

Again, Nagel, Waldron, Burge, Searle, Lycan, and Smith are not apologists for religion.  Apart from Smith, they aren’t even philosophers of religion.  All of them are prominent, and all of them are “mainstream.”  They have no motive for saying the things they do other than that that is the way things honestly strike them based on their knowledge of the field.

But scientists shouldn’t get smug over lapses in objectivity among philosophers.  For at least where philosophical matters are concerned, many scientists are hardly more competent or objective, as we have seen in an earlier post, and as the embarrassing philosophical efforts of Richard Dawkins and Stephen Hawking illustrate.  And if you think even their “purely scientific” pronouncements are always free of anything but good old tough-minded “just the facts, ma’am” objectivity… well, as Dawkins will tell you, you shouldn’t believe fairy tales.  Biologist Richard Lewontin let the cat out of the bag some time ago:

Our willingness to accept scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural.  We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism.  It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world but, on the contrary, that we are forced by our a priori adherence to material causes to create an apparatus of investigation and a set of concepts that produce material explanations, no matter how counterintuitive, no matter how mystifying to the uninitiated.  Moreover, that materialism is absolute, for we cannot allow a Divine Foot in the door.  [From a review of Carl Sagan's The Demon-Haunted World in the New York Review of Books (January 9, 1997)]

But here’s the bottom line.  The “What do respectable people say?” stuff that Rosenhouse, Coyne, and other New Atheists are always engaging in is juvenile, and futile too, since they are never able to tell us what counts as “respectable” in a way that doesn’t beg all the questions at issue.  It is amazing how much time and energy New Atheist types put into trying to come up with ever more elaborate excuses for not engaging their critics’ actual arguments.  If that alone doesn’t make you suspicious, then I submit that you are not thinking critically.

Let’s give Jerry Coyne credit.  He asked for advice on what to read in order to understand what theists take to be the rational foundations of their position, I gave him some advice, and now he says he’ll take it.  And so, Jerry Coyne will soon meet Thomas Aquinas.  True, on the subject of the cosmological argument, Coyne still misses the point, which is that the pat “counterarguments” hacks like Dawkins give are superficial and directed at straw men.  Nor did I say he “must read many books” to see at least that much: Just reading a book like my Aquinas would suffice.  The point of my other references was merely to indicate where he might look if he wants to pursue the subject more thoroughly than just relying on little old me.

Do I expect Coyne to become a theist after studying Aquinas, or even to admit that the cosmological argument is more formidable than New Atheist types give it credit for?  Not for a moment – any more than Coyne expects that “Intelligent Design” theorists (my longtime sparring partners) would concede an inch even after reading one of the “one stop” books Coyne cites as sufficient to establish Darwinism.   

But, again, Coyne deserves credit for at least going through the motions, which is more than Dawkins, Myers, et al. bother to do.  In New Atheist Land, that’s a kind of progress.  (And by the way, Prof. Coyne, I’m not the “Skeptic” in the little dialogue presented in my previous post.  I’m the “Scientist.”)

Thứ Hai, 11 tháng 7, 2011

A reader alerts me that Jerry Coyne, whose philosophical efforts we had occasion recently to evaluate, has been reading some theology – “under the tutelage of the estimable Eric MacDonald,” Coyne tells us.  And who is Eric MacDonald?  A neutral party to the debate between theologians and New Atheist types like Coyne, right?  Well, not exactly.  Turns out MacDonald is “an ex-Anglican priest” who has been “wean[ed]… from his faith,” and who claims that “religious beliefs and doctrines not only have no rational basis, but are, in fact, a danger to rational, evidence-based thinking.”

Give Coyne’s post a read, then come back.  Now, you might recall my fanciful dialogue from a few months back between a scientist and a bigoted science-bashing skeptic.  The point was to try, through analogy, to help New Atheist types see how they appear to others, and how irrational and ill-informed they really are.  (If you haven’t seen the dialogue, go read that too, then come back.)  To see what is wrong with Coyne’s latest remarks, we can imagine that that dialogue might continue as follows:

Skeptic: I’m trying to learn science so I can meet head-on the argument that we science critics are ignorant of the subject.  So, under the tutelage of the estimable Bruno Latour, I have spent several weeks reading this stuff.  And so far, I’ve learned only three things.  First of all, I’m wasting my time reading drivel about beliefs that have no basis in fact when I could be learning about real things instead.  Second, scientists can’t write.  A lot of what they have to say is obscure bafflegab, and I’m starting to believe that this obscurantism is deliberate because of reason three (which I’ll get to in a minute).  I have for example, just opened Geons, Black Holes, and Quantum Foam by John Wheeler to a random chapter.  And there I find this: 

“On the other hand, when we see time symmetry marred in an elementary process, when we contemplate the writhings of spacetime in wormholes and quantum foam, when we see tiny deviations from Dirac’s predictions for the electron produced by quantum fluctuations, we realize that the “floor” of simplicity as we move to smaller and smaller domains is illusory.  Beneath that floor, in still smaller domains, chaos and complexity reign again.”

Believe me, the book contains paragraphs far more obscure and pretentious than this one.  Can you imagine reading this stuff night after night?  Do you see why my head feels about to explode?  Bruno, why are you doing this to me?

Scientist: Well, it’s easy to make fun of serious ideas by ripping them out of context.  Actually understanding them is a different story.  Wheeler is an important thinker, and you quite obviously haven’t the faintest understanding of what he’s saying.

Skeptic: Oh brother, here we go again.  “You don’t know what you’re talking about!”  You always say that.  Then comes the Courtier’s reply: “Learn the science before commenting on it!”  But now that I have learned it, even that’s not enough for you.  Why don’t you just finally admit that science is like believing in the Flying Spaghetti Monster?  I mean, “geons” and “quantum foam” are only the beginning.  This Wheeler guy goes on about tons of other crackpot stuff, like “black holes,” “muons,” “cosmic rays,””wave-particle duality,” and “It from Bit,” whatever the hell that means.  

Scientist: But my point is that you haven’t “learned the science.”  Just reading a book doesn’t mean anything if you’re not even trying to understand it.  And you’ve more or less admitted that you’re not – you’re only interested in scoring a debating point against those who’ve exposed your lack of knowledge of science.  There’s nothing obscure or crackpot about anything Wheeler said.  He’s just using technical terminology.  But the ideas are complicated and are the result of decades or even centuries of scientific developments.  You can’t seriously expect to understand it all just by mining a couple of books over the weekend for passages you can make smart-ass remarks about.

Skeptic: But why waste time trying to understand it when these scientists never show how what they’re saying tells us anything about reality in the first place?  Because that’s the third thing I’ve learned.  There seems to be no “knowledge” behind science.  One gets the strong sense when reading science that everyone is just making stuff up.  There are few arguments for relativity, quantum mechanics, evolution, etc. at all in what I read.  People just assume these things are real and go from there.

Scientist: What are you talking about?  Lots of scientists have argued for those things, at length!

Skeptic: Not in what I’ve read these last few weeks.  For example, read a book like Gregory’s Eye and Brain and you’ll find he talks about how evolution did this or how photons do that.  But he never gives us any argument for the existence of these “photon” thingies, and he never answers all the objections people have made to evolution.  It’s all based on faith.

Scientist: He doesn’t address those things at length because the book is about vision, and not photons or evolution per se.  He can take that stuff for granted because other people have argued for it elsewhere.  He isn’t even trying to answer skeptics about evolution or modern physics in a book like that.  Really, do you expect every science book to start from square one and recapitulate what others have already said about every issue that might be relevant to a subject, just to satisfy skeptics like you?  

Skeptic: But their belief in these things is not based on argument.  It’s based on peer pressure, groupthink, the fear of being ostracized.  The so-called “arguments” you refer to are just rationalizations for what scientists were indoctrinated into believing while in school and what all their colleagues expect them to believe when they go to conferences, try to get tenure or funding or to get their papers accepted for publication, etc.  It reflects the worship of science that dominates our society – its pop culture, its educational institutions, commerce and industry, you name it.  It’s all socially constructed, not based in reality.  As Latour says in Laboratory Life…

Scientist: That’s another thing.  When the hell did Bruno Latour, of all people, become a neutral source in this debate?!

Skeptic: What do you mean?  Latour is himself a scientist!  In fact, he’s a recognized expert in no less than two sciences, anthropology and sociology.  He also wrote a very influential study of Einstein’s theory of relativity.  

Scientist: This is surreal.  I don’t think you’ll find a lot of physicists or biologists who would agree that what Latour does is “science.”  I’ll bet even many anthropologists wouldn’t.  And as to his article on relativity…

Skeptic: Ah, I see, so the scientists don’t even agree among themselves about what “science” is.  It’s just a bunch of warring, faith-based sects that…

Scientist: No, there is certainly consensus among serious scientists about…

Skeptic: Oh, so when you cite some scientist, he’s a “serious” scientist or a “real” scientist, but when I cite some scientist in my favor, suddenly he’s not a “real” scientist or a “serious” one.  How convenient!  Do you have any idea how you sound?

Scientist: It only “sounds” suspicious if you’re hell-bent on finding something suspicious about it instead of trying to understand the reasons why I say what I do.  Look, you’re so off-base about so many things that I’ve got to start from first principles even to make a dent, and it’s complicated further by…

Skeptic: Yeah, yeah, it’s “complicated,” I don’t understand the issues, Courtier’s reply, blah blah blah.  Whatever.  You tell me I need to learn about science before criticizing it, so – just to humor you, because I already know it’s a waste of time – I do.  Then, because you don’t like what the evidence I’ve uncovered shows, you suddenly shift your ground and say that reading science books isn’t good enough after all, and that the scientists I cite are not “real” scientists.  I don’t think there’s any point in continuing this conversation any further.  And I don’t think there’s any point in reading any more science.  I don’t want to waste months of my life reading this stuff if there’s nothing to be gained from it except the ability to say to my opponents, “Yes, I do know about scientific schools of thought X, Y, and Z.”  Why bother to torture our brains if we can simply ask scientists to prove, using evidence and reason, that their viewpoint is correct, and better than that of either science critics like me, or other scientists?  But they never do that – it’s all just making stuff up or at best rationalizing preconceived ideas.

Now, Coyne would be outraged by our Skeptic, and rightly so.  But replace “Skeptic” with “Coyne,” “Scientist” with “Theologian,” and so forth, and I submit that you’ve got a dead-on summary of Coyne’s attitude toward theology.  Of course, Coyne and his ilk will insist that the cases are different.  But what you will never get from them is an actual argument for this claim, or at least not an argument that doesn’t beg the question.

If there were any doubt that Coyne’s reading project is unserious, it is dispelled by his jaw-dropping remark that he hasn’t come across any arguments for God’s existence “that aren’t taken up and refuted in The God Delusion.”  If Coyne were to imagine his own reaction to a creationist who said he hadn’t seen any arguments for evolution “that aren’t taken up and refuted in Duane Gish’s Evolution: The Fossils Say No!,” he would have some idea of what a fool he is making of himself.  Reasonable and well-informed people can disagree about whether a thinker like Aquinas (say) has proved the existence of God.  Reasonable and well-informed people cannot disagree about whether Richard Dawkins knows what the hell he is talking about when he criticizes thinkers like Aquinas in The God Delusion.  He does not, and to every Aquinas scholar it is cringe-makingly obvious that he does not.  If Coyne does not know this – and his own clueless past remarks about Aquinas show that he doesn’t – then it is hard to believe that he has even tried to look for serious defenses of the arguments for God’s existence, and thus hard to see how he has any business complaining that he hasn’t found them.

Still, Coyne insists that he really wants to know what the best arguments are, that he is “dead serious here, and not looking for sarcastic answers,” and even that he is “hoping that some real theologians will read this and provide some answers.”  Well, here is an answer.  If Coyne really wants to know what the rational foundations of theology are, he should read works that aim to lay down those foundations, instead of works that presuppose them – just like someone skeptical about evolution should read a book like Coyne’s Why Evolution is True instead of complaining that books like Richard Gregory’s Eye and Brain do not argue for evolution.

Traditionally, the central argument for God’s existence is the cosmological argument, and (also traditionally) the most important versions of that argument are the ones summed up in the first three of Aquinas’s Five Ways.  But the typical modern reader is simply not going to understand the Five Ways just by reading the usual two-page excerpt one finds in anthologies.  For one thing, the arguments were never intended to be stand-alone, one-stop proofs that would convince even the most hardened skeptic.  They are only meant to be brief sketches of arguments the more detailed versions of which the intended readers of Aquinas’s day would have found elsewhere.  For another thing, the terminology and argumentative moves presuppose a number of metaphysical theses that Aquinas also develops and defends elsewhere.

So, to understand the Five Ways, the modern reader needs to read something that makes all this background clear, that explains how modern Thomists would reply to the stock objections to the arguments, and so forth.  Naturally, I would recommend my own book Aquinas, since it was intended in part precisely as an up-to-date explanation and defense of these arguments, and will provide the reader with a useful survey of what not only Aquinas, but the Thomistic tradition more generally, has said about them.  (I do some of this in The Last Superstition too, of course.  But that book does not deal with the Third Way, as the Aquinas book does.  Moreover, New Atheists – who have a sense of humor about everything but themselves – are likely to make the polemical tone of TLS an excuse for dismissing its arguments.  This is unreasonable, of course, especially given their own excessive polemics – I’m only fighting fire with fire – but there it is.)

Another relatively recent book to look at on the Five Ways is Christopher F. J. Martin’s Thomas Aquinas: God and Explanations.  Unfortunately, this is an expensive book, but it looks like the University of Chicago library has a copy, so Coyne should have no trouble getting hold of it.  If Coyne wants to dig even deeper into a broadly Thomistic approach informed by hard core analytic philosophy, I would recommend that he look at Barry Miller’s trilogy: From Existence to God, A Most Unlikely God, and The Fullness of Being.  These are also expensive, but I see that Coyne is again in luck, since the University of Chicago library has all three.  There are also some articles on Aquinas’s arguments worth checking out, such as David Oderberg’s recent piece on the first premise of the First Way.  And then there is the question of how Aquinas would deal with the atheistic objection from evil, the best recent book on which is Brian Davies’ The Reality of God and the Problem of Evil.

After Aquinas’s versions of the cosmological argument, the next most important argument for God’s existence is the kalām cosmological argument.  Here the things to read are William Lane Craig’s books The Kalām Cosmological Argument and Atheism, Theism, and Big Bang Cosmology (co-written with atheist Quentin Smith), and David Oderberg’s articles on the subject (available here, here, here, here, and here).

So, there’s your answer, Prof. Coyne.  No need to thank me!

Continuing our look at alleged cases of the quantifier shift fallacy committed by prominent philosophers, let’s turn to an example from John Locke.  As we’ve seen, Harry Gensler accuses Locke of reasoning as follows: “Everything is caused by something, so there must be some (one) thing that caused everything.”  What does Locke actually say?  The relevant passage is from Book IV, Chapter 10 of the Essay Concerning Human Understanding:

[Man] knows also that nothing cannot produce a being; therefore something must have existed from eternity.  In the next place, man knows, by an intuitive certainty, that bare nothing can no more produce any real being, than it can be equal to two right angles.  If a man knows not that nonentity, or the absence of all being, cannot be equal to two right angles, it is impossible he should know any demonstration in Euclid.  If, therefore, we know there is some real being, and that nonentity cannot produce any real being, it is an evident demonstration, that from eternity there has been something; since what was not from eternity had a beginning; and what had a beginning must be produced by something else.

Notice first that, like other defenders of the cosmological argument, Locke does not actually say “Everything is caused by something” – the atheist’s favorite straw man, which would, of course, invite the atheist’s favorite retort “So what caused God?”  What Locke actually says is that “Nothing cannot produce a being,” that “Nonentity cannot produce any real being,” and so forth.  This entails only that if something has come into being, then it must have had a cause.  It does not entail that everything has a cause.  But this premise isn’t the focus of Gensler’s criticism, and he may not have been trying to paraphrase Locke accurately since this particular misreading does not affect the point he is trying to make. 

But notice also that Locke does not say anything as blatantly fallacious as the argument Gensler attributes to him.  That is, he doesn’t say “Everything that comes into being has a cause, so there must be some (one) thing that caused everything that comes into being.”  To be sure, it is not at all difficult to see why Gensler and others would attribute this fallacy to Locke.  If the fact that “nonentity cannot produce any real being” is somehow supposed to show that “from eternity there has been something,” and if (as is evident from the rest of chapter 10) “something” is supposed to refer to some one particular thing, then it is not unreasonable at least to wonder whether the fallacious argument in question is how Locke gets from his premise to his conclusion.  Still, it would be unreasonable to assume that Locke must have been reasoning that way, if there is some plausible alternative way of reading him.  So is there?

There is.  As commentators on Locke know, his argument for God’s existence was influenced by a more detailed argument developed by the Cambridge Platonist Ralph Cudworth.  You can find a useful discussion of Locke’s argument and of Cudworth’s influence on it in Volume II, Chapter 14 of Michael Ayers’ magisterial Locke: Epistemology and Ontology.  Ayers begins his discussion of Cudworth’s version thus:

The relevant part of Cudworth’s long argument is briefly as follows.  First, since nothing can come from nothing, and something exists, then something must exist from eternity which is causa sui, existing necessarily or essentially (the standard ‘cosmological’ proof).  So far, Cudworth thought, theists and atheistic materialists are undivided.  But the atheists identify the eternal being with matter, arguing that the Lucretian principle that nothing can come from nothing rules out the creation of matter by something else... (p. 171)

As Ayers goes on to note, Cudworth then argues that the problem with taking matter to be the ultimate reality is that matter cannot produce thought, so that the ultimate cause of the thought that exists in the universe must be immaterial.  (As I have noted before, Cudworth was an early and important proponent of the argument that the modern mechanical conception of matter itself, to which the materialist no less than modern dualists like Cudworth is committed, rules out the possibility that mind can be material.)

Now Locke’s argument for God’s existence proceeds in a similar manner, and in general it is evident that Locke intended to reason along lines related to Cudworth’s.  (As Ayers notes, Locke does alter Cudworth’s argument somewhat so as to bring it into line with his own metaphysical commitments, but these alterations are irrelevant to our present concerns.)  But then it is clear how Locke can be interpreted in a way that does not attribute to him any quantifier shift fallacy.  Like Cudworth, what he is saying is that even the atheist (or at least the typical atheist of the day) acknowledges that something must have existed from eternity, even if the atheist takes this “something” to be the substrate of matter that underlies the particular material things that come into being and pass out of being.  The question is whether even matter considered as an eternal being could be the ultimate cause of things.  

In other words, Cudworth and Locke both seem to be arguing along lines similar to those which, as we have seen, Aquinas develops in the first part of the Third Way, in which he shows that something must have always existed, even if only what J. L. Mackie calls the “permanent stock of matter” that persists through the processes of generation and corruption.  As I noted in my book Locke (at pp. 85-86):

A standard criticism of the first stage of [Locke’s] argument is that it seems to commit a rather blatant fallacy, in that from the claim that there must always have been something in existence, it does not follow that there is some one thing that has always existed – it could be that there has instead always been something or other in existence, one thing preceded by another, which was preceded by another, and so on ad infinitum for all of past time, but without any individual one of them having always existed.  Now this objection is not by itself as telling as is often supposed.  Locke could reply that if we think of the series in question as a series of material things, it is highly unlikely that such a series could have kept going for an infinite number of years; eventually, through sheer chance, there would surely have come a point already at which all material things then in existence went out of existence together.  If the only things that exist or ever did exist are such material objects, then, the world would not exist now, for there would, after the point in past time just described, have been nothing left to bring the world back into being once every material thing died out.  So there must in fact be an eternal being which has kept the world in existence continuously.

A rejoinder to such a reply, though, would be to say that this “eternal being” might, for all that has been said, be nothing more than the collection of basic material elements out of which all individual material things are composed.  Even if every particular material object comes into and goes out of existence at some point, the set of fundamental corpuscles (or some suitable candidate from modern physics) as a whole remains in existence throughout.  Of course, Locke would say that this collection of material elements could never by itself generate perception, knowledge, and other mental properties, and I have suggested [earlier in the book] that he has good reason for saying this.

Like Aquinas, Cudworth and Locke can thus be interpreted as allowing for the sake of argument that matter might always have existed, and as then proceeding to argue (also like Aquinas, though working from different metaphysical assumptions) that even if this were the case, matter could not even in principle be the most fundamental everlasting being.  And if someone asks “Why doesn’t Locke make it more explicit that this is what he is doing?” the answer is arguably that establishing that something has always existed was not the step that needed defense in his day.  He could state that part of the argument more loosely because even the atheist of the day would have granted it.  What needed defense was rather the claim that the eternal being could not have been matter – and sure enough, that is precisely the claim that Locke devotes the bulk of the chapter to defending.

That does not mean that Locke’s argument is otherwise unproblematic.  As I go on to say on pp. 86-87 of Locke:

[That matter could never by itself generate mental properties] is consistent with the claim that, wherever the material world got the mental properties that are conjoined with (parts of) it, it has nevertheless existed eternally.  This would be consistent with the idea of a “demiurge,” a god who merely orders preexisting materials into a cosmos, but it would not be consistent with the traditional monotheistic conception of God as a creator who brings the world into existence out of nothing – a conception that is not only the one that Locke happens to want to defend in the Essay, but which is, as we shall see in the next chapter, absolutely crucial to the political philosophy he wants to defend in the Second Treatise of Government.

For Locke to get to the God of traditional monotheism, then, he will have to argue that even an infinitely old collection of basic material components must itself be explained in terms of God’s creative action.  And to do this would seem to require appealing to the idea that matter, being contingent, can only be explained by reference to something that exists necessarily or non-contingently.  But this would in turn require the endorsement of some explanatory principle that could license the inference in question – a principle like the per se causal series of the Scholastics, or the Principle of Sufficient Reason associated with Leibniz and other rationalist philosophers.  As an empiricist, though, Locke would seem to be in no position to advance such a principle.  As noted earlier, Hume and other later empiricists have argued compellingly that if we take seriously the thesis that we can have no idea that is not derived from experience [in the modern empiricist sense of “derived from experience,” I should have added], it seems that we can have no idea of a “necessary connection” between causes and effects, and thus no grounds for any inference to the effect that the material world simply must have its source in some immaterial necessary being, à la Scholasticism and rationalism.  Something similar could be said of the principle Locke appeals to in defense of the claim that the cause of a thing must be the source of its powers – a principle that Locke borrows from his Scholastic predecessors, but which does not sit well with his empiricist scruples.  

If something like Locke’s argument for God’s existence can be defended, then (and there are several contemporary philosophers who would defend an argument for an eternal First Cause of the world), it seems that it will have to be done on the basis of a general metaphysical picture other than the sort allowed for by his empiricism.  Once again, we see that Locke’s attempt to preserve some elements of the Scholastic inheritance while jettisoning others may threaten to force him into a dilemma: in this case, he can either give up a thoroughgoing empiricism and salvage his argument for God’s existence, or follow out the implications of his empiricism and give up the argument. It is not clear that he can have both the empiricism and the argument, though. (Whether some other argument for God’s existence can be defended on empiricist but non-Lockean lines – Berkeley’s argument, for example – is another question.)

However we ultimately judge Locke’s argument, though, the claim that it commits a quantifier shift fallacy does not constitute a fatal objection.

In our final post in this series, we’ll examine the claim that Aristotle commits a quantifier shift fallacy in the Nicomachean Ethics.

Thứ Hai, 4 tháng 7, 2011

For the Thomist, to say that God is the First Cause of things is, first and foremost, to say that He is the cause of their existence at every moment at which they do exist.  God creates things out of nothing precisely in the act of conserving them in being, and apart from His continual causal action they would instantly be annihilated.  You, the computer you are using right now, the floor under your feet, the coffee cup in your hand – for each and every one of these things, God is, you might say, “keeping it real” at every instant.  Nor is this causal activity something anything else could either carry out or even play a role in.  Creation – which for Aquinas means creation out of nothing – can be the act of God alone.

Where creation is concerned, then, God is “first” cause not in the sense of coming before the second, third, and fourth causes, but rather in the sense of being absolutely fundamental, that apart from which nothing could cause (because nothing could exist) at all.  As serious students of the Five Ways know, the sorts of causal series Aquinas traces to God as First Cause are causal series ordered per se, not causal series ordered per accidens.  In the former sort of series, every cause other than the first is instrumental, its causal power derived from the first.  (See this post for more on the subject.)  But where creation is concerned, Aquinas’s talk of intermediate or instrumental causes is only “for the sake of argument”; his point is that even if there were intermediate causes of the being of things, the series would have to terminate in a First Cause.  In fact there is and can be only one Creator and He cannot in principle create through intermediaries.  (That is not to say that God does not work through intermediaries in other respects.  We’re only talking here about His act of causing the sheer existence of a thing or creating it out of nothing.) 

Why not?  Aquinas addresses the question at some length in the Summa Theologiae, the Summa Contra Gentiles, and De Potentia Dei.  The arguments are difficult for someone not versed in the metaphysical presuppositions of Aquinas’s philosophical theology – indeed, some of them are difficult even for someone who is versed in the relevant metaphysics.  But what follows will, I hope, suffice to convey some of the main ideas.  (It will help considerably if the reader has at least some knowledge of such fundamental Aristotelian-Thomistic metaphysical notions as actuality and potentiality, form and matter, and the principle of proportionate causality; of the Thomistic arguments for the existence of God as pure actuality and as being itself rather than merely a being among others; and of the arguments for the uniqueness of anything that is pure actuality and being itself.  This is all spelled out at length in chapters 2 and 3 of Aquinas.)  

First, then, why does Aquinas hold that only God can possibly create out of nothing?

Here’s one way to understand it.  Any of us can easily actualize the potential of the oxygen in the air around us to move, simply by waving our arms.  Only someone with the relevant expert knowledge could take oxygen and hydrogen and synthesize water out of them.  It would take greater power still to cause the prime matter underlying oxygen, hydrogen, or water to take on the substantial form of a tree.  But creation out of nothing requires more power even than that, in fact unlimited power.  For it is not a case of drawing out the potentialities that are already there in a thing, but rather causing a thing to exist entirely, together with its potentialities, where nothing at all had existed before.  It isn’t a case merely of modifying what already exists, but rather of causing to exist in the first place that which all mere modification presupposes.  

Limited causes are limited precisely by potentialities which are not actualized.  Hence a sculptor is limited by the degree of skill he has so far acquired, by the limits on his dexterity given the structure of his hands, etc.  He is limited also by the potentialities of his materials – their capacity to be molded using some tools but not others, their capacity to maintain whatever shape the sculptor puts into them, and so forth.  Now that which creates out of nothing is not limited by any such external factors, precisely because it is not modifying anything that already exists outside of it.  But neither can it be limited by any internal potentialities analogous to the limits on a sculptor’s skill.  For it is not merely causing a being of this or that sort to exist (though it is doing that too) – modifying preexisting materials would suffice to cause that – but also making it the case that any being at all exists.  And only that which is not a being among others but rather unlimited being – that which is pure actuality – can do that.  

The idea is perhaps best stated in Platonic terms of the sort Aquinas uses (in an Aristotelianized form) in the Fourth Way.  To be a tree or to be a stone is merely to participate in “treeness” or “stoneness.”  But to be at all – which is the characteristic effect of an act of creation out of nothing – is to participate in Being Itself.  Now the principle of proportionate causality tells us that whatever is in an effect must be in some way in its cause.  And only that which just is Being Itself can, in this case, be a cause proportionate to the effect, since the effect is not merely to be a tree or to be a stone, but to be at all.  

So only God – who just is pure actuality or Being Itself rather than a being among others – can cause a thing to exist ex nihilo.  But why could He not work through instrumental causes in doing so?  For all the preceding argument would seem to show is that Being Itself is the ultimate cause of any thing’s existing at all.  That is, it suggests that any cause of a thing’s sheer existence that was less than Being Itself would, either directly or indirectly, owe its own existence to that which is Being Itself.  But why couldn’t that which is Being Itself impart to other things their sheer existence through such an intermediary – through an instrumental cause which, like the effect, is merely a being among others rather than Being Itself?

Here’s one way to think about the problem with this idea.  An instrumental cause causes by virtue of being used to alter what already exists, as a chisel is used by a sculptor to alter marble.  But to cause the sheer existence of a thing ex nihilo is not to alter what already exists.  In the case of a material thing, it does not involve causing already existing matter to take on a new form (as a sculptor does), but rather causing the matter and form together to exist.  Hence while it makes sense to speak of using a chisel in the act of sculpting a statue out of marble, it makes no sense to speak of using a chisel in the act of causing a statue to exist ex nihilo.  For before the statue was caused to exist ex nihilo, there was no marble on which the chisel could be brought to bear; and after the statue is caused to exist ex nihilo, there is nothing for the chisel to do, since the marble already is (by hypothesis) a statue.  Now any purported instrumental cause involved in any act of creation ex nihilo would be like the chisel.  It would be a fifth wheel – it wouldn’t be doing anything, and thus would not be causing anything, and thus would not really be an instrumental cause (because not a cause at all).  Hence the very idea of God creating out of nothing through instrumental causes falls apart on analysis.

So, while popular images of God as First Cause have Him knocking down the first domino billions of years ago, and while even Aquinas might seem to make of Him the distant terminus of a regress of simultaneous currently operating causes, nothing could be further from the truth.  God’s relationship to the world is in Aquinas’s view much more intimate than that, indeed, as intimate as possible.  At least where the sheer existence of things is concerned, He and He alone is directly causing them at every instant.  He is, as the Muslims say, “closer than the vein in your neck.” 
For your consideration on this fine Fourth of July:

Editiones scholasticae is a new German publishing venture devoted to publishing works in Scholastic philosophy, including reprints of works which have long been out of print.  Among the first titles announced are reprints of Bernard Wuellner’s two invaluable reference works Dictionary of Scholastic Philosophy and Summary of Scholastic Principles, used copies of which can be expensive and hard to find.  A very worthy enterprise!
