bad arguments

1755 Lisbon earthquakeThe Problem of Evil is a pretty difficult one for Christians and other theists. One response to it is to say that atheists have a problem too, either because they also must cope in a world with so much evil and suffering in it, or because without a way to “ground” morality, they have no basis to call anything evil. As we’ll see, these are both Bad Arguments.

Bad argument: Atheists must cope psychologically with evil, and this is a problem for them

Stephen Law dealt with the response that atheists must also cope with the evil and suffering in the world (which actually came from an agnostic, not a theist, in the linked example). As Law says, this sort of response relies on shifting the problem we’re talking about to the problem of how to cope psychologically with evil and suffering (which is indeed a problem for both theists and atheists). But this is not the problem that the discussion was originally about, which is that evil and suffering make theism less likely to be true (i.e. they’re evidence against it), but are not evidence against atheism.

Bad argument: Atheists have no grounds to call anything evil and so cannot make an argument from evil

Wintery Knight and Cornelius Hunter are both Christians, and both make the second sort of argument: if there is no God, they say, there is no matter of fact about what is evil, it’s an entirely subjective judgement either of particular individuals or of human societies, and as such cannot be binding on God.

Firstly, both Knight and Hunter just assert that if there is no God, there are no moral facts1. But in fact the philosophical debate about whether there are moral facts is carried on largely without reference to God: there are atheists who say there are, and atheists who say there aren’t, and a lot of debate about just what it means for something to be an objective moral fact anyway. Apologists like to pick an atheist who says there aren’t moral facts and quote them as defining The Atheist View on Moral Facts, as if there were only one.

But suppose for the sake of argument that Knight and Hunter are right, and if there is no God, there are no moral facts. Conventional Christianity still faces a problem of evil as an internal contradiction. Here’s a little argument from evil:

1. If God exists, God is objectively morally perfect.
2. If God exists, it is objectively morally imperfect for someone to permit human suffering which it is in their power to alleviate (see the Parable of the Good Samaritan, for example).
3. There is human suffering which it would be in God’s power to alleviate, were God to exist.

Now, assume for the sake of argument that God exists. From 3, suffering which it is in God’s power to alleviate exists. From 2, God is objectively morally imperfect, but this contradicts what we get from 1. So God does not exist, proof by contradiction.

Any theist worth their salt will attack premise 2 (and probably say that there should be a “without good reason” after the “permit”, and then say that God either has good reasons or that we have no way of knowing that he doesn’t). But my purpose isn’t to present a comprehensive argument from evil, but rather, to point out the shape of the argument: notice that the argument does not rely on a claim that there are in fact objective moral values, only that if God exists, there are, something which Knight and Hunter agree with. In fact, more robust arguments from evil generally rely on putting together statements which theists should accept and showing that they lead to the conclusion that there is no God.

A couple of Knight’s commenters (1, 2) point this out to him (one even explicitly telling him that the Argument from Evil is what’s known as a reductio ad absurdem) but he just doesn’t seem to get it. I hope you do, but let me know if this could be clearer.


  1. Along with the claim that if there is a God, he’d provide a grounding for moral facts, which seems dodgy, see previous discussion 

“It’s arrogant to claim to be an atheist, since you can’t know that God (or gods) does not exist. It’s much more intellectually respectable to be an agnostic.”

I’ve come across that sort of claim in a couple of places on the net recently. What could it mean? Time for another post in the series on bad arguments.

Bad argument: Atheists must show beyond all doubt that ChristianGod or MuslimGod doesn’t exist

Perhaps the speaker is some sort of conventional believer, like a Christian or a Muslim or whatever. They think that it’s up to someone calling themselves an “atheist” to demonstrate with that the Christian (or Muslim) God doesn’t exist, and do it so convincingly that there’s no possibility that the atheist could be mistaken. It seems the theist is either saying the atheist has got something wrong, or saying that nobody should call themselves an atheist.

Say that an atheist thinks that the Christian God probably doesn’t exist. The theist might claim that the atheist has acted wrongly in ignoring Christianity’s claims on them, because this is only “probably”, not “certainly”. But the theist’s claim relies double standard, since nobody else is held to that standard of certainty before they’re allowed to act on a belief (the conventional theist certainly isn’t). Possibly what’s going on here is that the theist thinks the atheist should be more like them: it looks like there are believers who argue the mere possibility that their belief is true justifies their continued faith. I’ve talked about the “virtue” of faith and discussed whether God might be fond of soft cheese before, so I won’t go into that again here.

(The famous atheists who are often called arrogant don’t claim certainty, of course.)

Perhaps the theist doesn’t think the atheist has been unreasonable (given the atheist thinks it’s unlikely that God exists, it’s fair enough that they don’t go to church or whatever), but thinks that people who haven’t attained certainty shouldn’t be defined as “atheists”. Luckily, the theist doesn’t get to define atheism.

Bad argument: An atheist must deny the existence of anything that anyone has ever called a god

“Well, I’ll say it simple: a god is someone with enough power to say ‘I am a god’ and make other people agree. Mortal wizard, lich, emperor, dragon, giant, leftover bit of chaos… it doesn’t really matter what it is underneath. What matters is that it has the strength to enforce its claims.”
– Rebel Theology, from Tales of MU (Tales of MU is basically “50 Shades of Advanced Dungeons and Dragons”, so be advised that some parts of the book are sexually explicit, although the linked chapter isn’t)

If The Man’s definition of a god is the one we’re using, it’s much more likely that there are gods (pretty certain, in fact, since people have probably convinced other people of their godhood at various points in history).

Spot the godThere are people who identify gods with love or the feeling they get from looking out into the night sky or with the quantum vacuum (trigger warning for physicists: linked post contains quantum woo-woo). In these cases it seems fine for the self-described atheist to say “that isn’t what I meant” or “I don’t dispute that those things might/do exist, but it seems silly to call them gods”.

Some statements which look as if they’re claims about the existence of gods end up saying nothing more than an atheist might say, with some god-talk tacked on purely as decoration. As Simon Blackburn’s lovely (and short) piece on Hume’s Dialogues Concerning Natural Religion has it:

Philo the sceptic says that we cannot understand or know anything about a transcendent reality that explains or sustains the ongoing order of nature, while the theists like Demea say that we cannot understand or know anything about the transcendent reality, which is God, that explains or sustains the ongoing order of nature. Since the inserted clause does not help us in the least, the difference between them is merely verbal.

Cleanthes, the intelligent design theorist in the book, says that complete mystics are “atheists without knowing it”. Since some sophisticated theologians, like Hume’s Demea, call themselves theists, perhaps Cleanthes is a bit presumptuous. You can see his point, though: it’s odd that someone might be called a theist though they only differ from an atheist in calling some mysterious thingy “God”. Perhaps we should be a bit more resistant to the idea that anyone can “identify as” anything: that way lies Tumblr.

But we perhaps we shouldn’t assume that even people who go to church and say the Creed are assenting to a set of propositions (previously) or that their expectations of what will actually happen differ from those of an atheist (previouslier). If we still call those people theists, why not Demea?

Anyhoo: Philo and Demea are both agnostics (“we cannot … know”) about something, but just because Demea has called it “god”, it’s not clear that Philo couldn’t justly claim to be an atheist (though in the book, he doesn’t, of course).

Good argument: you can’t know what’s out there

Philip Pullman said:

Can I elucidate my own position as far as atheism is concerned? I don’t know whether I’m an atheist or an agnostic. I’m both, depending on where the standpoint is.

The totality of what I know is no more than the tiniest pinprick of light in an enormous encircling darkness of all the things I don’t know – which includes the number of atoms in the Atlantic Ocean, the thoughts going through the mind of my next-door neighbour at this moment and what is happening two miles above the surface of the planet Mars. In this illimitable darkness there may be God and I don’t know, because I don’t know.

But if we look at this pinprick of light and come closer to it, like a camera zooming in, so that it gradually expands until here we are, sitting in this room, surrounded by all the things we do know – such as what the time is and how to drive to London and all the other things that we know, what we’ve read about history and what we can find out about science – nowhere in this knowledge that’s available to me do I see the slightest evidence for God.

So, within this tiny circle of light I’m a convinced atheist; but when I step back I can see that the totality of what I know is very small compared to the totality of what I don’t know. So, that’s my position.

This seems fair enough. But often criticism of atheists is phrased like this:

Bad argument: you can’t know that there isn’t an X out there

where “an X” is some particular thing which would be hard to detect, like an immaterial being who made stuff but then doesn’t intervene, say. The problem with this is that the speaker hasn’t got enough evidence to even suggest X. Sure, we can’t rule out X, but what about Y or Z or a vast number of other possibilities? Why mention X as something special to be agnostic about? Often it’s because X looks like a god from a conventional religion, tweaked to be even less detectable. But that’s no reason to think that X is especially likely to exist. The error here is called privileging the hypothesis.

To anticipate a possible objection: a lot of people saying “I believe in X” may provide evidence to differentiate it from Y and Z. But we need to be careful about what X is here, as the range of things that people refer to as “god(s)” is pretty wide. Some gods (the conventional theist ones) have a whole lot of believers but have good arguments against their existence, so claims that an atheist who accepts those arguments should call themselves agnostic about those gods seem to be you must prove it beyond doubt arguments. “I believe in gods which are invisible gremlins in the quantum foam: you can’t show that those don’t exist” is privileging the hypothesis.

There’s an atheist bad argument which runs something like this: “Faith is believing stuff without evidence, believing stuff without evidence is always bad, therefore faith is bad”.

This seems reasonable at first, but sooner or later you meet a William Lane Craig or similar apologist type, as Jerry Coyne did recently:

Craig argues that science itself is permeated with assumptions about the world that cannot be scientifically justified, but are based on faith. One of these is the validity of inductive reasoning: “Just because A has always been followed by B every time in the past is no proof at all that A will be followed by B tomorrow.” To suppose the latter requires faith.

According to Coyne, as well as the problem of induction, Craig mentions last-Thursday-ism and the idea that we’re all in the Matrix as beliefs that we reject on faith. Some of commenters on Coyne’s blog react as if Craig is advocating these ideas that we all reject, that is, as if he really thinks that the Sun might not rise tomorrow or that we’re in the clutches of a cartesiandaemon. But that’s not Craig’s point. Nor is Craig being inconsistent if he gets on an aeroplane assuming that the laws of physics will carry on working as they always have to keep it flying. After all, he’s not the one claiming that it’s always wrong to believe things without evidence.

The problem here, which makes the atheist’s argument a bad one, is that the atheist has cast their net too broadly. Craig is right to say that there are things that atheists (and everyone else) believe “on faith”. To say that these beliefs are always unwarranted leaves the atheist open to Craig’s counter-argument that, to be consistent, the atheist should then discard those beliefs or admit that it’s not always wrong to believe things without evidence.

Doing better

Nevertheless, something has gone wrong with Craig’s argument if it’s supposed to be a defence of religious faith (as all Craig’s arguments ultimately are). Religious faith is different from belief in induction or the existence of an external world. The atheist should abandon the claim that unevidenced beliefs are always bad, and concentrate on the distinction between religious beliefs and, say, the belief that the external world is real.

One way of doing that would be to turn Craig’s allegation of inconsistency back on him. As Chris Hallquist puts it

belief in the Christian God isn’t very much at all like most of the common-sense beliefs commonly cited as threatened by Descartes & Hume-style skepticism (like belief in the reliability of our senses), but is an awful lot like beliefs most Christians wouldn’t accept without evidence – namely, the beliefs of other religions.

The atheist’s discomfort is now the apologist’s: either he must accept that, say, Muslims or Scientologists are right to take things on faith (in which case, why not join up with them instead?); or further distinguish his religion from theirs (probably by making arguments about the resurrection of Jesus). The atheist’s acceptance of the real world doesn’t come into it.

Hume’s own solution to radical scepticism was to note that he couldn’t entertain that sort of thing for long. Creatures like us soon fall unavoidably back on treating other people as if they were conscious, the world as if it were real, and so on. The great man tells us:

Most fortunately it happens, that since reason is incapable of dispelling these clouds, nature herself suffices to that purpose, and cures me of this philosophical melancholy and delirium, either by relaxing this bent of mind, or by some avocation, and lively impression of my senses, which obliterate all these chimeras. I dine, I play a game of back-gammon, I converse, and am merry with my friends; and when after three or four hours’ amusement, I wou’d return to these speculations, they appear so cold, and strain’d, and ridiculous, that I cannot find in my heart to enter into them any farther.

Among educated folk, thoughts of gods rely on meetings with other believers to keep them going: believers are chronic sinus sufferers. They rarely anticipate the world being any different from a godless one, and those who act as if God is real are called crazy even by their fellow believers. To be sure, that doesn’t mean their avowed beliefs are false. But again, they are not like the commonplace beliefs that everyone takes on faith. In my experience, they fly forgotten, as the dream dies with the dawning day. How about a nice game of backgammon?

Edit: gjm11 suggests another reasonable response in this comment: admit that believing stuff without evidence is bad, and try to minimise it, and say that the problem with religious faith (in so far as that means holding unevidenced beliefs) is that it means having way more unevidenced beliefs than necessary.

Edit again: I’ve also commented with a shorter version of this on Coyne’s original posting, so there’s some discussion there too.

This round of bad arguments is about science. Before I start, I’ll acknowledge my debt to Jeffrey L. Kasser’s lectures, though, of course, any mistakes in applying them to the question of science and religion are my own.

Most people recognise science’s effectiveness at modelling the world, and theists are no exception. Some theists disagree with well established conclusions of science (for example, evolution). Some theists go along with the folk in liberal arts faculties who, in Kasser’s phrase, think science is a particularly dull literary genre. I’m not going to talk about either of these sorts of people. This post is about theists who claim their religion is compatible with, but has gone “beyond”, science. Their claims usually rely on making true, but uninteresting, arguments, in the hope that the hearer slides to a stronger conclusion than the arguments warrant.

Science has not explained X, therefore God did it

This is the God of the gaps argument. Right now, popular choices for X are abiogenesis, consciousness, and altruism. To take that last example, Francis Collins argues that the theory of evolution has no explanation for pure altruism, and, following C.S. Lewis’s Argument from Morality in Mere Christianity, claims that the Christian God must be responsible. As the former director of the Human Genome Project, Collins’s opinions carry weight, but, poking around with Google Scholar, I found no evidence that he has contributed his criticisms to the peer reviewed literature on the evolution of altruism. Even if he had written a good paper on that subject, more is needed before we accept that the best alternative explanation is a particular god. As Gert Korthof’s review of Collins’s book puts it “Collins fails to demonstrate a. the failure of Darwinism to explain the Moral Law (true altruism) b. the divine origin of the Moral Law c. b follows from a.”

Science cannot investigate/explain/prove everything

There’s a bad argument from atheists which leads to confusion here. Some atheists seem to use “science” to mean “anything for which there’s good evidence”, but the theists, quite sensibly, use it to mean “that stuff scientists do”. If the theist faces an atheist who says “your religion is invalid because it cannot be established by science”, it’s legitimate for the theist to dispute that statement by talking about other, non-scientific, forms of evidence which most people accept.

There are some things we do not use science to investigate, because they seem a poor fit for scientific investigation. To use one of Kasser’s examples, we wouldn’t get into a scientific investigation of the “universal law” that “all the beer in my fridge is American”, even if that is a statement which has the form of a scientific law (“all copper conducts electricity”). I prefer to distinguish scientific evidence from other rational evidence (though I think these forms of evidence have something in common which is not shared by religious “ways of knowing”): Eliezer Yudkowsky’s article on the subject describes what I mean.

So, the theists are at least partially right, but notice that none of this says much to convince us that there’s a God. When they try to do that, theists typically say that science or other rational evidence will get you some way towards theism (though, I’d say, not all that far), but then add that some “other way of knowing” or “faith” is required in addition. But if the theist claims they have another “way of knowing”, they must demonstrate its reliability, rather than merely knocking existing ways of knowing.

Science cannot prove your wife loves you, but you believe that, don’t you?

A specific case of the “science cannot explain everything” argument, this particular example gets its own section because it’s regularly trotted out by people who ought to know better (for example, John Lennox in his debate with Richard Dawkins). Again, this is one is true, but uninteresting. It’s not the job of science to prove my wife loves me, just as it’s not the job of science to explore my fridge looking for American beer. Nevertheless, assuming I’m not actually a stalker, I have sufficient rational evidence that my wife loves me, and I don’t have to invoke any special ways of knowing to get it.

Next time

Next time, we’ll look at claims that science arose from theism, and talk about reductionism and butter.

To give the impression that I’m fair and balanced, this time round I’m looking at a bad argument which is usually used by atheists.

There’s a scene The West Wing where President Bartlet tears a strip off an evangelical Christian talk radio host. In the scene (you can see it on YouTube, or read a transcript), the evangelical tells Bartlett that the Bible says homosexuality is an abomination. Bartlet then launches into a series of rhetorical questions, asking how he should carry out other Old Testament rules which we’d now find ridiculous, if not downright evil: “My chief of staff, Leo McGarry, insists on working on the Sabbath. Exodus 35:2 clearly says he should be put to death. Am I morally obligated to kill him myself or is it okay to call the police?”

Let’s call this the Barlet gambit: the President’s argument seems to be that it’s inconsistent for evangelicals to say “homosexuality is wrong because the Bible says so”, because they’re not also keeping these other rules which are also found in the Bible. The gambit is a favourite with people who argue with evangelicals about homosexuality: sometimes they even quote Bartlet.

Unfortunately, the Bartlet gambit fails as an argument.

What’s wrong with it

Evangelical Christians have reasons why they’re not keeping the Old Testament laws despite regarding the Old Testament as scripture. The question comes up in the New Testament itself, once we reach the Acts of the Apostles, where we read of the first non-Jews converting to Christianity (up to that point in the story, what will later become Christianity is still a movement within Judaism, although a few Gentiles are impressed with Jesus in the gospels). The Council of Jerusalem ruled that Gentile Christians are allowed to eat shrimp and wear mixed fibres and, luckily for penis owners, don’t have to be circumcised.

So, according to Acts (which, like the rest of the Bible, is inerrant, remember), Christians sorted this stuff out in the first century AD. They aren’t going to worry about atheists calling them hypocrites for wearing cotton/polyester blend while “hating the sin and loving the sinner”.

Perhaps Barlet is specifically objecting to the evangelical’s use of Leviticus, which does put homosexuality on a par with things which aren’t kosher, rather than with things which are morally evil. Alas, even without Leviticus, there are other Bible passages which can be pressed into service against the gay, and you can rely on evangelicals to know most of them, because the issue has become a defining feature of evangelicalism. We could argue that these passages don’t apply to modern committed homosexual partnerships, but evangelicals don’t find these arguments impressive.

What to do instead

In the UK, many rank-and-file evangelicals are educated professionals. They didn’t get into religion to give gays a hard time, and, unless they’ve completely disappeared up their own sub-culture, they tend to be a bit embarrassed by the anti-gay stuff. Still, because it’s “what the Bible says”, they feel they’re obliged to go along with it anyway, even if the Guardian wouldn’t approve (the evangelical jargon phrase for that sort of thing is that it’s a “hard teaching” where you’ll just have to “trust God”).

If I were a gifted orator like Barlet, I think I’d appeal to their sense of justice. Is there perhaps something odd about the way churches accept straight couples who are openly in their second or later marriage (something about which Jesus had some strong words to say), but wouldn’t be happy with an openly gay couple? Some hypocrisy there, maybe?

Or we might try empathy. There’s the problem that, as Valerie Tarico says, evangelicalism “can re-direct our mother-bear instincts away from protecting vulnerable individuals and toward protecting the ideology itself. Believers may come to feel more protective of their religion than they are of actual human beings.” Still, it might be worth a go: is it fair to say that gay people cannot form committed romantic relationships? Imagine yourself in their shoes. If you obey the evangelical rules, it seems rather a lonely place.

There’s an awful lot of nonsense talked about religion and atheism, from both sides of the fence. Today, I’m looking at a specific set of theist (usually Christian) arguments, namely, those related to “worldviews“. Fear not, though, theism fans: this is the start of a series on bad arguments, and the atheists have it coming too…

Note: the section titles here are links which should take you straight back to the section. So if you find someone playing “Spot the Worldview” online, you can link them straight to this page to show them the error of their ways.

Slightly less difficult

As I’ve mentioned before, talk of worldviews became fashionable among evangelicals when I was an undergraduate. Back then, one of the big evangelistic events the Christian Union organised was called Paradigm Shift, a term borrowed from Thomas Kuhn’s book The Structure of Scientific Revolutions. As part of our evangelism training, we read Nick Pollard’s book, Evangelism made slightly less difficult, which was about helping people to see the flaws in worldviews other than Christianity (Pollard writes about this approach here).

There were some good things about this approach. Engaging with the arguments of people who disagree with you is better than writing those arguments off as a smokescreen put up by evasive sinners. It’s more realistic than the major alternative approach, which was (and still is) treating Two Ways to Live as inherently magical, so that the most important thing was to “proclaim” it to non-Christians as often as possible. Still, worldview talk can go wrong. Here are some ways I’ve seen that happen:

Worldview X is false, therefore my preferred rival, Y, is true

This is an example of the false dilemma fallacy. As gareth_rees says, theists may assume (but not show) that the worldview they’re proposing does better than a major rival, and spend all their time attacking the rival. In creationists’ attempts to disprove evolution, there’s an implicit assumption that if evolution fails, the Christian God is the next preferred explanation. Similarly, much apologetical effort is directed against materialism or physicalism, when it is perfectly possible to be an atheist and believe in ghosts, say. Matt McCormick’s useful article, Know Your Godless Heathen Positions, makes clear the distinctions between a number of possible positions (atheism, materialism, naturalism, and so on).

This is not a fallacy if an atheist is, say, a committed materialist who won’t accept religion for that reason. In that case, a theist would need to clear the ground by arguing against materialism. The fallacy occurs when, having cleared the ground, the theist fails to build their own argument.

Spot the Worldview

We all have views about how the world is, but many theists assume that all atheists bought a well-known brand that’s available in bulk (as Christianity itself is, albeit in a variety of sizes, colours and flavours). A while back, on this thread, many theists seemed to assume that all atheists would be strict materialists. That’s not how I’d describe myself: I’d say I’m a provisional materialist, at best.

Sometimes, theists assume they can argue against these atheist brands merely by mentioning their names and saying that everybody knows brand X is inferior. For example, you might be in the middle of talking about Dawkins’s books when a theist tells you that “Richard Dawkins is a logical positivist, and positivism has been debunked”. This doesn’t work on it’s own: first they have to show that Dawkins is a logical positivist (he’s not, he’s a scientific realist), then they have to give some argument against positivism, and lastly show it’s relevant to an argument about whether his books are any good.

Everything is a faith position, atheism is a religion

Evangelical Christians like to argue (wrongly) that “everyone worships something”. This translates into worldview talk as statements like “everything is a faith position: I have faith in God, you have faith in human reason/science/the Conservative Party”. You might hear the theist make a statement like “atheism is a religion”. What could they mean by this?

They might mean that everyone has to start by assuming some stuff (that they’re not in the Matrix, say, or that scientists aren’t just making their results up), assuming stuff you can’t show is “faith”, therefore everyone has “faith”, and therefore Christian faith is as justified as any other. This goes wrong in a couple of ways: firstly, it assumes that all such assumptions are equally reasonable. They aren’t: for example, they can be differentiated by how easily we could tell if they were wrong. Edited: Chris Hallquist puts it better than I did, when he says that “belief in the Christian God isn’t very much at all like most of the common-sense beliefs commonly cited as threatened by Descartes & Hume-style skepticism (like belief in the reliability of our senses), but is an awful lot like beliefs most Christians wouldn’t accept without evidence–namely, the beliefs of other religions. That kind of response is very hard to reject without special pleading on behalf of Christianity, and doesn’t involve commitment to any potentially troublesome epistemic principles.”

Secondly, this use of “faith” isn’t how many Christians like to use the word. According to Christians, faith means putting your trust in a person. Christianity transplants notions of loyalty to friends onto loyalty to worldviews. With the exception of those of us who worship at the Church of Dawkins, atheism isn’t about loyalty to or trust in a person, nor is steadfastness in a particular atheist view seen as a virtue (quite the reverse, as far as I’m concerned).

They might mean that there are atheists who, for example, organise into groups to further their aims, or raise funds for the cause. As Poke argues, even atheists may feel they should not organise into groups because “that’s what religion does”. The atheists should recognise that doing the opposite of what mistaken people do doesn’t make you correct. The theists should recognise that forming into groups and raising money is not what makes something a religion.

Finally, they might mean that atheists imitate the worst features of religion. This could be true: both religious and non-religious groups may fall into uncritical supercriticality, the idea that it’s wrong to criticise any argument that supports your position. It would be right for a theist to criticise an atheist group which fell into this trap, but not all of them do so.
