Dawkins et al bring us into disrepute - By Michael Ruse

Dr. Michael Ruse, an atheist philosopher of biology, speaks out against the "New Atheists".

The New Atheists

As a professional philosopher my first question naturally is: "What or who is an atheist?" If you mean someone who absolutely and utterly does not believe there is any God or meaning then I doubt there are many in this group. Richard Dawkins denies being such a person. If you mean someone who agrees that logically there could be a god, but who doesn't think that the logical possibility is terribly likely, or at least not something that should keep us awake at night, then I guess a lot of us are atheists. But there is certainly a split, a schism, in our ranks. I am not whining (in fact I am rather proud) when I point out that a rather loud group of my fellow atheists, generally today known as the "new atheists", loathe and detest my thinking. Richard Dawkins has likened me to the pusillanimous appeaser at Munich, Neville Chamberlain. Jerry Coyne, author of Why Evolution is True, says (echoing Orwell) that only someone with pretensions to the intelligentsia could believe the silly things I believe. And energetic blogger PZ Myers refers to me as a "clueless gobshite" because I confessed to seeing why true believers might find the Kentucky Creationist Museum convincing. I will spare you what my fellow philosopher Dan Dennett has to say about me.

There are several reasons why we atheists are squabbling – I will speak only for myself but I doubt I am atypical. First, non-believer though I may be, I do not think (as do the new atheists) that all religion is necessarily evil and corrupting. This claim is on a par with golden plates in upstate New York. The Quakers and the Evangelicals were inspired and driven by their religion to oppose slavery, and a good thing too. Of course there has been evil in the name of religion – the pope telling Africans not to use condoms in the face of Aids – but as often as not religion is not the only or even the primary force for evil. The troubles in Northern Ireland were surely about socio-economic issues also, and the young men who flew into the World Trade Centre towers were infected by the alienation and despair of the young in Muslim countries in the face of poverty and inequalities.

Second, unlike the new atheists, I take scholarship seriously. I have written that The God Delusion made me ashamed to be an atheist and I meant it. Trying to understand how God could need no cause, Christians claim that God exists necessarily. I have taken the effort to try to understand what that means. Dawkins and company are ignorant of such claims and positively contemptuous of those who even try to understand them, let alone believe them. Thus, like a first-year undergraduate, he can happily go around asking loudly, "What caused God?" as though he had made some momentous philosophical discovery. Dawkins was indignant when, on the grounds that inanimate objects cannot have emotions, philosophers like Mary Midgley criticised his metaphorical notion of a selfish gene. Sauce for the biological goose is sauce for the atheist gander. There are a lot of very bright and well informed Christian theologians. We atheists should demand no less.

Third, how dare we be so condescending? I don't have faith. I really don't. Rowan Williams does as do many of my fellow philosophers like Alvin Plantinga (a Protestant) and Ernan McMullin (a Catholic). I think they are wrong; they think I am wrong. But they are not stupid or bad or whatever. If I needed advice about everyday matters, I would turn without hesitation to these men. We are caught in opposing Kuhnian paradigms. I can explain their faith claims in terms of psychology; they can explain my lack of faith claims also probably partly through psychology and probably theology also. (Plantinga, a Calvinist, would refer to original sin.) I just keep hearing Cromwell to the Scots. "I beseech you, in the bowels of Christ, think it possible you may be mistaken." I don't think I am wrong, but the worth and integrity of so many believers makes me modest in my unbelief.

Fourth and finally, I live in the American South, surrounded by ardent Christians. I want evolution taught in the schools and I can think of no way better designed to make that impossible than to spout on about religion, from ignorance and with contempt. And especially to make unsubstantiated arguments that science refutes religion. I never conceal my nonbelief. I defend to the death the right of the new atheists to their views and to their right to propagate them. But that is no excuse for political stupidity. If, as the new atheists think, Darwinian evolutionary biology is incompatible with Christianity, then will they give me a good argument as to why the science should be taught in schools if it implies the falsity of religion? The first amendment to the constitution of the United States of America separates church and state. Why are their beliefs exempt?

Back in 1961, in the depths of the cold war, terrified as we were by the threat of nuclear annihilation, John Whitcomb Junior and Henry Morris published The Genesis Flood, a six-day-creationist account of origins. Because of its dispensationalist message – God clears things out every now and then, as he did at the time of Noah, and we should expect the next (literal) blow up fairly shortly – it became the fundamentalist bible. But don't worry. It's all part of God's plans, even the Russian bomb. Today, nearly a decade after 9/11, terrified as so many still are by the terrorist threat, the atheistic fundamentalists are finding equally fertile soil for their equally frenetic messages. It's all the fault of the believers, Muslims mainly of course, but Christians also. But don't worry. In the God Delusion, we have a message as simplistic as in The Genesis Flood. This too will solve all of your problems. Peace and prosperity await you in this world, if not the next.

Forgive me if I don't sign on.

Is Absence of Evidence, Evidence of Absence? Part 2

Continued from Part 1

4. Some Examples: Tooth Fairies, Leprechauns, Santa Claus, Teapots, and Invisible Objects

Let me see if I can put all this together to answer your question with some examples which are thought to pose a problem for the line of thought defended thus far. Your question basically was when absence of evidence counts as evidence of absence. Answering this will depend upon whether our epistemic situation satisfies the Evidence Expectation and Knowledge Expectation Criteria for the object in question: Should one expect to possess evidence sufficient to know that object O exists? If a rhino were in the room, then the answer is “Yes.” Thus, looking about and seeing no rhino, that itself is evidence there is none present.

But what about things like the Tooth Fairy, leprechauns, and Santa Claus? Atheists claim they don’t need to disprove God for the same reason they don’t need to disprove the existence of Tooth Fairies, leprechauns, and Santa Claus. The problem with the comparison with the last two items is that, while our epistemic situation regarding God doesn’t always satisfy the Evidence Expectation and Knowledge Expectation Criteria, our epistemic situation regarding leprechauns and Santa Claus does — we can, and do, disprove them all the time; it’s just that there are few, if any, people arguing for their existence so we’re never called upon to give those reasons. If Santa existed we should expect to see, but don’t, lots of evidence of that fact, including warehouses at the North Pole, a large sleigh, and so forth; similarly, were there biologically tiny human beings on this planet we should expect to see, but don’t, their evidence: miniature villages, waste products, the bones of their deceased — evidence similar to what we have for mice, hamsters and other small critters. If there were more people today who made a case for leprechauns and Santa Claus then it would be entirely appropriate for us to enter into dialogue with them, giving reasons for their non-existence.

At this point an atheist might object that the Tooth Fairy is different from leprechauns and Santa Claus because she’s invisible. (Is she invisible in the story?) Suppose she is invisible. According to the tale she collects teeth left under children’s pillows leaving behind a reward (usually money). Evidence we should expect to see if she existed then would be money left behind, stolen teeth, etc. Do we find such evidence? Well, no we don’t, but we would expect to if she existed. So, even the Tooth Fairy satisfies the Evidence Expectation and Knowledge Expectation Criteria. So because we lack evidence of her, we say she doesn’t exist (sorry kids!).

Suppose the atheist agrees that the reason why we deny Tooth Fairies, leprechauns and Santa Claus is because we do have evidence for their absence. He might nonetheless insist that the situation is significantly different for other objects which are causally isolated from us. A case in point is Russell’s famous teapot which circles about the sun, an object which is (for the most part) causally isolated from us. Do we need to be agnostic about it? Can we say it doesn’t exist? I think we know it doesn’t exist because it wasn’t put there by the Russian or American astronauts; and we know that matter in the universe does not self-organize into teapot shapes. So really, we have a great deal of evidence that Russell’s teacup doesn’t exist; and since our discussion is confined to cases where we infer the non-existence of something simply on the basis of absence of evidence for it, the example is irrelevant.

Another Objection and a Reply

But now imagine the atheist objecting:

OK, very well, I grant everything you say thus far about Santa Claus, and all the rest; but we don’t have to abide by your Criteria when it comes to objects which are both invisible (like the Tooth Fairy) and causally undetectable (like the teapot). For example, an invisible floating, pink elephant over my head. There’s no such thing.

The theist could reply:

Your example is charming and rhetorically clever but incoherent. Can something that is invisible even be an elephant? If so, then it surely isn't very much like a normal elephant— a massive, material object which exhibits all sorts of physical properties. Your “invisible elephant” question is really just a rhetorically clever sleight of hand; the question doesn’t make much sense in the first place and perhaps should be rephrased as something like: "Do we know there are not immaterial things around us?" to which the answer should be "No" in either of two senses: (i) No, because we have no evidence that there are not immaterial things, or (ii) No, because there are immaterial things around us, e.g. God, angels, immaterial minds, qualia, abstract objects like numbers or propositions, etc.9

Is Absence of Evidence, Evidence of Absence? Part 1

By Shaun

1. Introduction

The famous British philosopher Bertrand Russell was asked what he would say if he found himself before God on Judgment Day and God said to him, “Why didn’t you believe in Me?” Russell shot right back: “Not enough evidence, God! Not enough evidence!”

Many have taken what they consider to be an apparent lack of evidence for God as evidence that God doesn’t exist; that is, they look around, don’t see “enough” evidence and conclude that atheism is true.

But Russell realized that the inference from apparent lack of evidence for God to atheism is fallacious. That’s why in his famous debate in 1948 with Frederick Copleston he preferred the label “agnostic” instead of “atheist.” Yet today, many call themselves “atheists” when really they are agnostics.

Let’s first define some terms around the question “Does God exist?”

"Does God exist?"

Theism: "God exists"

Non-theism: "I don't believe in God"

 

Agnosticism: “I don’t know if God exists”

Atheism: “God does not exist”

Hard Agnosticism: "I don't know
if God exists and no one else can
know either."

Soft Agnosticism: "I don't know
if God exists, but it's possible for
someone to know."

Notice a few things about these definitions. First, non-theism and agnosticism are not mutually exclusive because you could be a non-theist and so fail to believe in God (i.e., you could lack belief in God) but you might also be an agnostic saying, “For all I know, God exists. I just don’t know.” Notice also how extreme hard agnosticism is, since it claims even more than atheists do; the hard agnostic says that everyone is wrong, both atheists and theists, and that they cannot know what they claim, even if they have apparently sound arguments! Little wonder, then, that hard agnosticism is sometimes called “ostrich agnosticism!”

There are sound arguments for God’s existence. Some of them are very good. But suppose it were not so; suppose all the arguments for God fail and there are no further good reasons to believe in God. What follows?—Atheism? It’s very important to realize that the answer to this question is NO. What follows is, at most, soft agnosticism.


2. When Does Absence of Evidence = Evidence of Absence? (Or, when is the inference from “I see none” to “there is none” valid?)

What I have said so far raises the question, When does the absence of evidence become evidence of absence? This is a good question because sometimes (but not always) the former implies the latter. Let’s start with some examples to work with.

Example 1. Elephants in the Room (Absence of Evidence = Evidence of Absence)
Someone asks, “Are there any elephants in the room?” After looking about and seeing none, I say, “No, I see none. There are no elephants in the room.”

The inference from “I see none” to “There are none” in this example is justified. With respect to elephants in this room, I’m not agnostic; rather, I positively affirm: There are no elephants in the room. In this case, absence of elephants in the room is evidence of their absence. But this inference doesn’t hold for Example 2.

Example 2. The Grand Canyon Fly (Absence of Evidence ≠ Evidence of Absence)
We’re standing atop the Grand Canyon and someone asks, “Is there a fly way down there?” After a quick glance I say, “No, I see none. There is no fly down there.”

As in the last example we move from “I see none” to “There is none”—but unlike the last example the conclusion is unjustified. Agnosticism regarding the fly is the appropriate response here. So in the Elephant Example we don’t have to be agnostics, but in the Grand Canyon Fly Example we do. Why? Notice that it is not the relative size of the object which creates the difference (The zookeeper might have asked you on your zoo trip, “Do you think an elephant is in the cage in the next room?” to which your reply might be agnosticism: “I have no idea. Maybe.”)

The salient difference between these two examples has entirely to do with your epistemic situation — which is, roughly, the extent and limits of your ability to know something through your primary sources of knowing (i.e. perception, memory, introspection, testimony, etc.) — and the fact that only in one situation (Elephants in the Room) do we expect to have knowledge which we lack. My epistemic situation regarding knowing whether an elephant is in the room is quite good, while my epistemic situation regarding knowing whether a fly resides at the bottom of the Grand Canyon is quite poor. Why? When are we in an epistemically good situation in order to say, “There is no X”? What conditions have to be met? At least two. In the absence of evidence of an object O you may deny that O exists only if these Criteria are met:

Evidence Expectation Criterion. If an object O existed, then we would expect there to be evidence for it.

Knowledge Expectation Criterion. If there were evidence of object O, then we would expect to have knowledge of the evidence.

In short, in the absence of evidence, we can deny the existence of something O only if we should expect to possess evidence sufficient to know that O exists but in fact lack it.

To prove his position the atheist has his task cut out for himself: What he must do is show that (a) the epistemic situation in which we find ourselves with respect to belief in God’s existence satisfies the above Criteria; and (b) demonstrate that we lack sufficient evidence for knowing that God exists. Equivalently, he must show that all the arguments for God are unsound and then argue that if God existed then we would expect to be in a position to know whether God exists. But as we’ll see, there is good reason to think (a) is false because our epistemic situation in which we find ourselves with respect to belief in God’s existence does not satisfy the above Criteria.
