“In what way should we understand the claim that there is no evidence for God, or for that matter the claim that there is no evidence for the extra-terrestrial teapot? Since the argument is supposed to be one of analogy, presumably the same notion of evidence is being employed in both cases. But evidence is an extremely slippery concept. We might minimally define it as ‘something that makes us warranted in believing something else’... Further, I presume that when we say there is no evidence for the orbiting teapot, it is empirical evidence we have in mind. So the analogy is meant to be: there is no empirical evidence for either... But
empirical evidence is an extremely slippery concept. Those who place it at the centre of their epistemology tend to either give accounts that are too narrow to be realistic, or too underdescribed to do away with the slipperiness... Nonetheless, we can make do for present purposes with fairly rough, partial characterisations. One such might be: if we can see it, hear it, touch it etc., then we have empirical evidence – indeed the best, most direct kind of empirical evidence there is. This of course goes along with the view that the best examples of really existing things we have are precisely those things we can see, hear, touch etc. This view is common to realists and antirealists in the philosophy of science (e.g. Ernan McMullin and Bas Van Fraassen respectively), for their disagreement is about the status of non-observable things. And it need not imply that all we have evidence for is sense-data themselves, for it can and usually does sit perfectly comfortably with a common-sense conception of seeing, whereby we see tables and chairs, dogs and cats. In any event, ruling out the existence of God on the grounds that God is not a sense-datum would fall prey to the strong medicine principle.
“When we say that there is no evidence for a teapot orbiting the sun, the most plausible interpretation is that no-one, as far as we know, has seen, or touched etc., one. But when we say (those of us who do say it) that there is no evidence for the existence of God, is this what we mean? Atheists such as Dawkins clearly think that certain features of the world – in his case the designedness of organisms –
used to appear to be good evidence for an ‘intelligent creator’. But now, he thinks, we possess a better explanation, so those features no longer appear to be good evidence...
“Clearly, the empirical evidence that Dawkins’ thought once constituted good grounds for believing in God did not consist in seeing, hearing (etc.) God. So there is a common ground between some theists and some atheists – e.g. Swinburne and Dawkins respectively – namely the hardly controversial claim that it is reasonable to affirm the existence of something on empirical grounds other than that someone has seen, heard, etc. that thing...
“But once we admit that it is acceptable to conclude from evidence other than seeing (etc.) a thing, that that thing exists, then a disanalogy between the God case and the teapot case becomes apparent. For, apart from someone seeing it, what
could count as evidence that there was a teapot orbiting the sun?...”

“In both these regards – whether we need to impute causal powers beyond those of objects that just sit there, and whether or not we can say what the object looks like – it is clear that the teapot orbiting the sun lies at one end of the spectrum (or would do, if there was any evidence for such a thing). God, on the other hand, lies at the other end. If there is any evidence for God, it is by means of what God is supposed to have done – which means that that evidence can only be accounted for by God if we impute causal powers to God far above and beyond the ‘power’ to just sit there. And there is nothing that allows us to say what God looks like – if indeed God looks like anything at all. So, when we say that there is no evidence for the teapot, and when we say that there is no evidence for God, we are saying two very different things. In the first case, we are saying that there haven’t been any sightings; in the second we are saying that there is nothing for which God is the best explanation.”

“...There is, I want to argue, a significant difference between denying the existence of a teapot orbiting the sun, and denying the existence of God. When two people disagree over whether or not there is a teapot orbiting the sun, they are disagreeing over whether the world includes that particular item or not. For all that that particular disagreement implies, the two people agree about every other feature of the world: the tea-ist believes in a world that is exactly the same as the one the a-tea-ist believes in, with the single difference that it contains one item that the a-tea-ist’s world doesn’t contain. Since, as I have argued in the previous section, the only thing that could count as evidence for the teapot orbiting the sun is that someone has seen it, it is in one way analogous to a situation where one person says: ‘there’s a postbox at the end of the high street’ and the other person says ‘no there isn’t, go and have a look’, and the first person goes and looks and doesn’t see one. If that person is reasonable, that will be the end of the argument. The two situations are not quite analogous, however, in that no-one has gone and looked to see whether there is a teapot in outer space. But the situations are disanalogous in a second way too, and a way which helps to illuminate why, in the absence of evidence, it is reasonable to conclude that there is no such teapot. That is, that there is nothing
manifestly far-fetched in the idea of there being a postbox at the end of the high street. In the absence of seeing one (leaving aside the possibility of more indirect evidence, such as seeing a map of where all the postboxes are at the GPO) one is hardly being unreasonable if one doesn’t come down on one side or the other. And this difference between the postbox and the teapot tells us something about why it is unreasonable to suspend judgement regarding the teapot, even though we have not only failed to see one, but failed to carry out anything remotely approaching an exhaustive search. Because of its manifest far-fetchedness, or what amounts to the same thing, because it’s reasonable in the absence of prior evidence on the specific hypothesis to estimate that it’s highly unlikely, we can say that, when it comes to teapots orbiting the sun, absence of evidence is evidence of absence. The atheist’s argument attempts to gain persuasiveness by ignoring this issue of prior plausibility. It is true that we cannot (at present) conclusively prove that there’s no teapot in outer space in the way that we could conclusively prove that there’s no postbox on the end of the street by going there and looking. But part of the reason why, despite not being able to do this, it is still reasonable to conclude that there isn’t, is that prior to any investigation the hypothesis is manifestly far-fetched. In the postbox case it is not, and thus we can see that absence of evidence, as far as rendering it reasonable to deny something’s existence goes, has different force depending on the case in hand. Unless the existence of God is taken to be also manifestly far-fetched, the argument to the effect that if we don’t suspend judgement regarding the teapot then we shouldn’t suspend it regarding God, doesn’t get off the ground.
“The atheists might not leave it there, however. It is open to them to simply reply: ‘the existence of God is manifestly far-fetched.’ This seems to leave us in a meta-stalemate – that is, a situation in a contest in which it is impossible to decide whether the outcome is a draw or not. The outcome of the argument so far seems to be meta-agnosticism – that is, the suspension of judgement regarding whether or not one should suspend judgement. But the argument does not end there. For the far-fetchedness of the teapot hypothesis is
by comparison with an alternative – the alternative that there isn’t one. As I have already pointed out, accepting this alternative is nothing more than denying that a particular entity exists. To be analogous, the atheistic alternative would have also to be merely denying that a particular item exists. However, as I now want to argue, it is not.”

“Let us look at a picture of the world as the tea-ist sees it (fig. 1), and at a picture of the world as the a-tea-ist sees it (fig. 2).
“As we can see, these worlds are absolutely identical apart from one item. Where tea-istic picture contains a teapot, the a-tea-istic picture contains nothing. To be analogous, there would have to be a situation where, where the theistic picture contains God, the atheistic picture contains nothing. However, the atheist and the theist are not disagreeing over the presence or absence of one particular entity, but over something that is fundamental to the universe as a whole. As already argued in section 2, the teapot is not the explanation for anything. The hypothesis attributes no actions to it than just sitting there. So, as far as the entire rest of the universe goes, it might as well not be there as be there. So leaving the teapot out of our picture of the world does not require us to explain anything in any way other the than [sic] the way we would have explained it anyway. This is not the case with regard to God. For God is invoked as an explanation for (for example) why the universe exists at all, why it is intelligible, why it is governed by laws, why it is governed by the laws it is rather than some other laws, and doubtless many more things. The atheist is thus committed to more than just the denial of something’s existence, he is committed to there being
some other explanation for all the things that that thing might be invoked to explain. This does not mean that the atheist is committed to
one particular explanation, and neither does it mean that the atheist can’t simply say ‘I don’t know’. But it does mean that the question immediately raises itself, and that the atheist is committed to there being some non-God-involving answer...
“...But in the table, where the theist has God, the atheist has something (even if it’s a ‘something we know not what’) other than God. That something is whatever it is that explains why the Universe has the properties (e.g. the laws) it has. It need not be strictly speaking an
entity – and atheists have sometimes suggested that the universe is self-generating. Still, if we go that way, there must be – even if we don’t know what it is – some explanation of how it is that the universe is self-generating, and more specifically how a self-generating universe comes to have the laws that it has. The worldview that excludes the orbiting teapot, however, does not lack an explanation for anything that the worldview that includes the teapot has an explanation for...”
