82 <strong>Theism</strong> <strong>and</strong> <strong>Explanation</strong><br />
5.1.3 Is Sober Correct?<br />
What are we <strong>to</strong> make of Elliot Sober’s criticisms? Unlike Sober, I am not<br />
using confi rmation theory <strong>to</strong> analyse theistic explanations, for reasons I<br />
have already given (2.1.3.2). Nonetheless, there is much here with which<br />
I would agree. If we are <strong>to</strong> judge a theistic explanation <strong>to</strong> be a potential<br />
explanation, we must be able <strong>to</strong> specify what would follow if it were true.<br />
And we must be able <strong>to</strong> specify this in a way that is independent of the fact<br />
that we know the explan<strong>and</strong>um <strong>to</strong> be true. Given a deductivist account<br />
of intentional explanations (2.1.4), we must be able <strong>to</strong> produce an argument<br />
that has the explanans among its premises <strong>and</strong> a description of the<br />
explan<strong>and</strong>um as its conclusion. I shall refer <strong>to</strong> this as the criterion of independent<br />
specifi cation. 14 Its signifi cance was already recognised by David<br />
Hume. As I noted earlier, Hume posed the question that I shall argue is<br />
central <strong>to</strong> the success of any theistic explanation. “Is the world considered<br />
in general, <strong>and</strong> as it appears <strong>to</strong> us in this life, different from what a man<br />
or such a limited being would, beforeh<strong>and</strong>, expect from a very powerful,<br />
wise, <strong>and</strong> benevolent Deity?” 15 If some fact about the world is not what we<br />
would expect of such a being, then appeal <strong>to</strong> the actions of God cannot be<br />
said <strong>to</strong> explain it.<br />
5.2 The Rationality Principle<br />
But is Sober’s scepticism warranted? Do we need <strong>to</strong> be theological sceptics?<br />
Let’s approach this question afresh. Sober’s objection <strong>to</strong> the design argument<br />
is that it places no constraint on how a putative divine designer might<br />
be expected <strong>to</strong> act. The supposed omnipotence of God—the idea that he<br />
could do anything that is logically possible—merely makes this problem<br />
worse. As he writes, “an engineer who is more limited would be more predictable.”<br />
16 But is this correct? Do proposed theistic explanations place no<br />
constraints on how God might be expected <strong>to</strong> work?<br />
5.2.1 An Explana<strong>to</strong>ry Constraint<br />
I have argued that a proposed theistic explanation is one that views the<br />
explanan dum as the means of achieving a divinely willed goal. More precisely,<br />
it attributes <strong>to</strong> God the desire <strong>to</strong> achieve a particular end, <strong>and</strong> invites<br />
us <strong>to</strong> see the explan<strong>and</strong>um as a means <strong>to</strong>wards this end. It is true that some<br />
proposed theistic explanations may not do this. They may deserve condemnation,<br />
since—as Sober suggests—they merely build in<strong>to</strong> the hypothesis<br />
“the observations we seek <strong>to</strong> explain.” 17 But all this means is that some proposed<br />
theistic explanations are fl awed. It does not mean that all proposed<br />
theistic explanations are fl awed or that no account of divine action could<br />
have any explana<strong>to</strong>ry force. If the theist proposes a divinely-willed goal<br />
<strong>and</strong> suggests that the explan<strong>and</strong>um is the means by which God achieves<br />
this goal, then her proposed explanation does face a constraint. It may not
