What are Theistic <strong>Explanation</strong>s? 51<br />

acting rationally in accepting an apparently inconsistent hypothesis? Most<br />

philosophers would hold that we are not entitled <strong>to</strong> believe such a theory,<br />

which would be equivalent <strong>to</strong> believing a contradiction. 74 But perhaps we<br />

can accept an apparently inconsistent hypothesis, even if we do not believe<br />

it (2.1.3). If it enjoys other explana<strong>to</strong>ry virtues—such as a high degree<br />

of testability, simplicity, on<strong>to</strong>logical economy, <strong>and</strong> informativeness—we<br />

might accept it in the sense of continuing <strong>to</strong> work on it, <strong>to</strong> see if the apparent<br />

inconsistencies can be resolved. As Alan Musgrave remarks, “unless<br />

we are allowed <strong>to</strong> work with logically inconsistent theories, how will they<br />

ever get turned in<strong>to</strong> consistent ones?” 75 (This might entail ab<strong>and</strong>oning the<br />

principle that ex contradictione quodlibet, but a number of logicians have<br />

advocated precisely this move.) So from this point of view, Swinburne’s<br />

proposal is not as objectionable as it might appear at fi rst sight. We could<br />

legitimately adopt a theistic hypothesis, in some provisional, heuristic way,<br />

even if there were some prima facie evidence that it was internally incoherent.<br />

We could do so if it possessed other explana<strong>to</strong>ry virtues. How likely is<br />

it that a theistic hypothesis would possess those explana<strong>to</strong>ry virtues? Once<br />

again that’s a question I shall address later.<br />

3.4 CAUSAL EXPLANATIONS<br />

I have been arguing that a proposed theistic explanation is an intentional<br />

explanation. But theistic explanations are also, it appears, causal explanations.<br />

The God whose existence <strong>and</strong> action they posit is a crea<strong>to</strong>r God,<br />

who brings things in<strong>to</strong> existence by an act of the divine will. But can these<br />

two things be combined? Are intentional explanations causal explanations?<br />

And can we make any sense of the idea that the will of God has causal effi -<br />

cacy? Is the idea of a crea<strong>to</strong>r God a coherent one?<br />

3.4.1 Intentional <strong>and</strong> Causal <strong>Explanation</strong>s<br />

A fi rst objection rests on the very character of intentional explanations.<br />

It suggests that a theistic explanation could not be both intentional <strong>and</strong><br />

causal, since these represent distinct <strong>and</strong> mutually exclusive forms of explanation.<br />

No intentional explanation is a causal explanation. But I believe this<br />

claim <strong>to</strong> be wrong, for reasons I shall outline later (Appendix 1.1). I have<br />

no argument with the idea, defended by Donald Davidson, that intentions<br />

are causes <strong>and</strong> that intentional explanations are also causal explanations. 76<br />

There is one issue that needs <strong>to</strong> be clarifi ed here. I have suggested that<br />

intentional explanations are not nomological (3.2.1). They do, if you like,<br />

depend on something resembling a law, namely the rationality principle.<br />

But they do not depend on law-like generalisations linking particular intentions<br />

<strong>and</strong> particular actions. Does this mean that they cannot be regarded<br />

as causal explanations? Only if you believe that the citing of causal laws is
