50 <strong>Theism</strong> <strong>and</strong> <strong>Explanation</strong><br />
literally. They say, for instance, that God is a “person” who “knows” things<br />
<strong>and</strong> can “bring about” states of affairs. 70 If such propositions are in fact<br />
coherent, it can only be because such language is being used analogically.<br />
But precisely because such language is being used analogically, we cannot<br />
directly demonstrate its internal coherence, since we cannot specify exactly<br />
what it does <strong>and</strong> does not mean. This might appear <strong>to</strong> constitute a fatal<br />
objection <strong>to</strong> a theistic hypothesis: if we cannot demonstrate its coherence,<br />
why should we accept it? Swinburne’s response is that we can establish<br />
the coherence of theism indirectly, by showing that there is good reason <strong>to</strong><br />
believe that there exists a God who has these apparently incompatible properties.<br />
71 And, of course, Swinburne has devoted much of his life <strong>to</strong> arguing<br />
for the existence of the Christian God.<br />
Does this offer the theist a way out? Well, perhaps the charge of incoherence<br />
is not fatal (3.3.4), but Swinburne underestimates its seriousness. I<br />
shall argue later that Swinburne’s arguments for the existence of God are<br />
best thought of as abductive arguments (6.1.3). But if someone is offering<br />
an abductive argument, then it seems vital that his hypothesis be consistent.<br />
The reason is simple, <strong>and</strong> will become clear if we call <strong>to</strong> mind Peirce’s<br />
schema for abductive reasoning (2.1.2).<br />
(1) The surprising fact, E, is observed.<br />
(2) But if H were true, E would be a matter of course,<br />
(3) Hence, there is reason <strong>to</strong> suspect that H is true.<br />
A potential explanation, I argued, is one that satisfi es the second premise<br />
of this schema. The key question in each case is: What would follow, if H<br />
were true? But it is a well-known principle of at least classical logic that<br />
from a contradiction anything follows: ex contradictione quodlibet, in its<br />
traditional Latin formulation. 72 Let’s say, for the sake of the argument, that<br />
the theistic hypothesis (H) does embody a contradiction. (If this were true,<br />
we could easily be unaware of it, especially if the language we are using is<br />
being used analogically.) Let’s say, for instance, that God simply could not<br />
be both perfectly just <strong>and</strong> perfectly merciful, but that our theistic hypothesis<br />
attributes both qualities <strong>to</strong> him. Then whatever the explan<strong>and</strong>um is, we<br />
could derive from H a proposition describing it. For the same reason, we<br />
could apparently corroborate H by appealing <strong>to</strong> any fact whatever. 73 But this<br />
is equivalent <strong>to</strong> saying that a self-contradic<strong>to</strong>ry hypothesis could never be an<br />
acceptable explanation. While we have reason <strong>to</strong> doubt the consistency of<br />
the theistic hypothesis, we have reason <strong>to</strong> treat it with some suspicion.<br />
3.3.4 The Consistency Requirement<br />
It follows that we should not underestimate the seriousness of the charge<br />
of internal incoherence. But neither should we overestimate it, for it may<br />
not be a fatal objection. Are there circumstances in which we would be
