Appendix 163<br />

causal laws do exist. They do not cover the relevant events described as<br />

reasons, but they do cover the same events described in some other way—<br />

“neurological, chemical, or physical.” 66 So propositions (1), (2), <strong>and</strong> (3) are<br />

compatible.<br />

Against Davidson. The principal objection <strong>to</strong> Davidson’s view is that it<br />

apparently reduces reasons <strong>to</strong> epiphenomena, stripping them of their causal<br />

status. 67 After all, Davidson has argued that we can speak of a cause only<br />

where there exists a law. But he has also argued that there are no laws<br />

governing events when these are described in the vocabulary of beliefs,<br />

desires, <strong>and</strong> intentions. It follows that we cannot speak of an intention as a<br />

cause. In other words, given the truth of propositions (1) <strong>and</strong> (2), proposition<br />

(3)—Davidson’s causal thesis—must be false. So our three propositions<br />

really do represent an inconsistent triad. Assuming that we want <strong>to</strong><br />

maintain (2) <strong>and</strong> (3), then we need <strong>to</strong> ab<strong>and</strong>on (1). We need <strong>to</strong> ab<strong>and</strong>on a<br />

nomological view of causation.<br />

If this objection is correct, then the key question is not an epistemic<br />

one regarding explanation; it is a metaphysical question regarding causation.<br />

And we cannot answer the epistemic question without answering the<br />

metaphysical one. If we claim that there exist lawless causal explanations,<br />

we are implicitly claiming that there can be causes that do not instantiate<br />

(actual) regularities. I am inclined <strong>to</strong> think that this is not a problem, that<br />

we are not bound <strong>to</strong> a nomological view of causation (4.2.1). But do we<br />

need <strong>to</strong> say this? Is the objection correct?<br />

In defence of Davidson. Let me restate Davidson’s position. What he<br />

wants <strong>to</strong> say is that there can exist two descriptions of an event, one which<br />

is (if you like) “physical” <strong>and</strong> one which is intentional. If we describe the<br />

event using the language of the natural sciences, we can see that there exist<br />

law-like regularities, the kinds of regularities that are essential <strong>to</strong> the existence<br />

of causation. (Let’s grant Davidson this latter assumption, for the<br />

sake of the argument.) But if we describe the event using the language of<br />

intentional explanations, there are no laws <strong>to</strong> which we can appeal. Does<br />

this mean that we cannot speak of an intention as a cause, given Davidson’s<br />

assumption about causality? No, it does not. For both descriptions<br />

refer <strong>to</strong> the one event, <strong>and</strong> it is on the level of the event that there exists (or<br />

does not exist) a cause. After all, causation is a feature of the world, not a<br />

feature of our descriptions of it. The following argument is invalid, since<br />

it embodies a form of the representational fallacy. 68 It assumes (wrongly)<br />

that we can deduce the structure of the world from the language we use<br />

<strong>to</strong> describe it.<br />

(1) Causation involves law-like relations.<br />

(2) Intentional explanations do not cite causal laws.<br />

(3) Therefore intentional explanations are not causal explanations.
