 Davidson holds that events are particulars such that the same event can be referred to under more than one description. He also holds that events that are causally related must be related under some strict law. However, since Davidson takes laws to be linguistic entities, so they can relate events only as those events are given under specific descriptions. Thus, as was already evident in Davidson’s approach to the theory of action, the same pair of events may instantiate a law under one description, but not under others. There is, for example, no strict law that relates, under just those descriptions, the formation of ice on the surface of a road to the skidding of a car on that road, and yet, under a different description (a description that will employ a completely different set of concepts), the events at issue will indeed be covered by some strict law or set of laws. But while nomological relations between events (relations involving laws) depend on the descriptions under which the events are given, relations of causality and identity obtain irrespective of descriptions – if the icing-up of the road did indeed cause the skid, then it did so no matter how the events at issue are described. (The form of description – whether mental or physical – is thus irrelevant to the fact that a particular causal relation obtains). It follows that the same pair of events may be related causally, and yet, under certain descriptions (though not under all), there be no strict law under which those events fall. In particular, it is possible that a mental event – an event given under some mental description – will be causally related to some physical event – an event given under a physical description – and yet there will be no strict law covering those events under just those descriptions. My wanting to read Tolstoy, for instance, leads me to take War and Peace from the shelf, and so my wanting causes a change in the physical arrangement of a certain region of space-time, but there is no strict law that relates my wanting to the physical change. Similarly, while any mental event will be identical with some physical event – it will indeed be one and the same event under two descriptions – it is possible that there will be no strict law relating the event as described in mentalistic terms with the event as physically described. In fact, Davidson is explicit in claiming that there can be no strict laws that relate the mental and the physical in this way – there is no strict law that relates, for instance, wanting to read with a particular kind of brain activity.
