 Understood as rational the connection between reason and action cannot be described in terms of any strict law. Yet inasmuch as the connection is also a causal connection, so there must exist some law-like regularity, though not describable in the language of rationality, under which the events in question fall (an explanation can be causal, then, even though it does not specify any strict law). Davidson is thus able to maintain that rational explanation need not involve explicit reference to any law-like regularity, while nevertheless also holding that there must be some such regularity that underlies the rational connection just inasmuch as it is causal. Moreover, since Davidson resists the idea that rational explanations can be formulated in the terms of a predictive science, so he seems committed to denying that there can be any reduction of rational to non-rational explanation.
