  This is just what Donald Davidson set out to do in a rich, elegant,  and incisive paper published in 1970 which has had a towering  influence on the subsequent literature. Davidson’s treatment aims to  vindicate the possibility of weakness of will; to offer a novel  analysis of its nature; to clarify its status as a marginal, somehow  defective instance of agency which we rightly find dubiously  intelligible; and to do all this within the contours of a general  view of practical reasoning and intentional action which assigns a  central and special role to our evaluative judgments. Let us see how  he proposes to do these things.
