Hart's "Ascription of Responsibility and Rights" is where we find perhaps the first clear pronouncement of defeasibility and the technical introduction of the term. The paper has been criticised, disavowed, and never quite fully redeemed. Its lurid history is now being used as an excuse for dismissing the importance of defeasibility.

This is a collection of essays on themes of legal philosophy which have all been generated or affected by Hart's work. The topics covered include legal theory, responsibility, and enforcement of morals, with contributions from Ronald Dworkin, Rolf Sartorius, Neil MacCormach, David Lyons, Kent Greenawalt, Michael Moore, Joseph Raz, and C.L. Ten, among others.

HLA Hart has sometimes been associated with the false proposition that there is 'no necessary connection between law and morality'. Nigel Simmonds is the latest critic to make the association. He offers an 'ironic' interpretation of a famous passage in Hart's The Concept of Law in which the proposition is apparently rejected as false by Hart. In this paper I explain why, even if Simmonds's ironic interpretation is tenable, it does not associate Hart with the proposition in the way that Simmonds believes that it does. More affirmatively, I show that among several necessary connections between law and morality that Hart defends, there is an important indirect one that runs from law to legality, from legality to justice, and from justice to morality.

In "Action and Responsibility,'' Joel Feinberg pointed to an important idea to which he gave the label "the accordion effect.'' Feinberg's discussion of this idea is of interest on its own, but it is also of interest because of its interaction with his critique, in his "Causing Voluntary Actions,'' of a much discussed view of H. L. A. Hart and A. M. Honoré that Feinberg labels the "voluntary intervention principle.'' In this essay I reflect on what the accordion effect is supposed by Feinberg to be, on differences between Feinberg's understanding of this idea and that of Donald Davidson, and on the interaction between Feinberg's discussion of the accordion effect and his critique of the voluntary intervention principle.
