No one who has read either Rawls's Political Liberalism or my An Essay on Rights can fail to profit from the penetrating analysis to which Peter Jones has subjected them.

Disposed to agree with most of what he says about the former, I am also inclined – but as yet unable – to disagree with much of what he says about the latter. However, alongside his many acute criticisms on which I'll need to reflect further, Jones's report of two key moves in my argument requires some revision and may, therefore, warrant this brief early response.
