This introduction provides a very brief sketch of the fundamental claims of Arthur Ripstein's Force and Freedom before locating the criticisms of his interlocutors in relation to those claims. Valentini and Sangiovanni are situated as critics of the Kantian frame, while Ronzoni and Williams are critics situated within that frame.

This paper develops a domination-based practice-dependent approach to justice, according to which it is practices of systemic domination which can be said to ground demands from justice. The domination-based approach developed overcomes the two most important objections levelled to alternative practice-dependent approaches. First, it eschews conservative implications and hence is immune to the status quo objection. Second, it is immune to the redundancy objection, which doubts whether empirical facts and practices can really play an irreducible role in grounding justice. In (...) theorising dominating practices in terms of practices of social power, a domination-based approach makes justice dependent on factual information in three ways: First, the principle of non-domination is indeterminate and can only be spelled out by taking into view particular contexts of domination. Second, the principle of non-domination is conditional on the existence of practices of social power. Third, social power possesses a structural ontology – to know whether A has social power over B we need to turn to social rules distributing agents' higher order status of normative authority towards each other. This explains in what way practices of social power – and of domination – are both factual and normative practices and hence how such practices are non-redundant in grounding justice. (shrink)
