Few thinkers can have had a more diverse or a more contested impact on theorizing law than Michel Foucault. This diversity is reflected in the wide range of Foucault's work and of the intellectual fields it has so conspicuously influenced. Such diversity informs the present collection and is signalled in the headings of its four sections: Epistemologies: archaeology, discourse, Orientalism; Political philosophy: discipline, governmentality and the genealogy of law; Embodiment, difference, sexuality and the law; and, the subject of rights and ethics. Whilst the published work selected for this collection amply accommodates this diversity, it also draws together strands in Foucault's work that coalesce in seemingly conflicting theories of law. Yet the editors are also committed to showing how that very conflict goes to constitute for Foucault an integral and radical theory of law. This theory ranges not just beyond the restrained and diminished conceptions of law usually derived from Foucault, but also beyond the characteristic concern in Jurisprudence and Legal Philosophy to constitute law in its difference and separation from other socio-political forms.
