Book excerpt: Critical theory, characteristically linked with the politics of theoretical engagement, covers the manifold of the connections between theory and praxis. This thought-provoking Research Handbook captures the broad range of those connections as far as legal thought is concerned and retains an emphasis both on the politics of theory, and on the notion of theoretical engagement. The first part examines the question of definition and tracks the origins and development of critical legal theory along its European and North American trajectories. The second part looks at the thematic connections between the development of legal theory and other currents of critical thought such as; Feminism, Marxism, Critical Race Theory, varieties of post-modernism, as well as the various ‘turns’ (ethical, aesthetic, political) of critical legal theory. The third and final part explores particular fields of law, addressing the question how the field has been shaped by critical legal theory, or what critical approaches reveal about the field, with the clear focus on opportunities for social transformation.
