'The contributions are informed, up-to-date and lucid, and many of them make unusual - in fact, unprecedented - efforts to present opposing viewpoints fairly and to look at what they have in common rather than at what divides them … The mixture of detached overviews and strongly argued positions works very well, in my view, and the editor is to be congratulated for the high standards that are maintained throughout. The tremendous intellectual energy and excitement of the field come through strongly, and I shan't hesitate to recommend many of the chapters to students.' The Times Higher Education Supplement
