'With great clarity and originality, Kyle Johannsen redirects our view of current discussions about social justice. By asking us to consider substantive debates as based on conceptual disagreements, he opens up new paths for philosophical research in a highly productive and inspiring way.' — Rainer Forst, Professor of Political Theory and Philosophy, Goethe University Frankfurt'A fascinating book showing how disagreement about what justice requires often reflects confusion or disagreement about the very concept of ‘justice’. More controversially, it argues, with great clarity and rigor, that there is a particular way in which the concept of justice should be understood and used.' — Patrick Tomlin, Associate Professor in Political Philosophy, University of Reading'Johannsen’s monograph not only helps clarify our thinking on this conceptual question but also charts where important debates in the literature have gone astray because of diverging implicit assumptions about the concept of justice.' — Kristin Voigt, Dialogue'Johannsen offers an interesting and original diagnosis of recent disputes in political philosophy about the nature of justice and the proper domain of judgements of justice.' — Colin M. Macleod, Dialogue
