<p><strong>'Combining the best of Continental European historical perspective and Anglo-American analytical focus, this is the most challenging inquiry into the rigorous understanding of concepts to be published in recent years.'</strong><em>Mauro Calise, University of Naples and Theodore J. Lowi, Cornell University, authors of Hyperpolitics: An Interactive Dictionary of Political Science</em></p><p><strong>'While much social scientific ink has been spilled over questions of causal inference, such analysis is irrelevant if we do not know what it is we are studying or measuring. Sartori's scholarship is centrally concerned with these challenges, and they are squarely addressed in this book. The volume must be seen in the context of the phenomenally successful resurgence of training in qualitative and multi-method research – and it will be critical for graduate students and scholars not simply in qualitative methods, but also in research design and comparative analysis more generally.'</strong><br /><em>Evan Lieberman, Princeton University</em></p><p><strong>'This is an all-star cast, and the scholarship is outstanding. Sartori is a pioneer in methodology; Collier and Gerring are central figures in the recent renaissance of qualitative methods and have wide experience in presenting technical material to students; and the authors of other chapters are well known for their high-quality scholarship. The book can profitably be read and digested by advanced undergraduates, graduate students, and established scholars.'</strong><em>David Waldner, University of Virginia</em></p><p><strong>'Giovanni Sartori calls for researchers to be ‘conscious thinkers’ who engage deeply with issues of method, yet are not paralyzed by preoccupation with particular techniques. This volume exemplifies Sartori’s approach by bringing together his major essays on concepts and method, along with chapters that show how his framework informs some of the best contemporary social science, and correspondingly yields valuable insights into a series of important substantive topics. Scholars at any stage of their careers should take seriously the insights of this volume.'</strong><em>Melani Cammett, Brown University</em></p><p><strong>'Collier and Gerring have done a great service to the profession by republishing some of Sartori’s seminal contributions on concept analysis (and beyond), together with essays of younger scholars who brilliantly continue his tradition in comparative politics. A timely and important contribution to the debate to social science methodology, this book will be compulsory reading – or re-reading – for comparativists.'</strong><em>Giovanni Capoccia, Professor of Comparative Politics, Oxford</em></p>
