<p><strong>"In this collection of theoretically refined and deeply thoughtful essays, Heinz Kurz considers the themes of knowledge and innovation in relation to economic growth, casting great light on the state of contemporary theorizing of these issues – not least, by contrasting modern approaches with those of the classical economists. In a set of concise and elegant subsidiary essays in this volume the analytical character of classical economics is further, and brilliantly, clarified. It should be essential reading for anyone interested in the causes of growth, particularly in relation to the role of innovation, and for those interested in the history of growth theory. Those who perceive themselves as engaged in ‘neo-Schumpeterian’ research programs will have much to learn from this collection." - </strong><em>Tony Aspromourgos, University of Sydney, Australia</em></p>
