&i;`Georgesçu-Roegen was a truly great economist....This welcome exposition of his major ideas by Beard and Lozada should help economists understand Georgesçu, both the revolutionary boldness and originality of many of his ideas and the careful logic with which he developed them. I believe Beard and Lozada have done an excellent job, both of selection and of exposition....My hope is that this book will do for Georgesçu's ideas what Alvin Hansen did for the ideas of John Maynard Keynes with his A Guide to Keynes&i; published back in 1953. In my view Georgesçu's intellectual contribution will be even greater than that of Keynes.' From the foreword by Herman E Daly, University of Maryland
