"However one casts up the balance-sheet on Wallerstein’s second volume, his effort commands respect and justifies interest in the volumes to follow."
—W.W. Rostow, Society
"An exciting and highly intelligent book...The staggering pace at which Wallerstein moves over different levels of explanation, and skillfully combines them into his argument, deserves admiration."
—Henry Kamen, History
"In this age of high specialization, Wallerstein's ambitious but judicious synthesis will command the respect of any scholar who has tried to grapple with the peculiarly intractable problems of this period.:...the book is shot through with shrewd and often stimulating comment."
—Charles Wilson, Journal of Modern History
