"In recent years the discussion of imperialism has become so compartmentalized that it is difficult for somebody who is not directly involved to put the often polemical discussion and the various scientific and political positions forward into a relevant context. Mommsen's survey is an excellent guide."—German Studies, on the German edition. "Theories of Imperialism is the most succinct, fairest, and most sophisticated statement I have seen of the range of theories of imperialism. Each set of theorists is come at in their own terms, described fairly, and summarized fully. The book is objective, readable, and short."—Robin W. Winks, Yale University
