"Peter Paret's small book is masterfully constructed. He has set out to 'consider specific events' without losing sight of the general issues they exemplify."--Thomas Rid, Weekly Standard "Given the importance of the topic and Paret's exceptional expertise, his new book on 1806 must arouse considerable interest... If this handsome little book does not fulfill the need for a comprehensive study of the Prussian reform, it does provide a brief, intelligent, and artful recapitulation of some of the period's major themes."--Eugenia C. Kiesling, Michigan War Studies Review "The Cognitive Challenge of War offers a welcome alternative to the usual historiographic ping-pong about the War of the Fourth Coalition... Rather than weighing in on the traditional arguments about skirmishers and linear tactics or the corps d'armee system, Peter Paret has offered an intriguing bridge between social history and military history."--Sam A. Mustafa, Journal of Military History "[ E]xperts of the subject and readers of Paret's earlier works will not find many new insights in this short book, but for them and for everybody who is interested in the subject, it offers an excellent and elegantly written overview on Prussia in 1806 and the responses to the defeat of its army."--Karen Hagemann, Journal of Central European History "A valuable study for anyone interested in the Napoleonic era, military reform, or the Prusso-German military experience."--A. A. Nofi, Strategy Page "[ T]his book is a major achievement that few historians could even have tried to undertake, and the reader will be richly rewarded by the unusually comprehensive perspective and the many compelling insights. Anybody interested in Prussian history of the nineteenth century, Napoleonic military history, military and strategic theory, or the history of military innovation will find the price well worth paying."--Claus Telp, European History Quarterly "Paret writes profoundly on the Prussian military reforms and on the ideas that underpinned them... His greatest success ... is in revealing [ the] linkage ... between the ideas of the military reformers, Clausewitz amongst them, and the broader cultural trends at the turn of the eighteenth and nineteenth centuries."--Michael Rowe, European Review of History "Paret's achievement in this elegant extended essay is to show how On War emerged not just from the wreckage of Jena-Auerstadt, but also from the political, social, artistic, and literary context in which it was conceived."--Alex Roland, ISIS
