Key Thinkers – serie

Globalization: Key Thinkers offers a critical commentary on the leading thinkers in the contemporary globalization debate, as well as new arguments about the future direction of globalization thinking. The book guides the reader through the key arguments of leading thinkers, explaining their place in the wider globalization debate and evaluating their critical reception. Eleven thematic chapters focus on one or two key thinkers covering every aspect of the globalization debate including the theoretical arguments of Anthony Giddens and Manuel Castells, to the positive arguments of Thomas Friedman and Martin Wolf and the reforming ideas of Joseph Stiglitz. Other chapters variously address the ideas of Immanuel Wallerstein, Arjun Appadurai, Paul Hirst, Naomi Klein, Grahame Thompson, David Held, Anthony McGrew, Michael Hardt, Antonio Negri, Saskia Sassen and Peter Dicken. Each chapter also provides some carefully selected recommendations for further reading for the thinkers discussed. The book ends with a concluding chapter that examines how thinking about globalization is likely to develop in future. Whilst individual chapters can stand alone, the book is designed as a whole to enhance the reader's understanding of how different thinkers' ideas relate and contrast to each other.

Over twenty two centuries ago, the Greek general Pyrrhus questioned the real gains of military victory. Today we might reflect on the recent wars in Iraq and Afghanistan in much the same way. War is not only cruel but capricious; its outcomes are often bitter and frustrating, even for the winning side. Strategy: Key Thinkers expertly introduces the ideas of major strategic thinkers whose work explores the complex challenges associated with the use of military force. Early chapters deal with the foundational work of Sun Tzu (Sunzi), Thucydides, Vegetius, Machiavelli and Carl von Clausewitz and their relevance to problems facing Western militaries today. The book then considers broader issues, such as the distinctive importance of air and maritime operations, the difficulty of waging offensive land warfare in the face of modern firepower, the implications of nuclear weapons, and the potential of irregular warfare. It concludes by highlighting key themes which connect - and distinguish - the works under consideration, noting how these similarities and differences can inform the strategic debates of the early twenty-first century.
