This book also provides a good introduction to recent work in evo- lutionary psychology stimulated by the work of Tooby and Cosmides as well as to work about biases and heuristics in the mold of Kahneman and Tversky.3 Given the award of the 2002 in to Vernon L. Smith (who has been a pioneer in the ªeld of reviewed in this book) and to Kahneman (who has chal- lenged many of the underpinnings of the rational-choice model), schol- ars in all of the social sciences would be well advised to read this book carefully.4 Elinor Ostrom University

The Health of Nations: Infectious Disease, Environmental Change, and Their Effects on National Security and Development. By Andrew T. Price-Smith (Cambridge, Mass., MIT Press, 2001) 219 pp. $22.95 In this book, Price-Smith advances the argument that the prevalence of infectious diseases has a direct impact on state capacity. As such new pathogens as hiv and Ebola emerge, and such old diseases as tuberculosis and Malaria reemerge in more virulent forms, outbreaks are likely to have a devastating impact on the capacity of states. Citing historians such as McNeill, Price-Smith argues that this relationship between health and state capacity has always existed, but he suggests that the current increas- ing rate of global environmental degradation will have a dramatically negative effect on the health of nations in the near future, speeding up and enhancing the nature of crises.1 As a result, he posits a declining abil- ity on the part of states to address the different problems, resulting in growing global insecurity and conºict. He concludes with the policy recommendation that Western governments should devote more atten- 3 Leda Cosmides and John Tooby “Cognitive Adaptations for Social Exchange,” in J.

The book’s great strength is the wealth of anecdotal evidence ad- duced on behalf of this thesis. In particular, several chapters paint a dev- astating portrait of the economic and social effects of diseases on low- income economies. Much of this material has already emerged in bits and pieces elsewhere, but Price-Smith’s presentation has the merit of

The work is not as strong about causal mechanisms. Its main ex- planatory instrument is a series of dubious national bivariate regressions between problematical proxies for disease and state capacity. The author moves incautiously from correlation to causality on too many occasions, making grand claims about the impact of health on state capacity, as if many other causal mechanisms were not also at work. Finally, the link between health and national security is asserted rather than demon- strated in the book’s ªnal chapters. The thesis that the security of Western countries, such as the , should lead them to as- sist countries in African that are ravaged by hiv/aids is an immensely at- tractive one, since our hard-headed publics do not appear swayed by humanitarian reasons alone. It is unfortunate that this book fails to make the empirical case for such an interest. Nicolas van de Walle Michigan State University

Hellenicity: Between Ethnicity and Culture. By Jonathan M. Hall (Chicago, University of Chicago Press, 2002) 312 pp. $50.00 In a famous passage (Histories, 8.144), Herodotus has the Athenians chas- tise the Spartans for fearing that Athens might capitulate to the Persians. Several deterrents, according to the Athenians, keep them from betray- ing Greece—the places of worship that the Persians had destroyed and the elements constituting a “common Greekness” (to Hellenikon)— common blood and language, common shrines to the gods, common sacriªces, and common customs. This seems to be straightforward testi- mony to the ancient Greek conception of Hellenic ethnicity, but Hall demonstrates that communally shared Panhellenic identity was unstable and, at most times, less salient than other collective identities, especially in pre-classical Greece apart from Athens. This study traces the formation of a collective Hellenic identity in Greek antiquity, referring throughout by neologism to ancient Greek ethnic consciousness as “Hellenicity.” Hall begins by setting out his methodological and theoretical positions on the study of ethnic identity. For him, ethnicity represents a constructivist “imagined community,” not any primordial Stammbaum, and ethnicity “denotes both the self- consciousness of belonging to an ethnic group (‘ethnic identity’) and the
