In 2011, despite continued developments in forecasting, tracking, and warning technology, the United States was hit by the deadliest tornado season in decades. More than 1,200 tornadoes touched down, shattering communities and their safety nets, and killing more than 500 people—a death toll unmatched since 1953.

Drawing on the unique analysis described in their first book, Economic and Societal Impacts of Tornadoes, economists Kevin M. Simmons and Daniel Sutter here examine the factors that contributed to the outcomes of such tornadoes as the mid-April outbreak that devastated communities in North Carolina, the “Super Outbreak” across the southern and eastern United States in late April, and the single, mile-wide funnel that touched down in Joplin, Missouri, in late May. In the course of their study the authors identify patterns and anomalies, and reconsider previous assertions about the effectiveness of the Doppler radar and storm warning systems. Their conclusions, as well their assessment of early recovery efforts, are aimed at helping community leaders and policy-makers keep vulnerable populations safer in the future.

Alan Gewirth's Reason and Morality, in which he set forth the Principle of Generic Consistency, is a major work of modern ethical theory that, though much debated and highly respected, has yet to gain full acceptance. Deryck Beyleveld contends that this resistance stems from misunderstanding of the method and logical operations of Gewirth's central argument. In this book Beyleveld seeks to remedy this deficiency. His rigorous reconstruction of Gewirth's argument gives its various parts their most compelling formulation and clarifies its essential logical structure.

Beyleveld then classifies all the criticisms that Gewirth's argument has received and measures them against his reconstruction of the argument. The overall result is an immensely rich picture of the argument, in which all of its complex issues and key moves are clearly displayed and its validity can finally be discerned.

The comprehensiveness of Beyleveld's treatment provides ready access to the entire debate surrounding the foundational argument of Reason and Morality. It will be required reading for all who are interested in Gewirth's theory and deontological ethics and will be of central importance to moral and legal theorists.
