In Retaking Rationality, Richard L. Revesz and Michael A. Livermore argue convincingly that one of the least understood-and most important-causes of our failure to protect the environment has been a misguided rejection of reason. The authors show that environmentalists, labor unions, and other progressive groups have declined to participate in the key governmental proceedings concerning the cost-benefit analysis of federal regulations. As a result of this vacuum, industry groups have captured cost-benefit analysis and used it to further their anti-regulatory ends. Beginning in 1981, the federal Office of Management and Budget and the federal courts have used cost-benefit analysis extensively to determine which environmental, health, and safety regulations are approved and which are sent back to the drawing board. The resulting imbalance in political participation has profoundly affected the nation's regulatory and legal landscape. But Revesz and Livermore contend that economic analysis of regulations is necessary and that it needn't conflict with-and can in fact support-a more compassionate approach to environmental policy. Indeed, they show that we cannot give up on rationality if we truly want to protect our natural environment.

Retaking Rationality makes clear that by embracing and reforming cost-benefit analysis, and by joining reason and compassion, progressive groups can help enact strong environmental and public health regulation.
