This volume investigates the multifaceted nature of rationality by examining its role across philosophy, economics, psychology, and law. Editors Alfred R. Mele and Piers Rawling curate twenty-two original chapters from prominent scholars who synthesize existing research while advancing new arguments. The text serves as a comprehensive framework for understanding how different disciplines define and apply the concept of rational behavior and decision-making.

Experts identify this handbook as a foundational reference for students and researchers navigating the complex intersection of cognitive science and philosophy. Readers frequently note the academic density of the prose, which is tailored for those seeking a rigorous survey of contemporary rationalist discourse.
