"This book provides a unique retrospective analysis of the development of modern theories of human reasoning, written by an eminent researcher, from a perspective gained over 40 years as a leading reasoning scientist. A must read for researchers just starting out, and a fascinating read for all students of reason." - Valerie Thompson, University of Saskatchewan, Canada"Jonathan Evans is the leading British investigator of the psychology of reasoning. This book tells the whole story of the development of the field from his days as a young researcher in the late 1960s up to the present day. It is indispensable reading for those new to the field and to the ‘old hands’." – Philip Johnson-Laird, University of Princeton, USA"Reader, prepare yourself for a Reasoning Feast in this book. The papers of Jonathan Evans have virtually defined the reasoning field for the last thirty years. From classic papers on the selection task, to some of the best work ever on belief bias, to the latest on dual process theory and the Great Rationality Debate, Evans was there to define the issues for us in ways that were uniquely productive." - Keith E. Stanovich, University of Toronto, Canada
