The Fragmentation of Reason

Preface to a Pragmatic Theory of Cognitive Evaluation


In recent years, leading cognitive psychologists have painted a detailed, controversial, and highly critical portrait of commonsense reasoning. Stephen Stich undertakes a spirited defense of this work and puts forth a critique of those writers who argue that widespread irrationality is a biological or conceptual impossibility.

Stephen Stich is Professor of Philosophy at Rutgers University and author of From Folk Psychology to Cognitive Science.


"All psychologists concerned with reasoning will find that Stich's reflections on it deepen their understanding of the topic.
Richard E. Nisbett, Contemporary Psychology

"It is a book which has many of the merits prized by philosophers of the analytic school: lucidity, terseness, wealth of argument, respect for the findings of empirical science, and - dare one say it - all the appearances of an honest commitment to the pursuit Of truth."
E. J. Lowe, Philosophical Quarterly
