This book investigates whether truth can be understood as a fundamental value to provide a radical alternative to naturalistic theories of mental content. Michael Morris, a scholar within the Anglo-American philosophical tradition, challenges the prevailing scientific conception of reality. By analyzing propositional attitudes and the explanation of human behavior, he constructs a framework that moves away from causal theories toward a value-based understanding of the mind's place in the world.

Experts identify this work as a significant contribution to the Oxford Philosophical Monographs series, noting its dense and rigorous engagement with contemporary analytic philosophy. Scholars frequently highlight the text as a challenging counterpoint to established naturalistic orthodoxy in the philosophy of mind.
