This book investigates the paradoxes of irrational thought and action, specifically focusing on the mechanisms of self-deception and the failure of self-control. David Pears, a distinguished philosopher, constructs a unified framework to analyze how individuals act against their own better judgment. By synthesizing classical philosophical inquiry with modern psychological research, Pears examines the tension between conscious intent and irrational behavior. He evaluates the contributions of thinkers ranging from Aristotle to Freud to provide a rigorous account of why human beings frequently defy the dictates of reason.

Experts and reviewers recognize this work as a foundational and highly lucid treatment of the complexities surrounding irrationality. Readers frequently note the academic rigor of the prose, which successfully bridges the gap between traditional philosophy and cognitive psychology.
