This book investigates the philosophical paradox of akrasia, or weakness of the will, to understand why individuals knowingly choose actions contrary to their better judgment. J. C. B. Gosling, a noted scholar of ancient philosophy, evaluates historical frameworks from Plato, Aristotle, and the Stoics to identify the limitations of traditional accounts of irrationality. By synthesizing these classical perspectives, the author proposes a contemporary model for analyzing human decision-making and the nature of intentional action.

Scholars frequently cite this work as a rigorous examination of the historical development of ethical theory regarding human agency. It is widely regarded as a foundational text for those seeking to understand the intersection of ancient philosophy and modern psychological inquiry into irrationality.
