Skepticism, as a philosophical school of thought, has endured for over two millennia not by offering certainties, but by persistently questioning them. This audiobook is an exploration of skepticism—not as a rejection of knowledge, but as a method of inquiry, a disciplined doubt, and a guide for navigating the boundaries of belief and understanding.

From its roots in ancient Greece to its reverberations in modern epistemology and science, skepticism has played a crucial role in shaping the intellectual history of the West. Figures like Pyrrho, Sextus Empiricus, and later René Descartes and David Hume, each in their own way, questioned the reliability of perception, the trustworthiness of reason, and the foundations of knowledge itself. But skepticism is not monolithic. There are radical skeptics, who doubt the possibility of knowledge altogether, and mitigated or academic skeptics, who temper doubt with practical engagement in the world.

This audiobook does not aim to champion skepticism as the final philosophical stance, nor to dismiss it as an intellectual dead end. Instead, it presents skepticism as a vital tradition that serves an indispensable role in philosophy: it compels us to re-examine our assumptions, to clarify our justifications, and to resist the seduction of easy answers. In a world increasingly saturated with information and opinion, skepticism reminds us that the mere possession of data does not equate to wisdom—and that humility in the face of uncertainty is a virtue, not a weakness.
