Philosophical Skepticism provides a selection of important writings by both skeptics and opponents of the skeptical tradition of Western philosophy. These writings, together with the historical introduction by Landesman and Meeks, clearly illustrate the profound influence that skeptical stances have had on the nature of philosophical inquiry. This collection spans the centuries of skeptical and anti-skeptical arguments, from Socrates to Rorty. It includes selections from the writings of Plato, Diogenes Laertius, Cicero, Sextus Empiricus, Descartes, Hume, Kant, Kierkegaard, Russell, Quine, Nagel, and many others. From this collection, readers will gain a sufficient background to engage in further study of skepticism from both classical and contemporary sources.
