This book presents and analyzes the most important arguments in the history of Western philosophy's skeptical tradition. It demonstrates that, although powerful, these arguments are quite limited and fail to prove their core assertion that knowledge is beyond our reach.

• Argues that skepticism is mistaken and that knowledge is possible
• Dissects the problems of realism and the philosophical doubts about the accuracy of the senses
• Explores the ancient argument against a criterion of knowledge, Descartes' skeptical arguments, and skeptical arguments applied to inductive inference and self-knowledge
• Uses Moore's proof of an external world and the reliabilist conception of knowledge to illustrate that the traditional skeptical arguments fail to meet their mark.
