Abstract
This book proposes a reexamination of ancient skepticism with the purpose of both throwing new light on ancient skepticism and contributing to modern epistemological debate. The author hopes to achieve these goals by approaching the ancient texts with a more developed philosophical viewpoint than is found in much historical scholarship, and by showing how the account of ancient skepticism thus achieved is philosophically superior in various ways to modern versions of skepticism. He interprets ancient skepticism as being essentially directed against "realist truth," that is, against the theory that "a claim is true if it corresponds to an objective world that exists independently of the mind". Ancient skepticism is therefore antirealist: it is a mitigated form of skepticism which admits an antirealist conception of truth, "arguing that our beliefs are necessarily relative to human nature and perception, the culture we live in, philosophical commitments, and so on". Ancient skeptics are thus much nearer to modern antirealists than would be the case if their skepticism were unmitigated, as is frequently claimed in modern work on ancient skepticism. Interpreted as antirealism, ancient skepticism turns out to present certain philosophical advantages as compared to modern forms of antirealism.
