Abstract

Although seemingly a purely negative position without any implications, scepticism is more often seen to lead to two entirely different prescriptive political and moral conclusions, either liberal or illiberal. This article explains how such opposing conclusions derive from insufficient attention to: the instability of scepticism, its tendency to collapse into varieties of unquestioned belief; its underdetermined character, since it is always expressed as a variable mixture of doubt and beliefs, which are often neither acknowledged nor recognized; and insufficient clarity about the motivational power of social or political theory generally.
