Presumption and the Practices of Tentative Cognition

Presumption is a remarkably versatile and pervasively useful resource. Firmly grounded in the law of evidence from its origins in classical antiquity it made its way in the days of medieval scholasticism into the theory and practice of disputation and debate. Subsequently it extended its reach to play an increasingly significant role in the philosophical theory of knowledge. It has thus come to represent a region where lawyers debaters and philosophers can all find some common around. In Presumption and the Practices of Tentative Cognition Nicholas Rescher endeavors to show that the process of presumption plays a role of virtually indispensable utility in matters of rational inquiry and communication. The origins of presumption may lie in law but its importance is reinforced by its service to the theory of information management and philosophy.
