Upon completing the study, Perelman considered its conclusion untenable since value judgments form an integral part of all practical reasoning and decision-making, and to claim that these judgments lack any logical basis was to deny the rational foundations of philosophy, law, politics, and ethics. The New Rhetoric and its later developments have been foundational for argumentation theory in the last thirty years, and Perelman's work has influenced studies ranging from justice and reason to social psychology and political geography. The German philosopher Hans-Georg Gadamer cites Perelman's work on rhetoric as an influence on the hermeneutical philosophy he presented in Truth and Method, his masterpiece.[14] ./cache/en-wikipedia-org-7573.html ./txt/en-wikipedia-org-7573.txt
