Abstract

This paper examines Andrei Sakharov's dissident protests against the Soviet regime as arguments to a non-cooperating interlocutor. Approaching the 1970s-1980s Soviet dissident public sphere as a Toulminian ‘field’ of argumentation, I infer a field-dependent function of Sakharov's argument from an analysis of its structure and implicit assessment criteria. Besides justification, the function of Sakharov’s argument is performative: he argues for political action by demonstrating a model of practical reasoning that raises private consciousness to the level of public agency. By exposing his own political rationality as a ‘live’ mode of proof for the speculative ‘truth’ of his conviction, Sakharov suggests a connection between theoretical thinking and action.
