The Unacceptable : Definition And Treatment

How can we define what cannot be legitimately imposed on anyone? Given the structural gap between social acceptability (what becomes sayable and debatable) and normative justifiability (what can be legitimately imposed), this work proposes a formal criterion of the unacceptable. After demonstrating how normalization mechanisms (habitus, cognitive closure, material constraints) render socially acceptable what may remain normatively problematic, we examine major normative theories' attempts (contractualism, capabilities, republicanism) to isolate the limits of legitimate imposition. Observing their structural failure, we prove that a norm is unacceptable when it can only be imposed at the cost of an arbitrary power asymmetry, that is, an asymmetry that circularly presupposes the authority it should establish, or that irreversibly captures future normative space. From this formal definition, we derive a normative transition principle organized around three axes (exit obligation, comparative minimization, anti-renaturalization public recognition), enabling treatment of residual unacceptability without normalizing it. This framework shifts the political question: no longer "what do people want?", but "what cannot be imposed on anyone?"
