Reading from the Wrong Curve: Free Speech, Pseudo-Invariance, and the Grammar of Liberal Rights

This paper argues that contemporary free speech discourse is structured by a category error. The source of the error lies upstream of speech itself: in the treatment of 'freedom' as a stable philosophical primitive when, in practice, it functions as a constitutively contested concept. Drawing on Gallie’s account of essentially contested concepts and the Language Insufficiency Hypothesis, the paper introduces the term pseudo-invariant to describe a Contestable whose presumed effectiveness has been institutionally stabilised to the point where its core commitments operate as though settled, not because they are, but because the cost of reopening them exceeds what the framework can absorb. 'Freedom', in the context of liberal speech theory, is the paradigm case. The paper argues that the speaker-centred hierarchy implicit in liberal speech theory, from Milton and Mill to contemporary First Amendment doctrine, is not the neutral expression of what freedom requires but one historically situated resolution of freedom’s underdetermination. This resolution is inherited through the grammar of the framework rather than argued for afresh, and is actively maintained through rhetorical convention, juridical architecture, and coalition politics. As speech becomes ambient, amplified, and infrastructural, the inherited grammar of rights becomes increasingly misfitted to its object. The relevant phenomenon is no longer discrete utterance but epistemic environment: a commons speakers collectively condition and listeners are compelled to inhabit. Bringing this diagnosis into contact with Butler, Fish, Wu, and Waldron, the paper argues that even sophisticated corrective responses tend to reproduce the same underlying structure. The result is not merely a difficult balancing problem between speaker and listener rights, but a deeper misdescription of the phenomenon being governed. The paper does not propose a replacement framework. Its aim is diagnostic: to recover the prior question obscured by liberal speech discourse, namely whether “freedom” is stable enough to bear the philosophical and juridical weight assigned to it.
