In a recent article, Fabian Freyenhagen argues that we should understand first-generation Frankfurt School critical theory (in particular, the work of Adorno and Horkheimer) as being defined by a kind of ‘linguistic turn’ analogous to one present in the later Wittgenstein. Here, I elaborate on this hypothesis – initially by calling it into question, by detailing Herbert Marcuse’s extensive criticisms of Wittgenstein (and other analytic philosophers of language) in One-Dimensional Man. While Marcuse is harshly critical of analytic ordinary language philosophy, he is much more sympathetic to a different sort of ordinary language philosophy, which he unpacks with reference to Karl Kraus. I show how, by getting Marcuse’s criticisms of Wittgenstein and other analytic philosophers, and lauding of Kraus, into view, we can better understand the first generation of the Frankfurt School as having practised a sort of ‘non-quietistic’ philosophical therapy (that may or may not have been the sort of thing that Wittgenstein himself had in mind).
