... the critique of intellectuals which Brecht developed... around the notion of ‘Tuismus’ engages a model of the public intellectual in which the self-image of the artist and thinker as a socially and politically engaged person corresponded to the expectations of the public. Partisan without being bound to a party, independent of official institutions yet experienced in surviving within institutions, prepared to entertain risks and undertake unconventional experiments: this was how Brecht accommodated a world which he envisioned as changeable. His antagonistic worldview fed on crisis and found its most productive, creative impulse in the escalation of contradictions.
Brecht routinely referred to the members of the Frankfurt School, particularly Theodor Adorno, as "Tuis". The corresponding term "Tuism" describes the theory and practice of the Tui-intellectual.
