Kant's "Critique of Pure Reason" establishes critique as a philosophical method — the examination of the conditions and limits of knowledge — and this critical spirit runs through poetry that examines its own conditions of possibility, from the Romantics' self-reflexive odes to contemporary metapoetry; Adorno's "negative dialectics" and his aesthetic theory extend the critical tradition into culture, arguing that authentic art is itself a form of critique — the artwork that does not affirm the existing order but challenges its categories; A poet writing in response to political events might make critique the explicit purpose of the poem — not merely lamenting injustice but analyzing its structural causes and the ideological mechanisms that make it seem natural or inevitable; Blake's prophetic books are sustained philosophical critiques of Enlightenment rationalism, industrial capitalism, and organized religion, using the visionary poem as an instrument of critical illumination; Feminist and postcolonial poetry enacts critique as a philosophical practice — the examination of the patriarchal, racist, or imperial assumptions embedded in inherited traditions of representation and evaluation; Brecht's "Verfremdungseffekt" (alienation effect) is a technique of poetic and theatrical critique — by making the familiar strange, the artwork prevents emotional identification and produces the critical distance necessary for genuine understanding of social conditions
