Adorno insists that aesthetic autonomy is a historical achievement, not a natural property. The conception of art as having its own purpose — beauty, truth, the expression of human possibility — emerged in the modern period and is bound up with the same bourgeois society that also produced the culture industry. Art's autonomy is both a genuine emancipation (from religious function, aristocratic patronage, didactic purpose) and a social fact whose conditions are social and therefore fragile. It cannot simply be defended as an eternal value; it must be understood as a contested achievement.
Adorno's most fundamental claim about art is that it is simultaneously autonomous and fait social — a social fact. Art's autonomy is real: genuine works of art have their own internal logic, their own formal requirements, their own standards of success and failure that are not reducible to social utility. But this autonomy is itself socially produced and sustained; it exists in and through society rather than above it. Art's social content is not a message that can be extracted from its form but is sedimented in the form itself — in the tensions, contradictions, and unresolved problems that constitute the work's internal life.
The critical function of aesthetic autonomy becomes clearest in its confrontation with the culture industry. Where the culture industry produces products that serve social functions (entertainment, distraction, the reproduction of consumer desire), autonomous art refuses function — and in refusing it, creates a space in which something other than the administered world can appear. This refusal is not comfortable: authentic modern art is difficult, demanding, formally intransigent. Its difficulty is the form taken by its commitment to truth.
Aesthetic autonomy is the subject of the opening pages of Aesthetic Theory (1970) and runs as a thread through the entire book. Adorno's position is in direct dialogue with Kant's account of aesthetic purposiveness without purpose in the Critique of Judgment.
