Adorno's Gamble offers a startling reinterpretation of the evolution of Adorno's thought, usually seen as a mix of critical Marxism, Freudian psychoanalysis, aesthetic modernism, and Jewish tradition. Mikko Immanen argues for another, previously unacknowledged source of his thinking on instrumental reason, dialectic of enlightenment, and frailty of democracy: the intellectual underpinnings of Germany's "conservative revolutionary" movement of the 1920s. In a dramatic reappraisal of the leading light of the Frankfurt School, Immanen follows Adorno's path of philosophical development from the late Weimar era through years in exile to the postwar period, establishing his debt to thinkers of radical conservative bent. In particular, he focuses on Adorno's enduring, and daring, effort to harness two of the most infamous works from this tradition—Oswald Spengler's Decline of the West and Ludwig Klages's Spirit as Adversary of the Soul—and to repurpose their reactionary teachings for emancipatory ends.
