"Nietzsche and Adorno’s radicalized critiques of modernity strives to lay bare the ideologies underlying human existence. They reject dogmas and absolutes and question moral values and categories and explanations, such as identity, origin, telos, substance, and appearance, as institutionalized narratives created to establish a ration order of things. Constructed to legitimize claims to power these concepts perpetuate notions of continuity, progress, and absolute truth. By acknowledging the limits of thought and the potential for error and both the repressive-regressive and progressive-emancipatory dimensions of values and norms, Nietzsche’s perspectivism turns, like Adorno’s negative-dialectical thought, to the undogmatic reevaluation of all values. Both contend that the traditional concept of rationality is bankrupt and has been reduced to forms of instrumental reason: a reason utilized for the purposes of self-preservation and the legitimation of claims to power. Modern rationality is dominated by logic and numbers, while the reductionist approaches of positivism operate in the name of science and technology. Nietzsche argues against theoretical men and Socratism, Adorno against commodification and instrumental reason."
