This book focuses on a central notion in Theodor. W. Adorno’s philosophy: the nonidentical. The nonidentical is what our conceptual framework cannot grasp and must therefore silence, the unexpressed other of our rational engagement with the world. This study presents the nonidentical as the multidimensional centerpiece of Adorno’s reflections on subjectivity, truth, suffering, history, art, morality and politics, revealing the intimate relationship between how and what we think. Adorno’s work, written in the shadow of Auschwitz, is a quest for a different way of thinking, one that would give the nonidentical a voice – as the somatic in reasoning, the ephemeral in truth, the aesthetic in cognition, the other in society. Adorno’s philosophy of the nonidentical reveals itself not only as a powerful hermeneutics of the past, but also as an important tool for the understanding of modern phenomena such as xenophobia, populism, political polarization, identity politics, and systemic racism.

In Adorno's Theory of Philosophical and Aesthetic Truth, Owen Hulatt undertakes an original reading of Theodor W. Adorno's epistemology and its material underpinnings, deepening our understanding of his theories of truth, art, and the nonidentical. Hulatt's novel interpretation casts Adorno's theory of philosophical and aesthetic truth as substantially unified, supporting the thinker's claim that both philosophy and art are capable of being true. For Adorno, truth is produced when rhetorical "texture" combines with cognitive "performance," leading to the breakdown of concepts that mediate the experience of the consciousness. Both philosophy and art manifest these features, although philosophy enacts these conceptual issues directly, while art does so obliquely. Hulatt builds a robust argument for Adorno's claim that concepts ineluctably misconstrue their objects. He also puts the still influential thinker into conversation with Hegel, Husserl, Frazer, Sohn-Rethel, Benjamin, Strawson, Dahlhaus, Habermas, and Caillois, among many others.

Adorno continues to have an impact on disciplines as diverse as philosophy, sociology, psychology, cultural studies, musicology and literary theory. An uncompromising critic, even as Adorno contests many of the premises of the philosophical tradition, he also reinvigorates that tradition in his concerted attempt to stem or to reverse potentially catastrophic tendencies in the West. This book serves as a guide through the intricate labyrinth of Adorno's work. Expert contributors make Adorno accessible to a new generation of readers without simplifying his thought. They provide readers with the key concepts needed to decipher Adorno's often daunting books and essays.

Decades before the environmental movement emerged in the 1960s, Adorno condemned our destructive and self-destructive relationship to the natural world, warning of the catastrophe that may result if we continue to treat nature as an object that exists exclusively for our own benefit. "Adorno on Nature" presents the first detailed examination of the pivotal role of the idea of natural history in Adorno's work. A comparison of Adorno's concerns with those of key ecological theorists - social ecologist Murray Bookchin, ecofeminist Carolyn Merchant, and deep ecologist Arne Naess - reveals how Adorno speaks directly to many of today's most pressing environmental issues. Ending with a discussion of the philosophical conundrum of unity in diversity, "Adorno on Nature" also explores how social solidarity can be promoted as a necessary means of confronting environmental problems.

Identity has become a central feature of national conversations: identity politics and identity crises are the order of the day. We celebrate identity when it comes to personal freedom and group membership, and we fear the power of identity when it comes to discrimination, bias, and hate crimes. Drawing on Isaiah Berlin's famous distinction between positive and negative liberty, Theodor Adorno and the Century of Negative Identity argues for the necessity of acknowledging a dialectic within the identity concept. Exploring the intellectual history of identity as a social idea, Eric Oberle shows the philosophical importance of identity's origins in American exile from Hitler's fascism. Positive identity was first proposed by Frankfurt School member Erich Fromm, while negative identity was almost immediately put forth as a counter-concept by Fromm's colleague, Theodor Adorno. Oberle explains why, in the context of the racism, authoritarianism, and the hard-right agitation of the 1940s, the invention of a positive concept of identity required a theory of negative identity. This history in turn reveals how autonomy and objectivity can be recovered within a modern identity structured by domination, alterity, ontologized conflict, and victim blaming.

Adorno’s lectures on ontology and dialectics from 1960–61 comprise his most sustained and systematic analysis of Heidegger’s philosophy. They also represent a continuation of a project that he shared with Walter Benjamin – ‘to demolish Heidegger’. Following the publication of the latter’s magnum opus Being and Time, and long before his notorious endorsement of Nazism at Freiburg University, both Adorno and Benjamin had already rejected Heidegger’s fundamental ontology. After his return to Germany from his exile in the United States, Adorno became Heidegger’s principal intellectual adversary, engaging more intensively with his work than with that of any other contemporary philosopher. Adorno regarded Heidegger as an extremely limited thinker and for that reason all the more dangerous. In these lectures, he highlights Heidegger’s increasing fixation with the concept of ontology to show that the doctrine of being can only truly be understood through a process of dialectical thinking. Rather than exploiting overt political denunciation, Adorno deftly highlights the connections between Heidegger’s philosophy and his political views and, in doing so, offers an alternative plea for enlightenment and rationality. These seminal lectures, in which Adorno dissects the thought of one of the most influential twentieth-century philosophers, will appeal to students and scholars in philosophy and critical theory and throughout the humanities and social sciences.

Nietzsche and Adorno on Philosophical Praxis, Language, and Reconciliation: Towards an Ethics of Thinking offers a philosophical notion of an “ethics of thinking,” a kind of thinking that is receptive to the non-identical character of the world of human and non-human objects. Paolo A. Bolaños experiments with the ideas of Friedrich Nietzsche and Theodor W. Adorno, who are presented as contemporary proponents of the Frühromantik tradition. Bolaños offers a reconstruction of the respective philosophies of language of Nietzsche and Adorno, as well as a rehearsal of their critique of metaphysics and identity thinking, in order to develop a notion of philosophical praxis that is grounded in the ethical dimension of thinking. Via Nietzsche and Adorno, Bolaños argues that thinking’s performative participation in uncertainty broadens the domain of reason, thereby also broadening our conceptual capacities and our receptivity to new possibilities of thinking. As an ethical praxis, thinking guards itself from the error of solidification, thereby opening philosophy to a reconciliatory, as opposed to domineering, reception of the world.
