"Dialectic of Enlightenment" is undoubtedly the most influential publication of the Frankfurt School of Critical Theory. Written during the Second World War and circulated privately, it appeared in a printed edition in Amsterdam in 1947. "What we had set out to do," the authors write in the Preface, "was nothing less than to explain why humanity, instead of entering a truly human state, is sinking into a new kind of barbarism." Yet the work goes far beyond a mere critique of contemporary events. Historically remote developments, indeed, the birth of Western history and of subjectivity itself out of the struggle against natural forces, as represented in myths, are connected in a wide arch to the most threatening experiences of the present. The book consists in five chapters, at first glance unconnected, together with a number of shorter notes. The various analyses concern such phenomena as the detachment of science from practical life, formalized morality, the manipulative nature of entertainment culture, and a paranoid behavioral structure, expressed in aggressive anti-Semitism, that marks the limits of enlightenment. The authors perceive a common element in these phenomena, the tendency toward self-destruction of the guiding criteria inherent in enlightenment thought from the beginning. Using historical analyses to elucidate the present, they show, against the background of a prehistory of subjectivity, why the National Socialist terror was not an aberration of modern history but was rooted deeply in the fundamental characteristics of Western civilization. Adorno and Horkheimer see the self-destruction of Western reason as grounded in a historical and fateful dialectic between the domination of external nature and society. They trace enlightenment, which split these spheres apart, back to its mythical roots. Enlightenment and myth, therefore, are not irreconcilable opposites, but dialectically mediated qualities of both real and intellectual life. "Myth is already enlightenment, and enlightenment reverts to mythology." This paradox is the fundamental thesis of the book. This new translation, based on the text in the complete edition of the works of Max Horkheimer, contains textual variants, commentary upon them, and an editorial discussion of the position of this work in the development of Critical Theory.

One of the most salient features of our culture is that there is so much bullshit. Everyone knows this. Each of us contributes his share. But we tend to take the situation for granted. Most people are rather confident of their ability to recognize bullshit and to avoid being taken in by it. So the phenomenon has not aroused much deliberate concern. We have no clear understanding of what bullshit is, why there is so much of it, or what functions it serves. And we lack a conscientiously developed appreciation of what it means to us. In other words, as Harry Frankfurt writes, 'we have no theory'. Frankfurt, one of the world's most influential moral philosophers, attempts to build such a theory here. With his characteristic combination of philosophical acuity, psychological insight, and wry humor, Frankfurt proceeds by exploring how bullshit and the related concept of humbug are distinct from lying. He argues that bullshitters misrepresent themselves to their audience not as liars do, that is, by deliberately making false claims about what is true. In fact, bullshit need not be untrue at all. Rather, bullshitters seek to convey a certain impression of themselves without being concerned about whether anything at all is true. They quietly change the rules governing their end of the conversation so that claims about truth and falsity are irrelevant. Frankfurt concludes that although bullshit can take many innocent forms, excessive indulgence in it can eventually undermine the practitioner's capacity to tell the truth in a way that lying does not. Liars at least acknowledge that it matters what is true. By virtue of this, Frankfurt writes, bullshit is a greater enemy of the truth than lies are.
