While Marcuse dreamed of utopia in America, Adorno despaired in Europe. ‘No universal history leads from savagery to humanitarianism, but there is one that leads from the slingshot to the megaton bomb’,‘ he wrote in Negative Dialectics, the book he published in 1966 under the long shadow of Auschwitz and the threat of nuclear Armageddon. The Holocaust imposed what he called a ‘new categorical imperative’ that human beings arrange their thought and action so that ‘Auschwitz would not repeat itself, [that] nothing similar would happen’. In Adorno’s corner of Frankfurt, there was no future in Marcuse’s Californian dreaming. Negative Dialectics is an untimely meditation anti-systemic, anti-utopian and devoid of hope. ‘There can be few works of philosophy that give such an overpowering sense of sterility as Negative Dialectics’, wrote Kolakowski in Main Currents of Marxism. Marcuse may have thought that utopia could be realised in this world and soon, but Adorno’s implicit counter suggestion in Negative Dialectics was that it could only be realised in art, and there by definition only imaginatively.
‘Negative dialectics flouts tradition’, he wrote in the book’s preface. ‘As early as Plato, dialectics meant to achieve something positive by means of negation . . . This book seeks to free dialectics from such affirmative traits without reducing its determinacy.’ Before Plato, Heraclitus had proposed that the world is constantly in flux. The dialectical imagination takes this thought and tries to impose order on the change: for dialecticians, and Adorno was a lifelong member of that dialectical club, the question is, if the world essentially involves change not stasis, then where is that change heading?
The suggestion from Plato onwards was that change, and in particular historical change, has a goal or telos. Hegel’s idea was that history unfolds through dialectical process. The paradoxical German term ‘aufheben‘, which means three different and contradictory things to preserve, to elevate and to cancel and which, in its philosophical usage. is usually translated as ‘sublate’, is important here. The translator and philosopher Walter Kaufmann wrote: ‘Hegel may be said to visualise how something is picked up in order that it may no longer be there just the way it was, although, it is not cancelled altogether but lifted up to be kept on a different level." Crucially for Hegel, nothing is discarded in this process everything is taken up from one historical age to the next. For him, history is the unfolding of human freedom towards the Absolute and, what is the same thing, the expression of the Weltgeist, or world spirit. For Hegel ‘everything that is real is rational’, by which he means that everything has its place in the unfolding dialectical process. The result is that there is an ‘identity of identity and non-identity’. History, thus conceived, is like a cosmically large recycling project in which nothing is allowed to become mere landfill. For Hegel, consequently, the whole is the true. For Adorno, in a typically perverse aphorism, the opposite is the case: ‘The whole is the false.’
Throughout his writings Adorno is suspicious of those philosophies that offer harmonious reconciliations. He was doubtful, as Martin )ay put it, of the young Lukacs’s vision of epic wholeness in ancient Greece, of Heidegger’s notion of a fulfilled being now tragically forgotten, and of Walter Benjamin’s faith in a prelapsarian oneness of name and thing." But in Negative Dialectics, he was chiefly concerned, not with deconstructing such regressive fantasies, but with opposing the idea that dialectical historical processes had to have a goal. In particular, he rejected the idea that the narrative of history was destined to conclude with a happy ending. Thus, in opposition to Hegel's ‘identity of identity and non-identity’, Adorno proposed the even more battling notion of ‘the non-identity of identity and non-identity’. In making this suggestion, Adorno was asserting that the object does not go into its concept without remainder. And yet an object has to be subsumed without remainder if identity thinking is to make sense. If the object does not go into its concept without remainder then, because all thinking is conceptual, all concepts misrepresent their objects and all thinking involves an act of brutality to its object. such. at least, was Adorno‘s inference.
Effectively, Adorno was deploying Marx’s account of the exchange principle retrospectively to put holes in Hegelian identity philosophy: in achieving identity, Adorno suggested, Hegelian philosophy asserts the equivalence of what is not equivalent. Instead of such brutal identity thinking, Adorno tentatively proposed a different approach to knowledge, what has become known as a constellational theory, borrowing the term ‘constellation’ from Walter Benjamin’s The Origin of German Tragic Drama. Constellational thinking rejects the identity thinking that understands an object by subsuming it under a concept. To understand an object, for Adorno, was not to subsume it under concept but to set it in dialectical historical relationship with a constellation of other objects. In this sense, there is a strong parallel between constellational thinking and Benjamin’s notion of the dialectical image. This use of the term constellation bears affinities with the devices of modernist art and literature that appealed to Benjamin such as cinematic montage, cubist collage, Baudelaire’s correspondances or Joyce’s epiphanies.
In particular, Benjamin’s constellations were akin to Proust’s notion of involuntary memory. When he tastes a madeleine, the narrator of Proust’s A la recherche du temps perdu involuntarily brings his whole childhood to life. These sudden flashes of insight were what Adorno hoped for in his constellational theory of knowledge. Through such changing constellations and such evanescent flashes, the truth about an object would emerge to the sympathetic observer. Adorno unveiled this approach to cognition in his inaugural lecture at the Institute for Social Research in Frankfurt in 1931 to be greeted with incomprehension by his listeners. In Negative Dialectics, he tried to expound a new version, using an analogy that made him sound like a combination of a safe-cracker labouring in a bank’s vault after working hours, a Buddhist virtuoso of mindfulness, and a quantum physicist aware that his investigation is going to change the nature of what he's investigating.
Insight if it is to beattained at all, was to be reached by adepts who had transcended identity thinking, and then on in flashes... constellations.... always changing, flickering in and out of the beholders' grasp.
When Gershom Scholem read Negative Dialectics, he wondered if critical theory now amounted to Marx’s analysis of capitalism without the class struggle. If so, that could equally be said of Marcuse’s One-Dimensional Man. But while Marcuse spent the 1960s looking for a revolutionary subject to replace the proletariat, Adorno’s philosophy was a reversal of Marxism: it could never help change the world, but only interpret it more profoundly. If it had a role, it was to reduce the systems of other philosophers to rubble and thus help cure the faithful of their delusions.
In his 1964 book Jargon of Authenticity, for instance, Adorno attacked the post-war tendency in German philosophy to find delusive succour in subjective inwardness. That kind of existential turn in philosophy which he had critiqued in his pre-war works on Husserl and Kierkegaard he found especially intolerable in the writings of Heidegger, Martin Buber and Karl Jaspers. He took their works to be self-mystificatory. Each in their own way devised elitist philosophies with abstruse terms in order to avoid confronting social realities, basking in the purported glow of such words as angst and leap, and thereby distracting themselves from the darkness of the times. What Wittgenstein said of his mission was also true of Adorno’s in Jargon of Authenticity: ‘This sort of thing has got to be stopped. Bad philosophers are like slum landlords. It’s my job to put them out of business.’
In 1961, Adorno met Karl Popper in Tabingen at the German Sociological Association. Both were principal speakers at a symposium to debate the methodology appropriate to social science research. It should have been a bruising encounter, a prize fight between two representatives of hostile philosophical positions or a Cold War era confrontation between the representatives of the rival ideologies of liberal democracy and Marxism.
In the blue corner was the Viennese-born Popper, professor of logic and scientific method at the University of London, of whom his British disciple Bryan Magee once said: ‘He puts me in mind of a blowtorch” Popper was the defender of the Open Society against various forms of totalitarianism, champion of scientific method, acerbic excoriator of what he called pseudo-sciences such as psychoanalysis, and insistent that the dialectical thinking in which the Frankfurt School specialised was not only false but dangerous.
In the red corner was Adorno, a man whom even his dedicated and sympathetic follower Martin lay found painfully capable of the ‘withering rant'. Adorno doubted that the liberal, putatively open society that Popper extolled against totalitarianism was so very different from the latter. He, like other Frankfurt School critical theorists, had been impressed by Freudian psychoanalysis. Most significant, as the two men squared up, was that Adorno was sceptical about the pretensions of scientific method to be an objective means of establishing truth. ”The idea of scientific truth cannot be split off from that of a true society'. Adorno wrote.” The corollary being that, given that we do not live in the latter, the former is beyond us. This conception of scientific truth was to have ramifications, not just for the natural sciences. but for the topic of the symposium- namely how sociology should work.
For the Frankfurt School. the sciences, be they natural or social. had become tools used by capitalism’s oppressors to keep the true society from coming into being. Philosophy too, by abandoning a critical perspective on social reality, became a tool of oppression rather than liberation.
The task facing the Frankfurt School was to free oppressed humanity from a mindset that ensnared individuals in the pursuit of happiness rather than questioning why the sought such an end. Because there was no critical reflection on the irrationality of such ends, Horkheimer thought that the project of Enlightenment became self-defeating. Enlightenment was supposed to involve the use of reason to free humanity from myth and superstition. Instead it replaced one myth with another. "The wholly enlightened earth is radiant with triumphant calamity", they wrote.
Enlightenment creates a world the better to fit its scientific picture of it. But that world is a distortion. We have a false sense of connectedness with the world that gives us a limited sense of how the world can be.
That said, Popper’s views about science were as challenging to scientific orthodoxy as to the Frankfurt School. His 1934 book The Logic of Scientific Discovery followed the Scottish Enlightenment philosopher David Hume who had pointed out that there is a contradiction in the notion that all knowledge is derived from experience and that general statements, including scientific laws, are verifiable by reference to experience. This notion was the foundational commitment of empiricism and indeed of positivism. And yet, Hume argued, no scientific hypothesis could be finally confirmed and so no scientific law could be definitively true. For example, if all the swans we have seen are white. that doesn’t mean the proposition ‘All swans are white’ is true. This was the problem of induction, and yet, Hume suggested, we cannot help but use inductive reasoning even if we cannot justify its results as knowledge.
Hume’s scepticism about the rational basis of induction was inspiring to Popper because it challenged the prevailing view that. only what can be proved by reason and experience can be accepted. This perspective on how science worked, called justificationism, and forming the rhetorical basis for much of science’s endeavour to understand the world (the better, as the Frankfurt School would argue, to dominate it), was opposed by Popper. Like the Frankfurt School, if for utterly different reasons, he sought to clip the wings of science, to undermine its pretensions. For him, the progress of science did not so much expand the frontiers of human knowledge as reveal the vast empire of our ignorance. As he said at Tubingen, ‘Indeed, it is precisely the staggering progress of the natural sciences . . . which constantly opens our eyes anew to our ignorance, even in the field of the natural sciences themselves.’
For Popper, every test of a scientific hypothesis involves an attempt to refute or to falsify it, and one genuine counter-example will falsify the whole theory. He argued that the same scientific method of testing hypotheses did not apply in the case of psychoanalysis or Marxism Rather, because there was no evidence that could count as false in either theory, he thought, nothing could refute them. Both psychoanalysis and Marxism were for Popper akin to astrology: by refusing to countenance any counter-examples they made themselves unfalsifiable and therefore superficial.
To be sure, Popper’s account of the logic of scientific discovery is hardly uncontroversial and it was questioned by later philosophers of science, in particular the American Thomas Kuhn, who pointed out that scientists are more loath to give up cherished hypotheses than Popper suggested. Instead of taking one counter-example to spell doom for a hypothesis, scientists tend to shore it up with auxiliary hypotheses. This so-called ‘conventionalist stratagem’ makes a lot of sense, not least if you have spent a lot of time, intellectual effort and money testing a beloved hypothesis. Scientists, and this is something readily forgotten in the philosophy of science, are human too.
Indeed, Kuhn argued in his 1962 book The Structure of Scientific Revolutions that science involves competing paradigms, each of which consists of a core theory and auxiliary hypotheses.” The latter change but the former remains constant until that upsetting moment when it proves impossible to support the core theory through modified hypotheses. Then something unusual happens, which Kuhn called a paradigm shift, wherein the core theory is abandoned or radicaly changed- often when the old guard retire or die.
Popper’s perspective on how science worked is important because his 1961 meeting with Adorno was heralded as the start of the Positivmusstreit or Positivism Dispute that rumbled on until the end of the decade at a series of conferences in German universities. The name of the dispute might suggest a clash between the Frankfurt School and the defenders of the hubristic scientific project that arose during the Enlightenment, premised on submitting the world to human understanding and control, but the truth is more complicated. In fact, the Positivism Dispute is really a misnomer. Popper, for all that he had written for the Vienna Circle in the 1930s, was no positivist, or at least refused the description. Indeed, Otto Neurath had called Popper the official opposition to the Vienna School. Popper’s The Logic of Scientific Discovery, republished in an updated English language version only two years before the Tubingen symposium, included an eviscerating attack on the very basis of logical positivism, namely the verification principle, which asserts that a proposition is only cognitively meaningful if it can be definitively and conclusively determined to be either true or false, that is, either verifiable or falsifiable. It was a principle that applied a blowtorch to vast tracts of human discourse: if the verification principle held, then the judgements of ethics and aesthetics were meaningless, perhaps most charitably construed as more or less grunts of approval or disapprobation. And any talk of religion was similarly devoid of sense.
Popper would have none of this. He applied his own blowtorch to the principle, arguing that instead of verificationism what was needed was falsificationism. The latter meant, as we have seen, that hypotheses can be accepted as probable but never utterly confirmed.
Human knowledge. he argued. is never conclusive but only conjectural, hypothetical. aspiring to certainty perhaps but achieving only probability. Human knowledge in Popper’s perspective was like the British Empire or the Third Reich it may have seemed to its most blinkered supporters that its borders were conclusively established. that once territory was captured it need never be surrendered, but the truth was that it was provisional and liable to change.
But if Popper was no positivist, that didn’t stop Adorno and his acolytes during the dispute from describing him and his supporters. including the German philosopher Hans Albert, as such. ‘It must be restated in advance here’, wrote Adorno in a footnote to his introduction to a book about the dispute published in German in 1969 after hostilities had ceased, ‘that Popper and Albert distance themselves from the specific position of logical positivism. The reason why they are nevertheless regarded as positivists should be evident from what follows. What was evident was that Adorno called Popper and Albert positivists because they disdained to do what the dialecticians of the Frankfurt School did, namely to question the authority of science.
Popper, for his part, described himself as a critical rationalist. which makes drawing up the battle lines in Tubingen a marvellously challenging business. Adorno, after all, described himself as a critical theorist. But what is the difference between a critical rationalist and a critical theorist? Horkheimer in his essay ‘Traditional and Critical Theory’ distinguished between the Savant who doesn’t realise that the economic (and thus currently capitalist) structure of society shapes scientific work, and the critical theorist who does. For the Frankfurt School, a self-styled critical rationalist like Popper was just as much a Savant in that sense as other self-declared positivists were. But how did Popper understand the term critical rationalist? He made his own distinction between critical rationalism and ‘uncritical or comprehensive rationalism’. The latter was really another term for positivism. at least as the latter pertained to philosophy and science. It maintained that information derived from sensory experience, interpreted through reason and logic, forms the exclusive source of all authoritative knowledge.
