Against Epistemic Frivolity: Karl Popper and the Restoration of Objectivity

Against Epistemic Frivolity: Karl Popper and the Restoration of Objectivity

— Christopher S. Carson, J.D., M.A. June 2025

The recent death of Bruno Latour, celebrated by the academic commentariat with a kind of reverent exuberance, offers an occasion for reflection: just not, perhaps, the kind Latour’s admirers intended. Lauded as a visionary thinker, a liberator from the “naive” realism of earlier science, Latour was hailed in tributes from leading journals and universities as the man who taught us that facts themselves are constructed, negotiated, contingent upon the networks of power and discourse that sustain them.

Such adulation is itself symptomatic of a deeper malaise. It reveals the extent to which the modern academy, intoxicated by its own cleverness, has embraced the very sophistry that Socrates once labored to expose. Latour’s denial of objective truth, his portrayal of scientific knowledge as little more than a social confection, may be adorned with the fashionable terminologies of “actor-network theory” and “science studies,” but its essence is ancient. It is the doctrine of Protagoras reborn in postmodern garb: unaided man is the measure of all things; truth is not discovered but manufactured; knowledge is not submission to reality but the exercise of rhetorical power.

Latour is not an isolated figure. He stands in a long lineage of intellectual deconstructionists — from Thomas Kuhn’s portrayal of scientific revolutions as paradigm shifts governed by community consensus, to Paul Feyerabend’s gleeful anarchism in Against Method, to Richard Rorty’s conversational relativism and Stanley Fish’s interpretive opportunism.

All of them, despite their pretensions to novelty, merely rehearse the ancient sophist’s creed: that truth is a fiction and persuasion, or posturing, is the highest art. Against this tide of epistemic frivolity stands the solitary figure of Karl Popper. Like Socrates before him, Popper refused to surrender to the cynicism of his age. He recognized the fallibility of human reason, but he also recognized its dignity. He understood that the very acknowledgment of our limitations is what ennobles the pursuit of truth, what demands of us the discipline of critical inquiry and the humility to submit our theories to falsification.

In the long and often confused history of human inquiry, Popper emerges with a peculiar austerity, as if he intuited from the outset that science, properly understood, was not a mere profession but a moral vocation. It was not enough to collect facts, not enough to construct theories, not enough even to innovate. For Popper, the integrity of the enterprise rested on a single, luminous principle: fallibility. All human knowledge, he insisted, is provisional. Every theory, no matter how august its pedigree or wide its acclaim, is but a hypothesis awaiting its refutation. The growth of knowledge proceeds not through the accumulation of confirmed truths, but through the ruthless culling of error. Science is an endless and asymptotic approach to truth, always incomplete, always open to criticism, always subject to falsification.

This conception stands in sharp contrast to the contemporary tendency to treat science as a repository of settled certitudes, the possession of an elite class of experts to be accepted by the laity without inquiry. Popper rejected this with the ferocity of a man who had lived through the political consequences of intellectual dogmatism in the totalitarian movements of the twentieth century. For him, truth was not the property of a caste or a class; it was an ideal, transcendent and universal, to which all men had access through the disciplined exercise of reason.

Thus Popperian science is not merely a method, though it is methodical; it is not merely a technique, though it is technical; it is a discipline, both intellectual and moral. It demands a particular posture from the individual: humility before the facts, openness to correction, and a willingness to see one’s most cherished theories discarded in the light of better evidence or sharper reasoning. The scientific attitude, for Popper, is a species of virtue. It cultivates the habits of mind necessary not only for intellectual inquiry but for the preservation of a free and open society.

The discipline of falsification stands at the heart of this project. A theory is not scientific unless it can, in principle, be proven false. A theory that can accommodate any and all evidence is not a triumph of ingenuity but a capitulation to vacuity. Science progresses by the boldness of its conjectures and the severity of its tests. Only those theories that survive rigorous and repeated attempts at refutation are tentatively admitted into the corpus of scientific knowledge, and even these are held lightly, always subject to future correction.

This relentless openness to criticism is what grants science its peculiar dignity. It is not the infallibility of its conclusions that sets science apart, but the fallibility of its methods, acknowledged and embraced. In a world increasingly given over to ideological certainty and performative expertise, Popper’s vision offers a tonic of intellectual humility and moral seriousness. He reminds us that to seek the truth is not to claim possession of it, but to submit oneself to its demands.

If Popper is the philosopher of scientific aspiration, Thomas Kuhn is the historian of scientific disillusionment. In The Structure of Scientific Revolutions, Kuhn argued that science does not progress by the steady accretion of knowledge but by revolutionary paradigm shifts, governed as much by sociological and psychological factors as by empirical ones. Within a paradigm, normal science proceeds as a kind of puzzle-solving activity. Scientists are not typically engaged in falsifying the paradigm itself, but in elaborating its implications. Anomalies are not immediately taken as refutations; they are explained away.

Only when anomalies accumulate to a critical mass does a crisis ensue, leading not to rational deliberation but to a revolutionary overthrow of the reigning framework. Kuhn compared the shift to a Gestalt switch, the sudden reorientation of perception — the duck becomes a rabbit. The two paradigms are incommensurable: they offer fundamentally different ways of seeing the world, and there is no neutral court of appeal that can adjudicate between them on purely rational grounds.

The implications are sobering. Scientific change, on Kuhn’s account, is not governed by reason alone but by community consensus, professional allegiances, and the dynamics of belief. Science is less a rational enterprise than a social one.

It’s important to realize that Kuhn did not see himself as a normative proponent of this dark architecture of scientific progress, merely its chronicler. But in his Structure book, he certainly gave no hope to his reader in a more idealistic future. We might be forgiven for assuming that, in his view, the entire scientific enterprise of humanity is a hopeless fraud, and not worthy of an intelligent man’s scrutiny or time.

Kuhn’s co-religionist, Paul Feyerabend, radicalized this picture. In Against Method, he argued that there is no scientific method, no set of rules governing progress. The only principle that does not inhibit discovery, he famously said, is anything goes. Feyerabend transformed fallibility from a discipline into a license for anarchy. Science, stripped of method, becomes indistinguishable from myth, politics, or art.

This pattern repeats elsewhere. Jean-Paul Sartre disavowed moral absolutes, leaving man adrift in a universe without ethical lodestar, although strangely, he felt it necessary to enroll in the Communist Party, which most certainly had opinions about how mankind ought to live, how we ought to live under the particularly heavy hand of Communist government.

Richard Rorty, the hip philosopher par excellence, even denied that truth corresponds to reality, reducing knowledge itself to the contingencies of conversation. The celebrated Duke University literature professor, Stanley Fish, declared that meaning is not in the text but in the reader’s interpretive community. Interestingly, Professor Fish also called himself a “Marxist,” the less-offensive, more academically neutral term for Communist. But if meaning does not reside in any text, does this not mean that the Communist Manifesto and the Teutonically-turgid Das Kapital are un-tethered from any intrinsic meaning? If so, why would Fish be enamored of “Marxism?”

All of them, in their way, dance among the ruins of seriousness, treating the fallibility of human reason not as a call to humility but as an excuse for frivolity. They are the heirs not of Socrates but of the sophists, those purveyors of cleverness without wisdom. The recent canonization of Bruno Latour by the academic and media establishments exemplifies this phenomenon.

Latour’s denial of scientific objectivity, his insistence that facts are negotiated artifacts rather than discovered realities, has been celebrated not as a provocation to be answered but as a liberation to be applauded. His death was met not with critical reflection but with hagiography, a symptom of the modern academy’s surrender to sophistry.

The sophists of antiquity proclaimed that man is the measure of all things, denying the existence of objective standards and reducing all claims to matters of custom and power. Socrates spent his life resisting them, armed with nothing but reason and the conviction that truth, though elusive, was real and worth pursuing. Karl Popper stands in that same tradition. Like Socrates, he begins with the acknowledgment of human fallibility, but he refuses to capitulate to skepticism or relativism. For Popper, fallibility is not a pretext for despair but a call to discipline. It is the very condition that makes the pursuit of truth not only possible but noble.

Popper’s critical rationalism is the enduring antidote to the disease that has infected modern thought. It reminds us that while human reason is frail, it is not futile; that while truth may be elusive, it is not illusory; that while certainty may be denied us, knowledge is still attainable through the hard labor of conjecture and refutation. In an age where many are content to dance among the ruins of meaning, Popper calls us to rebuild. He asks us to take seriously the task of inquiry, to submit our ideas to the tribunal of evidence and reason, to cherish the ideal of truth even as we confess our fallibility.

The world has always had its sophists. What it needs, now more than ever, are its Socratic heirs: those who, like Popper, refuse to surrender to the cynicism of the age, who recognize that the love of truth is not a passing fashion but a permanent vocation. In the end, it is not the deconstructors and the relativists who are novel. They are ancient, and their errors are ancient. It is the critical rationalist, the seeker after truth, the man who aspires against the gravity of human weakness: he is the true modern, the true progressive, the true heir of the Socratic legacy.

And if a man’s reach must exceed his grasp, it is because heaven, not the abyss, is his proper home.
