The concept of contingency has become one of the most pervasive yet elusive ideas in contemporary thought. It is invoked across disciplines- from philosophy and sociology to political theory and natural science - as a way to describe the openness of the future, the fragility of social orders, and the fundamental instability of meaning. But as its usage has expanded, its meaning has grown increasingly diffuse. What was once a precise modal-logical term, denoting what is neither necessary nor impossible, has morphed into a catch-all for anything that resists fixed determination. This conceptual inflation risks rendering contingency meaningless, transforming it from a powerful analytical tool into a mere rhetorical flourish.
In my recent work, Kontingenz ohne Maß – Zur Unschärfe eines Schlüsselbegriffs der postmetaphysischen Philosophie - Ein Beitrag zur begrifflichen Rekonstruktion und Systematisierung, I explore how this term has evolved from its origins in ancient and medieval thought to its current status as a buzzword in post-metaphysical discourse. The essay argues that contingency’s ubiquity has led to a crisis of meaning, where the term is often used more as a stylistic device than as a rigorous conceptual framework. To reclaim its analytical power, we must trace its historical development, distinguish between its various forms, and establish clearer boundaries for its application.
A Short History of Contingency: From Aristotle to Modernity
The idea of contingency first emerged in ancient philosophy as a way to describe what could be otherwise. For Aristotle, contingency referred to propositions that were neither necessarily true nor necessarily false. If Socrates is sitting, he could also be standing; his sitting is contingent. This was not a vague notion of randomness but a precise modal category, distinct from both necessity and impossibility. The scholastics, particularly Thomas Aquinas, deepened this understanding by framing contingency in theological terms. In Aquinas’ thought, only God is necessary; everything else - all of creation - is contingent, dependent on divine will. This was not a claim about chaos but about the dependence of the world on a higher order. Contingency, in this sense, was a structured concept, a way of distinguishing between what must be and what merely is.
Yet even in its early formulations, contingency carried tensions. Duns Scotus introduced the idea of haecceitas - the "thisness" of individual things - which suggested that contingency was not just a matter of divine choice but an inherent feature of reality itself. William of Ockham radicalized this further, arguing that even the laws of nature were contingent, subject to God’s absolute power. By the time of Descartes, contingency had shifted from a metaphysical to an epistemological problem. What we cannot know with absolute certainty, Descartes argued, is contingent. The external world, unlike the cogito, was inherently uncertain - a realm of mere probability rather than necessity.
The modern turn in philosophy, particularly with Leibniz and Hume, further transformed the concept. Leibniz, in his theory of possible worlds, framed contingency as the result of divine wisdom selecting the "best of all possible worlds." Here, contingency was still bound by reason, not sheer randomness. Hume, however, dismantled the idea of necessary causal connections, arguing that what we call "cause and effect" is merely a habit of association. For Hume, contingency was not just a feature of our knowledge but of reality itself. The world was not governed by hidden necessities but by observable regularities - and those regularities could always be otherwise.
The Radicalization of Contingency in the 19th and 20th Centuries
The 19th and 20th centuries saw contingency transformed from a structured concept into a fundamental condition of existence. Nietzsche’s proclamation of the "death of God" eliminated all ultimate grounds, leaving the world as a realm of pure becoming, where values, truths, and even identities were fluid and contestable. Heidegger deepened this insight, arguing that Being itself is contingent. In Being and Time, he described human existence as "thrown" into a world without predetermined meaning. Later, in his Black Notebooks, he suggested that even the history of Being was contingent - a series of unpredictable "sendings" without a guiding principle.
Existentialists like Sartre and Camus took this further, framing contingency as the very condition of human freedom - and human anguish. If there is no predetermined essence, we are condemned to create our own meaning in a world that offers no guarantees. By the mid-20th century, contingency had become the defining feature of modernity: a world without fixed foundations, where everything - from moral values to political orders - could be otherwise.
The Post-Metaphysical Inflation of Contingency
The second half of the 20th century witnessed an explosion of contingency into a master concept, used to describe everything from language and identity to history and science. But this expansion came at a cost. The term lost its precision, becoming a rhetorical placeholder rather than a rigorous analytical tool.
Niklas Luhmann, for instance, treated contingency as a structural feature of social systems. In his systems theory, every observation, every decision, every communication could have been different. Social systems - law, politics, economics - operate by reducing contingency, but they can never eliminate it entirely. Luhmann’s approach was brilliant in its formal rigor, but it also flattened the concept. If everything in modern society is contingent - if every system operates by selecting from a range of possibilities - then contingency loses its critical edge. It becomes a tautology: a description of how systems work, rather than a tool for distinguishing between what is necessary and what is not.
Similarly, Jacques Derrida and Judith Butler used contingency to undermine fixed meanings and identities. For Derrida, language is a system of differances, where no term has a fixed meaning. Every signifier is contingent, dependent on an endless chain of other signifiers. Butler applied this to gender and identity, arguing that even the most seemingly natural categories are performatively constructed - and thus contingent. Yet this radicalization of contingency also led to a paradox: if everything is contingent, then the concept loses its power to distinguish. If there are no fixed points at all, how can we critique anything? If all meanings are fluid, what grounds do we have for preferring one interpretation over another?
In the hands of thinkers like Peter Sloterdijk, Giorgio Agamben, and Slavoj Žižek, contingency became less a concept than a stylistic device. Sloterdijk treated it as the default condition of human existence, a fact to be managed through "anthropotechnics." Agamben focused on the contingency of law, particularly in states of exception where legal norms are suspended. Žižek used contingency to describe the unpredictable eruptions of the Real - moments when the symbolic order breaks down. But in each case, contingency was deployed more as a provocative gesture than as a precise analytical tool. The result was a floating signifier, a word that could mean almost anything - and thus risked meaning nothing at all.
Quentin Meillassoux and the Hyper-Chaos of Absolute Contingency
No thinker has pushed the logic of contingency further than Quentin Meillassoux. In After Finitude, he argues that not just events, but the very laws of nature are contingent. His "principle of absolute contingency" states that there is no necessity - except the necessity that nothing is necessary. Meillassoux’s project begins with a critique of correlationism - the idea, dominant since Kant, that we can only know the world as it appears to us, not as it is in itself. Against this, Meillassoux insists that we can think the absolute: not as a fixed order, but as the absence of any fixed order.
His key claim is that even the laws of physics could be otherwise. There is no reason why gravity must follow an inverse square law, why the speed of light must be constant, or why quantum mechanics must obey the Schrödinger equation. These laws are contingent facts, not eternal truths. Yet this radicalization of contingency leads to a conceptual dead end. If everything is contingent, including the laws that govern contingency, then the term loses all traction. How can we distinguish between what is contingent and what is not, if contingency itself is absolute? Meillassoux’s vision of a "hyper-chaos" - a world where anything can happen at any time - risks becoming a new kind of dogmatism. If contingency is the only necessity, then we are left with a metaphysics of pure randomness, which is just as rigid as the determinism it seeks to overthrow.
A Typology of Contingency: Four Distinct Forms
To rescue contingency from this inflation, we need to distinguish between its different forms. My work proposes a typology that separates contingency into four distinct types: logical, empirical, epistemic, and technical.
Logical contingency, the original sense of the term, refers to what is possible but not necessary. A statement is contingent if it is neither necessarily true nor necessarily false.
Empirical contingency, by contrast, refers to real-world openness, where events are not predetermined but depend on a range of factors. Evolutionary biology offers a clear example: the evolution of life on Earth was shaped by contingent events that could have turned out differently.
Epistemic contingency is uncertainty due to limited knowledge. We cannot predict the exact outcome of a quantum measurement, not because it is random in itself, but because our knowledge is incomplete.
Technical contingency, finally, is contingency that is intentionally introduced into systems, such as computer simulations or algorithmic decision-making. Each of these forms operates differently and serves different purposes.
By distinguishing between them, we can avoid conflating different senses of contingency and use the concept more rigorously.
Contingency in the Natural Sciences: Is the World Really Open?
One of the most contentious questions is whether contingency is just an epistemological tool or a feature of reality itself. The natural sciences offer three key perspectives. In classical mechanics, the universe is deterministic: if we knew the position and momentum of every particle, we could predict the future with perfect accuracy. Contingency here is purely epistemic - a result of our limited knowledge. Chaos theory complicates this picture by showing that even deterministic systems can produce unpredictable outcomes due to sensitive dependence on initial conditions. But this is still epistemic contingency - the system is deterministic, even if we can’t predict it.
Quantum mechanics challenges this view. At the microscopic level, particles do not have definite properties until they are measured. The collapse of the wave function appears to be a genuinely random event. If quantum randomness is real, then contingency is built into the fabric of reality. Evolutionary biology offers another perspective: Stephen Jay Gould famously argued that if we "rewound the tape of life" and played it again, we would get a completely different outcome. Evolution is shaped by contingent events that cannot be predicted in advance.
The sciences show that contingency is not a single phenomenon but operates differently in different domains. A rigorous philosophy of contingency must engage with these distinctions rather than treating all forms of openness as the same.
The Political and Ethical Stakes of Contingency
Contingency is not just an abstract concept—it has real-world consequences. In political theory, liberalism embraces contingency as the basis of pluralism, while conservatism often resists it, seeking stable traditions as bulwarks against chaos. Radical politics sometimes fetishizes contingency, treating all structures as arbitrary and ripe for overthrow. The danger is that inflationary uses of contingency can lead to paralysis, nihilism, or authoritarianism.
In ethics, if the world is contingent, then moral values are not fixed—they are products of history, culture, and choice. This can be liberating, but it also raises questions: if nothing is necessary, what grounds do we have for our choices? Existentialism argues that we must create our own values in a contingent world. Pragmatism suggests that we should focus on what works rather than on absolute truths. Critical theory tries to balance contingency with normative commitments, such as justice and democracy.
What we need is an ethics that acknowledges openness without falling into arbitrariness. If things could be otherwise, we must take responsibility for shaping them. But we also need islands of necessity—shared norms, scientific laws, ethical commitments—to navigate the openness of existence.
Reclaiming Contingency: Toward a More Rigorous Concept
To use contingency responsibly, we must distinguish between its forms, avoid the trap of absolute contingency, and use it as a tool for critique rather than just description. Contingency is most powerful when it exposes postulated necessities—when it shows that what seems natural or inevitable is actually contingent and could be changed.
A world that is purely contingent is unbearable. We need structures, norms, and commitments to give meaning to our actions. But a world without contingency is equally problematic—it would be a world without freedom, without novelty, without the possibility of change. The challenge is to think contingency rigorously: to distinguish between its forms, to use it as a tool for critique, and to balance openness with commitment.
In my work, I argue that this is the only way to reclaim contingency from the inflation that threatens to render it meaningless. The alternative is not a return to dogmatism but a more disciplined and nuanced engagement with the openness of the world. Contingency is not the enemy of reason—it is its condition. A world without contingency would be a world without freedom. But a world where everything is contingent is a world without meaning. The task is to navigate this tension, to embrace contingency without succumbing to arbitrariness, and to use it as a call to thought rather than a license for indifference.
