A civilisation does not need to burn its books in order to forget what they mean.

It can preserve the books. It can maintain the temples, repeat the rituals, celebrate the festivals, and tell the same stories generation after generation. Outwardly, everything appears continuous.

Yet something essential can still disappear.

The words remain, but the relationships between them change. Practices survive while the assumptions that once made them intelligible gradually fade. Symbols are preserved, but the conceptual world that gave those symbols meaning begins to recede from view.

Eventually, a civilisation may continue speaking much of the same cultural language while losing familiarity with its underlying grammar.

This possibility first occurred to me while reflecting on Hindu traditions.

Words such as dharma, karma, yoga, avatāra, moksha, and tantra have survived remarkably well. Some have travelled far beyond India, appearing in political speeches, self-help books, popular culture, and everyday conversation. Their vocabulary remains astonishingly resilient.

But words often survive more easily than the conceptual worlds that once surrounded them.

Consider the word avatar.

Today an avatar is usually understood as a digital representation of oneself – a profile image, a gaming character, a social media persona, or a virtual identity. Few words have travelled more successfully across cultures.

In classical Hindu thought, however, an avatāra is not simply a representation. It is a descent of the divine into the world, a manifestation associated most famously with Vishnu’s interventions during periods of cosmic disorder. The concept belongs to a much larger framework involving time, dharma, creation, destruction, and the continual restoration of cosmic balance.

The word survived. Much of the grammar did not.

Perhaps this is how civilisations forget – not by losing their vocabulary, but by gradually forgetting the relationships that once made that vocabulary meaningful.

History often remembers change through visible events: revolutions, wars, reforms, and the rise and fall of empires. Yet some of the most consequential changes occur differently. They become so thoroughly absorbed into ordinary life that later generations no longer recognise them as changes at all.

Historical change often achieves its greatest success by becoming invisible.

What Is a Philosophical Grammar?

By philosophical grammar, I do not mean a formal doctrine or a list of official beliefs.

Grammar operates largely beneath conscious awareness. A fluent speaker rarely pauses before each sentence to consider the rules of syntax. Those rules have become part of the structure through which meaning itself is produced.

Civilisations may possess something similar.

Every civilisation inherits a network of assumptions that quietly shapes how its members understand the world. These assumptions determine not merely what answers seem persuasive but what kinds of questions appear worth asking in the first place.

What is a person?

What constitutes a good life?

What is desire?

What obligations do we owe one another?

How should the body relate to the sacred?

What is freedom?

Different civilisations do not merely answer these questions differently.

Sometimes they organise the questions themselves in fundamentally different ways. That distinction matters.

When one philosophical tradition is interpreted entirely through the conceptual categories of another, translation becomes more than translation. Familiar words remain, but the relationships between those words are rearranged.

Something is gained.

Something is inevitably lost.

When Dharma Becomes a Rule

Consider the Sanskrit word dharma.

It is commonly translated as duty, morality, law, religion, righteousness, or ethical obligation. Each translation captures something important.

None captures the whole.

The difficulty is not merely lexical. It is philosophical.

Dharma belongs to a framework in which ethical life has often been understood relationally rather than universally. What is appropriate depends not only upon abstract principle but also upon circumstance, responsibility, stage of life, and social role.

A householder and a renunciant, for example, are not expected to pursue identical forms of virtue.

The renunciant seeks detachment from daily responsibilities, possessions, family obligations, and sensual attachment. The householder, by contrast, fulfils obligations precisely through family life, productive work, social participation, and intimate relationships.

The same civilisation can therefore honour both paths without experiencing them as contradictions demanding resolution. This does not imply moral relativism.

It suggests something subtler: ethical life may consist not in applying a single universal rule to every situation but in balancing different responsibilities within different contexts.

Translate dharma simply as “moral law,” and something almost invisible occurs.

The vocabulary survives. The grammar shifts.

Something similar has happened to karma. In popular culture, karma is often reduced to a simple moral equation: “what goes around comes around.” The idea is recognizable, but it captures only part of a much larger philosophical framework. Classical discussions of karma concern not merely moral consequence but the relationship between action, intention, causation, rebirth, and ultimately liberation. Karma is less a cosmic system of instant justice than an account of how actions participate in shaping the moral and existential conditions of life. Once again, the word survives. Much of the grammar recedes from view.

A Civilisation Comfortable With Contradiction

Modern readers often approach religions with an expectation of consistency.

What does this religion believe?

Is desire good or bad?

Is the body sacred or dangerous?

Is renunciation superior to worldly life?

Which answer represents the authentic tradition?

These questions assume that a mature philosophical system ought to resolve apparent contradictions into a single coherent doctrine. Yet many traditions, Hinduism among them, evolved less like systematic philosophies and more like long conversations extending across centuries.

Within Hindu traditions, ascetics renounce sexuality while householders marry and raise families. Philosophical schools pursue liberation from attachment, while the classical framework of the puruṣārthas recognises kāma – desire and pleasure – as one of the legitimate aims of human life. The divine may be imagined through austere abstraction in one context and through richly embodied forms in another. A goddess may symbolize cosmic power even within societies that historically imposed profound restrictions upon actual women.

These tensions are real. Some reflect social hierarchies that deserve criticism rather than romanticization. But contradiction is not always evidence of philosophical confusion. Sometimes it reflects a different understanding of coherence.

A civilisation may remain intellectually consistent without requiring every dimension of human life to be governed by a single principle. Different ideals may apply to different circumstances because human life itself contains competing goods that cannot always be reconciled.

The modern question often becomes:

Which of these is the real Hinduism?

The older philosophical grammar might answer differently.

Why assume there could only be one?

That question reveals more than a disagreement about Hinduism. It exposes a difference in how philosophical traditions organise reality itself.

When Practice Outlives Explanation

Civilisations do not lose their philosophical grammar all at once. More often, explanations fade while practices remain.

This happens constantly in ordinary life. Families continue rituals without remembering why they began. Ceremonies are repeated because “this is how it has always been done.” Sacred words are recited in languages few participants fully understand.

None of this makes the practices meaningless.

Human communities transmit culture through far more than explicit ideas. Gesture, repetition, architecture, music, food, and ritual often preserve forms of memory that cannot easily be reduced to propositions.

Yet practices whose original rationale has faded rarely remain without explanation for long. Human beings naturally supply new ones. And those explanations frequently arise from conceptual worlds very different from the ones that first gave the practices meaning.

A symbolic gesture becomes a moral command.

A regional custom becomes universal religious doctrine.

A social convention acquires metaphysical significance.

The practice survives.

Its meaning changes.

After several generations, the newer explanation may feel as ancient as the practice itself.

The reinterpretation becomes invisible.

This is one of history’s quietest transformations. We often imagine that traditions change through dramatic revolutions. More often they change because new interpretations gradually replace older ones without anyone noticing precisely when the transition occurred.

Historical change succeeds most completely when later generations no longer recognise it as change.

The Strange Power of Codification

Modern states possess little patience for ambiguity.

Governments require categories. Courts require definitions. Schools require standardised curricula. Bureaucracies depend upon rules that can be consistently applied.

Complex traditions rarely fit comfortably within such systems.

For much of their history, Hindu traditions operated through overlapping sources of authority: regional customs, philosophical schools, commentarial traditions, ritual practices, family lineages, and sacred texts interpreted in diverse ways. Authority was distributed rather than centralized.

Modern administration demands something different.

Someone must decide what counts as authoritative. Fluid traditions must become legible. And legibility almost always requires simplification.

Colonial India illustrates this process particularly clearly. British administrators attempted to govern an extraordinary diversity of customs and beliefs through legal categories that could be uniformly administered. “Hindu law” gradually became something more fixed and systematic than the complex realities from which it had been constructed.

The immediate problem was not simply that outsiders misunderstood Indian traditions.

The more enduring consequence was that institutional simplifications gradually became social realities.

Courts enforced them.

Schools taught them.

Families adapted to them.

Political movements came to defend, or oppose, them.

With time, categories originally created for administrative convenience acquired the authority of historical inheritance. Memory then began working backwards. What had recently been standardised came to appear timeless. What had been selected came to appear complete.

One interpretation came to represent the tradition itself.

Historical change often becomes most powerful precisely because it disappears from view. Once institutions absorb a reinterpretation, later generations inherit the reinterpretation rather than the process by which it occurred.

Eventually they remember the result while forgetting the history that produced it.

When Memory Rewrites History

Why would a civilisation participate in forgetting itself?

Perhaps because civilisations, like individuals, do not remember neutrally.

Memory is never simply an archive of everything that happened. It is a selection of what allows a community to recognise itself across time. Every society inherits far more history than it can consciously preserve. Some elements are emphasized, others recede, and still others disappear almost without notice.

Modern nations face this challenge with particular urgency. A nation must tell a story that millions of strangers can recognise as a shared inheritance. Such stories inevitably simplify. A civilisation may contain centuries of argument, regional variation, competing philosophical schools, and unresolved tensions.

A national identity, by contrast, requires a narrative.

Selection therefore becomes unavoidable. Some inheritances are elevated. Others become peripheral. Some are quietly forgotten.

Modern representations of Hindu civilisation provide a particularly revealing example. Yoga travels well. Meditation travels well. Vedānta travels well. The language of ancient wisdom has become globally recognizable.

Other inheritances travel less comfortably. Erotic temple sculpture demands explanation. The place of kāma among the puruṣārthas complicates simple stories of spiritual renunciation. Gender fluidity within mythology sits uneasily beside modern moral categories.

Contextual understandings of dharma resist contemporary demands for universal rules.

None of this necessarily reflects deliberate censorship. It is more often an act of cultural curation. Every generation rearranges the past in order to make sense of the present.

The danger begins when the act of curation itself disappears from memory. What began as interpretation gradually acquires the authority of inheritance.

Memory and History

History and collective memory are related, but they serve different purposes.

History asks what happened.

Memory asks who we are.

The historian is free to discover contradiction, contingency, and change. Complexity is not a problem; it is the subject itself.

Collective memory serves another function. Communities require continuity. They seek narratives that explain not merely how they arrived here, but why they remain the same people despite centuries of change.

This difference helps explain why debates about tradition become so emotionally charged. Rarely are people defending only a particular practice. More often they are defending continuity itself.

Practices that appear ancient seem legitimate because they appear inherited. To question them can therefore feel less like historical inquiry than an attack upon the community that preserves them.

Yet history repeatedly reminds us that traditions are seldom static.

Ideas evolve. Practices adapt. Interpretations accumulate. Communities change even when they imagine themselves standing still.

Recognizing this need not weaken tradition. Indeed, it may strengthen it.

A tradition capable of acknowledging its own history possesses greater resilience than one that depends upon the illusion of timeless uniformity.

Can the Grammar Be Recovered?

Can a civilisation recover a philosophical grammar that has partly slipped from view?

Not completely.

There is no untouched past waiting to be excavated. Every attempt to understand earlier traditions begins within the conceptual world of the present. We inevitably bring our own assumptions, our own moral vocabulary, and our own historical concerns to the task.

Nor should recovery mean restoration.

The past contained wisdom, but also hierarchy. It produced profound insights alongside genuine injustices. Understanding need not become endorsement.

The purpose of recovering an older philosophical grammar is therefore not to obey it.It  is to understand the kinds of questions it made possible.

The puruṣārthas, for example, do not provide a modern political programme. Yet they ask a question that remains deeply relevant:

How can human life hold together duty, material flourishing, desire, and transcendence without reducing one to the others?

The distinction between householder and renunciant raises another question. Must every individual pursue the same moral ideal?

The contextual character of dharma poses yet another. Can ethical life remain coherent without assuming that every situation admits only one universally correct answer?

We need not accept the historical answers in order to recognise the enduring value of the questions. Perhaps recovering philosophical grammar ultimately means recovering the capacity to think in categories that history has rendered unfamiliar.

The Modern World Forgets Too

It would be comforting to imagine that this process belongs only to ancient civilisations confronting modernity.

It does not.

Modern societies also forget their own philosophical grammar.

We speak confidently of freedom, equality, rights, democracy, and progress while often disagreeing profoundly about what those words mean. Institutions survive while the arguments that originally justified them gradually fade from public memory. Political principles become slogans. Historical compromises acquire the emotional authority of timeless truths.

The process is not uniquely Hindu.

Nor is it uniquely Indian.

It is, perhaps, simply human.

No civilisation can consciously carry the entirety of its intellectual history into every generation. Forgetting is therefore unavoidable. Without selection, cultural memory would become impossible.

The danger lies elsewhere. It arises when a civilisation forgets that it has forgotten.

At that point, inherited fragments begin presenting themselves as complete systems. Recent interpretations acquire the authority of antiquity. Historical contingencies come to appear as moral necessities. Disagreement itself becomes threatening because there is no longer any memory that the tradition once contained disagreement.

This matters well beyond the study of Hinduism.

Across the world, appeals to tradition increasingly shape debates about religion, national identity, education, law, and culture. Too often these debates assume that traditions possess fixed meanings transmitted unchanged across generations. Yet traditions are rarely static. They survive precisely because they are continually interpreted, adapted, and reimagined.

Before asking whether a tradition should be defended or rejected, we may first need to ask a different question.

Do we still understand the conceptual world from which it emerged?

A civilisation does not lose itself merely because it changes. Civilisations have always changed. It loses something far more important when it can no longer remember that change was always part of how it survived.
