In the Pali Nikāyas, the Buddha is often portrayed arguing with other wandering teachers about the biggest questions of his day: Is the world eternal or not? Does a liberated person exist after death or not? Is everything determined by past actions, or can effort change our fate? One might expect Buddhism to win those debates by offering sharper metaphysics. Instead, on many of the most charged topics, the Buddha does something more unsettling: he refuses to answer.

This refusal is not ignorance and not diplomacy. The texts give it a name: ariya tuṇhī‑bhāva, “noble silence.” Against this, they place another kind of not‑knowing: the amarāvikkhepa—the “eel‑wriggling” evasiveness—of Ajñāna skeptics, who sidestep every commitment out of fear, confusion, or opportunism. Between dogmatic certainty and slippery relativism, the Nikāyas sketch a demanding middle path: disciplined uncertainty as a spiritual practice.

To read these debates closely is to see “agnosticism” in a new light. Not as vague open‑mindedness or permanent indecision, but as a deliberately bounded sādhanā: knowing where to seek clarity, where to keep questions open, and where to set them aside because they do not help us suffer less or love better.

A Tale of Two Silences

In texts like the Tevijja Sutta and the Sāmaññaphala Sutta, we meet teachers classified as Ajñānavādins, exponents of radical skepticism. When pressed on big questions—does the self exist after death, is there another world, is there fruit of good and bad actions—they respond with a formula the texts mock as eel‑wriggling:

“If I thought it were so, I would say so. But I do not say so. I do not say it is not so. I do not say it both is and is not so. I do not say it neither is nor is not so.”

This fourfold dance might look subtle. The Buddhist redactors are not impressed. They attribute such non‑answers to motives like fear of being wrong, desire to avoid controversy, or simple muddle‑headedness. The point is not that doubt is shameful; it is that this particular style of doubt is unprincipled. It evades responsibility. It gives the comfort of never being refuted, at the price of never being able to guide anyone.

Contrast this with scenes where the Buddha is questioned on the so‑called avyākata, the “unanswered” questions. In MN 63, for example, the monk Mālunkyaputta demands to know: Is the world eternal? Finite? Is the soul the same as the body or different? Does a Tathāgata exist after death, not exist, both, or neither? If the Buddha will not answer, Mālunkyaputta threatens to disrobe.

The Buddha replies with the parable of the poisoned arrow. A man is shot and refuses treatment until he knows who shot him, what caste the archer belongs to, what kind of bow and string were used, from what wood the arrow was made. He dies with his questions intact. In the same way, the Buddha says, speculating about the eternity or finitude of the cosmos does not address the actual problem at hand: dukkha, the felt unsatisfactoriness of experience and its cessation. He refuses to answer, not because he secretly knows and is hiding it, nor because he has no view on anything. He refuses because the question does not serve liberation.

This is not eel‑wriggling. It is a refusal guided by yoniso manasikāra, “wise attention.” The Buddha will discuss right and wrong, wholesome and unwholesome, the mechanics of craving and release. He holds firm positions about karma, rebirth, and the transformative power of the path. But on questions whose answers would not change the work of ending suffering, his discipline is to keep silence.

Right View Without View‑Clinging

This creates an interesting tension. Buddhism is not neutral about “views.” The Eightfold Path begins with sammā‑diṭṭhi, right view. Some understandings are treated as crucial: that actions have consequences; that unwholesome mental states are to be abandoned; that suffering originates in craving and can be ended. At the same time, the same canon diagnoses diṭṭhi‑upādāna, clinging to views, as a form of grasping that perpetuates dukkha.

The difference lies not only in what is believed, but in how. Right view is functional and provisional: a map used for walking. View‑clinging is when we turn the map into an identity, or demand that ultimate reality confirm our concepts. The Buddha’s noble silence around the avyākata questions is a recognition that certain maps cannot be drawn with the tools of human experience at all—and that trying to draw them distracts from the urgent task of walking the path we can in fact discern.

Ajñāna skepticism fails in a different way. By constantly backing away from commitment, it never allows any map to guide action. From the Buddhist perspective, this is not humility but paralysis. It avoids the danger of fanatical certainty only by falling into the danger of never stepping forward.

This distinction helps clarify another pair of terms: vicikicchā, paralyzing doubt, versus a more skillful suspension of judgment. Doubt, in the early texts, is not ennobling in itself. It muddles the mind, saps energy, makes meditation shallow. Yet simply swapping doubt for dogma does not solve the problem. The discipline is sharper: learn to withhold judgment where knowledge is structurally unavailable or irrelevant to the cessation of suffering, and to commit where the path demands it, all while remembering that even “right” views are tools, not trophies.

Agnosticism as Sādhanā

Transposed into our own time, this suggests something more precise than “open‑mindedness.” We can think in terms of three domains.

First, there are areas where we owe ourselves and others a well‑informed stance, even if only provisional. Ethical questions about how we treat other beings; social questions where our votes, money, or silence have real effects; personal questions like whether our work harms or helps. In these spheres, pure agnosticism is not virtuous. Avoiding a position can simply mean allowing others’ positions to rule by default. Here, the Buddha’s emphasis on right view and ethical clarity pushes us toward study, dialogue, and action.

Second, there are areas where inquiry should remain genuinely open. Scientific questions at the frontiers of evidence; nuanced debates about complex social policies where data is conflicting; aspects of our own psychology we have not yet observed carefully. Here, a disciplined “I don’t know yet” is appropriate. We do not shut the door, but we also resist the pressure to pretend to know, whether for status or comfort.

Third, there are questions that function, in our lives, like the avyākata ones. For example: “Was that relationship ultimately destined or random?” “Will humanity still exist in 500 years?” “Is there a single final theory that explains consciousness?” These can be legitimate subjects of philosophical or scientific work, but for most of us, chasing them late into the night does not guide our next compassionate act. It stirs restlessness without yielding a clearer way to live.

Treating agnosticism as sādhanā means, among other things, learning to mark such questions and put them down. Not because they are forbidden, but because they do not belong in every moment. Just as we might schedule specific times for meditation or study, we can give ourselves explicit “don’t‑know zones”: stretches of practice in which the aim is not to solve anything but to notice the mind’s hunger for cognitive closure—and gently refuse to feed it.

Practicing Disciplined Uncertainty

On the meditation cushion, this can be very simple. A thought appears: “Will this practice actually work for me?” Instead of hastily reassuring yourself or catastrophizing, notice the underlying question. Is it answerable right now? Is an answer needed to maintain your commitment for the next ten minutes? If not, name it—“future outcome, currently unknowable”—and return attention to the breath or the body. This is not suppression; it is a precise act of epistemic restraint.

Journaling allows a slower, more reflective version of the same move. One can periodically write down persistent questions and sort them, not into “important” and “unimportant,” but into: must decide soon; keep exploring; consciously set aside. The point is not to resolve everything on paper. It is to become aware of which questions are functioning, for you, like the poisoned arrow’s curiosities: conditions attached to living fully that may never be met.

In conversation, the discipline becomes social. Many of us have been trained, implicitly, to treat “I don’t know” as a weakness. We bluff, we hedge, we rush to align with a side. Yet an explicit, bounded not‑knowing can change the tone of a dialogue: “I don’t know whether this policy will have the long‑term effect we hope; here’s what I do see clearly, and here’s what remains uncertain for me.” The statement carries both humility and responsibility. It acknowledges limits without abdicating the duty to act based on the best understanding available.

These practices do not aim at ignorance. They actually depend on careful attention and, in Buddhist terms, on yoniso manasikāra. The more we notice how and when we reach for premature certainty, the more we can distinguish wholesome confidence from certainty‑grasping—the anxious insistence that reality confirm our preferred picture. The reduction of suffering here is modest but real: fewer speculative spirals, less social posturing, less self‑reproach for not having omniscience.

Softening the Self Without Going Soft on Ethics

Perhaps the deepest effect of disciplined not‑knowing is on the sense of self. Our identities often congeal around views: about politics, spirituality, lifestyle, even taste. Letting certain questions remain open, or explicitly bracketed, erodes the sense that we are the sum of our positions. At the same time, maintaining clear ethical commitments—refusing, for example, to be agnostic about cruelty—prevents this softening from sliding into apathy.

Early Buddhism is unsentimental on this point. The goal is not to float above all opinions, but to see through their tendency to harden into “mine.” The Buddha’s noble silence around ultimate metaphysics serves this by refusing to let the most alluring questions become fresh objects of attachment. Ajñāna skepticism, by contrast, undermines attachment only by refusing the responsibility of commitment altogether. The path sketched in the Nikāyas walks between these: committed where it matters, restrained where it does not, and unusually clear about the difference.

To treat agnosticism as sādhanā is to bring that clarity into the small negotiations of daily life. Instead of romanticizing doubt or chasing absolute certainty, one learns to ask, again and again: In this situation, what can be known? What needs to be decided? What can be gently set down as “unanswered”—not forever, but for now, in service of a freer and more responsive heart?
