After more than thirty years as a physician in general medicine, geriatrics, and hospice and palliative medicine, I find myself retired from clinical work and dedicating increasing amounts of time to understanding more deeply what was taking place in the care of patients, especially those living with serious illness and approaching the end of life.
Over those years, I was fortunate to work with medical residents and interdisciplinary teams of nurses, social workers, psychologists, chaplains, and other clinicians. In those settings, I sometimes drew upon the work of Martin Heidegger and Emmanuel Levinas as resources for thinking about illness, vulnerability, care, and responsibility. While our team always knew the stakes were high, my own appreciation for those stakes has deepened with the distance afforded by retirement.
Medicine, however, is not uniquely situated to address the question of personhood. The question belongs no more to medicine than to philosophy, literature, religion, or ordinary life. Yet years spent caring for people confronting serious illness, decline, and death made certain features of human experience difficult to overlook.
At first, I assumed these features belonged primarily to the circumstances themselves—to the gravity of illness, the proximity of death, or the ethical complexity of clinical care. With time, however, I began to suspect that something else was being disclosed. What appeared with particular clarity in the clinic seemed also to appear elsewhere: in ordinary conversations, fleeting encounters, family relationships, and moments that initially seemed too minor to merit much attention.
The bedside, I eventually came to think, did not reveal a special category of experience. It revealed something already present throughout ordinary life. This discussion grows out of that realization. It follows a line of experience that begins in ordinary life and asks what it may reveal about the significance of our encounters with others. Rather than offering a "theory" of personhood in the usual sense, I shall stay close to experience itself and see what becomes visible there. What emerges will not be a definition so much as a way of seeing—one that begins, as many such reflections do, with something small and easily overlooked.
I. The Moment That Linger
Late in the day, small moments tend to return.
Not the dramatic ones—the meetings that ran long or the conversations that went well—but the unfinished ones. A message left unanswered. A look held a second too long. A brief encounter that seemed, at the time, too minor to register and yet refuses, hours later, to disappear.
Nothing decisive happened. We broke no rules. If asked, we could explain ourselves easily enough. We were tired, we were distracted, we had somewhere to be. All of that is true. And yet the moment lingers.
We encounter this kind of residue often, though we rarely dwell on it. It shows up in passing interactions—with strangers, colleagues, family members, even those we barely notice until something in their presence arrests us. The feeling is not dramatic. It does not announce itself as guilt or obligation. It is quieter than that, and harder to name: a sense that something was asked of us before we had decided what, if anything, we were prepared to give.
Consider a familiar scene. A cashier says something as she hands back a receipt. We smile automatically and nod, already thinking about the next item on the day’s agenda. The exchange lasts only a few seconds. Nothing seems unusual about it. Hours later, however, the moment returns. Not because we believe we did anything wrong, but because we realize we never quite registered the person who was there. The encounter feels unfinished, though it is difficult to say why. What was it exactly she said, and was it meant for me in particular, and did she expect a response?
How about that conversation with a colleague, perhaps one nearing retirement. In the middle of an otherwise ordinary exchange, she pauses for a moment, searching for a word. We help them find it and continue talking. Only later does her hesitation return to us. What lingers is not the missing word itself but something glimpsed in that brief interruption—something about vulnerability, finitude, or simply the reality of another life unfolding alongside our own, one perhaps in which a lacuna in speech reflects a lacuna of mind.
The language we usually reach for in such moments tends to fall into two camps: explanation and obligation. We explain ourselves in terms of circumstances—what was possible, what was reasonable, what could be expected. Or we shift, just as quickly, into the language of obligation—what we should have done, what was owed, what would have been right. Both registers seem necessary. Neither one alone seems sufficient.
To say “I couldn’t” is often accurate, but it does not quite settle the matter. To say “I should have” introduces a different kind of discomfort, as if the demand exceeds anything we could realistically sustain. Between explanation and obligation, something remains unsettled.
This unsettled space is not confined to private life. It surfaces in public as well—in the way we respond to need, to vulnerability, to strangers whose lives intersect with ours briefly but decisively. We build systems to manage these encounters—rules, institutions, procedures designed to distribute responsibility fairly. And yet even when those systems function as intended, something can slip through them: a sense that the person in front of us mattered in a way no system could fully account.
We might or might not call this a matter of “personhood.” The problematic term belongs to legal debates, medical ethics, and political arguments. It appears when questions of rights or recognition become urgent enough to demand definition. But before it becomes a concept, personhood is something we experience—something that presses on us in moments that resist clean explanation.
Let’s begin our consideration from those moments, not to resolve them, but to understand why they fall upon us the way they do.
Why does explanation fail to settle them?
Why does obligation feel both undeniable and excessive?
And what, if anything, do these small, persistent encounters reveal about what it means to be a person among others?
II. The World That Already Matters
If those lingering moments are difficult to explain, it is not because they are obscure or extraordinary. It is because they arise out of something so constant we rarely notice it at all: the fact that the world already matters to us.
From the moment we wake, we are oriented. The room is not a neutral space but a place to move through. The phone is not an object but something to check. The day ahead is not an abstraction but a series of concerns already pressing—meetings, errands, conversations anticipated or avoided. Even before we begin to think about what to do, things are already at stake.
We often imagine that meaning is something we add to the world through reflection. First there is a neutral reality, and then we interpret it. But ordinary experience suggests something different. We do not wake into a collection of objects awaiting significance. We wake into concerns: The coffee is already too cold. The appointment is already approaching. The text message is already waiting for a reply. The book on the desk is already something we have been meaning to finish. Before reflection begins, the world is already organized around what matters.
This basic condition of being involved in a meaningful world was described, with unusual precision, by the German philosopher Martin Heidegger. In perhaps his most impactful work, Being and Time, Heidegger argued that we do not first encounter a collection of neutral objects and then assign them significance. Significance comes first. We find ourselves in a world where things already matter—where they show up as useful, urgent, frustrating, or irrelevant depending on the situation. This is one of Heidegger’s most enduring insights. Meaning is not primarily something we produce. It is the medium within which we already live.
A door is something to open. A delay is something that disrupts. A message is something that calls for a reply. Even indifference depends on this background of significance; it is a way of pushing something aside that already presses in.
Heidegger gave this condition a simple, yet easily misunderstood name: care. By “care,” he did not mean compassion or concern in the ordinary sense. He meant the structure of our involvement—the way our lives are always oriented toward something, even when we are tired, distracted, or withdrawn. To exist, on this view, is to be caught up in a field of meaning that we neither created nor can fully escape.
This snippet of Heidegger’s ontology helps explain why the small moments described earlier have any weight at all. They are not isolated events. They occur within a web of ongoing concerns—schedules, relationships, expectations—that give them their shape. The unanswered message matters because communication already matters. The passing encounter matters because we are already attuned to the presence of others, even when we do not consciously register it.
It also explains why explanation comes so naturally to us. When something lingers, we reach for the context that made it what it was. We reconstruct the situation: what we knew, what we didn’t know, what we could reasonably have done. These explanations are not evasions. They are attempts to situate the moment within the larger pattern of a life that is always already underway.
We find a kind of relief in all this. We are not isolated agents facing each situation from scratch. We are participants in a world that gives us bearings, even when those bearings are unstable. The pressure we feel in moments of uncertainty is not evidence of failure; it is a sign that something matters within a network of concerns we cannot simply step outside of.
Heidegger extended this insight to our relations with others. We are never alone in the world we inhabit; we are always already with others. Even when we are physically by ourselves, the structures of our lives—language, norms, expectations—are shared. We speak in words we did not invent. We follow conventions and patterns we did not design. Much of what we do each day unfolds without deliberate decision, guided by an implicit sense of what one does in situations like this.
This shared dimension of life is often comforting. It allows us to move through the world without having to deliberate at every step. But it can also flatten experience. We fall into routines. We respond as expected. We rely on scripts that carry us forward without requiring much reflection.
And in most cases, this is enough.
We answer messages when we can. We help when it is reasonable. We move on when something does not clearly concern us. Our actions make sense within the situations we inhabit, and for the most part, that sense is sufficient.
But not always.
There are moments—like the ones that linger—when this background of meaning does not quite hold. The situation still makes sense. We can still explain what happened. And yet something in the moment seems to exceed the explanation, as if the very framework that allows us to understand what we did cannot fully account for why it still troubles us.
Heidegger’s account brings us to the edge of that difficulty. It shows us why the world matters, why situations press on us, why explanation is both necessary and, in most cases, adequate.
What that account does not yet show is why, at times, adequacy is not enough. Questions remain.
Heidegger’s thinking helps us understand why situations matter. It explains why we feel pressure, why our decisions have weight, and why we naturally seek explanations when something continues to trouble us. We are situated beings, and our actions become intelligible through the situations in which they occur.
But if Heidegger’s account is sufficient, why do certain moments resist resolution even after we have understood them?
Suppose we reconstruct the situation completely. We were exhausted. We were preoccupied. We lacked the information we would have needed. Nothing more could reasonably have been expected. Sometimes these explanations genuinely settle the matter. Sometimes they do not.
The persistence of the moment cannot be explained simply by incomplete understanding. We understand perfectly well what happened. What remains unsettled is something else. It is as though the situation has been accounted for while the person has not.
The world still makes sense. The explanation remains true. Yet another dimension of the encounter continues to press upon us, one that seems strangely resistant to the very framework that otherwise illuminates so much of our experience.
It is here that another phenomenological possibility begins to emerge.
IV. The Other Who Interrupts
There is a point at which description gives way to something else—not because it fails, but because what it encounters no longer presents itself simply as something to be understood.
A woman stands at a bus stop, speaking quietly into her phone. Her tone is controlled, but strained. As we pass, we catch a fragment of the conversation—enough to register distress, not enough to grasp the details. We keep walking. There is nothing to do, no clear role to play. And yet, for a moment, her presence presses on us, as if we had been addressed without being spoken to.
The experience is peculiar because nothing has actually been requested of us. The woman does not ask for help. She may never even notice that we were there. We continue walking, and the practical situation remains unchanged.
Yet the encounter leaves behind a faint sense of exposure. For a moment, another person’s reality has impressed itself upon us without our invitation. We did not seek the encounter, and we may not know what to do with it. Nevertheless, it remains.
Experiences like this are easy to dismiss. They are fleeting, indeterminate, easily absorbed into the background of the day. But they point to something difficult to ignore: the sense that another person can matter to us in a way that does not depend on our plans, our interpretations, or even our willingness to engage.
The philosopher Emmanuel Levinas took this sense as his starting point.
Levinas did not begin, as Heidegger did, with the structure of our involvement in the world. He began with the encounter with another person—not as an object of perception, but as a presence that resists being reduced to the situation in which it appears. For Levinas, the significance of the other is not something we assign or discover through reflection. It is something that confronts us.
In his great work, Totality and Infinity (and perhaps more concisely in his Ethics and Infinity), Levinas gave a name to this encounter: the face. The term is misleading if taken too literally. Levinas did not mean the visible features of a person, nor an expression to be read or interpreted. He meant the way another person presents themselves as irreducible—as someone who cannot be fully grasped, explained, or incorporated into the frameworks we rely on to make sense of the world.
The face, in this sense, is not simply seen. It is encountered. This can sound mysterious until we notice how often it occurs in ordinary life. We may know a great deal about someone—their profession, age, history, social role, even their personality—and still feel that none of these descriptions quite exhaust who they are. The person remains more than what we know about them.
Levinas uses the language of the face to name this excess. Not an excess of information, but an excess of significance. Another person continually exceeds the categories through which we understand them. And in that encounter with the face of the other, something happens that is difficult to describe in the language of meaning or interpretation. The other person does not simply appear as part of a situation. They appear as someone to whom we are, in some way, answerable.
This answerability does not arrive as a clear instruction. It does not tell us what to do, and it does not guarantee that we will respond. It can be ignored, resisted, or rationalized away. But it has a distinctive character: it feels less like a possibility we consider and more like a demand we discover ourselves already under. This is what Levinas meant when he described responsibility as prior to choice.
Ordinarily, we think of responsibility as something we take on. We agree to help, we commit, we assume obligations. Levinas reverses this order. Before we decide anything, before we weigh options or consider consequences, we find ourselves already implicated in the presence of another person. Responsibility, in this sense, is not the result of a decision. It is what makes decision meaningful at all.
This claim can sound extreme. It seems to ask too much—to suggest that we are responsible in situations where we have neither the capacity nor the clarity to respond adequately. Levinas was aware of this tension. He did not deny the limits that structure our lives. He did not propose that we could meet every demand placed upon us.
What he insisted on was something narrower and more unsettling: that the demand itself does not originate with us, and does not disappear simply because we cannot fulfill it.
This is what gives the moments described earlier their peculiar force. The lingering unease is not just a failure of explanation. It is a trace of having been addressed—of having encountered someone whose significance exceeds the role they play in our situation.
Levinas described this relation as “asymmetrical.” The other’s claim on me does not depend on a reciprocal claim I can make on them. It does not wait to be negotiated or justified. It arrives uninvited, and it remains even when I turn away.
This does not mean that every encounter becomes ethically overwhelming. Most of the time, life proceeds as it must. We move within the limits of what we can do. We rely on systems, roles, and expectations to guide our actions. Without these structures, responsibility would be impossible to live.
But Levinas’s point is that these structures do not exhaust what happens when we encounter another person. There remains, within and alongside them, a dimension of experience in which the other appears not simply as part of the world, but as someone who places that world into question. To take that dimension seriously is not to reject the world we inhabit. It is to recognize that, within it, something can occur that is not fully contained by it.
V. Between Explanation and Obligation
If Heidegger shows us that we are always already in a world that matters, and Levinas shows us that others can matter in a way that unsettles that world, the question becomes how these two insights belong together. It is tempting to resolve the tension quickly. One might say that responsibility is simply one concern among others, to be weighed against competing demands. Or one might say that responsibility overrides all such considerations, that the presence of another person cancels the limits within which we live. Neither option quite captures the experience.
The first option risks diminishing what is most distinctive about those moments that linger—the sense that something more was at stake than a set of competing priorities. The second risks ignoring the conditions that make any response possible at all—the fact that we are finite, situated, and bound by constraints we cannot wish away. What is needed is not a resolution, but a way of holding both pressures at once.
The world we inhabit does not disappear when we encounter another person. Time does not stop. Other obligations do not vanish. The structures that guide our actions—professional roles, social norms, institutional frameworks—remain in place. Heidegger’s account makes clear that these are not superficial constraints. They are the conditions under which anything like action, understanding, or response can occur.
And yet, within those conditions, something can happen that is not reducible to them. The presence of another person can introduce a claim that does not arise from the situation as we understand it, and cannot be fully absorbed into it. This claim does not provide clear guidance. It does not tell us how to act in every case. But it changes the meaning of what we do, and of what we fail to do.
One way to describe this is to say that the world provides the space in which responsibility becomes possible, while the encounter with another person gives that space a direction it does not generate on its own. We are able to respond because we are already involved, already capable of being affected. But what calls for response—the sense that someone matters in a way that is not negotiable—does not originate in that involvement. It arrives within it.
This is why explanation and obligation coexist uneasily. Explanation situates us within the world we inhabit. It clarifies what was possible, what was reasonable, what could be expected. Obligation, by contrast, exposes the limits of that clarification. It does not negate explanation, but it refuses to let it close the matter.
To live as a person, on this view, is to inhabit that tension. Consider the following episode from clinical medicine:
A physician leaves the hospital after an unexpectedly long rounds. Every decision made that day can be justified. Resources were limited. Time was short. Other patients required attention. Yet one encounter returns unexpectedly during the drive home—a patient whose fear could not be fully addressed before the next obligation intervened.
The physician may have done everything that could reasonably have been done. Explanation is not the problem. The lingering quality of the encounter arises precisely because explanation and answerability do not coincide completely. The situation makes sense. The person still matters.
Living in the middle ground between explanation and obligation is to move through a world structured by limits, while remaining exposed to moments that exceed those limits. It is to explain oneself without expecting explanation to absolve, and to respond without believing that one’s response will ever be complete.
This is not a comfortable position. It leaves us without the reassurance that we have done enough, or that we could ever do enough. But it also resists a different kind of simplification—the idea that our responsibilities can be fully specified in advance, or discharged once and for all.Instead, personhood appears as an ongoing condition of answerability. Not a status we achieve or a role we perform, but a way of being in which we are repeatedly called upon, in ways we cannot fully anticipate, by people whose significance we do not control.
The moments that linger begin to look different in this light. They are not simply failures to act, or instances of indecision. They are traces of encounters in which something more was at stake than could be settled at the time. They persist because they register a dimension of experience that resists closure—a sense that another person mattered in a way that exceeded the situation we found ourselves in.
We do not need to resolve that excess in order to recognize it. It is enough, perhaps, to remain responsive to it—to resist the impulse to explain it away too quickly, or to convert it into a rule that can be followed without remainder.
Near the end of the day, those small moments return. Not to accuse, exactly, but to remind. We are not the authors of the claims placed upon us. But we are, nonetheless, their bearers.
Conclusion
A day unfolds. Most of it passes without incident, carried by routines that work well enough. Then something small interrupts—a glance, a question, a moment that doesn’t quite fit. We register it, or we don’t. We respond, or we move on. Either way, it leaves a trace.
It would be easy to treat these traces as noise, the residue of a life lived under pressure. There are, after all, good reasons for what we do. Time is limited. Attention is finite. No one can answer every call that presents itself. The world would be unlivable if we tried. And yet the traces persist.
These traces do not arrive with instructions. They do not tell us what we should have done, or what we must do next time. They simply remain, as a kind of quiet counterpoint to the explanations that otherwise make sense of the day. We might notice them in retrospect, when the pace slows. Or in the middle of something else, when a fragment returns without warning. A face we cannot place. A question we did not answer. A moment when we sensed, briefly, that more was at stake than we could manage at the time.
Nothing about this moment requires a theory. It does not depend on having read philosophy, or on accepting any particular account of what a person is. It is part of the ordinary texture of life among others.
But if we mull over that moment, something begins to come into view. The world we move through is not neutral. It already matters, in ways that guide us before we begin to think. Our actions make sense within that world, and for the most part, that sense is enough. We explain ourselves, and the explanations hold. Until they don’t.
When they don’t, it is not because they are false or utterly self-serving. It is because something else has entered the situation—something that cannot be fully accounted for by the roles we occupy or the limits we face. Another person appears, not only as part of the scene, but as someone whose significance exceeds it. The cashier whose words we barely heard. The stranger at the bus stop. The patient remembered long after the shift has ended. None of these encounters may require dramatic action. Nothing may come of them at all.
Yet they linger because they disclose something easy to overlook: that another person’s significance is never fully contained by the situation in which we meet them. We do not choose that excess. We encounter it. What follows from that encounter is not a rule, or a program for how to live. It is something less definite and more demanding: the recognition that our lives are not entirely our own to explain.
This recognition does not cancel the constraints we live under. It does not free us from the need to decide, to prioritize, to move on. We will continue to act as we must, within the limits that shape every day. But it may change how those limits are held.
To explain oneself is still necessary. It situates what we do within the realities we cannot ignore. But explanation no longer closes the matter. It remains open to something it cannot fully contain—a sense that, in the presence of others, there is always more at stake than can be settled.
That “more” is not an abstraction. It is what gives the smallest encounters their weight. It is what lingers when everything else has been accounted for. If there is a conclusion to draw, it may be this: not as a claim to defend, but as something to recognize.
We live among others in a way that continually exposes us to demands we did not create and cannot fully meet. We respond as we can. We explain ourselves, and often we are right to do so. And still, something remains. Not to accuse, and not to resolve, but to keep open the space in which another person can matter beyond what we can manage. By the time we notice it, we may already be there—pausing, reconsidering, feeling the slight hesitation before we move on.
It is not much. But it may be enough to begin.
