Buffered Guardians, Porous Fighters: The Self Assumed by the Laws of War

The history of international humanitarian law is usually told as a story about rules, institutions, and doctrines. It can also be told as a story about the kind of person those rules require. Not just the soldier or the lawyer in their formal role, but the deeper structure of the self that can inhabit those roles without breaking under the strain. Once that question is asked, a pattern emerges. The evolution of the laws of war tracks a shift in what sort of self the law assumes, rewards, and eventually demands. The early twentieth century still works with people whose loyalties are thick, inherited, and lived as part of the structure of reality. The late twentieth and early twenty-first centuries construct a framework that depends on a different kind of person altogether: one who can hold those same loyalties at arm’s length, examine them as objects of reflection, and, when the framework requires it, suspend them entirely.
Charles Taylor calls this the difference between the porous and the buffered self. The porous self experiences the world as something that moves through it. Its obligations are not chosen in any strong sense. They are given, constitutive, binding in the way that gravity binds. The community is not something the porous self belongs to. It is something the porous self is made of. The buffered self, by contrast, experiences itself as bounded and self-directing. Its commitments are held at a distance, available for revision, subject to the judgment of a reasoning mind that stands behind them rather than inside them. The buffered self can be loyal, can care deeply, can act from conviction. But it experiences those states as its own, as things it has in some sense chosen, rather than as forces that move through it from outside.
The buffered self is not the default condition of human beings. It is a trained capacity, sustained by specific institutions that teach people to treat their own attachments as objects of scrutiny rather than as the ground of action. Law schools, diplomatic training, international organizations, professional military culture, the entire apparatus of the post-1945 liberal order, all reproduce this stance. They reward the person who can translate loyalty into procedure, who can convert passion into a variable, who can encounter suffering without allowing prior allegiances to determine the response. The law does not simply assume this self exists. It selects for it, trains it, and produces more of it. The buffered self is as much the law’s product as its precondition.
At the turn of the twentieth century, the Hague system does not yet require this. It requires discipline, not detachment. The officer is expected to restrain himself, to follow the rules of warfare, to avoid prohibited weapons and unnecessary cruelty. But he is not expected to question the war or his place in it. His loyalty to his state and his people is not something he brackets. It is the condition of his role. The law draws a line between civilized and uncivilized ways of expressing loyalty, not between loyalty and neutrality. The officer can be fully committed, fully embedded in his national cause, and still satisfy everything the law demands, as long as he fights in the proper way.
This is a porous world, and the law works with that porosity rather than against it. The franc-tireur debates show the limit. The irregular fighter, the farmer who takes up a rifle outside a formal command structure, is excluded from protection. But the exclusion is framed in terms of conduct and organization, not in terms of the kind of self the fighter is. The officer who fights with full communal passion from within a recognized army satisfies the law entirely. His porosity is not the problem. The partisan’s failure to meet formal conditions is the problem.
The First World War broke something in this framework. The scale of destruction made it impossible to believe that professional restraint within war was sufficient. The problem was no longer how war was fought but that it was being fought at all, and by decisions made in cabinet rooms rather than on battlefields. The Kellogg-Briand Pact and then Nuremberg formalized the shift. Responsibility moved upward. The crime was aggression. The hero was the prosecutor who could stand outside his own state and judge it by a standard that transcended national interest.
That stance already presupposes a partial buffering. The prosecutor at Nuremberg must be able to see his own political community as one actor among others, subject to a law that claims to stand above the conflict. He must hold his national identity at sufficient distance to condemn its leaders. This is not the total detachment of the humanitarian guardian that comes later. It depends on victory and on the particular historical circumstances of 1945. But it marks the beginning of a new requirement. The law is beginning to ask not just for disciplined conduct but for a self capable of critical distance from its own loyalties.
The deeper transformation occurs with the 1949 Geneva Conventions. They do not ask the legal actor to judge the justice of the war. They ask him to remain neutral within it. On its face this seems more modest than the Nuremberg demand. In practice it is more radical, because it must be sustained not in the aftermath of victory but in the middle of ongoing conflict, and not by exceptional prosecutors but by an entire class of legal and humanitarian professionals.
Neutrality is not simply a rule. It is a discipline of the self. The humanitarian guardian who operates under the Geneva framework must encounter wounded enemies and treat them the same as his own wounded. He must protect prisoners regardless of what they have done. He must maintain the categories of the law when every human instinct is pulling toward the loyalties that the categories are designed to bracket. This is not something the porous self can do. For the porous self, the suffering of one’s own and the suffering of the enemy do not appear in the same register. They cannot. The community is not a preference the porous self holds. It is what the porous self is. To ask it to treat both equally is to ask it to be something other than what it is.
The humanitarian guardian, by contrast, must force the two into the same register. He must act as though the distinction that matters to everyone else in the environment, the distinction between us and them, does not determine his response. He succeeds at his role to the extent that he can maintain this suspension of his own attachments. He fails to the extent that he cannot. The framework therefore selects for, and helps produce, the buffered self. Over time it produces an entire professional culture organized around the cultivation and maintenance of that stance.
What the buffered self gains in clarity it loses in depth. It can sort. It can administer. It can hold the categories steady under pressure. But it does so by thinning out the very attachments that make violence intelligible to the people living inside it. The more successful the buffering, the more the world appears as a set of cases rather than as a set of lives. The suffering that passes through the legal categories retains its legal significance. What it loses is its particular weight, its specific texture, the quality of being the suffering of this community in this place with this history. That quality is what the porous self cannot help but feel. It is also what the buffered system cannot quite hold.
The demand is not placed only on those who administer the law. It is placed on those who seek its protection. The protected person must present herself as a certain kind of individual. She must appear as someone to whom things happen rather than as someone who acts within a collective. The more her life is entangled with a community that is fighting, the harder it is for the law to see her as innocent. The passivity requirement, which every version of the law has imposed in some form since the Hague Conventions, is not only a behavioral rule. It is an anthropological demand. It asks the protected person to perform a version of the self that the law can process: bounded, individual, detached from the political struggle around her.
This works tolerably well for certain kinds of victims. The prisoner who has been captured and is no longer fighting satisfies the requirement by circumstance. The wounded soldier who can no longer act satisfies it by incapacity. The civilian who genuinely has no role in the conflict satisfies it by fact. These are the clean cases, and the law handles them with reasonable coherence.
The hard cases are the ones the law has always struggled with. The woman who hides a fighter in her house. The man who carries food to a besieged community that includes armed defenders. The political organizer who sustains a resistance movement without personally bearing arms. The farmer who provides intelligence about troop movements. These people are not passive. Their lives are entangled with their community’s struggle in ways that are ordinary and comprehensible given what their community is facing. They do not experience themselves as having made a calculated choice to enter the conflict. They experience themselves as doing what loyalty requires, what membership demands, what any person in their situation would do. Their identity is porous. The community moves through them. They move through it.
The law sees this as a classification problem. It struggles to determine when participation begins and ends, when indirect support becomes direct, when a civilian becomes targetable. The 1977 Additional Protocols deepen the language of distinction and proportionality but do not resolve the underlying tension. The post-2001 doctrines of continuous combat function and direct participation push further into the biography of the subject, reaching toward organizational role and sustained engagement rather than specific acts. Each refinement makes the categories more precise. None of them resolves the fundamental mismatch.
What the law experiences as a problem of classification is often a problem of anthropology. It is trying to sort people whose form of life does not match the assumptions built into the categories. The categories were designed for a buffered world, a world in which individuals can choose whether to participate and can be held responsible for that choice. They encounter a porous world, in which the choice is not experienced as a choice at all but as the expression of who one is and what one’s people require. The more the law refines the rules, the more precise the mismatch becomes.
The porous self is not inherently virtuous. It can produce solidarity, courage, and the willingness to sacrifice. It can also produce cruelty, tribalism, and the inability to see the humanity of those outside the group. It binds people to each other in ways that make restraint difficult and compromise feel like betrayal. The point is not that the porous self is better than the buffered self. It is that the law has no stable place for it except as a problem to be managed, a deviation from the norm it rewards, a complication that its categories must contain or exclude.
The targeting lawyer of the contemporary era is the buffered self in its most refined form. He translates a situation saturated with political meaning into a set of legal variables. He assesses whether a target meets the threshold for continuous combat function. He calculates whether the anticipated military advantage is proportionate to the expected civilian harm. He documents the process so that the decision can be audited. He trusts the process because the process is a perfect buffer. It interposes a structure of legal reasoning between the act of killing and the person who authorizes it. The decision is not his passion or his loyalty or his judgment about the enemy. It is the output of a framework that claims to stand above all of those things.
He can kill at significant remove while remaining, in his own understanding and in the understanding of the system he serves, a neutral administrator of rules designed for the protection of humanity. He is the man who can destroy without becoming barbaric. Whether this self-understanding is accurate is a question the framework is not designed to answer.
The algorithmic targeting systems emerging from contemporary military practice carry this logic to its endpoint. The decision is made upstream, embedded in the design of the system. The analyst who builds the model, who decides which signals to weight and which thresholds to apply, exercises a form of authority that the law has not fully reckoned with. The buffering is total. No individual owns the decision in a way that generates clear accountability. The system produces outputs. Humans sign the warrants. The chain of responsibility diffuses across designers, commanders, and institutions in ways that no existing legal framework adequately tracks.
What persists through all of this is the same requirement that the law has always imposed on those who seek its protection: remain legible to a buffered system. Remain separable from your community’s struggle. Appear as an individual to whom things happen rather than as a member of a people who acts. The requirement has changed form, from behavioral compliance in 1900 to data compliance in the present. The underlying demand has not changed.
The turbulence in the laws of war today is, at one level, a doctrinal crisis about non-state actors and urban warfare and autonomous systems. At a deeper level it is a collision between two forms of selfhood. The system is built for the buffered. The world remains full of the porous. Populations under occupation, communities facing existential threat, people whose political identity is inseparable from their daily survival, do not experience their attachments as optional. They act because not acting would mean accepting outcomes that the logic of their identity makes unacceptable. The law classifies this as a problem. They experience it as fidelity.
When the stakes become existential, the buffer breaks entirely. The national protector hero who defies international courts, the community that mourns its dead as martyrs rather than as data points requiring external validation, the population that treats its own survival as a value that overrides the classifications of a system it did not design and does not trust, all of these are expressions of the porous self refusing the buffered world’s terms. The international legal order calls this a failure of maturity, a descent into the politics that the postwar settlement was designed to prevent. What it is describing is the return of a form of identity that the settlement never successfully replaced, only suppressed long enough to forget that it had not been replaced.
The sorting authority of the law is used, finally, to decide whose loyalty counts as a revocable commitment and whose loyalty is treated as a threat. The buffered self presents its neutrality as the natural condition of a mature person and its rules as the natural expression of what humanity requires. The porous self appears in this framework only at the moment it must be constrained: classified, targeted, stripped of protection for taking a direct part in a conflict it experiences not as a conflict it entered but as a condition it was born into.
If a new framework emerges from the current turbulence, it will have to address this gap more directly than any previous one has. It will have to decide whether to continue to privilege the buffered self as the implicit subject of the law, or to find a way to accommodate forms of identity in which political attachment is not something that can be held at a distance without ceasing to be that identity.
That choice, when it comes, will not present itself as a choice. It will appear, as each previous transformation has appeared, as the next necessary step in the humanization of violence. Underneath that appearance will be a decision about what kind of person the law is for, and what kind of life the law is willing to see.
