Essays, by Michel de Montaigne.

Montaigne’s inquiry into custom begins with a deceptively simple observation: people rarely notice the moment a practice starts ruling them. Custom enters quietly, through repetition, and then accumulates authority. What was once difficult becomes manageable, what was strange becomes ordinary, and what was merely local begins to feel like nature itself. In this way, custom trains sensation, bodily ability, conscience, belief, and social judgment before reflective judgment has a chance to examine them.

Bodily adaptation reveals the process at its most concrete. Montaigne tells of a woman who carried a calf each day. As the animal grew into an ox, the burden remained bearable because her strength had grown with it. Repetition does not simply add effort. It changes the standard by which effort is felt. Pain, harsh weather, unusual foods, and other former irritations can become tolerable through continued exposure. Noise that first seems unbearable can disappear from the awareness of workers who live with it. A scent may please at first and then become unnoticed. Montaigne says the bells near his tower eventually stopped disturbing him, even when they rang intermittently. Familiarity can alter perception itself, making an accustomed stimulus seem almost absent.

Practice can also redirect what the body is capable of doing. An armless man learns to use his feet for tasks ordinarily assigned to hands, while another boy handles weapons and a whip with his neck and shoulders. These feats show how habit can turn an apparent lack into a practiced substitute. What looks like a fixed boundary of nature may partly be a boundary of training. Montaigne is not claiming that every limit is imaginary. He is showing how quickly experience mistakes an unfamiliar capacity for an impossible one.

The same quiet training operates in moral life, and it begins earlier than deliberate reasoning. Montaigne places great weight on infancy, nursing, play, and the child’s first surroundings. Major vices, he argues, can take root before a child understands their names. When parents praise children for hurting animals, insulting those beneath them, dominating the powerless, or cheating in games, they are not merely approving isolated acts. They are helping form dispositions toward cruelty, tyranny, and deceit. The smallness of the prize does not make cheating harmless. Whether the object is money or a trivial token, the important matter is the willingness to deceive that practice is teaching.

Custom is not inherently corrupt. The same formative power can support honesty and straightforward dealing. Montaigne attributes part of his own aversion to deceit to a childhood in which plain dealing was expected and even play was treated seriously. He presents himself as applying the same standard to small family games as to more serious contests, while watching his own conduct more strictly than the conduct of others. His point is not that habit replaces judgment with virtue automatically. It is that repeated approval and repeated disapproval prepare the ground from which later judgment grows.

Custom’s deepest authority appears in the mind. It can establish opinions so firmly that convention resembles law, reason, or conscience. People absorb local beliefs from their earliest encounters, almost as though they had received them with their milk. Whatever differs from familiar practice then seems irrational, not because it has been examined and rejected, but because it arrives without the support of familiarity. People may even remember moral instruction as advice intended for everyone else, leaving their own conduct outside the lesson. Custom’s principal power is this ensnaring effect: it makes people so much a part of an inherited practice that they struggle to step outside it and weigh it.

Comparison creates that distance. People called strange by one culture can find the customs of their critics equally strange. A Frenchman’s defense of blowing his nose with his fingers exposes how conventional disgust can be. What initially offends Montaigne becomes less offensive through familiarity. The example matters because it shows that custom does not only govern formal beliefs. It reaches into immediate bodily reactions, teaching people what to recoil from before they have supplied a reason.

The treatment of the dead makes the same point at a deeper level. Greeks and Indians reject one another’s funerary practices, while each regards its own treatment of the dead as honorable and the other’s as horrifying. Grief, reverence, and shame feel intensely personal, yet the forms through which a community expresses them are learned. A practice surrounding death can therefore appear sacred and self-evident from within one tradition, while seeming monstrous from another. The contrast does not prove that every custom is equally just. It reveals that the feeling of obviousness cannot by itself establish justice.

The mechanism extends beyond manners. Custom can organize marriage, inheritance, property, punishment, authority, bodily adornment, and religious practice. It can shape whole communities and pass their moral assumptions from one generation to the next. Inherited violence may be defended as family tradition, with later members repeating an outrage because precedent has made it intelligible. A community’s approval can thus preserve not only useful skills and social competence, but also cruelty, inequality, and oppression.

Montaigne nevertheless places an important limit on this skepticism. He says that religious matters exceeding ordinary human reason should not be judged by the same human standards as ordinary customs. Where extraordinary divine illumination is absent, human error in such matters is more excusable. This qualification does not cancel his criticism of social conventions. It marks a boundary around what human beings are competent to assess, reminding them not to treat their own reasoning as sufficient in every domain.

Custom, then, is a quiet authority that works before reflection. It can make pain ordinary, skill possible, cruelty playful, local approval feel like conscience, and unfamiliar funerary rites appear abhorrent. Long familiarity also diminishes wonder, while investigating the origin of an accepted practice may expose how weak its foundation is. Montaigne’s diagnosis is not that nature has no reality or that every convention is wrong. It is that the feeling of naturalness may be the aftereffect of repetition and communal approval, not proof that a practice is universal. Comparison does not provide a complete catalogue of better customs. It gives judgment the distance needed to distinguish what has been inherited from what has actually been examined.
