The sores of the conscience do not heal

There are phrases that circulate with the borrowed authority of an ancient name, and this is one of them. “The sores of the conscience do not heal” is attributed, with the casual lightness that attributions often carry when no one bothers to check them, to the Roman mime writer Publilius Syrus. Before debating whether the quotation is genuine—and I will say in advance that there is no serious way to sustain it—it is worth lingering for a moment on what the phrase actually says, because that is where the real issue lies.

What the image puts into play

In this reading, the conscience is not a neutral faculty: it is the place where moral damage is registered, the instance that knows what the rest of the person has done. The sores are that damage turned into a wound—something that hurts from within rather than from without. And the absence of scarring is the phrase’s strong claim: that certain wounds do not close on their own, that the mere passage of time—to which so much healing power is routinely ascribed—is not enough.
It is best not to read this as a universal condemnation to eternal guilt. It is more precise, and more interesting, to distinguish the terms:

•    Guilt: the fact of having done something wrong.
•    Remorse: the fact of continuing to suffer for having done it.
•    Conscience: the capacity to recognize that damage and to judge it.
•    Scarring: the always uncertain possibility that time, repentance, or some form of reparation might transform that pain into something else.

Read this way, the phrase functions less as a moral sentence and more as an epistemological warning: beware the comfortable idea that time cures anything simply by elapsing. And behind it emerges a question more interesting than the maxim itself: what happens to someone who manages to live normally while carrying a wound that their conscience refuses to close?

An author who does not support what is attributed to him

Publilius Syrus was a writer of Syrian origin, active in Rome in the first century BCE, known for his mimes—short theatrical pieces, somewhere between comic and moralizing—and, above all, for a collection of maxims that outlived him: brief sentences on conduct, fortune, ambition, and power. But that textual tradition reached us fragmented, filtered through centuries of copies, translations, and compilations, which makes it extremely easy for a phrase to end up stuck to his name without ever having come from his pen.
Searching for the backing of “the sores of the conscience do not heal” in that corpus yields nothing. The Latin text does not appear, no ancient edition of the Sententiae contains it, and there is no identifiable translation or philological reference that would explain the passage from an original to this Spanish version. That does not prove the phrase is false—absence of evidence is not evidence of absence—but it does oblige us to treat it as what it is: an unverified attribution, perhaps a modern paraphrase that attached itself to Publilius Syrus purely by stylistic resemblance, that sententious cadence for which he is recognized.

Where the image does have a home: Montaigne

If the Roman authorship is doubtful, the idea finds a much firmer—and far more elaborated—place in Montaigne. In the chapter “Of Conscience” in the Essays, remorse appears described as an ulcer in the flesh, something that scratches and bleeds itself without anyone intervening from outside. The translation varies according to the edition, but the image in the original French—ulcère dans les chairs—is exactly the same one proposed by the phrase attributed to Publilius Syrus: remorse not as a passive memory, but as an active wound that continues to produce pain in the present tense.
Yet where the maxim attributed to Publilius Syrus is categorical—the conscience has sores, and the sores do not heal—Montaigne complicates the picture. He maintains that reason can relieve many sorrows, but not necessarily those that arise from remorse, precisely because that pain does not come from outside: it is born inside the very person who suffers it. The difference is subtle but decisive: it is not merely that the conscience remembers the damage, but that it can become the site where the damage continues to occur, in the continuous present.
And yet Montaigne does not remain in fatalism either. In other passages he distinguishes remorse from the possibility of correcting one’s conduct, and he goes so far as to affirm that a good conscience can produce satisfaction and tranquillity. The wound, then, is not a fixed destiny: it may remain open, but it may also become the ground of a reparation. Publilius Syrus—if the quotation were his, which cannot be taken as certain—would formulate the persistence of the wound as a fact. Montaigne, by contrast, examines the mechanism: how that wound is produced, what feeds it, and under what conditions it can be transformed into something else.

The tribunal that needs no witnesses

There is a scene in Montaigne that deepens the idea still further, and that is worth recovering because it best closes the argument. During the civil wars he encounters a man from the opposing side who tries to conceal it. The man is so terrified that Montaigne understands the fear does not come from any concrete external threat, but from his own conscience. From this he concludes that conscience “makes us betray, accuse, and fight against ourselves,” and that when there is no external witness, it itself becomes a witness against us.
That is, perhaps, the most uncomfortable twist in the entire trajectory: the wound does not need a judge to point it out in order to remain open. The punishment can continue even if no one accuses, no one asks, and no one remembers. Conscience is not merely the emotion of feeling guilty: it is a kind of interior tribunal that sits without an audience and without a closing date.

A possible rereading

Taken all together—the maxim of doubtful authorship, Montaigne’s ulcer, the tribunal without witnesses—the phrase that gives its title to book Flowers for Simón Latzel acquires a density that the isolated quotation did not possess. The flowers can be read as homage, as memory, even as an attempt at reparation. But the warning the phrase carries—wherever it comes from—is that an homage does not necessarily close a wound. The conscience can go on litigating with itself long after the rest of the world has considered the matter settled.
