Justice (virtue)

Justice is love working at scale — the shape charity takes between strangers.


Where It Belongs

Justice is the second of the four cardinal virtues, alongside Prudence, Fortitude, and Temperance — the list that begins in Plato's Republic and runs through the Stoics into Aquinas. See Stoicism, where justice governs everything owed to others. For Plato it was the crowning virtue, and his definition is worth keeping: justice is each part doing its own work — in the city, each class; in the soul, reason, spirit, and appetite each in right relation. Injustice, on this reading, is not first a crime but a disorder: something in the whole usurping a place that is not its own.

What It Is

The Roman jurists compressed it into a formula the Middle Ages never improved: justice is the constant and perpetual will to render to each what is due — suum cuique, to each their own. Two words in that formula carry the weight. It is a will, a settled disposition rather than an occasional mood of fairness; and it is constant, extending to people one dislikes, cases where one loses, and days when no one is watching. Among the cardinal virtues it is the only one aimed wholly outward — prudence perfects one's seeing, fortitude and temperance one's passions, but justice exists entirely in relation, which is why the tradition ranked it highest of the moral virtues.

Its Opposite

Justice has no single deadly sin as its opposite — injustice is rather the social form of every sin: Greed takes what is another's due, Envy resents it, Wrath seizes the judge's bench, Pride exempts the self from the law it applies to others. That breadth is the point. Where the remedial virtues each answer one passion, justice answers the sum of their damage.

The Tarot Echo

The vault's Justice card carries the virtue into the Major Arcana — the crowned figure with sword and scales, weighing exactly, cutting cleanly. Card and virtue agree on the essentials: measure before the blade, and no thumb on the scale.



To each what is due — constantly, perpetually, especially when it costs.
