"Justice is the set and constant purpose which gives every man his due"
About this Quote
Cicero’s definition doesn’t romanticize justice; it weaponizes it. “Set and constant purpose” sounds like a moral motto, but it’s really a political demand: justice isn’t a mood, a verdict, or a burst of compassion. It’s a disciplined stance, the kind that has to survive boredom, pressure, and factional heat. In the late Roman Republic, where law was routinely bent by patronage, bribery, and battlefield celebrity, that insistence on steadiness reads like a rebuke to the ruling class’s improvisational ethics.
The sharper edge is in “gives every man his due.” “Due” implies an existing ledger, a social arithmetic. Cicero isn’t describing justice as radical equality; he’s describing it as rightful distribution. That’s the Roman genius and the Roman trap: justice as order. The phrase flatters the system by implying that everyone already has a proper place, and the just person merely restores the correct allocation. It’s a stabilizing definition, not a liberating one, and it conveniently aligns with Cicero’s broader project of defending republican institutions while fearing populist upheaval.
Subtext: justice requires intention, not just outcome. You can accidentally do the right thing; you can’t accidentally be just. That makes the concept harder, almost prosecutorial: if your “purpose” is corrupted by self-interest or tribal loyalty, your “justice” is a costume. Cicero is offering a standard meant to outlast demagogues and strongmen, even as he watched Rome slide toward exactly that.
