Republican Non-Domination: Freedom as Absence of Arbitrary Power
Quick fact
Philip Pettit’s 1997 book Republicanism sparked a global revival of the idea, and he later advised Spanish and Irish governments on institutional design—showing that non-domination is not just an ancient theory but a living framework for modern politics.
Why this is interesting
More than anything, you want to be free. The teacher can punish you for no reason—but never does. Your boss could fire you on a whim, but chooses not to. Are you free? Most of us would say yes, but republicans say no.

Understanding Republican Non-Domination: Freedom as Absence of Arbitrary Power
Think of two slaves on an island. One has a master who constantly orders them around. The other has a master who never gives orders, never interferes, but still holds absolute power. In the liberal view, the second slave is free—after all, no one is interfering. But the republican view says the second slave is still dominated: their life is lived at the mercy of another’s arbitrary will. Freedom in the republican tradition is not just about not being interfered with; it’s about not being subject to anyone who could interfere arbitrarily. So to be free, you need security from that possibility. This security comes from laws and institutions that make arbitrary power impossible—where those in power are constrained by rules, checked by others, and held accountable to the people.
A deeper explanation
The key distinction is between interference and domination. Interference is actual, concrete action—such as coercion, obstruction, or manipulation. Domination, however, is a structural relationship: you are dominated when someone has the capacity to arbitrarily interfere in your life, regardless of whether they ever exercise that capacity. Thus, a benevolent master still dominates a slave because the master’s goodwill is the only thing preventing harm. The republican tradition, rooted in Roman law (where the free person was one sui juris, not in the power of another), and developed by Machiavelli and Harrington, holds that freedom requires that no one exists in a position of unchecked power over you. This is why republicans emphasize the rule of law, separation of powers, and democratic accountability: these institutions ensure that rulers are not above the law and that their power is 'non-arbitrary'—that is, exercised according to publicly known rules and with the possibility of contestation. Non-domination therefore expands the scope of freedom beyond non-interference, requiring a positive status of civic security, but it stops short of positive liberty, which demands collective self-mastery. This framework has profound implications: it justifies a robust welfare state (to free citizens from dependency on employers, patriarchs, or patrons), and it shapes how we evaluate surveillance, labor contracts, and even criminal justice. In sum, non-domination is not merely the absence of interference but the absence of arbitrary power, achieved through political and legal institutions that protect every citizen from domination.
