A glossary of political ideas

The core concepts of political thought, in plain language, with the tension each one opens up. Every idea here is a doorway into a tradition and its strongest critics.

Anarchy among states
International relations
World politics as a realm with no higher authority, where each state must provide for its own security.

The tension: Whether anarchy makes conflict inevitable or merely possible.

Ancient liberty meant sharing in collective rule; modern liberty means private independence.

The tension: Constant warned that demanding ancient civic liberty of moderns can endanger individual freedom.

Read about republicanism →

The state's authority rests on coercion, so it is illegitimate; order can arise without rulers.

The tension: Critics ask whether complex societies can hold together without a state's monopoly on force.

Read about anarchism →
Balance of power
Realism
Order kept not by law but by power checking power among rival states.

The tension: A balance can preserve peace, or tip into great-power war.
