Polity, n.; pl. Polities.
Etymology: [L. politia, Gr. politie. See 1st Policy, Police.]
1. The form or constitution of the civil government of a nation or state; the framework or organization by which the various departments of government are combined into a systematic whole. Blackstone. Hooker.
2. Hence: The form or constitution by which any institution is organized; the recognized principles which lie at the foundation of any human institution. Nor is possible that any form of polity, much less polity ecclesiastical, should be good, unless God himself be author of it. Hooker.
3. Policy; art; management. [Obs.] B. Jonson.
Syn. -- Policy. -- Polity, Policy. These two words were originally the same. Polity is now confined to the structure of a government; as, civil or ecclesiastical polity; while policy is applied to the scheme of management of public affairs with reference to some aim or result; as, foreign or domestic policy. Policy has the further sense of skillful or cunning management.
Shades of meaning
Polity is the permanent system of government of a state, a church, or a society; policy is the method of management with reference to the attainment of certain ends; the national polity of the United States is republican; each administration has a policy of its own. Policy is often used as equivalent to expediency; as, many think honesty to be good policy. Polity used in ecclesiastical use serves a valuable purpose in distinguishing that which relates to administration and government from that which relates to faith and doctrine; two churches identical in faith may differ in polity, or those agreeing in polity may differ in faith. Compare law.
