Voluntariness
Voluntariness is a legal and philosophical concept referring to a choice being made of a person's free will, as opposed to being made as the result of coercion or duress. Philosophies such as libertarianism and voluntaryism, as well as many legal systems, hold that a contract must be voluntarily agreed to by a party in order to be binding on that party. The social contract rests on the concept of the voluntary consent of the governed.
