Aristotle
384–322 BC · Ancient Greek
Liberty is self-government: ruling and being ruled in turn among equals.
Aristotle conceives of liberty primarily in political terms. The free person is one who lives in a polis governed by law and who participates in ruling and being ruled in turn. The slave, who is permanently subject to the rule of another without any share in government, lacks the condition of the free man. Liberty, on this view, is not merely the absence of constraint but a specific form of political life: shared self-government among citizens who are by nature equals.
Aristotle also treats the question of liberty in its moral aspect, as the capacity for voluntary action. A person is responsible only for what he does willingly, with knowledge of the relevant circumstances. Actions performed under compulsion or through ignorance are not fully voluntary and therefore not fully the agent's own. This analysis of voluntary action, treated more fully in the chapter on WILL, lays the groundwork for what later writers develop as the distinction between free will and determinism, though Aristotle does not himself frame it in those terms.
There is, further, a connection in Aristotle between liberty and virtue. The person who is governed by appetite is, in an important sense, no freer than the person who is governed by another man. Liberty in its fullest sense requires that reason govern desire, and that rational citizens deliberate together about the common good. On this account, liberty, like virtue, is an achievement of character and political order, not simply a natural condition. The bearing of this conception on the questions treated in the chapter on SLAVERY is evident.
"The basis of a democratic state is liberty... one principle of liberty is for all to rule and be ruled in turn."
"A man is the origin of his actions; and deliberation is about the things to be done by the agent himself."
Aristotle thus introduces two strands that run through the subsequent discussion of liberty: political liberty as self-government among equals, and moral liberty as the rational governance of one's own actions. The relation between these two conceptions, and whether they are ultimately compatible, becomes a central question in the tradition.
