Positive liberty

Freedom understood as the capacity to act on one's own will and fulfill one's potential, which may require resources or public support.

Also called: freedom to, positive freedom, self-mastery

Positive liberty is the idea that real freedom means having the power and opportunity to control one's own life and pursue one's goals, not just being free of interference. On this view, conditions such as poverty, ignorance or illness can limit freedom as surely as laws do.

Philosophers such as T.H. Green and, in a different way, Rousseau and Hegel developed versions of it. Isaiah Berlin contrasted it with negative liberty in "Two Concepts of Liberty" (1958). Franklin D. Roosevelt's "Four Freedoms," which included freedom from want and fear, reflect a positive conception, and it supports arguments for public education, health programs and the welfare state.

Advocates say it gives content to freedom and justifies government action to expand opportunity. Critics, including libertarians and many conservatives, warn that defining freedom as capacity invites government to decide what people need to flourish, and that it can slide into coercion in the name of a "higher" self. Berlin worried about the latter. Conservatives who favor equality of opportunity often stress that opportunity should come through families, schools and work rather than state redistribution.
