Libertarianism

In the most general sense, libertarianism is a political philosophy that affirms the rights of individuals to liberty, to acquire, keep, and exchange their holdings, and considers the protection of individual rights the primary role for the state. This entry is on libertarianism in the narrower sense of the moral view that agents initially fully own themselves and have certain moral powers to acquire property rights in external things.
