Abstract
Ockham’s theory of natural rights was based on a careful definition of the basic juridical terms dominium and ius utendi, as well as on the idea of human agency and morality. By defining a right as a licit power of action in accordance with right reason (recta ratio), Ockham placed rights firmly in the agent. A right was a subjective power of action. Ockham’s theory of natural rights was influential for later natural rights theories. Its advocates included leading thinkers of the sixteenth and seventeenth centuries, whose views on the right to life, its relation to the right to property, and the state of nature resembled those ideas already developed by Ockham approximately three hundred years earlier.
