The purpose of this article is to explore John Duns Scotus's thought on Freedom, in order to achieve some elements that might be useful for a systematic study. Starting from the distinction between natural and free active potencies, it shows what is more specific of Freedom. Being a pure perfection, for Scotus, it can be applied to God and creatures as well. After exposing the content and origin of the distinction, the article provides an account of Duns Scotus's thought on Divine Freedom. Insofar as Freedom is infinite, it is compatible with necessity. At the same time, as God is creator of the contingent and finite world, his Freedom is capable of contingent actions. Finally, human Freedom is studied as an important part of the image of God in human beings. The Franciscan's conception of Freedom makes it possible to overcome the idea that it depends either on the imperfection of the contingent world or on the imperfection of our knowledge about it. Moreover, it shows that Freedom has an act of its own and thus it is more than a mere corollary of knowledge.
