Abstract

Medieval philosophers admit a physical indeterminacy of natural powers, because they can be determined by something else. However, rational powers have a metaphysical form of indeterminacy, which allows the will to be determined by reason (Thomas Aquinas), or to determine itself (Duns Scotus). Yet, what distinguishes the two main forms of self-determination in Duns Scotus - the unlimited will and the infinite God? In finite beings, the will is unlimited because it always depends on something else, on an object that is a partial cause of its determination, whereas God depends only on Himself for self-determination. Hence, the concepts of indeterminacy, unlimitedness and infinity are strictly distinct in Duns Scotus.
