Avicenna holds that since God has existed from all eternity and is immutable and impassible, he cannot come to have an attribute or feature that he has not had from all eternity. He also claims for the simultaneous causation. A puzzle arises when we consider God’s creating this world. If God is immutable and impassible, then his attributes associated with his creating this world are unchanging. So, God must have been creating the world from all eternity. But then God’s creative (...) act, one might object, seems to be no different from a matter of natural necessity. This is a threat to divine freedom, for God would then have no choice concerning his creative action. Anthony Ruffus and Jon McGinnis argue that this puzzle can be solved in such a way that Avicenna can consistently affirm divine freedom along with divine simplicity. They suggest that Naṣīr al-Dīn Ṭūsī’s interpretation might help to show that it is false that Avicenna’s God cannot choose absolutely. For it is still open to him to choose either to create eternally or to refrain from creating anything at all. Ruffus and McGinnis argue that since creating or not creating anything at all do not correspond to two distinct concepts, Avicenna’s account of divine simplicity, which denies any multiplicity in divine mind, is safeguarded along with divine freedom. I claim that God’s omnirationality requiring that he always acts for reasons is a serious threat to such an interpretation. (shrink)
