Does a free agent have the power to will otherwise even at the very moment she is making a particular free choice? That is, when one is freely making some choice at a time T, does one also have the power to refrain from so choosing at T? The diachronic account of contingency and freedom says “no,” while the synchronic account says “yes.” In this paper I first address William Hasker’s criticisms of my earlier presentation of the synchronic account, and (...) then present an argument against the diachronic account. If successful, my arguments offer support for the compatibility of human freedom and divine foreknowledge. (shrink)
