  Thus when an agent is determined de inesse to doing something in the future, that determination is like a disposition, and neither actual, because the event has not yet occurred, nor potential, because the possibility to do otherwise is not removed. Such a determination is not ‘actually’ in the agent’s power, Marchia grants, but it is in his power ‘dispositionally’, for although the agent cannot act before he acts, he can be disposed to act so that he will in fact act.
