Abstract
In book Λ. of the Metaphysics, Aristotle suggests that an unmoved, unmoving being (God) is the
source of all movement in the cosmos. He explains that this being instigates movement through
desire. But how does desire affect movement? And what would make Aristotle’s God an object
of desire? I attend to both questions in this paper, arguing that God’s existence as pure actuality
(energeia) is crucial to understanding God’s status as the primary and ultimate source of wonder,
and that it is as the ultimate source of wonder that we can make sense of how God affects desire.
