Now on to Aristotle!

Jamers1: Let me know when you make it to Descartes.

Descartes is the man....he knew when the pigs needed bringing in.

would you mind giving us a more in-depth refresher on the subject and question?

Aristotle's Unmoved Mover and the Scholastics
I begin with the assumption that by the Scholastics you are referring to the Christian philosophers beginning with Thomas Aquinas.
Aquinas' philosophy was a response to the "taunts of the pagans" and an effort to reconcile Christian doctrine with the rediscovery of Aristotle's works by the western world after the Dark Ages.
Aquinas did not accept the Unmoved Mover per se as described by Aristotle, but instead used the Unmoved Mover argument as one of his "proofs" of the existence of the Christian God. The Unmoved Mover argument says that motion in the universe had to begin somewhere, and in order to avoid an infinite regress, there had to be an "unmoved mover". Aquinas would then argue that his proof of the Christian God was consistent with the teachings of the great philosopher Aristotle.
