Averroes seeks to ground philosophical theology in Aristotelian premises, by reconciling the treatment of God in metaphysics as a pure intellect with the portrayal of God in Aristotle's Physics as a cause of heavenly motion. Averroes’ solution to this problem appeals to the central Aristotelian distinction between four kinds of cause, namely formal, final, efficient, and material. In physics He is approached as an efficient cause of motion, while in metaphysics He appears as an efficient, formal, and final cause of being and unity.
