 Generating acts upon matter and in this manner, Averroes places the principle of motion in it, because matter is “that in which the true potentiality for motion is, that is, the potentiality for receiving motion” (LC 370H). The issue was of import in Arabic and Jewish natural philosophy (MC Wolfson 669–675), while the Latin thinkers were most interested in the question how the four elements remain in the mixture, a question that Averroes also wanted to answer (Maier 1952: 28–31).
