 Simon seems to hold a twofold account of individuation: there is individuation by a quantitative division of matter, which explains the individuation of material beings; and individuation by subsistence, which explains the individuation of immaterial beings such as celestial bodies, intelligences and the human intellect. Simon undoubtedly introduces his twofold account to circumvent the Averroistic solution to the question of the individuation of superior beings via the introduction of spiritual matter.
