 Soul is the next realm in the emanative sequence, and Israeli here replicates Aristotle’s threefold division. This universal soul is made up of the higher Rational Soul, the Animal Soul and the Vegetative/Nutritive Soul and from these emanates the superlunary sphere of heaven—the point where the material world emerges from Soul. Whereas most other Neoplatonists use the term “Nature” for the corporeal world, Israeli uses the term “the sphere.” The motions of the superlunary sphere of heaven, made up of a fifth unchanging element, govern the combinations and recombinations of the four elements in the material world below the moon—hence they govern the processes of generation and corruption. Israeli’s student Dunash Ibn Tamim calls this fourth soul the soul of the sphere.
