 When we try to consider Speusippus’ metaphysical views as they bear on the other levels of his universe, unfortunately, we have virtually nothing further to tell us what is going on: nothing that tells us either what might be the representative of the One or what the material principle might be at the level of souls, or at the level of perceptible bodies. A passage in Stobaeus (Eclogues I 49.32, Wachsmuth &amp; Hense 1884 p. 364.2–7) that apparently descends from Iamblichus’ De anima tells us that he defined the soul “by the extended in every direction”, but this continues to resist interpretation.
