 Aristotle more than once complains of Speusippus’ ‘episodic’ universe: apparently the train of causality did not start with the One and go down through the various levels, but started anew at each level. This is explicit in Metaphysics VII 2, cited above: Speusippus had new principles for each level of beings. We need not suppose that the One is different at each level of being in Speusippus’ universe; the text in DCMS would have it that the One is the same principle throughout, but because of differences in what it refers to as the ‘matter’ (see quotation above), the One is realized in different ways at each level: as the number 1, or the unit, in plurality at the level of numbers, as the point, in what DCMS calls ‘place’ or, we might translate, ‘locus’, at the level of geometrical figures. The net effect is that what operates at the beginning of the arithmetical level is the realization of the One in plurality, the unit, which, as it were, represents the One at that level, and what operates at the beginning of the geometrical level is the realization of the One in locus, the point, which similarly represents the One at that level.
