Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Speusippus
Time is linear, substantival, and deterministic. Speusippus follows Plato in treating the temporal world as less fundamental than the mathematical-structural world, but unlike Plato he does not posit a separate realm of Forms existing outside time. The mathematical principles are eternal and necessary, but they are "in" the structure of the cosmos, not in a transcendent heaven.
Space
Speusippus
Space is finite (the bounded cosmos of Greek cosmology) and substantival. Speusippus posits separate principles for each level of reality — numbers, then geometrical magnitudes (points, lines, planes, solids), then soul. Space emerges at the level of geometrical magnitudes, the second tier of his ontological hierarchy.
Matter
Speusippus
Matter is relational: its ultimate constituents are not material elements but mathematical structures. The One and the indefinite dyad generate numbers; numbers generate magnitudes; magnitudes generate physical bodies. What a body "is" is determined by its mathematical form, not by its stuff.
Observer
Speusippus
The observer is both embodied (the soul is in a body) and partly disembodied (the soul has a mathematical nature that is not reducible to body). Speusippus's "scientific perception" (epistēmonikē aisthēsis) bridges sense and intellect: the trained observer perceives the mathematical structure in sensible things. Knowledge-retainment is total: the soul's mathematical nature preserves what it grasps. Metaphysical agency is cosmic-ordering — impersonal mathematical necessity, not personal providence.
Energy
Speusippus
Not independently theorised. Energy, like matter, would be a manifestation of underlying mathematical structure. Conserved and finite within the bounded cosmos. Dispersibility is unaddressed in the surviving fragments.
Information
Speusippus
Number is the fundamental informational unit — substantival, discrete, and conserved. Speusippus's mathematical ontology makes information more basic than matter: the numerical-structural "facts" about things are what make things what they are. Personal information is conserved: the soul's mathematical knowledge persists (the Academy's version of anamnēsis).
Internal Tensions
Where each persona's working synthesis strains against itself.
The governing tension in Speusippus is between his Platonic inheritance and his radical departures. He denies that the One is the Good, rejects Forms as separate substances, and treats mathematical objects as the primary realities — yet he does all this from inside the Academy, as Plato's chosen successor. Aristotle's criticism is pointed: by positing separate principles for each level of reality (numbers, magnitudes, soul), Speusippus makes the universe "episodic, like a bad tragedy" (Metaphysics 1075b37–1076a4) — a patchwork rather than a unity. Whether Speusippus had a unifying principle to answer this charge is lost with his writings.
