Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Euclid of Alexandria
Time is not a subject of the Elements but is presupposed as the backdrop against which mathematical reasoning unfolds. Mathematical truths are eternal and a-historical — the Pythagorean theorem is as true today as in 300 BCE. The deductive method is timeless; proofs do not depend on when they are read.
Space
Euclid of Alexandria
Space is Euclid's primary subject and is treated as substantival, infinite, flat (the fifth postulate ensures Euclidean flatness), and three-dimensional (Books XI–XIII). The parallel postulate implicitly defines flat space; its denial would not emerge for two millennia (Lobachevsky, Riemann).
Matter
Euclid of Alexandria
The Elements does not discuss matter. Geometric objects are ideal — points have no extension, lines no breadth, planes no thickness. Euclid works in a purely mathematical realm, not a physical one.
Observer
Euclid of Alexandria
The mathematical observer has immediate (non-mediated) access to geometric truth through rational intuition and deductive proof. The observer is in a sense disembodied: the truths of geometry do not depend on sensory experience. Active agency: the geometer constructs proofs and diagrams.
Energy
Euclid of Alexandria
Energy is not addressed. The Elements is a work of pure mathematics, not physics.
Information
Euclid of Alexandria
Mathematical information is substantival, conserved, and continuous. Each theorem adds to the stock of known truth without invalidating prior theorems. The axiomatic method itself is an information-conservation technology: once proved, a proposition is known forever.
Internal Tensions
Where each persona's working synthesis strains against itself.
The deepest tension in the Elements is the status of the fifth postulate (the parallel postulate). Unlike the other four postulates, it does not feel self-evident, and Euclid himself seems to have been aware of this: he delays using it until Proposition I.29 and proves everything he can without it. Twenty-two centuries of attempts to prove it from the other four failed, until Lobachevsky and Bolyai showed it was independent — inaugurating non-Euclidean geometry and ultimately Einstein's curved spacetime. Euclid's tension was the generative crack in the foundation.
