Dimension-by-Dimension Evidence

What each work's passages reveal about its stance on each of the six dimensions.

⧖

Time

Elements

Mathematical truths are eternal and a-historical. The Pythagorean theorem is as true today as in 300 BCE. Time is presupposed but not theorised.

✦

Space

Elements

Space is Euclid's subject: infinite, flat (the fifth postulate ensures Euclidean flatness), three-dimensional (Books XI–XIII). The parallel postulate implicitly defines flat space.

◉

Matter

Elements

Not addressed. Geometric objects are ideal — points have no extension, lines no breadth.

◎

Observer

Elements

The geometer has immediate access to truth through rational intuition and deductive proof. In a sense disembodied: geometric truths do not depend on sensory experience.

⚡

Energy

Elements

Not addressed. The Elements is pure mathematics, not physics.

⧉

Information

Elements

Mathematical information is conserved and cumulative. Each theorem adds to the stock of known truth. The axiomatic method is an information-conservation technology.

Internal Tensions

Where each work's argument pulls against itself.

Elements

The status of the fifth postulate: it does not feel self-evident, and Euclid delays using it until I.29. Twenty-two centuries of failed attempts to prove it led to non-Euclidean geometry and ultimately to Einstein's curved spacetime.
