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.
