Dimension-by-Dimension Evidence

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

⧖

Time

Opus Majus

Both eternal (divine) and created temporal order. Linear, uni-directional within nature.

✦

Space

Opus Majus

Finite, local, three-dimensional. The optics studies light propagation through physical media.

◉

Matter

Opus Majus

Substantival, conserved, local. The multiplication of species describes forms propagating through matter.

◎

Observer

Opus Majus

Embodied, active empirical observer. Knowledge requires direct sensory experience and mathematical analysis.

⚡

Energy

Opus Majus

Finite, substantival. Species-multiplication is a theory of energetic propagation through media.

⧉

Information

Opus Majus

Preserved in texts but fragile; Bacon advocates language-learning and textual correction.

Internal Tensions

Where each work's argument pulls against itself.

Opus Majus

The Opus Majus advocates experimental science but was composed for the Pope as a programme for the reform of Christian learning. The tension between empirical method and ecclesiastical authority runs through the entire work.
