Work Classification Layer
Compare Works
Pick two or more works to set their attribute fingerprints, dimension-by-dimension passages, and shared school embodiments side by side. Especially useful for author-stage comparisons (Wittgenstein early vs late) and for setting a single tradition's foundational texts against each other.

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
On Pneumatics
Time is the medium of mechanical processes. Ctesibius's water clock — his greatest invention — is literally an instrument for measuring time with unprecedented accuracy, presupposing uniform temporal flow.
Space
On Pneumatics
Three-dimensional Euclidean space: cylinders, pistons, pipes, and valves operate in definite spatial configurations.
Matter
On Pneumatics
Air and water are real substances with definite physical properties. Ctesibius's great discovery — air's compressibility and elasticity — treats air as matter that conserves substance while changing volume.
Observer
On Pneumatics
The engineer experiments, builds, tests, and iterates. Knowledge is mediated through hands-on manipulation of physical systems.
Energy
On Pneumatics
Compressed air stores energy, water pressure transmits force, springs release stored energy. Energy is finite, conserved, and reversible in the case of springs and compressed air.
Information
On Pneumatics
Technical knowledge is conservable: Ctesibius's inventions were transmitted through Philo, Vitruvius, and Hero. Ironically, his own writings did not survive — the information was conserved through secondary sources.
Internal Tensions
Where each work's argument pulls against itself.
The tension between engineering sophistication and theoretical absence: Ctesibius could build a force pump and observe that compressed air exerts force, but he had no theory of pressure, no gas law, and no concept of energy. His pneumatics is empirical engineering without theoretical mechanics.
