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
Past, Present and Future
The 1967 mature-Prior moment of systematic tense-logical statement.
Space
Past, Present and Future
The Manchester-Oxford analytic-philosophical setting.
Matter
Past, Present and Future
The formal-logical apparatus the treatise develops.
Observer
Past, Present and Future
The presentist subject as proper observer of temporal-tense-logical structure.
Energy
Past, Present and Future
The intellectual energies of the systematic-logical-philosophical work.
Information
Past, Present and Future
The systematic content of tense logic.
Internal Tensions
Where each work's argument pulls against itself.
Prior's tense logic has become a flourishing research programme; the presentist commitments have been variously assessed across the philosophy of time.
