Dimension-by-Dimension Evidence

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

Time

Theaetetus

Time is presupposed but not directly engaged. The wax tablet and aviary models give temporal accounts of memory and recollection.

Space

Theaetetus

Not engaged.

Matter

Theaetetus

Heraclitean flux is engaged via Protagoras — the world of perceptible things is in constant change, against which the dialogue seeks stable knowledge.

Observer

Theaetetus

The Platonic observer of the Theaetetus is the rational soul seeking knowledge. Active, plural at the empirical level, capable of knowledge in principle through dialectic.

Energy

Theaetetus

Not engaged.

Information

Theaetetus

The Forms remain the substantival informational background, even though the dialogue ends without positive doctrine. Personal information conserved (the Platonic immortal soul).

Internal Tensions

Where each work's argument pulls against itself.

Theaetetus

The dialogue's aporetic ending — three definitions tried and rejected — has been read in opposite ways: as Platonic Socratic humility, or as a positive signal that knowledge requires the Forms (which the dialogue presupposes without explicitly invoking). Modern epistemology (Gettier and the post-Gettier literature) treats the JTB analysis as a real philosophical position, not just a refuted definition.
