Dimension-by-Dimension Evidence

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

Time

Logical Investigations (fragments)

Stoic cyclical cosmic time; logical truths hold across conflagrations.

Space

Logical Investigations (fragments)

The Stoic finite cosmos; logical structure is independent of spatial location.

Matter

Logical Investigations (fragments)

Stoic corporeal ontology; the lekton (sayable) is notably incorporeal — a rare exception.

Observer

Logical Investigations (fragments)

The rational agent who grasps propositions and follows valid inferences.

Energy

Logical Investigations (fragments)

Stoic pneuma and conflagration cycle.

Information

Logical Investigations (fragments)

Discrete propositions (lekta) as the bearers of logical content; foundational for information-theoretic semantics.

Internal Tensions

Where each work's argument pulls against itself.

Logical Investigations (fragments)

The incorporeal status of the lekton sits uneasily with Stoic corporeal ontology; the relationship between Stoic logic and Stoic physics remains a subject of scholarly debate.
