Dimension-by-Dimension Evidence

What each persona's writings reveal about their stance on each of the six dimensions.

Time

Carneades

Carneades does not advance a positive cosmology or philosophy of time. His sceptical project is epistemological: he attacks the Stoic claim that certain knowledge of the world (including temporal structure) is possible, but does not replace it with a rival theory.

Space

Carneades

Space receives no positive treatment. Carneades deploys spatial examples (the bent oar, perceptual illusions) to undermine the reliability of sense impressions, but does not theorise about space itself.

Matter

Carneades

Matter is unaddressed as a positive topic. Carneades's concern is whether we can have kataleptic (grasping) impressions of material objects — he argues we cannot — not the nature of matter itself.

Observer

Carneades

The observer is central to Carneades's epistemology: embodied, active in evaluating impressions, plural (each person must rank impressions for themselves). Knowledge is always partial and probabilistic. There is no cosmic ordering principle guaranteed to the observer — the Stoic providential cosmos is precisely what Carneades dismantles.

Energy

Carneades

Energy receives no positive treatment in the surviving testimony. Carneades's targets are epistemological and theological, not physical.

Information

Carneades

Information is implicitly perspectival and fallible: impressions convey probable information, never certain knowledge. No positive theory of cosmic information conservation is advanced.

Internal Tensions

Where each persona's working synthesis strains against itself.

Carneades

The central tension in Carneades scholarship is the "dialectical interpretation" problem: did Carneades hold positive views (e.g. probabilism as a genuine epistemology) or was he purely dialectical, arguing against the Stoics without committing to anything? Clitomachus favoured the latter reading; Metrodorus of Stratonicea and later Philo of Larissa leaned toward the former. The question remains unresolved.
