Dimension-by-Dimension Evidence

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

Time

Sextus Empiricus

The Pyrrhonist suspends judgment on the nature of time. Sextus devotes extensive arguments to showing that time cannot be coherently said to be limited or unlimited, divisible or indivisible, generated or ungenerated. "If time is something, it is either limited or unlimited … but each of these has been problematised; therefore time is not something." (Adversus Mathematicos VI.66, paraphrase) — but even this conclusion is held tentatively.

Space

Sextus Empiricus

Sextus applies the same sceptical strategy to place and void: arguments for and against the existence of place cancel out. "Some say place exists, some say it does not, some say it is unclear — we, because of the equal force of the opposing arguments, suspend judgment." (Outlines III.119, paraphrase)

Matter

Sextus Empiricus

The ten modes demonstrate that the qualities we attribute to matter depend on the perceiver's condition, position, and culture. Whether matter has an independent nature cannot be affirmed or denied. "We cannot say what the external object is like in its nature, but only how it appears." (Outlines I.59)

Observer

Sextus Empiricus

The observer is the embodied, situated perceiver whose impressions are the only starting point. Knowledge is immediate (we know only appearances), partial (we cannot reach the thing itself), and the observer is passive — the sceptic yields to appearances without asserting their truth. No metaphysical agency is postulated. "The sceptic does not dogmatise … he goes by what appears." (Outlines I.13)

Energy

Sextus Empiricus

Sextus does not develop a theory of energy; arguments about causation, motion, and force are marshalled only to show their insolubility. "If cause exists, it either acts on its own or needs another cause … the argument proceeds to infinity." (Outlines III.20, paraphrase)

Information

Sextus Empiricus

Information is emergent — it is a function of appearances to a perceiver — and non-conserved: the sceptic makes no claim that knowledge accumulates or persists. Personal knowledge dissolves with the suspension of judgment. "We do not overthrow the affective impressions that lead us involuntarily to assent." (Outlines I.13, paraphrase)

Internal Tensions

Where each persona's working synthesis strains against itself.

Sextus Empiricus

The deepest tension in Pyrrhonism is the self-referential problem: is the claim "one should suspend judgment on all claims" itself a claim on which we should suspend judgment? Sextus is well aware of this and offers the metaphor of the ladder kicked away — the sceptical arguments "cancel themselves along with the things to which they are applied, just as purgative drugs expel themselves along with the bodily humours" (Outlines I.206). Whether this move is coherent or question-begging remains debated.
