Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Protagoras of Abdera
Relational temporality of the perceiving subject; no absolute time.
Space
Protagoras of Abdera
Relational space of human practice.
Matter
Protagoras of Abdera
Standard substantival matter, with appearances relative to perceivers.
Observer
Protagoras of Abdera
Plural perceiving subjects, each the measure of their own world. No metaphysical agency ("Concerning the gods I cannot know whether they exist or what they are like" — On the Gods, fragment).
Energy
Protagoras of Abdera
Standard physics (within fifth-century BCE intellectual scope).
Information
Protagoras of Abdera
Information relative to perceivers; no personal soul-doctrine.
Internal Tensions
Where each persona's working synthesis strains against itself.
Protagoras is known almost entirely through Plato, who was committed to refuting him; the homo-mensura doctrine's precise scope (all judgments? only perceptual?) has been debated for 2,500 years. The self-refutation argument (if all truth is relative, the homo-mensura doctrine is itself only relatively true) is the standard objection Plato deploys; Protagorean replies (the doctrine is more useful or persuasive in some life-projects than in others) survive in proto-pragmatist form.
