Dimension-by-Dimension Evidence
What each persona's writings reveal about their stance on each of the six dimensions.
Time
Galen
Galen treats time as the linear, substantival medium of physiological process. Health and disease unfold in time; diagnosis depends on temporal sequence (the course of a fever, the stages of digestion). He does not philosophise about cosmic time or cyclical recurrence; his orientation is practical and linear. Deterministic: natural faculties operate by necessity — "Nature does nothing in vain."
Space
Galen
Space is three-dimensional, substantival, local. Galen's anatomical work is intensely spatial — the precise location of organs, the paths of nerves and blood vessels, the topology of the body. The cosmos is finite and ordered by a rational Nature. "Every part is placed where it is for a reason." (De Usu Partium, passim, paraphrase)
Matter
Galen
Matter is substantival, conserved, and finite in extent. The body is composed of four humours (blood, phlegm, yellow bile, black bile) in varying mixtures (krasis). Health is the proper balance (eukrasia); disease is imbalance (dyskrasia). Matter is local: each organ has its specific material composition suited to its function.
Observer
Galen
The human observer is an embodied, mortal being whose soul has three parts (rational in the brain, spirited in the heart, appetitive in the liver). Knowledge is mediated by the senses and by reason working on empirical data. Active agency: the physician can intervene in natural processes. Cosmic-ordering: Nature designs the body purposefully. "The best physician is also a philosopher." (Galen, That the Best Physician Is Also a Philosopher)
Energy
Galen
Pneuma (vital breath) is the vehicle of energy in the body: natural pneuma in the liver, vital pneuma in the heart, psychic pneuma in the brain. Energy is finite, substantival, conserved within the organism (through digestion and respiration), and ultimately irreversible — the body ages and dies.
Information
Galen
Anatomical and physiological knowledge is conserved through rational investigation and written tradition. Galen was intensely aware of information preservation — he wrote prolifically and mourned the loss of his library in the fire of 192 CE. Personal information is not conserved post-mortem; the soul's fate after death is a question Galen explicitly declined to settle.
Internal Tensions
Where each persona's working synthesis strains against itself.
Galen's deepest tension is between his teleological confidence — "Nature does nothing in vain" — and his empirical honesty, which forced him to acknowledge anatomical puzzles he could not explain. His eclectic philosophy (part Platonic, part Aristotelian, part Stoic) was deliberately unsystematic; he distrusted doctrinal commitment and called himself a follower of evidence rather than any school, but his teleological assumptions shaped what he was willing to see.
