Compare Works
Pick two or more works to set their attribute fingerprints, dimension-by-dimension passages, and shared school embodiments side by side. Especially useful for author-stage comparisons (Wittgenstein early vs late) and for setting a single tradition's foundational texts against each other.
On the Natural Faculties

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
On the Natural Faculties
Physiological time is linear, deterministic, and directional: digestion, growth, and decay proceed in ordered sequence. Nature's faculties operate by necessity — "Nature does nothing in vain." Galen does not address cosmic time; his concern is the temporal unfolding of biological process.
Space
On the Natural Faculties
Anatomical space is Galen's domain: three-dimensional, substantival, local. Each organ occupies a specific position adapted to its function. "The kidneys are placed where they are for a reason — to draw the urine from the blood." (On the Natural Faculties I.13, paraphrase)
Matter
On the Natural Faculties
Matter is substantival, conserved, and local. The body transforms food into blood, bile, and tissue through the four natural faculties. The four humours (blood, phlegm, yellow bile, black bile) are the material basis of health and disease.
Observer
On the Natural Faculties
The physician-observer is embodied, active, and engaged in empirical investigation. Knowledge is mediated by dissection, clinical observation, and rational inference. Cosmic-ordering: Nature designs the body purposefully. "The best physician is also a philosopher." (Galen, separate treatise)
Energy
On the Natural Faculties
The natural faculties are the energetic principles of the body — attraction, retention, alteration, expulsion. Energy is finite, conserved within the organism, and ultimately irreversible (the body ages and dies).
Information
On the Natural Faculties
Anatomical knowledge is conserved through demonstration and written tradition. Galen is intensely concerned with the accurate transmission of medical knowledge. Personal information (the individual patient's constitution) is important clinically but not conserved metaphysically.
Internal Tensions
Where each work's argument pulls against itself.
The treatise's deepest tension is between Galen's teleological confidence and his empirical method. He insists on observation and demonstration but interprets everything through the lens of "Nature does nothing in vain" — which is a metaphysical commitment, not an empirical finding. His polemic against the atomists is sometimes more rhetorical than evidential.
