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.

Dimension-by-Dimension Evidence
What each work's passages reveal about its stance on each of the six dimensions.
Time
Parts of Animals
c. 350-340 BC. The dating of Aristotle's biological works is uncertain; the consensus places them in his mature period, possibly straddling the period in Asia Minor (with Theophrastus on Lesbos, c. 347-345) and the second Athenian residence (335-322).
Space
Parts of Animals
Lyceum, Athens — Aristotle's research school. The biological observations Aristotle compiled appear to draw on direct fieldwork (in the Asia Minor period) supplemented by reports from informants throughout the Greek world.
Matter
Parts of Animals
Four-book biological treatise. Book I (methodological) plus Books II-IV (systematic-empirical) — a structure that became the template for subsequent natural-historical writing through Pliny, the medieval bestiaries, and Buffon.
Observer
Parts of Animals
Middle-to-late Aristotle. The observer is the empirical natural philosopher and the philosophical theorist of empirical inquiry — both rolled into one across the four books.
Energy
Parts of Animals
Founding-biological energies. Aristotle's biological treatises together constitute roughly a quarter of his surviving corpus; PA's methodological introduction is the most-quoted single Aristotelian text on the philosophy of biology.
Information
Parts of Animals
Four-book systematic treatise. The information-content includes both Aristotle's own observations (especially marine biology — Aristotle's Lesbos fieldwork left a lasting trace in the cephalopod observations) and material drawn from earlier sources.
Internal Tensions
Where each work's argument pulls against itself.
Together with the History of Animals and Generation of Animals, one of the founding works of biology. Darwin called Aristotle 'one of the greatest, if not the greatest, observer that ever lived' on the strength of the marine-biology observations in PA and HA. The teleological framework of PA was central to medieval scholastic natural philosophy and remained the dominant biological-explanatory framework until Darwin's reformulation.
