In philosophy (particularly the theory of categories), the Porphyrian tree (also spelled Porphyrean tree) or Tree of Porphyry is a classic device for illustrating a "scale of being" (Latin: scala praedicamentalis), attributed to the 3rd-century CE Greek neoplatonist philosopher and logician Porphyry, and revived through the translations of Boethius. Porphyry suggests the tree in his introduction ("Isagoge") to Aristotle's Categories.
