Summary
Aristotle, Porphyry, and the old logic
Prominent among the antecedents of medieval philosophy, particularly of logic and philosophy of language, are two logical works of Aristotle's. His De interpretatione and Categories, as transmitted by Boethius and coloured by Porphyry's introduction (Isagoge) to the Categories, endowed the logica vetus with a substantial inheritance of technical terms and the metaphysical puzzles that go with them. An explanation of this inheritance requires a brief excursion into the history of the terminology central to the Isagoge and the Categories.
The terminology of the Isagoge and the Categories
Aristotle developed two loosely linked doctrines regarding the structure of propositions; one is that of the predicables, the other that of the categories (or predicaments). Chapters 4, 5, and 8 of Book I of Aristotle's Topics contain an account of the predicables definition, property, genus, differentia, and accident. A definition is a phrase signifying a thing's essence. A property is a predicate not indicating a thing's essence but predicable convertibly of it since it belongs to that thing alone; e.g., the capacity for literacy belongs exclusively to man, so that anything that has that capacity is a man, and only a man has that capacity. A genus is predicated essentially of diverse sorts of things; e.g., animal of man, ox, horse, and so forth. A differentia in combination with the genus produces the definition, as when mortal rational is added to animal to produce the definition of man.
