Minor Logic Tape #8 Tree of Porphyry: An arrangement of the most important concepts of philosophy in such a way as to express vividly a certain hierarchy of universality which orders and significantly relates these concepts to each other. Father Feeney’s Method of Memorizing Using Numbers: 1. One purpose of logic is Truth. 2. Two types of Argument: Inductive & Deductive 2. Three acts of the Mind: Simple Apprehension, Judgment, Inference 4. Four types of Categorical Propositions A, E, I, O. (Brother Francis Notes, paragraph 29) 5. Five Predicables: Genus, Species, Differentia, Property, Logical Accident. 6. Six Transcendental Ideas that go above the Categories: Being, Thing, Something, One, True, Good. 7. Seven Liberal Arts: Grammar, Logic, Rhetoric (Trivium), Arithmetic, Astronomy, Geometry, Music (Quadrivium) 8. Eight Rules of the Syllogism (see Chapter IX of Brother Francis’s Logic Notes) 9. Nine Accidents: Quantity, Quality, Relation, Action, Passion, Time, Place, Disposition, Habitus. 10. Ten Categories: The Nine Accidents plus Substance. 14. Fourteen Modes or Moods of the Syllogism (Brother’s Logic Notes, par. 46) Three Orders that Logic is Involved with: Individual things, Thought (First Universals or the “Logical Whole”) and the Expression of Thought (Words) First Intention: Think of the reality represented by the idea. Second Intention: Think of the idea itself. Ten Categories: The highest Genera—the limit of univocal predication. When we define, we go UP the Porphyrian Tree and we make the object more intelligible; but when we divide, we go DOWN the Porphyrian Tree and we make it more familiar. Species: Names the complete essence of a thing. (For example, when you call someone a “man” you name the complete essence, versus when you say he is a “body.”) Man is the only species that can be fully defined (in the physical order).
