4. Formal Logic / B. Propositional Logic PL / 1. Propositional Logic
7726 Aristotelian logic dealt with inferences about concepts, and there were also proposition inferences [Weiner]
     Full Idea: Till the nineteenth century, it was a common view that Aristotelian logic could evaluate inferences whose validity was based on relations between concepts, while propositional logic could evaluate inferences based on relations between propositions.
     From: Joan Weiner (Frege [1999], Ch.3)
     A reaction: Venn diagrams relate closely to Aristotelian syllogisms, as each concept is represented by a circle, and shows relations between sets. Arrows seem needed to represent how to go from one proposition to another. Is one static, the other dynamic?
8. Modes of Existence / B. Properties / 8. Properties as Modes
16643 Accidents always remain suited to a subject [Bonaventura]
     Full Idea: An accident's aptitudinal relationship to a subject is essential, and this is never taken away from accidents….for it is true to say that they are suited to a subject.
     From: Bonaventura (Commentary on Sentences [1252], IV.12.1.1.1c)
     A reaction: This is the compromise view that allows accidents to be separated, for Transubstantiation, while acknowledging that we identify them with their subjects.
9. Objects / E. Objects over Time / 6. Successive Things
16696 Successive things reduce to permanent things [Bonaventura]
     Full Idea: Everything successive reduces to something permanent.
     From: Bonaventura (Commentary on Sentences [1252], II.2.1.1.3 ad 5), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 18.2
     A reaction: Avicenna first took successive entities seriously, but Bonaventure and Aquinas seem to have rejected them, or given reductive accounts of them. It resembles modern actualists versus modal realists.
28. God / B. Proving God / 3. Proofs of Evidence / e. Miracles
20716 False prophets will perform wonders to deceive even the elect [Mark]
     Full Idea: For false messiahs and false prophets will appear and perform signs and wonders to deceive, if possible, even the elect.
     From: St Mark (02: Gospel of St Mark [c.66], 13:22), quoted by Brian Davies - Introduction to the Philosophy of Religion
     A reaction: This casts a rather different light on the miracles of Jesus, since they were performed in a context in which even Jesus believed that lots of people (and not just the son of God) could perform miracles. Undermines any Argument from Miracles.
