4. Formal Logic / E. Nonclassical Logics / 7. Paraconsistency
Paraconsistent reasoning can just mean responding sensibly to inconsistencies [Jago]
     Full Idea: A practical application of paraconsistent reasoning is in large databases. It does not mean that contradictions could be true, but only that we sometimes need to draw sensible conclusions from inconsistent data. 'Dialethists' believe some contradictions.
     From: Mark Jago (Paraconsistent Logic [2010])
     A reaction: Interesting as a more cautious and sensible attitude to the scandal of paraconsistency.
6. Mathematics / A. Nature of Mathematics / 2. Geometry
One geometry cannot be more true than another [Poincaré]
     Full Idea: One geometry cannot be more true than another; it can only be more convenient.
     From: Henri Poincaré (Science and Method [1908], p.65), quoted by Stewart Shapiro - Philosophy of Mathematics
     A reaction: This is the culminating view after new geometries were developed by tinkering with Euclid's parallels postulate.
23. Ethics / C. Virtue Theory / 4. External Goods / d. Friendship
The Greek 'philia' covers all good and fruitful relationships [Cooper,JM]
     Full Idea: The Greek 'philia' is much wider than our "friendship"; it includes family relationships, and business relationships and membership of institutions.
     From: John M. Cooper (Aristotle on Friendship [1977], p.301)
