3 ideas

1. Philosophy / A. Wisdom / 1. Nature of Wisdom
Theory vanishes when one has obtained wisdom [Rahulabhadra]
     Full Idea: As the drops of dew in contact/ With the sun's rays disappear,/ So all theorizings vanish,/ Once one has obtained wisdom.
     From: Rahulabhadra (Hymn to Perfect Wisdom [c.150], v 10)
     A reaction: I suspect that the western view is that wisdom is good theory. This sounds like the sort of thing Wittgenstein would have said. Remarks like this encourage people to skip study, with the illusion that they can go straight to wisdom.
4. Formal Logic / F. Set Theory ST / 4. Axioms for Sets / a. Axioms for sets
ZFC could contain a contradiction, and it can never prove its own consistency [MacLane]
     Full Idea: We have at hand no proof that the axioms of ZFC for set theory will never yield a contradiction, while Gödel's second theorem tells us that such a consistency proof cannot be conducted within ZFC.
     From: Saunders MacLane (Mathematics: Form and Function [1986], p.406), quoted by Penelope Maddy - Naturalism in Mathematics
     A reaction: Maddy quotes this, while defending set theory as the foundation of mathematics, but it clearly isn't the most secure foundation that could be devised. She says the benefits of set theory do not need guaranteed consistency (p.30).
22. Metaethics / A. Ethics Foundations / 2. Source of Ethics / h. Expressivism
Moral words have an inherited power from expressing attitudes in emotional situations [Stevenson,CL]
     Full Idea: A term is moral because of the power that the word acquires, on account of its history in emotional situations, to evoke or directly express attitudes, as distinct from describing or designating them.
     From: Charles Leslie Stevenson (Ethics and Language [1944], p.33), quoted by John Hacker-Wright - Philippa Foot's Moral Thought 1 'Ayer'
     A reaction: Invites the question of what the words meant before they acquired this patina of historical usage. If 'good' orginally meant 'hurray!', its repeated usage doesn't seem to change that. If it was descriptive, why would that change with time?
