4. Formal Logic / C. Predicate Calculus PC / 3. Completeness of PC
Gödel proved the completeness of first order predicate logic in 1930 [Gödel, by Walicki]
     Full Idea: Gödel proved the completeness of first order predicate logic in his doctoral dissertation of 1930.
     From: report of Kurt Gödel (Completeness of Axioms of Logic [1930]) by Michal Walicki - Introduction to Mathematical Logic History E.2.2
9. Objects / B. Unity of Objects / 2. Substance / d. Substance defined
Substance needs independence, unity, and stability (for individuation); also it is a subject, for predicates [Perkins]
     Full Idea: For individuation, substance needs three properties: independence, to separate it from other things; unity, to call it one thing, rather than an aggregate; and permanence or stability over time. Its other role is as subject for predicates.
     From: Franklin Perkins (Leibniz: Guide for the Perplexed [2007], 3.1)
     A reaction: Perkins is describing the Aristotelian view, which is taken up by Leibniz. 'Substance' is not a controversial idea, if we see that it only means that the world is full of 'things'. It is an unusual philosopher wholly totally denies that.
24. Political Theory / A. Basis of a State / 4. Original Position / b. Veil of ignorance
You can't distribute goods from behind a veil, because their social meaning is unclear [Walzer, by Tuckness/Wolf]
     Full Idea: Walzer says behind the veil of ignorance there would be no way to know how a particular good should be distributed, because we would not know the social meaning of the good in question.
     From: report of Michael Walzer (Spheres of Justice [1983]) by Tuckness,A/Wolf,C - This is Political Philosophy 4 'Communitarian'
     A reaction: Is Rawls actually proposing to decide details of distribution from behind the veil? There is just the maximin principle. What that means in practice would surely come once the society was under way.
25. Social Practice / B. Equalities / 2. Political equality
Complex equality restricts equalities from spilling over, like money influencing politics and law [Walzer, by Tuckness/Wolf]
     Full Idea: Complex equality tries to keep advantages in one area (such as money) from translating into advantages in politics or before the law.
     From: report of Michael Walzer (Spheres of Justice [1983]) by Tuckness,A/Wolf,C - This is Political Philosophy 3 'Complex'
     A reaction: Put like that, Walzer's complex equality becomes very interesting, and pinpoints a major problem of our age, where discrepancies of wealth have become staggeringly large at the top end.
25. Social Practice / B. Equalities / 4. Economic equality
Equality is complex, with different spheres of equality where different principles apply [Walzer, by Swift]
     Full Idea: Michael Walzer argues for 'complex equality', saying different goods belong to different distributive 'spheres', each with its own distributive principles.
     From: report of Michael Walzer (Spheres of Justice [1983]) by Adam Swift - Political Philosophy (3rd ed) 3 'Egalitarian'
     A reaction: Sounds interesting. Equality seems to make different demands when it concerns basic food for survival, or fine wines. You can spend your money freely, but hording in a crisis is frowned on.
