10 ideas

1. Philosophy / H. Continental Philosophy / 1. Continental Philosophy
Deleuze relies on Spinoza (immanence), Bergson (duration), and difference (Nietzsche) [May]
     Full Idea: The three tripods on which the philosophy of Deleuze stands are immanence (Spinoza), duration (Bergson), and the affirmation of difference (Nietzsche).
     From: Todd May (Gilles Deleuze [2006], 2.12)
     A reaction: [Just to begin sketching how continental philosophy sees its tradition].
4. Formal Logic / F. Set Theory ST / 1. Set Theory
Mathematical set theory has many plausible stopping points, such as finitism, and predicativism [Koellner]
     Full Idea: There are many coherent stopping points in the hierarchy of increasingly strong mathematical systems, starting with strict finitism, and moving up through predicativism to the higher reaches of set theory.
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], Intro)
'Reflection principles' say the whole truth about sets can't be captured [Koellner]
     Full Idea: Roughly speaking, 'reflection principles' assert that anything true in V [the set hierarchy] falls short of characterising V in that it is true within some earlier level.
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], 2.1)
5. Theory of Logic / K. Features of Logics / 5. Incompleteness
We have no argument to show a statement is absolutely undecidable [Koellner]
     Full Idea: There is at present no solid argument to the effect that a given statement is absolutely undecidable.
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], 5.3)
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / i. Cardinal infinity
There are at least eleven types of large cardinal, of increasing logical strength [Koellner]
     Full Idea: Some of the standard large cardinals (in order of increasing (logical) strength) are: inaccessible, Mahlo, weakly compact, indescribable, Erdös, measurable, strong, Wodin, supercompact, huge etc. (...and ineffable).
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4)
     A reaction: [I don't understand how cardinals can have 'logical strength', but I pass it on anyway]
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / d. Peano arithmetic
PA is consistent as far as we can accept, and we expand axioms to overcome limitations [Koellner]
     Full Idea: To the extent that we are justified in accepting Peano Arithmetic we are justified in accepting its consistency, and so we know how to expand the axiom system so as to overcome the limitation [of Gödel's Second Theorem].
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.1)
     A reaction: Each expansion brings a limitation, but then you can expand again.
6. Mathematics / B. Foundations for Mathematics / 4. Axioms for Number / g. Incompleteness of Arithmetic
Arithmetical undecidability is always settled at the next stage up [Koellner]
     Full Idea: The arithmetical instances of undecidability that arise at one stage of the hierarchy are settled at the next.
     From: Peter Koellner (On the Question of Absolute Undecidability [2006], 1.4)
23. Ethics / F. Existentialism / 1. Existentialism
For existentialists the present is empty without the pull of the future and weight of the past [May]
     Full Idea: For the existential view of lived time, the present would be empty if it were not for the pull of the future and the weight of the past that give it its character.
     From: Todd May (Gilles Deleuze [2006], 2.05)
     A reaction: Bergson seems to be important in developing this idea, though I suspect that Kierkegaard is a source.
24. Political Theory / D. Ideologies / 1. Ideology
Ideology is 'socially necessary illusion' or 'socially necessary false-consciousness' [Adorno, by Finlayson]
     Full Idea: Adorno defines ideology as 'socially necessary illusion' or 'socially necessary false-consciousness' (and the young Habermas accepted something like this definition).
     From: report of Theodor W. Adorno (works [1955]) by James Gordon Finlayson - Habermas Ch.1:11
     A reaction: The marxism seems to reside in the view that such things are always 'false'. If they gradually became 'true', would they cease to be ideology? Is it impossible for widespread beliefs to be 'true'?
24. Political Theory / D. Ideologies / 6. Liberalism / a. Liberalism basics
Liberal theory starts from the governed, not from the governor [May]
     Full Idea: For liberal theory, it is the individual to be governed, not the governor, who is the starting point.
     From: Todd May (Gilles Deleuze [2006], 4.02)
     A reaction: I'm inclined to see this as the single-handed achievement of Thomas Hobbes, who starts from the need of citizens to secure their contracts. Plato's society starts from entrepreneurs, but their need for a ruler seems a priori.
