4 ideas

1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual

22077	Metaphysics is the lattice which makes incoming material intelligible [Hegel]
	Full Idea: Metaphysics means nothing other than the range of general determinations of thought, the diamond lattice, as it were, into which we bring all material and thereby first make it intelligible.
	From: Georg W.F.Hegel (Philosophy of Nature (Encylopedia II) [1817], §3), quoted by Stephen Houlgate - Hegel p.95
	A reaction: This sounds to me like a perfect summary of Kant's transcendental view. Metaphysics is the a priori deconstruction of our conceptual scheme. But for Kant it is fixed, and for Hegel it is dynamic.

6. Mathematics / A. Nature of Mathematics / 2. Geometry

10245	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.

12. Knowledge Sources / A. A Priori Knowledge / 2. Self-Evidence

9379	A sentence is obvious if it is true, and any speaker of the language will instantly agree to it [Quine]
	Full Idea: A sentence is obvious if (a) it is true and (b) any speaker of the language is prepared, for any reason or none, to assent to it without hesitation, unless put off by being asked so obvious a question.
	From: Willard Quine (Reply to Hellman [1975], p.206), quoted by Paul Boghossian - Analyticity Reconsidered §III
	A reaction: This comes from someone who is keen to deny a priori knowledge, but what are we to make of the expostulations "It's obvious, you idiot!", and "Now I see it, it's obvious!", and "It seemed obvious, but I was wrong!"?

24. Political Theory / C. Ruling a State / 4. Changing the State / c. Revolution

21756	All revolutions result from spirit changing its categories, to achieve a deeper understanding [Hegel]
	Full Idea: All revolutions ...originate solely from the fact that spirit, in order to understand and comprehend itself with a view to possessing itself, has changed its categories, comprehending itself more truly, more deeply, more intimately in unity with itself.
	From: Georg W.F.Hegel (Philosophy of Nature (Encylopedia II) [1817], §246), quoted by Stephen Houlgate - An Introduction to Hegel 01
	A reaction: Some Hegelian waffle here, but it focuses on what seems important, which is how societal thinking has shifted, so that what was previously tolerated now triggers a revolution.
