9 ideas

11. Knowledge Aims / A. Knowledge / 7. Knowledge First

23888	Knowledge is beyond question, as an unavoidable component of thinking [Weil]
	Full Idea: The speaker refuses to pose the question of knowledge, since knowledge is a given that is mixed with thought, and that no thinking being can get away from.
	From: Simone Weil (Philosophy [1941], p.42)
	A reaction: On the whole I favour belief-first, but I take the primary purpose of minds to be navigation, and that needs facts, not hopeful beliefs. Weil's thought pushes me a bit towards the knowledge first view.

12. Knowledge Sources / E. Direct Knowledge / 4. Memory

21500	We rely on memory for empirical beliefs because they mutually support one another [Lewis,CI]
	Full Idea: When the whole range of empirical beliefs is taken into account, all of them more or less dependent on memorial knowledge, we find that those which are most credible can be assured by their mutual support, or 'congruence'.
	From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 334), quoted by Erik J. Olsson - Against Coherence 3.1
	A reaction: Lewis may be over-confident about this, and is duly attacked by Olson, but it seems to me roughly correct. How do you assess whether some unusual element in your memory was a dream or a real experience?

21501	If we doubt memories we cannot assess our doubt, or what is being doubted [Lewis,CI]
	Full Idea: To doubt our sense of past experience as founded in actuality, would be to lose any criterion by which either the doubt itself or what is doubted could be corroborated.
	From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 358), quoted by Erik J. Olsson - Against Coherence 3.3.1
	A reaction: Obviously scepticism about memory can come in degrees, but total rejection of short-term and clear memories looks like a non-starter. What could you put in its place? Hyper-rationalism? Even maths needs memory.

13. Knowledge Criteria / B. Internal Justification / 4. Foundationalism / a. Foundationalism

6556	If anything is to be probable, then something must be certain [Lewis,CI]
	Full Idea: If anything is to be probable, then something must be certain.
	From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 186), quoted by Robert Fogelin - Walking the Tightrope of Reason Intro
	A reaction: Lewis makes this comment when facing infinite regress problems. It is a very nice slogan for foundationalism, which embodies the slippery slope view. Personally I feel the emotional pull of foundations, but acknowledge the very strong doubts about them.

13. Knowledge Criteria / B. Internal Justification / 5. Coherentism / b. Pro-coherentism

21498	Congruents assertions increase the probability of each individual assertion in the set [Lewis,CI]
	Full Idea: A set of statements, or a set of supposed facts asserted, will be said to be congruent if and only if they are so related that the antecedent probability of any one of them will be increased if the remainder of the set can be assumed as given premises.
	From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 338), quoted by Erik J. Olsson - Against Coherence 2.2
	A reaction: This thesis is vigorously attacked by Erik Olson, who works through the probability calculations. There seems an obvious problem without that. How else do you assess 'congruence', other than by evidence of mutual strengthening?

18. Thought / C. Content / 8. Intension

5828	Extension is the class of things, intension is the correct definition of the thing, and intension determines extension [Lewis,CI]
	Full Idea: "The denotation or extension of a term is the class of all actual or existent things which the term correctly applies to or names; the connotation or intension of a term is delimited by any correct definition of it." ..And intension determines extension.
	From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946]), quoted by Stephen P. Schwartz - Intro to Naming,Necessity and Natural Kinds §II
	A reaction: The last part is one of the big ideas in philosophy of language, which was rejected by Putnam and co. If you were to reverse the slogan, though, (to extension determines intension) how would you identify the members of the extension?

21. Aesthetics / B. Nature of Art / 1. Defining Art

23887	Art (like philosophy) establishes a relation between world and self, and between oneself and others [Weil]
	Full Idea: Isn't true art a method for establishing a certain relation between the world and the self, and between oneself and others, and isn't that the equivalent of philosophy?
	From: Simone Weil (Philosophy [1941], p.38)
	A reaction: I hope the definition of 'true' art doesn't have to conform to achieving this relation. I suppose each good work of art shows you a distinctive way of relating to the world. An interesting thought (as so often with this thinker).

29. Religion / B. Monotheistic Religion / 4. Christianity / d. Heresy

16713	Philosophers are the forefathers of heretics [Tertullian]
	Full Idea: Philosophers are the forefathers of heretics.
	From: Tertullian (works [c.200]), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 20.2

29. Religion / D. Religious Issues / 1. Religious Commitment / e. Fideism

6610	I believe because it is absurd [Tertullian]
	Full Idea: I believe because it is absurd ('Credo quia absurdum est').
	From: Tertullian (works [c.200]), quoted by Robert Fogelin - Walking the Tightrope of Reason n4.2
	A reaction: This seems to be a rather desperate remark, in response to what must have been rather good hostile arguments. No one would abandon the support of reason if it was easy to acquire. You can't deny its engaging romantic defiance, though.
