1. Philosophy / F. Analytic Philosophy / 1. Nature of Analysis
Analysis must include definitions, search for simples, concept analysis, and Kant's analysis [Glock]
     Full Idea: Under 'analysis' a minimum would include the Socratic quest for definitions, Descartes' search for simple natures, the empiricists' psychological resolution of complex ideas, and Kant's 'transcendental' analysis of our cognitive capacities.
     From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 6.1)
     A reaction: This has always struck me, and I find the narrow focus on modern logic a very distorted idea of the larger project. The aim, I think, is to understand by taking things apart, in the spirit of figuring out how a watch works.
11. Knowledge Aims / C. Knowing Reality / 3. Idealism / d. Absolute idealism
German and British idealism is not about individual ideas, but the intelligibility of reality [Glock]
     Full Idea: Neither German nor British Idealism reduced reality to episodes in the minds of individuals. Instsead, they insisted that reality is intelligible only because it is a manifestation of a divine spirit or rational principle.
     From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 5.2)
     A reaction: They standardly reject Berkeley. Such Idealism seems either to be the design argument for God's existence, or neo-Stoicism (in its claim that nature is rational). Why not just say that nature seems to be intelligible, and stop there?
13. Knowledge Criteria / A. Justification Problems / 2. Justification Challenges / c. Knowledge closure
Closure says if you know P, and also know P implies Q, then you must know Q [Dretske]
     Full Idea: Closure is the epistemological principle that if S knows that P is true and knows that P implies Q, then, evidentially speaking, this is enough for S to know that Q is true. Nothing more is needed.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.25)
     A reaction: [Dretske was the first to raise this issue] It is 'closure' because it applies to every case of Q, which is every implication of P that is known. The issue is whether we really do know all such Qs. Dretske doubts it. See his zebra case.
We needn't regret the implications of our regrets; regretting drinking too much implies the past is real [Dretske]
     Full Idea: One doesn't have to regret everything one knows to be implied by what one regrets. Tom regrets drinking three martinis, but doesn't regret what he knows to be implied by this - that he drank 'something', or that the past is real.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.28)
     A reaction: A nice case of analogy! He's right about regret. Perceptual and inferential knowledge have different grounds. To deny inferential knowledge seems to be a denial that modus ponens can be a justification. But MP gives truth, not knowledge.
Reasons for believing P may not transmit to its implication, Q [Dretske]
     Full Idea: Some reasons for believing P do not transmit to things, Q, known to be implied by P.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.29)
     A reaction: That seems true enough. I see someone limping, but infer that their leg is damaged. The only question is whether I should accept the inference. How can I accept that inference, but then back out of that knowledge?
Knowing by visual perception is not the same as knowing by implication [Dretske]
     Full Idea: A way of knowing there are cookies in the jar - visual perception - is not a way of knowing what one knows to be implied by this - that visual appearances are not misleading.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.29)
     A reaction: Why is the 'way of knowing' relevant? Isn't the only question that of whether implication of a truth is in infallible route to a truth (modus ponens)? If you know THAT it is true, then you must believe it, and implication is top quality justification. No?
The only way to preserve our homely truths is to abandon closure [Dretske]
     Full Idea: The only way to preserve knowledge of homely truths, the truths everyone takes themselves to know, is to abandon closure.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.32)
     A reaction: His point is that knowledge of homely truths seems to imply knowledge of the background facts needed to support them, which he takes to be an unreasonable requirement. I recommend pursuing contextualism, rather than abandoning closure.
P may imply Q, but evidence for P doesn't imply evidence for Q, so closure fails [Dretske]
     Full Idea: The evidence that gives me knowledge of P (there are cookies in the jar) can exist without evidence for knowing Q (they are not fake), despite my knowing that P implies Q. So closure fails.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.33)
     A reaction: His more famous example is the zebra. How can P imply Q if there is no evidence for Q? Maybe 'there are cookies in the jar' does not entail they are not fake, once you disambiguate what is being said?
We know past events by memory, but we don't know the past is real (an implication) by memory [Dretske]
     Full Idea: The reality of the past (a 'heavyweight implication') ...is something we know to be implied by things we remember, but it is not itself something we remember.
     From: Fred Dretske (The Case against Closure (and reply) [2005], p.35)
     A reaction: If I begin to doubt that the past is real, then I must necessarily begin to doubt my ordinary memories. This seems to be the modus tollens of knowledge closure. Doesn't that imply that the modus ponens was valid, and closure is correct?
18. Thought / D. Concepts / 2. Origin of Concepts / a. Origin of concepts
The concept 'red' is tied to what actually individuates red things [Peacocke]
     Full Idea: The possession conditions for the concept 'red' of the colour red are tied to those very conditions which individuate the colour red.
     From: Christopher Peacocke (Explaining the A Priori [2000], p.267), quoted by Carrie Jenkins - Grounding Concepts 2.5
     A reaction: Jenkins reports that he therefore argues that we can learn something about the word 'red' from thinking about the concept 'red', which is his new theory of the a priori. I find 'possession conditions' and 'individuation' to be very woolly concepts.
18. Thought / D. Concepts / 4. Structure of Concepts / h. Family resemblance
We might say that the family resemblance is just a consequence of meaning-as-use [Glock]
     Full Idea: Against Wittgenstein's family resemblance view one might evoke his own idea that the meaning of a word is its use, and that diversity of use entails diversity of meaning.
     From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 8.2)
     A reaction: Wittgenstein might just accept the point. Diversity of concepts reflects diversity of usage. But how do you distinguish 'football is a game' from 'oy, what's your game?'. How does usage distinguish metaphorical from literal (if it does)?
The variety of uses of 'game' may be that it has several meanings, and isn't a single concept [Glock]
     Full Idea: The proper conclusion to draw from the fact that we explain 'game' in a variety of different ways is that it is not a univocal term, but has different, albeit related, meanings.
     From: Hans-Johann Glock (What is Analytic Philosophy? [2008], 8.2)
     A reaction: [He cites Rundle 1990] Potter says Wittgenstein insisted that 'game' is a single concept. 'Game' certainly slides off into metaphor, as in 'are you playing games with me?'. The multivocal view would still meet family resemblance on a narrower range.
