23449 | Interpreting a text is representing it as making sense [Morris,M] |
Full Idea: Interpreting a text is a matter of making sense of it. And to make sense of a text is to represent it as making sense. | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], Intro.2) | |
A reaction: 'Making sense' is obviously not a very precise or determinate concept. It is probably better to say that the process is 'trying' to make sense of the text, because most texts don't totally make sense. |
23484 | Bipolarity adds to Bivalence the capacity for both truth values [Morris,M] |
Full Idea: According to the Principle of Bipolarity, every meaningful sentence must be capable both of being true and of being false. It is not enough merely that every sentence must be either true or false (which is Bivalence). | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], 3D) | |
A reaction: It is said that early Wittgenstein endorses this. That is, in addition to being true, the sentence must be capable of falsehood (and vice versa). This seems to be flirting with the verification principle. I presume it is 'affirmative' sentences. |
23494 | Conjunctive and disjunctive quantifiers are too specific, and are confined to the finite [Morris,M] |
Full Idea: There are two problems with defining the quantifiers in terms of conjunction and disjunction. The general statements are unspecific, and do not say which things have the properties, and also they can't range over infinite objects. | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], 5C) | |
A reaction: That is, the universal quantifier is lots of ands, and the existential is lots of ors. If there only existed finite objects, then naming them all would be universal, and the infinite wouldn't be needed. |
23460 | To count, we must distinguish things, and have a series with successors in it [Morris,M] |
Full Idea: Distinguishing between things is not enough for counting. …We need the crucial extra notion of a successor in a series of a certain kind. | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], Intro) | |
A reaction: This is the thinking that led to the Dedekind-Peano axioms for arithmetic. E.g. each series member can only have one successor. There is an unformalisable assumption that the series can then be applied to the things. |
23451 | Counting needs to distinguish things, and also needs the concept of a successor in a series [Morris,M] |
Full Idea: Just distinguishing things is not enough for counting (and hence arithmetic). We need the crucial extra notion of the successor in a series of some kind. | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], Intro.5) | |
A reaction: This is a step towards the Peano Axioms of arithmetic. The successors could be fingers and toes, taken in a conventional order, and matched one-to-one to the objects. 'My right big toe of cows' means 16 cows (but non-verbally). |
23452 | Discriminating things for counting implies concepts of identity and distinctness [Morris,M] |
Full Idea: The discrimination of things for counting needs to bring with it the notion of identity (and, correlatively, distinctness). | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], Intro.5) | |
A reaction: Morris is exploring how practices like counting might reveal necessary truths about the world. |
14082 | No sortal could ever exactly pin down which set of particles count as this 'cup' [Schaffer,J] |
Full Idea: Many decent candidates could the referent of this 'cup', differing over whether outlying particles are parts. No further sortal I could invoke will be selective enough to rule out all but one referent for it. | |
From: Jonathan Schaffer (Deflationary Metaontology of Thomasson [2009], 3.1 n8) | |
A reaction: I never had much faith in sortals for establishing individual identity, so this point comes as no surprise. The implication is strongly realist - that the cup has an identity which is permanently beyond our capacity to specify it. |
14081 | Identities can be true despite indeterminate reference, if true under all interpretations [Schaffer,J] |
Full Idea: There can be determinately true identity claims despite indeterminate reference of the terms flanking the identity sign; these will be identity claims true under all admissible interpretations of the flanking terms. | |
From: Jonathan Schaffer (Deflationary Metaontology of Thomasson [2009], 3.1) | |
A reaction: In informal contexts there might be problems with the notion of what is 'admissible'. Is 'my least favourite physical object' admissible? |
19558 | Our own intuitions about whether we know tend to vacillate [Cohen,S] |
Full Idea: One robust feature of our intuitions about whether we know things is that they tend to vacillate. | |
From: Stewart Cohen (Contextualism Defended (and reply) [2005], 1) | |
A reaction: This strikes me as important. If we were tacit invariantists (Idea 19557) we should be able to ask ourselves whether we 'really and truly' know various things, but we can't decide. I know lots about Nietzsche in a pub, and very little in a university. |
19561 | We shouldn't jump too quickly to a contextualist account of claims to know [Cohen,S] |
Full Idea: Maybe contextualists are too quick to appeal to our conflicting intuitions regarding knowledge. | |
From: Stewart Cohen (Contextualism Defended (and reply) [2005], 1) | |
A reaction: An important point (from Earl Conee). I thoroughly approve of contextualism, but the whole status of whether a witness or a teacher knows what they are talking about is in danger of collapsing into relativism. This is what peer review is all about. |
19563 | The context sensitivity of knowledge derives from its justification [Cohen,S] |
Full Idea: On my own view, the context sensivity of knowledge is inherited from one of its components, i.e. justification. | |
From: Stewart Cohen (Contextualism Defended (and reply) [2005], 1) | |
A reaction: That sounds right, and it reinforces the idea that 'justification' is a more important epistemological concept than 'knowledge'. 'Am I justified in believing p?' Answer: 'it depends how well you have researched it'. |
19560 | Contextualism is good because it allows knowledge, but bad because 'knowing' is less valued [Cohen,S] |
Full Idea: Contextualism is a 'good news, bad news' theory. The good news is that we have lots of knowledge and many surfaces are 'flat'; the bad news is that knowledge and flatness are not all they were cracked up to be. | |
From: Stewart Cohen (Contextualism Defended (and reply) [2005], 3) | |
A reaction: That is exactly my position. I lost all interest in whether someone precisely 'knows' or 'does not know' something a long time ago (even in scientific or forensic contexts). In the case of flatness the case is even more obvious. |
19559 | Contextualists slightly concede scepticism, but only in extremely strict contexts [Cohen,S] |
Full Idea: Contextualism concedes that there is some truth to skepticism, but contains the damage by holding that skeptical claims are true only relative to atypically strict contexts. | |
From: Stewart Cohen (Contextualism Defended (and reply) [2005], 1) | |
A reaction: My attitude to scepticism is that everything we ever affirm should have a footnote saying '...but you never know...', and it should then be ignored. In the strictest context everything is doubted simultaneously (including language), and that is paralysis. |
23491 | There must exist a general form of propositions, which are predictabe. It is: such and such is the case [Morris,M] |
Full Idea: The existence of a general propositional form is proved by the fact that there cannot be a proposition whose form could not have been foreseen (i.e. constructed). The general form of the proposition is: Such and such is the case. | |
From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], 4.5) | |
A reaction: [last bit in Ogden translation] LW eventually expresses this symbolically. We could just say a proposition is an assertion. This strikes as either a rather empty claim, or an unfounded one. |
