18405 | A 'teepee' argument has several mutually supporting planks to it [Cappelen/Dever] |
Full Idea: In a 'teepee' argument, a number of argumentative planks intersupport each other. No plank is sufficiently strong to establish the position, but each lends credibility to the others because there is the appearance of a unified phenomenon. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.5) | |
A reaction: To attack it, they say, you have to identify the separate planks of the argument. It is a moot point whether the teepee might be so imprecise that it is better described as 'coherence'. There is a background support, as well as the planks. |
13342 | Carnap defined consequence by contradiction, but this is unintuitive and changes with substitution [Tarski on Carnap] |
Full Idea: Carnap proposed to define consequence as 'sentence X follows from the sentences K iff the sentences K and the negation of X are contradictory', but 1) this is intuitively impossible, and 2) consequence would be changed by substituting objects. | |
From: comment on Rudolph Carnap (The Logical Syntax of Language [1934], p.88-) by Alfred Tarski - The Concept of Logical Consequence p.414 | |
A reaction: This seems to be the first step in the ongoing explicit discussion of the nature of logical consequence, which is now seen by many as the central concept of logic. Tarski brings his new tool of 'satisfaction' to bear. |
13251 | Each person is free to build their own logic, just by specifying a syntax [Carnap] |
Full Idea: In logic, there are no morals. Everyone is at liberty to build his own logic, i.e. his own form of language. All that is required is that he must state his methods clearly, and give syntactical rules instead of philosophical arguments. | |
From: Rudolph Carnap (The Logical Syntax of Language [1934], §17), quoted by JC Beall / G Restall - Logical Pluralism 7.3 | |
A reaction: This is understandable, but strikes me as close to daft relativism. If I specify a silly logic, I presume its silliness will be obvious. By what criteria? I say the world dictates the true logic, but this is a minority view. |
18422 | Prioprioception focuses on your body parts, not on your self, or indexicality [Cappelen/Dever] |
Full Idea: Proprioception is not focused single-mindedly on the self, but is focused on a number of objects - the component bodily parts that belong to the self. There is no obvious need for a concept of the self, or of indexicality. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 07.2) |
18425 | We can acquire self-knowledge with mirrors, not just with proprioception and introspection [Cappelen/Dever] |
Full Idea: Imagine a being that learns everything about itself by watching itself in mirrors, rather than by proprioception and introspection. Surely it can get wet in a storm, even though allegedly distinctive routes of self-knowledge are not available to it? | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 09.3) | |
A reaction: [compressed] |
18421 | Proprioception is only immune from error if you are certain that it represents the agent [Cappelen/Dever] |
Full Idea: The guarantee of immunity from error in prioprioception is only as strong as the guarantee that proprioception only ever represents the proprioceiving agent. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 07.1) | |
A reaction: This is part of an interesting and sustained attack on the idea that self-knowledge is immune from error. They are thinking of science-fictiony situations where I am wired up to experience your leg movement. My experiences usually track me, that's all. |
18419 | Folk Functionalism is a Ramsification of our folk psychology [Cappelen/Dever] |
Full Idea: According to Folk Functionalism, mental states are theoretically defined by Ramsifying on our folk-psychological theory. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 06.2) |
18404 | It is assumed that indexical content is needed to represent the perspective of perception [Cappelen/Dever] |
Full Idea: Because our perceptual states typically represent the world as seen from a perspective, it is sometimes thought that some distinctively indexical kind of content is needed to characterise those states. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.4) | |
A reaction: They are summarising this view precisely so that they can oppose it, and I think they are right. |
18426 | All information is objective, and purely indexical information is not much use [Cappelen/Dever] |
Full Idea: Fundamentally, all information is objective information. ...[176] What we want is fully portable information, and information that co-ordinates on the world, rather than on us, is best suited for the task. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: I agree entirely with their thesis. We just pick up information about ourselves, such as who and where we are, which is just like equivalent information about other people. It is isn't a special type of information. |
18427 | If some of our thought is tied to its context, it will be hard to communicate it [Cappelen/Dever] |
Full Idea: It is bad news if some of our contents are essentially tied to particular contexts. ...If information needs to be assessed relative to some ur-context, later recipients won't know what to do with it. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) |
18428 | You don't remember your house interior just from an experienced viewpoint [Cappelen/Dever] |
Full Idea: When you recall the look of the inside of your house ....where things are relative to one another is what persists in memory, not where they were relative to you when seen. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: This seems to be a very telling example, though you could postulate some system which converts perspectival input into objective information. But why bother? We seek objective information, not perspectives. |
18429 | Our beliefs and desires are not organised around ourselves, but around the world [Cappelen/Dever] |
Full Idea: Our view on the world is not primarily a view from a perspective. Our beliefs and desires are not organized around us. They are instead organized around the world itself. Our view is a view from everywhere. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 10) | |
A reaction: Slipping in the claim that our desires are also organised around the world is not quite as persuasive as the claim about beliefs. If you want to draw a freehand straight line, focus on the far end of it. The world will guide your hand. |
18407 | Indexicality is not significantly connected to agency [Cappelen/Dever] |
Full Idea: There are no interesting or distinctive explanatory connections between indexicality and agency. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.8) |
18413 | Fregeans can't agree on what 'senses' are [Cappelen/Dever] |
Full Idea: There is little agreement among Fregeans about what senses are. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 04.5) | |
A reaction: I don't take this to be sufficient grounds for dismissing Fregean senses. When we look into the workings of the linguistic mind, there seems little prospect of clarity or agreement. |
18417 | Possible worlds accounts of content are notoriously coarse-grained [Cappelen/Dever] |
Full Idea: Possible worlds accounts of content are notoriously coarse-grained. They fail to distinguish between logical or mathematical truths, ..between metaphysical equivalences, ..between coreferentials, ..and between indexicals and non-indexicals. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 05.5) | |
A reaction: [A nice summary, very compressed] |
18408 | Indexicals are just non-constant in meaning, and don't involve any special concepts [Cappelen/Dever] |
Full Idea: Once the non-constant characters of expressions has been characterised, there is no further need for additional devices like 'first-person concepts' or 'demonstrative concepts'. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.7) | |
A reaction: This seems to me to be a wonderfully liberating attack on this issue. There is a kind of creepy mysticism that has been allowed to accrue around indexicals, and it's nonsense. |
18414 | Fregeans say 'I' differs in reference, so it must also differ in sense [Cappelen/Dever] |
Full Idea: Fregeans tend to treat as a fundamental tenet that sense determines reference; same sense, same reference. From that it follow trivially that indexicals don't have the same sense: different uses of 'I' have different referents, so sense must differ. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 04.6) | |
A reaction: Interesting. Since it seems implausible that 'I' is profoundly different when two people use it, this seems to be a strong argument against Frege's distinction. But I rather like Frege's distinction, while being sceptical about 'I', so I'm baffled.... |
18423 | All indexicals can be expressed non-indexically [Cappelen/Dever] |
Full Idea: Whatever can be expressed indexically could be expressed by non-indexical means. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 08.1) | |
A reaction: This is the best summary of the thesis of their book. Indexicality in non-essential. |
18406 | The basic Kaplan view is that there is truth-conditional content, and contextual character [Cappelen/Dever] |
Full Idea: In what we label 'Basic Kaplanianism', each of the sentences 'Smith is happy' and 'I am happy', as uttered by Smith, has two levels of meaning. The 'content' is a truth-conditional representation. The 'character' is a function from contexts to contents. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 01.6) | |
A reaction: They give this as a minimal and plausible account of the situation, without reading huge significance into the indexical. I'm inclined to see the situation in terms of the underlying proposition containing both ingredients. |
18411 | It is proposed that a huge range of linguistic items are context-sensitive [Cappelen/Dever] |
Full Idea: An enormous amount has been written about whether 'all', 'know', 'might', 'delicious', 'good', 'if, then', 'and', 'red', 'just', 'justified', 'probable', 'local', 'ready', and 'left-right' are context-sensitive. | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 02.3) | |
A reaction: The clearest way to approach these things is ask what the (informal) domain of quantification is for that particular context. The domain can shift in the course of a sentence. |
18420 | We deny that action involves some special class of beliefs [Cappelen/Dever] |
Full Idea: Maybe there is a class of beliefs that plays a special role in the explanation of action. We have argued against the existence of such a class (or at least any interesting such class). | |
From: Cappelen,H/Dever,Josh (The Inessential Indexical [2013], 06.2) | |
A reaction: The main class which has been proposed is the one that involves indexical beliefs. I agree with this idea. |
9111 | God is not wise, but more-than-wise; God is not good, but more-than-good [William of Ockham] |
Full Idea: God is not wise, but more-than-wise; God is not good, but more-than-good. | |
From: William of Ockham (Reportatio [1330], III Q viii) | |
A reaction: [He is quoting 'Damascene'] I quote this for interest, but I very much doubt whether Damascene or William knew what it meant, and I certainly don't. There seems to have been a politically correct desire to invent super-powers for God. |
9112 | We could never form a concept of God's wisdom if we couldn't abstract it from creatures [William of Ockham] |
Full Idea: What we abstract is said to belong to perfection in so far as it can be predicated of God and can stand for Him. For if such a concept could not be abstracted from a creature, then in this life we could not arrive at a cognition of God's wisdom. | |
From: William of Ockham (Reportatio [1330], III Q viii) | |
A reaction: This seems to be the germ of an important argument. Without the ability to abstract from what is experienced, we would not be able to apply general concepts to things which are beyond experience. It is a key idea for empiricism. |
