17651 | Without words or other symbols, we have no world [Goodman] |
Full Idea: We can have words without a world but no world without words or other symbols. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.3) | |
A reaction: Goodman seems to have a particularly extreme version of the commitment to philosophy as linguistic. Non-human animals have no world, it seems. |
17652 | Truth is irrelevant if no statements are involved [Goodman] |
Full Idea: Truth pertains solely to what is said ...For nonverbal versions and even for verbal versions without statements, truth is irrelevant. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.5) | |
A reaction: Goodman is a philosopher of language (like Dummett), but I am a philosopher of thought (like Evans). The test, for me, is whether truth is applicable to the thought of non-human animals. I take it to be obvious that it is applicable. |
17656 | Being primitive or prior always depends on a constructional system [Goodman] |
Full Idea: Nothing is primitive or derivationally prior to anything apart from a constructional system. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4c) | |
A reaction: Something may be primitive not just because we can't be bothered to analyse it any further, but because even God couldn't analyse it. Maybe. |
17661 | We don't recognise patterns - we invent them [Goodman] |
Full Idea: Recognising patterns is very much a matter of inventing or imposing them. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.7) | |
A reaction: I take this to be false. |
17659 | Reality is largely a matter of habit [Goodman] |
Full Idea: Reality in a world, like realism in a picture, is largely a matter of habit. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.6) | |
A reaction: I'm a robust realist, me, but I sort of see what he means. We become steeped in unspoken conventions about how we take our world to be, and filter out anything that conflicts with it. |
17657 | We build our world, and ignore anything that won't fit [Goodman] |
Full Idea: We dismiss as illusory or negligible what cannot be fitted into the architecture of the world we are building. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4d) | |
A reaction: I'm trying to think of an example of this, but can't. Maybe poor people are invisible to the rich? |
17654 | A world can be full of variety or not, depending on how we sort it [Goodman] |
Full Idea: A world may be unmanageably heterogeneous or unbearably monotonous according to how events are sorted into kinds. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4a) | |
A reaction: We might expect this from the man who invented 'grue', which allows you to classify things that change colour with things that don't. Could you describe a bird as 'might have been a fish', and classify it with fish? ('Projectible'?) |
17653 | Things can only be judged the 'same' by citing some respect of sameness [Goodman] |
Full Idea: Identification rests upon organization into entities and kinds. The response to the question 'Same or not the same?' must always be 'Same what?'. ...Identity or constancy in a world is identity with respect to what is within that world as organised. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4a) | |
A reaction: And the gist of his book is that 'organised' is done by us, not by the world. He seems to be committed to the full Geachean relative identity, rather than the mere Wigginsian relative individuation. An unfashionable view! |
2730 | Because 'gold is malleable' is necessary does not mean that it is analytic [Audi,R] |
Full Idea: Taking the proposition that gold is malleable to be necessary does not commit one to considering it analytic. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], IV p.116) |
2715 | Beliefs are based on perception, memory, introspection or reason [Audi,R] |
Full Idea: The four basic kinds of belief are rooted in perception, memory, introspective consciousness, and reason. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], Intr.p.7) |
2735 | Could you have a single belief on its own? [Audi,R] |
Full Idea: Could one have just a single belief? | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VII p.198) |
2736 | We can make certain of what we know, so knowing does not entail certainty [Audi,R] |
Full Idea: The possibility of making certain of what we already know suggests that knowing a proposition does not entail its being certain. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VIII p.220) |
2721 | If you gradually remove a book's sensory properties, what is left at the end? [Audi,R] |
Full Idea: If you imagine subtracting a book's sensory properties one by one, what is left of it? | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.42) |
2722 | Sense-data theory is indirect realism, but phenomenalism is direct irrealism [Audi,R] |
Full Idea: Where the sense-datum theory is an indirect realism, phenomenalism is a direct irrealism. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.43) |
2727 | Red and green being exclusive colours seems to be rationally graspable but not analytic [Audi,R] |
Full Idea: The proposition that nothing is red and green all over at once is not analytic, but it is rationally graspable, so it seems to be an a priori synthetic proposition. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], IV p.100) |
2728 | The concepts needed for a priori thought may come from experience [Audi,R] |
Full Idea: I may well need experience to acquire the concepts needed for knowledge of the a priori, such as the concept of a colour. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], IV p.103) |
2717 | How could I see a field and believe nothing regarding it? [Audi,R] |
Full Idea: How could I see a field and believe nothing regarding it? | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.20) |
2716 | To see something as a field, I obviously need the concept of a field [Audi,R] |
Full Idea: The propositional belief which portrays what I see in front of me AS a field requires my having a concept of one. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.17) | |
A reaction: To me this immediately invites the question of what a cow or horse experiences when they look at a familiar field. They know how to leave and enter it, and register its boundaries and qualities. Concepts? |
2720 | Sense-data (and the rival 'adverbial' theory) are to explain illusions and hallucinations [Audi,R] |
Full Idea: The sense-datum theory is mainly to explain hallucinations and illusions, though there might be other theories, such as the 'adverbial' theory. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.36) |
2719 | Sense data imply representative realism, possibly only representing primary qualities [Audi,R] |
Full Idea: A sense-datum theory might be called a representative realism because it conceives perception as a relation in which sense-data represent perceived external (hence real) objects to us. For Locke they were resemblances only of primary qualities. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.33) |
2718 | Perception is first simple, then objectual (with concepts) and then propositional [Audi,R] |
Full Idea: Simple perceiving gives rise to objectual perceiving (attaching concepts to the object), which gives rise to propositional perceiving. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], I p.23) |
2741 | The principles of justification have to be a priori [Audi,R] |
Full Idea: The crucial principles of justification are a priori. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], X p.311) |
2729 | Virtually all rationalists assert that we can have knowledge of synthetic a priori truths [Audi,R] |
Full Idea: Rationalists virtually always assert or imply that, in addition to knowledge of analytic truths, there is knowledge of synthetic a priori truths. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], IV p.105) |
2725 | To remember something is to know it [Audi,R] |
Full Idea: Remembering something is so entails knowing that it is so. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], II p.68) | |
A reaction: Clearly I can say I "remember" x, but be wrong. Presumably we then say that I didn't really remember, which requires success, like "I know". It is true (as with "know") that as soon as I say that the something is false, I can't claim to remember it. |
2724 | I might remember someone I can't recall or image, by recognising them on meeting [Audi,R] |
Full Idea: If I can neither recall nor image Jane I can still remember her, for on seeing her I might recognise her, and might remember, and even recall, our last meeting. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], II p.66) | |
A reaction: Hm. I can hardly claim to remember her if I have no concept of her, and don't recall our last meeting. If seeing her triggers recognition, I would say that I NOW remember her, but I didn't before. Memory is more conscious than Audi claims. |
2731 | Justification is either unanchored (infinite or circular), or anchored (in knowledge or non-knowledge) [Audi,R] |
Full Idea: There are four possible kinds of epistemic chain: infinite and unanchored, circular and unanchored, anchored in a belief which is not knowledge, and anchored in a belief which is bedrock knowledge. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VII p.183) | |
A reaction: About right, though I don't think 'chain' is the right word for what is proposed if justification is to be coherent. The justifications float like lilies in the pond of reason, and a Self (Monet?) seems needed to assess the picture |
2739 | Internalism about justification implies that there is a right to believe something [Audi,R] |
Full Idea: Internalists about justification tend to conceive of it as a matter of having a right to believe something. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VIII p.234) | |
A reaction: I'm an internalist, but I don't understand this, unless it refers to the social aspect of justification. Can I grant myself internal rights? I can justify my belief to other people. |
17660 | Discovery is often just finding a fit, like a jigsaw puzzle [Goodman] |
Full Idea: Discovery often amounts, as when I place a piece in a jigsaw puzzle, not to arrival at a proposition for declaration or defense, but to finding a fit. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.7) | |
A reaction: I find Goodman's views here pretty alien, but I like this bit. Coherence really rocks. |
2732 | Maths may be consistent with observations, but not coherent [Audi,R] |
Full Idea: That 7+5=12 and that carrots are nourishing are mutually consistent, but do not exhibit coherence. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VII p.192) | |
A reaction: This shows how difficult it would be to define 'coherent'. Is 'carrots are nourishing' coherent with 'fish are nourishing'? Is the battle of Hastings coherent with the battle of Waterloo? |
2733 | It is very hard to show how much coherence is needed for justification [Audi,R] |
Full Idea: It is very difficult to specify when an explanatory relation generates enough coherence to create justification. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VII p.193) | |
A reaction: I take coherence to be the key concept in epistemology, and quite impossible to define. This is why the 'space of reasons' is a useful concept. It is a courtroom, in which each case is different. |
2734 | A consistent madman could have a very coherent belief system [Audi,R] |
Full Idea: A schizophrenic who thinks he is Napoleon, if he has a completely consistent story with enough interlocking details, may have a belief system that is superbly coherent. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VII p.194) | |
A reaction: This is an exaggeration, but the fact is that one isolated lie is totally coherent, so coherence can only emerge when a system is large. Sense experience must be central to coherence. |
2738 | Consistent accurate prediction looks like knowledge without justified belief [Audi,R] |
Full Idea: If someone consistently prophesied the winners of horse races, it appears that this man knows who will win the races, but surely he does not have justified beliefs as to who will win? | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VIII p.229) | |
A reaction: This is where internalists and externalists (notably reliabilists) sharply part company. IF a reliable clairvoyant appeared, we would eventually accept them as a knower. But they DON'T appear, because knowledge needs justification! |
2740 | A reliability theory of knowledge seems to involve truth as correspondence [Audi,R] |
Full Idea: If one favours a reliability theory of knowledge (which is externalist) the correspondence theory of truth seems the most appropriate. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VIII p.243) | |
A reaction: Sounds right. Coherence implies some sort of internal assessment, whereas correspondence just needs to plugged into the facts. I like coherence justification and correspondence truth. |
2737 | 'Reliable' is a very imprecise term, and may even mean 'justified' [Audi,R] |
Full Idea: Reliabilism cannot specify how reliable a process must be before it grounds knowledge, and it cannot specify what is reliable in the first place. 'Reliable' may become circular, and may mean 'justified'. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], VIII p.225) | |
A reaction: The first time you ever read an instrument, or talk to a stranger, you have no indication of reliability. Circularity looks like a big problem. Knowledge must precede reliability? |
17658 | Users of digital thermometers recognise no temperatures in the gaps [Goodman] |
Full Idea: To use a digital thermometer with readings in tenths of a degree is to recognise no temperature as lying between 90 and 90.1 degrees. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4d) | |
A reaction: This appears to be nonsense, treating users of digital thermometers as if they were stupid. No one thinks temperatures go up and down in quantum leaps. We all know there is a gap between instrument and world. (Very American, I'm thinking!) |
17650 | We lack frames of reference to transform physics, biology and psychology into one another [Goodman] |
Full Idea: We have no neat frames of reference, no ready rules for transforming physics, biology and psychology into one another. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.2) |
17655 | Grue and green won't be in the same world, as that would block induction entirely [Goodman] |
Full Idea: Grue cannot be a relevant kind for induction in the same world as green, for that would preclude some of the decisions, right or wrong, that constitute inductive inference. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.4b) | |
A reaction: This may make 'grue' less mad than I thought it was. I always assume we are slicing the world as 'green, blue and grue'. I still say 'green' is a basic predicate of experience, but 'grue' is amenable to analysis. |
2726 | We can be ignorant about ourselves, for example, our desires and motives [Audi,R] |
Full Idea: We can have false beliefs, or some degree of ignorance, about our own mental lives. For example, about our own dispositions, such as not believing that we have a certain ignoble desire. | |
From: Robert Audi (Epistemology: contemporary introduction [1998], III p.83) | |
A reaction: This idea, that we don't know ourselves, has become a commonplace of recent philosophy, but I am unconvinced. Mostly we know only too well that we harbour a base desire, and we feel a creeping sense of shame. Total ignorance is very rare. |
16362 | An identity statement aims at getting the hearer to merge two mental files [Lockwood] |
Full Idea: The purpose of an identity statement is to get the hearer to merge these files or bodies of information into one. | |
From: Michael Lockwood (Identity and Reference [1971], p.209), quoted by François Recanati - Mental Files 4.1 | |
A reaction: Lockwood is a pioneer, in seeing 'Hesperus is Phosphorus' and 'Scott is the author of 'Waverley'' in terms of how the mind works. Mental files seem to me to explain a huge amount. Recanati proposes 'linking' rather than 'merging'. |
17649 | If the world is one it has many aspects, and if there are many worlds they will collect into one [Goodman] |
Full Idea: If there is but one world, it embraces a multiplicity of contrasting aspects; if there are many worlds, the collection of them all is one. One world may be taken as many, or many worlds taken as one; whether one or many depends on the way of taking. | |
From: Nelson Goodman (Ways of Worldmaking [1978], 1.2) | |
A reaction: He cites 'The Pluralistic Universe' by William James for this idea. The idea is that the distinction 'evaporates under analysis'. Parmenides seems to have thought that no features could be distinguished in the true One. |
