8877 | We can't attain a coherent system by lopping off any beliefs that won't fit [Sosa] |
Full Idea: Coherence involves the logical, explanatory and probabilistic relations among one's beliefs, but it could not do to attain a tightly iterrelated system by lopping off whatever beliefs refuse to fit. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.4) | |
A reaction: This is clearly right, so the coherentist has to distinguish between lopping off a belief because it is inconvenient (fundamentalists rejecting textual contradictions), and lopping it off because it is wrong (chemists rejecting phlogiston). |
8884 | The phenomenal concept of an eleven-dot pattern does not include the concept of eleven [Sosa] |
Full Idea: You could detect the absence of an eleven-dot pattern without having counted the dots, so your phenomenal concept of that array is not an arithmetical concept, and its content will not yield that its dots do indeed number eleven. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 7.3) | |
A reaction: Sosa is discussing foundational epistemology, but this draws attention to the gulf that has to be leaped by structuralists. If eleven is not derived from the pattern, where does it come from? Presumably two eleven-dotters are needed, to map them. |
1630 | We can only see an alien language in terms of our own thought structures (e.g. physical/abstract) [Quine] |
Full Idea: We are prone to talk about physical and abstract objects. It is hard to know how else to talk, because we are bound to adapt any alien pattern to our own in the very process of understanding or translating the alien sentences. | |
From: Willard Quine (Speaking of Objects [1960], pt.I,p.1) | |
A reaction: It is fine for mathematicians (or economists) to refer to their subject matter as 'objects', but ontologists really need to be more careful. Some very silly theories can otherwise result. |
5747 | "No entity without identity" - our ontology must contain items with settled identity conditions [Quine, by Melia] |
Full Idea: Quine's well-known slogan "no entity without identity" means that no object should be admitted into our ontology unless its identity conditions, the conditions that say which object it is, have been settled. | |
From: report of Willard Quine (Speaking of Objects [1960]) by Joseph Melia - Modality Ch.4 | |
A reaction: This invites science fiction scenarios, where we admit the existence of something before we have a clue what it is (whether it is physical, hallucination, divine..). Quine's slogan seems attractive but optimistic. How 'settled'? |
7925 | There is no proper identity concept for properties, and it is hard to distinguish one from two [Quine] |
Full Idea: The lack of a proper identity concept for attributes (properties) is a lack that philosophers feel impelled to supply; for, what sense is there in saying there are attributes when there is no sense in saying when there is one attribute and when two? | |
From: Willard Quine (Speaking of Objects [1960], IV) | |
A reaction: This strikes me as being a really crucial question. There is a mistaken tendency to take any possible linguistic predicate as implying a natural property. I sympathise with the sceptics here (see Ideas 4029, 3906, 3322). How to individuate properties? |
13387 | Our conceptual scheme becomes more powerful when we posit abstract objects [Quine] |
Full Idea: There is no denying the access of power that accrues to our conceptual scheme through the positing of abstract objects. | |
From: Willard Quine (Speaking of Objects [1960], §5) | |
A reaction: This seems right, both in its use of the word 'posit', and in its general pragmatic claim. So why? If they enable us to grapple with the world better, it must be because of their power of generalisation. They are nets thrown over chunks of reality. |
8277 | I prefer 'no object without identity' to Quine's 'no entity without identity' [Lowe on Quine] |
Full Idea: To adapt Quine's famous slogan ('no entity without identity'), I prefer to say 'no object without identity'. | |
From: comment on Willard Quine (Speaking of Objects [1960], p.52) by E.J. Lowe - The Possibility of Metaphysics 7.1 | |
A reaction: Quine was trying to make us all more scientific, but Lowe is closer to common sense. The sky is an entity, most of us would say, but with very shaky identity-conditions. A wave of the sea is a good example. |
6019 | If someone squashed a horse to make a dog, something new would now exist [Mnesarchus] |
Full Idea: If, for the sake of argument, someone were to mould a horse, squash it, then make a dog, it would be reasonable for us on seeing this to say that this previously did not exist but now does exist. | |
From: Mnesarchus (fragments/reports [c.120 BCE]), quoted by John Stobaeus - Anthology 179.11 | |
A reaction: Locke would say it is new, because the substance is the same, but a new life now exists. A sword could cease to exist and become a new ploughshare, I would think. Apply this to the Ship of Theseus. Is form more important than substance? |
8878 | It is acceptable to say a supermarket door 'knows' someone is approaching [Sosa] |
Full Idea: I am quite flexible on epistemic terminology, and am even willing to grant that a supermarket door can 'know' that someone is approaching. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.6) | |
A reaction: I take this amazing admission to be a hallmark of externalism. Sosa must extend this to thermostats. So flowers know the sun has come out. This is knowledge without belief. Could the door ever be 'wrong'? |
8880 | In reducing arithmetic to self-evident logic, logicism is in sympathy with rationalism [Sosa] |
Full Idea: In trying to reduce arithmetic to self-evident logical axioms, logicism is in sympathy with rationalism. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.7) | |
A reaction: I have heard Frege called "the greatest of all rationalist philosophers". However, the apparent reduction of arithmetic to analytic truths played into the hands of logical positivists, who could then marginalise arithmetic. |
8881 | Most of our knowledge has insufficient sensory support [Sosa] |
Full Idea: Almost nothing that one knows of history or geography or science has adequate sensory support, present or even recalled. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.7) | |
A reaction: This seems a bit glib, and may be false. The main issue to which this refers is, of course, induction, which (almost by definition) is a supposedly empirical process which goes beyond the empirical evidence. |
8882 | Perception may involve thin indexical concepts, or thicker perceptual concepts [Sosa] |
Full Idea: There is a difference between having just an indexical concept which one can apply to a perceptual characteristic (just saying 'this is thus'), and having a thicker perceptual concept of that characteristic. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 7.2) | |
A reaction: Both of these, of course, would precede any categorial concepts that enabled one to identify the characteristic or the object. This is a ladder foundationalists must climb if they are to reach the cellar of basic beliefs. |
8883 | Do beliefs only become foundationally justified if we fully attend to features of our experience? [Sosa] |
Full Idea: Are foundationally justified beliefs perhaps those that result from attending to our experience and to features of it or in it? | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 7.3) | |
A reaction: A promising suggestion. I do think our ideas acquire a different epistmological status once we have given them our full attention, though is that merely full consciousness, or full thoughtful evaluation? The latter I take to be what matters. Cf Idea 2414. |
8885 | Some features of a thought are known directly, but others must be inferred [Sosa] |
Full Idea: Some intrinsic features of our thoughts are attributable to them directly, or foundationally, while others are attributable only based on counting or inference. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 7.5) | |
A reaction: In practice the brain combines the two at a speed which makes the distinction impossible. I'll show you ten dot-patterns: you pick out the sixer. The foundationalist problem is that only those drained of meaning could be foundational. |
8876 | Much propositional knowledge cannot be formulated, as in recognising a face [Sosa] |
Full Idea: Much of our propositional knowledge is not easily formulable, as when a witness looking at a police lineup may know what the culprit's face looks like. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.1) | |
A reaction: This is actually a very helpful defence of foundationalism, because it shows that we will accept perceptual experiences as knowledge when they are not expressed as explicit propositions. Davidson (Idea 8801), for example, must deal with this difficulty. |
8879 | Fully comprehensive beliefs may not be knowledge [Sosa] |
Full Idea: One's beliefs can be comprehensively coherent without amounting to knowledge. | |
From: Ernest Sosa (Beyond internal Foundations to external Virtues [2003], 6.6) | |
A reaction: Beliefs that are fully foundational or reliably sourced may also fail to be knowledge. I take it that any epistemological theory must be fallibilist (Idea 6898). Rational coherentism will clearly be sensitive to error. |
1631 | You could know the complete behavioural conditions for a foreign language, and still not know their beliefs [Quine] |
Full Idea: We could know the necessary and sufficient stimulatory conditions of every possible act of utterance, in a foreign language, and still not know how to determine what objects the speakers of that language believe in. | |
From: Willard Quine (Speaking of Objects [1960], pt.III,p.11) | |
A reaction: I just don't believe this, because the same scepticism then creeps into discussions of native speakers of a single language, and all communcation is blighted - which is nonsense. |
1632 | Translation of our remote past or language could be as problematic as alien languages [Quine] |
Full Idea: Translation of our remote past or future discourse into the terms we now know could be about as tenuous and arbitrary a projection as translation of a heathen language was seen to be. | |
From: Willard Quine (Speaking of Objects [1960], pt.V,p.25) | |
A reaction: Is he seriously saying that we can't understand Shakespeare, because holism implies that we would have to be Elizabethans? So scholarship is in vain? Is yesterday the 'past'? |
