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). |
13416 | Mathematics must be based on axioms, which are true because they are axioms, not vice versa [Tait, by Parsons,C] |
Full Idea: The axiomatic conception of mathematics is the only viable one. ...But they are true because they are axioms, in contrast to the view advanced by Frege (to Hilbert) that to be a candidate for axiomhood a statement must be true. | |
From: report of William W. Tait (Intro to 'Provenance of Pure Reason' [2005], p.4) by Charles Parsons - Review of Tait 'Provenance of Pure Reason' §2 | |
A reaction: This looks like the classic twentieth century shift in the attitude to axioms. The Greek idea is that they must be self-evident truths, but the Tait-style view is that they are just the first steps in establishing a logical structure. I prefer the Greeks. |
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. |
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. |
5994 | Is the cosmos open or closed, mechanical or teleological, alive or inanimate, and created or eternal? [Robinson,TM, by PG] |
Full Idea: The four major disputes in classical cosmology were whether the cosmos is 'open' or 'closed', whether it is explained mechanistically or teleologically, whether it is alive or mere matter, and whether or not it has a beginning. | |
From: report of T.M. Robinson (Classical Cosmology (frags) [1997]) by PG - Db (ideas) | |
A reaction: A nice summary. The standard modern view is closed, mechanistic, inanimate and non-eternal. But philosophers can ask deeper questions than physicists, and I say we are entitled to speculate when the evidence runs out. |
