18810 | Aristotle's proofs give understanding, so it can't be otherwise, so consequence is necessary [Smiley, by Rumfitt] |
Full Idea: The ingredient of necessity [in Aristotle's account of consequence] is required by his demand that proof should produce 'understanding' [episteme], coupled with his claim that understanding something involves seeing that it cannot be otherwise. | |
From: report of Timothy Smiley (Conceptions of Consequence [1998], p.599) by Ian Rumfitt - The Boundary Stones of Thought 3.2 | |
A reaction: An intriguing reverse of the normal order. Not 'necessity in logic delivers understanding', but 'reaching understanding shows the logic was necessary'. |
8808 | Involuntary beliefs can still be evaluated [Feldman/Conee] |
Full Idea: Examples confirm that beliefs may be both involuntary and subject to epistemic evaluation. | |
From: R Feldman / E Conee (Evidentialism [1985], II) | |
A reaction: This is an extremely important point, which summarises the situation with beliefs that arise from (apparent) immediate perception. A belief cannot possibly be knowledge if it has been triggered, but no effort was made to evaluate it. |
8807 | Evidentialism is the view that justification is determined by the quality of the evidence [Feldman/Conee] |
Full Idea: What we call 'evidentialism' is the view that the epistemic justification of a belief is determined by the quality of the believer's evidence for the belief. | |
From: R Feldman / E Conee (Evidentialism [1985], I) | |
A reaction: The immediate question is whether the believer knows the quality of their evidence. A detective might not recognise the crucial clue (like the dog not barking). The definition of 'quality' had better not turn out to be circular. Forgotten evidence? |
8809 | Beliefs should fit evidence, and if you ought to believe it, then you are justified [Feldman/Conee] |
Full Idea: One epistemically ought to have the doxastic attitudes that fit one's evidence. Being epistemically obligatory is equivalent to being epistemically justified. | |
From: R Feldman / E Conee (Evidentialism [1985], III) | |
A reaction: It is normal for someone to refuse to accept something, when another person believes the evidence is overwhelming. Evaluation of evidence must include an assessment of what other evidence might turn up. |
8810 | If someone rejects good criticism through arrogance, that is irrelevant to whether they have knowledge [Feldman/Conee] |
Full Idea: If an arrogant young physicist refuses to recognise valid criticisms from a senior colleague, his or her character has nothing to do with the epistemic status of their belief in the theory. | |
From: R Feldman / E Conee (Evidentialism [1985], III) | |
A reaction: This rejects the idea that epistemic justification is essentially a matter of virtues and vices of character. That view is a version of reliabilism, and hence of externalism. I agree with the criticism, but epistemic virtues are still significant. |
3158 | Theories of intentionality presuppose rationality, so can't explain it [Dennett] |
Full Idea: Intentional theory is vacuous as psychology because it presupposes and does not explain rationality or intelligence. | |
From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.15?) | |
A reaction: Virtually every philosophical theory seems to founder because it presupposes something like the thing it is meant to explain. I agree that 'intentionality' is a slightly airy concept that would probably reduce to something better. |
3159 | Beliefs and desires aren't real; they are prediction techniques [Dennett] |
Full Idea: Intentional systems don't really have beliefs and desires, but one can explain and predict their behaviour by ascribing beliefs and desires to them. This strategy is pragmatic, not right or wrong. | |
From: Daniel C. Dennett (Brainstorms:Essays on Mind and Psychology [1978], p.7?) | |
A reaction: If the ascription of beliefs and desires explains behaviour, then that is good grounds for thinking they might be real features of the brain, and even if that is not so, they are real enough as abstractions from brain events, like the 'economic climate'. |
