22520 | You can't reason someone out of an irrational opinion [Swift] |
Full Idea: Reasoning will never make a man correct an ill opinion, which by reasoning he never acquired. | |
From: Jonathan Swift (Letters to a Young Clergyman [1720]) | |
A reaction: It would be hard to prove this, and someone full of irrational beliefs may have their rationality awakened by a sound argument. Nice remark, but too pessimistic. |
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. |
6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
