8800 | If you would deny a truth if you know the full evidence, then knowledge has social aspects [Harman, by Sosa] |
Full Idea: If one reads of a genuine assassination, but then fails to read the reports next day which untruthfully deny the event, one probably does not know of the event. But we must conclude that knowledge has a further 'social aspect'. | |
From: report of Gilbert Harman (Induction [1970], §IV) by Ernest Sosa - The Raft and the Pyramid Appx | |
A reaction: I doubt if this is enough to support an externalist account of defeasibility. Wise people don't 'know' of an event after one report. For 24 hours the Royalists thought they had won Marston Moor! You know he's dead when you see the Zapruder film. |
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'. |
4677 | If suicide is wrong because only God disposes of our lives, it must also be wrong to save lives [Hume] |
Full Idea: Were the disposal of human life so much the peculiar province of the Almighty that it were an encroachment on His right, for men to dispose of their own lives; it would be equally criminal to act for the preservation of life as for its destruction. | |
From: David Hume (On suicide [1775]), quoted by Jonathan Glover - Causing Death and Saving Lives §13 | |
A reaction: A characteristically wicked and neat point. Maybe we can intervene in the environment (diverting a falling stone), but not directly in a life? Life is sacred, but stones are not? |
