| 21552 | Common speech is vague; its vocabulary and syntax must be modified, for precision [Russell] |
| Full Idea: I am persuaded that common speech is full of vagueness and inaccuracy, and that any attempt to be precise and accurate requires modification of common speech both as regards vocabulary and as regards syntax. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.123) | |
| A reaction: It is interesting that he cites the syntax of ordinary language, as well as the vocabulary. The implication is that vagueness can also be a feature of syntax (and hence his pursuit of logical form), which is not normally mentioned |
| 21551 | Empirical words need ostensive definition, which makes them egocentric [Russell] |
| Full Idea: The meanings of all empirical words depend ultimately upon ostensive definitions, ostensive definitions depend upon experience, and that experience is egocentric. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.122) | |
| A reaction: He seems to imply that this makes them partly subjective, but I don't see why an objective consensus can't be reached when making an ostensive definition. We just need to clearly agree what 'that' refers to. |
| 19702 | We can't normally say that we know something 'but it might be false' [Dougherty] |
| Full Idea: It will ordinarily be conversationally inappropriate to say 'I know that p, but p might be false' even if it is true, since this would mislead an interlocutor to infer that that possibility was an epistemically significant one. | |
| From: Trent Dougherty (Fallibilism [2011], 'Epistemic') | |
| A reaction: This seems to imply hypocrisy when a fallibilist philosopher claims (in non-philosophical company) to know something. Fair enough. Philosophers are in a permanent state of hypocrisy about what they are really thinking. That's the fun of it. |
| 19701 | Fallibilism is consistent with dogmatism or scepticism, and is not alternative to them [Dougherty] |
| Full Idea: There has been a tendency to treat fallibilism as an alternative to either dogmatism or scepticism. ...But it is much better to think of fallibilism as consistent with either dogmatism or skepticism. | |
| From: Trent Dougherty (Fallibilism [2011], 'Closure') | |
| A reaction: It seems perfectly reasonably to describe oneself as a 'fallibilist dogmatist' (perhaps from the Pope?), or a 'fallibilist sceptic' (perhaps from Peter Unger?), so this idea sounds correct. |
| 19700 | It is best to see the fallibility in the reasons, rather than in the agents or the knowledge [Dougherty] |
| Full Idea: It seems best to take fallible reasons as the basic notion of fallibilism. So fallible knowers are agents who know what they know on the basis of fallible reasons. Fallible knowledge will be knowledge on basis of fallible reasons. | |
| From: Trent Dougherty (Fallibilism [2011], 'Cognates') | |
| A reaction: This is because an ideal knower would be compelled by the evidence, so if fallibilism is universal it must reside in the evidence and not in the knower (bottom p.131). |
| 21550 | Science reduces indexicals to a minimum, but they can never be eliminated from empirical matters [Russell] |
| Full Idea: It is of the essence of a scientific account of the world to reduce to a minimum the egocentric element in assertion, but success in this attempt is a matter of degree, and is never complete where empirical matter is concerned. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.121) | |
| A reaction: He cites ostensive definitions. The key issue is whether they can be wholly eliminated when we try to be objective. Russell here endorses Perry's claim that they never go away. Personally I just think that (if so) we should try harder. |
| 7861 | Libet says the processes initiated in the cortex can still be consciously changed [Libet, by Papineau] |
| Full Idea: Libet himself points out that the conscious decisions still have the power to 'endorse' or 'cancel', so to speak, the processes initiated by the earlier cortical activity: no action will result if the action's execution is consciously countermanded. | |
| From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by David Papineau - Thinking about Consciousness 1.4 | |
| A reaction: This is why Libet's findings do not imply 'epiphenomenalism'. It seems that part of a decisive action is non-conscious, undermining the all-or-nothing view of consciousness. Searle tries to smuggle in free will at this point (Idea 3817). |
| 6660 | Libet found conscious choice 0.2 secs before movement, well after unconscious 'readiness potential' [Libet, by Lowe] |
| Full Idea: Libet found that a subject's conscious choice to move was about a fifth of a second before movement, and thus later than the onset of the brain's so-called 'readiness potential', which seems to imply that unconscious processes initiates action. | |
| From: report of Benjamin Libet (Unconscious Cerebral Initiative [1985]) by E.J. Lowe - Introduction to the Philosophy of Mind Ch.9 | |
| A reaction: Of great interest to philosophers! It seems to make conscious choices epiphenomenal. The key move, I think, is to give up the idea of consciousness as being all-or-nothing. My actions are still initiated by 'me', but 'me' shades off into unconsciousness. |
