| 6417 | In 1921 Russell abandoned sense-data, and the gap between sensation and object [Russell, by Grayling] |
| Full Idea: In 'The Analysis of Mind' Russell gave up talk of 'sense-data', and ceased to distinguish between the act of sensing and what is sensed. | |
| From: report of Bertrand Russell (The Analysis of Mind [1921]) by A.C. Grayling - Russell Ch.2 | |
| A reaction: This seems to lead towards the modern 'adverbial' account of sensing, where I don't sense 'data', but where qualia (such as redness) are our particular mode of directly perceiving objects, where insects might directly perceive them in a different mode. |
| 6474 | Seeing is not in itself knowledge, but is separate from what is seen, such as a patch of colour [Russell] |
| Full Idea: Undeniably, knowledge comes through seeing, but it is a mistake to regard the mere seeing itself as knowledge; if we are so to regard it, we must distinguish the seeing from what is seen; a patch of colour is one thing, and our seeing it is another. | |
| From: Bertrand Russell (The Analysis of Mind [1921], Lec. VIII) | |
| A reaction: This is Russell's 1921 explanation of why he adopted sense-data (but he rejects them later in this paragraph). This gives a simplistic impression of what he intended, which has three components: the object, the 'sensibile', and the sense-datum. |
| 6476 | We cannot assume that the subject actually exists, so we cannot distinguish sensations from sense-data [Russell] |
| Full Idea: If we are to avoid a perfectly gratuitous assumption, we must dispense with the subject as one of the actual ingredients of the world; but when we do this, the possibility of distinguishing the sensation from the sense-datum vanishes. | |
| From: Bertrand Russell (The Analysis of Mind [1921], Lec. VIII) | |
| A reaction: This is the reason why Russell himself rejected sense-data. It is more normal, I think, to reject them simply as being superfluous. If the subject can simply perceive the sense-data, why can't they just perceive the object more directly? |
| 7628 | Broad rejects the inferential component of the representative theory [Broad, by Maund] |
| Full Idea: Broad, one of the most important modern defenders of the representative theory of perception, explicitly rejects the inferential component of the theory. | |
| From: report of C.D. Broad (Mind and Its Place in Nature [1925]) by Barry Maund - Perception Ch.1 | |
| A reaction: Since the supposed inferences happen much too quickly to be conscious, it is hard to see how we could distinguish an inference from an interpretation mechanism. Personally I interpret things long before the question of truth arises. |
| 2792 | It is possible the world came into existence five minutes ago, complete with false memories [Russell] |
| Full Idea: There is no logical impossibility in the hypothesis that the world sprang into being five minutes ago, exactly as it then was, with a population that "remembered" a wholly unreal past. | |
| From: Bertrand Russell (The Analysis of Mind [1921], p.159) | |
| A reaction: One of the great sceptical arguments! At a stroke it undermines forever any dreams that memories are totally certain. This is an extra scepticism, which arises if you decide that current experience IS totally certain. |
| 22326 | Knowledge needs more than a sensitive response; the response must also be appropriate [Russell] |
| Full Idea: Accuracy of response to stimulus does not alone show knowledge, but must be reinforced by appropriateness, i.e. suitability of realising one's purpose. | |
| From: Bertrand Russell (The Analysis of Mind [1921], p.261), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 66 'Rel' | |
| A reaction: The aim of 'realising one's purpose' puts a very pragmatist spin on this. The point is a good one, and seems to apply particularly to Nozick's accurate 'tracking' account of knowledge. |
| 6475 | In perception, the self is just a logical fiction demanded by grammar [Russell] |
| Full Idea: In perception, the idea of the subject appears to be a logical fiction, like mathematical points and instants; it is introduced, not because observation reveals it, but because it is linguistically convenient and apparently demanded by grammar. | |
| From: Bertrand Russell (The Analysis of Mind [1921], Lec. VIII) | |
| A reaction: In 1912, Russell had felt that both the Cogito, and the experience of meta-thought, had confirmed the existence of a non-permanent ego, but here he offers a Humean rejection. His notion of a 'logical fiction' is behaviouristic. I believe in the Self. |
| 6853 | Consequentialism wrongly assumes a clear line between an act and its consequences [Crisp,R] |
| Full Idea: What is wrong with consequentialism is that it assumes that there is agreement about when an act ends and when its consequences begin. | |
| From: Roger Crisp (Interview with Baggini and Stangroom [2001], p.31) | |
| A reaction: I certainly agree that this is a mistake in consequentialism, which has a crude idea of what an action is, though I am not convinced that this is the key fault in the theory. The theory doesn't distinguish acts by people from those by machines. |
| 6854 | Does the environment have value in itself? [Crisp,R] |
| Full Idea: The debate which dominates environmental ethics is whether the environment has value in itself. | |
| From: Roger Crisp (Interview with Baggini and Stangroom [2001], p.37) | |
| A reaction: I say the answer has to be 'yes'. If it only has value in relation to conscious or human life, it will be difficult to demonstrate that they have value. Pleasure and pain, or wisdom, can't imply value on their own; a bigger picture is needed. |
