9 ideas
2986 | Belief is the most important propositional attitude [Lyons] |
Full Idea: Belief might be accorded the status of core or chief propositional attitude. | |
From: William Lyons (Approaches to Intentionality [1995], p.126) |
2978 | Consciousness no longer seems essential to intentionality [Lyons] |
Full Idea: In contrast with Brentano and Husserl, consciousness or attention are no longer seen as essential to intentionality. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: This strikes me as being correct, although there seem to be plenty of current philosophers who do not accept it (e.g. Searle). I think philosophy of mind may be stuck in the dark ages if thinkers don't accept this proposal. |
2984 | Perceptions could give us information without symbolic representation [Lyons] |
Full Idea: It is possible to give an account of concept-formation without a language of thought or representation, based on perception, which in the brain seems to involve information without representation. | |
From: William Lyons (Approaches to Intentionality [1995], p.66) | |
A reaction: This claim strikes me as being a little too confident. One might say that a concept IS a representation. However, the perception of several horses might 'blur' together to form a generalised horse. |
2979 | Propositional attitudes require representation [Lyons] |
Full Idea: How else, other than via some form of representational system, could a human organism contain information as a content over which it could operate or 'attitudinise'? | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Depends what you mean by 'representational'. In its vaguest sense, this is just a tautology - content must be held in the mind in some form or other, but that tells us nothing. |
2987 | Folk psychology works badly for alien cultures [Lyons] |
Full Idea: It is not easy to employ our folk psychology in the understanding of persons in a very different culture. | |
From: William Lyons (Approaches to Intentionality [1995], p.241) | |
A reaction: This strikes me as a highly significant problem for the friends of folk psychology. It also breaks down in extreme situations, or with mental illness. It seems closer to culture than to brain structure. |
3979 | The Turing Machine is the best idea yet about how the mind works [Fodor on Turing] |
Full Idea: Alan Turing had (in his theory of the 'Turing Machine') what I suppose is the best thought about how the mind works that anyone has had so far. | |
From: comment on Alan Turing (Computing Machinery and Intelligence [1950]) by Jerry A. Fodor - Jerry A. Fodor on himself p.296 | |
A reaction: I am not convinced, because I don't think rationality is possible without consciousness. The brain may bypass the representations used by a computer. |
5321 | In 50 years computers will successfully imitate humans with a 70% success rate [Turing] |
Full Idea: In about fifty years' time it will be possible to program computers to play the imitation game so well that an average interrogator will not have more than 70% chance of making the right identification after five minutes of questioning. | |
From: Alan Turing (Computing Machinery and Intelligence [1950], p.57), quoted by Robert Kirk - Mind and Body §5.9 | |
A reaction: This is the famous prophecy called 'The Turing Test'. The current state (2004) seems to be that the figure of 70% is very near, but no one sees much prospect of advancing much further in the next 100 years. Dennett sees jokes as a big problem. |
2977 | All thinking has content [Lyons] |
Full Idea: I cannot say I am simply thinking but not thinking about anything. | |
From: William Lyons (Approaches to Intentionality [1995], Intro) | |
A reaction: Hard to disagree. However, I can plausibly reply to 'What are you thinking?' with 'Nothing', if my consciousness is freewheeling. Utterly disconnected content isn't really what we call 'thinking'. |
1743 | The greatest deterrence for injustice is if uninjured parties feel as much indignation as those who are injured [Solon, by Diog. Laertius] |
Full Idea: Men can be most effectively deterred from committing injustice if those who are not injured feel as much indignation as those who are. | |
From: report of Solon (reports [c.600 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 01.So.10 |
