| 2620 | Dualism is a category mistake [Ryle] |
| Full Idea: The official theory of mind (as private, non-spatial, outside physical laws) I call 'the dogma of the Ghost in the Machine'. I hope to prove it entirely false, and show that it is one big mistake, namely a 'category mistake'. | |
| From: Gilbert Ryle (The Concept of Mind [1949], I (2)) | |
| A reaction: This is the essence of Ryle's eliminitavist behaviourism. Personally I agree that the idea of a separate 'ghost' running the machine is utterly implausible, but it isn't a 'category mistake'. The mind clearly exists, but the confusion is about what it is. |
| 2388 | Behaviour depends on desires as well as beliefs [Chalmers on Ryle] |
| Full Idea: Another problem for Ryle (from Chisholm and Geach) is that no mental state could be defined by a single range of behavioural dispositions, independent of any other mental states. (Behaviour depends upon desires as well as beliefs). | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by David J.Chalmers - The Conscious Mind 1.1.2 | |
| A reaction: The defence of behaviourism is to concede this point, but suggest that behavioural dispositions come in large groups of interdependent sets, some relating to beliefs, others relating to desires, and each group leads to a behaviour. |
| 3354 | You can't explain mind as dispositions, if they aren't real [Benardete,JA on Ryle] |
| Full Idea: Ryle is tough-minded to the point of incoherence when he combines a dispositional account of the mind with an anti-realist account of dispositions. | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by José A. Benardete - Metaphysics: the logical approach Ch.22 | |
| A reaction: A nice point, but it strikes me that Ryle was, by temperament at least, an eliminativist about the mind, so the objection would not bother him. Maybe a disposition and a property are the same thing? |
| 2387 | How can behaviour be the cause of behaviour? [Chalmers on Ryle] |
| Full Idea: A problem for Ryle is that mental states may cause behaviour, but if mental states are themselves behavioural or behavioural dispositions, as opposed to internal states, then it is hard to see how they could do the job. | |
| From: comment on Gilbert Ryle (The Concept of Mind [1949]) by David J.Chalmers - The Conscious Mind 1.1.2 | |
| A reaction: I strongly approve of this, as an objection to any form of behaviourism or functionalism. If you identify something by its related behaviour, or its apparent function, this leaves the question 'WHY does it behave or function in this way?' |
| 2331 | Functionalism says robots and people are the same at one level of abstraction [Putnam] |
| Full Idea: My "functionalism" insisted that a robot, a human being, a silicon creature and a disembodied spirit could all work much the same way when described at the relevant level of abstraction, and it is wrong to think the essence of mind is hardware. | |
| From: Hilary Putnam (Representation and Reality [1988], Int p.xii) | |
| A reaction: This is the key point about the theory - that it is an abstract theory of mind, saying nothing about substances. It drew, however, some misguided criticisms suggesting silly implementations. |
| 2071 | If concepts have external meaning, computational states won't explain psychology [Putnam] |
| Full Idea: Computational models of the brain/mind will not suffice for cognitive psychology. We cannot individuate concepts and beliefs without reference to the environment. Meanings aren't "in the head". | |
| From: Hilary Putnam (Representation and Reality [1988], p.73) | |
| A reaction: Mr Functionalism quits! |
| 2332 | Functionalism can't explain reference and truth, which are needed for logic [Putnam] |
| Full Idea: Functionalism has as much trouble with physical accounts of reference as of meaning. Reference is the main tool used in formal theories of truth. But 'truth' isn't folk psychology, it is central to logic, which everyone wants. | |
| From: Hilary Putnam (Representation and Reality [1988], Int p.xiv) | |
| A reaction: All logic is defined in terms of truth and falsehood resulting from reasoning, but it could be that 'true' and 'false' have no more content that 1 and 0 in binary electronics. They are distinct, but empty. |
| 2348 | Is there just one computational state for each specific belief? [Putnam] |
| Full Idea: The idea that there is one computational state that every being who believes that there are lots of cats in the neighbourhood is in must be false. | |
| From: Hilary Putnam (Representation and Reality [1988], §5 p.84) | |
| A reaction: It is tempting to say that the mental states of such people must have SOMETHING in common, until you realise that all you can specify is that all their states are about cats. |
| 2344 | If we are going to eliminate folk psychology, we must also eliminate folk logic [Putnam] |
| Full Idea: Why don't the eliminationists speak of "folk logic" as well as "folk psychology"? | |
| From: Hilary Putnam (Representation and Reality [1988], §4 p.60) | |
| A reaction: I think Putnam considers that if you can prove 'truth' to be a necessary feature of mental life, that connects mind and world, but marking a sentence as 'T' doesn't make any connections. |
