18. Thought / C. Content / 5. Twin Earth
Two types of water are irrelevant to accounts of behaviour [Kim]
     Full Idea: The difference in the two types of 'water' in the Twin Earth experiment seem psychologically irrelevant, for behaviour causation or explanation.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.203)
     A reaction: A rather important point. No matter how externalist you are about what content really is, people can only act on the internal aspects of it.
Two identical brain states could have different contents in different worlds [Kim]
     Full Idea: States that have the same intrinsic properties - the same neural/physical properties - may have different contents if they are embedded in different environments.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.146)
     A reaction: This is a way of expressing externalism. It depends what you mean by 'contents'. I struggle to see how "H2O" could be the content of the word 'water' among ancient Greeks.
18. Thought / C. Content / 6. Broad Content
Our meanings are partly fixed by events of which we may be ignorant [Davidson]
     Full Idea: What we mean by what we say is partly fixed by events of which we may be ignorant.
     From: Donald Davidson (Davidson on himself [1994], p.235)
     A reaction: There is 'strict and literal meaning', which is fixed by the words, even if I don't know what I am saying. But 'speaker's meaning' is surely a pure matter of a state of mind?
External identification doesn't mean external location, as with sunburn [Davidson, by Rowlands]
     Full Idea: Davidson observes that the inference from a thought being identified by a relation to something outside the head does not entail that the thought is not wholly in the head, just as sunburn is identified by external factors, but is still in the skin.
     From: report of Donald Davidson (Knowing One's Own Mind [1987]) by Mark Rowlands - Externalism Ch.8
     A reaction: Rowlands (an externalist) agrees, and this strikes me as correct, and it needs to be one of the fixed points in any assessment of externalism.
It is widely supposed that externalism cannot be reconciled with first-person authority [Davidson]
     Full Idea: It has been widely supposed that externalism, which holds that the contents of a person's propositional attitudes are partly determined by factors of which the person may be ignorant, cannot be reconciled with first-person authority.
     From: Donald Davidson (Epistemology Externalized [1990], p.197)
     A reaction: It is certainly a bit puzzling if you go around saying 'Actually, people don't know their own thoughts'. Davidson aims to defend first-person authority. The full story is developed in Tyler Burge's views on 'anti-individualism'.
It is hard to interpret a speaker's actions if we take a broad view of the content [Davidson]
     Full Idea: It will explain a speaker's actions far better if we interpret him as he intended to be interpreted, than if we suppose he means and thinks what someone else might mean and think who used the same words 'correctly'.
     From: Donald Davidson (Epistemology Externalized [1990], p.199)
     A reaction: This comes down to the fact that our actions have to be motivated by internal meanings. If I defer to experts on the essence of gold, I still buy gold according to how I myself understand it. So meaning has two components?
'Arthritis in my thigh' requires a social context for its content to be meaningful [Kim]
     Full Idea: The example of someone claiming "arthritis in my thigh" shows that the content of belief depends, at least in part but crucially, on the speech practices of the linguistic community in which we situate the subject.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.197)
     A reaction: Personally I find this social aspect to meaning to be more convincing that Putnam's idea that the physical world is part of meaning. It connects nicely with the social aspects of justification.
Content is best thought of as truth conditions [Kim]
     Full Idea: It is standard to take contents as truth conditions.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.203)
     A reaction: This tradition runs from Frege to Davidson, and has been extended to truth conditions in possible worlds. Rivals will involve intentions, or eliminativism about meaning.
Content may match several things in the environment [Kim]
     Full Idea: If content is said to be 'covariance' with something in the environment, then the belief that there are horses in the field covaries reliably with the presence of horses in the field, but also the presence of horse genes in the field.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.192)
     A reaction: That's the end of that interesting proposal, then. Or is it? Looking at the field from a distance this is right, but down the microscope, the covariance varies. The theory lives on.
18. Thought / C. Content / 7. Narrow Content
Pain, our own existence, and negative existentials, are not external [Kim]
     Full Idea: No external factors seem to be required for Fred's belief that he is in pain, or that he exists, or that there are no unicorns.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.198)
     A reaction: This is an extremely important observation for anyone who was getting over-excited about external accounts of content. Unicorns might connect externally to horns and horses.
Content depends on other content as well as the facts [Kim]
     Full Idea: An objection to the 'covariance' theory of content is that what you believe is influenced, often crucially, by what else you believe.
     From: Jaegwon Kim (Philosophy of Mind [1996], p.193)
     A reaction: I can't think of a reply to this, if the covariance theory is suggesting that content just IS covariance of mental states with the environment. Externalism says that mind extends into the world.
