Talk:Intentional stance

From Wikipedia, the free encyclopedia

The essay I removed from the article is below.


“...all there is to being a true believer is being a system whose behaviour is reliably predictable via the intentional strategy.” (Dennett, “True Believers”).


Dennett’s Intentional Strategy sets out the conditions for predicting the behaviour of an intentional object as follows: 1) Treat the object as a rational agent 2) Decide what beliefs and desires the object ought to have, given what sort of thing it is and what its circumstances are 3) Predict the object’s behaviour on the assumption that it will act “to further its goals in the light of its beliefs”2

This is meant to be an improvement on folk psychology, borrowing its terms and giving them a new meaning within the intentional systems theory (IST), which deals specifically with “the prediction and explanation from belief-desire profiles of the actions of whole systems, but treats the individual realisations of the systems as black boxes” It is also meant as a refutation of functionalist theories, which claim that intentional states are literally causal, and identity theories, which claim that belief a is identical with brain-state a. Instead, Dennett claims that our talk about minds does not refer to anything concrete, but to useful fictions, just as economists refer to imaginary entities like ‘the average taxpayer’. Dennett points out that our knowledge of folk psychology is a little like our knowledge of natural language ; we don’t learn it by definitions, but through use. Thus its continued existence rests not so much on it being a true account of mental activity as the fact that it works.

Dennett gives us two premisses about intentional states:

1) that intentional states are not concrete things, but concepts we have invented to be able to explain behaviour,

2) that there is no hope of getting rid of our talk of intentional states. As Jerry Fodor notes, “we have no idea of how to explain ourselves to ourselves except in a vocabulary which is saturated with belief/desire psychology.”

From these, he claims it follows that we should continue to talk about intentional states to explain and predict behaviour (albeit using his improved version of folk psychology, the intentional systems theory), but we should not then make the move to saying that we know what it is inside the system that is causing our theory to work. By treating intentional systems as ‘black boxes’, Dennett is able to extend the set to include not just humans and animals but plants, machines; theoretically even lightning. He can do this because now that the intentional states of humans are being treated as useful fictions, there is nothing special about them, within the theory, to make them ‘more real’ than the beliefs or desires of a photo-trophic plant or a thermostat. The most obvious objection to Dennett is the instinctive thought that it matters to us whether an object has an inner life or not. You don’t just imagine the intentional states of other people in order to predict their behaviour; the fact that they have thoughts and feelings just like you do is central to notions such as trust, friendship and love. The ‘Blockhead’ argument , as it is known, proposes that Jones has a twin who is in fact not a person but a very sophisticated robot, who looks and acts like Jones in every way, but who does not have any thoughts or feelings at all, just a chip which controls his behaviour ; in other words, ‘the lights are on but no one’s home’. According to the intentional systems theory, Jones and Blockhead have precisely the same beliefs and desires, but this seems false. The IST expert assigns the same mental states to Blockhead as he does to Jones, “whereas in fact (Blockhead) has not a thought in his head” The problem with this objection is it assumes that IST claims to tell us true things about our mental states, which it does not. In fact it remains agnostic about what beliefs and desires ‘really’ are in human beings, and uses intentional terms in a purely technical way to predict behaviour. Discovering that Blockhead is an automaton may have many implications for the people around him, but what it will not do is change the way they should reason about his behaviour. There is another objection, which attacks the premise that treating people as ideally rational creatures will yield the best predictions. Stephen Stich points out that people often have beliefs or desires which are irrational or bizarre, and IST doesn’t allow us to say anything about these. Of course if the person’s ‘environmental niche’ is examined closely enough, and the possibility of malfunction in their brain (which might affect their reasoning capacities) is looked into, it may be possible to formulate a predictive strategy specific to that person. Indeed this is what we often do when someone is behaving unpredictably - we look for the reasons why. This development takes away from the simplicity of the theory but is not explicitly an argument against it. A third objection takes the reverse case to the Blockhead example: a person who is completely paralysed. They have no behaviour and so IST should reason that therefore they have no intentional states. The solution to this is problematic: the IST expert looks to their circumstances and says: they probably have the belief that they are paralysed, and the desire that they weren’t, and I predict from these that their behaviour will be nil, hence, IST works. But could anything, then, be an intentional system? What about a lectern? Why not say that a lectern mourns the fact that it used to be a tree, and desires to be one again, but due to its circumstances it just stays where it is? This presents a strong challenge to the claim that IST can adequately account for beliefs and desires, for we surely do not want to say that a lectern is an intentional system. The rationale behind the intentional stance is based on evolutionary theory, assuming that the ability to make quick predictions of a system’s behaviour based on what we think it might be thinking was an evolutional advantage. The fact that our predictive powers are not perfect is a further result of the advantages sometimes accrued by acting contrary to expectations. If we take the intentional stance at face value; that is, as a conceptual tool and not as a literal definition of the mind, then it works in a roughly constructive empiricist fashion: to yield accurate results. “What is done, not how it is done, is what counts” ; and the intentional stance may help us to understand the mind better than many other available theories which make stronger claims but are more easily refuted. It is easy to make the objection that it falls short of telling us the whole story, but Dennett never meant it to be the whole picture. The challenge then is to come up a theory of consciousness which can adequately describe what significant difference, if any, there is between humans and other intentional systems. Such a theory would sharpen the distinctions between different levels of intentionality and perhaps satisfy those who are uncomfortable with Dennett’s attribution of beliefs and desires to any system which displays behaviour.

[edit] Hmmmm???

I need some clarification on this, A. First of all, is it your intention that this articile be about the book Intentional Stance, the concept intentional stance or both. If it's about the book, I can include the template infobox book and you (I don't have a copy of the book unfortunanely nor am I close to a library) can fill out the details (publisher, etc.). If you are just covering the concept intentional stance, then you should try to include some alternative views and definitely add references (at least to Dennet himself!), further readin and so on: make it a full article, on other words. Second of all, I assume it was you that posted the above comments. If so, what was the problem with this material?? In the meantime, I'll just look it over for grammar, sentence structure and any obvious factual errors.--Lacatosias 15:23, 10 March 2006 (UTC)

The stuff above was by Kelly Martin, so I can't comment on their intentions.
However, I've always seen this article as being about the concept developed in The Intentional Stance and Consciousness Explained, not just that first book. You'll note that the article name lacks the "the" from the book title.
I'm all for additional references and some alternative views. Want to help out in this regard? Alienus 16:42, 10 March 2006 (UTC)
That's what I finally surmised. In any case, I basicaly reintroduced some of the interesting material regarding criticism and responses from what I found on this page back into the article. I aslo added the refenences. I don't have very much material of my own, but I do remember coming across one or two criticims of Dennett's evolutionary basis (or justification?) of the intentional stance. I don't know what Dennettìs reply would be, but this might be intersting to add as well. Perhaps tomorrow I will work on it a bit, since it's getting a bit late over here already. --Lacatosias 17:07, 10 March 2006 (UTC)
Sounds good. I'll keep an eye on it and do a clean-up pass after you're mostly done. Alienus 17:39, 10 March 2006 (UTC)
