    A little background in what's meant by "content externalism:"

    "Externalism—whether of content or vehicle—is often viewed as a peculiar eruption of late twentieth-century analytic philosophy. This, however, is historically myopic. Cognate views with fairly clear externalist credentials have been advanced and defended much earlier than this, and in some of the defining works of twentieth-century philosophy (see Rowlands 2003: Chapters 3&4). Wittgenstein (1953) argued that meaning something by a sign does not consist in an inner state or process. Rather, the possibility of such meaning depends essentially on the existence of a custom or practice of using a sign in given way, and the mastery of a technique—i.e., the ability to adjust one’s use of the sign to bring in into accordance with this custom. According to the dominant—community—interpretation of the notion of a custom, this entails that the possibility of meaning something by a sign is dependent on the existence of a practice external to the individual meaner, and that what this individual means by a sign on any given occasion depends, at least in part, on this external practice. As we shall see, this social version of content externalism was later developed, powerfully, by Burge (1979, 1986)." -- SEP on externalism.

    The prevailing form of mental content externalism only says that some content is external. A more rare and somewhat confused version says that all mental content is external.

    I think this brand of externalism leads to behaviorism and a pending collapse in meaning of any kind anywhere. How can this be avoided?

    And a reminder about what's meant by "behaviorism":

    "Behaviorism
    Behaviorism was a movement in psychology and philosophy that emphasized the outward behavioral aspects of thought and dismissed the inward experiential, and sometimes the inner procedural, aspects as well; a movement harking back to the methodological proposals of John B. Watson, who coined the name. Watson’s 1913 manifesto proposed abandoning Introspectionist attempts to make consciousness a subject of experimental investigation to focus instead on behavioral manifestations of intelligence. B. F. Skinner later hardened behaviorist strictures to exclude inner physiological processes along with inward experiences as items of legitimate psychological concern. Consequently, the successful “cognitive revolution” of the nineteen sixties styled itself a revolt against behaviorism even though the computational processes cognitivism hypothesized would be public and objective — not the sort of private subjective processes Watson banned. Consequently (and ironically), would-be-scientific champions of consciousness now indict cognitivism for its “behavioristic” neglect of inward experience.

    The enduring philosophical interest of behaviorism concerns this methodological challenge to the scientific bona fides of consciousness (on behalf of empiricism) and, connectedly (in accord with materialism), its challenge to the supposed metaphysical inwardness, or subjectivity, of thought. Although behaviorism as an avowed movement may have few remaining advocates, various practices and trends in psychology and philosophy may still usefully be styled “behavioristic”. As long as experimental rigor in psychology is held to require “operationalization” of variables, behaviorism’s methodological mark remains. Recent attempts to revive doctrines of “ontological subjectivity” (Searle 1992) in philosophy and bring “consciousness research” under the aegis of Cognitive Science (see Horgan 1994) point up the continuing relevance of behaviorism’s metaphysical and methodological challenges." --IEP entry on behaviorism.

    Why doesn't hard content externalism lead to behaviourism?frank

    Not that we should assume there would automatically be some awful problem if it did. But,

    I think Chomsky avers (somewhere on youtube) that Hume and Heraclitus were privy to the same insight [the inscrutability of reference]. Of course he draws a different lesson from it than Quine. But he doesn't say the doctrine itself is mistaken, or even that it is behaviouristic. And it isn't. It points out that you can't objectively ground reference in behaviour.bongo fury

    It's a game of pretend. There won't be any fact of the matter of exactly what anyone was pretending. How could there?

    It (meaning, mental content, what have you) is a game of pretending that words and pictures refer to things (externally, not in the head). We're just second guessing each other's fantasies about the reference. We can't use observed behaviour to justify any particular fantasy.

    But the kind of behaviorism I'm thinking of doesn't allow that there is any kind of referencing involved in communication.

    Speech itself is merely behavior. Some behaviors are repeated because they bring about something positive.

    Wouldn't a sort of "hard" externalism seem to mesh with that kind of behaviorism?

    frank

    Fair enough. By justify I meant choose. If there were some fact of the matter of which symbols mapped to which things then behaviourism wouldn't be wrong to reduce or replace that mapping (the reference that 'happened') with some description of behaviour. But according to Quine there is always a choice of mappings. We never know for sure what 'happened'. We have to play the game of pretend, and allow for, second guess, multiple hypotheses of what was pretended.

    Which is how a 'hard' externalism about the mappings, i.e their not being in the head, can fail to mesh with behaviourism.

    If we're planning to do some scientific research on what's in our heads, I think he would say we shouldn't do that due to the unavailability of facts.

    That's a hard solution to avoid as "strong" content externalism just seems like a version of behaviorism.

    I suppose that one can argue that the content of our perceptions are veridical only when the external content actually coincides with what we imagine. That is if the cow we think we see is actually a cow. So on this view, thinking that you see a cow that turns out to be sheep would be equivalent to saying that the content in your head is false. So even if you think you saw a cow, your thinking that you say it is not content after all.

    But this just makes no sense. It's an arbitrary stipulation on what content is, which leaves out almost everything.

    If, however, you use content externalism in a much less radical manner, then perhaps it can be articulated a little.

    It rules out almost everything. A human being is reduced to a stimulus-reacting nothing. You wouldn't be able to tell a human from an amoeba under strong behaviorism. So it's not even good science, unless it's radically altered.

    But there really isn't anything newsworthy about weak content externalism, is there?frank

    Nope. Not that I can see. Yet I see more papers talking about externalism of all varieties than internalism, which is coherent and looks to me to be scientific. Everybody's internalist when it comes to other animals, we all assume they have an intrinsic nature such that a dog will behave dog-like and not chimp -like, etc.

    But when it comes to human beings, internalism becomes this mysterious magic stuff to some. This is strange to me.

    Under strong behaviorism, how would you know that?

    Any movement made by the amoeba can be taken as sign that it is reacting to the poem.

    But of course amoeba's don't react to poems and humans do, as you point out. So you need to postulate an innate mechanism that allows human beings to react to poems that amoeba's lack.

    If it's based on behavior alone, without assuming an innate structure to each creature, I don't see how one could make that distinction, unless you believe there is no difference between creatures.

    How do you think we found anything out about amoebae then? Theories all rely on repeatability. If the amoeba repeatedly responds to a poem in some predictable way (but not to some control, like a random collection of words), then we've got everything we thought about amoebae pretty wrong haven't we?

    you need to postulate an innate mechanism that allows human beings to react to poems that amoeba's lack.Manuel

    It's difficult to generalize in this respect, there are philosophers who accept internalism without much problems such as Strawson, Chomsky, Haack, McGinn, etc.

    I suspect some philosophers think that by sticking to externalism, they're putting aside spooky stuff like experience (looking at the blue of the sky, or explicitly thinking about a beach, etc.) and then stick to things that are publicly observable and hence be "scientific". It's hard to say.



    I don't agree. Putnam, for example, suggested the thought experiment of a brain-in-vats as an exercise. Nobody literally believes we are brain in vats, though some believe in the simulation hypothesis. It's still useful to look at what extreme ideas would look like.

    I think that in principle, if we knew enough about the brain we wouldn't need an external world. You would just need to stimulate the appropriate are of the brain to recreate an experience which would be indistinguishable from one in ordinary life.

    Granted, this scenario is science fiction, but I think the principle is correct. The main point I take from it is that the world is not necessary to explain our experience.

    But as you hinted at, what's useful depends on the person involved. I don't find the "do machines think?" question to be useful, but clearly, other people do.
