Nobody denies that behaviorism does not provide us with limited but useful results, and to that extent behaviorism is wonderful. The point is that its results are *extremely limited*. And there are fairly strong reasons to suspect that they will always be *extremely limited*. See Chomsky's review of Skinner's _Verbal_Behavior_ for starters: Either Behaviorism cannot account for language, or else it must use mentalistic constructs in disguise. Catch 22. >2) Evidence for free will is found in internal observation. > >> ... beliefs, thoughts and desires are causal determinants of >> human action .... The evidence is plentifully available in the >> form of 1st person experience... > This is classic dualist retort. One needn't believe in mental substance to believe in mind unless you are some kind of substance ontologist. The only dualisms I see are formal (what extensional logics can deal with versus what requires intensional logic) and epistemological (what is public versus what is private). "Physical substance" itself is increasingly becoming an incoherent idea. The future of reductionism is not very bright. > The problem is then just shifted > to where do beliefs, thoughts and desires come from. That's another question. You have skirted the issue of what beliefs and desires actually are. >I am affirming a) that beliefs etc. are causes and b) that >they are important to the person experiencing them. You mean to say that the beliefs and desires of your lover aren't important to you? I say (b) is just baloney if by that you mean they are important *only* to the person experiencing them. They are important to anybody who really cares about you. Furthermore, they are important to anybody who cares about what is indeed true. Even the "strong AI" dream of building a robot that passed the Turing test would need to be able to manipulate formal objects that represented the beliefs and desires of others as well as its own. Stop confusing epistemology with ontology. >I also am saying that they are scientifically unimportant since > 1) there is nothing we can do about them directy (we can only change > the things that control them) and That's like saying I can't drive a car since I can't control it "directly", say, by psychokinesis. Anyway, whenever I will something I am as close to "directly" doing something as I'd ever care to get. It is just a fact that my desires almost always control my actions. Will just is a desire that is controlling my current action. This is explicandum, not explicans. I want to know how it happens. To say this is "scientifically unimportant" is most presumptious indeed coming as it does from a discipline with as low credibility as behaviorism. There are other competing scientific theories with other claims about what counts as "scientifically important" besides behaviorism. > 2) we can only have direct access to our own experience and no one > can ever have direct access to our experience.

But that is no reason whatsoever why science cannot correlate 1st person "subjective" reports with neurophysiological findings. In fact, I'd go so far as to say that these amount to the some of the most interesting scientific facts uncovered to date (such as the Penfield experiments). It is just this information that promises to be the most valuable from my perspective: We have this interior mental life. What can science tell us about it? Your reply is to say "Nothing at all. Science isn't up to the task" I say "Baloney!". Any science worthy of the name must investigate the phenomena or else remain silent about them. >3) The assumptions of materialistic determinism is fundamentally > undermined by quantum-mechanics.

QM + chaos theory provides just the rigorous scientific argument needed to blast away any claims of deterministic mechanism for sufficiently complex systems, of which the brain easily counts as an example. Chaos theory predicts global sensitivity to minor fluctuations *everywhere*. QM provides minor fluctuations *everwhere*. Determinism loses. The real problem is how we manage so well to control our actions in spite of all this metaphysical randomness. > Materialistic determinism works as the starting > assumption when confronted by a new disease and it would be silly > to think otherwise. No doubt deterministic theories are the best working hypothesis for the technical specialist who, lets face it, knows practically nothing about what's really going on. After all, we want to find predictive laws. If and when they have a theory that successfully predicts the way people do behave better than folk psychology, and when they have shown us how beliefs and desires really do cash out into neurophysiological terms, then these methodological claims (these are currently just methodological heuristics, not even scientific findings themselves, and absolutely not proven facts, remember?) will be worth taking seriously as a priori claims. >4) The main threat of behaviorism is that it is systematic control. >> It doesn't matter one whit to whether one's actrions are ... >>... determined ... as long as they're not determined by the *intentional >> manipulation* of another *conscious* being. > It would seem that any part of society would fall under this, > laws, schools, jobs and any where else ones behavior is being > directed by others. Manipulation isn't just wrong, it's counterproductive. It is not treating a person honestly. Admittedly, there may be criminally or mentally deranged people for whom such manipulation might count as the lesser evil where honest approaches fail. And there may be people who rationally consent to such treatment when they know they have lost rational control of their own actions, as in the case of addictions. You seem to confuse "behavior direction" with "convincing the other to act". Only one who doesn't believe in beliefs and desires could fail to see the difference. > If you say that *any* of these are ok then you are saying that > behavior control has a place in society. > If you say that *all* of these are bad then you are merely a > radical anarchist and there is no place for society. If laws, schools, and jobs don't treat people as rational agents is it any wonder so many of us are just bozos? Maybe there isn't any place for me in a society, if that be one of bozoes. >As a retort to Hilary Putnam's thesis about Functionalism ... it seems >that the human brain is more of an open system than is a Turing Machine. That's precisely one of Hilary Putnam's points if I am not mistaken. -michael
