I did a long, long post on eliminative materialism once, and now it will never be found again. A search was unsuccessful.

I'll try to recreate it, but I may miss points I made before.
Basically, eliminative materialism is a theoretical stance put forth as an alternative to so-called "common-sense", "ordinary", or "folk psychology" ways of understanding the mind and mental states. (There may very well be eliminativist methods which can be used in order to discuss or understand specific concepts-- in other words, essentially denying the existence of whatever is being discussed or understood-- but that's not what we're talking about here; this is the original theory.) Earlier forms of eliminative materialism were really impossible to tell apart from reductive materialism in most ways, because they posited that mental states were basically reducible to brain states. In the 1970's and 1980's, however, as developed by people like Paul and Patricia Churchland, eliminative materialism became a radically different theoretical outlook. Under this theory, mental states are
not reducible to neurological states, even though they do take place only in the brain (in contrast to what someone like Dennett is actually arguing, so I do have to give him that much.) And no matter how elaborately this is explained, it never really does seem to go beyond this bizarre combination of reductionism and dualism. A number of objections to so-called "common-sense" psychology are certainly brought up, but when examined, they all boil down to the same thing: the theoretical framework which poses our behavior and mental states as being controlled by our beliefs is somehow faulty. "Folk psychology" is classified with "folk physics, folk biology, and folk epidemiology", none of which turned out to accurately represent the natural world. Analogies are repeatedly and regularly drawn between "folk psychology" and beliefs in demons, angels, apparitions of God, etc., complete with clear statements that the psychological and psychiatric community will soon discard all theoretical models related to "folk psychology" just as surely as this outmoded medieval silliness was discarded.
There are many different arguments against eliminative materialism, none of which I'm going to get into here, but I think that the problems with these arguments themselves can be best summed up by this quote:
Defenders of folk psychology object that these theoretical considerations cannot outweigh the evidence provided by everyday, ordinary experience of our own minds, such as our introspective experience, which seems to vividly support the reality of mental states like beliefs.
Nobody who argues against eliminative materialism seems to have understood the way that Paul and Patricia Churchland have really pulled the wool over everyone's eyes any better than this, and there's really something almost unbelievable about it to me. If anyone's ever seen the "color-changing card trick" video, the arguments against eliminative materialism reminded me of nothing so much as that. When we watch it, we're trying so hard to keep our eyes on our cards that we don't notice the way that the colors of everything
else in the entire video have changed. Then, there's that little problem with not noticing the gorilla in the background...
The very first thing which anyone should have picked up on in the eliminative materialism argument is the idea of "folk" or "common sense" psychology. It is the absolute foundation of this theory, because everything is defined in opposition to it. But it is never clearly defined. Who are the folk? What is the common sense? What is the theoretical basis? Who came up with it? Who defined it, and where is the definition recorded? Which scientists and researchers worked on it? What is its history?Where are the books and articles about it? Where are the studies on it? Who has argued for and against it? What are its parameters? Exactly which claims are and are not made by it?
Not even one of these questions is answered, and yet this incredibly vague definition of the supposed theoretical platform against which eliminative materialism is itself defined is allowed to stand. Nobody ever,
ever questions it. Unbelievable. That's the only word. But somebody certainly should question it, because when the Churchlands yap on and on about "folk psychology", they know exactly what they're talking about, and that's not it. They're being very sneaky about attacking an established theory of mind without ever calling it by name, and I think the reason why they do this is that they know they could never succeed if they took it on directly.
What we
do see in the history of eliminative materialism is that the theory itself began to radically change at a very specific point in time. The time when it changed is the key to what really happened, and what true eliminative materialism really is.
Before the late 1970's and early 1980's, it was essentially the same thing as reductive materialism.
After this point in time, what it was really arguing was that our beliefs don't determine our mental states or our behavior, but that our behavior stands on its own.
Stripped of its weaselly claims to represent something else, guess what this is? Straight, good old-fashioned behaviorism. And I have to say that I think this is what the Churchlands have been always been arguing for. But to understand how all of this makes sense, we have to look at what else was happening in the mid 1970's and early 1980's. Dr. Aaron Beck was developing his cognitive-behavioral theories. Unlike eliminative materialism, it was never intended as a set of ivory tower mental exercises, but as a practical and therapeutical tool against depression. His pioneering work,
Cognitive Therapy of Depression, was published in 1979, and he laid out the foundations of his theories. Our mental states are perpetuated by our beliefs about ourselves, the world around us, and our future. If these are negative, they create the negative cognitive triad. This triad must be broken through examining and identifying irrational negative beliefs, and then by modifying them through practical therapeutic techniques.
Even though this is called cognitive-behavioral therapy, the truth is that it's strayed pretty far from the behavioral roots, especially by the 1990's, by which time Paul and Patricia Churchland were really going strong.
In CBT, the negative beliefs are understood to take place on three levels: surface, intermediate, and core. We acknowledge these realities, because if we don't, people will not get better. And the key to the entire thing is that CBT is now THE standard evidence-based practice for a very wide range of pathologies, from depression to anxiety to panic disorder to anger management to antisocial disorder to addictions to obsessive-compulsive disorder to... it's a long list. How do we know? That's the best part of all.
We know this because CBT has been proven, as it must be, through the empirical tools of evidence-based practice. It has been proven to work better than other therapeutic treatments in over 100 studies, as measured by improvement on every kind of standardized testing instrument. Something like eliminative materialism doesn't ever have to be subjected to this kind of testing, because it is not a real world application. People like the Churchlands don't ever HAVE to find out if it works in the real world, and if they did have to, they'd be in for quite a shock, because it really is nothing but behaviorism. And in clinical practice, behaviorism does not work, and CBT does. That's why it's standard clinical treatment and behaviorism is not. That's why we use CBT in applications in the real world, in clinics, schools, hospitals, nursing homes, outpatient and inpatient mental health, and everywhere else you could ever think of. "Folk psychology" is no such thing, and people like the Churchlands know it-- it's really CBT theory, the theory that our beliefs determine our mental states and our behavior, and it has been proven over and over and over again to be true in in the real world. If they want to try to prove that it's
not true, then let them actually come out and test its practical application, which is behaviorism. But it would be nice if they could be honest about what they're really arguing with eliminative materialism, because they're not being honest.
