                I agree with John. If consciousness had no third-person

to
                explain why we're even having this discussion about 
consciousness.

                So we all agree on this.

                ?? Why aren't first person observable effects enough to discuss?


            I guess because if there are no third-person observable effects of
            consciousness, then I can't detect any other conscious entities to
            discuss the effects with...

            The epiphenomenon model says there are third-person observable 
effects of
            the phenomenon, which suffice for detecting other entities.  
Whether the
            other entities are really conscious or just faking it is a matter of
            inference.


        Did you mean to say "The epiphenomenon model says there are *no* 
third-person
        observable effects of the phenomenon" ?

        Of course not.  The phenomenon is what is observable, by definition.  
It's the
        epiphenomenon which is not third-person observable.


    But in the epiphenomenon model, consciousness is the epiphenomenon and the
    phenomenal part of consciousness is its first-person aspect.

    The statement was, "there are no third-person observable effects of 
consciousness".


Yes this is the conventional meaning of epihenominalism (in philosophy of mind).

    In the epiphenomenal theory of consciousness, I take the phenomenon to be 
the
    observable behavior, neuron firings, etc. and consciousness the 
corresponding
    epiphenomenon.


Okay.

    Those phenomenon do have third person observable effects and in general 
that's how
    we infer consciousness in others.


I agree. But I think epiphenominalism is false, because that it places consciousness outside the causal chain of physics, making it "extra physical" ineffectual, and for all intents and purposes, unnecessary (it declares no ability to ever move beyond solipsism as far as determining whether some other thing or process is conscious or not).

Those sound like reasons you don't like it, not reasons it's false. Are you echoing JKC's line that if consciousness is not effacious evolution would have removed it? If consciousness were unnecessary it would not be an epiphenomenon, i.e. something that NECESSARILY accompanies the phenomena of thoughts. Is heat necessary to random molecular motion?
