Just as any science (or even epistemology) is.
Just as your pet’s life is unliveable to my pet or your PC’s computations are uncomputable to my PC, and yet we are not debating the scientific explanations and conclusions of biology and computation. Language is the protocol by which we share our experiences (ie. temporal brain configurations). The heterophenomenological method is really no less scientific in its demonstrations than other fields on which the health of you and your loved ones depend.
…or, at least, a mode of explanation even if the details are still uncertain, like modern evolutionary biology. To tend towards rejection of both natural and supernatural modes is arguably no ‘decision’ at all.
I disagree: sometimes it is, sometimes it isn’t. After all, a cause always does correlate (but not necessarily vice versa) - otherwise, it wouldn’t be the cause! In the computer case, one is entirely justified in believing that particular correlative factor (the activity) to be the cause, yes?
And Christmas presents cannot tell you whether Santa Claus is a cause or a result of what your parents tell you about their origin. I’m not refuting Rama - I’m just reductio-ing the same valid reasoning to situations which are clearly absurdans in everyday life. We do not hold every possibility concurrently, but dismiss extraordinary or supernatural causes all the time. Some people haven’t yet done this for this particular experience/neural activity link, even though they clearly do when considering, say, the link between ‘strange’ experience and LSD, or strange experience and altitude, g forces, magnetic fields or minor strokes. I’d suggest the observed activity does suggest quite a lot if you set some stock by the general principle of parsimony.
Which is very scientifically interesting in itself. Of course I’m not saying the ghost is ‘real’, just as I don’t say the God is ‘real’. But if there is clearly some heterophenomenon there (ie. lots of sober sceptics say they feel weird), that is a datum requiring an explanation: I still wouldn’t require most people to feel weird before it piqued my curiosity, only a number who had never had such feelings before anywhere else.
