So not sophistic enough for your taste? — Banno
Interesting way of putting it when it was your position being criticised for its sophism.
Sure you can have your own philosophical platform of "everyday commonsensicalism" where science and metaphysics just drops out of the conversation as "all us ordinary folk just agree on our language use".
But right there you are already faced with the difficulty that everyday speech in fact enshrines this odd metaphysics of a lumpen realism entwined with an equally lumpen idealism. Folk just comfortably talk about bodies with minds and minds in bodies, worlds with selves and selves in worlds.
Do you really want to shut up shop on philosophical inquiry at this everyday level and call it a day ... for everyone?
The beetle in the box is about the pragmatic limits of inquiry. But it isn't about those limits in terms of sloppy everyday commonsensicalism. It is about the hard limits imposed once counterfactually structured inquiry – Peirce's critical commonsensicalism – runs out of differences that can make a difference. Quite another kettle of epistemological fish.
So as in the case of agreeing to name red as red, despite the apparent counterfactual possibility that Bob may be "really seeing green" and Alice "really seeing blue", we can see why this possibility would come to seem an uncheckable one and thus rightly "fall out of the the conversation". There is no clear way to justify the claim one way or the other. Bob, Alice and Banno can't huddle together and compare notes in any fruitful fashion.
There is some kind of reflecting surface that has a narrowly constrained luminance property, robust under varied lighting conditions, and there are these three folk at least agreeing they would classify the perceptual experience under the one socially-constructed label. Whether the perceptual experience is really the same, and so counterfactually might not be the same, becomes irrelevant to the level at which the conversation is being conducted – the everydayness of given names to colours. Further inquiry looks blocked as counterfactuals are imaginable but not presentable.
But this is an extreme case. We can see that by how quickly things change as soon as we introduce any measurable counterfactuality at all. As in adding luminance information to the wavelength information.
You say that shade is primary red. The pure exemplar case as far as you are concerned. Bob says well it looks a tinge pink to him. And Alice says to her it looks a touch scarlet. What you see as being neither a little darker nor lighter than bang on central, they say sure, it's red. But a red that is a bit white, or a bit back. As you assert, it is not at all blue or green. But for some reason we could hope to discover, we do have a luminance disagreement that can be the subject of a discussion.
We could start checking eyeballs and optic tracts. Humans show surprising variation in their visual hardware. The colours out of two different eyes can be noticeably tinged for some. So it becomes perfectly possible to dig in deeper with the neuroscience and start accounting for that linguistic disagreement in terms of its more foundational neurocognitive basis.
Even the Hard Problemers are happy with science doing that as this is just then one of the Easy Problems science is so good at tackling.
:razz:
But if everyone agrees that the fire engine over there is primary red – or even pure pink or pure scarlet, as we get very used to naming colours where about the first thing we are presented with in life is a crayon set and the expectation we will learn to speak about these sticks of wax in socially correct fashion – then our utterances lack counterfactuality. They lack explicit dialectical structure. The path to further inquiry is blocked as we assert no difference that could make a difference. Red is red just as the chair is a chair, the dog a dog, and lasagne is what awaits on the table for lunch.
So the beetle in the box story is simply about the limits of pragmatic inquiry in general. It applies to any scientific account as science demands theories expressed in the counterfactual logic which can thus be confirmed or denied in terms of the consequences that result. Does Nature answer yes or no to the well-put hypothesis?
Consciousness is not some unique problem for science. It is as bad for particle physics when faced with the apparently possibility of there being fundamental particles with no properties at all. What can one reasonably say or do to judge such a hypothesis one way or the other. It drops out of the conversation on standard pragmatic grounds.
But here we are discussing your defence of the idea that everyday language is already quite enough for you, and thus for anyone. If ordinary folk talk about minds in heads and heads on bodies with apparently no hesitations or qualms, then that becomes the agreeable metaphysics and everyone else can shut up and bog off.
Metaphysics is booted out of philosophy. Science is respected but expected to mind its own parochial concerns. Philosophy is reserved for ... well what exactly? Logic chopping and the polemics of ethics?
So yeah. Stop fobbing people off with this trite argument that the redness of red falls out of the conversation, and thus all the counterfactually grounded explanation that leads up to the arrival at such a limit also must drop out of the conversation.
That was the part of the conversation that was in fact the large discussion worth having. It was the metaphysics and the science that had already lifted the game in an interesting way.
