Granted: all causal relationships "presuppose" a connection between cause and effect,
Yes, which is why, wary of going down the nature-of-causation rabbit hole, I couched my reply as a simple appeal to consistency: Insofar as we normally accept X method of inference as establishing causation, it can be justified in applying to the particular case at hand.
and the correlation (sorry: causation)
Ha! That suggests we have similar views on causation :-)
I was happy to read your reply on Descartes in any case. I can understand why my reply could have been read as being confused.
I’ve had lots of fun discussions with people of opposing "world views" on things like Foundationalism vs Coherentism (and other "isms"). In the end I still can’t say specifically where I land, so often enough I’ll just appeal to consistency (which..uh...I guess tips a hat towards Coherentism to some degree...though every time I go down these roads I can sort of argue for different sides. After all consistency/coherency is also a necessary feature of Foundationalism and other isms...).
Hume’s problem of induction has always been fascinating to chew over. (His Dialogues Concerning Natural Religion drew me in to philosophy more than any other book I think).
Probably even more than you, as you apparently have some restraint, I can be a bit annoying on some of the forums for my own tendency to pull things towards the philosophical.
For us mere mortals, then, some kind of non-objective language is our only option in trying to express what turns us on in an audio system.
Yup! We manage to successfully navigate through the world every day, often through just such intersubjective exchanges of information.
This is what I emphasize when trying to talk about this with the more rigid "objectivists" who will wave off even subjective descriptions of different speakers as being too unreliable. Sighted bias confounds the conclusions!
I try to point out that, yes, some level of skepticism about our perceptual inferences is warranted, but it cannot be wholly unreliable since we use this every day to successfully get out our front door, among countless other tasks, as well as relaying information from our "mere subjective sense inference" to one another. "The snow plow blocked the end of our driveway with snow again, so you’ll have to leave time to dig that out..."
So we have on one end, in our most careful empirical inquiry, we want to account for the variables of human biases. That will almost always be the path to the most reliable forms of knowledge. On the other hand, we have the day to day "knowledge" that our casual subjective perceptions are reliable enough to perform all sorts of tasks. We must therefore be able to acknowledge BOTH of these situations, and be able to work from one towards the other for consistency.
We are going to at one point encounter some fuzzy borders where justification may go one way or the other. But my solution has been an appeal to the basis of the simple heuristic most of us use much of the time, which found nice wording in Sagan’s aphorism: "Extraordinary claims require extraordinary evidence."
I already gave a nutshell account of how, for me, this plays out in vetting audio claims. The more a claim slides towards the "extraordinary" GIVEN commonly understood features of that gear (e.g. how cables work), the less plausible the claim, the more strict and careful I’d want to be in vetting that claim. The more plausible, the less need for controls in order for the claim to be taken, provisionally, at face value.
E.g. if you tell me you heard differences between two HDMI cables, I’m going to want firmer evidence than your say-so. If you tell me you heard a difference between some Spendor speakers and some MBL omnis, I can provisionally accept the claim given it’s high plausibility on well known technical grounds. This justifies both the use of objective/scientific evidence and the pragmatism of every-day exchanges of subjectively-derived information.
IMO. :-)
