I would like to say "separately" but this is known to be false, for instance, when it comes to taste and smell -- we think there ought to be some analogy, or even homology, between the different impressions. That is, the look of cut grass should be to vision as the scent of cut grass is to smell as the texture of cut grass is to feel, something like that. — Srap Tasmaner
YES. Reid was reacting to Locke - I think - and replying to Locke that primary qualities do not resemble anything in the object.
We feel the effects of the object, but not in a resemblance manner.
It feels as if there should be a consistency between our separate impressions, but there isn't.
Reid actually wrote much of his works as an attack on Hume, he was Hume's fiercest critic at the time. But they got along well, no bad blood between them.
We know the connection can be explained, grass being what it is means it looks a certain way and smells a certain way when it's just been cut, and we can associate those impressions, but that association can't help but seem somewhat arbitrary. — Srap Tasmaner
Again yes. Great. It doesn't seem arbitrary, but in some sense they are.
The look and feel and taste of that object to this person are supposed to be abstractions, in a sense, aspects of an interaction between that single object and this single subject. But it doesn't feel like that; it feels like a particular look arbitrarily associated with a particular texture and a particular scent, and so on. — Srap Tasmaner
You explain this better than me. We imbue object with permanence that they don't need to have. One minute we see a lawn, we close our eyes for a second, and we say it's the same lawn. But it isn't actually, things are changing all the time. So this uniformity is quite interesting.
But perhaps our notion of "single object" is extremely misleading, which seems to be the case.
Should we infer that everything about the interaction of that object and this subject is assembled somehow, maybe that the object is just a sort of bundle of impressions, a bundle we assemble? Maybe we also conclude that we are such a bundle. That's Hume's word, I guess, but I'm not trying to insist that there is no structure here, only that there is some assembly required to get a subject and an object. — Srap Tasmaner
It's a good question. I think that an object just is an instantiation of properties, but I also believe that something in nature holds these properties together. We do that to objects too. But it would be really weird if nothing but us binded objects together. I mean, what's to stop us from
thinking a river dry?
As for us, it's much harder to say. In a sense yes, we are instantiations of properties, but without an innate structure we could not be able to discern anything. So I suspect there is a rigid inner nature that orders ourselves and parts of the world.
Most people, I'd guess, will think there's something terribly foolish about expecting any kind of similarity between the "reports" of our various senses, but I'd much rather ask this very strange question and get an actual answer for why we shouldn't expect it. — Srap Tasmaner
Sure. This is quite speculative stuff.
The only reason I can offer off the top of my head, is that we tend to like patterns and ordering stuff, we do this all the time, practically involuntarily. But once we begin to isolate what seems to be a coherent picture, obvious things become problematic. Our common sense picture of the world turns out to be an extremely elaborate construction, which we take for granted.
You understand the problem rather well and it's puzzling for some.
