The difference now is, you said “talk of what the cow is doing”, which presupposes it as an extant experience. — Mww
What do you think "constituent" means? — Michael
Something that exists in one location cannot be a constituent of something that exists in a different location. — Michael
Conscious experience occurs in the brain, distal objects exist outside the brain, — Michael
...therefore distal objects are not constituents of conscious experience.
It follows that on a naïve realist view, the veridical perceptions and hallucinations in question have a different nature: the former have mind-independent objects as constituents, and the latter do not.
[N]aïve realists hold that ... [t]he conscious visual experience you have of the oak has that very tree as a literal part. — French and Phillips 2023
when we describe what's going on when we dream and hallucinate we're describing what's happening to/in us and not what's happening elsewhere in the world. The indirect realist simply argues that the same can be true of veridical experience because veridical experience, hallucinations, and dreams are all of a common kind – mental states with phenomenal character – that differ only in their cause (which is not to say that we can't also talk about their cause). — Michael
...our perceptions are shaped by those objects. — Luke
So, distal objects are literal component parts of conscious experience; in the same sense, perhaps, that the red paint is a literal component part of a painting — Michael
For my part, the issue is that some folk think there is a need to justify that they see this text, even as they read it.
But that is a symptom of an excess of doubt. Cartesian fever. — Banno
Does sensory experience provide us with direct knowledge of distal objects and their mind-independent properties? — Michael
Odd that all that color matching can be successfully achieved by a brainless machine.
— creativesoul
It's not odd at all. We build it to measure the wavelength of light and then program it to output the word "red" if the wavelength measures 700nm.
This doesn't entail naive colour realism. — Michael
The absolute epitome of trying to ignore the issue — AmadeusD
...this has nothing to do with the dispute between naive and indirect realists. — Michael
I don't know what you mean by "seeing things". — Michael
What scientific account of the conscious 'phenomenal' character of experience allows for distal objects and their properties to be constituents? — Michael
I do not see how scientific evidence refutes 2. The emphasized part needs unpacked.
— creativesoul
The important part is this: “… where this is understood in a constitutive, rather than merely a causal, sense.”
Distal objects like cows are causally responsible for the activity in my visual cortex, and so the resulting experience, but they are not constituents of that resulting experience. — Michael
Specifically, I think that "our visual perception of these material objects is not mediated by the perception of some other entities, such as sense-data" means "the conscious 'phenomenal' character of that experience is shaped by the objects of perception and their features, where this is understood in a constitutive, rather than merely a causal, sense."
Those who call themselves non-naive direct realists seem to want to accept the first part but reject the second part, but I can't make sense of the first part except as the second part.
So the relevant considerations are whether or not these are true:
1. Everyday material objects, such as caterpillars and cadillacs, have mind-independent existence
2. The conscious “phenomenal” character of that experience is shaped by the objects of perception and their features, where this is understood in a constitutive, rather than merely a causal, sense
3. These objects possess all the features that we perceive them to have
If (1) is true and (2) true then direct realism is true (and (3) is true).
If (1) is true and (2) is false then indirect realism is true (even if (3) is true).
I think the scientific evidence supports the claim that (1) is true and that (2) and (3) are false. Therefore, I think the scientific evidence supports indirect realism. — Michael
Not necessarily. I’m undecided between eliminative materialism and property dualism. — Michael
Indirect realism as I understand it is nothing more than the rejection of naive realism,
— Michael
I think that there are better options... — creativesoul
Either naive realism is true or naive realism is false. It's a simple dichotomy. — Michael
The cow I see exists outside my head. My visual experience exists inside my head. Therefore, the cow I see isn’t a constituent of my visual experience. — Michael
Indirect realism as I understand it is nothing more than the rejection of naive realism, — Michael
Not necessarily. I’m undecided between eliminative materialism and property dualism. — Michael
I don’t understand your question. It’s like asking “what counts as a constituent of a portrait of the President if not the President the portrait is of”. — Michael
the cow I see isn’t a constituent of my visual experience.
— Michael
What counts as a constituent of seeing cows if not the cow you see? — creativesoul
the cow I see isn’t a constituent of my visual experience. — Michael
We don't directly see cows – according to the naive and indirect realist's meaning of "directly see"1 – but we do indirectly see cows.
Given that the adverb "directly" modifies the verb "see", the phrases "I directly see a cow" and "I see a cow" do not mean the same thing. The phrase "I indirectly see a cow" entails "I see a cow" and so the phrases "I do not directly see a cow" and "I see a cow" are not contradictory.
1 A directly sees B iff B is a constituent of A's visual experience. — Michael
...our ability to interpret what we perceive depends on our prior embodied experiences and conceptual repertoire. I couldn't see a duck as a duck if I had never encountered ducks before, either in person or through images. But these enabling conditions for interpretation do not stand between me and the duck when I perceive it. Rather, they are the background that allows me to make sense of my direct perceptual encounter with the duck itself. — Pierre-Normand
Experience exists within the brain, distal objects exist outside the brain, therefore distal objects do not exist within experience. — Michael
