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

Either naive realism is true or naive realism is false. It's a simple dichotomy. — Michael
I meant better options than just indirect realism(indirect perception) as compared/contrasted to naive realism. There are more choices than just indirect realism that presuppose all components of all experience is/are located in the brain. — creativesoul
Naïve realism is a theory in the philosophy of perception: primarily, the philosophy of vision. Historically, the term was used to name a variant of “direct realism,” which claimed (1) that everyday material objects, such as caterpillars and cadillacs, have mind-independent existence (the “realism” part); (2) that our visual perception of these material objects is not mediated by the perception of some other entities, such as sense-data (the “direct” part); and (3) these objects possess all the features that we perceive them to have (the “naïve” part). In this, the theory contrasted with theories such as scientific direct realism (which rejected (3)), indirect realism (which rejected (2) and (3)), and phenomenalism, which rejected (1). Today, however, most philosophical theories of visual perception would endorse at least claims (1) and (2), and many would also endorse (3). In this setting, “naïve realism” has taken on a more precise use. As understood today, the naïve realist claims that, when we successfully see a tomato, that tomato is literally a constituent of that experience, such that an experience of that fundamental kind could not have occurred in the absence of that object. As naïve realism, thus understood, sees perception as fundamentally involving a relation between subjects and their environments, the position is also sometimes known as “relationalism” in the contemporary literature. Typically, today’s naïve realist will also claim that 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. On such a view, the redness that I am aware of when I look at a ripe tomato is a matter of my experience acquainting me with the tomato’s color: the redness that I am aware of in this experience just is the redness of the tomato. As such a view appears to commit its proponent to a version of claim (3) above—that for one to see an object to have a feature, the object must actually have that feature—the inheritance of the name “naïve” realism seems appropriate. As for whether there can be naïve realist theories of senses other than vision, this is an issue that awaits a more detailed exploration.
Not necessarily. I’m undecided between eliminative materialism and property dualism. — 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
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
What scientific account of the conscious 'phenomenal' character of experience allows for distal objects and their properties to be constituents? — Michael
What scientific account of ocular nature forbids seeing things that are not in the brain? — creativesoul
I don't know what you mean by "seeing things". — Michael
If the cow is in the field, then it is not in the brain. If we see the cow, then we see things that are not in the brain. The cow is one of the things we see.
What scientific account of ocular nature forbids us from seeing cows in fields? — creativesoul
...this has nothing to do with the dispute between naive and indirect realists. — Michael
Odd that all that color matching can be successfully achieved by a brainless machine. — creativesoul
This is all just hand-waving and insinuation. When you present an actual argument I'll address it. — Janus

What does our biological machinery do then, if not directly connect us to the world? Sometimes the causal chain is longer than others, but it is a direct link between the creature and the world nonetheless.
Biological machinery interacts physically with distal objects.
The indirect realist uses knowledge of how biological machinery works as ground to deny that we directly perceive distal objects. If we adhere strictly to the preferred framing of folk like Michael and perhaps yourself(?), we would have to deny any and all physical contact between cows and eyes. If we extend that criterion to other senses, we would be forced to say that physically forcing our face into a pudding pie and withdrawing it would not count as directly perceiving the pie. Even if and when our eyes were/are open. — 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
