I don't quite understand your question. In this simplified account of physics and physiology, when the sense receptors in John's eye detects 450nm lig...

I'm sorry but this still seems to beg the question. You just assert that Jane's organic eye counts as constituting her perceptual capacities and that ...

Why not? It is effectively a bionic eye, and you granted before that a bionic eye is no different in kind to an organic eye. There's nothing privilege...

@"Esse Quam Videri", I'll try to explain this in an even simpler way, using a very simplified account of physics and physiology. 1. The strawberry ref...

Let's assume that there are just five "things" in the world; my brain, my eye, the visor, light, and a strawberry. The strawberry "moves" the light wh...

We experience (are aware of) something when we dream, when we hallucinate, (when we have synaesthesia?), etc., and these things are not distal objects...

This is the thing I'm trying to make sense of. What does it mean, for example, for 700nm light to "succeed" as a presentation of a strawberry and 450n...

I didn't say that it's about neural states. I'm saying that phenomenal experience is neural states (or emerges from them). My concern is the relations...

Hu-wail

So this is the exact naive realism that we discussed before. A thing's appearance, e.g. it's shape, orientation, colour, smell, taste, etc. is not som...

It's not metaphor or analogy, just as "I feel pain" is not metaphor or analogy (which also doesn't require anything like a Cartesian theatre or a homu...

I'm not saying that I'm watching my own mental activity. I'm saying that the schizophrenic hears voices when his auditory cortex is active and even if...

Where in time and space is this something you dream about? Where in time and space is this something you hallucinate? Where in time and space are the ...

It's not clear to me what you mean by perception, which is probably why I don't understand what you mean by direct perception. The first quote seems t...

It doesn't necessarily involve eyes, but most of the time it does. Seeing something doesn't require looking at something, just as hearing something do...

The activation of these cortices is seeing, just as the activation of other areas of the brain is thinking and is feeling pain.

No, my position is that to see something is for the visual cortex to be active and that to hear something is for the auditory cortex to be active. Mos...

There's nothing figurative about the phrase "the schizophrenic hears voices". The problem here is that you seem to think that the verb "to hear" refer...

I suppose there are two related claims: 1. The direct object of perception is a distal object 2. The direct object of perception is a mental phenomeno...

I recall an argument from somewhere that argued something to the effect of: P1. We directly perceive a distal object only if that object exists P2. Ma...

Then let's make it even simpler. There are two wavelengths of light: 1nm and 2nm. There are two neurons in the brain responsible for colour experience...

Dreams and hallucinations can be coloured (or "have colour" if you prefer), and people with synaesthesia can see colours when listening to music. This...

I think you're confusing two different arguments. The first argument is that a scenario like the below is intelligible, and even plausible. Different ...

We probably can’t, save for perhaps opening their heads and checking to see which neural correlates are active. It stands to reason that if their visu...

You don't need to believe in non-physical mental phenomena to accept that experience is something the brain does. We see and hear things when the visu...

The phenomenal character of experience is the medium, e.g. colours, which can differ between individuals despite looking at the same object and intera...

The phenomenal character of experience; the thing that occurs when we dream, when we hallucinate, and also when we're awake and looking at real object...

On indirect perception of apples: A society of people who wear visors with sensors on the outside and a screen on the inside that displays a computer-...

I think the issue I have is that you're arguing that the traditional dispute is framed wrong whereas I think that the traditional dispute just means s...

There isn't a shared assumption of "phenomenal mirroring". There is the direct realist's claim that there is "phenomenal mirroring", because that is w...

I disagree with your assertion that we must be able to determine which group someone belongs to for there to be two different groups. A scenario like ...

What does it mean to say that senses have a "direction"? If you just mean to say that (most of) our sense receptors are situated on the outside of our...

Then we're back to what I asked in this post (which I'll repeat below), which I don't think was addressed: What's the difference between a bionic eye ...

Shape as seen or shape as felt? Because these are very different things. Studies on Molyneux's problem show that those born blind who have their sight...

Then to incite a more controversial topic: Consider that there are two subspecies of humanity such that what one sees when standing upright is what th...

So there's an interpretation of (a) such that (a) is true. However, notice that indirect realists aren't arguing that (a) is false; they are arguing t...

The skeptical worry is that the sky appears blue but might be green (or not coloured at all, because colour is a "secondary quality") and that the bal...

What do you mean by senses "pointing" outward? The physics and physiology is just nerve endings reacting to some proximal stimulus (e.g. electromagnet...

We start with the naive view that there is (usually) a match between the phenomenal character of experience and the world. The sky is blue in the exac...

No, I'm saying that it's the thing directly seen. From this we then make judgements about the world that can be correct or not (if indeed we do; much ...

As I said a few days ago, these judgements do not occur apropos of nothing. Excluding the obvious cases of mathematics and logic, it is the phenomenal...

What's the difference between a bionic eye that is "integrated into perception such that judgments are still answerable to objects through ongoing int...

So why is this not also the case for the bionic eye? It simply replaces rod and cone cells with silicon chips.

Then what is the relevant difference between these: 1. An artificial bionic eye 2. An artificial organic eye (identical to a natural eye, but grown in...

So let's amend the scenario slightly. Instead of there being a screen on the inside that outputs light towards the eyes it has wires connected directl...

The problem with this is that it makes the word "direct" in the phrase "direct perception" meaningless. This is highlighted by your assertion that the...

So here's the thing; anyone can mean anything by the words "direct" and "indirect". It is possible that direct and indirect realists each mean differe...

I was referring to the example of the people with visors on their heads, with sensors on the outside and a screen on the inside displaying a computer-...

This has it backwards. The indirect realist claim is that because a) perception is indirect b) the world might not be as it appears and so c) there ar...

All of which can happen if we are hallucinating ships. In the extreme sceptical scenario we are brains-in-a-vat. This is not to say that indirect real...
