    I see the distinction you made as weakAmadeusD

    So you've claimed.

    Which distinction?


    I would like a conceptual analysis of the difference between the three cases...AmadeusD

    I've given a brief causal history as well as an in depth enough elemental constituency.
  • Perception
    In all three cases we're experiencing the event of 'looking at an object we apprehend as a pen which will write with red ink", right?AmadeusD

    There are no red pens in hallucinations and/or dreams thereof.
  • Perception
    None. This is literally something I am asking you to address. You drew the distinction.AmadeusD

    What distinction do you think I drew?
  • Perception
    When do you actually 'see' a Red pen?
    — AmadeusD

    When 'you' have biological machinery close enough to our own.
    creativesoul

    This is unfortunately, quite unhelpful. That obtains in all three cases and provides no basis to delineate.AmadeusD

    We already drew and maintained the distinctions between seeing, hallucinating, and dreaming?

    Those still hold.

    They all include biological machinery. They do not all count as seeing a red pen. Please keep up.
  • Perception
    Given that we only call the pen 'red' by convention, can this particular difference (realistically, the proximity to the trigger (whereas dreaming is far askance)) really do much lifting?AmadeusD


    What difference are you drawing/maintaining? If it's unacceptably weak, then why mention it?

    There are very different basic elemental constituents. Red pens, while playing a causal role in all three, do not play the role of elemental constituent in all three. There are no red pens in dreams and/or hallucinations of them.
  • Perception
    cause differsAmadeusD

    Yup.

    Seeing red pens is an experience that is partially caused by red pens. Hallucinating and dreaming red pens are experiences partially caused by seeing red pens. Hallucinating and dreaming red pens are partially caused by red pens.
  • Perception
    The broader methodological point is that philosophical dichotomies such as subject/object. subjective/objective, internal/external, private/public are difficult to maintain on close examination
    — Banno
    apokrisis

    Those dichotomies cannot properly account for that which is both. Some experience consists of both subject and object, internal and external things. All talk of experience is both, public and private.

    That's the broader point that came to my mind. The inherent inadequacy of those dichotomies to be able to take sensible account of all human experience.

    What counts as the bare minimum criterion for what counts as being an experience?

    For starters, I say it must be meaningful to the creature having the experience. We must be able to say how.








    I asked what the difference was between seeing red stuff
    Reveal
    (what happens when we look at red stuff)
    , hallucinating red stuff
    Reveal
    (which never happens while looking at red stuff)
    , and dreaming red stuff,
    Reveal
    which also never happens while looking at red stuff
    .

    "Nothing" was your reply.
  • Perception


    Of course, smart ass. What we call something is not equivalent to causation.

    We know what causes seeing red. What causes hallucinations and dreams of red?
  • Perception


    What causes hallucinations of red?
  • Perception
    The percept that occurs when we hallucinate red is the percept that occurs when we dream red is the percept that optical stimulation by 620-750nm light ordinarily causes to occur.

    Or if you prefer, the neural activity that is responsible for dreaming red is the neural activity that is responsible for hallucinating red is the neural activity that optical stimulation by 620-750nm light ordinarily causes to occur.

    When this neural activity occurs when asleep we call it a dream. When this neural activity occurs when awake but not in response to optical stimulation we call it an hallucination. When this neural activity occurs when awake and in response to optical stimulation we call it a non-hallucinatory waking experience.

    So then, there is a difference between seeing red, hallucinating red, and dreaming red. Hence, if they all include "the mental percept", and yet they are distinct, then it only follows that the notion of the "mental percept" is inadequate/insufficient for explaining those differences.

    Raising the cap on taxable social security income levels would more than fix the problem. Only those who benefit the most would see a SS tax increase. Somewhere around 175K yearly.
  • Perception
    On this view you're advocating for, you're clearly stating that there is no difference between seeing, hallucinating, and dreaming.

    I didn’t say that.

    Sigh.
  • Perception
    Now the word "red" is no longer in books, on paper, spoken aloud for everyone to hear, or on our screens... it exists only in the mind.

    Perfect.

    Oh brother...
  • Perception


    Well, there are certain groupings of nerves(specific parts of the nervous system) that do different stuff than others. If certain biological structures are always active while urinating, it does not make urinating equivalent to the structures.

    That seems to apply equally to C4 fibres and pain as well as V4 and seeing red.
  • Perception


    If the biological machinery behaves in a certain way when one looks at a red pen, and yet also behaves the exact same way when there is no red pen, then we have a hallucination(malfunction).

    If the biological machinery acts as though one is looking at a red pen, but it is doing so while one is sleeping, it's causing one to dream about a red pen. Again, there is no red pen.

    Red pens are always included in seeing red pens, but they are never included in hallucinating or dreaming about them.

    Sure, the biological machinery acts the same. That's not an issue.

    Well, there we have it. Straight from the horse's mouth, so to speak. On this view you're advocating for, you're clearly stating that there is no difference between seeing, hallucinating, and dreaming. Yet, there most certainly is. This is all very odd, considering that earlier you professed one of the reasons for holding that view was because it explained hallucinations, dreams, and seeing. What you call an explanation, I would call a confusion. There are differences between seeing red, hallucinating red, and dreaming red.

    Reductio ad absurdum is adequate for rejecting the position you're arguing from/for. Equivocation is as well. Self-contradiction is also. I've neither the time, nor the inclination to show those again. You've sorely neglected to directly address those charges, in lieu of low hanging fruit.

    I think I've seen enough here. Thanks for the interesting discussion/thoughts.

    Be well.
  • Perception
    We can, and do, use the phrase "red part of the visible spectrum" to mean "620-750nm light". Pens do reflect 620-750nm light, and so we can, and do, say that pens reflect the red part of the visible spectrum of light.Michael

    Then you're equivocating. Earlier you've put forth the claim that light has no color. The visible spectrum is light. Red is a color.

    Color, according to you, is a mental percept... nothing more. The visible spectrum is not.
  • Perception


    Sure seeing a red pen is not equivalent to a red pen. Moreover, seeing red is not equivalent to red. That's a problem as well.
  • Perception
    If red is just a part of the light spectrum (x to x frequencies) that's fineAmadeusD

    Well. If red is part of the light spectrum, and certain things reflect that range, and we're capable of detecting that range, that's how we see red things. They would be reflecting that range even if we were not looking. That seems a problem for the view I've been reading from Michael, and I presumed(perhaps mistakenly?) you're in agreement with his view as shared here in this thread.

    If red is part of the light spectrum, and red is a color, then light has/is color. That's a problem for Michael.
  • Perception
    We can, and do, use the phrase "red part of the visible spectrum" to mean "620-750nm light". Pens do reflect 620-750nm light, and so we can, and do, say that pens reflect the red part of the visible spectrum of light.

    But this isn't our ordinary conception of the colour red. Our ordinary conception of the colour red is that of the mental percept that 620-750nm light ordinarily causes to occur. This is how we can make sense of coloured dreams and hallucinations, of synesthesia, of variations in colour perception (such as the dress), and of scientific studies like this.
    Michael

    Is that the only way to make sense of those things mentioned?

    What's the difference between seeing red and the mental percept that 620-750nm light ordinarily causes to occur?
  • Perception
    my mind creates a red experience for me in response to a(in this case, a very specific) frequency of light reflected of a cooked sugar surface. It isn't in the Skittle.AmadeusD

    So, you and Michael are claiming that the properties/features/physical characteristics regardng the surface layer of red pens cause us to see color, and the color is nothing more than a mental event/phenomena.

    Things reflecting certain ranges of the visible spectrum cause us to see red, or green, or violet. That seeing of color, according to you, is nothing but a mental phenomena.

    Rather than claim that the pen is reflecting the red part of the visible spectrum causing us to see red, you'd rather say that there is no red part of the visible spectrum, rather there are certain ranges that cause us to see red.

    Is that about right?
  • Perception
    My point about the scanner is that it cannot detect colour.AmadeusD

    It detects what we've named "red", despite not having mental events.
  • Perception


    Just off the cuff absurd conclusions following from the idea that color is nothing more than a mental/psychological event.
  • Perception
    There is no red in the spectrum.AmadeusD

    Not a Skittles fan, huh? Taste the rainbow, except the rainbow has no colors.
  • Perception
    The range we've named "red" cause us to see red, but there is no red in the range.

    Excellent.
  • Perception
    Yeah. Seems there are some rather absurd conclusions lurking hereabouts.
  • Perception
    Prisms do not refract the light into the visible spectrum, or the visible spectrum is colorless.
  • Perception
    Rainbows have no color.
  • Perception
    "Mental percept"

    Occam's razor.

    What's being explained by the invocation of "mental percept" that cannot be explained without it?
  • Perception


    Frequencies of light are not color... according to those I'm arguing against.
  • Perception
    Did science abandon the visible spectrum? The infrared? The ultraviolet?

    :brow:

    There's something awefully funny going on in here.
  • Perception
    Science has led to automation capable of color matching nearly any surface presented to its scanner. It does so to near perfection. Funny how that can happen if color is psychological/mental and nothing more.

    Automation can mix physical pigments to perfectly match the color sample.

    The scanner cannot see/detect/perceive color if color is nothing more than neural/psychological events.
  • Perception
    Sounds peaceful to me. The wrong cat, huh? I've been fortunate enough to have never owned the wrong one. He no like you, or you no like him?

    Cheers. That's what I do for living. Fortunate enough to be able to choose something I love to do. I am living well in that regard.

    I hope you are as well!
