    Then how did humans come to know chemical composition of an apple?Harry Hindu

    Experiments and building theories to test. We obviously can't see the chemical composition, or at least not without an electron microscope.

    You are now talking about the light not the apple. I asked what we were missing about the applHarry Hindu

    The color of the apple we see is the result of visible light reflecting off the surface. But that's not the only light reflecting or passing through the apple.

    How do you know that's not how perception works, unless you had access to what perception really is?Harry Hindu

    I don't know what this question means. We have access to how perception works through biology.

    You keep contradicting yourself in claiming that we can never experience things as they are, yet you make all these claims about things as they are.Harry Hindu

    I'm not, but you're taking my statements as if I'm saying we don't have access to anything about things, where I said the access was limited and creature based.

    The errors come about when we think that the perception is only about the object, and not about both the body and object.Harry Hindu

    And not just perception. There's an error of thinking that an object is some way from a "perspectiveless perspective." There is no such thing. Our perception is just another perspective. That doesn't make it "invalid" in any manner (which is usually what people jump to at this point).

    "Perspective" as in from some reference point or other. I'm not alluding to perception in that. As I said, "Our perception is just another perspective."

    Then that sounds sort of like object oriented ontology where all objects are in relation to one another which isn't exhaustive, so no object has complete access to another. That would include humans.

    I don't really know enough about object-oriented ontology, and the Heidegger it grew out of makes little sense to me, so it's difficult for me to comment on that.

    From a "perspectiveless perspective" (which means considered as they are absent being perceived) objects are commonsensically considered to simply be whatever they are (even though that being is indeterminable since to determine anything about the object is to apply a perspective). Would you say that an object being whatever it is is to be "some way"?

    Yes, the feeling of cold/heat cannot be the temperature the thermometer measures because the feeling varies between individuals and even the same individual when the thermometer does not.

    I'd just say that it's a way of talking with one another, rather than something which exists.
    — Moliere

    I don't see how that's possible. Language doesn't make us feel cold or hot. Animals and babies feel heat. It's biological. And language doesn't make a thermometer work the way it does. That's physics.

    Physics gives us an explanation which doesn't depend on feeling at all. It says temperature is the result of kinetic energy of particles.

    Thus we have an appearance of heat/cold that's biologically based, and we have the temperature reading, which is physics based. The feeling didn't tell our ancestors what temperature was, only that we should avoid things that were too cold or hot for us, and that certain things happened when it was hot (fire starting) or cold enough (water freezing). But they didn't know why.

    The skeptics thought we couldn't know, but the stoic retort, "I'm horsed", shows why it is possible to know.
    Marchesk

    My contention is directed at:

    This is why the subjective-objective divide exists, whatever conclusions we draw from such a division.Marchesk

    So my feeling and your feeling and the thermometer reading all exist. But calling these entities subjective or objective is a manner of organizing rather than a divide which also exists.

    Language does not make us feel cold or hot. Language does not give us an explanation of what the thermometer means.

    But calling our feelings subjective and the thermometer reading objective is just a manner of speaking about things which exist, rather than something which exists.

    From a "perspectiveless perspective" (which means considered as they are absent being perceived)Janus

    No, it doesn't refer to that. I made this explicit above. I'm using perspective in the sense of relations and properties from a particular point or frame of reference. The idea is that relations/properties are particular and unique from each point/frame of reference, and there's no way to be absent some point/frame of reference, which can include concatenations of points/frames of reference--those are just further frames of reference. It's not saying anything limited to persons, perceptions, etc. It's saying a general truism about ontology, relations, properties, situatedness. The idea has similarities to perspective in visual art.

    Then what exactly are you saying? Particular frames or points of reference exist only (predominately) for humans and perhaps (and if so, much more minimally as far as we know) other percipients, do they not?

    But will you still insist on saying that things do not also exist "in some way" independently of all those "frames or points of reference"? To say that they do so exist would be to consider them from a "perspectiveless perspective" would it not?

    Aren't you at all familiar with physics? Frames of reference in physics, for example, aren't referring to percipients. This isn't to suggest that I'm using the term identically to physics usage, but you should be familiar with and able to understand that usage (because it's a pretty basic idea in contemporary physics), which doesn't imply talking about a percipient.

    Exactly what I was saying is exactly what I wrote out. Which is why I wrote it out just as I did. If other words would have done the job better, I would have used those other words instead.

    So you think there is physics without percipients? Not what physics describes mind, but physics itself?

    Even what physics describes is what we observe and whether that is the same as what is, or what would be in our absence, is an open question which cannot be definitively answered.

    It sounds like you know less about physics than I do.

    I am not denying that many concepts refer to sensible entities, and hence to something that may be thought of as "extra-mental". But "frame of reference" does not refer to a sensible entity.
