    One mistake I see people making is that philosophical theories don't change the semantic meaning of everyday language. They change the underlying models we use to frame our understanding of things.

    Suppose you are an indirect realist conversing with a child who is a naive realist (all of our natural starting points, I think). The child says "I see a tree", and you understand immediately, there is no confusion. You don't mentally mistake him for a indirect realist, nor do you have to mentally translate what he says into indirect realist terms. That is because the semantic content of the sentence "I see a tree" remains constant no matter what philosophy of perception you hold.

    Why do you and I want to say, and why do some phenomenologists say, that the things we perceive present themselves to us? I feel I’m missing something obvious.

    What even is that way of speaking? :chin:
    Jamal

    I think this idea of objects "presenting" is primordial. Aristotle systematized it with his ideas of act and potency, but in a less reified form it could be construed as a kind of fundamental attraction, resonance, or eros. For Aristotle a central theme of science and philosophy was movement or change. For example, what moves a plant? Sunshine, rain, soil, etc. What moves an animal? Primarily hunger and the sexual drive (both of which are forms of desire), and any objects which present themselves as that which will satisfy these desires. What moves a human being beyond these vegetative and animal forms of motion? Forms of reason, including inference, suspicion, suggestion, etc.

    For instance, when a female peacock encounters a "peacocking" male, is it more apparent that the male is exerting an attracting force on the female, or that the female is exercising agency in moving towards the male? I think the more obvious phenomenon is the magnetism of the male, and, generalizing, the magnetism of objects. We might say that this is the primacy of the "being acted upon," as opposed to the "acting upon." Movement never occurs except for that which beckons.

    So Aristotle simply took this scheme of passivity and incorporated humans: if a thing is defined by the manner in which it moves/changes, and an animal moves in an animal way, then a human moves in this same animal way, but with the additional infusion of reason (i.e. a human is defined as a rational animal, one whose movements require the additional explanatory element which we call 'reason'). This is not implausible, for just as the eye does not move itself but is rather moved by what attracts or "catches" it, such as the male peacock, so too does the mind not move itself but is rather moved by what attracts it qua rationality (e.g. coherence, cogency, utility, explanatory value, etc.).

    Now of course there is an antinomy when it comes to humans, but our age is so suffused in notions of agency that we fail to see the obviousness of the "presenting" idea. If we must choose between the agency of the subject's choosing and the agency of the object's attracting, which is more apparent? Contemporary man says, "Why hold to the primacy of the object's attracting or presenting?" Ancient man says, "Why hold to the primacy of the subject's choosing?" In the modern world we have refashioned our situation such that the prima facie answer shifts, and yet the older and more primordial view is always glimmering in the background.

    A great essay on this topic is Owen Barfield's, "The Harp and the Camera," where he contrasts these two different ways of human being.

    At least on the forum, productive discussions of direct vs indirect realism tend to require pinning down where the disagreement is between disputants.fdrake

    As I understand it (which is not very much), direct realists use the words "see" or "perceive" in a conventional manner, taking into account the filter that is the human perceptory apparatus in the act of "seeing" an object. On the other hand, indirect realists, who are unsatisfied with our human all too human perceptory filter, use the word "see" or "perceive" in an unconventional manner that eschews our human filter, demanding a God's-eye-view or view from nowhere in their use of the word "see" or "perceive", all the while pointing out that we have a human filter that colours the real objects of our perceptions.

    Not to prejudge the issue, but indirect realists are misusing the language.

    The direct realist would say "I see what appears to be a bent stick, but I know it's really pretty straight, because I took it out of the water".Janus

    I would have thought that an Indirect Realist would also have said "I see what appears to be a bent stick".

    The Merriam Webster Dictionary lists 23 different meanings of the word "see", including "to perceive by the eye" and "to imagine as a possibility". The expression "I see what appears to be" is quite complex. On the one hand it shows the poetic beauty of language but on the other hand it can be open to misinterpretation.

    It depends on the meaning of "Direct Realism". Is there an authoritative definition of Direct Realism?

    As a start, there is the SEP article The Problem of Perception

    In 3.2.6, the article distinguishes between a causal form of direct realism and a phenomenological form of direct realism (PDR), something the Intentionalists are sympathetic to.

    There is also Semantic Direct Realism (SDR).

    Is there in fact any substantive difference between PDR and Indirect Realism?

    I don't need anybody to jump through hoops to know what I'm saying when I say "I can see my house from here".flannel jesus

    The Indirect Realist is in part pointing out that language is more figurative than literal.

    If one was being literal, the speaker would have said: "I can see the front wall of a house that I know for several reasons is mine, such as there is a pine tree in the front garden, not in the sense that I own the freehold of the house but rather rent out a room from the landlord, and when I say I see my house I don't mean that I can see the back of the house, or any of the rooms inside the house, but only that part of the front wall not obscured by the pine tree."

    This would obviously make language unworkable, so the speaker reduces the literal sentence to the figurative sentence "I can see my house".

    The average person knows what this means, because the average person knows about the figurative use of language.

    There is no such demand. To make it would be foolish as perception is inherently indirect, it necessarily involves construction of a representation. God presumably would see some sort of syntheses of every representation possible of the house, Us mere mortals can only see it as we are built to. As @flannel jesus says, this is not a problem, its just how perception works.

    None of this touches on the semantics of the word "see", which remains the same in any case.

    Yes, you did say that, and I don't know why. If I asked 100 indirect realists if they demand that, I don't think a single one would say yes.

    The conversation between direct realism and indirect realism isn't about "demands", I don't think the word "demand" is helping with clarity here.

    Are dogs and cats indirect realists or direct realists?Corvus

    According to the SEP article on Sense Data:
    “Sense data”, or “sense datum” in the singular, is a technical term in philosophy that means “what is given to sense”. Sense data constitute what we, as perceiving subjects, are directly aware of in perceptual experience, prior to cognitive acts such as inferring, judging, or affirming that such-and-such objects or properties are present. In vision, sense data are typically described as patches exhibiting colours and shapes.

    Presumably, when a cat sees a mouse, photons of light have travelled from the mouse to the cat, and the cat sees photons of light.

    The photons of light are sense data, in that "what is given to sense".

    How can the cat see the mouse in the absence of these sense data. How can the cat see the mouse in the absence of any photons of light travelling from the mouse to the cat?

    Yes, this was my point. You see a bright dot, and first you don't know what it is. It is a bright dot, which has red colour. But when you learn about it, and the book tells you it is a star called Mars. You know what it is. It is the planet Mars. Next time when you see it, you see the same bright dot in the sky, and your reasoning tells you it is the planet Mars.

    If you then analyse how you end up getting the perception of the bright dot in the sky, and explain photons of light travelling into your eyes, then it is the low level explanation using the concept of light travel. You are using the scientific reasoning to the way how the perception works.

    It is just different level of the explanations on the perception. It is not different mechanisms of the perception.

    Metaphorically one could even say, Mars was whispering to me tonight.

    Saying Mars is photon of lights, and the mouse is also photon of light sounds meaningless and confused.

    Bottom line is that sense data is not transmitted by the objects. Sense data is the product of reasoning on the existence and nature of the object by the mind.

    There is a mouse and photons of light travel from it to a cat. It takes time for light to travel a distance.

    By the time the cat sees the mouse, the mouse has unfortunately died, and yet the cat still sees the mouse.

    There is still the body of the dead mouse in the external world where it died. The mouse died biologically of course, but the dead body still exists. No problem for the cat to see the dead body of the mouse.

    I am not sure if this is really the case. That's what you seem to think. But we don't know what the cat thinks about the actual situation. Your assertion has little ground explaining the reality of the case here. This is something that no one can verify, unless he could have a discussion with the cat about it.

    It still sounds the account has nothing to do with "Indirectness" in perception. If there was no reasoning applied to the shapes and colour, you would have no idea what it is. You may have said, it is an UFO in the sky looking down at you. You wouldn't have said "I see Mars." when it was Mars you were seeing.

    Again bottom line is that, Mars has far more property than photon of light. It is a physical object in the sky with the mass and weight, weather and rocks and soils etc etc. It is not just a patch of photons of light.

    I would have thought one would be smart enough to infer the existence of Mars when seeing the bright red dot in the sky based on the inductive reason that things keep exist as it does even if it takes time for the light travel to the observer's eyes.

    It would be unreasonable to conclude that Mars doesn't exist just because it takes time for the photons of light to arrive at one's eyes.
