This is my first posting to Great Debates. Please accept my apologies if I don’t quite “get” how it works.
I have found it useful to do two things that not everyone cares for. First, I assert-as-true various posits without prefacing them with “IMHO” or equivalent; please feel free to make the needed insertion as a default mode. Second, I notice I tend to make more use of “what if” styles of argumentation than do others: my tendency is try try to establish what is possible before worrying too much about what is actual.
Now then. The essence of this thread is not, specifically, about Wittgenstein and beetles, but a certain core issue raised by the following question: “If all I can ever possibly be aware of is some set of entities of type ‘M,’ where ‘M’ is by definition characterized by the attribute ‘available only to one’s own observation: as in the supposed private content of one’s own mental experience;’ and if my use of (an uttered, “public”) language presupposes the knowable existence of a supra-self world of particular referent-objects upon which the meanings of my utterances are founded; how do I justify my belief that language communication is possible, or even conceivable, given this apparent contradiction?”
To really speak (=with meaning and intent) is already to believe that another might possibly hear and understand. But by the standard model, for a linguistic unit to have meaning in a “language community” is (in effect) for the members of that community to have been able to engage in a shared experience (such as: seeing someone point to a tree) and to have discerned in that experience some element that is taken to be the referent-object of the referring sign (the sound or symbol).
But if I can only perceive my own mental furnishings, and you can only perceive your own mental furnishings, it is logically possible that what I took to be a shared experience–two minds with a common thought, so to speak–was no such thing. Even assuming what one (perhaps) has no right to assume–that “you” in fact exist at all as an independent center of perception, and that some sort of event took place “in” your mind simultaneous with an event in mine, and that we both somehow intended that said paired events would produce the definition of a certain referring sign–I have no reason to presume that your experience was IN ANY WAY comparable to my own.
That last statement puts things rather starkly. I am not saying that “my green may be perceived by you as what I would consider a different shade.” I am not saying “my green may be perceived by you as what I would consider red.” I am AT MINIMUM saying, “my green may not even be perceived by you as what I would consider a VISUAL EXPERIENCE.” It is “an experience” (for the uninteresting reason that the key term means little more than “a something known by a mind”). But (like the result of division by zero) it is literally incommensurable, one self to another self. What is put before your mind when you claim to be “seeing green” cannot be shown to be ANYTHING LIKE any experience of mine. {…what is seeing like for a stone? for the Trojan War? for Euclid’s Fifth, or Beethoven’s? I do not yet know that what I call “that other person over there” has a “self,” any more than I know that these objects have one…}
But why accept that my belief in other persons, other minds, the possibility of communication, an external world, etc., require “proof”? If I find that I am thinking “X”, I do not need to “prove” that it is indeed “X” of which I think. “X” is simply the name, the particular experienced twinge of designation, that is defined by my mind’s perception-in-the-moment.
You object: But how do I know that “X” might not designate something different tomorrow, that it might not come unstuck in my mind? I answer: What is the meaning of “different” in such a circumstance, given that it is my current connection of “X” with its referent-object that provides “X” its incorrigible definition? Two occasions of use–even regarding the selfsame individual person–can not be “objectively compared.” There is neither difference nor sameness. {…nor is equality blue or green, or a symphony right-handed or left…}
My belief in an objective world, in YOU, has the status of an axiom, not something deduced or derivative. Far from being questionable, such things are the essence of truth itself: I verify the existence of such items immediately and directly, by knowing them. (Likewise, I verify that my present experience exists merely by having it.)
And yet the other part–the self-subjectivity of my experience, of my thought of anything–is also axiomatic. By no twisting and turning can I conceive it impossible that, e.g., “my green is incommensurable to your green.” I cannot convert the opposite proposition into a necessity, for I can always conceive of its violation. (I can even conceive that some supposed “isomorphic pattern” might be “like” one thing in my mind, another thing in yours–or, better, simply that I must deny that they are commensurate at all.)
How can I close the gap?
I have come up with this notion.
For every thing-that-there-is, there are two aspects. The first is its logical essence, its identity or “whatness.” It is NOT atomistic, not componential: it is the unial referent-object no matter what the reference may be (to an individual, or a heap, or a group, etc.), and it constitutes the meaning of the reference.
Indeed, a “meaning” becomes a metaphysical object, a real existent in its own right. To know a meaning is to bring about a certain relation between self and meaning-object: AS IF to place the object before the mind.
Every meaning-object transcends the borders of self-subjectivity. Anyone and everyone can know it. When I communicate (with complete success) a meaning to you, you perceive the very same meaning-object as I do. When I teach you the meaning of a word, I am guiding you into a position to “see” something that I already am seeing.
Meanings are thus objective, independent individuals, not entities somehow generated by my mind or your mind. We don’t make them: we find them.
And at the same time–and here there is less to say–in the moment of mental perception, the objective logical identity is clothed in a purely subjective form, a “way it seems” that can neither be analyzed nor communicated. It formally exists; but it “exists to me,” a mode of being we can allude to only with difficulty, and can never divorce from its objective other half.
It is impossible, unintelligible, to “experience the way-of-seeming of another self”–or even one’s own self at another time. The momentary seemings replace one another and are gone, never to return; and part of the experience of the “seeming” is this endless flux, this entering-and-leaving, this passage.
So.
