I thank @Andy and @Wayfarer for inspiring me to look more into Heisenberg’s philosophy. I found a forward by Bitbol on a book about this here.
I react to some quotes.
For, according to Kant, synthesis represents “the act of putting different representations with one another, and of comprising their manifoldness in one cognition” and it is the resulting unity of phenomena in one cognition that plays the role of an object.
As I see this, we enact this synthesis automatically, primarily as “one” does, but presumably within the vague constraints of our biology. Culture is like “software” constrained by biological “hardware.”
Is this a synthesis of re-presentations ? Yes and no. Because I perceive the “same” object yet again, automatically synthesizing two or more perceptions, the presentation of the object now is indeed a re-presentation.
But is my perception a mediating representation as a not-the-object internal mind-stuff icon that is between me and the “true” object ? Does the perceived object block my view of the true object ?
My own TLDR answer is “no.” A perception is not a second internal object that hides the true object from me. The “user interface icon” story tells me that the icon is my friend. It “translates” the true object into the right kind of second internal object. Trapped in the pineal gland, I at least get an icon on my personal private screen that helps me steer my meatbot through a “radically external world.”
The consistent internal icon theorist confesses that my perception of the meatbot in the mirror is actually another icon. The “radically external world” is the output of a delicate inference. “Presumably” there is something like the perceived meatbot out there in this inferred external world.
Brains as perceived are also internal icons. “Presumably” something like perceived brains is responsible for the translation of external world events into events on the icon screen like perceived meatbots and perceived brains.
I hope I’ve made a case that representation as internal mediation is at least a daring hypothesis and far from obviously plausible.
On the other hand, we can and do thematize individual perceptions. The signs we use to discuss them are not used like the signs we use to discuss the perceived objects.
Mach understood this. He used the neutral term “element” for a portion of what we might call the “phenomenal field.”
In my view, we are not automatically talking about a neutral monism here. We are not necessarily talking about a single “pre-stuff” that all things are made of.
I think the best reading of this “neutrality” is pragmatic. If I am doing psychology or am just testing someone’s vision, then I thematize the isolated perception. When I ask Joe what he sees, I am interested in Joe’s eyes or brain and not the Joe-perceived object. You might say that I take the object for granted here as not my focus. Joe is my focus. I am synthesizing Joe’s perceptual reports in the pragmatic context of understanding Joe’s nervous system in relation to the world.
But the same Joe might be recording a measurement. Now what Joe sees is taken to tell us about the seen object. I take for granted that Joe is a “generic” observer. I want Joe to be generic in the sense of relatively unbiased. I look at the object through Joe. Joe’s report functions for us as a “quasi-perception.” The cry “is” the eagle to the degree that we enact this copula. We believe the eyewitness about the color of the defendant’s car, and this convinces us to find him guilty, aware of the mandated death sentence. We put a man to death because of a sound some witness made in the courtroom.
Yet the cry is not “literally” the eagle, and the perception is not “literally” the object. I read this “literality” in terms of the neutrality mentioned above.
The “phenomenal field” ( “worldface” ) is structured by what Gadamer calls “linguisticality.” The “elements” are “neutral” because we rapidly transform our sense of what is relevant. The quality that “was” the rose is now an entity for psychology rather than the florist.
Now for the issue of “monism.” I go back to Plato. We can think of the phenomenal field as an articulated qualitative continuum. We might want to use “quality” for the “basic stuff” that is always already interpreted categorically. The “neutrality” of this “quality” is just our skill at swiftly reorganizing the “field of quality” in response to changes in that “field.”
But we don’t want to reify this quality. You might say that we already have, simply by pointing at it with a noun. Of course I think the use of a noun tends to make this pointing difficult. The quality is “there” and basically it just “is.” This “is-ness” is not a stuff but the is-ness of any and every kind of stuff.
This “stuff” is part of our “linguistically.” The world is always already “intelligible.” Objects are “generalized signs” in the sense of automatic “syntheses” of perceptions that can be isolated but usually are not isolated. The reification of “isness” or “quality” is tempting here. In practical life we worry about how different kinds of things are related. So ontology is approached like a cosmic chemistry.
Talk of “being” or “quality” comes off like talk of the “water” that Thales said everything is “made of.” But in this case we are digging below the “made of” framework. To me we are digging for a deep and stupidly simple structure, which is basically already in Kant, and can be traced back much further if we read Plato and Heraclitus phenomenologically.
The object “as such” is a temporal interpersonal synthesis. The “unity” of the object is “discrete” or “digital.” The object “counts as one.” But the object is there as that particular unity in terms of “quality.”
So the world is (a coherent system ) of interpersonal chunks of quality with temporal depth. Note that I am including my usual use of “presence” in the use of “quality” here.
The object is “there” as this “chunked quality.”
