[...] but it just demonstrates that dualism is necessary in order to properly understand the existence of individual entities. — Metaphysician Undercover
To be clear about my personal stance, the duality I uphold is other than Cartesian. It’s not easy to adequately define in a few words, but it is akin to a view of self holding within it a holistic substance that is not the self of information, be this information of the mind or of the physical. Both of the latter to me are different aspects, or manifestations, of the same substance. This holistic substance—that of a form which holds potential to be, to exist, devoid of the information by which it gains its manifest-form within time and space—I in some ways liken to the selfless being which Buddhists term Nirvana. Hence, while I personally don’t disagree with dualism, my view is not that of substance dualism in terms of a duality of information. (This, of course, is not to deny different aspects of this same substance of information.) All this to be upfront about my own dualist stance.
That stated, in the modern sense of substance, even if one were a substance dualist, there would via material identity alone be found no means of discerning between different givens of each of the two substances. One idea would be indiscernible from another due to both being of the same material identity. One physical object would be indiscernible from another physical object. Etc.
Material identity to me only makes sense due to the functionality of the individual materials addressed. For example, a wooden X is different from a metal X only in so far at the wood holds different properties of functionality from the metal.
I have to admit that I didn't understand your argument for identity from purpose. — Metaphysician Undercover
Hopefully this won’t further confuse matters: Functionality as I interpret/intend it can be readdressed as the context-specific role of the given. This context-specific role of the given is one of kinetic and potential interactions with other(s). I’m very aware that such metaphysical approach can become confusing devoid of an entire metaphysics to support it. Nevertheless, to me it’s intuitive that one rock is, in part, different from another due to its context-specific interactions, both kinetic and potential—in short, due to is context-specific role or, else stated, its functionality relative to its surroundings. One rock’s presence (even if it is statically placed) will be different from any others, for example, in terms of what its removal from the given environment would causally signify. This perspective, then, takes into account causal relations between givens, locally and globally. Still … this isn’t the place to attempt to properly justify this perspective. I’ll address more particular examples below.
I don't see this as an argument for identity, I see it as a way of defining a term. You say that an object must fulfill certain conditions before it can be called a flower, so this is to define what it means to be a flower. But I understand the act of identifying to be the inverse of this. Rather than saying what it means to be a flower (that is defining rather than identifying), we take a particular object and say what the object is, that is identifying. — Metaphysician Undercover
I’m thinking of identity in terms of discernibility: If we can discern X than we do so only with the backdrop of not-X. Any discerned X then, for me, holds identity
to us which discern; i.e., we identify X the instant we discern there being X--though we many not necessarily fully understand that which we've identified/discerned. This approach doesn’t rely upon narrative; rather it relies upon perceptions, sensations, and understandings. Hence, lesser animals can discern X from not-X as well—say, predator from not-predator, etc.—though they do not use narrative (words) to do so.
Being of this perspective, I’m not having an easy time interpreting you’re position. For instance, I can discern a broad quantity of givens at any particular moment thought I don’t use narrative to so discern all the givens that I do. Rather, I use narrative to convey that which I discern—either to myself during reasoning/thinking or, else, to others. To me then, discernibility is primary; narrative about that discerned secondary.
So from my perspective, why do you think that your definition of "flower" is more "real", or states more precisely what a flower really is than another definition? If objects don't have a real identity which is proper to themselves, how is our naming of them anything more than arbitrary? — Metaphysician Undercover
I interpret you as enquiring into the objective identity of things. My best resolution so far is to rely upon universals of psyche. This approach doesn’t create crisp thresholds between all things. For example, between when a flower bud is a flower bud and when it is a flower (a temporal distinction); or between when a heap is a heap and when it is not (a spatial distinction). What it does do is solidify X and not-X for all members of a populace … this in manners that do not always mandate an excluded middle (such as in the two examples just given).
As to what makes that discerned as flower—by us humans, by hummingbirds, by bees, etc.—more real than merely an arbitrary concept by all concerned: I would again largely found my arguments on the flower’s causal role/purpose/functionality relative to its context, as previously addressed. Hence, as I currently construe things, the role of a flower will remain
more fixed than its shape or material content. To address one of Heraclitus’s better known analogies via the just stated: one cannot step twice into the same shape or material content of a given river; yet the river as context-dependent role will nevertheless remain the same (identical over time). Clearly there’s more to the river than just context-relative purpose-form, and its context-relative purpose-form too is in flux, yet this context-relative purpose-form is what remains stable relative to ourselves as separate process-bundles. The context-relative purpose-form is the gestalt which is “the river” and not any of its parts. Though not the only element involved, it plays an integral aspect in our discerning the given river to hold an objective identity. Devoid of this, there no longer is discerned “a river” but, maybe, any number of the river’s parts—each with its own context-relative purpose-form. These context-relative purpose-form, to me, are then ontic—as ontic as any river, flower, etc. is.
On a more psychological train of thought: This context-relative purpose-form of things is something I believe we all intuitively apprehend. And, as intuitions go, they’re more sub/unconsciously reasoned than consciously reasoned.
No worries if there are disagreements. I mainly wanted to better clarify my position regarding functionality and identity.
