There are some from my own school of thought who could call this exchange "a fruitless endeavor," but I do not agree with this, and this is why: it is insufficient to prejudice the accuracy of one's position merely because one has convictions as to the nature of its truth. I reject this, I believe philosophy is best served as honest and diligent minds come into collision with each other. Further, those who say this, not putting forth the effort to defend their own views, are in danger of forfeiting truth to the victory of error. (Of course, this assumes their views are true). It is clear to me that what is required of serious thinkers is not merely to validate the cravings of their own egos, or to bask in their convictions, but to search out the nature of truth, even if its comprehension causes them the greatest psychological distress. It is hard for me to respect thinkers that are not willing to subject their ideas to coarse criticism. This does not mean one should apply themselves to every contrarian under the sun, but that qualitative objections should be discerned, sought out, and engaged. It greatly saddens me that so many dialectical thinkers have retreated to the Ivory Tower of theory. These thinkers do not fail to write books proclaiming the formation of their ideas, but when it comes to defending them, they fly off and hide away or dismiss the seriousness of their opponent's objections through the sheer arrogance of their convictions. Not I dear reader, I will do my best to apply thought where it deserves to be applied. I believe there are few things so valuable to the thinker than the resistance of other minds.

The first distinction I should like to make is that being is an actual, concrete thing, not a mere concept or word. Words are objects that we create in order to make sense of being. We do not discover them, unless by "discover" one is talking about cultural integration.
"Each material thing is a particular, an individual with a form proper to itself. This form is distinct from the essence of the thing, which is the form which human beings know in abstraction, because it consists of accidentals, whereas the essence does not." - Metaphysician Undercover
Isn't it actually the case that no material thing is a particular? You are in fact the one assigning this abstract identity to the object. Even the concept "particular" is not itself particular. Diversity and movement is found everywhere in being.
"Hegel argues that these three concepts [particular, individual, universal], though they seem quite distinct, are intimately bound up with each other. The understanding, however, does not see this and holds the three strictly separated. The understanding sees universals as externally related to particulars. In its extreme form, this may issue in an ontological separation between them, as in Plato’s philosophy, where universals or ‘forms’ are held to exist in a different reality altogether separate from their particular exemplars. Hegel rejects any such approach, and shows how in a real sense it is quite impossible to think the universal, particular, and individual apart from each other. For instance, if the universal is thought to be absolutely separate from individuals, and unique in its own right, then isn’t the universal an individual? Further, if an individual is understood as absolutely separate from universals, doesn’t it become an empty abstraction (i.e., a kind of universal) without specific quality? Hegel argues that the concepts of universal, particular and individual mutually determine one another." The Hegel Dictionary, Glenn Alexander Magee, Continuum International Publishing Group p.255
"The essence of a thing is not concealed at all, nor does it abide in the thing, it is the form which exists within the human abstraction, what the human mind apprehends and determines as the essential properties of the thing." -- Metaphysician Undercover
It seems to me this is the crux of everything you are saying. How can you say the essence of a thing "does not abide in the thing," and then claim to "apprehend" and "determine" it from the thing? Further, it seems the way you make use of these determinations, extracted images, I will not yet call them "properties," is to wield them as totalities and finalities against the movement and diversity of being. This seems exceedingly problematic to me, but there is more... what the mind apprehends is precisely the immediacy of an object, unless one goes beyond this mere apprehension (which takes one beyond bare identity) one cannot inform essence with totality from the narrow category of identity. Here you are trying to smuggle in content that cannot be furnished by bare identity alone. The fact that you are doing this, and that you must do this, only stands to demonstrate the accuracy of Hegel's critique of Aristotle.
"What is concealed is the independent "form" of the thing, complete with the accidentals which the human being does not necessarily perceive." --Metaphysician Undercover
This seems to contradict your previous premise, when you said "the essence of a thing is not concealed," and while I note the use of a new term to overcome the limitations of your identity position ("accidentals"), I would also note that the actual concretion of what you are doing here seems to contradict your description. I think this is the part that really matters, I think it's the part that exposes the technique of your idealism, which appears to me as a form of sophistry. It seems you are trying to walk two roads at once in an attempt to retain the appearance of consistency for your formal position on identity, but when we actually examine the concrete process of your determination and formation, we find that it negates your description of identity. What you are actually doing, which is to say, what you must do, in order to furnish being with adequate content, forces you to go beyond the so-called law of identity.
"... formal logic deals with essences, not with actual things. But dialectics is not formal logic. How do you suppose that a person might create useful abstract categories without an appropriate understanding of reality? Creation of suitable abstract categories can only follow from a comprehension of reality." --Metaphysician Undercover
The point of dialectics is that you cannot arrive at an accurate essence (understanding of reality) through identity, but must make use of unity and difference, these not only negate the narrow Aristotelian formation of identity, but go beyond it. Just because one produces a formalism, through the method which you are here defending, doesn't make it accurate or comprehensive. One could in fact understand reality in such a way that they extract error from it, thus leading to an erroneous formalism. That is to say, a comprehension of reality can only follow from a dialectical process.
"...if we reject the law of identity there are consequences which need to be respected. Initially, the assumption that there are particular, determinate individuals, beings or objects, in the real, or actual world, is unsubstantiated, unsupported and unjustified." --Metaphysician Undercover
Here your idealism shines through with vibrant colors. It is not a matter of "rejecting," I think this might be the problem in your characterization, it is a matter of incompletion, a lack of totality, Hegel demonstrates that the principle, as Aristotle forms it, is neither conscious nor consistent with itself.
Perhaps the clearest formation of the refutation of the principle of identity presented by Hegel, is when he notes that A=A requires three
different symbols linked in
unity to even form the syllogism. Merely within the symbolic logic you have the diversity of Unity, Difference and Identity, which are all required and presupposed in order to make sense of identity. There is no identity without them, where there is identity, there you already have the negation of Unity and Difference.
You claim that if the Aristotelian formation is rejected that we cannot make sense of objects in reality, but this presupposes that we actually form our concepts through the narrow prism of identity, but we don't, this is the naive idealistic assumption, it is akin to the idealist drinking his own Kool-Aid. Hegel proved that every occurrence of identity is making use of other principles, namely, unity and difference.
I am well aware of the fact that you will likely claim I am attacking a strawman of your position. If this is actually the case then my argument has not made contact with your discourse. However, I think the reason you claim this, is because the thing you are claiming is not the same as what you are doing. You are saying that I am not making contact with your position because I am not validating your
description of the process, but like Hegel, I am claiming that your actual process of identity is in tension with your formal description.
