Best to begin at the beginning. As a matter of fact, if you had no eyes, no ears, no hands to feel, only your mind to think, you could not arrive at an understanding or form of a chair. But chairs are real things, they exist independent of the human mind, this premise is the swift destruction of your position. This is true because all that you say about the chair and its form hinges on the actual existence of a chair, coupled with your sensory ability to detect it. If you remove this premise, if you subtract the concretion of the chair and your senses, and leave only your mind, you would not arrive at an understanding of a chair. Matter is the substance of mind, remove this and there is nothing left.
"To represent the law of identity as saying that "a thing is not different from itself" is a mistaken representation, because it is to oppose different with same, and that is to give "same" a formal definition, but the law of identity associates "same" with matter." -- Metaphysician Undercover
The easy way to refute this is simply to re-ask the question, is identity different from itself? You obviously have to say no. We could try to say that identity is not saying this, but that would merely amount to a denial of its actual being. When I thought of this objection by Hegel, it crossed my mind that perhaps he was just engaging in sophistry, trying to artificially attach difference to identity. But the thing is, identity is actually saying this! Hegel is not making it up. To prove it, look what happens if you deny it, surely you will not say that identity is different from itself? This would destroy identity.
Hegel is correct, identity contains unity and difference. Back to the symbolic form:
A = A is an instance of three
different symbols. Taken together (
unity) they are said to form the law of identity. Everything you need to prove that Hegel's dialectical clarification is correct is contained right in the symbolic form. When I brought this up before your reply was as follows:
"This really does not make sense to me. "Difference and identity... [are required to make sense of]... identity"? If your wish is to put this forward as an argument against the law of identity, you need to formulate it in a coherent way. The law of identity states that a thing is the same as itself. One might represent this as A=A, but you need to bear in mind that this is what A=A represents in this instance. So I have no idea how you infer "diversity", "unity", and "difference" from "a thing is the same as itself"." -- Metaphysician Undercover
The answer is that you have three different symbols combined together in order to construct the law of identity. This is not my opinion. This was not Hegel's opinion, this is an empirical fact regarding the symbolic structure of identity. Why this structure, why not another?
One can deduce the same properties from the informal articulation: a thing is the same as itself. Here you have multiple different words combined together to construct the law, and here's the vital point, you cannot construct this law without making use of these
different terms combined in
unity.
When you try to bring in the predicate to rescue this law all you are doing is going beyond what is actually contained in the identity premise. You must admit that the predicate introduces negation. Well friend, this is not contained in Aristotle's formulation of the law. Once again, your predicate attempt would imply A = -A.
At every turn you are going beyond the premise of this law in order to rescue it from itself, the only difference is that you are claiming that all your actions are still contained within the premise of the law.
""Same" and "different" are not proper opposites when "same" is used as it is in the law of identity." -- Metaphysician Undercover
The point is not that they are opposites. Same is saying that it is not different from itself, it is also never an isolated word but requires the unity of difference to distinguish itself.
"Difference is included within same, because the same thing has a changing form, and therefore is different from one moment to the next, despite maintaining its identity as the same thing." -- Metaphysician Undercover
It does not actually maintain its identity, this is an ideal we project. But that is a different point. We are here discussing the law of identity. Difference is posited in the same instance as you posit "same." It is already contained within the concept, within the very being of sameness. This is Hegel's point. In dialectics contradiction always emerges
from being.
"This is represented as the difference between subject and predicate which I described earlier. The subject may persist as the same subject, despite having predications negated at different times. So the subject remains the same, as in same subject, despite difference being a part of it, due to changing predications, when the subject represents an object." -- Metaphysician Undercover
This is just an idealistic formulation of reality. In reality the subject is changing, but more importantly, the subject itself is not separated from difference or unity. If it was, it could not distinguish itself, could not determine itself.
"Therefore "different" is not applicable when referring to the subject itself, because difference is a feature of what is predicated." -- Metaphysician Undercover
This is false, as proven above through the symbolic form, it is already part of the subject's being.
"To represent the law of identity as saying that "a thing is not different from itself" is a mistaken representation, because it is to oppose different with same, and that is to give "same" a formal definition, but the law of identity associates "same" with matter." -- Metaphysician Undercover
It is not to oppose "different" with "same," as from the outside, it is merely to draw out what the premise already contains.
It doesn't matter what you try to say the law is doing or does, what matters is what it actually contains; what matters is whether you have to go beyond it in order to derive the value you need from it.
