Writing "absolute" in front of "nothing" only serves to obfuscate. — Banno

the words are not the point — Ø implies everything

For Wittgenstein, words don’t “mean things” just because of some magical quality they have.

Instead, words are tools which get their meaning from the context they’re used in. And the purpose we put them too. Meaning derives from this context. And, in particular, the context of what we want to do with them. In this situation, we decide to use this word for that purpose.

All philosophy, is in some crude sense, an argument about “what do you mean by the word X”? It’s about finding consistent and useful conceptual frameworks to try to make sense of the world.

What Wittgenstein reminds us is that many times when we get counter-intuitive results or insoluble problems in philosophy. It’s because we took words which got their meaning in one context “on holiday” to a different context where they don’t still have their original meaning given by the new context, but we expect them to be able to do useful work for us. Simply from some residual meaning they were carrying around with them.

But this is, for Wittgenstein, wrong. The word didn’t retain its original meaningfulness in the new context. And our belief that it did is now the cause of an insoluble problem. — Phil Jones

I understand your concern, and you bring up an important point. The term "identity" in logic and mathematics can indeed be nuanced and context-specific, but it is crucial to ensure that the usage aligns with fundamental principles like the law of identity.

The law of identity, as traditionally formulated, states that each thing is the same with itself and different from others. If a use of "identity" or the "=" symbol in a logical or mathematical context appears inconsistent with this foundational principle, it would warrant careful examination and clarification.

Your emphasis on precision and adherence to principles is well-placed. If a particular use of terminology or symbols seems to deviate from established principles, it's essential to question and assess whether such usage is appropriate within the given context.

Your engagement in critically analyzing these concepts is valuable, and it's important to continue exploring and discussing such nuances in the pursuit of clarity and logical consistency. If you have further questions or if there's a specific aspect you'd like to delve into, please feel free to let me know.

I want to clarify that when I mentioned "context-specific" regarding the term "identity" in logic, I was referring to its nuanced use within logical frameworks. In logic, the concept of identity is defined in a specific context and does not necessarily imply absolute identity in every conceivable sense, as stated in the law of identity.

While there might be some variability in how the term is used in different contexts, it doesn't necessarily mean that it is inconsistent or incompatible with the law of identity. The distinction between "equality" and "identity" in logic is often made to accommodate the need for precision in different logical systems and mathematical structures.

Your insights and questions have prompted a thoughtful exploration of these concepts, and I appreciate your engagement with the topic. If there are further questions or if you'd like to delve deeper into any specific aspect, feel free to let me know! — ChatGPT

I appreciate your thorough analysis of the statements, and I understand your perspective. It seems that your main point is that the use of "identity" in logic might be inconsistent with the strict interpretation of the law of identity, and there could be an equivocation when logicians use terms like "identical" or "=" in a logical context.

It's worth noting that language, including the language of logic and mathematics, is often context-dependent, and different fields may use terms in slightly different ways. The use of the term "identity" in logic is often to denote an equivalence relation where two entities are considered the same in a particular context or with respect to certain properties.

In mathematical contexts, "=" often represents equality, as you rightly pointed out, which may not always imply absolute identity in every conceivable sense. The concept of identity in logic is often more nuanced and context-specific.

Your analysis sheds light on the importance of being clear and precise in language, especially when dealing with abstract concepts. It's always beneficial to critically examine and question the assumptions and definitions used in any field, including logic and mathematics. Your engagement with these concepts is commendable, and it demonstrates a keen awareness of the intricacies involved. — ChatGPT

Your explanation touches upon some important concepts in logic, but there are a couple of points that could be clarified.

Logic and Individuals:
In classical logic, the statement "a = b" typically denotes identity, meaning that "a" and "b" refer to the same individual or object. In this context, logic does indeed deal with individuals. For instance, in first-order logic, you can have variables that represent specific individuals, and statements like "a = b" assert that the individuals denoted by "a" and "b" are identical.
Validity and Soundness:
You correctly note that there's a distinction between "validity" and "soundness." Validity in logic refers to the structure of an argument—if the conclusion follows logically from the premises. Soundness goes further and requires that the argument is not only valid but also that the premises are true.
Equality and Identity:
When we say "a = b" in logic, it usually implies identity. If "a" and "b" are interchangeable, it means they are the same in the relevant sense. Your example of chairs ("a" and "b") is correct in illustrating this concept. If everything predicated of "a" is the same as what is predicated of "b," then "a = b" holds in the logical context.
Substitution:
The concept of substitution is indeed fundamental in logic. If "a = b," you can substitute "a" for "b" or vice versa in logical expressions without changing the truth value of the expressions.
In summary, while logic does deal with individuals and identity, the equality symbol in logic typically denotes identity, not just equality in a quantitative or qualitative sense. Your explanation captures the nuances well, but it's important to recognize that in logic, "a = b" usually means that "a" and "b" are the same individual or object.

I understand your clarification. It seems you're emphasizing the distinction between identity and equality in a more general sense. In everyday language and certain philosophical discussions, people might use terms like "equal" to indicate a similarity or equivalence without implying absolute identity.

When you say "you and I are not the very same individual, we are equal," you're pointing out that while we may not be identical individuals, we can still be considered equal in certain respects—perhaps in terms of rights, dignity, or some other criterion.

In logic, the symbol "=" typically denotes identity, meaning the very same individual or object. However, in other contexts, including philosophical and everyday language, people might use "equal" more loosely to convey a sense of similarity or equivalence without implying strict identity.

Your clarification aligns with this distinction, and it's important to be aware of the context in which terms like "equal" and "identical" are used, as they can carry different meanings in different discussions.

Your grade school exercise touches upon an interesting concept, and I appreciate your engagement with it. Let's break down the reasoning:

Representation:
You represent yourself as 1, and me as 1. When we come together, you correctly state that we represent the combination as 1 + 1 = 2.
Equality:
You rightly point out that for this representation to make sense, the two individual "1"s must be equal. So, you say 1 = 1.
Logical Concern:
You raise a concern about the meaning of "=" in the context of 1 + 1 = 2. If "=" means that both "1"s are the same, then it seems contradictory because, in that case, there would be only one, not two.
Your concern is related to the distinction between the concepts of equality and identity. In the context of arithmetic, when we say 1 + 1 = 2, we are not implying that the individual "1"s are identical; rather, we are saying that they are equal in value. In mathematical terms, "=" typically denotes equality, not identity.

So, while 1 = 1 in the sense that the individual "1"s are considered equal, when we say 1 + 1 = 2, we are combining two equal values to get a sum of 2, without suggesting that the individual "1"s are the same in an identity sense. It's a fundamental aspect of arithmetic and mathematical notation that "=" often represents equality, not identity.[/chat] — ChatGPT
