if the very same thing is referred to on the right and the left, use of the '=' is valid. That is because a thing cannot be unequal to itself. But since there are many instance when the right and the left refer to something different, we cannot conclude that '=' signifies identity. — Metaphysician Undercover
n common, pervasive usage in mathematics, as I mentioned, a formula
T = S
is true (or satisfied) if and only if 'T' and 'S' refer to the same object.
— GrandMinnow
This is a false statement. It is very evident from the common use of mathematics, and even your example of "free variables", that the right and left side usually do not signify the very same thing. — Metaphysician Undercover
Replying to MU:

The reason you are not familiar with that fact is that you are not familiar with rigorous mathematics and especially as mathematics is treated in mathematical logic. — GrandMinnow
The concept of tree is not the same as the concept of tree, because there are accidental differences in each instance that it occurs, therefore it violates the law of identity and cannot be an object. — Metaphysician Undercover
Because the law of identity applies to objects only, and a concept is not an object, I don't think there is a valid way to say that a concept might be identified. Instead, we define concepts. If we proceed to state that a definition identifies the concept, then we are in violation of the law of identity. A definition exists as words, symbols, so now we'd be saying that the identity of the concept is in the words, but by the law, the identity must be in the thing itself. That's why a concept does not have an identity. However, if we assume an ideal, as the perfect, true definition of tree, an absolute which cannot change, then this ideal concept could exist as an object. Every time "tree" is used, it would be used in the exact same way, to refer to the very same conceptual object. But I don't think that this is realistic. — Metaphysician Undercover

So, you’re saying that ‘identity’ is the same as ‘esse’?
— Wayfarer
I can't answer this because I'm not familiar with the word esse. I don't think it's English and it doesn't enter my translations. I am familiar with 'essence' and with 'essential' and they both have a range of usage. — Metaphysician Undercover
In philosophy, essence is that which makes a thing be what it fundamentally is. It is often called the “nature” of a thing such that it possesses the necessary characteristics or properties in contrast with merely accidental or contingent ones. It is often considered a specific power, function, or internal relation (or set of relations) which again makes the thing be the kind of thing that it is. The notion of essence has acquired many slightly but importantly different shades of meaning throughout the history of philosophy, though most of them derive in some manner from its initial use by Aristotle.
The value of the operation + applied to the operand pair <2 2> is 4. Thus the equation 2+2=4 is true. — GrandMinnow
That's the way it works in mathematics. Your philosophy about things does not refute mathematics. Meanwhile, if you wish to continue to ignore how mathematics actually works and instead insist on your philosophy, then you would do better to present a systematic development of the subject with your alternative premises, definitions, and notations listed, and not continue to post disinformation about mathematics you know nothing about. — GrandMinnow
By this argument, no continuity of (the Aristotelian notion of) any substance can occur, for any physical object will have accidental differences between itself at any time t and t'. Yet (the Aristotelian notion of) substance - as I best understand it - is precisely that with is identical relative to itself over time; more precisely, that which survives accidental changes (implicitly, over time). In much the same way, the concept of tree remains identical relative to itself over time; i.e., it survives accidental changes, or differences, over time. — javra
When we say “tree” and a Spaniard says “arbol” are not the concepts denoted by each different term identical - this despite possible accidental differences in the two term’s connotations? As in: the concept of tree, T, is the same as the concept of arbol, A. Hence T = A. — javra
Given that the definitions of each will utilize different words, the English definition of “tree” and the Spanish definition of “arbol” might very well not be identical; but both definitions will define an identical concept. Again, one that survives accidental changes, including those of possible differences in connotations. — javra
It is often wise to be wary of high school level explanations and terminology that need to be made rigorous and even corrected by rigorous mathematical treatments (for a salient example, the definition of 'function'). — GrandMinnow
I think that you are equating, or conflating, ‘essence’ and ‘identity’. — Wayfarer
"Each thing itself, then, and its essence are one and the same in no merely accidental way, as is evident both from the preceding arguments and because to know each thing, at least, is just to know its essence, so that even by the exhibition of instances it becomes clear that both must be one." 1031b,18. "Clearly, then, each primary and self-subsistent thing is one and the same as its essence. The sophistical objections to this position, and the question whether Socrates and to be Socrates are the same thing, are obviously answered by the same solution; for there is no difference either in the standpoint from which the question would be asked, or in that from which one could answer it successfully." 1032a,5.
...
"What the essence is and in what sense it is independent has been stated universally in a way which is true of every case, and also why the formula of some things contains the parts of the thing defined, while that of others does not. And we have stated that in the formula of the substance the material parts will not be present (for they are not even parts of the substance in that sense, but of the concrete substance; but of this, there is in a sense a formula, and in a sense there is not; for there is no formula of it with its matter, for this is indefinite, but there is a formula of it with reference to its primary substance---e.g. in the case of man the formula of the soul---for the substance is the indwelling form, from which and the matter the so-called concrete substance is derived; e.g. concavity is a form of this sort, for from this and the nose arise 'snub nose' and 'snubness'); but in the concrete substance, the matter will also be present, e.g. a snub nose or Callias, the matter will also be present." 1037a 21-32. — Metaphysician Undercover
And this is supported by reference to Plato's Socratic discussion of 'snub nose' and form of 'Snubness' at 1037a?Aristotle's Metaphysics, 1032a -- Each thing itself, then, and its essence are one and the same in no merely accidental way — Metaphysician Undercover
In Aristotelian physics temporal continuity is provided for by matter. Matter is what persists, unchanged as the form of a thing changes, and substance contains matter. Today, this is represented by conservation laws, energy and mass. Accidentals are formal, as part of a thing's essence. The problem with representing "the concept" in the same way, as having temporal continuity, is that it seems to be immaterial. So it seems like we need a principle other than the physical "matter" to account for any temporal continuity of a concept. We might try 'information' to account for the identity of a concept, but that doesn't remain constant over time, so identity of the concept would be completely different from identity of an object, if we were to develop such a principle. — Metaphysician Undercover
Aristotle defines X's matter as "that out of which" X is made.[1] For example, letters are the matter of syllables.[2] — https://en.wikipedia.org/wiki/Hylomorphism#Matter_and_form

But from a brief perusal on the Internet, I see that that usage is found mainly in high school level algebra texts (and "college" level that is seen in the examples to be really review of high school level). — GrandMinnow

"Clearly, then, each primary and self-subsistent thing is one and the same as its essence." ~ Aristotle — Metaphysician Undercover
Unfortunately, Aristotle was a logician and not a foundational mathematician like Plato, and distinctions implicit in Plato's discussions directed at Pythagorean mathematicians were lost in the translation. — magritte
From such quotes I interpret Aristotelian matter to be fairly synonymous with composition. A material cause is a compositional cause, for instance, one whose effects are bottom-up and concurrent with the composition as cause. — javra
So Aristotelian matter need not be physical (as we moderns interpret it to be). For a somewhat easier example by comparison to a concept, a paradigm's Aristotelian matter is, or at least can be, the sum of ideas from which it is composed. This in the same way that a syllable's matter is the sum of letters from which it is composed. — javra
As someone who speaks two languages fluently, I wholeheartedly disagree with this. Yes, some concepts do not translate in a single word, if at all. But basic concepts (again, generalized ideas), such as that of "tree", are the same across multiple cultures regardless of the language via which they are addressed (given that the populace is exposed to concrete instantiations of trees in its environment). — javra
The complexities of language aside, if no such scribble could convey the same (essential) concept between two different people, how would communication of anything be possible? — javra
What is included in the category of 'primary and self-subsistent things'? Do tools and artefacts belong in that category? Do they have 'an identity' according to this criteria? — Wayfarer
I don't think that you can call the parts of a thing as the cause of its composition. — Metaphysician Undercover
Aristotle assumed that there was matter so that he could say that an object has an identity, and to insist that it continues to be the same object despite changes to it. This was an argument against philosophers like Heraclitus who would say that all is flux, becoming, disputing the idea that there even is any real objects. — Metaphysician Undercover
So does a hammer meet ‘the condition of identity?’ — Wayfarer
What I was suggesting is that its summation of parts, or constituents, *is* its composition/matter. This such that “matter” and “composition” can be used interchangeably. — javra
Reworded, the bronze statue is dent-able (rather than shatter-able or burnable) due to its composition as the cause of its dent-ability. Again, such that composition and matter are in the addressed Aristotelean context interchangeable. — javra
So, in my quirks of interpreting Aristotle, if we’re looking to affix identity strictly to that which is permanent, unchanging, then this cannot be matter but instead can only be form: specifically, that matter-less/composition-less form which specifies the identity of the unmoved mover as telos. — javra
So I am disagreeing with your use of "composition". I think it is misleading, implying that we can remove the particular arrangement of the parts as inessential to the composition. — Metaphysician Undercover
1. The act of putting together; assembly.
2. A mixture or compound; the result of composing. [from 16th c.]
3. The proportion of different parts to make a whole. [from 14th c.]
4. The general makeup of a thing or person. [from 14th c.] — https://en.wiktionary.org/wiki/composition
What is inevitable with this process of reduction of the matter, is the appearance of infinite regress. — Metaphysician Undercover
The bottom-up form, which is properly an immaterial form, as responsible for the cause of material objects, is the form of an individual, rather than a universal form. [...] The teleological form, associated with intention and final cause is the bottom-up cause. — Metaphysician Undercover

Further, in Aquinas there is described a complete separation between the forms as universals which are dependent on the human mind, and therefore not separate from matter, and the independent or separate immaterial Forms such as God and the angels — Metaphysician Undercover
if the proper knowledge of the senses is of accidents, through forms that are individualized, the proper knowledge of intellect is of essences, through forms that are universalized. Intellectual knowledge is analogous to sense knowledge inasmuch as it demands the reception of the form of the thing which is known. But it differs from sense knowledge so far forth as it consists in the apprehension of things, not in their individuality, but in their universality.
...“Abstraction, which is the proper task of active intellect, is essentially a liberating function in which the essence of the sensible object, potentially understandable as it lies beneath its accidents, is liberated from the elements that individualize it and is thus made actually understandable. The product of abstraction is a species of an intelligible order. Now possible intellect is supplied with an adequate stimulus to which it responds by producing a concept.”
One one hand, these definitions are in accord with Aristotle's definition of matter as ""that out of which" X is made — javra
The latter being more in-tune with what Aristotle meant. — javra
This part to me is a bit confusing. Are you saying that formal causation is a bottom-up causation? Or that a hylomorphic given's form is the result of material causation, with the latter being bottom-up? Or something other? — javra
I query this analysis. That would make Aquinas a conceptualist - 'Conceptualism is a doctrine in philosophy intermediate between nominalism and realism that says universals exist only within the mind and have no external or substantial reality.' Aquinas was not a conceptualist, but a scholastic realist, whom by definition accepts the reality of forms. — Wayfarer

Buddhism says that there is nothing that constitutes an 'ultimate identity' in this sense whatever. — Wayfarer
I also question the tendency to 'absolutize' the forms. I think they're real on a specific level, viz, that of the 'formal realm' which 'underlies' the phenomenal realm but they can't be pinned down or ultimately defined. — Wayfarer
I don't agree, I think "that which constitutes" is closer to what Aristotle meant than "composition". — Metaphysician Undercover
What I'm saying is that I believe that final causation, intention, will, is bottom-up. Formal cause, which we apprehend as acting top-down, is distinct from final cause. — Metaphysician Undercover
So, to me, there is a type of temporality involved with a telos. This to me stands in contrast to both bottom-up and top-down determinants, both or which strictly occur in the specified moment of time without any temporal extensions into the future. — javra
I don't think we can correctly say that anything occurs in a moment of time without any temporal extension. All occurrences require duration. Therefore I do not think we can exclude "bottom-up" and "top-down" from a temporal analysis. — Metaphysician Undercover
To address this via example, if a wooden table’s burnability holds as its material cause the wood out of which the table is constituted, what duration occurs between a) the material cause of wood and b) the table’s intrinsic potential to burn?
So far, to me (a) and (b) seem to be necessarily simultaneous, with no duration in-between, while standing in a bottom-up relation. — javra

The utterly, literally, selfless state of awareness (hence, a state of awareness devoid of all duality) which is Nirvana - more correctly in this context, "nirvana without residue" - seems to be interpretable, to me at least, as the ultimate identity of all sapient beings — javra
Concepts, or predicates, are always universals, which means that no individual can be defined, as an individual, by concepts. "Socrates," as the name of an individual, although bringing to mind many properties, is not a property; and no matter how many properties we specify, "snub-nosed," "ugly," "clever," "condemned," etc., they conceivably could apply to some other individual. From that we have a principle, still echoed by Kant, that "[primary] substance is that which is always subject, never predicate." On the other hand, a theory that eliminates the equivalent of Aristotelian "matter," like that of Leibniz, must require that individuals as such imply a unique, perhaps infinite, number of properties. Leibniz's principle of the "identity of indiscernibles" thus postulates that individuals which cannot be distinguished from each other, i.e. have all the same discernible properties, must be the same individual. — https://www.friesian.com/universl.htm
An individual number's identity (say, the number 2) would then likewise be the gestalt that results from all of its properties: this gets far more tricky due to the degree of abstraction, but maybe including those of duality, its placement within the appropriate context of other numbers (e.g., greater than 1 but lesser then 3), and so forth.
Edit: I'm aware that the Wikipedia article on bundle theory makes a skimpy mention of "bundle theory of substance". More musings on this issue can be found here https://plato.stanford.edu/entries/substance/#BundTheoTheiProb . All the same, if anyone is interested in debating the notion of identity as a gestalt form emerging from a bundle of properties as parts, I'm curious to see in which ways this would be critiqued. — javra
We take a group of two and look at it as a single thing, and say that this thing has the property of consisting of two. There's no fundamental problem in saying that the group is not a true object, it's arbitrary, and arguing therefore that the only true object is the property which is assigned. — Metaphysician Undercover
Given what we've been through in terms of prime matter being pure potential and all givens being identified by their forms, why would the abstract form of "2" be deemed arbitrary rather than a "true (abstract) object"? Seems to me that basic numbers are not arbitrary, despite their very abstract nature; else, for example, 2 + 2 could equal 5 in certain cases. — javra
