    In the theory of computation (for me math at its most objective), the symbol is often left formally undefined. By 'symbol' I mean a single character like 'a' or '1.' (It is also allowable to understand '1de' as a single symbol. We'd be creating a new glyph from familiar glyphs. )Once a symbol is defined, theoretical computer science can go very far with a theory of strings and sets of these strings called languages. It can comment on whether a language can be recognized with a finite amount of memory (number of states.) It can comment on whether a language can be recognized with an infinite amount of memory (which is essentially an infinite number of states). Since languages can be understood in terms of answers to objective mathematical questions (about whether still other machines will accept this or that language, for instance), I find this kind of science highly philosophically relevant. But the edifice is built on the intuitive recognition of this undefined thing, the symbol.

    If I use a pencil or a typewriter to make the mark 'a' several times, then these individual marks are not strictly identical. Moreover they are in different places. But we can recognize the marks as representing or intending the same symbol. A rose is a rose is a rose, and an 'a' is an 'a' is an 'a.' If I can't recognize that two different but similar marks intend the same abstract, distinct but otherwise undetermined entity, then I cannot understand Sipser's Theory of Computation, for instance.

    So the first step into objectivity that can be made explicit (creating strings and languages formally from symbols) is founded upon a step that cannot or has not been made explicit (understanding what a symbol is or how they work). To be clear, I think this inexplicit step is objective. I trust theoretical computer science more than I trust most disciplines. I just find this dark, first leap fascinating, and I also think there's an analogy in ordinary language (the dark, first step) and science/philosophy (pursuing objectivity from an inexplicit basis.) I mostly hope to start a conversation, and it would be great to meet others, also, with a passion for the theory of computation. Perhaps because it is so 'concrete' and (in my view) for that reason especially objective.

    The recognition of a pattern of light and dark as an instance of a particular symbol is made explicit in the coding of optical character recognition software. I haven't looked at character recognition programs but I can imagine the sort of rules they'd have. You probably can too, as it sounds like you are doing comp sci. We could define a character 'a' as any pattern of light and dark that satisfies the 'a' test of a certain character recognition program.

    Character recognition software is not foolproof but then neither is human character recognition

    Right. In fact our character recognition is imperfect, but it's not practically a problem. I suppose I would just comment that justifying or making explicit character recognition would happen outside of theoretical computer science (which as I understand it is a kind of pure math.) Actual computers would rely on physics, induction, etc. Roughly, the idea of the deterministic computer seems to be founded on the 'given' understanding of the symbol as symbol. Turing, for instance, assumes that his machine can recognize the symbol in the scanned square. This symbol is something like a Platonic form, though we use marks as an aid to memory. I think Turing wanted his machine to be as concrete and mark-fed as possible, but categorizing marks gives the symbol. Better said, the informal program ability that maps an infinite set of marks to a finite set of intended symbols is assumed. Moreover, the mark printed by the machine is really a symbol if it is to be of value.

    I think you're possible over-valuing objectivity. The point I would make is that mathematics is not necessarily objective, because it's purely inferential or logical - if this then that. And this is why mathematics can be used to determine what is objective. That is what is done through quantitative analysis, after all: you create an hypothesis, and then look at the data, to see how it fits - which is, arriving at an objective value. All of that relies on mathematical analysis. So mathematical reasoning is in some sense prior to objectivity.

    I suppose what I especially mean by 'objective' here is 'not a matter of opinion.' If physics is objective, this depends on the uniformity of nature, an often implicit axiom of the gut. Math would be objective, I'd argue, as long as the truth of the implications you mention is established. It would rest (ideally) on logic alone, and not on experience and the uniformity of nature. In the theory of computation, not much is used beyond mathematical induction and proof by contradiction. The implications it establishes seem timeless. It seems logically impossible that they should become false.

    That is true, but I still think ‘objectivity’ has epistemological or metaphysical implications which are unwarranted in the context. I’m not just picking nits here, either. The roots of mathematical philosophy are as ancient as philosophy itself - in the Greek tradition, the two are intertwined. But ‘objectivity’ as a criterion of truth is, I contend, something that is of very recent vintage, and carries an implication which I think is quite foreign to philosophy of mathematics in the traditional understanding.

    Is the language that is 'printable' (as I like to think of it) by a right linear grammar a 'regular' language (recognizable by a deterministic finite acceptor)? Yes. How do we know? Because we have an algorithm for converting such a grammar into an associated DFA. I can be certain of this. I may waver forever about the metaphysical interpretation of the symbols, but a functional understanding of the symbols is enough to establish the theorem. A person might say that math deals with the abstract 'how' of symbols. I don't have to know what they metaphysically are (if this is even meaningful an objective question) to obtain objective knowledge about what is possible with them in particular formal 'games' (models of computation, for instance.)

    If you are only saying that 'objectivity isn't everything,' then sure, of course not. But denying the objectivity of math strikes me as an attempt to hijack the usual meaning of a word 'objective.' (I looked it up just to make sure I wasn't imagining things --to make sure that I was being objective.)

    The beauty of a symbolic approach to math is its metaphysical neutrality. Can you not relate to the joy of occasionally getting beyond the field of opinion into a field of amusing/useful objective truth? This is made possible by a move from the 'what' to the 'how.' The essential 'what' of the the symbol (apart from the givenness of it), the rules that connect it to other symbols in various ways, is arguably this same 'how.' I can grant that it is not a science of marks. It is roughly a science of symbol crunching, whose objects are publicly available albeit non-physical, at least in part. (The science would be impossible without physical marks for the aid of memory and communication.)

    Mathematics is not objective. They are meaningless symbols upon which humans apply meaning. Without human interpretation they are no more meaningful than this may be &-+654()8.

    1+1=2 is a human symbolic creation.

    1 apple + 1 apple = 2 apples is a human observation if two humans agree on what is an apple. Hence the manner in which math is first taught in school.

    This fundamental first step, to overlook the fact that two distinct instances of "a" are not identical in an absolute way and are therefore not actually "the same", for the sake of calling them "the same", is the basic incoherency of logic. Some will dismiss it as a difference which does not make a difference, but if we are discussing the law of identity, then it is necessary that any difference makes a difference. Otherwise we undermine the meaning of "the same", and allow the contradictory notion that two distinct things are one and the same thing.

    A similar incoherency is found in the first step of mathematics, relating to the nature of "unity". The numeral "1" signifies a basic unity. The numeral "2" signifies two distinct unities, but also one unity as "two", at the same time. In performing mathematical operations we must overlook the fundament fact that "2" signifies two distinct unities, (just like we must overlook the fact that two distinct instances of "a" are not the same), and treat it as if it represents one unity.

    These incoherencies are fundamental to the logical process. Nevertheless we must overlook them, ignore them, to proceed into the logical realm. However, they are significant, and these flaws indicate that mathematics and logic are less than ideal.

    I see what you mean, but I also think logic is impossible without this first step. In other words, the logic you think is violated by the many-to-one map from marks to symbols is itself founded on this map, at least to the degree that it can be formalized. All abstractions seem to include this many-to-one map/function. I see a particular dog and recognize it as a dog by negating its particularity. I place it in a category. It seems to me that knowledge is impossible without this function from particulars to categories.

    A similar incoherency is found in the first step of mathematics, relating to the nature of "unity". The numeral "1" signifies a basic unity. The numeral "2" signifies two distinct unities, but also one unity as "two", at the same time.

    Again, I see what you mean. But I think we'd have to get into specific philosophical visions of mathematics. In a unary representation (often used in Turing machine computations), the number that has representation '2' in base 10 has the representation '11' (or '111' if zero is encoded as '1'). I agree that conceptually the number 2 is a unity of basic unities. When numbers are constructed in set theory, they are sometimes sets that contain all preceding numbers, where 0 is the empty set. Or 0, {0}, {{0}}, ... where the 'depth' of the empty set represents the number. In these representations, the nested 'unification' is apparent.

    These incoherencies are fundamental to the logical process. Nevertheless we must overlook them, ignore them, to proceed into the logical realm. However, they are significant, and these flaws indicate that mathematics and logic are less than ideal.Metaphysician Undercover

    I think math and logic are pretty ideal. For them not be to ideal, in my view, would mean that we could imagine something better. If we could imagine something better, then that would already be within math and logic, since anything better would conform to mathematical and logical requirements.

    Economically I've specialized in science, but I've read many philosophers. I try to avoid name-dropping and an addiction to any particular jargon and instead approach issues in ordinary language. Comprehension/assimilation and the value of the assimilated philosophy itself is manifest or not in what I do with it. You may occasionally recognize a paraphrase of a well-known idea.

    Fair enough. To try and re-state it - my point is that the criterion of objectivity is not necessarily applicable to mathematics (or logic for that matter), as the ‘objects’ of mathematics are only ‘objects’ in a metaphorical sense. They comprise what used to be called the domain of a priori truths. Objectivity introduces another element, which is derived ultimately from empiricism. But I do understand your objection, and acknowledge that I might be drawing a bit of a long bow.

    The meaninglessness of the symbols is one of the reasons that it is objective. There are truths about the game of chess that follow from the rules of chess. For instance, if I have only a king left on the board, then there is no way that I can checkmate my opponent. Proof: I would have to move into check to put the enemy king in check and mate, but I'm not allowed to move into check. If the rules are unambiguous, we can obtain objective knowledge about the game using logic. Or is it just my opinion that a lone king can't achieve checkmate?

    Whatever is outputted by a computer (a tool created by humans) must still be interpreted by humans with different opinions. Hence the phrase garbage in garbage out.

    Objectivity cannot exist in a subjective human experience.
    Rich

    It seems to me that you have to deny objectivity altogether to bring this home. You (pretend to) doubt 1+1 =2 and yet present your doubt itself as a binding, objective truth?

    The meaning of '1+ 1 = 2' is philosophically ambiguous. If, however, we specify a particular convention or 'game' of dealing with symbols as symbols, then all of this mystery vanishes --within that context.

    I'm inclined to think that some philosophy types relish a corona of ambiguity/mystery for its own sake and don't like even limited, clarifying, purpose-specific formalizations. For me, on the other hand, it's beautiful that we can invent 'spaces' in which strong objectivity is possible. In such spaces, a discovered truth stays discovered (and true) and can be more or less exactly communicated. Socially it's a utopia to that extent. The 'tax' on citizenship in this realm is an intellectual hygiene.

    If 'objective' is interpreted as meaning 'in some sense reliant on human minds' then my belief that 1+1=2 is not an objective belief, because it is based on my having a current memory of having reviewed a proof of the equation, and that memory is dependent on my mind. It could be an implanted memory.

    A notion of Strong Objectivity dissolves when one turns the microscope onto it. We can fall back on a notion of Pragmatic Objectivity, which is something like 'most people that have studied the topic would agree'.

    Sure, I won't argue with that. For me there is the 'false' doubt of [metaphysics] and then what I'd call genuine doubt. The notion of (infinitely) strong objectivity is arguably bankrupt if not even the most concrete, formal kind of math makes the cut. Because where is an example of such perfect objectivity? To me it 'smells' like something that comes from theology and Euclid in the first place. It's like the white smoke of an evaporated deity.

    As you say, we can 'fall back.' But I'd contend that this pragmatic objectivity is what is usually meant in the first place. So perhaps we don't 'fall' anywhere. Instead it's perhaps a vice of some philosophers to misread ordinary language. (Not aimed at you or anyone in particular, but rather especially at my past self before exposure to OLP and other civilizing influences.)

    Speaking of OLP, I like to call our inexplicit linguistic knowhow 'ordlang.' Just as ordlang makes philosophy possible, so an in-explicit grasp of the undefined symbol (along with ordlang, of course) seems to make a science of formal systems possible. This is an analogy I mentioned but didn't stress.
    I mention this to emphasize that my claim that formal systems are objective presupposed ordlang, but then so does any pursuit of explicit knowledge, it seems to me.

    Thanks for the polite response. I think you might be reading too much into the symbolic similarity between 'object' and 'objectivity.' If you look up 'objectivity,' you'll probably found what I found --no mention of objects but rather an emphasis on lack of bias. Here, also, is the top of the Wiki page on objectivity in the philosophical context:

    Objectivity is a central philosophical concept, related to reality and truth, which has been variously defined by sources. Generally, objectivity means the state or quality of being true even outside a subject's individual biases, interpretations, feelings, and imaginings. — Wiki

    But I can even answer your insincere question. _-++&__? is a finite sequence of symbols from a familiar alphabet containing one ?, one &, two +, etc. Anyone who can read the symbols as ordered from left to right (or right to left) will presumably agree, though some antisocial types might pretend not to (just as others will pretend to need a proof that they exist in another context, lost in vanity.) I count 8 symbols, so the length of that string is 8. These are objective truths in any reasonable sense of the word.

    I have only capitalized 'objective' recently as a joke, just to make that clear. For me philosophy is largely about demystification. The demystification of naive views or understandings of objectivity (the deflation of Objectivity) is (for me) old news. I understand myself to be working from a second demystification of philosophical language itself.

    For instance, we can say that math is 'just' another language game. We can say that humans are 'just' another animal. But what is this 'just'? It's an intentional ignorance of difference, useful in some contexts and questionable in others. I'm pro-choice, but calling an 8-month fetus 'just tissue' rings false for me. Similarly, putting math on the level of politics strikes me as a bit ridiculous. Yes, we almost universally want murder outlawed. You have picked, however, the least controversial issue possible, with the exception perhaps of laws that protect children. We need only look at real politics (actual controversy) to see the great gap. Or we can look at the endless metaphysical wrangling over the meaning of words. We can look at this very conversation. Educated people can and do disagree on a regular basis about politics and philosophy. But those who are educated enough to read math hardly ever disagree. A student or an expert may be temporarily confused, but generally math is an especially normal discourse. Philosophy, on the other hand, is the supremely abnormal discourse, with a permanent identity crisis --its glory and folly.

    I'm not suggesting that there is an absolute gulf between the science of formal systems and other language games, but then I think the concern with absolute gulfs is artificial in the first place. As I see it, it's the philosophers I'm criticizing who need absolute difference, absolute certainty, etc. I see no point in understanding the unqualified word 'objectivity' to have an 'impossible' meaning.

    If you are saying that humans are biased, then of course. Objectivity is something we pursue. In the case of formal systems there is very little room for bias. Interpreting formal systems from the outside of the system opens up the interstellar spaces for bias.

    We don't have to see an impossibly perfect instantiation of the concept to apply the concept. I doubt that anyone honestly believes that some disciplines aren't more objective than others. If formal systems give up meaning entirely for almost perfect objectivity, then physical science gives up certain aspects of experience to obtain its own above average objectivity. It's a trade-off.

Indeed I used to be a big believer in objectivity, seeing it as a crucial cleaver that cut through, dividing two fundamentally different types of thinking. But I gradually lost that certainty, and now all I see is differing degrees of confidence in beliefs, some of which are hard-wired into us by evolution.

    I think they only hope that the operation succeeds. Even if there is a right way to transplant a heart, doing it that way does not guarantee success, which is all the patient cares about.andrewk

    That is of course their primary hope. But I think they associate the likelihood of success with the trustworthiness or lack thereof of the discipline. Why not drink some magic potion suggested by a random stranger and hope for success? I agree that objectivity is 'cashed' pragmatically. Esthetic reasons aside for the moment, we don't want objectivity for its own sake. We want tools we can trust, tools that won't break in our hand. But this takes us right back to objectivity.

    Joe the Metaphysical Plumber tells me a purple spirit in haunting my pipes that he can exorcise for a small fee. Do I trust him? Probably not. Maybe he believes what he says, but maybe that's just his opinion (an idea false/useless for me despite its perceived use/truth for him). And that's probably because I'm familiar with other outlandish claims that didn't cash out. A child will believe perhaps in a giant bunny that brings candy once a year, that a fat man in red brings toys.

    At some point I start to reflect on this critical process itself (a pattern in my trusting or not). I come up with a word for the most trustworthy kind of claims. I notice that staying close to uncontroversial facts as a foundation seems to work. These might be facts about stones of different sizes dropped from a height or games of chess. In both cases an inexplicit knowhow grounds the non-controversiality of these facts. (I can't say what exactly it is to understand how a bishop moves, or what a person is, but it's not usually a problem.) Someone claims to find underground water by walking around with little sticks. OK. Let's see if they find water better than someone wandering around guessing. If they fail, it's logically possible that our observation somehow fizzled their power. But who cares? We need their 'magic' to work as needed, and not only when we aren't asking it to.

    I may even abandon an interest in explanation and focus on prediction and control, deciding that explanation often muddies the water. I can trust a black box if it gets the job done. That's how most people use their smartphones, I think. Prediction and control gets us near the pragmatic essence. What's left is morale, let's say. But even that is control of mood. Morale is tricky, though, because my mood is not a public entity. My behavior, sure, but whether I am 'happy' or 'enlightened' or 'saved' in some special 'metaphysical/religious' sense seems controversial. I may believe it, and others may shrug or spit. I can insist that it's an objective truth, that I am free of bias. But bias is almost by definition invisible to the biased person. We're back to the plumber believing in the purple spirit. I'm not denying the purple spirit. I'm saying it's going to be invisible for my criterion unless it leads to predictions and control. To be sure, these 'morale' entities obviously affect behavior, and I can imagine a black box that maps pubic words to predicted behavior. But the 'morale entities' themselves seem destined for invisibility in this sense, which is the way that many of their users like them, I think, for reasons that aren't necessarily cynical.

    I know this is a long response, but I tried to connect objectivity to a pragmatic epistemology. In short, objectivity is a concept that helps us decide which tools to trust.

    Instead we can just say that as humans we have evolved to instinctively trust what has worked in the past, so we trust surgeons, techniques and theories about how hearts function, that have worked in the past.andrewk

    Has the concept of objectivity served us well in the past? I'm not saying that this is an easy question. I'd suggest that it has served us well, but then I think most words that remain in the language are probably pulling their weight --even those filthy 'morale entities.'

    see what you mean, but I also think logic is impossible without this first step. In other words, the logic you think is violated by the many-to-one map from marks to symbols is itself founded on this map, at least to the degree that it can be formalized.mrcoffee

    Yes I agree that logic is impossible without this fundamental first step. But if contradiction is inherent within the first step, don't you see this as a problem? The first law is the law of identity. The second law is the law of non-contradiction. The very first step, to identify, has contradiction inherent within. So we identify first, then the law of contradiction says we cannot contradict. Aren't we obliged to either forfeit the law of non-contradiction, or go back to our mode of identification and rectify this problem of contradiction inherent within identification?

    When numbers are constructed in set theory, they are sometimes sets that contain all preceding numbers, where 0 is the empty set. Or 0, {0}, {{0}}, ... where the 'depth' of the empty set represents the number. In these representations, the nested 'unification' is apparent.mrcoffee

    I'm no mathematician, but I've noticed that set theory has contradiction inherent within it as well. I do not believe that the resolution to the problem of contradiction being inherent within the first step, is to introduce other contradictions to cover it up.

    I think math and logic are pretty ideal. For them not be to ideal, in my view, would mean that we could imagine something better. If we could imagine something better, then that would already be within math and logic, since anything better would conform to mathematical and logical requirements.mrcoffee

    To demonstrate imperfections within something is to demonstrate that it is less than ideal. It is not necessary to show the ideal, in order to demonstrate that what we have is not ideal. It may be the case that there is no such thing as the ideal, and then thinking what you have to be ideal is mistaken, while it is impossible to put forward an alternative as the ideal. To demonstrate problems within a system does not require that one put forward resolutions to the problems.
