    Pretty good tour of Sellars on the given for those who might prefer videos to books:

    This is more bite-sized and casual: https://www.youtube.com/watch?v=3uUYeZu1DIQ


    Here's a different, linguistic point that seems relevant.
    We begin with the question of whether there is a realm beyond my "immediate experience." Does the Empire State Building continue to exist even when I am not looking at it? If either of these questions can be asked, then there must indeed be a realm beyond my experience. If I can ask whether there is a realm beyond my experience, then the answer must be yes. The reason is that there has to be a realm beyond my experience in order for the phrase 'a realm beyond my experience' to have any meaning. ... The assertion 'There is realm beyond my experience' is true if it is meaningful, and that is precisely what is wrong with it. There are rules implicit in the natural language as to what is semantically legitimate. Without a rule that a statement and its negation cannot simultaneously be true, for example, the natural language would be in such chaos that nothing could be done with it. An example of implicit semantics is the aphorism that "saying a thing is so doesn't make it so." This aphorism has been carried over into the semantics of the physical sciences: its import is that there is no such thing as a substantive assertion which is true merely because it is meaningful. If a statement is true merely because it is meaningful, then it is too true. It must be some kind of definitional trick which doesn't say anything. And this is our conclusion about the assertion that there is a realm beyond my experience. Since it would be true if it were meaningful, it cannot be a substantive assertion.
    ...
    The methodology of this essay requires special comment. Because we are considering ultimate questions, it is pointless to try to support our argument on some more basic, generally accepted account of logic, language, and cognition. After all, such accounts are being called into question here. The only possible approach for this essay is an internal critique of common sense and the natural language, one which judges them by reference to aspects of themselves.

    As an example of the application of our initial result to specific questions of belief, consider the question of whether the Empire State Building continues to exist when I am not looking at it. If this question is even meaningful, then there has to be a realm in which the nonexperienced Empire State Building does or does not exist. This realm is precisely the realm beyond my experience. The question of whether the Empire State Building continues to exist when I am not looking at it depends on the very assertion, about the existence of a realm beyond my experience, which we found to be nonsubstantive. Thus, the assertion that the Empire State Building continues to exist when I am not looking at it must also be considered as nonsubstantive or meaningless, as a special case of a definitional trick.

    Philosophers ! I mean the 'serious' kind who labor together, subject to the norms of rationality, carefully building and testing the self-consciousness of the species. It's just us becoming more and more aware of ourselves in our talking about our talking about our talking. As Hegel might put, we little bald monkeys come and go, downloading the highlights of the conversation so far, maybe make a good point, and die. This conversation becomes more and more aware of itself as it continually moves to see itself from the outside, forever forging and extending its metacognitive vocabularies, making an otherwise necessary inheritance optional, sending out exploratory 'tentacles' (theories it's willing to drop if they don't live up to expectations), ...

    For instance, I love this dude for making explicit the philosophical situation itself.

    It is central to Brandom’s kind of rationalism that for him the behavior of the cardinals in my yard does not count as assessable in terms of their reasons; they are sentient, rather than sapient, to use a typical Brandomian turn of phrase. For Brandom, sentient beings, such as the cardinals, react differentially to their environments. But they do not count as sapient because they are incapable of the kind of responsibility and authority for their acts that is characteristic of being obliged, prohibited, and permitted, (and being committed to a certain course of action or entitled to something), and which, on his view, is necessary if an agent’s inferences are to be appropriately appraisable. The cardinals’ behavior amounts to an implicit categorization of the features of their environment, but this behavior does not depend upon the birds performing inferences to or from the applicability of those categorizations. It is his distinctive analysis of the nature of inference and of the practice of drawing and evaluating inferences that forms the core of Brandom’s understanding of rationality. An agent is rational in Brandom’s preferred sense just in case she draws inferences in a way that is evaluable according to the inferential role of the concepts involved in those inferences, where the inferential role of a concept is specified in terms of the conditions under which an agent would be entitled to apply, or prohibited from applying, that concept, together with what else an agent would be entitled or committed to by the appropriate application of the concept. This articulation of the content of concepts in terms of the inferential role of those concepts, and the specification of those roles in terms of proprieties of inference, is combined with a distinctive brand of pragmatism. Instead of the content of a concept providing an independent guide or rule that governs which inferences are appropriate, it is the actual practices of inferring carried out in a community of agents who assess themselves and each other for the propriety of their inferences that explains the content of the concepts.

    We so others (from the outside) as creatures with eyes and ears and noses and brains. If we check in their skulls, we don't expect to find a soul, not with the naked eye. We trust that a man without eyes is blind and that a man without a living brain is not present at all but only a corpse.

    I suggest that this third-person POV lends an initial plausibility to what I'll call the enclosure theory.

    Within this theory, we think of atoms or waves banging against nerve cells, causing the brain to put on a magic show for (or as) the ghost in the machine. The ghost knows what it means to say, even if the words are hard to find, because meaning, like sensation, is ectoplasmic ghost stuff. The 'ghost' or 'soul' is 'behind' or hidden in the body in some strange way...just as meaningstuff is 'behind' or hidden in the words that carry it.

    It's not hard, though, to describe experience in its entirety as meaning-structured sensation. So somehow it becomes plausible that only the ghost is real ! Despite its birth in a third-person point of view. The source of justification of the view was atoms/waves that 'really' exist for all of us banging away at our individual nervous systems, so that a colorblind or nearsighted person will talk and act a little differently...see the 'same' things differently. But if the sense organs and the atoms and waves are all just entities in a dream, the whole theory of the dream loses its plausibility. And if I'm not a self among others trying to be trustworthy and trust the right people, the whole concern with truth and reality and certainty no longer makes sense.

    In particular, I'd emphasize this element in Saussure, especially given the original purpose to emphasizing the need for contrastive force. (If everything is X, then we might as well say nothing is, for nothing is picked out.)

    Value is the sign as it is determined by the other signs in a semiotic system. For linguist Ferdinand de Saussure, for example, the content of a sign in linguistics is ultimately determined and delimited not by its internal content, but by what surrounds it: the synonyms redouter ("to dread"), craindre ("to fear"), and avoir peur ("to be afraid") have their particular values because they exist in opposition to one another. If two of the terms disappeared, then the remaining sign would take on their roles, become vaguer, less articulate, and lose its "extra something" because it would have nothing to distinguish itself from.

    For de Saussure, this suggests that thought is a chaotic nebula until linguistic structure dissects it and holds its divisions in equilibriums.

    His conception of meaning was purely structural and relational rather than referential: primacy is given to relationships rather than to things (the meaning of signs was seen as lying in their systematic relation to each other rather than deriving from any inherent features of signifiers or any reference to material things).

His approach over the board was very pragmatic—in that respect, he is one of the heirs of ex-world champion Emanuel Lasker. He often sacrificed material in search of the initiative,[19] which is defined as the ability to make threats to which the opponent must respond. With such intuitive sacrifices, he created vast complications, and many masters found it impossible to solve all the problems he created over the board, though deeper post-game analysis found flaws in some of his conceptions.

    A nice companion to Popper's theory of us having only a swamp for a foundation :

    Sellars’s treatment of semantics essentially constitutes a denial of what can be called a semantic given—the idea that some of our terms or concepts, independently of their occurrence in formal and material inferences, derive their meaning directly from confrontation with a particular (kind of) object or experience. Sellars is anti-foundationalist in his theories of concepts, knowledge, and truth.

    Traditional epistemology assumed that knowledge is hierarchically structured. There must, it was believed, be some cognitive states in direct contact with reality that serve as a firm foundation on which the rest of our knowledge is built by various inferential methods. This foundationalist picture of knowledge imposes two requirements on knowledge: (1) There must be cognitive states that are basic in the sense that they possess some positive epistemic status independently of their epistemic relations to any other cognitive states. I call this the Epistemic Independence Requirement [EIR]. Positive epistemic statuses include being knowledge, being justified, or just having some presumption in its favor. (It was popular to claim that basic cognitions must possess an unassailable epistemic warrant — certainty, incorrigibility, or even infallibility — but this is not as common today.) Epistemic relations include deductive and inductive implication. (2) Every nonbasic cognitive state can possess positive epistemic status only because of the epistemic relations it bears, directly or indirectly, to basic cognitive states. Thus the basic states must provide the ultimate support for the rest of our knowledge, which I call the Epistemic Efficacy Requirement [EER]. Such basic, independent and efficacious, cognitive states would be the given. Many philosophers have believed that there has to be such a given, if there is to be any knowledge at all.

    Rejecting the myth of the given is not yet a positive epistemology. Sellars can abandon the myth of the given only if he gives us a positive theory of non-inferential knowledge to replace it. (There must be non-inferential knowledge, that is, knowledge that is not acquired by inference, even if its epistemic status depends on its inferential connections to other knowledge.)

    The paradigm cases of non-inferential knowledge are introspection, perception, and memory [IPM] beliefs (see MGEC). According to Sellars, such beliefs have epistemic status because, given the processes by which language and beliefs are acquired, they are likely to be true. IPM beliefs are reliable indicators, like the temperature readings on a thermometer. This is a reliablist or externalist condition on such knowledge. A chain of empirical justification can properly start with IPM beliefs because they are noninferential reliable indicators of the truth of their contents. Thus, their occurrence licenses an inference to the likely truth of their contents, and thence to other consequences by formal or material rules of inference.

    But Sellars is not, in the end, a reliablist. Thermometers may be highly reliable, but they have no knowledge. Sellars adds another condition: the subject must know that her IPM belief is reliable. This imposes a reflexivity requirement on knowledge.

    The point is not simply that knowers are capable of metajudgments. Sellars has a larger condition in mind: “The essential point is that in characterizing an episode or a state as that of knowing, we are not giving an empirical description of that episode or state; we are placing it in the logical space of reasons, of justifying and being able to justify what one says” (EPM: §36, in SPR: 169; in KMG: 248). This dictum needs to be combined with another well-known Sellarsian pronouncement: “Now the idea that epistemic facts can be analysed without remainder—even ‘in principle’—into non-epistemic facts, whether phenomenal or behavioural, public or private, with no matter how lavish a sprinkling of subjunctives and hypotheticals is, I believe, a radical mistake—a mistake of a piece with the so-called ‘naturalistic fallacy’ in ethics” (EPM: §5, in SPR: 131; in KMG: 209).
    ...
    In order to operate within “the logical space of reasons,” one must be at home with normative discourse, responsive to reasons as such, sensitive to standards of correctness and appropriateness. This requirement imposes a coherentist/holist condition that precludes the possibility of atomistically isolable cognitive states: any cognitive state, including bottom-level, non-inferential IPM beliefs, can be cognitive only as one element in a complex, reflexively structured system of such states responsive to epistemic norms and goals.
    ...
    Such a holism of cognitive states raises an obvious problem: how could one start acquiring cognitive states without falling into circularity or regress? The normativity of the cognitive is crucial to Sellars’s answer: we can acquire piecemeal by natural, causal pathways the individual habits and dispositions that, when present in sufficient numbers and appropriately interrelated, warrant the application of the normative language of cognition.
    ...
    Even so, Sellars rejects the traditional forms of both foundationalism and coherentism.

    One seems forced to choose between the picture of an elephant which rests on a tortoise (What supports the tortoise?) and the picture of a great Hegelian serpent of knowledge with its tail in its mouth (Where does it begin?). Neither will do. For empirical knowledge, like its sophisticated extension, science, is rational, not because it has a foundation but because it is a self-correcting enterprise which can put any claim in jeopardy, though not all at once (EPM §38, in SPR: 170; in KMG: 250).

    Just in case you haven't seen this.

    In this connection, in the Logic of Scientific Discovery Popper introduces the technical concept of a “basic statement” or “basic proposition”, which he defines as a statement which can serve as a premise in an empirical falsification and which takes the singular existential form “There is an X at Y”. Basic statements are important because they can formally contradict universal statements, and accordingly play the role of potential falsifiers. To take an example, the (putative) basic statement “In space-time region k there is an apparatus which is a perpetual motion machine” contradicts the law of the conservation of energy, and would, if true, falsify it (2002: 48). Accordingly, Popper holds that basic statements are objective and are governed by two requirements: (a) the formal, that they must be both singular and existential and (b) the material, that they must be intersubjectively testable.

    In essence, basic statements are for Popper logical constructs which embrace and include ‘observation statements’, but for methodological reasons he seeks to avoid that terminology, as it suggests that they are derived directly from, and known by, experience (2002: 12, footnote 2), which would conflate them with the “protocol” statements of logical positivism and reintroduce the empiricist idea that certain kinds of experiential reports are incorrigible. The “objectivity” requirement in Popper’s account of basic statements, by contrast, amounts to a rejection of the view that the truth of scientific statements can ever be reduced to individual or collective human experience. (2002: 25).

    Popper therefore argues that there are no statements in science which cannot be interrogated: basic statements, which are used to test the universal theories of science, must themselves be inter-subjectively testable and are therefore open to the possibility of refutation. He acknowledges that this seems to present a practical difficulty, in that it appears to suggest that testability must occur ad infinitum, which he acknowledges is an operational absurdity: sooner or later all testing must come to an end. Where testing ends, he argues, is in a convention-based decision to accept a basic statement or statements; it is at that point that convention and intersubjective human agreement play an indispensable role in science:

    Every test of a theory, whether resulting in its corroboration or falsification, must stop at some basic statement or other which we decide to accept. If we do not come to any decision, and do not accept some basic statement or other, then the test will have led nowhere. (2002: 86)

    However, Popper contends that while such a decision is usually causally related to perceptual experience, it is not and cannot be justified by such experience; basic statements are experientially underdetermined.

    Experiences can motivate a decision, and hence an acceptance or a rejection of a statement, but a basic statement cannot be justified by them—no more than by thumping the table. (2002: 87–88)

    Statements can be justified only by other statements, and therefore testing comes to an end, not in the establishment of a correlation between propositional content and observable reality, as empiricism would hold, but by means of the conventional, inter-subjective acceptance of the truth of certain basic statements by the research community.

    The acceptance of basic statements is compared by Popper to trial by jury: the verdict of the jury will be an agreement in accordance with the prevailing legal code and on the basis of the evidence presented, and is analogous to the acceptance of a basic statement by the research community:

    By its decision, the jury accepts, by agreement, a statement about a factual occurrence—a basic statement, as it were. (2002: 92)

    The jury’s verdict is conventional in arising out of a procedure governed by clear rules, and is an application of the legal system as a whole as it applies to the case in question. The verdict is accordingly represented as a true statement of fact, but, as miscarriages of justice demonstrate all too clearly,

    the statement need not be true merely because the jury has accepted it. This … is acknowledged in the rule allowing a verdict to be quashed or revised. (2002: 92)
    This is comparable, he argues, to the case of basic statements: their acceptance-as-true is also by agreement and, as such, it also constitutes an application of a theoretical system, and

    it is only this application which makes any further applications of the theoretical system possible. (2002: 93)

    However, the agreed acceptance of basic statements, like that of judicial verdicts, remain perennially susceptible to the requirement for further interrogation. Popper terms this “the relativity of basic statements” (2002: 86), which is reflective of the provisional nature of the entire corpus of scientific knowledge itself. Science does not, he maintains, rest upon any foundational bedrock. Rather, the theoretical systems of science are akin to buildings in swampy ground constructed with the support of piles:

    The piles are driven down from above into the swamp, but not down to any natural or “given” base; and if we stop driving the piles deeper, it is not because we have reached firm ground. We simply stop when we are satisfied that the piles are firm enough to carry the structure, at least for the time being. (2002: 94)
    https://plato.stanford.edu/entries/popper/#BasiStatFalsConv

    This connects to Sellars 'myth of the given' as well. To me it's not about denying sense-data but going around their uselessness in rational inquiry. To be clear, reports of sense experience play an important role. 'The computer flashed a measurement of 3.24313.' 'The litmus paper turned red.' The main idea is that we deal always with statements. Note also that we probably want to know who claims to have seen grandma's ghost or an alien mothership.

    I suppose one could argue that all such positions are effectively meaningless, e.g. Hempel's dilemma shows that it isn't even clear what it means for a thing to be physical/material, which will carry over to substance dualism, and then an analogous argument can made to show that it isn't even clear what it means for a thing to be mental.Michael

    Yeah, I think such positions are (informally) meaningless...or on the meaningless side of the spectrum, because they end could contributing to the invention of more determinate and practice claims.

    Words like 'mental' and 'physical' and 'real', when taken out of their more typical practical context, do seem fairly deficient in meaning. I think Saussure is basically right, that meaning lives in not 'behind' individual tokens but in contrastive applications. This is what attracts me about inferentialism. The meanings of concepts live in the networks of (appropriate) inferences that employ them. The proposition is primary, and 'I think' and 'I know' and 'seems to me' can be understood in terms of norms, of what I commit myself to, of the kind of actions that ought to be expected of me, having made this or that assertion. The unity of the self is just the 'ought to be' coherence of my beliefs and the unity of an avatar that's tracked by others for honesty and rationality and decency.

    Why should one worry about such a thing. If I look at what appears to be an apple and grab it, smell it, cut it, and taste it, and by all indication it is an apple. What error am I concerned about making in this scenario. My biological apparatus did a good job of picking out an object to nourish myself. What matters is if another human being has difficulties picking out such an object and what scientific/medical discoveries have be made to help that human being correct their biological apparatus to make better judgements about the external world around them. Additionally, if my apparatus is functioning as expected but I am fooled somehow that what appears to be an apple turns out not to be, and it becomes a consistent problem, well it may be time to do some creative thinking and come up with new detection method to help screen out the false positives.Richard B

    Lots of good points above. You stress practical relevance, and I'd extend that emphasis to semantics as well. What does it mean to take something as an apple ? Is the apple 'behind' all its appearences somehow? Or is 'apple' just the way we organize various conventional behaviors, including ways of talking?

    Let us consider as an example the simplest kind of entities dealt with in the everyday language: the spatio-temporally ordered system of observable things and events. Once we have accepted the thing language with its framework for things, we can raise and answer internal questions, e.g., "Is there a white piece of paper on my desk?" "Did King Arthur actually live?", "Are unicorns and centaurs real or merely imaginary?" and the like. These questions are to be answered by empirical investigations. ... The concept of reality occurring in these internal questions is an empirical scientific non-metaphysical concept. To recognize something as a real thing or event means to succeed in incorporating it into the system of things at a particular space-time position so that it fits together with the other things as real, according to the rules of the framework.

    From these questions we must distinguish the external question of the reality of the thing world itself. In contrast to the former questions, this question is raised neither by the man in the street nor by scientists, but only by philosophers. Realists give an affirmative answer, subjective idealists a negative one, and the controversy goes on for centuries without ever being solved. And it cannot be solved because it is framed in a wrong way. To be real in the scientific sense means to be an element of the system; hence this concept cannot be meaningfully applied to the system itself.
    ...

    In the case of this particular example, there is usually no deliberate choice because we all have accepted the thing language early in our lives as a matter of course. Nevertheless, we may regard it as a matter of decision in this sense: we are free to choose to continue using the thing language or not; in the latter case we could restrict ourselves to a language of sense data and other "phenomenal" entities, or construct an alternative to the customary thing language with another structure, or, finally, we could refrain from speaking. If someone decides to accept the thing language, there is no objection against saying that he has accepted the world of things. But this must not be interpreted as if it meant his acceptance of a belief in the reality of the thing world; there is no such belief or assertion or assumption, because it is not a theoretical question. To accept the thing world means nothing more than to accept a certain form of language, in other words, to accept rules for forming statements and for testing accepting or rejecting them. The acceptance of the thing language leads on the basis of observations made, also to the acceptance, belief, and assertion of certain statements. But the thesis of the reality of the thing world cannot be among these statements, because it cannot be formulated in the thing language or, it seems, in any other theoretical language.
    ...
    An alleged statement of the reality of the system of entities is a pseudo-statement without cognitive content. To be sure, we have to face at this point an important question; but it is a practical, not a theoretical question; it is the question of whether or not to accept the new linguistic forms. The acceptance cannot be judged as being either true or false because it is not an assertion. It can only be judged as being more or less expedient, fruitful, conducive to the aim for which the language is intended.
    ...
    Thus it is clear that the acceptance of a linguistic framework must not be regarded as implying a metaphysical doctrine concerning the reality of the entities in question.
    ...
    A brief historical remark may here be inserted.The non-cognitive character of the questions which we have called here external questions was recognized and emphasized already by the Vienna Circle under the leadership of Moritz Schlick, the group from which the movement of logical empiricism originated. Influenced by ideas of Ludwig Wittgenstein, the Circle rejected both the thesis of the reality of the external world and the thesis of its irreality as pseudo-statements...
    — Carnap
    Not saying that that is the final word, but I find it useful and convincing.

    If everything is X, then nothing is X. For X you can substitute 'false' or 'illusion' or even 'true' and 'real.'

    Saussure argued that signs only make sense as part of a formal, generalized and abstract system. His conception of meaning was purely structural and relational rather than referential: primacy is given to relationships rather than to things (the meaning of signs was seen as lying in their systematic relation to each other rather than deriving from any inherent features of signifiers or any reference to material things). Saussure did not define signs in terms of some 'essential' or intrinsic nature. For Saussure, signs refer primarily to each other. Within the language system, 'everything depends on relations' (Saussure 1983, 121; Saussure 1974, 122). No sign makes sense on its own but only in relation to other signs. Both signifier and signified are purely relational entities (Saussure 1983, 118; Saussure 1974, 120).
    ...
    Everything that has been said up to this point boils down to this: in language there are only differences. Even more important: a difference generally implies positive terms between which the difference is set up; but in language there are only differences without positive terms. Whether we take the signified or the signifier, language has neither ideas nor sounds that existed before the linguistic system, but only conceptual and phonic difference that have issued from the system. The idea or phonic substance that a sign contains is of less importance than the other signs that surround it. Proof of this is that the value of a term may be modified without either its meaning or its sound being affected, solely because a neighboring term has been modified (see p. 115).

    But the statement that everything in language is negative is true only if the signified and the signifier are considered separately; when we consider the sign in its totality, we have something that is positive in its own class. A linguistic system is a series of differences of sound combined with a series of differences of ideas; but the pairing of a certain number of acoustical signs with as many cuts made from the mass thought engenders a system of values; and this system serves as the effective link between the phonic and psychological elements within each sign. Although both the signified and the signifier are purely differential and negative when considered separately, their combination is a positive fact; it is even the sole type of facts that language has, for maintaining the parallelism between the two classes of differences is the distinctive function of the linguistic institution.
    ...
    Value is the sign as it is determined by the other signs in a semiotic system. For linguist Ferdinand de Saussure, for example, the content of a sign in linguistics is ultimately determined and delimited not by its internal content, but by what surrounds it: the synonyms redouter ("to dread"), craindre ("to fear"), and avoir peur ("to be afraid") have their particular values because they exist in opposition to one another. If two of the terms disappeared, then the remaining sign would take on their roles, become vaguer, less articulate, and lose its "extra something" because it would have nothing to distinguish itself from.

    For de Saussure, this suggests that thought is a chaotic nebula until linguistic structure dissects it and holds its divisions in equilibriums. This is akin to the philosophy of Sir William Hamilton, who indirectly influenced Saussure and believed that the mind could only grasp an idea through distinguishing it from something that it is not. He reasoned that the two objects would otherwise collapse together for the mind and become indistinguishable from one another.

    Within modern philosophy there are sometimes taken to be two fundamental conceptions of idealism:

    (1) something mental (the mind, spirit, reason, will) is the ultimate foundation of all reality, or even exhaustive of reality, and

    (2) although the existence of something independent of the mind is conceded, everything that we can know about this mind-independent “reality” is held to be so permeated by the creative, formative, or constructive activities of the mind (of some kind or other) that all claims to knowledge must be considered, in some sense, to be a form of self-knowledge.

    Idealism in sense (1) has been called “metaphysical” or “ontological idealism”, while idealism in sense (2) has been called “formal” or “epistemological idealism”. The modern paradigm of idealism in sense (1) might be considered to be George Berkeley’s “immaterialism”, according to which all that exists are ideas and the minds, less than divine or divine, that have them.

    The first kind of idealism, labelled (1), is going to use some 'godmind' stuff to play the role of 'matter' or (more generally) the substrate of the world-in-common. I agree with Carnap that calling the system of objects as a whole either 'mind' or 'matter' or 'peanut butter sandwiches' is pointless. Except that it tickles the religious imagination, I guess.

    The second kind of idealism, labelled (2), is lipstick on a tautology. It's not surprising that human knowledge is the product of human conversation, or that it sure is hard to imagine or cognize what objects are like apart from all human imagination or cognition. It's all based on something like a function metaphor. The 'official Cartesian story' is that all we get can ever hope to get is a private showing of , where is the hidden truth and is human cognition. Then it's a small step for the solipsist to worry that maybe is just a theory, just a comforting or useful hypothesis...forgetting that the functional metaphor itself is anything but necessary, and that it derives its initial plausibility from taking the bodies of others in the world to be real, so that sense organs and inherited concepts are understood to mediate some otherwise fleshless forever-hidden 'skeleton' of the familiar, shared world.

    In Ukraine, for example, there's a not insignificant number of the population who wanted to be under Russian rule, or who couldn't care less whose flag they were under.Isaac

    That indeed makes it messier and more questionable.

    So the question is - if these people don't want to risk their deaths for the gain being offered, then in what sense is forcing them to do so in their interests (the people)?Isaac

    To me it's only reasonable/decent to pressure people to fight whose lives are already in serious danger -- and who otherwise plan to remain safe only at the cost of those who take up the burden. Even then it might not be prudent to trust the reluctant in battle.

    The guy who makes me die for a cause I don't believe in is my enemy, no matter what flag he waves. Forbidding males leaving seems wrong. I doubt the leaders and the rich are exposing themselves much to danger.

    This connects to the menu we're stuck with. It's also relevant to main topic.

    Claiming to know something, therefore, is attributing a certain status to ourselves -- the status of being bound by what we know. Yet this status, like all others, is instituted by our normative attitudes. Knowing is thus not simply finding ourselves, but taking ourselves, to be bound by reality, and indeed taking reality to be a certain way. The empirical concepts we judge to be objective are formulated in response to "noninferential observation reports" (p. 616) -- to what we perceive -- but they are not simply read off the world. They are instituted by our attitudes and practices. This is Brandom's "pragmatism about semantics" and cognition (p. 753).

    How, though, can we be bound by the norms and normative statuses that we institute? This is made possible, Brandom contends, by "a social division of labor". It is "up to me" whether I claim the coin is made of copper; but if I do so, then what I commit myself to, "what is incompatible with it and what its consequences are, is administered by those I have granted that authority by recognizing them as metallurgical experts" (p. 704). Norms are thus instituted as binding norms in social processes -- processes involving claims by some and assessment of those claims by others, as well as reciprocal recognition between the individuals concerned. This is true whether those norms govern cognition or action.

    Yet this is not the end of Brandom's story, for what is also needed, if we are to establish genuinely binding norms, is a way to vindicate those we now endorse, to regard them as truly objective. We do this, Brandom claims, by retrospectively "reconstructing" the social experience that led to our current endorsement of a norm. Specifically, we have to reconstruct the past process of instituting new norms -- through the experience of error and its "repair" -- as one in which the norm we now endorse has become progressively more explicit and thereby been discovered (pp. 370-1). This in turn requires us to regard that norm as having implicitly governed our cognition "all along" and in that sense to be "objective" (p. 680). Note that such "recollective" reconstruction of experience does not give us direct access to the "truth". It is, rather, how we come to understand ourselves now to be knowing something objective: for we regard our currently accepted norm as objective by taking it to have been found through the process of making new norms. It is through such recollection, therefore, that we justify to ourselves our conceptual realism; and the thesis that the latter requires the former is what Brandom calls "conceptual idealism" (p. 369). Like objective idealism, conceptual idealism does not claim that the world exists only insofar as we do something. It claims only that we must do something -- recollectively reconstruct our experience as progressive -- if we are to take ourselves to know the world. Conceptual idealism is thus not what Hegel would call a "subjective" idealism, but rather a pragmatist thesis about cognition.

    Lots of this is implicit in our showing up to play philosophy in the first place. If I think that I am making a case for a thesis that should therefore be respect, then I'm forehead-deep in a world with others, responsible for what I assert and believe according to community norms. And philosophy as we take it for granted supposed universal or global or even galactic norms.

    Idealism seems me to be a tautology misunderstood as a profundity.

    We can't have knowledge-independent knowledge of something.

    how is this stream of philosophy NOT an academic exercise? Intellectual gamesmanship?GLEN willows

    Some of it arguably is, but note that 20th century philosophy is largely a critique of that which came before, in terms sometimes of its uselessness or vanity.

    I like thinking of philosophy as something like the big picture thinking of an educated person. How does it all hang together?

    And we'll both go to a "better place" not knowing if idealism, solipsism or realism are the most accurate ways of knowing the world (if there is one).GLEN willows

    But it seems that you say 'we' will go to a better place, without knowing whether there's a we ? And you invoke accuracy, as if there is a 'real' world that our theories can describe or represent more accurately.

    Cool link.

    I recently read books by Peter Gay and Ernst Cassirer on the philosophy of the Enlightenment, and it became clear to me that that was the breakthrough (or the revival of the Greek breakthrough, if you like.) This is maybe why pragmatism appealed to me in its tendency to diminish the aura of metaphysics. I also relate to Popper's annoyance with (merely) verbal problems. And Wittgenstein's demolition of Cantor's paradise.

    The mind could still be deterministic though, with its own set of laws, oui?Agent Smith

    Hobbes and Spinoza (as I understand it) didn't run away from those implications. For Hobbes, the mind was subject to the same laws (was ultimately material, or determined by its material substrate.) (I'm fuzzy on some of this and open to correction. )

    I guess the logic is that by living in a country, you enjoy all the benefits provided by it, and that if the country's existence is threatened, you owe it to the country as your duty to fight and possibly die in order to preserve it._db

    Conscription for a defensive war strikes me as far more...defensible that that for an offensive war.

    It does seem a little wrong to stay behind in a safety that is only made possible by the risk of others. This seems like a version of freeloading. The devil is in the details though. Do we send old men ? Teenaged boys ? The differently-abled? It's going to be messy.

    If possible, perhaps those who didn't want to fight could be allowed to leave the country entirely, as a kind of compromise. "You don't have to kill/die for us, but we don't have to kill/die for you either."
