I show that the central notion of Constructive Empiricism, empirical adequacy, can be expressed syntactically and specifically in the Received View of the logical empiricists. The formalization shows that the Received View is superior to Constructive Empiricism in the treatment of theories involving constants or functions from observable to unobservable objects. It also suggests a formalization of ‘full empirical informativeness’ in Constructive Empiricism.

Approximation involves representing things in ways that might be close to the truth but are nevertheless false. Given the widespread reliance on approximations in science and everyday life, here we ask whether it is conceptually possible for false approximations to qualify as knowledge. According to the factivity account, it is impossible to know false approximations, because knowledge requires truth. According to the representational adequacy account, it is possible to know false approximations, if they are close enough to the truth (...) for present purposes. In this paper, we adopt an experimental methodology to begin testing these two theories. When an agent provides a false and practically inadequate answer, both theories predict that people will deny knowledge. But the theories disagree about an agent who provides a false but practically adequate answer: the factivity hypothesis again predicts knowledge denial, whereas the representational adequacy hypothesis predicts knowledge attribution. Across two experiments, our principal finding was that people tended to attribute knowledge for false but practically adequate answers, which supports the representational adequacy account. We propose an interpretation of existing findings that preserves a conceptual link between knowledge and truth. According to this proposal, truth is not necessary for knowledge, but it is a feature of prototypical knowledge. (shrink)

Based on da Costa's and French's notions of partial structures and pragmatic truth, this paper examines two possible characterizations of the concept of empirical adequacy, one depending on the notion of partial isomorphism, the other on the hierarchy of partial models of phenomena, and both compatible with an empiricist view. These formulations can then be employed to illuminate certain aspects of scientific practice.An empirical theory must single out a specific part of the world, establish reference to that part, and (...) say—by way of contingent, substantial claim about the world—that its models fit that. Now, how exactly can this be done? Bas C. van Fraassen. (shrink)

Structural realism has been proposed as an epistemological position interpolating between realism and sceptical anti-realism about scientific theories. The structural realist who accepts a scientific theory thinks that is empirically correct, and furthermore is a realist about the ‘structural content’ of . But what exactly is ‘structural content’? One proposal is that the ‘structural content’ of a scientific theory may be associated with its Ramsey sentence (). However, Demopoulos and Friedman have argued, using ideas drawn from Newman's earlier criticism of (...) Russell's structuralism, that this move fails to achieve an interesting intermediate position between realism and anti-realism. Rather, () adds little content beyond the instrumentalistically acceptable claim that the theory is empirically adequate. Here, I formulate carefully the crucial claim of Demopoulos and Friedman, and show that the Ramsey sentence () is true just in case possesses a full model which is empirically correct and satisfies a certain cardinality condition on its theoretical domain. This suggests that structural realism is not a position significantly different from the anti-realism it attempts to distinguish itself from.

Situationists contend that virtue ethics is empirically inadequate. However, it is my contention that there is much confusion over what “empirical adequacy” or “empirical inadequacy” actually means in this context. My aim in this paper is to clarify the meanings of empirical adequacy in order to see to what extent virtue ethics might fail to meet this standard. I argue that the situationists frequently misconstrue the empirical commitments of virtue ethics. More importantly, depending on what we mean by (...) empirical adequacy, either virtue ethics has no need to be empirically adequate or where it does have such a need, the psychological evidence fails to show that it is empirically inadequate. An additional contribution the paper intends to make is to provide a more detailed discussion of the explanatory nature of virtue ethics. (shrink)

In order to judge whether a theory is empirically adequate one must have epistemic access to reliable records of past measurement results that can be compared against the predictions of the theory. Some formulations of quantum mechanics fail to satisfy this condition. The standard theory without the collapse postulate is an example. Bell's reading of Everett's relative-state formulation is another. Furthermore, there are formulations of quantum mechanics that only satisfy this condition for a special class of observers, formulations whose empirical (...) adequacy could only be judged by an observer who records her measurement results in a special way. Bohm's theory is an example. It is possible to formulate hidden-variable theories that do not suffer from such a restriction, but these encounter other problems. (shrink)

What are the requirements on an adequate genuine modal realist analysis of modal discourse? One is material adequacy: the modal realist must provide for each candidate analysandum an analysans in the language of counterpart theory which by his lights has the same truth value as the candidate analysandum. Must the material biconditional joining these be necessarily true? This is the requirement of strict adequacy. It is not satisfied if Lewis’s 1968 scheme provides the analysis. John Divers puts forward (...) a modification, which identifies cases of ‘advanced modalizing’ in which the modal operator is semantically redundant. Even with this modification modal realist analyses of statements of modal discourse will be strictly inadequate. Strict adequacy can be achieved by extending the redundancy interpretation to all de dicto modal statements. The price is the denial of de dicto contingency. But perhaps material adequacy is enough. If the modal realist has a systematic means of replacing every sentence of quantified modal logic which he considers true by a sentence of counterpart theory that he considers true, perhaps he need do no more. Still, traditionally philosophical analysis aims at strict adequacy so it is as well to know that this is a test the modal realist analysis fails unless he abandons de dicto contingency. (shrink)

Elizabeth Anderson and Debra Satz continue in the tradition of Plato with their work on the role of education in a just society. Both argue that a just society depends on education enabling citizens to realize democratic or civic equality and that this equality depends on sufficiency in the distribution of educational goods. I agree that education is important to preparing democratic citizens, but I disagree about the plausibility of sufficiency here, especially in the educational context. My argument is two‐fold: (...) I first reconsider a generic positional goods objection to educational inequality, I then argue that plausible sufficientarian replies to this objection fail insofar as they are premised on an impoverished conception of class and power that treats all statuses more like socio‐cultural traits when they should instead be referencing the material conditions someone has inside a social structure. One cannot bring an individual X into the halls of power and simultaneously have X represent or compensate those who are presently disadvantaged in the way that X had formerly been disadvantaged. In short, we should worry about the realistic possibility of securing and sustaining a civic‐minded elite because elites have the power and motivation to enrich themselves at the expense of the rest of us. For the sufficientarian story to work, we need more that explains the realistic possibility of a benevolent ruling elite, until then, democratic equality seems to be better realized by aiming for equal educations, adequacy isn't enough.

Some political philosophers have recently argued that providing K–12 students with an adequate education suffices for social justice in education provided that the threshold of educational adequacy is properly understood. Others have argued that adequacy is insufficient for social justice. In this article I side with the latter group. I extend this debate to racial inequality in education by considering the controversial practice of paying students cash for grades to close the racial achievement gap. I then argue that (...) framing the demand for racial justice in education solely in terms of educational adequacy leaves us unable to take issue with the cash for grades policy as a matter of principle. While this does not entail that educational adequacy is unimportant, it adds to the general case for why adequacy does not suffice for social justice. (shrink)

Resemblance Nominalism About Perfect Naturalness is the view that perfect naturalness of classes is best defined by a conceptual primitive of resemblance between particulars. The adequacy of RNPN is defended by outlining nominalism as the strictly anti-constitutive view that the particulars’ being the fundamental ways they are is not constituted by anything further, supplying a doubly plural contrastive and graded resemblance predicate that allows for a definition of perfect naturalness on an actualist basis, and proving a representation and a (...) uniqueness theorem on the basis of a formal constraint on resemblance called “the Principle”, thereby revealing that bodies of nominalist resemblance facts are guaranteed to behave as if they were grounded in patterns of universals distributed over particulars.

The article explores a gradual refinement of the notion of reflection in Husserlian phenomenology. In his early period, Husserl takes phenomenological reflection to attain adequate evidence, since its object is self-given in an absolute and complete manner. However, this conception of reflection does not remain unchanged. Husserl later realizes that immanent perception or phenomenological reflection also involves a certain horizonality and naivety that has to do with its temporal nature and must be queried in a further critical, apodictic reflection. Focusing (...) more on the notion of apodicticity than adequacy, Husserl subsequently ascribes a new methodological role to reflection: instead of a mere epistemic warrant that guarantees for us the ultimate truth of our experiential life once and for all, phenomenological reflection ensures the strictness of phenomenology insofar as it entails an ethical-existential dimension as the norm of a life-form where the subject pursues full self-understanding and self-justification.

Food security scholarship and policy tends to embrace the nutrition status of individual men, women and children as the end-goal of food security efforts. While there has been much value in investigating and trying to ensure sufficient nutrition for struggling households around the world, this overriding emphasis on nutrition status has reduced our understandings of what constitutes food adequacy. While token attention has been paid to more qualitative ideas like “cultural appropriateness,” food security scholars and policy makers have been (...) unable to understand the broader value of food, which exceeds its caloric and nutrient counts. Drawing on empirical work from Medellín, Colombia, the paper argues that having adequate food means much more than simply sufficient nutrient intake, perhaps especially among marginalized groups. Exploring the case of food insecure women from Colombia who were forcibly displaced from rural to urban, we demonstrate how understandings of food adequacy must consider the social and environmental imaginaries of marginalized groups.

This paper provides a unifying axiomatic account of the interpretation of recursive types that incorporates both domain-theoretic and realizability models as concrete instances. Our approach is to view such models as full subcategories of categorical models of intuitionistic set theory. It is shown that the existence of solutions to recursive domain equations depends upon the strength of the set theory. We observe that the internal set theory of an elementary topos is not strong enough to guarantee their existence. In contrast, (...) as our first main result, we establish that solutions to recursive domain equations do exist when the category of sets is a model of full intuitionistic Zermelo–Fraenkel set theory. We then apply this result to obtain a denotational interpretation of FPC, a recursively typed lambda-calculus with call-by-value operational semantics. By exploiting the intuitionistic logic of the ambient model of intuitionistic set theory, we analyse the relationship between operational and denotational semantics. We first prove an “internal” computational adequacy theorem: the model always believes that the operational and denotational notions of termination agree. This allows us to identify, as our second main result, a necessary and sufficient condition for genuine “external” computational adequacy to hold, i.e. for the operational and denotational notions of termination to coincide in the real world. The condition is formulated as a simple property of the internal logic, related to the logical notion of 1-consistency. We provide useful sufficient conditions for establishing that the logical property holds in practice. Finally, we outline how the methods of the paper may be applied to concrete models of FPC. In doing so, we obtain computational adequacy results for an extensive range of realizability and domain-theoretic models. (shrink)

This essay provides evidence to support a promising conceptual and potentially practical set of ideas at once both principled and effective found in the work of Max Weber and Alfred Schutz addressed to the issue of ‘adequacy’ as a goal in social research. Efforts to achieve adequacy beyond the epistemological conditions required by Weber’s demand that evidence meet both causal adequacy and adequacy on the level of meaning were significantly refocused by Schutz’s later concern, responding specifically (...) to Weber, that the social sciences also address themselves to his postulate of adequacy. It states that “Each term used in a scientific system referring to human action must be so constructed that a human act performed within the life-world by an individual actor in the way indicated by the typical construction would be reasonable and understandable for the actor himself, as well as for his fellow men”. A serious attempt to implement a more expansive notion of adequacy by practically activating this postulate in the ways suggested can be beneficial not only for the social research situation but in everyday life as well.

In the present paper, I analyze the complex relationship of tension between Critical Theory and phenomenology from a sociological-theoretical perspective. I start from two theses. The first one is that one of the primary reasons for the antagonism between these two paradigms lies in their ideal-typically opposed assessments of the role of ‘meaning-adequacy’ in social research. The second one is that in recent years, there has been a strong rapprochement of Critical Theory with (social) phenomenology. This shift, fundamentally embodied (...) in Hartmut Rosa’s work, can be understood as the culminating point of a progressive turn towards meaning-adequacy within the Frankfurt School. In order to unfold these two theses, I will proceed in three steps. First (1), I will present the main outlines of the relationship of tension between the two traditions from both a historico-intellectual and a systematic perspective. Second (2), I will focus on the contemporary readings of the Schutzian notion of ‘meaning-adequacy’ and discuss their value for better understanding the historical opposition between the two paradigms, as well as their recent rapprochement. Third (3), I will sketch the key features of Rosa’s sociology of world-relations, understood as a phenomenological Critical Theory that shows a strong commitment to a radicalized version of the meaning-adequacy postulate.

According to an adequacy-for-purpose view, models should be assessed with respect to their adequacy or fitness for particular purposes. Such a view has been advocated by scientists and philosophers...

We critically engage two traditional views of scientific data and outline a novel philosophical view that we call the pragmatic-representational view of data. On the PR view, data are representations that are the product of a process of inquiry, and they should be evaluated in terms of their adequacy or fitness for particular purposes. Some important implications of the PR view for data assessment, related to misrepresentation, context-sensitivity, and complementary use, are highlighted. The PR view provides insight into the (...) common but little-discussed practices of iteratively reusing and repurposing data, which result in many datasets’ having a phylogeny—an origin and complex evolutionary history—that is relevant to their evaluation and future use. We relate these insights to the open-data and data-rescue movements, and highlight several future avenues of research that build on the PR view of data. (shrink)

I show that extant attempts to capture and generalize empirical adequacy in terms of partial structures fail. Indeed, the motivations for the generalizations in the partial structures approach are better met by the generalizations via approximation sets developed in “Generalizing Empirical Adequacy I”. Approximation sets also generalize partial structures.

David Lewis's modal realism claims that nothing can exist in more than one world or time, and that statements about how something would have been are to be analysed in terms of its counterpart. I first explain why the counterpart relation depends on de re modal statements in an intensional language, so that intuitive properties of similarity relations cannot be used to show that the counterpart relation is not an equivalence relation. I then look at test sentences in (the intensional) (...) natural language, and show that none of them provide compelling evidence that a counterpart semantics is needed. (shrink)

In their chapter “Knowledge, Practical Adequacy, and Stakes,” Charity Anderson and John Hawthorne present several challenges to the doctrine of pragmatic encroachment. In this brief reply to their chapter two things are aimed at. First, the chapter argues that there is a sense in which their case against pragmatic encroachment is a bit weaker, and another sense in which that case is much stronger, than Anderson and Hawthorne’s own argument would suggest. Second, the chapter highlights and then builds upon (...) their extremely interesting reflections on one sort of practical matter that has not received proper attention in the literature: the epistemic significance of double-checking. This is done with an eye towards pointing in the direction of further work. (shrink)

In the Periodic Tables the transition from atoms to double-charged cations is accompanied by alterations in the composition of s and p blocks and reciprocal location of blocks, as well as by changes in the composition and length of periods. We have previously described the relationship between the atom properties and the total number of differentiating electrons. This paper demonstrates that, despite the above transition-related alterations, this relationship is also valid for the description of the properties of double-charged cations. This (...) can be exemplified by the dependence of the ionization energy on the total number of p electrons in p block, d electrons in d block, and f electrons in f block. Furthermore, a single periodic equation is sufficient for the description of properties of all of double-charged cations from each block. (shrink)

In this paper I make a contribution to three distinct, but deeply interwoven subjects. Firstly, I argue that, at the level of ideal theory, the distribution of educational goods should follow a sufficientarian pattern and that the evaluative space of children’s advantage should be inspired by the capability approach. Secondly, the paper is delving into the more policy-oriented debates on the desirability of school choice. I argue that, given the non-ideal circumstances in which decision makers have to act, giving parents (...) the opportunity to choose the school for their children is a sine qua non condition for even approaching the ideals of sufficientarian justice. Lastly, I move the discussion on more empirical grounds, advancing a criticism of the Romanian educational legislation. I argue that the sufficiency-constrained school choice system that I envision could solve some of the problems that the Romanian educational system faces today. (shrink)

he notion of linguistic adequacy (the adequacy of sentences to express or describe) is explicated in terms of a set theoretical model of the communication situation. Roughly: a message is adequate to the degree it answers the receiver's questions. Adequacy is distinguished from openness, in such a way that a message can be both completely adequate in a communication event and also “inexhaustibly open”;. Using this explication it is possible to translate and clarify several familiar philosophical theses (...) concerning the adequacy of language. The view that “humanistic”; language differs from scientific language is clarified and criticized. Seven types of empirical test of the explication are discussed. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Anthony Paul Kerby THE ADEQUACY OF SELF-NARRATION: A HERMENEUTICAL APPROACH An important question that arises from the increasing contemporary emphasis on the self as a narrative construct concerns the adequacy or truthfulness of the narrative accounts we give ofourselves. What, for example, stops our self-narrations and self-characterizations from becoming, in many cases, mere flights of fancy or fictions? If, on a fairly radical view, the self is (...) taken to be a product of narrative emplotment, then clearly the above question cannot be answered by a simple appeal to what the narrative is supposed to represent or copyas though the selfwere first given to us external or prior to the narrative. It is not immediately clear, however, just what a narrative account of the human subject could be adequate to, and, if we were to grant some prenarrative status to the human subject, it is also not clear whether the imposition of narrative structures falsifies the "truth" of this latter subject. What we shall examine, then, is precisely this important question of adequacy and various problems that surround it. To bring these problems into focus and offer some solutions, we shall consider both self-narration and the writing of history. These solutions will have a decidedly hermeneutical flavor, and for one principal reason: hermeneutics, especially as represented by Gadamer and Ricoeur, is particularly suited to addressing questions of self-expression while avoiding traditional metaphysical presuppositions about the human subject. Let us begin with a few words on hermeneutics. To offer a hermeneutics of something will presumably commit one to certain philosophical and methodological presuppositions. To see what these presuppositions are we might briefly compare hermeneutics to two of its close neighbors: phenomenology and semiotics. I believe 232 Anthony Paul Kerby233 diät these three positions are all of value and that their central insights must be integrated. Contemporary hermeneutics can be viewed as usefully fulfilling this latter task. On the one hand, a hermeneutic philosophy can accept the phenomenological starting point of immediacy to phenomena. However, it does not delude itself into thinking that there is a privileged mode of access to phenomena that would disconnect the categories of our particular historical and linguistic heritage. On the other hand, while recognizing that our understanding is mediated by language and semiotic systems generally—the signifying networks of exchange and communication—hermeneutics need notlose contactwith the life-experiences of the subjects within this semiotic realm. That is, we not only come to understand the sign systems operative in our world, but also, to some degree, ourselves as we act in and through them. As Ricoeur often stresses, semiotics (and structuralism) have still to take the final step of accounting for the experiencing subjects presupposed by any structural social system. Semiotics would, at its extreme point, remain arbitrary with respect to phenomenological experience, just as phenomenology would remain silent if it were consistendy to avoid the conceptual and cultural biases of our languages. Thus, while presupposing individual human experience (and worldliness ), hermeneutics can still accept that such experience only achieves expression and explicit understandingin the semiotic realm, and further that this expression is not the duplication of a fully formed but preexpressed understanding, for understanding is only first grasped at the level of expression. As Gadamer has written: "Being that can be understood is language," but this is not to deny the existence of some matter at hand, a hermeneutic Sache selbst, that thereby comes to language ; in our case the human subject itself. Hermeneutics is essentially a reflexive philosophy, but one which rejects the absolute starting point of the Cartesian subject. The subject's self-understanding is an interpretive process, where we must recognize interpretation as an integral part of the subject's very being. Charles Taylor sums up this hermeneutic situation by saying that man "cannot be understood simply as an object among objects, for his life incorporates an interpretation, an expression of which cannot exist unexpressed, because the self that is to be interpreted is essentially that of a being who self-interprets." ' This position, which implies a rejection of both subjectivism and die metaphysics of presence, problematizes self-understanding by viewing the self as mediated by its... (shrink)

A central component to scientific practice is the construction and use of scientific models. Scientists believe that the success of a model justifies making claims that go beyond the model itself. However, philosophical analysis of models suggests that drawing inferences about the world from successful models is more complex. In this dissertation I develop a framework that can help disentangle the related strands of evaluation of model success, model extendibility, and the ability to draw ampliative inferences about the world from (...) models. I present and critically assess two leading accounts of model assessment, arguing that neither is sufficient to provide a complete understanding of model evaluation. I introduce a more powerful framework incorporating elements of the two views, which can help answer these three questions: What is the target of evaluation in model assessment? How does that evaluation proceed? What licenses us in making inferences about the real world, based on the evaluation of our models as successful? The framework identifies two distinct targets of model evaluation: representational similarity between the model and target system, and the adequacy of the model as a tool to answer questions. Both assessments must be relativized to a purpose, of which there are three general kinds: descriptive, predictive, and explanatory. These purposes differ in the way they inform the similarity relation, which is relevant for the similarity assessment, and the output they produce, which is relevant for the adequacy assessment. Any model can be assessed relative to any purpose, however a model encodes certain decisions made during the model’s construction, which impact its ability to be applied to a new purpose or new domain. My framework shows that extending a model, and drawing inferences from it, depends on its representational similarity. I apply this framework to several examples taken from astrophysics showing in detail how it can help illuminate the structure of the models, as well as make the justification for inferences made from them clear. The final chapter is a detailed analysis of a contemporary debate surrounding the use of models in astrophysics, between proponents of MOND and the standard ΛCDM model. (shrink)

In his book, The Scientific Image, Bas van Fraassen argues for an anti-realist view of science according to which the sole epistemological aim of science is to "save the phenomena". As originally conceived, his constructive empiricism is strongly extensional, but in his account of the empirical adequacy of probabilistic theories, van Fraassen reluctantly abandons this extensional position, arguing that modal (intensional) notions are unavoidable in interpreting probability. I argue in this paper that van Fraassen has not presented the strongest (...) possible case for a fully extensional account of empirical adequacy. On the present account, a probabilistic theory is empirically adequate just in case there is no theory that has a higher likelihood relative to all the phenomena in the actual world. I prove that a theory is empirically adequate if and only if the probability attributed to each observable event that occurs in the actual world is its limiting relative frequency. Thus, in so far as one is concerned with the empirical adequacy (rather than with the literal truth) of probabilistic theories, strict relative frequencies provide an adequate basis for "interpreting probability". Probabilistic theories are treated in a genuine measurement context. In this connection I distinguish between worlds that are "strongly infinite" and worlds that are only "weakly infinite". It is characteristic of the former worlds that there is no limit to the precision of actual measurements. I show by example that in some "strongly infinite" worlds, theories will be empirically adequate only if observables are represented by continuous (rather than discrete) random variables. The range of such examples is clarified by a theorem which states necessary and sufficient conditions under which the "phenomena can be saved" without recourse to continuous random variables and real numbers.

Standard possible world semantics for propositional modal languages ignore truth-value gaps. However, simple considerations suggest that it should not be so. In Section 1, I identify what I take to be a correct truth-clause for necessity under the assumption that some possible worlds are incomplete (i.e., "at" which some propositions lack a truth-value). In Section 2, I build a world semantics, the semantics of TV-models, for standard modal propositional languages, which agrees with the truth-clause for necessity previously identified. Sections 3–5 (...) are devoted to systematic concerns. In particular, in Section 4, Prior’s system Q (propositional version) is given a TV-models semantics and proved adequate (i.e., sound and complete) with respect to it. (shrink)

Genetic research presents ethical challenges to the achievement of valid informed consent, especially in developing countries with areas of low literacy. During the last several years, a number of genetic research proposals involving Omani nationals were submitted to the Department of Research and Studies, Ministry of Health, Oman.The objective of this paper is to report on the results of an internal quality assurance initiative to determine the extent of the information being provided in genetic research informed consent forms. In order (...) to achieve this, we developed checklists to assess the inclusion of basic elements of informed consent as well as elements related to the collection and future storage of biological samples. Three of the authors independently evaluated and reached consensus on seven informed consent forms that were available for review.Of the seven consent forms, four had less than half of the basic elements of informed consent. None contained any information regarding whether genetic information relevant to health would be disclosed, whether participants may share in commercial products, the extent of confidentiality protections, and the inclusion of additional consent forms for future storage and use of tissue samples. Information regarding genetic risks and withdrawal of samples were rarely mentioned (1/7), whereas limits on future use of samples were mentioned in 3 of 7 consent forms.Ultimately, consent forms are not likely to address key issues regarding genetic research that have been recommended by research ethics guidelines. We recommend enhanced educational efforts to increase awareness, on the part of researchers, of information that should be included in consent forms. (shrink)

Some theorists argue that rather than advocating a principle of educational equality as a component of a theory of justice in education, egalitarians should adopt a principle of educational adequacy. This paper looks at two recent attempts to show that adequacy, not equality, constitutes justice in education.

It also argues (...) that a principle of educational adequacy cannot be all there is to justice in education. (shrink)
