Invariance criteria are widely accepted as a means to demarcate the logical vocabulary of a language. In previous work, I proposed a framework of “semantic constraints” for model theoretic consequence which does not rely on a strict distinction between logical and nonlogical terms, but rather on a range of constraints on models restricting the interpretations of terms in the language in different ways. In this paper I show how invariance criteria can be generalized so as to (...) apply to semantic constraints on models. Some obviously unpalatable semantic constraints turn out to be invariant under isomorphisms. I shall connect our discussion to known counterexamples to invariance criteria for logical terms, and so the generalization will also shed light on the current existing debate on logicality. I analyse the failure of invariance to fulfil its role as a criterion for logicality, and argue that invariance conditions should best be thought of as merely methodological meta-constraints restricting the ways the model-theoretic apparatus should be used.

This is a survey of work on set-theoretical invariance criteria for logicality. It begins with a review of the Tarski-Sher thesis in terms, first, of permutation invariance over a given domain and then of isomorphism invariance across domains, both characterized by McGee in terms of definability in the language L∞,∞. It continues with a review of critiques of the Tarski-Sher thesis, and a proposal in response to one of those critiques via homomorphism invariance. That has (...) quite divergent characterization results depending on its formulation, one in terms of FOL, the other by Bonnay in terms of L∞,∞, both without equality. From that we move on to a survey of Bonnay’s work on similarity relations between structures and his results that single out invariance with respect to potential isomorphism among all such. Turning to the critique that calls for sameness of meaning of a logical operation across domains, the paper continues with a result showing that the isomorphism invariant operations that are absolutely definable with respect to KPU−Inf are exactly those definable in full FOL; this makes use of an old theorem of Manders. The concluding section is devoted to a critical discussion of the arguments for set-theoretical criteria for logicality. (shrink)

I argue that in order to apply the most common type of criteria for logicality, invariance criteria, to natural language, we need to consider both invariance of content—modeled by functions from contexts into extensions—and invariance of character—modeled, à la Kaplan, by functions from contexts of use into contents. Logical expressionsshould be invariant in both senses. If we do not require this, then old objections due to Timothy McCarthy and William Hanson, suitably modified, demonstrate that content (...) invariant expressions can display intuitive marks of non-logicality. If we do require this, we neatly avoid these objections while also managing to demonstrate desirable connections of logicality to necessity. The resulting view is more adequate as a demarcation of the logical expressions of natural language. (shrink)

What is a logical constant? The question is addressed in the tradition of Tarski's definition of logical operations as operations which are invariant under permutation. The paper introduces a general setting in which invariance criteria for logical operations can be compared and argues for invariance under potential isomorphism as the most natural characterization of logical operations.

Scientific knowledge should not only be true, it should be as objective as possible. It should refer to a reality independent of any subject. What can we use as a criterion of objectivity? Intersubjectivity (i.e., intersubjective understandability and intersubjective testability) is necessary, but not sufficient. Other criteria are: independence of reference system, independence of method, non-conventionality. Is there some common trait? Yes, there is: invariance under some specified transformations. Thus, we say: A proposition is objective only if its (...) truth is invariant against a change in the conditions under which it was formulated. We give illustrations from geometry, perception, neurobiology, relativity theory, and quantum theory. Such an objectivist position has many advantages. (shrink)

This volume is presented in honour of Heinz Post, who founded a distinc tive and distinguished school of philosophy of science at Chelsea College, University of London. The 'Chelsea tradition' in philosophy of science takes the content of science seriously, as exemplified by the papers presented here. The unifying theme of this work is that of 'Correspondence, Invariance and Heuristics', after the title of a classic and seminal paper by Heinz Post, published in 1971, which is reproduced in this (...) volume with the kind permission of the editors and publishers of Studies in History and Philosophy of Science. Described by Paul Feyerabend in Against Method as "brilliant" and " . . . a partial antidote against the view which I try to defend" (1975, p. 61, fn. 17), this paper, peppered with illustrative examples from the history of science, brings to the fore some of Heinz Post's central concerns: the heuristic criteria used by scientists in constructing their theories, the intertheoretic relationships which these criteria reflect and, in particular, the nature of the correspondence that holds between a theory and its predecessors (and its suc cessors). The appearance of this volume more than twenty years later is an indica tion of the fruitfulness of Post's contribution: philosophers of science continue to explore the issues raised in his 1971 paper.

Metaphysicians who are aware of modern physics usually follow Putnam (1967) in arguing that Special Theory of Relativity is incompatible with the view that what exists is only what exists now or presently. Partisans of presentism (the motto ‘only present things exist’) had very difficult times since, and no presentist theory of time seems to have been able to satisfactorily counter the objection raised from Special Relativity. One of the strategies offered to the presentist consists in relativizing existence to inertial (...) frames. This unfashionable strategy has been accused of counterfeiting, since the meaning of the concept of existence would be incompatible with its relativization. Therefore, existence could only be relativistically invariant. In this paper, I shall examine whether such an accusation hits its target, and I will do this by examining whether the different criteria of existence that have been suggested by the Philosophical Tradition from Plato onwards imply that existence cannot be relativized.

This collection of new essays presents cutting-edge research on the semantic conception of logic, the invariance criteria of logicality, grammaticality, and logical truth. Contributors explore the history of the semantic tradition, starting with Tarski, and its historical applications, while central criticisms of the tradition, and especially the use of invariance criteria to explain logicality, are revisited by the original participants in that debate. Other essays discuss more recent criticism of the approach, and researchers from mathematics and (...) linguistics weigh in on the role of the semantic tradition in their disciplines. This book will be invaluable to philosophers and logicians alike. (shrink)

This paper develops an account of explanation in biology which does not involve appeal to laws of nature, at least as traditionally conceived. Explanatory generalizations in biology must satisfy a requirement that I call invariance, but need not satisfy most of the other standard criteria for lawfulness. Once this point is recognized, there is little motivation for regarding such generalizations as laws of nature. Some of the differences between invariance and the related notions of stability and resiliency, (...) due respectively to Sandra Mitchell and Brian Skyrms, are explored. (shrink)

In Recent years noncognitivist ethical theories have been supported by an argument which has come to be widely accepted among moral philosophers.1 According to this argument, an ethical term like ‘good’ has both a commending function and a describing function, but between these functions there is the important difference that the commending function alone is invariant while the describing function varies greatly. For many and different things may be called good—hammers, sunsets, paintings, missionaries, cannibals—but despite these differences in the descriptive (...) criteria for applying the word to objects, ‘good’ retains a common meaning in all these uses, for in each case the word is being used to commend. The conclusion drawn, then, is that because of its being the sole invariant or common feature of every use of ‘good’, the commendatory function rather than the varying descriptive function must be the primary meaning of ‘good’. I shall refer to this as the commendatory invariance argument. (shrink)

Filling out long questionnaires can be frustrating, unpleasant, and discouraging for respondents to continue. This is why shorter forms of long instruments are preferred, especially when they have comparable reliability and validity. In present study, two short forms of the Cross-cultural Personality Assessment Inventory were developed and validated. The items of the short forms were all selected from the 28 personality scales of the CPAI-2 based on the norm sample. Based on some priori criteria, we obtained the appropriate items (...) and constructed the 56-item Chinese Personality Assessment Inventory and the 28-item CPAI. Then, we examined the factor structure of both short forms with Exploratory SEM and replicated the four-factor structure of the original CPAI-2, reflecting the four personality domains of Chinese people, namely, Social Potency, Dependability, Accommodation, and Interpersonal Relatedness. Further analyses with ESEM models demonstrate full measurement invariance across gender for both short forms. The results show that females score lower than males on Social Potency. In addition, these four factors of both short forms have adequate internal consistency, and the correlation patterns of the four factors, the big five personality traits, and several health-related variables are extremely similar across the two short forms, reflecting adequate and comparable criterion validity, convergent validity, and discriminant validity. Overall, the short versions of CPAI-2 are psychometrically acceptable and have practically implications for measuring Chinese personality and cross-cultural research. (shrink)

In standard model-theoretic semantics, the meaning of logical terms is said to be fixed in the system while that of nonlogical terms remains variable. Much effort has been devoted to characterizing logical terms, those terms that should be fixed, but little has been said on their role in logical systems: on what fixing their meaning precisely amounts to. My proposal is that when a term is considered logical in model theory, what gets fixed is its intension rather than its extension. (...) I provide a rigorous way of spelling out this idea, and show that it leads to a graded account of logicality: the less structure a term requires in order for its intension to be fixed, the more logical it is. Finally, I focus on the class of terms that are invariant under isomorphisms, as they render themselves more easily to mathematical treatment. I propose a mathematical measure for the logicality of such terms based on their associated Löwenheim numbers. (shrink)

Many recent writers in the philosophy of mathematics have put great weight on the relative categoricity of the traditional axiomatizations of our foundational theories of arithmetic and set theory. Another great enterprise in contemporary philosophy of mathematics has been Wright's and Hale's project of founding mathematics on abstraction principles. In earlier work, it was noted that one traditional abstraction principle, namely Hume's Principle, had a certain relative categoricity property, which here we term natural relative categoricity. In this paper, we show (...) that most other abstraction principles are not naturally relatively categorical, so that there is in fact a large amount of incompatibility between these two recent trends in contemporary philosophy of mathematics. To better understand the precise demands of relative categoricity in the context of abstraction principles, we compare and contrast these constraints to stability-like acceptability criteria on abstraction principles, the Tarski-Sher logicality requirements on abstraction principles studied by Antonelli and Fine, and supervaluational ideas coming out of Hodes' work.

The article deals with the problematic aspects of the concept of identity, the analysis of which helps to point out and to overcome the paradoxes of the “diachronic identity”, the identity of the human person (as identity of its inner cell) and “plural, flexible identity”, and also to clarify the conditions of the legitimate use of these concepts in contemporary philosophy and social science. The article examines two paradigms of identity: the substantive, when the identity of a thing is sought (...) in an invariable property, which provides its synchronous identity, and the formal, when the identity is sought in a form, a structure of the language, which provides its duration in time and helps to understand the diachronic identity. The article shows the importance of the use of “criteria of identity”, introduced by analytical philosophers to find out the way of duration in time of beings which they try to identify, from the material objects to the collective beings, including the identity of the human person. The problem of subjective identity is pointed out as a separate problem. Two main approaches to it are differentiated: mentalist and expressivist. The first is focused on the inner world of the human being, its memories and feelings, creating paradoxes of the «identity for itself» which is not the «identity for the others», whereas the second lets include the social world in the definition of the subjective identity and facilitates the reconsideration of the boundaries of the internal and the external in determining the human self. The article analyses contemporary use of the concept of identity in social science and public discourses and demonstrates the contradiction of the concept of “plural, heterogeneous identity”, which formulates but doesn’t solve the problem of the subjective identity as the identification of an individual with different social groups.

This paper deals with the adequacy of the model-theoretic definition of logical consequence. Logical consequence is commonly described as a necessary relation that can be determined by the form of the sentences involved. In this paper, necessity is assumed to be a metaphysical notion, and formality is viewed as a means to avoid dealing with complex metaphysical questions in logical investigations. Logical terms are an essential part of the form of sentences and thus have a crucial role in determining logical (...) consequence. Gila Sher and Stewart Shapiro each propose a formal criterion for logical terms within a model-theoretic framework, based on the idea of invariance under isomorphism. The two criteria are formally equivalent, and thus we have a common ground for evaluating and comparing Sher and Shapiro philosophical justification of their criteria. It is argued that Shapiro's blended approach, by which models represent possible worlds under interpretations of the language, is preferable to Sher’s formal-structural view, according to which models represent formal structures. The advantages and disadvantages of both views’ reliance on isomorphism are discussed. (shrink)

This paper partly answers the question “what a frame may be exactly like when it characterizes a pretabular logic in NExtK4”. We prove the pretabularity crieria for the logics of finite depth in NExtK4. In order to find out the criteria, we create two useful concepts—“pointwise reduction” and “invariance under pointwise reductions”, which will remain important in dealing with the case of infinite depth.

Assuming the existence of a monster model, tameness, and continuity of nonsplitting in an abstract elementary class (AEC), we extend known superstability results: let $\mu>\operatorname {LS}(\mathbf {K})$ be a regular stability cardinal and let $\chi $ be the local character of $\mu $ -nonsplitting. The following holds: 1.When $\mu $ -nonforking is restricted to $(\mu,\geq \chi )$ -limit models ordered by universal extensions, it enjoys invariance, monotonicity, uniqueness, existence, extension, and continuity. It also has local character $\chi $. This (...) generalizes Vasey’s result [37, Corollary 13.16] which assumed $\mu $ -superstability to obtain same properties but with local character $\aleph _0$.2.There is $\lambda \in [\mu,h(\mu ))$ such that if $\mathbf {K}$ is stable in every cardinal between $\mu $ and $\lambda $, then $\mathbf {K}$ has $\mu $ -symmetry while $\mu $ -nonforking in (1) has symmetry. In this case:(a) $\mathbf {K}$ has the uniqueness of $(\mu,\geq \chi )$ -limit models: if $M_1,M_2$ are both $(\mu,\geq \chi )$ -limit over some $M_0\in K_{\mu }$, then $M_1\cong _{M_0}M_2$ ;(b)any increasing chain of $\mu ^+$ -saturated models of length $\geq \chi $ has a $\mu ^+$ -saturated union. These generalize [31] and remove the symmetry assumption in [10, 38].Under $(<\mu )$ -tameness, the conclusions of (1), (2)(a)(b) are equivalent to $\mathbf {K}$ having the $\chi $ -local character of $\mu $ -nonsplitting.Grossberg and Vasey [18, 38] gave eventual superstability criteria for tame AECs with a monster model. We remove the high cardinal threshold and reduce the cardinal jump between equivalent superstability criteria. We also add two new superstability criteria to the list: a weaker version of solvability and the boundedness of the U-rank. (shrink)

This article points out the criteria necessary in order for a qualitative scientific method to qualify itself as phenomenological in a descriptive Husserlian sense. One would have to employ description within the attitude of the phenomenological reduction, and seek the most invariant meanings for a context. The results of this analysis are used to critique an article by Klein and Westcott , that presents a typology of the development of the phenomenological psychological method.

This paper discusses several distinct process theories of causality offered in recent years by Phil Dowe and me. It addresses problems concerning the explication of causal process, causal interaction, and causal transmission, whether given in terms of transmission of marks, transmission of invariant or conserved quantities, or mere possession of conserved quantities. Renouncing the mark-transmission and invariant quantity criteria, I accept a conserved quantity theory similar to Dowe's--differing basically with respect to causal transmission. This paper also responds to several (...) fundamental constructive criticisms contained in Christopher Hitchcock's discussion of both the mark-transmission and the conserved quantity theories.

Examines the relevance of empirical studies of responsibility judgments for traditional philosophical concerns about free will and moral responsibility. We argue that experimental philosophy is relevant to the traditional debates, but that setting up experiments and interpreting data in just the right way is no less difficult than negotiating traditional philosophical arguments. Both routes are valuable, but so far neither promises a way to secure significant agreement among the competing parties. To illustrate, we focus on three sorts of issues. For (...) illustration, we discuss an error theory for incompatibilist intuitions proposed by Eddy Nahmias and colleagues, the role that empirical studies might have in the assessment of manipulation arguments for incompatibilism, and the suggestion that empirical studies reveal that core criteria for moral responsibility ought not to be applied invariantly across different sorts of cases.

This article examines the role of experimental generalizations and physical laws in neuroscientific explanations, using Hodgkin and Huxley’s electrophysiological model from 1952 as a test case. I show that the fact that the model was partly fitted to experimental data did not affect its explanatory status, nor did the false mechanistic assumptions made by Hodgkin and Huxley. The model satisfies two important criteria of explanatory status: it contains invariant generalizations and it is modular (both in James Woodward’s sense). Further, (...) I argue that there is a sense in which the explanatory heteronomy thesis holds true for this case. †To contact the author, please write to: SNF‐Professorship for Philosophy of Science, University of Basel, Missionsstrasse 21, 4003 Basel, Switzerland; e‐mail: [email protected].

Many philosophical accounts of the emotions conceive of them as susceptible to assessments of rationality, fittingness, or some other notion of aptness. Analogous assumptions apply in cases of emotions directed at what are taken to be only fictional or only imagined. My question is whether the criteria governing the aptness of emotions we have toward what we take to be real things apply invariantly to those emotions we have toward what we take to be only fictional or imagined. I (...) argue that what counts as a reason justifying an emotion can differ across real, fictional, and imagined domains. (shrink)

No comprehensive theory of development is available yet. Traditionally, we regard the development of animals as a sequence of changes through which an adult multicellular animal is produced, starting from a single cell which is usually a fertilized egg, through increasingly complex stages. However, many phenomena that would not qualify as developmental according to these criteria would nevertheless qualify as developmental in that they imply nontrivial (e.g., non degenerative) changes of form, and/or substantial changes in gene expression. A broad, (...) comparative approach is badly needed. In the Cnidaria, for example, even the boundary between generations is problematic. Describing their life cycle in terms of metagenesis (alternation between polyp generation and medusa generation) or in terms of metamorphosis (polyp as larva or juvenile) are matters of semantics more than biology. The life cycle of other metazoans, described in textbooks in terms of larva-to-adult metamorphosis, is hardly different from a typical metagenetic life cycle of cnidarians. This applies to holometabolous insects and to marine invertebrates like sea urchins, where most of the larval cells are discarded at metamorphosis. The uncertain temporal and spatial boundaries of individual development are also shown by the widespread lack of a strict correspondence between adult and mature. A comprehensive theory of development should start with a zero principle of “developmental inertia,” corresponding to an indeterminate local self-perpetuation of cell-level dynamics. Indeterminate growth, scale-invariance, segmentation, and regeneration provide examples of developmental dynamics close to that. (shrink)

>With assets of over US$1.0 trillion and growing, public pension funds in the United States have become a major force in the private sector through their holding of equity positions in large publicly traded corporations. More recently, these funds have been expanding their investment strategy by considering a corporations long-term risks on issues such as environmental protection, sustainability, and good corporate citizenship, and how these factors impact a companys long-term performance. Conventional wisdom argues that the fiduciary responsibility of the pension (...) funds trustees must be solely focused on their beneficiaries and, therefore, their investment criteria must be based strictly on narrowly defined financial measures. It is also asserted that well-established financial measurements of corporate performance already include long-term risk assessment through discounted present value of future flow of earnings. Consequently, all other criteria are contrary to the best interest of the pension funds beneficiaries. In this paper, we assert that, contrary to conventional wisdom, pension funds, and for that matter other mutual funds, must be concerned with the long-term survival and growth of corporations. These measures are generally referred to socially responsible investing (SRI) and when applied to corporations, it is termed socially responsible corporate conduct (SRCC). We demonstrate that current measurement of future risk assessment invariably understates, and quite often completely overlooks, these long-term risks because of the inherent bias towards short-run on the part of financial intermediaries whose compensation depends greatly on short-term results. Furthermore, there is ample evidence to suggest that these intermediaries have been engaging in self-serving practices and thus failing in their duties to serve their clients, i.e. pension funds, best interests. Because of their large holdings in the total market as well as individual companies, these funds cannot easily divest from poorly performing companies without destabilizing the companies stock and overall markets. Hence, they must opt for a strategy of emphasizing investment criteria that encourage companies to take into account long-term aspects of their operations in terms of their impact on environment, sustainability, and community welfare, to name a few. We argue that an exclusionary, and even a primary, focus on short-term financial criteria is no longer a viable option. It also calls for the pension funds to encourage greater transparency and accountability of the entire corporate sector through improved corporate governance. Thus socially responsible investing practices are not merely discretionary and desirable activities; they are a necessary imperative, which both the corporations and public pension funds, and other large institutional holders, will ignore at serious peril to themselves. Finally, the paper considers some of the recent developments where corporations have been responding to these challenges and how their actions might be strengthened through greater disclosure and transparency of corporate activities. It also makes recommendations for the pension funds to support further research in creating new measurement standards that further refine the concept of socially responsible investing as a necessary ingredient of long-term corporate survival and growth in the context of a changing economic, environmental and socio-political dynamic.

David Malament's (1977) well-known result, which is often taken to show the uniqueness of the Poincare-Einstein convention for defining simultaneity, involves an unwarranted physical assumption: that any simultaneity relation must remain invariant under temporal reflections. Once that assumption is removed, his other criteria for defining simultaneity are also satisfied by membership in the same backward (forward) null cone of the family of such cones with vertices on an inertial path. What is then unique about the Poincare-Einstein convention is that (...) it is independent of the choice of inertial path in a given inertial frame, confirming a remark in Einstein 1905. Similarly, what is unique about the backward (forward) null cone definition is that it is independent of the state of motion of an observer at a point on the inertial path. (shrink)

Medical terminology collects and organizes the many different kinds of terms employed in the biomedical domain both by practitioners and also in the course of biomedical research. In addition to serving as labels for biomedical classes, these names reflect the organizational principles of biomedical vocabularies and ontologies. Some names represent invariant features (classes, universals) of biomedical reality (i.e., they are a matter for ontology). Other names, however, convey also how this reality is perceived, measured, and understood by health professionals (i.e., (...) they belong to the domain of epistemology). We analyze terms from several biomedical vocabularies in order to throw light on the interactions between ontological and epistemological components of these terminologies. We identify four cases: 1) terms containing classification criteria, 2) terms reflecting detectability, modality, uncertainty, and vagueness, 3) terms created in order to obtain a complete partition of a given domain, and 4) terms reflecting mere fiat boundaries. We show that epistemology-loaded terms are pervasive in biomedical vocabularies, that the “classes” they name often do not comply with sound classification principles, and that they are therefore likely to cause problems in the evolution and alignment of terminologies and associated ontologies.

The paper considers the role of modality in the rational reconstruction of standpoints and arguments. The paper examines in what conditions modal markers can act as argumentative indicators and what kind of cues they provide for the reconstruction of argument. The paper critically re-examines Toulmin’s hypothesis that the meaning of the modals can be analyzed in terms of a field-invariant argumentative force and field-dependent criteria in the light of the Theory of Relative Modality developed within linguistic semantics, showing how (...) this theory can provide a more adequate model for exploiting the modals as indicators. The resulting picture confirms Toulmin’s intuition only in part: on the one hand the modals are always relational in nature and dependent on a contextual conversational background of propositions; on the other hand only epistemic-doxastic modals directly express a speech-act level inferential relation between a set of premises and a standpoint. Other modalities express relations (e.g. causal or final relations) better seen as part of the content of the argument whose argumentative relevance depends on the argumentation scheme employed. Thus non-epistemic modals function as argumentative indicators only indirectly. (shrink)

The claim that liberal democratic normative commitments are compatible with nationalism is challenged by the widely acknowledged fact that national identities invariably depend on historical myths: the nationalist defence of such publicly shared myths is in tension with liberal democratic theory’s commitment to norms of publicity, public justification, and freedom of expression. Recent liberal nationalist efforts to meet this challenge by justifying national myths on liberal democratic grounds fail to distinguish adequately between different senses of myth. Once this is done (...) (drawing on Arthur Danto’s analytical philosophy of history), it becomes apparent that historical narratives cannot be justifiably shielded from criteria of truth and significance, and that genuinely historical myths are incompatible with liberal democratic political philosophy.

Emergence is defined as a process which cannot be described by a fixed model, consisting of invariant distinctions. Hence emergence must be described by a meta‐model, representing the transition of one model to another one by means of a distinction dynamics. The dynamics of distinctions is based on the processes of variation and selection, resulting in an invariant distinction, which constrains the variety and thus defines a new system. A classification of emergence processes is proposed, based on the following (...) class='Hi'>criteria: amount of variety, internality/ externality of variation and selection, number of levels, and contingency of constraint. It is argued that traditional formal and computational models are incapable of representing the more general types of emergence, but that it is possible to generalize them on the basis of the dynamics of distinctions.

Eleanor Knox has argued that our concept of spacetime applies to whichever structure plays a certain functional role in the laws (the role of determining local inertial structure). I raise two complications for this approach. First, our spacetime concept seems to have the structure of a cluster concept, which means that Knox's inertial criteria for spacetime cannot succeed with complete generality. Second, the notion of metaphysical fundamentality may feature in the spacetime concept, in which case spacetime functionalism may be (...) uninformative in the absence of answers to fundamental metaphysical questions like the substantivalist/relationist debate.

This dissertation offers an interpretation of David Hume's political and economic theory that challenges an accepted view this theory. According to this accepted view, Hume offers no positive criteria that maybe used to criticize existing institutions. Against this view, it is argued that Hume thinks that the best society will be one that promotes three distinct human ends---ends he calls industry, knowledge, and humanity. These are, respectively, the active pursuit of intellectual or sensual gratification, the cultivation of the arts (...) and sciences, and the active pursuit of what is good for humankind overall. Hume thinks that the society that promotes these ends will be one marked by what he calls sociability and the spirit of refinement. In such a society, people interact freely and openly with one another, and learning and the arts are widely cultivated. ;The author argues that for Hume, such a society cannot be brought about directly. Instead, enlightened lawgivers must focus on creating the necessary conditions for a sociable and refined society to come about. Hume thinks that the most refined and social society will also be the most commercial. People will be free to produce goods not only for their own consumption but also to trade with others. Further, for commerce to develop freely, a society must first have a government that Hume calls civilized. That is, it must be governed by a system of laws that apply equal to all citizens, that protect both persons and their property, and that govern the behavior of legislators themselves. ;Hume thinks that social progress will invariably be incremental, heavily dependent on the history and customs of the society involved. Reformers must keep always in mind that, except under the least tolerable of regimes, it is worse to try to improve society and fail than not to try at all. (shrink)

Those who have views about the relation between aesthetic and ethical value often also have views about the nature of art criticism. Yet no one has paid much attention to the compatibility of views in one debate with views in the other. This is worrying in light of a tension between two popular kinds of view: namely, between critical pluralism and any view in the art and ethics debate that presupposes an invariant relation between aesthetic value and ethical value. Specifically, (...) the tension with invariance arises insofar as critical pluralism accommodates the aesthetic value of interpretive richness, including the aesthetic value of ethically conflicted interpretive richness. Given this tension, a shift of focus is needed in the art and ethics debate; from specifying the criteria for the aesthetic relevance of a work's ethical qualities to defending the fundamental nature of the aesthetic-ethical value relation.

It is argued that the acceptance of knowledge in a community depends on several, approximately independent selection "criteria". The objective criteria are distinctiveness, invariance and controllability, the subjective ones are individual utility, coherence, simplicity and novelty, and the intersubjective ones are publicity, expressivity, formality, collective utility, conformity and authority. Science demarcates itself from other forms of knowledge by explicitly controlling for the objective criteria.

Starting with Popper, social theorists across the board have acknowledged that traditions serve socially valuable functions. However, while traditions are usually understood as ‘living’ entities that come in overlapping varieties and evolve over time, the socially valuable functions attributed to tradition tend to presuppose invariability in ways of thinking and acting. Addressing this tension, this article provides a detailed analysis of the concept of tradition, and directs special attention to conceivable criteria for the authentic continuation of a tradition. It (...) is argued that the ways of thinking and acting that constitute the material of a tradition must – among faithful members of that tradition – stand in a relation of equivalence – not identity or similarity. The implications of this account concern our ability to decide (normatively) conflicts over authenticity among rival tradition branches as well as the role that traditions play in policy-making.

We introduce a realist, unextravagant interpretation of quantum theory that builds on the existing physical structure of the theory and allows experiments to have definite outcomes but leaves the theory’s basic dynamical content essentially intact. Much as classical systems have specific states that evolve along definite trajectories through configuration spaces, the traditional formulation of quantum theory permits assuming that closed quantum systems have specific states that evolve unitarily along definite trajectories through Hilbert spaces, and our interpretation extends this intuitive picture (...) of states and Hilbert-space trajectories to the more realistic case of open quantum systems despite the generic development of entanglement. We provide independent justification for the partial-trace operation for density matrices, reformulate wave-function collapse in terms of an underlying interpolating dynamics, derive the Born rule from deeper principles, resolve several open questions regarding ontological stability and dynamics, address a number of familiar no-go theorems, and argue that our interpretation is ultimately compatible with Lorentz invariance. Along the way, we also investigate a number of unexplored features of quantum theory, including an interesting geometrical structure—which we call subsystem space—that we believe merits further study. We conclude with a summary, a list of criteria for future work on quantum foundations, and further research directions. We include an appendix that briefly reviews the traditional Copenhagen interpretation and the measurement problem of quantum theory, as well as the instrumentalist approach and a collection of foundational theorems not otherwise discussed in the main text.

Michel Ghins and I are both empiricists, and agree significantly in our critique of “traditional” empiricist epistemology. We differ however in some respects in our interpretation of the scientific enterprise. Ghins argues for a moderate scientific realism which includes the view that acceptance of a scientific theory will bring with it belief in the existence of all those entities, among the entities the theory postulates, that satisfy certain criteria. For Ghins these criteria derive from the criteria for (...) legitimate affirmation of existence for any entities, the directly observable ones not being privileged in that respect. They are roughly that the putatively existing entity should according to the accepted theory manifest itself in our experience, and display a certain permanence and invariance. My disagreement on this topic derives from a larger difference concerning the relation between experience, existence, and theory. (shrink)

In this paper I argue in favour of a moderate and selective version of scientific realism with respect to the existence of some physical theoretical objects and the truth of some statements about them. The analysis of common sense or ordinary experience reveals that existence and truth assertions concerning familiar objects are warranted if they satisfy what we call the criteria of presence and invariance. Ordinary objects exemplify a form or a structure determined by constant and changing features (...) with respect to the variation of the conditions of observation and a content given in sensory presence. It is claimed that some theoretical physical objects that possess a structure or a form determined by invariant and variable characteristics relatively to a specified group of transformations and a content provided by observations on which the measurement of those characteristics is grounded can also be justifiably asserted to exist. We further show that this defence of scientific realism in physics doesn't fall prey to the objections that have been raised against the usual vindication of scientific realism based on the no-miracle argument. Some standard objections to scientific realism, such as the underdetermination of theories by observations and the pessimistic meta-induction, are examined and shown to be unconvincing. (shrink)

The purpose of the present study was to profile high school students’ achievement as a function of their demographic characteristics, parent attributes, and school behaviors. Students were nested within schools in the Saudi Arabia Kingdom. Out of a large sample of 500k, participants involved 3 random samples of 2,000 students measured during the years 2016, 2017, and 2018. Randomization was conducted at the student level to ensure that all school units will be represented and at their respective frequency. Students were (...) nested within 50 high schools. We adopted the multilevel latent profile analysis protocol put forth by Schmiege et al. and Mäkikangas et al. that account for nested data and tested latent class structure invariance over time. Results pointed to the presence of a 4-profile solution based on BIC, the Bayes factor, and several information criteria put forth by Masyn. Latent profile separation was mostly guided by parents’ education and the number of student absences. Two models tested whether the proportions of level 1 profiles to level 2 units are variable and whether level 2 profiles vary as a function of level 1 profiles. Results pointed to the presence of significant variability due to schools. (shrink)

Starting with Popper, social theorists across the board have acknowledged that traditions serve socially valuable functions. However, while traditions are usually understood as ‘living’ entities that come in overlapping varieties and evolve over time, the socially valuable functions attributed to tradition tend to presuppose invariability in ways of thinking and acting. Addressing this tension, this article provides a detailed analysis of the concept of tradition, and directs special attention to conceivable criteria for the authentic continuation of a tradition. It (...) is argued that the ways of thinking and acting that constitute the material of a tradition must – among faithful members of that tradition – stand in a relation of equivalence – not identity or similarity. The implications of this account concern our ability to decide (normatively) conflicts over authenticity among rival tradition branches as well as the role that traditions play in policy-making.

On the basis of an analysis of everyday experience and practice, criteria of legitimate assertions of existence and truth are offered. A specific object, like a newspaper, can be asserted to exist if it has some invariant characteristics and is present in actual perception. A statement, like “This newspaper is black and white,” can be accepted as true if it is well-established in some empirical domain. Each of these criteria provides a sufficient condition for acceptance of existence and (...) truth, respectively, at the empirical level. Following Herman Weyl, it is argued that these criteria can be extended to the scientific theoretical level to support a selective and moderate version of scientific realism according to which entities like the electromagnetic and gravitational fields, but not crystalline spheres or some topological manifolds, can legitimately be asserted to exist.

David Hume's famous riddle of induction implies a second problem related to the question of whether the laws and principles of nature might change in the course of time. Claims have been made that modern developments in physics and astrophysics corroborate the translational invariance of the laws of physics in time. However, the appearance of a new general principle of nature, which might not be derivable from the known laws of physics, or that might actually be a non-physical one (...) (this means completely independent of physical science) supports the notion that the course of nature can change in time. Here it is argued that natural selection satisfies the criteria that identify a general principle of nature which so far, appears to be non-derivable from the known laws of physics and therefore, it is likely that it arose in the course of time, thus leaving open again the quest for a true solution to Hume's second problem.

We propose a sheaf-theoretic framework for the representation of a quantum observable structure in terms of Boolean information sieves. The algebraic representation of a quantum observable structure in the relational local terms of sheaf theory effectuates a semantic transition from the axiomatic set-theoretic context of orthocomplemented partially ordered sets, la Birkhoff and Von Neumann, to the categorical topos-theoretic context of Boolean information sieves, la Grothendieck. The representation schema is based on the existence of a categorical adjunction, which is used as (...) a theoretical platform for the development of a functorial formulation of information transfer, between quantum observables and Boolean localisation devices in typical quantum measurement situations. We also establish precise criteria of integrability and invariance of quantum information transfer by cohomological means. (shrink)
