Which abstraction principles are acceptable? A variety of criteria have been proposed, in particular irenicity, stability, conservativeness, and unboundedness. This note charts their logical relations. This answers some open questions and corrects some old answers.

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.

One of the main problems plaguing neo-logicism is the Bad Company challenge: the need for a well-motivated account of which abstraction principles provide legitimate definitions of mathematical concepts. In this article a solution to the Bad Company challenge is provided, based on the idea that definitions ought to be conservative. Although the standard formulation of conservativeness is not sufficient for acceptability, since there are conservative but pairwise incompatible abstraction principles, a stronger conservativeness condition is sufficient: that (...) the class of acceptable abstraction principles be strictly logically symmetrically class conservative . The article concludes with an examination of which classes of abstraction principles meet this criteria. (shrink)

Neo-Fregean logicism attempts to base mathematics on abstraction principles. Since not all abstraction principles are acceptable, the neo-Fregeans need an account of which ones are. One of the most promising accounts is in terms of the notion of stability; roughly, that an abstraction principle is acceptable just in case it is satisfiable in all domains of sufficiently large cardinality. We present two counterexamples to stability as a sufficient condition for acceptability and argue that (...) these counterexamples can be avoided only by major departures from the existing neo-Fregean programme.

More than thirty years ago, Amari and colleagues proposed a statistical framework for identifying structurally stable macrostates of neural networks from observations of their microstates. We compare their stochastic stability criterion with a deterministic stability criterion based on the ergodic theory of dynamical systems, recently proposed for the scheme of contextual emergence and applied to particular inter-level relations in neuroscience. Stochastic and deterministic..

This paper discusses the stability of semi-Markovian jump networked control system containing time-varying delay and actuator faults. The system dynamic is optimized while the network resource is saved by introducing an improved static event-triggered mechanism. For deriving a less conservative stability criterion, the Bessel–Legendre inequalities approach is employed to the stability analysis and plays a major role. By constructing the enhanced Lyapunov–Krasovskii functional relevant to the Legendre polynomials, a stability criterion with lower conservativeness indexed by N (...) is derived, and the conservativeness will decrease as N increases. In addition, a controller is designed. To prove the validity of this paper, numerical examples are provided at the last. (shrink)

The logical status of abstraction principles, and especially Hume’s Principle, has been long debated, but the best currently availeble tool for explicating a notion’s logical character—permutation invariance—has not received a lot of attention in this debate. This paper aims to fill this gap. After characterizing abstraction principles as particular mappings from the subsets of a domain into that domain and exploring some of their properties, the paper introduces several distinct notions of permutation invariance for such (...) class='Hi'>principles, assessing the philosophical significance of each.

Kripke’s notion of groundedness plays a central role in many responses to the semantic paradoxes. Can the notion of groundedness be brought to bear on the paradoxes that arise in connection with abstraction principles? We explore a version of grounded abstraction whereby term models are built up in a ‘grounded’ manner. The results are mixed. Our method solves a problem concerning circularity and yields a ‘grounded’ model for the predicative theory based on Frege’s Basic Law V. However, (...) the method is poorly behaved unless the background second-order logic is predicative. (shrink)

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)

We examine George Boolos's proposed abstraction principle for extensions based on the limitation-of-size conception, New V, from several perspectives. Crispin Wright once suggested that New V could serve as part of a neo-logicist development of real analysis. We show that it fails both of the conservativeness criteria for abstraction principles that Wright proposes. Thus, we support Boolos against Wright. We also show that, when combined with the axioms for Boolos's iterative notion of set, New V yields (...) a system equivalent to full Zermelo-Fraenkel set theory with a principle of global choice. This advances Boolos's longstanding interest in the foundations of set theory. (shrink)

Neo-Fregeans argue that substantial mathematics can be derived from a priori abstraction principles, Hume's Principle connecting numerical identities with one:one correspondences being a prominent example. The embarrassment of riches objection is that there is a plurality of consistent but pairwise inconsistent abstraction principles, thus not all consistent abstractions can be true. This paper considers and criticizes various further criteria on acceptable abstractions proposed by Wright settling on another one—stability—as the best bet for neo-Fregeans. However, (...) an analogue of the embarrassment of riches objection resurfaces in the metatheory and I conclude by arguing that the neo-Fregean program, at least insofar as it includes a platonistic ontology, is fatally wounded by it.

Lists of species underpin many fields of human endeavour, but there are currently no universally accepted principles for deciding which biological species should be accepted when there are alternative taxonomic treatments (and, by extension, which scientific names should be applied to those species). As improvements in information technology make it easier to communicate, access, and aggregate biodiversity information, there is a need for a framework that helps taxonomists and the users of taxonomy decide which taxa and names should be (...) used by society whilst continuing to encourage taxonomic research that leads to new species discoveries, new knowledge of species relationships, and the refinement of existing species concepts. Here, we present 10 principles that can underpin such a governance framework, namely (i) the species list must be based on science and free from nontaxonomic considerations and interference, (ii) governance of the species list must aim for community support and use, (iii) all decisions about list composition must be transparent, (iv) the governance of validated lists of species is separate from the governance of the names of taxa, (v) governance of lists of accepted species must not constrain academic freedom, (vi) the set of criteria considered sufficient to recognise species boundaries may appropriately vary between different taxonomic groups but should be consistent when possible, (vii) a global list must balance conflicting needs for currency and stability by having archived versions, (viii) contributors need appropriate recognition, (ix) list content should be traceable, and (x) a global listing process needs both to encompass global diversity and to accommodate local knowledge of that diversity. We conclude by outlining issues that must be resolved if such a system of taxonomic list governance and a unified list of accepted scientific names generated are to be universally adopted. (shrink)

This article provides a methodology for the interpretation of AI ethics principles to specify ethical criteria for the development and deployment of AI systems in high-risk domains. The methodology consists of a three-step process deployed by an independent, multi-stakeholder ethics board to: (1) identify the appropriate level of abstraction for modelling the AI lifecycle; (2) interpret prescribed principles to extract specific requirements to be met at each step of the AI lifecycle; and (3) define the (...) class='Hi'>criteria to inform purpose- and context-specific balancing of the principles. The methodology presented in this article is designed to be agile, adaptable, and replicable, and when used as part of a pro-ethical institutional culture, will help to foster the ethical design, development, and deployment of AI systems. The application of the methodology is illustrated through reference to the UK Ministry of Defence AI ethics principles. (shrink)

Research that has been sponsored by pharmaceutical, medical device and biotechnology companies is often presented at scientific and medical conferences. However, practices vary between organizations and it can be difficult to follow both individual conference requirements and good publication practice guidelines. Until now, no specific guidelines or recommendations have been available to describe best practice for conference presentations.This document was developed by a working group of publication professionals and uploaded to PeerJ Preprints for consultation prior to publication; an additional 67 (...) medical societies, medical conference sites and conference companies were also asked to comment. The resulting recommendations aim to complement current good publication practice and authorship guidelines, outline the general principles of best practice for conference presentations and provide recommendations around authorship, contributorship, financial transparency, prior publication and copyright, to conference organizers, authors and industry professionals.While the authors of this document recognize that individual conference guidelines should be respected, they urge organizers to consider authorship criteria and data transparency when designing submission sites and setting parameters around word/character count and content for abstracts. It is also important to recognize that conference presentations have different limitations to full journal publications, for example, in the case of limited audiences that necessitate refocused abstracts, or where lead authors do not speak the local language, and these have been acknowledged accordingly. The authors also recognize the need for further clarity regarding copyright of previously published abstracts and have made recommendations to assist with best practice.By following Good Practice for Conference Abstracts and Presentations: GPCAP recommendations, industry professionals, authors and conference organizers will improve consistency, transparency and integrity of publications submitted to conferences worldwide.

Concepts of stability and symmetry in irreversible thermodynamics are developed through the analysis of system energy flows. The excess power function, derived from a local energy conservation equation, is shown to yield necessary and sufficient stability criteria for linear and nonlinear irreversible processes. In the absence of symmetry-destroying external forces, the linear range may be characterized by a set of phenomenological coefficient symmetries relating coupled forces and displacements, velocities, and accelerations, whereas rotational phenomena in nonlinear processes may (...) be characterized by skew-symmetric components of the phenomenological coefficients. A physical interpretation of the nature of the skew-symmetric parts is given and the variational principle of minimum dissipation of energy is related to a stability criterion. (shrink)

Grossberg and VanDieren have started a program to develop a stability theory for tame classes. We name some variants of tameness and prove the following. Let K be an AEC with Löwenheim-Skolem number ≤κ. Assume that K satisfies the amalgamation property and is κ-weakly tame and Galois-stable in κ. Then K is Galois-stable in κ⁺ⁿ for all n<ω. With one further hypothesis we get a very strong conclusion in the countable case. Let K be an AEC satisfying the amalgamation (...) property and with Löwenheim-Skolem number ℵ₀ that is ω-local and ℵ₀-tame. If K is ℵ₀-Galois-stable then K is Galois-stable in all cardinalities.

Objects which philosophers have traditionally categorized as abstract are standardly referred to by complex noun phrases of certain canonical forms, such as ‘the set of Fs’, ‘the number of Fs’, ‘the proposition that P’, and ‘the property of being F’. It is no accident that such noun phrases are well-suited to appear in ‘Fregean’ identity-criteria, or ‘abstraction’ principles, for which Frege’s criterion of identity for cardinal numbers provides the paradigm. Notoriously, such principlesare apt to create paradoxes, and (...) the most intuitively plausible ‘Fregean’ identity-criterion for properties is afflicted by this problem. In this case, it may be possible to overcome the difficulty by modifying the criterion in a way which requires an independent account of the existence-conditions of properties, but it appears that such a strategy demands acceptance of the doctrine of immanent realism—the view that a property exists only if it is exemplified by some object.

In lieu of an abstract, here is a brief excerpt of the content:Diagnostic Criteria, Psychological Tests, and Ratings Scales: Extending the HistoryPeter Zachar, PhD (bio)Le moigne narrates a history of the development of psychiatric ratings scales as hybrids between psychological tests and diagnostic categories. In his telling, psychological tests seek to quantify population-based traits on which every person has a position and which tend to be conceptualized as being stable. Personality traits are often conceptualized as dispositions. Diagnostic categories represent (...) not trait-like properties of populations but episodic states consisting of clusters of symptoms experienced by individuals with disorders. Ratings, scales, he notes, are hybrids between the two. They are used to quantify psychiatric symptom clusters so that change over time can be measured. Le Moigne argues that these distinctions were initially suggested during the development of measures that could assess outcomes in psychopharmacological treatment studies.With respect to depression, Le Moigne writes that in the 1970s and 1980s something akin to depressive personality was reconceptualized as a temperament. A key move, somewhat reflective of Kraepelin’s notion of a depressive temperament, was to view a dysthymic temperament as both a predisposing factor and an attenuated form of depression. Thus, an episodic state commandeered the predisposing–dispositional role that was assigned to stable personality traits.This conceptual shift allowed test-like ratings scales to be seen as useful for quantifying not just stable traits, but salient features of episodic states that are potentially subject to change in response to interventions. To put it another way, in the development of a psychological test, one goal is to have high test-retest reliability (i.e., stability of measurement). With rating scales used to measure change, one wants the scores to not be as stable; ideally the scores on the later assessments will be lower. According to Le Moigne, when dysthymia was subsequently placed on axis I of the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III (as a syndrome) and segregated from personality disorders which were placed on axis II, personality traits were evicted from the conceptualization of depressive disorders.One perennial feature of psychiatry and psychology is that even if an older idea is superseded [End Page 253] in the view of some thinkers, it can still attract adherents. Indeed, interest in understanding a relationship between personality and attenuated states did not fully disappear. For example, based on research in genetics, the schizophrenia spectrum concept included not only schizophrenia, but also milder conditions such that were conceptualized as personality disorders; that is, schizotypal personality disorder and paranoid personality disorder (Kety, Rosenthal, Wender, & Schulsinger, 1971).During the development of the DSM-IV, some people wanted to add depressive personality disorder to the manual (Phillips, Hirschfeld, Shea, & Gunderson, 1995). It seems to have become a territorial dispute between mood disorder specialists and personality disorder specialists The mood disorders specialists challenged the personality disorder specialists to differentiate depressive personality disorder from early onset, chronic dysthymia. They were able to do so by using criteria such as critical, blaming, and derogatory toward self. After the mood disorders work group proposed incorporating some of those criteria into a revised criteria set for dysthymia, the two sets overlapped. The result was the old criteria for dysthymia were printed in DSM-IV and criteria for depressive personality disorder and the revised criteria for dysthymia were both placed in the appendix.In the DSM-5, Axis II was eliminated and personality disorders were placed alongside all the syndromic symptom clusters at the same level. Even so, interest in attenuated presentations as personality-related lingered still. During the development of the DSM-5 there was some thought to using diagnostic spectra as a meta-structure for organizing the manual (Andrews et al., 2009). One idea was to move some personality disorders into a best fitting spectrum, akin to attenuated forms. This did occur with schizotypal personality disorder which is both in the DSM-5 chapter on schizophrenia and in the chapter on personality disorder. In the schizophrenia chapter it is positioned as the earliest emerging disorder on the spectrum. There was also some interest in grouping avoidant personality disorder with the anxiety disorders, but the evidence supporting such a change was not available.These issues may... (shrink)

Wright claims that “the epistemology of good abstraction principles should be assimilated to that of basic principles of logical inference”. In this paper I follow Wright’s recommendation, but I consider a different epistemology of logic, namely anti-exceptionalism. Anti-exceptionalism’s main contention is that logic is not a priori, and that the choice between rival logics should be based on abductive criteria such as simplicity, adequacy to the data, strength, fruitfulness, and consistency. This paper’s goal is to lay (...) down the foundations for an application of the anti-exceptionalist methodology to abstraction principles. In Sect. 1 I outline my strategy. I show that anti-exceptionalism has a bearing on the so-called Bad Company problem, and explore some versions of anti-exceptionalism about abstraction. I then consider new criteria for choosing between rival abstraction principles, and, in particular, between consistent revisions of Frege’s Basic Law V. I finally consider how the abstractionist can compare between competing criteria, and argue that anti-exceptionalists should be pluralists about abstraction. (shrink)

It is widely thought that the acceptability of an abstraction principle is a feature of the cardinalities at which it is satisfiable. This view is called into question by a recent observation by Richard Heck. We show that a fix proposed by Heck fails but we analyze the interesting idea on which it is based, namely that an acceptable abstraction has to “generate” the objects that it requires. We also correct and complete the classification of proposed criteria (...) for acceptable abstraction. (shrink)

The paper takes thePrincipal Principle to be a norm demanding that subjective degrees of belief of a Bayesian agent be equal to the objective probabilities once the agent has conditionalized his subjective degrees of beliefs on the values of the objective probabilities, where the objective probabilities can be not only chances but any other quantities determined objectively. Weak and strong consistency of the Abstract Principal Principle are defined in terms of classical probability measure spaces. It is proved that the Abstract (...) Principal Principle is weakly consistent and that it is strongly consistent in the category of probability measure spaces where the Boolean algebra representing the objective random events is finite. It is argued that it is desirable to strengthen the Abstract Principal Principle by adding a stability requirement to it. Weak and strong consistency of the resulting Stable Abstract Principal Principle are defined, and the strong consistency of the Abstract Principal Principle is interpreted as necessary for a non-omniscient Bayesian agent to be able to have rational degrees of belief in all epistemic situations. It is shown that the Stable Abstract Principal Principle is weakly consistent, but the strong consistency of the Stable Abstract Principal principle remains an open question. We conclude that we do not yet have proof that Bayesian agents can have rational degrees of belief in every epistemic situation. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Response to Elvira Panaiotidi, “The Nature of Paradigms and Paradigm Shifts in Music Education”Carlos Xavier RodriguezElvira Panaiotidi has delivered a very useful and appealing paper on the topic of how the music education community decides it is time to change the way it thinks and acts. Her primary focus is whether the concept of "paradigms" proposed by Thomas Kuhn in The Structure of Scientific Revolutions reasonably explains how change (...) occurs in music education theory and practice and, if not, whether it can be modified so that it does. Following Peter Abbs' account of paradigm shifts in arts education, she proposes that paradigm shifts occur when methods of inquiry change even if what is being analyzed does not change. More specifically, paradigm shifts involve gradual transformations such that certain principles and terminology are carried over from the previous paradigm to the new one, and change at a slower rate than the methodologies adopted to make sense of them. Such discrepancy creates the kind of communicative discord she alludes to in her introduction: the aesthetic/praxial debate. Her further analysis of Abbs' argument leads her to conclude that the paradigm shifts he describes in arts education are different in kind from those intended by Kuhn. They apparently lack conceptual modification, or "conversion experience," and seem motivated by the need for increasingly comprehensive explanations of artistic behavior and thinking.Panaiotidi's synopsis of Kuhn's original criteria for paradigms reminded me [End Page 108] that his Structure of Scientific Revolutions as my first college textbook, exerted a powerful influence on me by its power to explain how humans formulate and react to new and better ideas. Panaiotidi seems to share this feeling, and scrutinizes Kuhn's original intention to use paradigms as a way of delineating the natural sciences from the humanities. Kuhn himself cautioned that his characterization of change and progress in science is not readily applicable to the arts and, more importantly, that interpretive frameworks for understanding art are not paradigms because paradigms are not theories, a distinction he echoed throughout his career. I argue that Kuhn would not consider the aesthetic and praxial approaches to music education paradigms at all; rather they are more a search for "a more inclusive theory" as Panaiotidi states. However, the ready applicability of Kuhn's criteria for paradigms to the work of music education philosophers is apparent. Their writings have been "sufficiently unprecedented to attract an enduring group of adherents away from competing modes of scientific activity." They have become associated with new methodological strategies because their writings are "sufficiently open-ended to leave all sorts of problems for the redefined group of practitioners to solve."There is, however, quite a difference in the way that science and art communities function. As Ted Gracyk writes in his book, I Wanna Be Me: Rock Music and the Politics of Identity:Where a scientific community singles out one paradigm as the foundation for further research, artistic communities do not. Once Newtonian mechanics was accepted as a scientific paradigm, no other approach to mechanics counted as a rational basis for mechanics. "Unlike art," Kuhn observes, "science destroys its past." The artworld can admire multiple paradigms, representing different periods in art history, without risking incoherence: Picasso's success did not lead museums to put their Rembrandts into storage."1Perhaps, then, the discord noted by Panaiotidi between "aestheticians" and "praxialists" arises not from a shortcoming of music education theory to provide what she calls "tenacious theoretical footing which could help settle the dispute," but from a too-literal interpretation of Kuhn's original criterion that applies to the natural sciences: new paradigms must necessarily refute those that have preceded them. Indeed, the music education research community has grappled with this very issue in its polarized views of acceptable research practice, which is perhaps more fundamentally a misunderstanding regarding the nature of the sciences versus the nature of the humanities. We in arts education have long admired scientific inquiry for its relative stability, what Kuhn calls a "normal" versus "revolutionary" mode of activity. However, as Panaiotidi explains, "Normal science [End Page 109] is characterized by a broad consensus of the specialists and is not by its nature... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.4 (2003) 564-565 [Access article in PDF] Samuel J. Kerstein. Kant's Search for the Supreme Principle of Morality. New York: Cambridge University Press, 2002. Pp. xiv + 226. Cloth, $60.00. Summed up in a sentence, this book is both a critical examination of Kant's claim to have derived a supreme moral principle and a limited defense of Kant's project that appears to depart (...) significantly from Kant's own approach. Methodologically, a large portion of this book is devoted to analyzing various key concepts and claims about the nature of the categorical imperative in the Groundwork of the Metaphysics of Morals and the Critique of Practical Reason and testing them against "everyday" moral intuitions via numerous examples and counterexamples.Kerstein begins by distinguishing between the tasks of deduction and derivation of a supreme moral principle, whereby a deduction is understood as an argument for the existence of a supreme moral principle, and a derivation simply assumes this conditionally and goes on to argue that a particular principle and no other can claim the title. Kerstein waives the discussion of whether Kant succeeds in giving a deduction and hence satisfactorily refutes moral skepticism. His focus in the book is on the derivation proposed primarily in Groundwork I and II that if there is a supreme moral principle, then it must be that law expressed in his formulations of the Categorical Imperative (hereafter "CI"). Kerstein addresses Bruce Aune's "traditional" reading of Kant's derivation, wherein the argument utterly fails because Kant allegedly infers a relatively substantive command ("Act only on that maxim which you can at the same time will to be universal law") from a purely formal, higher order, and hence relatively empty one ("Conform your actions to universal law"). He then devotes a chapter each to two recent, influential defenses of Kant's derivation that seek his argument outside the Groundwork. Kerstein addresses Henry Allison's attempt to rescue the derivation via an account of agency rooted in Kant's notion of transcendental freedom, elaborated in the second Critique. Kerstein rejects Allison's reconstruction on the grounds that it remains too abstract to generate the degree of specificity arrived at in Kant's Groundwork universalization formulation. Chapter Three examines Christine Korsgaard's alternative reconstruction of Kant's argument that focuses on the formulation of humanity ("Act so as to treat humanity, whether in your own person or that of any other, always as an end and never as a means only"). He rejects her interpretation because, again, the move from the abstract command to conform to universal law to the substantive formulation about humanity as a universally recognizable unconditional good fails. From the former, more abstract claim, he argues, it does not follow that there is a universally recognizable unconditional good, let alone that this good is humanity in itself (and not, say, utility [happiness], or even some intrinsic value unrelated to humanity, both of which Kant rejects as candidates for the unconditionally good).In his own reconstruction, Kerstein dissolves the criticism of the traditional reading of Kant's Groundwork derivation of the formula of universal law by simply denying that Kant [End Page 564] argues directly from the more generic principle to the specific versions of the CI (91ff). Instead he suggests that Kant's argument is less direct, made by way of laying out a set of criteria that any supreme principle must meet, and showing how the CI meets them while no other candidates can. In the second half of the book he takes a painstaking and critical look at a total of eight criteria, each of which Kant holds to be necessary and together are jointly sufficient for establishing the CI as "the supreme norm for the evaluation of the moral permissability and requiredness of an action, but not of its moral value" (165). This statement includes Kerstein's most controversial and interesting reconstructive claim, namely his denial that moral worth attaches only to actions done in accordance with duty as determined by the test...

Some tools introduced by Linnebo to show that mathematical entities are thin objects can also be applied to non-mathematical entities, which have been thought to be thin as well for a variety of reasons. In this paper, I discuss some difficulties and opportunities concerning the application of abstraction and interpretational modalities to mereological sums. In particular, I show that on one hand some prima facie attractive candidates for the role of an explanatory plural abstraction principle for mereological sums (...) (in terms of pluralities of summed entities) are not really explanatory; on the other hand, singular abstraction principles (in terms of single summed entities) are materially inadequate. Nonetheless, explanatory criteria of identity and conditions of existence for mereological sums are provided by classical extensional mereology independent of abstraction principles. Thus, given classical extensional mereology, the reasons why, according to Linnebo, mathematical abstracted entities are thin also hold for mereological sums. Finally, I contend that interpretational modalities can be used to characterise the process by which a subject adds sums of previously admitted entities to the domain of quantification. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Why Political Liberalism? On John Rawls’s Political Turn by Paul WeithmanMatthew ArboWhy Political Liberalism? On John Rawls’s Political Turn Paul Weithman New York: Oxford University Press, 2010. 379 pp. $65.00In Why Political Liberalism? Paul Weithman takes a bifocal look at political liberalism in the Rawlsian tradition. First he interrogates the rationale for John Rawls’s “political turn” from A Theory of Justice to Political Liberalism. Second, he explores the (...) viability of political liberalism in contemporary Western societies. The soundness of the former—the logic of Rawls’s argument, that is—validates the workability of the latter. Weithman argues that the monumental turn in Rawls’s thought is based first on his dissatisfaction with how Theory of [End Page 203] Justice treated the principle of stability, failing as it did to show that “members of a [well-ordered society] would all judge it good to preserve their ‘firm good will’” (369). Liberalism emerged as a potential answer to the question of stability by further elaborating the criteria for fairness and reasonableness in a civil society composed of citizens desirous of justice and who maintain for themselves a “sense” of justice. Weithman affirms Rawls’s explanation of how the virtue of justice is displayed in fairness and reasonableness. Just how monumental this shift turns out to be, however, depends a great deal on how compelling one finds “justice as fairness” to be.In recent decades, reasonable doubts have been expressed over the viability of Rawls’s liberal dictum: whether liberty and equality are mutually reinforcing or parasitic, or whether fairness is too morally opaque to shoot for as a political ideal. Weithman seems to believe the principle sound; it is, after all, merely a descriptive explanation of how justice is upheld politically, not a prescriptive project. Rawls concerned himself with the stability and endurance of political liberalism and with how to achieve fair and rational equilibrium. Why Weithman believes the project of Rawlsian liberalism to be fruitful, or at least philosophically successful, is due at least in part to its repeated appeal to reasonableness—that is, the rational promotion of equal liberty for all citizens. Political liberalism, as a theory, affirms and encourages all that the West values in civil society: We must desire and actively support justice for it to be preserved.This book is intended primarily for Rawls scholars. Weithman assumes his reader to have “fairly sophisticated” acquaintance with Rawls’s major theories and texts, and thus also assumes proficiency in symbolic logic and analytic methods. Weithman furnishes a way around this demand for analytic aptitude from all readers, however, by inviting those “uninterested in textual exegesis” and “content with a general understanding” of why Rawls made his turn to “read selectively” from chapters 3 through 9 (15). Be that as it may, all eleven chapters of this text are dense, rigorous, and tightly argued—standard industry practice in contemporary analytic philosophy. If one can also forebear the methodological vices of analytic philosophy, its propensity for tedious detail and narrowness, then one will eventually enjoy unexpected clarity on the subject under consideration. It will be of value to scholars with interests in the development of Rawlsian thought, the conditions for the possibility of political liberalism, and theories of justice Rawls’s account of liberalism seeks to elucidate.I doubt one unconvinced by Rawls’s political vision will undergo intellectual conversion upon reading Weithman’s Why Political Liberalism?, but that is not the point. His aim is to defend Rawls’s political turn and the project of political liberalism broadly construed. Defense of the former is done rather successfully; defense of the latter may require more voices than Weithman’s.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.4 (2003) 562-564 [Access article in PDF] Louis E. Loeb. Stability and Justification in Hume's Treatise. New York: Oxford University Press, 2002. Pp. xvi + 280. Cloth, $42.50. As is well known, in the last year of his life, Hume repudiated his Treatise of Human Nature in an Advertisement that he had placed at the front of the volume of his writings (...) containing his mature philosophical works. He asked that only the two Enquiries and other later philosophical writings be regarded as the source of "his philosophical sentiments and principles." But not leaving it at that, he admitted that there were "negligences in his... reasoning" and in his manner of expressing himself in the Treatise. More than twenty years earlier, Hume had admitted that publishing the Treatise in its imperfect state in his youth constituted "a very great Mistake in Conduct." But he did not have sufficient foresight to see that the admission he made in his old age constituted at least as bad an indiscretion of the same kind. Acknowledging mistakes in reasoning and in expression for a philosopher [End Page 562] is like waving a red flag in front of a bull. Two bulls in fact: the philosopher and the "reconstructive" historian of philosophy. The former is given ample work in correcting the older philosopher's mistakes; the latter in devising an interpretation of a text that apparently leaves itself open to many. Hence the immense popularity that Hume's Treatise of Human Nature has enjoyed in the two and a half centuries since he asked that it be disregarded. Who cares about "his philosophical sentiments and principles" anyway?Louis Loeb's study of epistemology in Hume's Treatise is both an exercise in "reconstructive history of philosophy" and a philosophical emendation of Hume's (reconstructed) "philosophical system." The first task is pursued in the first five chapters of the book; the second in the last two. "Reconstructive history" as practiced by Loeb does not try to provide "a balanced commentary" but rather "an illuminating and fruitful interpretive perspective" (viii) on what a philosopher has written. Loeb's perspective on Hume's epistemology is derived from details of Hume's psychology of the imagination developed mainly in sections 9-13 of part 3 of book 1, details which Hume himself considered "unnecessary" to the exposition of his mature epistemology in the first Enquiry. Loeb's philosophical emendations derive from his claim that Hume made certain mistakes which led him to despair of the success of his project and settle for sceptical conclusions in part 4. In the last two chapters of the book Loeb seeks to save Hume from his own sceptical conclusions.Loeb regards his account as a development and correction of the kind of naturalistic interpretation of Hume's epistemology that was originally developed by Norman Kemp Smith (21). A naturalistic theory of justification, according to Loeb, is one that grounds beliefs that one already considers to be justified in the psychological mechanisms that generate them. Whereas Kemp Smith argued that justification depends on the "irresistibility" or "inevitability" of the beliefs, Loeb holds that justification depends upon what he calls the "stability" of the belief generating mechanisms. A belief forming mechanism is stable just in case it produces a consistent set of beliefs that will stand up even under "reflection." For example, in part 3 of book 1 (81, 159, 238), Hume presents beliefs based on cause and effect as stable in this sense, and contrasts them with "unphilosophical" belief forming mechanisms such as indoctrination (education). Unlike the former, the latter mechanism generates beliefs that "are frequently contrary... to themselves in different times and places and is never on that account recognized by philosophers" (Treatise117). Furthermore, we have a positive motivation to accept stable mechanisms in that they produce ease or relief from psychological tension. Loeb links this goal both with the ancient Pyrrhonian quest for ataraxia (6-9) and with Hume's moral theory, where he seeks a general point of view as a relief from... (shrink)

Lynch et al. (Biol Philos 34:62, 2019) employ stability, specificity, and proportionality as criteria for evaluating microbiome causal explanations. Although these causal characteristics signify relevant differences between causal roles, I suggest that they should not be used as general criteria for strong or good causal explanations.

ABSTRACT:The purpose of this paper is to formulate and defend a set of moral principles applicable to management. Our motivation is twofold: 1) to increase the coherence and utility of Integrative Social Contracts Theory (ISCT); and 2) to initiate an alternative stream of business ethics research. To those ends, we specify what counts as adequate guidance in navigating the ethical terrain of business. In doing so, a key element of ISCT, Substantive Hypernorms, is found to be flawed beyond repair. (...) So we propose and defend a remedy:prima faciemoral principles. After delineating the appropriate criteria and format for such principles, we formulate, explain, and defend five of them. We conclude with a brief comment on future research possibilities. (shrink)

In this paper, I present a class of ‘structural’ abstraction principles, and describe how they are suggested by some features of Cantor's and Dedekind's approach to abstraction. Structural abstraction is a promising source of mathematically tractable new axioms for the neo-logicist. I illustrate this by showing, first, how a theorem of Shelah gives a sufficient condition for consistency in the structural setting, solving what neo-logicists call the ‘bad company’ problem for structural abstraction. Second, I show (...) how, in the structural setting, we can measure the logical strength of abstraction principles using categories of interpretations between theories. (shrink)

Contemporary brain reading technologies promise to provide the possibility to decode and interpret mental states and processes. Brain reading could have numerous societally relevant implications. In particular, the private character of mind might be affected, generating ethical and legal concerns. This paper aims at equipping ethicists and policy makers with conceptual tools to support an evaluation of the potential applicability and the implications of current and near future brain reading technology. We start with clarifying the concepts of mind reading and (...) brain reading, and the different kinds of mental states that could in principle be read. Subsequently, we devise an evaluative framework that is composed of five criteria-accuracy, reliability, informativity, concealability and enforceability-aimed at enabling a clearer estimation of the degree to which brain reading might be realistically deployed in contexts where mental privacy could be at stake. While accuracy and reliability capture how well a certain method can access mental content, informativity indicates the relevance the obtainable data have for practical purposes. Concealability and enforceability are particularly important for the evaluation of concerns about potential violations of mental privacy and civil rights. The former concerns the degree with which a brain reading method can be concealed from an individual’s perception or awareness. The latter regards the extent to which a method can be used against somebody’s will. With the help of these criteria, stakeholders can orient themselves in the rapidly developing field of brain reading. (shrink)

This article improves two existing theorems of interest to neologicist philosophers of mathematics. The first is a classification theorem due to Fine for equivalence relations between concepts definable in a well-behaved second-order logic. The improved theorem states that if an equivalence relation E is defined without nonlogical vocabulary, then the bicardinal slice of any equivalence class—those equinumerous elements of the equivalence class with equinumerous complements—can have one of only three profiles. The improvements to Fine’s theorem allow for an analysis of (...) the well-behaved models had by an abstraction principle, and this in turn leads to an improvement of Walsh and Ebels-Duggan’s relative categoricity theorem.

Objects appear to fall into different sorts, each with their own criteria for identity. This raises the question of whether sorts overlap. Abstractionists about numbers—those who think natural numbers are objects characterized by abstraction principles—face an acute version of this problem. Many abstraction principles appear to characterize the natural numbers. If each abstraction principle determines its own sort, then there is no single subject-matter of arithmetic—there are too many numbers. That is, unless objects can (...) belong to more than one sort. But if there are multi-sorted objects, there should be cross-sortal identity principles for identifying objects across sorts. The going cross-sortal identity principle, ECIA2 of Cook and Ebert (2005), solves the problem of too many numbers. But, I argue, it does so at a high cost. I therefore propose a novel cross-sortal identity principle, based on embeddings of the induced models of abstracts developed by Walsh (2012). The new criterion matches ECIA2’s success, but offers interestingly different answers to the more controversial identifications made by ECIA2. (shrink)

We introduce a family of rank functions and related notions of total transcendence for Galois types in abstract elementary classes. We focus, in particular, on abstract elementary classes satisfying the condition known as tameness, where the connections between stability and total transcendence are most evident. As a byproduct, we obtain a partial upward stability transfer result for tame abstract elementary classes stable in a cardinal $\lambda$ satisfying $\lambda^{\aleph_{0}}\gt \lambda$, a substantial generalization of a result of Baldwin, Kueker, and (...) VanDieren. (shrink)

Health-promoting nudges have been put into practice by different agents, in different contexts and with different aims. This article formulates a set of criteria that enables a thorough ethical evaluation of such nudges. As such, it bridges the gap between the abstract, theoretical debates among academics and the actual behavioral interventions being implemented in practice. The criteria are derived from arguments against nudges, which allegedly disrespect nudgees, as these would impose values on nudgees and/or violate their rationality and (...) autonomy. Instead of interpreting these objections as knock-down arguments, I take them as expressing legitimate worries that can often be addressed. I analyze six prototypical nudge cases, such as Google’s rearrangement of fridges and the use of defaults in organ donation registration. I show how the ethical criteria listed are satisfied by most—but not all—nudges in most—but not all—circumstances. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.4 (2003) 564-565 [Access article in PDF] Samuel J. Kerstein. Kant's Search for the Supreme Principle of Morality. New York: Cambridge University Press, 2002. Pp. xiv + 226. Cloth, $60.00. Summed up in a sentence, this book is both a critical examination of Kant's claim to have derived a supreme moral principle and a limited defense of Kant's project that appears to depart (...) significantly from Kant's own approach. Methodologically, a large portion of this book is devoted to analyzing various key concepts and claims about the nature of the categorical imperative in the Groundwork of the Metaphysics of Morals and the Critique of Practical Reason and testing them against "everyday" moral intuitions via numerous examples and counterexamples.Kerstein begins by distinguishing between the tasks of deduction and derivation of a supreme moral principle, whereby a deduction is understood as an argument for the existence of a supreme moral principle, and a derivation simply assumes this conditionally and goes on to argue that a particular principle and no other can claim the title. Kerstein waives the discussion of whether Kant succeeds in giving a deduction and hence satisfactorily refutes moral skepticism. His focus in the book is on the derivation proposed primarily in Groundwork I and II that if there is a supreme moral principle, then it must be that law expressed in his formulations of the Categorical Imperative (hereafter "CI"). Kerstein addresses Bruce Aune's "traditional" reading of Kant's derivation, wherein the argument utterly fails because Kant allegedly infers a relatively substantive command ("Act only on that maxim which you can at the same time will to be universal law") from a purely formal, higher order, and hence relatively empty one ("Conform your actions to universal law"). He then devotes a chapter each to two recent, influential defenses of Kant's derivation that seek his argument outside the Groundwork. Kerstein addresses Henry Allison's attempt to rescue the derivation via an account of agency rooted in Kant's notion of transcendental freedom, elaborated in the second Critique. Kerstein rejects Allison's reconstruction on the grounds that it remains too abstract to generate the degree of specificity arrived at in Kant's Groundwork universalization formulation. Chapter Three examines Christine Korsgaard's alternative reconstruction of Kant's argument that focuses on the formulation of humanity ("Act so as to treat humanity, whether in your own person or that of any other, always as an end and never as a means only"). He rejects her interpretation because, again, the move from the abstract command to conform to universal law to the substantive formulation about humanity as a universally recognizable unconditional good fails. From the former, more abstract claim, he argues, it does not follow that there is a universally recognizable unconditional good, let alone that this good is humanity in itself (and not, say, utility [happiness], or even some intrinsic value unrelated to humanity, both of which Kant rejects as candidates for the unconditionally good).In his own reconstruction, Kerstein dissolves the criticism of the traditional reading of Kant's Groundwork derivation of the formula of universal law by simply denying that Kant [End Page 564] argues directly from the more generic principle to the specific versions of the CI (91ff). Instead he suggests that Kant's argument is less direct, made by way of laying out a set of criteria that any supreme principle must meet, and showing how the CI meets them while no other candidates can. In the second half of the book he takes a painstaking and critical look at a total of eight criteria, each of which Kant holds to be necessary and together are jointly sufficient for establishing the CI as "the supreme norm for the evaluation of the moral permissability and requiredness of an action, but not of its moral value" (165). This statement includes Kerstein's most controversial and interesting reconstructive claim, namely his denial that moral worth attaches only to actions done in accordance with duty as determined by the test...

This paper stems from the current global worsening of the scarcity of resources for healthcare, which will deepen even more in future public emergencies. This justifies strengthening the reflection on the allocation of resources which, in addition to considering technical issues, should also involve ethical concerns. The two plans in which the allocation of resources develops—macro and micro—are then systematized, both requiring the identification of ethical criteria for the respective complex decision-making. Then, we describe how the complexity at the (...) macro level focuses on the joint consideration of the rectitude of the principles, the goodness of the ends, and the integrity—respectively the deontological, teleological, and procedural perspectives; and at the micro level, it focuses in prioritizing people, which can result in the exclusion of some, as happened with the elderly during peaks of COVID-19. The main objective of this article is to show that, in public health emergency situations, in which the daily criteria for prioritizing access to health care are not efficient, it is possible not only to ration the available means but also to rationalize them. We argue that rationing and rationalization are different concepts, entail different consequences, have different ethical foundations, and draw different guidelines for patient care. We apply them to the distribution of intensive care and vaccines to the elderly thus demonstrating the ethically legitimate domain of implementation of each of these two prioritization criteria. We conclude that rationalization respects more strictly the core ethical principles of our common morality. (shrink)

A theory of magnitudes involves criteria for their equivalence, comparison and addition. In this article we examine these aspects from an abstract viewpoint, by focusing on the so-called De Zolt’s postulate in the theory of equivalence of plane polygons (“If a polygon is divided into polygonal parts in any given way, then the union of all but one of these parts is not equivalent to the given polygon”). We formulate an abstract version of this postulate and derive it from (...) some selected principles for magnitudes. We also formulate and derive an abstract version of Euclid’s Common Notion 5 (“The whole is greater than the part”), and analyze its logical relation to the former proposition. These results prove to be relevant for the clarification of some key conceptual aspects of Hilbert’s proof of De Zolt’s postulate, in his classicalFoundations of Geometry(1899). Furthermore, our abstract treatment of this central proposition provides interesting insights for the development of a well-behaved theory ofcompatiblemagnitudes. (shrink)

Frege's views regarding analysis and synomymy have long been the subject of critical discussion. Some commentators, led by Dummett, have argued that Frege was committed to the view that each thought admits of a unique ultimate analysis. However, this interpretation is in apparent conflict with Frege's criterion of synonymy, according to which two sentence express the same thought if one cannot understand them without regarding them as having the same truth–value. In a recent article in this journal, Drai attempts to (...) reconcile Frege's criterion of synonymy with unique ultimate analysis by holding that, for Frege, if two sentences satisfy the criterion without being intensionally isomorphic, at most one of them is a privileged representation of the thought expressed. I argue that this proposal fails, because it conflicts not only with Frege's views of abstraction principles but also with slingshot arguments (including one presented by Drai herself) that accurately reflect Frege's commitment to the view that sentences alike in truth–value have the same Bedeutung. While Drai helpfully connects Frege's views of abstraction principles with such slingshot arguments, this connection cannot become fully clear until we recognise that Frege rejects unique ultimate analysis.

According to Øystein Linnebo's account of abstractionism, abstraction principles, received as Fregean criteria of identity, can be used to reduce facts about singular reference to objects such as directions and numbers to facts that do not involve such objects. In this article, first I show how the resources of Linnebo's metasemantics successfully handle Dummett's challenge against the referentiality of the singular terms formed by abstraction principles. Then, I argue that Linnebo's metasemantic commitments do not provide (...) us with tools for dispelling the threat of a version of referential indeterminacy, according to which nothing in our use of a singular term, even when it is guided by an associated criterion of identity, could determine which particular object it refers to. I end by examining the bearing of the indeterminacy challenge to Linnebo's treatment of Frege's Caesar Problem: in the absence of an argument against the indeterminacy of reference, it is unclear how numerical expressions could qualify as genuine singular terms.

A thriving literature has developed over logical and mathematical pluralism – i.e. the views that several rival logical and mathematical theories can be equally correct. These have unfortunately grown separate; instead, they both could gain a great deal by a closer interaction. Our aim is thus to present some novel forms of abstractionist mathematical pluralism which can be modeled on parallel ways of substantiating logical pluralism (also in connection with logical anti-exceptionalism). To do this, we start by discussing the Good (...) Company Problem for neo-logicists recently raised by Paolo Mancosu (2016), concerning the existence of rival abstractive definitions of cardinal number which are nonetheless equally able to reconstruct Peano Arithmetic. We survey Mancosu’s envisaged possible replies to this predicament, and suggest as a further path the adoption of some form of mathematical pluralism concerning abstraction principles. We then explore three possible ways of substantiating such pluralism—Conceptual Pluralism, Domain Pluralism, Pluralism about Criteria—showing how each of them can be related to analogous proposals in the philosophy of logic. We conclude by considering advantages, concerns, and theoretical ramifications for these varieties of mathematical pluralism. (shrink)

Interval time-varying delay is common in control process, e.g., automatic robot control system, and its stability analysis is of great significance to ensure the reliable control of industrial processes. In order to improve the conservation of the existing robust stability analysis method, this paper considers a class of linear systems with norm-bounded uncertainty and interval time-varying delay as the research object. Less conservative robust stability criterion is put forward based on augmented Lyapunov-Krasovskii functional method and reciprocally convex (...) combination. Firstly, the delay interval is partitioned into multiple equidistant subintervals, and a new Lyapunov-Krasovskii functional comprising quadruple-integral term is introduced for each subinterval. Secondly, a novel delay-dependent stability criterion in terms of linear matrix inequalities is given by less conservative Wirtinger-based integral inequality approach. Three numerical comparative examples are given to verify the superiority of the proposed approach in reducing the conservation of conclusion. For the first example about closed-loop control systems with interval time-varying delays, the proposed robust stability criterion could get MADB about 0.3 more than the best results in the previous literature; and, for two other uncertain systems with interval time-varying delays, the MADB results obtained by the proposed method are better than those in the previous literature by about 0.045 and 0.054, respectively. All the example results obtained in this paper clearly show that our approach is better than other existing methods. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:138 HUME AND WITTGENSTEIN: CRITERIA VS. SKEPTICISM As far as philosophical admonitions go, there are probably few as famous as Wittgenstein's Blue Book warning: We are up against one of the great sources of philosophical bewilderment : we try to find a substance for a substantive, (p. 1) Wittgenstein, of course, could have added: This is something we should have learned long ago from Hume. He could have (...) quoted the following passage from the Appendix to the Treatise: Philosophers begin to be reconcil'd to the principle, that we have no idea of external substance, distinct from the ideas of particular qualities. This must pave the way for a like principle with regard to the mind, that we have no notion of it, distinct from the particular perceptions. Neither causal necessitation, self, nor substances could be located by Hume no matter how hard he tried to analyse his experience of the world. For Hume, there were no experiential 'facts-of-thematter ' in virtue of which one could acknowledge, with epistemic justification, causal connectivity or necessity, the temporal extension of one's own mind, or the elusive particularity of that in which qualities are sometimes said to inhere. We know that for Hume, since he tells us, his skepticism is engendered by his inability to surrender either of the two principles, the conjunction of which he takes to be impossible. He is unable to deny that whatever is distinguishable is separable, and, as well, that there are de re connections between what is distinguishable. (T 636) What this means for Hume is that the world 'as it really is' could well be utter- 139 Iy chaotic, or, at least, structured by relations and connections which bear no resemblance to the relations and connections imposed upon our perceptions and subsequently projected onto the world. Hume, of course, is neither the disputatious sort of ersatz skeptic at whom he sneers in the opening paragraphs of An Enquiry Concerning the Principles of Morals; nor is he a fainthearted skeptic, who will, in the end, return to us everything he had only seemed to take away. We know just how unrelenting he is in his attempt to show that "the understanding never observes any real connexion among objects, and that even the union of cause and effect, when strictly examin'd, resolves itself into a customary association of ideas." (T 259-260) Although Book I of the Treatise is called "Of the Understanding," misunderstanding is not a topic that exercises Hume. Of course, it is not all that difficult to understand why this is so. 'Misunderstanding ' is, on its semantic face, inseparably concerned with language; and a concern for and about language is not something that attracts very much of Hume's explicit attention. Indeed, I am inclined to think that Hume's most important explicit comment about language is to be found in Book II, where he notes:...the sense of interest has become common to all our fellows, and gives us a confidence of the future regularity of their conduct: And 'tis only on the expectation of this, that our moderation and abstinence are founded. In like manner are languages gradually establish'd by human conventions without any promise. (T 490) 140 In Wittgensteinian terms, I think that Hume is saying, in effect, that the conventions that determine what is just with respect to property in a society are, as it were, definitive of a form of social life; that is, not agreements, contracts, or compacts — promises, as Hume refers to these — since such compacts are themselves embedded in something deeper, namely, in the human conventions that ground such compacts and contracts. Although I am going beyond what Hume says here, there is no reason to believe that we cannot identify the analogical linguistic counterparts of promises and conventions. The linguistic conventions provide the foundational matrix for the applicability of the justifying truth-making procedures. In essence, sense precedes, and determines, truth conditions. What I will argue for here is the view that it is impossible for Wittgenstein to have been a skeptic of a Humean variety; since such skepticism presupposes realism; and, whatever else Wittgenstein is, or isn't, he is not...

BackgroundThe proper and ethical inclusion of PWLHIV and their young children in research is paramount to ensure valid evidence is generated to optimize treatment and care. Little empirical data exists to inform ethical considerations deemed most critical to these populations. Our study aimed to systematically review the empiric literature regarding ethical considerations for research participation of PWLHIV and their young children.MethodsWe conducted this systematic review in partnership with a medical librarian. A search strategy was designed and performed within the following (...) electronic databases: Ovid MEDLINE, Embase and CINAHL. We screened titles and abstracts using the following inclusion criteria: (1) a study population of PWLHIV or children under 5 years of age; and (2) collection of qualitative or quantitative data regarding ethics of research participation. Excluded were reviews, commentaries, policy statements, clinical care-related ethics concerns, abstracts, case studies, or studies unrelated to HIV research. Studies were appraised for quality, data were extracted, and studies were qualitatively analyzed using a principle-based ethical framework within the Belmont Report.ResultsOf the 7470 titles identified, 538 full-text articles were reviewed for eligibility and only three articles met full criteria for inclusion within this review. While we allowed for inclusion of studies involving young children born to mothers with HIV, only articles focused on PWLHIV were identified. Within the results of these studies, four themes emerged: (1) adequacy of informed consent; (2) consideration of paternal involvement; (3) balancing risks; and (4) access to research and treatment. A strength of this review is that it included perspectives of international research investigators, community leaders, and male partners. However, only two studies collected empiric data from PWLHIV regarding their experiences participating in researchConclusionResearchers and funding agencies should be aware of these considerations and appreciate the value of and critical need for formative research to ensure clinical trials involving PWLHIV promote ethical, well-informed research participation and, ultimately, improve care outcomes. More research is needed to create a comprehensive ethical framework for researchers when conducting studies with PWLHIV. (shrink)

BackgroundThe research shows a growing trend in using an electronic platform to supplement or replace traditional paper-based informed consent processes. Instead of the traditionally written informed consent document, electronic informed consent may be used to assess the research subject’s comprehension of the information presented. By doing so, respect for persons as one of the research ethical principles can be upheld. Furthermore, these electronic methods may reduce potential airborne infection exposures, particularly during the pandemic, thereby adhering to the beneficence and (...) nonmaleficence principle. This scoping review aims to identify the ethics related criteria that have been included in electronic informed consent processes and to synthesize and map these criteria to research ethics principles, in order to identify the gaps, if any, in current electronic informed consent processes.MethodsThe search was performed based on internet search and three main databases: PubMed, SCOPUS and EBSCO. PRISMA Extension for Scoping Reviews : Checklist and Explanation guideline was used to report this work.ResultsOf 34 studies that met the inclusion criteria, 242 essential original constructs were collated, and 7 concepts were derived. Digital content showed the highest percentage of collated original constructs followed by accessibility, comprehension engagement, autonomy, confidentiality, language, and parental consent. Twenty-five new items were synthesized for eConsent criteria which may provide guidance for ethical review of research involving eConsent.ConclusionThe current study adds significant value to the corpus of knowledge in research ethics by providing ethical criteria on electronic informed consent based on evidence-based data. The new synthesized items in the criteria can be readily used as an initial guide by the IRB/rec members during a review process on electronic informed consent and useful to the future preparation of a checklist.

In this paper I proceed on the assumption that moral philosophers can and should contribute to the resolution of perplexing moral problems. The ones considered here relate to decisions concerning the distribution of scarce medical resources as between those in need of treatment. I draw on considerations of egalitarianism and concern for the maximization of the use of scarce resources in the task of satisfying basic human needs (such as for good health). I propose certain principles and offer some (...) supporting suggestions as guidelines or rules for medical decisions with a view to providing a helpful decision procedure for the various persons (doctors, community panels and so on) whose task it is to make the life-or-death decisions involved in allocating certain scarce medical resources. -/- .

A standard understanding of abstraction principles elicits two opposite readings: Intolerant Reductionism, where abstractions are seen as reducing talk of abstract objects to talk about non-problematic domains, and Robustionism, where newly introduced terms genuinely refer to abstract objects. Against this dichotomy between such “austere” and “robust” readings, Dummett suggested ways to steer intermediate paths. We explore different options for intermediate stances, by reviewing metaontological strategies and semantic ones. Based on Dummett’s and Picardi’s understanding of the Context Principle, the (...) paper acknowledges that Frege’s Grundlagen are open to several interpretations of contextual definitions, and argues that the prospects for broadly Fregean intermediate views are all but foreclosed.

In the study of reference assignment, the question of what pragmatic criteria are used to evaluate the resulting interpretation seems not yet to have been properly dealt with. This paper addresses the issue by examining factors which affect the acceptability of various cases of bridging reference. It demonstrates that even highly successful accounts of reference assignment which place major emphasis on accessibility factors, e.g. the accessibility of candidate referents and the accessibility of contextual assumptions, must nonetheless involve some pragmatic (...) criterion with which hearers can evaluate the resulting interpretation. Moreover, it argues that the pragmatic criterion used in reference assignment is not the truth-based one, which has been widely accepted, but the criterion of consistency with the principle of relevance proposed by Sperber and Wilson. Various accounts are tested against a wide range of examples on which I have conducted experimental tests with several sets of subjects. (shrink)

1. "The map of logic." Comparatively recently, Kant's words to the effect that in the two thousand years since Aristotle logic had made "not a single step forward and, all things considered, it seems to be a fully finished and completed discipline" used to be quoted widely and not unsympathetically. Today, however, there are works about logic in which the listing of logical disciplines runs into the dozens. In this regard the attempt by the American logician N. Rescher to compile (...) a diagram or "map of logic," in which the list of the branches of logic takes up several pages, is noteworthy. Also characteristic is the following statement by one of the major modern representatives of mathematical logic, S. Kleene: "Since the discovery of non-Euclidean geometries by Lobachevsky and Bolyai , it has become clear that different systems of geometries are conceptually equally possible…. Identically, there are different logics.". (shrink)
