This article explores the main similarities and differences between Derek Parfit’s notion of imprecise comparability and a related notion I have proposed of parity. I argue that the main difference between imprecise comparability and parity can be understood by reference to ‘the standard view’. The standard view claims that 1) differences between cardinally ranked items can always be measured by a scale of units of the relevant value, and 2) all rankings proceed in terms of the trichotomy of ‘better (...) than’, ‘worse than’, and ‘equally good’. Imprecise comparability, which can be understood in terms of the more familiar notions of cardinality and incommensurability, rejects only the first claim while parity rejects both claims of the standard view. -/- I then argue that insofar as those attracted to imprecise comparability assume that all rankings are trichotomous, as Parfit appears to, the view should be rejected. This is because imprecise equality is not a form of equality but is a sui generis ‘fourth’ basic way in which items can be ranked. We should, I argue, understand imprecise equality as parity, and imprecise comparability as entailing ‘tetrachotomy’ – that if two items are comparable, one must better than, worse than, equal to, or on a par with the other. Thus those attracted to the idea that cardinality can be imprecise should abandon trichotomy and accept parity and tetrachotomy instead. -/- Finally, I illustrate the difference between Parfit’s trichotomous notion of imprecise comparability and parity by examining how each notion might be employed in different solutions to the problem posed by the Repugnant Conclusion in population ethics. I suggest that parity provides the arguably more ecumenical solution to the problem. (shrink)

In this paper, we present and discuss the findings of two experiments about reference change. Cases of reference change have sometimes been invoked to challenge traditional versions of semantic externalism, but the relevant cases have never been tested empirically. The experiments we have conducted use variants of the famous Twin Earth scenario to test folk intuitions about whether natural kind terms such as ‘water’ or ‘salt’ switch reference after being constantly (mis)applied to different kinds. Our (...) results indicate that this is indeed so. We argue that this finding is evidence against Saul Kripke’s causal-historical view of reference, and at least provisional evidence in favor of the causal source view of reference as suggested by Gareth Evans and Michael Devitt.

This paper continues the defense of a version of scientific realism, Tautological Scientific Realism, that rests on the claim that, excluding some areas of fundamental physics about which doubts are entirely justified, many areas of contemporary science cannot be coherently imagined to be false other than via postulation of radically skeptical scenarios, which are not relevant to the realism debate in philosophy of science. In this paper we discuss, specifically, the threats of meaning change and reference failure associated (...) with the Kuhnian tradition, which depend on a descriptivist approach to meaning, and we argue that descriptivism is not the right account of the meaning and reference of theoretical terms. We suggest that an account along the lines of the causal-historical theory of reference provides a more faithful picture of how terms for unobservable theoretical entities and properties come to refer; we argue that this picture works particularly well for TSR. In the last section we discuss how our account raises concerns specifically for perspectival forms of scientific realism. (shrink)

This paper examines causal theories of reference with respect to how plausible an account they give of non-physical natural kind terms such as ‘gene’ as well as of the truth of the associated theoretical claims. I first show that reference fixism for ‘gene’ fails. By this, I mean the claim that the reference of ‘gene’ was stable over longer historical periods, for example, since the classical period of transmission genetics. Second, I show that the theory of partial (...) reference does not do justice to some widely held realist intuitions about classical genetics. This result is at loggerheads with the explicit goals usually associated with partial theories of reference, which is to defend a realist semantics for scientific terms. Thirdly, I show that, contrary to received wisdom and perhaps contrary to physics and chemistry, neither reference fixism nor partial reference are necessary in order to hold on to scientific realism about biology. I pinpoint the reasons for this in the nature of biological kinds, which do not even remotely resemble natural kinds (i.e., Lockean real essences) as traditionally conceived. (shrink)

For corporate memory and enterprise ontology systems to be maximally useful, they must be freed from certain barriers placed around them by traditional knowledge management paradigms. This means, above all, that they must mirror more faithfully those portions of reality which are salient to the workings of the enterprise, including the changes that occur with the passage of time. The purpose of this chapter is to demonstrate how theories based on philosophical realism can contribute to this objective. We discuss how (...) realism-based ontologies (capturing what is generic) combined with referent tracking (capturing what is specific) can play a key role in building the robust and useful corporate memories of the future. (shrink)

The goal of referent tracking is to create an ever-growing pool of data relating to the entities existing in concrete spatiotemporal reality. In the context of Electronic Healthcare Records (EHRs) the relevant concrete entities are not only particular patients but also their parts, diseases, therapies, lesions, and so forth, insofar as these are salient to diagnosis and treatment. Within a referent tracking system, all such entities are referred to directly and explicitly, something which cannot be achieved when familiar concept-based systems (...) are used in what is called “clinical coding”. In this paper we describe the components of a referent tracking system in an informal way and we outline the procedures that would have to be followed by healthcare personnel in using such a system. We argue that the referent tracking paradigm can be introduced with only minor – though nevertheless ontologically important – technical changes to existing EHR infrastructures, but that it will require a radically different mindset on the part of those involved in clinical coding and terminology development from that which has prevailed hitherto.

Partee (1973) noted anaphoric parallels between English tenses and pronouns. Since then these parallels have been analyzed in terms of type-neutral principles of discourse anaphora. Recently, Stone (1997) extended the anaphoric parallel to English modals. In this paper I extend the story to languages of other types. This evidence also shows that centering parallels are even more detailed than previously recognized. Based on this evidence, I propose a semantic representation language (Logic of Change with Centered Worlds), in which the (...) observed parallels can be formally analyzed. (shrink)

This paper is an attempt to present a Kripkean (Causal) picture of Reference where the cognitive content in fixing reference plays a vital role. It also points out that Kripke is not a pure causal theorist. By introducing Thomas Kuhn and his theory on vulnerability of the rigid designation, I have shown that there is a danger for causal theory of reference. However Kuhn’s argument fails to have an impact if a Knowledge aspect is augmented to Kripkean (...) theory of reference. This new causal theory of reference preserves the truth of the referential term in spite of the vulnerability of the rigid designation and problem of reference change. It can also adequately answer the question of theoretical terms reference failure. (shrink)

"Why are there 'transsexuals' but not 'transracials'?" "Why is there an accepted way to change sex, but not to change race?" I have repeatedly heard these questions from theorists puzzled by the phenomenon of transsexuality. Feminist thinkers, in particular, often seem taken aback that in the case of category switching the possibilities appear to be so different. Behind the question is sometimes an implicit concern: Does not the (hypothetical or real) example of individual “transracialism” seem politically troubling? And, (...) if it is, does not the case of transsexuality merit equivalent critique? Or, conversely, if one accepts transsexuals as people with legitimate demands (e.g., on medical resources or single-sex spaces), then would one not also be committed to accepting the putative transracial in analogous ways? Understanding the ontological constraints and possibilities with regard to transforming one’s identity is, I suggest, a project that should accompany ethical evaluation of those transformations. Under what circumstances is it (un)ethical to leave behind a gender or racial group with which one has once been affiliated? This question is, again, especially pressing for radical thinkers who endorse the claims that race and gender taxonomies are internally hierarchical and constituted through relations of oppression, domination, and normalization. Changing one’s identity under these circumstances will surely always be linked, however tenuously, to consideration of the larger political and cultural milieu in which such changes are advantageous or disadvantageous, complicit with oppressive norms and/or resistant to them. To illuminate these larger questions, in this paper, I first provide three examples of the analogy thesis in feminist thinking about race and sex change, each of which draws ethical conclusions about individual motivation, political strategy, or public policy, premised on the assumption that race and sex change are equivalent phenomena. None of these accounts consider the genealogy of each category as significant to contemporary possibilities. I next offer a descriptive analysis that highlights different norms at play in contemporary North American understandings: Sex–gender, I argue, is essentialized as a property of the individual’s body, while race is essentialized with reference to both the body and ancestry. This analysis, I conclude, shows politically significant disanalogies between the categories, and reveals the importance of genealogical accounts of race and sex in thinking ethically about changing ourselves.

Discussions of where the costs of climate change adaptation and mitigation should fall often focus on the 'polluter pays principle' or the 'ability to pay principle'. Simon Caney has recently defended a 'hybrid view', which includes versions of both of these principles. This article argues that Caney's view succeeds in overcoming several shortfalls of both principles, but is nevertheless subject to three important objections: first, it does not distinguish between those emissions which are hard to avoid and those which (...) are easy to avoid; second, its only partial reference to all-things-considered justice means it cannot provide a full account even of climate justice; and third, it assigns to the poor very limited duties to meet climate change costs, even where they have created those costs, which may incentivise them to increase emissions. An alternative pluralistic account which avoids these objections is presented. (shrink)

As observers, we generally have a strong impression of seeing everything in front of us at any moment. But compelling as it is, this impression is false – there are severe limits to what we can consciously experience in everyday life. Much of the evidence for this claim has come from two phenomena: change blindness (CB) and inattentional blindness (IB). -/- CB refers to the failure of an observer to visually experience changes that are easily seen once noticed. This (...) can happen even if the changes are large, constantly repeat, and the observer has been informed that they will occur. A related phenomenon is IB – the failure to visually experience an object or event when attention is directed elsewhere. For example, observers may fail to notice an unexpected object that enters their visual field, even if this object is large, appears for several seconds, and has important consequences for the selection of action. -/- Both phenomena involve a striking failure to report an object or event that is easily seen once noticed. As such, both are highly counterintuitive, not only in the subjective sense that observers have difficulty believing they could fail so badly at seeing but also in the objective sense that these findings challenge many existing ideas about how we see. But as counterintuitive as these phenomena are, progress has been made in understanding them. Indeed, doing so has allowed us to better understand the limitations of human perception in everyday life and to gain new insights into how our visual systems create the picture of the world that we experience each moment our eyes are open.

The intuition of neutrality, as discussed by John Broome, says that the addition of people does not, by itself, produce or subtract value from the world. Such intuition allows us to disregard the effects of climate change policy onto the size of populations, effectively allowing us to make policy recommendations. Broome has argued that the intuition has to go. Orsi responds by urging a normative (rather than Broome's axiological) interpretation of neutrality in terms of an exclusionary permission to disregard (...) the value of adding lives. He explores justifications and limits of such permission by referring to the prospect of human extinction. (shrink)

The biological race debate is at an impasse. Issues surrounding hereditarianism aside, there is little empirical disagreement left between race naturalists and anti-realists about biological race. The disagreement is now primarily semantic. This would seem to uniquely qualify philosophers to contribute to the biological race debate. However, philosophers of race are reluctant to focus on semantics, largely because of their worries about the ‘flight to reference’. In this paper, I show how philosophers can contribute to the debate without taking (...) the flight to reference. Drawing on the theory of reference literature and the history of meaning change in science, I develop some criteria for dealing with cases where there is uncertainty about reference. I then apply these criteria to the biological race debate. All of the criteria I develop for eliminating putative kinds are met in the case of ‘race’ as understood by twentieth century geneticist Theodosius Dobzhansky and his contemporary proponents, suggesting that we should eliminate it from our biological ontology.

Climate change can be construed as a question of collective responsibility from two different viewpoints: climate change being inherently a collective problem, or collective entities bearing responsibility for climate change. When discussing collective responsibility for climate change, “collective” can thus refer to the problem of climate change itself, or to the entity causing the harm and/or bearing responsibility for it. The first viewpoint focuses on how climate change is a harm that has been caused (...) collectively. Collective action problem refers to an aggregation of individual actions which together produce an outcome that is not intended at the level of an individual action. It cannot be solved by any one agent acting unilaterally. Instead, climate change action must be enacted and supported by numerous agents. The second way to conceptualize climate change as a question of collective responsibility focuses on the collective entities that bear responsibility for climate change. As a global problem, climate change is linked to the realm of international politics, where states, governments, and intergovernmental organizations are the main collective entities. Other important agential collectives in terms of climate responsibility are corporations, including carbon majors who have produced the bulk of emissions. Climate change has also been theorized as a structural injustice, which combines elements from both the viewpoints on what is collective about responsibility for climate change. (shrink)

Objective: Reference values have gained universal acceptance as the most powerful material that helps the decision-making-implementation process of the clinical laboratory. These values ​​may be affected by the geographical location, dietary habits, and other lifestyle changes of individuals applying to the clinical laboratory. Our study aims to determine the reference ranges for the biochemistry test panel, thyroid function tests, and insulin hormone levels, which are frequently needed by clinicians for the province of Gaziantep, with samples obtained from healthy (...) individuals. -/- Materials and Methods: In the study phase, the selection of reference individuals was carried out using the direct method a priori. For the study group, healthy individuals (224 men, 243 women) aged 18-45 were selected. Reference intervals (95% limit) were calculated according to the non-parametric method. -/- Results: When the reference intervals obtained in our study were compared with the reference intervals of the manufacturer, there were differences (> 10% lower or higher) in the upper and lower limits in urea (female and male), creatinine (male), HDL (female), AST (female and male), ALT (female), GGT (female), ALP (common), Lipase (common), CK (male), iron (male), TSH (female and male) markers. Male and female reference intervals for HDL, AST, ALT, and TSH differed significantly. Manufacturer reference ranges for these parameters were common to both sexes. -/- Conclusion: As a result, differences were determined between most of the reference intervals obtained in our study and the reference intervals we routinely use. We think the difference in the reference intervals is due to the differences in dietary habits and environmental factors. (shrink)

In its strongest, unqualified form the principle of wholistic reference is that each and every proposition refers to the whole universe of discourse as such, regardless how limited the referents of its non-logical or content terms. Even though Boole changed from a monistic fixed-universe framework in his earlier works of 1847 and 1848 to a pluralistic multiple-universe framework in his mature treatise of 1854, he never wavered in his frank avowal of the principle of wholistic reference, possibly in (...) a slightly weaker form. Indeed, he took it as an essential accompaniment to his theory of concept formation and proposition formation. Similar views are found in later logicians, and some of the most recent formulations of standard, one-sorted first-order logic seem to be in accord with a form of it, if they do not actually imply the principle itself.Em sua forma mais forte e geral, o princípio da referência universalista afirma que toda proposição refere-se ao universo completo do discurso propriamente dito, independentemente de quão limitados sejam os referentes de seus termos não-lógicos ou com conteúdo. Embora Boole mudasse de um modelo monístico de universo-fixo nos seus trabalhos iniciais de 1847 e 1848 para um modelo pluralista de universo-múltiplo no seu tratado maduro de 1854, ele nunca hesitou em sua aceitação franca do princípio da referência universalista, possivelmente em uma forma ligeiramente mais fraca. De fato, ele considerou este princípio como um acompanhamento essencial para a sua teoria de formação de conceitos e de proposições. Visões semelhantes são encontradas em lógicos posteriores, e algumas das mais recentes formulações da lógica clássica de primeira ordem parecem estar de acordo com uma forma deste, se é que elas não implicam, de fato, o próprio princípio.

In General Relativity, the terms ‘reference frame’ and ‘coordinate system’ must be distinguished. The former refers to physical systems that are dynamically coupled with the gravitational field, aside from possible approximations, while the latter refers to a set of mathematical variables that are representative artefacts. This necessary distinction is lost in pre-general relativistic physics, where we can choose as a reference frame a system of real physical objects that is not affected and cannot affect the physical system under (...) consideration. Therefore, we can make it coincide with a coordinate system without the need for approximations. We propose a a novel three-fold distinction between three types of reference frames, considered as material systems. In particular, we discern between Idealised Reference Frames, Dynamical Reference Frames and Real Reference Frames, depending on their increasing physical role in the total dynamics. Using a Bianchi I model in Minisuperspace, we give a cosmological example of the use of a gravitational Dynamical Reference Frame, namely a reference frame constructed with gravitational degrees of freedom in the standard case where the gravitational stress-energy tensor is not defined in the Einstein field equations. We also analyse the role of active and passive diffeomorphisms in changing a reference frame. (shrink)

This paper argues that indexical reference is a species of discourse reference, just like anaphora. Both varieties of discourse reference involve not only context dependence, but also context change. The act of speaking up focuses attention and thereby makes this very speech event available for discourse reference by indexicals. Mentioning something likewise focuses attention, making the mentioned entity available for subsequent discourse reference by anaphors. Empirical evidence is presented from grammatical centering in Kalaallisut and (...) "shifty indexicals" in Slave attitude reports. (shrink)

According to the propositional view of belief, a belief situation involves a believer’s standing in the relation of belief to a proposition. It is argued that the propositional view has unacceptable implications concerning the identity conditions of belief situations involving beliefs with indexical contents, especially where such beliefs are held over a period of time during which background circumstances change. After a critical discussion of Perry’s alternative to the propositional view, a version of the adverbial theory of belief, which (...) accounts satisfactorily for the identity conditions of belief situations, is advanced. This theory, which avoids the standard objections to adverbialism, is defended against the charge that it cannot provide an account of the semantics of sentences attributing the same belief to two or more believers. In the course of this defense it is argued that the standard propositional account of such sentences is insensitive to everyday language. (shrink)

In his book “Reconstruction of Scientific Change” R.M. Nugayev proposes a new model of theory change by analyzing the reasons for theory change in science. Nugayev’s theoretical concept is based on a realist’s philosophical attitude. The most important notions of Nugayev’ s conception of theory change are “theories’ cross” and “crossbred objects”, which he takes from the terminology of other Russian philosophers of science (Bransky, Podgoretzky, Smorodinsky). His investigations often refer to several famous Western philosophers. Yet (...) his study is not free of some drawbacks. Nevertheless, Nugayev’s book is worth reading and discussing within the current debate about the structure of scientific revolution and theory changes. (shrink)

The paper links higher education reforms and welfare states reforms in postcommunist Central European countries. It links current higher education debates (and reform pressures) and public sector debates (and reform pressures), stressing the importance of communist-era legacies in both areas. It refers to existing typologies of both higher education governance and welfare state regimes and concludes that the lack of the inclusion of Central Europe in any of them is a serious theoretical drawback in comparative social research. The region should (...) still, after more than two decades of transition and heavy international policy advising, be viewed as a “laboratory of social experimentation”. It is still too risky to suggest generalizations about how Central European higher education and welfare systems fit existing typologies. Consequently, the “transition” period is by no means over: it is over in terms of politics and economics but not in terms of social arrangements. Both higher education and welfare states should be viewed as “work in progress”: permanently under reform pressures, and with unclear future. (shrink)

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM) was published in 2013 containing the following changes from the previous edition: gone are the subcategories ‘Autistic Disorder,’ ‘Asperger Syndrome’ and ‘PDD-NOS,’ replaced by the single diagnosis ‘Autism Spectrum Disorder,’ and there is a new category ‘Social Communication Disorder.’ In this paper I consider what kind of reasons would justify these changes if one were (a) a realist about autism, or (b) one were a constructivist. I explore (...) various analyses of autism in the research literature that portray it as essentially either a psychological, neurological or genetic phenomenon, and discuss these by reference to the diagnostic criteria and by analogy with the way we understand race and sex categories. I conclude that no realist reasons are available to justify the changes in the diagnostic criteria, and further, that the only way the changes could be justified is if one takes the position that the DSM categories are social constructs. I conclude by exploring what implications follow from this. (shrink)

This paper develops a normative framework for both conceptualizing and assessing various institutional possibilities for democratic modes of constitutional change, with special attention to the recent ferment of constitutional experimentation. The paper’s basic methodological orientation is interdisciplinary, combining research in comparative constitutionalism, political science and normative political philosophy. In particular, it employs a form of normative reconstruction: attempting to glean out of recent institutional innovations the deep political ideals such institutions embody or attempt to realize. Starting from the assumption (...) that contemporary constitutional democracies are attempting to realize the broader ideals of deliberative democratic constitution (ideals outlined briefly in the first section), the paper proposes an evaluative framework, comprised of six criteria, for assessing various mechanisms of constitutional change. It argues that democratic forms of constitutional change embody six distinct ideals—operationalizability, structural independence, democratic co-authorship, political equality, inclusive sensitivity, and reasons-responsiveness—and that these ideals can be used to gauge the normative worth of different mechanisms for carrying out such change. The framework is developed with reference to recent constitutional developments (e.g., in Venezuela, South Africa, Columbia, Bolivia, and Iceland) highlighting distinct criteria and showing how they appear to capture the general direction of institutional innovation. The paper conjectures that the set of six criteria yield the best normative reconstruction of the crucial ideals embodied in the constitutional change mechanisms of contemporary constitutional democracies, and so, ought to be used for purposes of evaluating institutional design proposals.

A book chapter (about 9,000 words, plus references) presenting an act-consequentialist approach to the ethics of climate change. It begins with an overview of act consequentialism, including a description of the view’s principle of rightness (an act is right if and only if it maximizes the good) and a conception of the good focusing on the well-being of sentient creatures and rejecting temporal discounting. Objections to act consequentialism, and replies, are also considered. Next, the chapter briefly suggests that act (...) consequentialism could reasonably be regarded as the default moral theory of climate change, in the sense that a broadly act-consequentialist framework often seems implicit in both scholarly and casual discussions of the ethics of climate change. The remainder of the chapter explores three possible responses to the threat of climate change: having fewer children to reduce the number of people emitting greenhouse gases; taxing greenhouse-gas (GHG) emissions (commonly called a “carbon tax”) to discourage GHG-emitting behavior; and reducing poverty to lessen personal, familial, and community vulnerability to the harms of climate change.

In this paper, we assess the impact of extended reality technologies as they relate to sexual forms of harassment. We begin with a brief history of the nature of sexual harassment itself. We then offer an account of extended reality technologies focusing specifically on psychological and hardware elements most likely to comprise what has been referred to as “the metaverse”. Although different forms of virtual spaces exist (i.e., private, semi-private, and public), we focus on public social metaverse spaces. We do (...) this to better explain how the concept of sexual harassment must be adjusted to such spaces and how approaches aimed at mitigating harassment must be sensitive to the type of metaverse spaces users utilize. We then offer a typology of sexual harassment for the metaverse focusing on three distinct forms of sexual harassment: (1) invariant (2) mixed variance or modified and (3) unique or metaverse specific. Although existing normative and legal frameworks may function well with respect to the first and, possibly, second forms of harassment, we argue such frameworks will not helpfully address metaverse-specific harassment. Ultimately, the changing nature of privately owned public spaces (POPS) which metaverses are likely to represent pose distinct ethical and regulatory challenges. (shrink)

A comprehensible model is proposed aimed at an analysis of the reasons for theory change in science. According to the model the origins of scientific revolutions lie not in a clash of fundamental theories with facts, but of “old” fundamental theories with each other, leading to contradictions that can only be eliminated in a more general theory. The model is illustrated with reference to physics in the early 20th century, the three “old” theories in this case being Maxwellian (...) electrodynamics, statistical mechanics and thermodynamics. Modern example, referring to general relativity and quantum field theory fusion, is highlighted.

The paper explores the relativistic implications of the thesis of incommensurability. A semantic form of incommensurability due to semantic variation between theories is distinguished from a methodological form due to variation in methodological standards between theories. Two responses to the thesis of semantic incommensurability are dealt with: the first challenges the idea of untranslatability to which semantic incommensurability gives rise; the second holds that relations of referential continuity eliminate semantic incommensurability. It is then argued that methodological incommensurability poses little risk (...) to the rationality or objectivity of science. For rational theory choice need neither be dictated by an algorithm nor governed by a binding set of rules. The upshot of the discussion is deflationary. There is little prospect for a relativistic conception of science based on inflated claims about the incommensurability of scientific theories. (shrink)

A paradox, according to Wittgenstein, is something surprising that is taken out of its context. Thus, one way of dealing with paradoxical sentences is to imagine the missing context of use. Wittgenstein formulates what I call the paradigm paradox: ‘one sentence can never describe the paradigm in another, unless it ceases to be a paradigm.’ (PG, p.346) There are several instances of this paradox scattered throughout Wittgenstein’s writings. I argue that this paradox is structurally equivalent to Russell’s paradox. The above (...) quotation is Wittgenstein’s version of the vicious circle principle which counteracts the paradox. The prohibition Wittgenstein describes is, however, limited to a certain language-game. Finally, I argue that there is a structural analogy between a noun being employed as a self-membered set and a paradigmatic sample being included in or excluded from the set it generates. Paradoxical sentences are not prohibited forever; they can indicate a change in our praxis with a given paradigm. (shrink)

Ancient Chinese history holds a quality which has syncretized traditional thought with its cultural wealth unified of mystical and mythological figures in the background. Such that classical documents, which had begun to be written before Common Era, has directly influenced the political regime, education system and status of society in China. One of the most prominent features of these works is to propound collective knowledge about perception of cosmology, attitudes to earthiness, community standards, policy and morality. Among Five Classics works (...) of these masterpieces of Chinese philosophy, Book of Changes which stands closest to metaphysical narrative, mainly consists of the texts about prophecy. While this piece of work had been referred as a divination guide in Western Zhou Dynasty (1046-771 BC), it turned into a cosmological text that included a range of philosophical commentary during Warring States Period (475-221 BC). The mainstay of this remarkable change is the direct correlation of all the concepts and terms that characterize the worldly beyond along with the relevant text, especially yin-yang dualism, which symbolizes an extraordinary harmony in early Chinese thought. Traditional idea suggests reciprocity in which heaven, earth and man are interconnected to maintain natural order. However, the superiority attributed to human beings also brings compulsive responsibilities to idealize a compatible society. This paper aims to discuss influences of cosmological and anthropological items on human behaviors explained in prescriptive perspective. (shrink)

In traditional formal semantics the notions of reference, truth and satisfaction are basic and that of representation is derivative and dispensable. If a level of representation is included in the formal presentation of the theory, it is included as a heuristic. Semantics in the traditional sense has no bearing on any form of mental processing. When reference is understood within this framework, cognitive neuroscience cannot possibly provide any insights into the nature of reference. Traditional semantics, however, has (...) numerous shortcomings that render it inadequate as an account of natural language. Dynamic semantic theories, such as discourse representation theory (DRT), treat ever­growing, revisable mental representations as the basic semantic entities. Within this framework, there are two central notions of reference. New information may refer back to previously introduced discourse referents and discourse referents may refer to worldly entities. Because DRT treats mental representations as indispensable elements of the theory, evidence from neuroscience, particularly the recording of electroencephalograms (EEG) and its derivative event-­related potentials (ERPs), can reasonably be thought to shed light on meaning and reference within this framework. In this chapter I first review the advantages of DRT in accommodating linguistic data and then review data from neuroscience that seem to support it. Finally, I consider some methodological concerns that have been raised about the neuroscientific approach to semantics. (shrink)

As a result of the dynamic structure of society, there is a constant change in social life and researching the change is among the unit analysis of the field of sociology that takes society as a subject matter for itself. There are various ways to examine the change that has taken place in society. One of them is the implicit reference system thereby examining mindset structures. There are many factors such as economy, culture, and education which (...) constitute mentalities and one of them is religion. Religions because of their unique characters have an aspect to influence mentalities. From this point of view, the first issue in this article to be examined is the relationship between mentality-social change. Subsequently, insights will be given about mentality-religion relations, and lastly, an attempt to unearth the impact of religion-social change relations on mentalities will be made. For further clarification of all this process through an example, Sabri F. Ülgener's Zihniyet ve Din (Mentality and Religion) will be examined and Ülgener's views will be analyzed on the ground of religion-change relation. (shrink)

In this thesis, I give a metascientific account of causality in medicine. I begin with two historical cases of causal discovery. These are the discovery of the causation of Burkitt’s lymphoma by the Epstein-Barr virus, and of the various viral causes suggested for cervical cancer. These historical cases then support a philosophical discussion of causality in medicine. This begins with an introduction to the Russo- Williamson thesis (RWT), and discussion of a range of counter-arguments against it. Despite these, I argue (...) that the RWT is historically workable, given a small number of modifications. I then expand Russo and Williamson’s account. I first develop their suggestion that causal relationships in medicine require some kind of evidence of mechanism. I begin with a number of accounts of mechanisms and produce a range of consensus features of them. I then develop this consensus position by reference to the two historical case studies with an eye to their operational competence. In particular, I suggest that it is mechanistic models and their representations which we are concerned with in medicine, rather than the mechanism as it exists in the world. -/- I then employ these mechanistic models to give an account of the sorts of evidence used in formulating and evaluating causal claims. Again, I use the two human viral oncogenesis cases to give this account. I characterise and distinguish evidence of mechanism from evidence of difference-making, and relate this to mechanistic models. I then suggest the relationship between types of evidence presents us with a means of tackling the reference-class problem. This sets the scene for the final chapter. Here, I suggest the manner in which these two different classes of evidence become integrated is also reflected in the way that developing research programmes change as their associated causal claims develop.

Multicellular organisms contain numerous symbiotic microorganisms, collectively called microbiomes. Recently, microbiomic research has shown that these microorganisms are responsible for the proper functioning of many of the systems of multicellular organisms. This has inclined some scholars to argue that it is about time to reconceptualise the organism and to develop a concept that would place the greatest emphasis on the vital role of microorganisms in the life of plants and animals. We believe that, unfortunately, there is a problem with this (...) suggestion, since there is no such thing as a universal concept of the organism which could constitute a basis for all biological sciences. Rather, the opposite is true: numerous alternative definitions exist. Therefore, comprehending how microbiomics is changing our understanding of organisms may be a very complex matter. In this paper we will demonstrate that this pluralism proves that claims about a change in our understanding of organisms can be treated as both true and untrue. Mainly, we assert that the existing concepts differ substantially, and that only some of them have to be reconsidered in order to incorporate the discoveries of microbiomics, while others are already flexible enough to do so. Taking into account the plurality of conceptualisations within different branches of modern biology, we will conduct our discussion using the developmental and the cooperation–conflict concepts of the organism. Then we will explain our results by referring to the recent philosophical debate on the nature of the concept of the organism within biology. (shrink)

The climate change mitigation effort is being translated into several actions and discourses that make collateral benefits and their rationale increasingly relevant for sustainability, in such a way that they are now a constant part of the political agenda. Taking a broader and consensual perspective, co-benefits are considered here to be emerging advantages of implementing measures to lower greenhouse gases. Starting with the analysis of policy documents referring to two European urban transportation strategies, the emergent co-benefits are problematized and (...) discussed to better understand their moral aspect. Further ethical reflection is conducted after an analysis of some unintended consequences of the co-benefits rationale arising from the examples. The discussion focuses primarily on the challenges of an integrative moral justification for co-benefits and also for their role in the climate change mitigation effort. We also discuss the limitations of the current normative models that frame a co-benefits rationale, both from a moral viewpoint and in relation to the overall climate change mitigation strategy. In this article, we propose the concepts of well-being and freedom, as portrayed by the Capability Approach, as possible guiding notions for the moral and social evaluation of goodness of these emergent benefits as well as their rationale. Additionally, some preliminary conclusions are drawn regarding the potential of the presented concepts to support climate change mitigation action. Finally, we outline a scenario where the Capability Approach is the moral guideline for a co-benefits rationale and illustrates its potential in terms of enhancing climate change mitigation strategy.

People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they are implanted. (...) It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

(1) This is Part 2 of the semantic theory I call TM. In Part 1, I developed TM as a theory in the analytic philosophy of language, in lexical semantics, and in the sociology of relating occasions of statement production and comprehension to formal and informal lexicographic conclusions about statements and lexical items – roughly, as showing how synchronic semantics is a sociological derivative of diachronic, person-relative acts of linguistic behavior. I included descriptions of new cognitive psychology experimental paradigms which (...) would allow us to precisely measure the two constituents of semantics – meaning and reference – both at the level of individual speech acts and at the level of societal convergences, i.e. at both the token and type levels. -/- (2) In the Introduction, I recapitulate the arguments of Part 1. The Introduction also develops some analytic philosophical and lexical semantics themes not discussed in Part 1. -/- (3) After the Introduction, I present neural TM (nTM) as a theory of the neural mechanisms and processes which give rise to these person/occasion-relative acts of linguistic behavior. I develop nTM at three levels, the first two of which describe linguistic/semantic functions independently of their cortical locations. At the first level, I describe individual word-to-word and word-to-object connections. At the second level, I describe the corresponding structuralist networks of which they are the individual components. At this level, I introduce some key linguistic concepts of TM – its graded meaning, reference, and generalization sets, and the types of statements which express various levels of word-to-word and word-to-object relationships among lexical items which, because of the constraints they impose on the use of those lexical items in statements we produce and comprehend, are concepts. This constitutes the second structural level of nTM. -/- (4) At the third level, I associate the non-localized structures of the previous levels with cortically located neural structures and with the fasciculi that connect them. I distinguish neural areas in which primary (phonetic) and secondary (orthographic) lexicons are stored in long-term memory. I also describe the embodied concepts which co-exist in the anterior temporal lobes with the images they lexicalize. These concepts are often said to name physical objects and their features, although what they in fact name are kinds of physical objects and features. I describe how conceptual constraints and referential constraints interact to channel our intentions to say how things are into statements which are semantically well-formed, and which consequently successfully communicate information. -/- (5) Following this presentation of nTM, I examine five prominent neural semantic theories. I point out what is wrong with each of them as far as their explanations of semantics are concerned, and I also indicate how nTM can replace the “semantic cores” of those theories. -/- (6) The two basic mistakes made by neuroscience semantic theories, as I will explain, are (i) that all but one of them regard semantics as a matter of the association of words with perceptual images, and of generalizations from those associations; and (ii) that they all rely on an unspecified set of neural structures which purportedly encode the meaning of concepts in abstraction from their phonological and orthographic forms. nTM maintains, in contrast, that there are no abstract neural representations of semantic content. Neural constraints on our linguistic behavior, especially on our ascriptive and co-ascriptive use of words, express the semantic constraints on those words which make them concepts. That is the semantic content of words. -/- (7) I next consider several results from neuroscience experimental data which have been given one interpretation by one or another of the standard neurosemantic theories, but to which nTM gives a different interpretation. I include several predictions which I have found neither confirmed nor disconfirmed in the experimental neuroscience literature. -/- (8) After a concluding section in which I summarize the major changes to neurosemantic theory introduced by TM, and the analytic philosophy of language and lexical semantics contexts within which TM is situated, there follows an appendix in which I discuss neural net AI, and make some recommendations for implementing nTM in silicon.

In the poem "Reuben Bright," the speaker initially harbors a prejudiced view of Reuben, a butcher, but this prejudice transforms into awe as the speaker observes Reuben's profound change following the death of his wife. The poem delves into the theme of loss experienced by a wife and the ensuing pain endured by her husband, resulting in a profound and shattering event that triggers significant personal growth. The central focus of the poem lies in the consequential changes that Reuben (...) undergoes as a result of this tragic event. Despite the dramatic context, the reader is guided through the poem by a distanced speaker who consistently refers to Reuben in the third person. This distancing creates two layers of separation between the reader and Reuben: one between the speaker and Reuben and another between the reader and the speaker. This sense of detachment is evident in the poem's sestet, part of an Italian sonnet, and contains symbolic imagery in the form of chopped-up cedar boughs, alluding to Reuben's spiritual transformation. Additionally, the communal change in perception of Reuben is highlighted in the only two instances where the lyric "I" of the speaker appears in the poem, emphasizing the shift in the speaker's viewpoint from prejudice towards Reuben to a profound sense of awe.

Both Heraclitus and Democritus, as the philosophers of historia peri phuseôs, consider nature and human character, habit, law and soul as interrelated emphasizing the links between phusis, kinesis, ethos, logos, kresis, nomos and daimon. On the one hand, Heraclitus’s principle of change (panta rhei) and his emphasis on the element of fire and cosmic motion ultimately dominate his ethics reinforcing his ideas of change, moderation, balance and justice, on the other, Democritus’s atomist description of phusis and motion underlies (...) his principle of moderation and his ideas of health and measured life. In this series, particularly referring to the main principles of motion, moderation and justice, I attempt to describe a coherent pre-Socratic ethical perspective based on the Heraclitean and Democritean fragments. I explore the connections between their physics and ethics also borrowing from Nietzsche’s lectures and writings on the Pre-Socratics. I redefine such Heraclitean and Democritean concepts as harmony, order, perfection, health, self-control, contentment, cheerfulness, concord, sound judgment, wisdom, measure and balance and discuss them under the principles of motion (phusis), moderation (sophrosyne) and justice. In doing so, I also expose the relevance of the Heraclitean notion of logos (interpreting it as the underlying categorical principle of transition between phusis and ethos) in bringing together these ideas and principles. Finally, based on this pre-Socratic Weltanschauung, I assess the possibility of a coherent picture of humanity, its nature and conduct as extending from or fitting into or extending-from-when-fitting-into the cosmos of moving forces and atoms.

This paper proposes a reinterpretation of the Chinese worldview on equilibrium/nonequilibrium and yin-yang. Important terminologies and concepts that constitute Yijing have correlative aspects with irreversible thermodynamics and quantum reality- instability, nonlinearity, nonequilibrium and temporality. Ilya Prigogine is a Nobel laureate noted for his contribution to dissipative structures and their role in thermodynamic systems far from equilibrium, complexity and irreversibility. His expressions, as argued in this paper, resonate with the principles in Yijing. Thus, this paper attempts to re-state existing interpretations of (...) Yijing’s ideas with reference to science. Understanding Yijing’s terms and concepts must be contextualised to account for its pervasiveness of temporality and the change process. Otherwise, these cardinal concepts may be misconstrued as a hodgepodge of Eastern traditions with no relevance to modern science. This paper concentrates on the fundamental role of indeterminism in nonlinear systems on classical and quantum levels using Yijing’s conceptual framework. It concludes that the dominant ideas in Yijing and ancient Chinese philosophy resonate with the current scientific belief – the end of certainty. Instability, far-from-equilibrium, irreversibility, probability, bifurcation, and self-organisation are intrinsic properties of nature appearing at all levels, from particle, protein folding, and DNA double helix to cosmological scales. Information is the basis of all changes, and the agency of change is the human (‘ren’) with a consciousness existing in the probability space between heaven (‘tian’) and earth (‘di’). Finally, this paper outlines a modelling approach with the self-organising human in the centre between heaven and earth, representing living systems as discrete dynamical systems presented with binary choices (yin-yang). The interplay of yin and yang lines in a hexagram is thought to reflect the changing dynamics of a given situation, and the interpretation of the hexagram is based on the relationships between the yin and yang lines based on informational availability. In this way, the concepts of yin-yang and information causality are central to Yijing's understanding of change and are clarified in this paper. (shrink)

Recent studies demonstrate a moral self effect: continuity in moral values is crucial to ascriptions of identity in and over time. Since Locke, personal identity has been referred to as a ‘forensic’ concept, meaning that it plays a role in attributions of moral responsibility. If moral values are crucial to identity over time, then perceived changes in a person’s set of values may reduce responsibility for past deeds. To test this, we examined the moral self effect in parole contexts. In (...) this empirical article, we conducted two experiments, in which participants were significantly more likely to grant parole to agents who underwent a moral change as opposed to mere behavioral change. We conclude by discussing possible objections and implications of these philosophical results for the Lockean view of personal identity. -/- . (shrink)

I analyze Deleuze’s concept of temporality in terms of its ontology and axiological (political and aesthetic) aspects. For Deleuze, the concept of temporality is non-monolithic, in the senses that it is modified throughout his works — the monographs, lectures, and those works that were co-authored with Félix Guattari — and that it is developed through reference to a dizzying array of concepts, thinkers, artistic works, and social phenomena. -/- I observe that Deleuze’s concept of temporality involves a complex ontology (...) of difference, which I elaborate through reference to Deleuze’s analyses of Ancient Greek and Stoic conceptualizations of time. From Plato through to Chrysippus, temporality gradually comes to be identified as a form that comprehends the variation of particulars. Deleuze modifies the ancients’ concept of time to suggest that time obtains as a form of ceaseless ontological variation. Through reference to Deleuze’s reading of Gilbert Simondon, I further suggest that Deleuze tends to conceive of temporality as an ontogenetic force which participates in the complex process of individuation. -/- A standout feature of this dissertation involves an analysis of how Deleuze’s concept of temporality is modified in his works on cinema. In Cinema 1: The Movement-Image and Cinema 2: The Time-Image, temporality comes to be characterized as something other than the measure of the movement of existents. In his detailed analyses of Bergson — in Cinema 1: The Movement-Image, Cinema 2: The Time-Image, and Bergsonism — Deleuze suggests that time involves an actualization of aspects of a virtual past as contemporaneous with the lived present. While not an outright denial of the relation of temporal succession, Deleuze’s claim implies a diminishment of this relation’s significance in an adequate elaboration of the nature of temporality. -/- Further, I observe —through reference to Deleuze’s readings of Marx, Kierkegaard, and Spinoza — that (the explicitly temporal) change of societal forms of economic organization is non-reducible to that suggested by linear evolution. The claim is that putatively discrete modes of economic organization do not enjoy temporal displacement with respect to one another. This suggests that linear evolutionary models of societal development are inadequate. This further implies that temporality is non-reducible to the relation of temporal succession. In concrete terms, societal change is characterized as immanent temporal variation. -/- Taken together, these analyses yield the conclusion that Deleuze tends to conceive of the nature of temporality as involving the ongoing realization of multiple — non-identical, sometimes contrary — aspects of a stochastic process of creation that is expressed in ontogenetic circumstances, social evolution, literary works, and filmic works.

The success of a few theories in statistical thermodynamics can be correlated with their selectivity to reality. These are the theories of Boltzmann, Gibbs, and Einstein. The starting point is Carnot’s theory, which defines implicitly the general selection of reality relevant to thermodynamics. The three other theories share this selection, but specify it further in detail. Each of them separates a few main aspects within the scope of the implicit thermodynamic reality. Their success grounds on that selection. Those aspects can (...) be represented by corresponding oppositions. These are: macroscopic – microscopic; elements – states; relational – non-relational; and observable – theoretical. They can be interpreted as axes of independent qualities constituting a common qualitative reference frame shared by those theories. Each of them can be situated in this reference frame occupying a different place. This reference frame can be interpreted as an additional selection of reality within Carnot’s initial selection describable as macroscopic and both observable and theoretical. The deduced reference frame refers implicitly to many scientific theories independent of their subject therefore defining a general and common space or subspace for scientific theories (not for all). The immediate conclusion is: The examples of a few statistical thermodynamic theories demonstrate that the concept of “reality” is changed or generalized, or even exemplified (i.e. “de-generalized”) from a theory to another. Still a few more general suggestions referring the scientific realism debate can be added: One can admit that reality in scientific theories is some partially shared common qualitative space or subspace describable by relevant oppositions and rather independent of their subject quite different in general. Many or maybe all theories can be situated in that space of reality, which should develop adding new dimensions in it for still newer and newer theories. Its division of independent subspaces can represent the many-realities conception. The subject of a theory determines some relevant subspace of reality. This represents a selection within reality, relevant to the theory in question. The success of that theory correlates essentially with the selection within reality, relevant to its subject. (shrink)

Common wisdom, philosophical analysis and psychological research share the view that memory is subjectively positioned toward the past: Specifically, memory enables one to become re-acquainted with the objects and events of his or her past. In this paper I call this assumption into question. As I hope to show, memory has been designed by natural selection not to relive the past, but rather to anticipate and plan for future contingencies -- a decidedly future-oriented mode of subjective temporality. This is not (...) to say memory makes no reference to the past. But, I argue, past-oriented subjectivity is a by-product of a system designed by natural selection to help us face and respond to the "now and the next". I discuss the implications of the proposed temporal realignment for research agendas as well as the potential limitations of measures designed to explore memory by focusing on its retentive capabilities.

Perceivers generally show a poor ability to detect changes, a condition referred to as “Change Blindness” . They are, in addition, “blind to their own blindness”. A common explanation of this “Change Blindness Blindness” is that it derives from an inadequate, “photographical” folk-theory about perception. This explanation, however, does not account for intra-individual variations of CBB across trials. Our study aims to explore an alternative theory, according to which participants base their self-evaluations on two activity-dependent cues, namely search (...) time and perceived success in prior trials. These cues were found to influence self-evaluation in two orthogonal ways: success-feedback influenced self-evaluation in a global, contextual way, presumably by recalibrating the norm of adequacy for the task. Search time influenced it in a local way, predicting the success of a given trial from its duration. (shrink)

Trust has a great potential for furthering our understanding of organizational change and learning. This potential however remains largely untapped. It is argued that two reasons as for why this potential remains unrealized are: (i) A narrow conceptualization of change as implementation and (ii) an emphasis on direct and aggregated effects of individual trust to the exclusion of other effects. It is further suggested that our understanding of the effects of trust on organizational change, should benefit from (...) including effects of trust on the formulation stage. It should also benefit from exploring the structuring effects of trust in organizations. Throughout this chapter, ways to extend current research on trust in organizations are suggested. The chapter also provides examples of relevant contributions where available. In order to capture organizational effects of trust, it is suggested that trust should be studied over longer time intervals, and include several referents of trust, spanning both horizontal and vertical relationships in the organization.

The present article arises from the reflection on the failure of external educational models applied in emerging contexts without considering contextual factors of each town. According to Carnoy (1974) there is a strong tradition between underdeveloped countries of coping the cultural forms and successful models from first world societies, without having prepared beforehand the objective and subjective conditions that would determine its success or failure. The aim of this paper is to analyze the philosophical basis of success behind the Finnish (...) educational system, with the purpose of identify in it, references to overcome problems of educational reality in emerging societies. In this way contribute to the discussion about the failure on adapting external educational models to emerging contexts. It is an exploratory, descriptive and comparative review, and the character of it is bibliographic and qualitative; in addition, it will make use of logical-scientific methods (deductive-inductive) with their respective procedures, supported by phenomenological and hermeneutical philosophical methods. The results of the copy and implementation of changes in education based on successful models from other latitudes, without considering the philosophical and epistemological substratum that sustains it, or preparing the ground for its adaptation, has resulted in poor educational systems that do not respond to the concrete needs of the educational reality of emerging societies, and limit and frustrate the autonomous and original creation of contextualized and relevant educational models too.
