Words and (Possible) Worlds is a study of the relation between language and reality; between words and world. It is a study of reference. Analysing reference often leads to addressing fundamental issues in semantics, metaphysics and epistemology, thus suggesting the close links of reference to these three realms. By utilising the powerful tool of possible-worlds analysis, Alik Pelman carefully explores these links, and elegantly integrates them into a clear and unified model of reference. In the course of his (...) study, Pelman addresses familiar philosophical puzzles (many of which are due to Kripke), for example, Could we discover that Queen Elizabeth was not the daughter of George VI, that is, would we be talking about Queen Elizabeth in this case? Could this table come into existence from a different hunk of wood than the one it was originally made of? Does the term "water" refer to the pink solid H2O on another possible world? (shrink)

The paper proposes a simple method for constructing ontological theories—an ‘ontology generator’. It shows that such a generator manages to produce major existing ontological theories, e.g., Realism, Nominalism, Trope theory, Bundle theory, Perdurantism, Endurantism, Possibilism, Actualism and more. It thus turns out, surprisingly, that all these seemingly unrelated different ontological theories that were designed by thinkers hundreds of years apart, can all be generated using the same simple mechanism. Moreover, this same generator manages to produce entirely novel ontological theories, that (...) fare no worse than existing ones in meeting the same common metaphysical challenges. (shrink)

Functionalism is often used to identify mental states with physical states. A particularly powerful case is Lewis's analytical functionalism. Kripke's view seriously challenges any such identification. The dispute between Kripke and Lewis's views boils down to whether the term ‘pain’ is rigid or nonrigid. It is a strong intuition of ours that if it feels like pain it is pain, and vice versa, so that ‘pain’ should designate, with respect to every possible world, all and only states felt as pain. (...) Hence, in order to settle the dispute, we need to check which of the two – Kripke's use of ‘pain’ as rigid, or Lewis's use of ‘pain’ as nonrigid – better meets this intuition. I show that, despite crucial differences in both their semantic and metaphysical assumptions, surprisingly, both views meet this intuition equally well. Thus it appears that this question of rigidity cannot, in principle, be solved, and so, at least with respect to this particular dispute, the jury is still out on whether mental states are identical to physical states.

Following insights from the New Theory of Reference, it has become widely accepted that theoretical identities like ‘water = H2O' are necessary. However, some have challenged this claim. I propose yet another challenge in the form of a sceptical argument. The argument is based on the contention that the necessity of theoretical identities is dependent upon criteria of identity. Thus, a theoretical identity is necessary given one criterion of identity but contingent given another. Since we do not know which criteria (...) of identity in fact obtain, it follows that, for all we know, theoretical identities may not be necessary. (shrink)

We are on Mars again – the favourite laboratory for philosophical experiments. Our host colleagues introduce us to some Martian stuff referred to as “T”, and ask us to help them to identify T on other possible worlds. Or, technically speaking, we are asked to determine the intension of “T”, i.e., what the term designates with respect to different possible worlds. Following a short series of experiments on the planet, we conclude that the intension of “T” depends upon three factors: (...) (1) The semantic rule linked with the term, i.e., the way in which the term is designed to pick out its referent with respect to different possible worlds (e.g., as a definite description, or as a proper name, or as an actualised description etc.); (2) The properties of the referent of “T” in the actual world; and, (3) What we shall call ‘the metaphysical background of the universe’, i.e., what counts as a thing vs. what counts as a property of things (e.g., whether the universe is such that it contains material objects that merely happen to have their manifest properties, or whether the universe primarily contains manifest objects that merely happen to have their material constitution). As our experiments show, changing the values of any of these variables will result in a change in the reference of the term with respect to different possible worlds, viz., it will result in a change in the intension of the term. We then demonstrate how the three variables are interrelated, and specify how exactly they combine to produce a particular intension of a term. We conclude with a general “formula” that determines what will deserve to be called “T” relative to the different values of the above variables, i.e., we come up with a calculator of intensions. Finally, we also draw some morals about rigidity. (shrink)

Possible world semantics considers not only what an expression actually refers to but also what it might have referred to in counterfactual circumstances. This has proven exceptionally useful both inside and outside philosophy. The way this is achieved is by using intensions. An intension of an expression is a function that assigns to each possible world the reference of the expression in that world. However, the specific intension of terms has been subject to frequent disputes. How is one to determine (...) the intension of a term? Carnap has shown how the intension of a term depends on the type of that term. Two-dimensional semantics has shown how intensions also depend on the actual state of affairs. I will show how, in addition, intensions are no less dependent on metaphysical criteria of identity. Furthermore, I will reveal how these three factors interact to fix the exact intension of a term. In other words, I propose an outline of the overall mechanism by which intensions are being fixed. (shrink)

A commissioned 3-volume (800 pages) in-depth introduction to the philosophy of science, peer-reviewed by 11 specialists. (In Hebrew).

The study of reference often leads to addressing fundamental issues in semantics, metaphysics and epistemology; this suggests that reference is closely linked to the three realms. The overall purpose of this study is to elucidate the structure of some of these links, through a close examination of the “mechanism” of reference. As in many other enquiries, considering the possible (i.e., the modal,) in addition to the actual proves very helpful in clarifying and explicating insights. The reference of a term with (...) respect to possible worlds is commonly called “intension”; so this is a study of intensions. The main contribution of the study is an outline for a “calculator” of intensions. It is argued that the intension of a term is a function of three variables: (a) the way in which the term “picks out” its referent in different possible worlds (semantics); (b) criteria of identity (metaphysics); and (c) the actual state of affairs (actuality). While considering different possible values for these variables, it is demonstrated how the variables combine to generate the term’s intension. In other words, the result is a calculator that when provided with the required values, yields the reference of the term in different possible worlds. By taking into account the possible gap between what we take the values of these variables to be and what they may in fact be, we also gain important insights into the epistemic aspect of reference. In addition, since a rigid designator is a term with constant intension, the proposed thesis provides an elaborate account of rigidity. The first chapter is devoted to the development of the calculator of intensions. Each of the following three chapters elaborates on one aspect of intensions, namely, the semantic, metaphysical and epistemic aspects. In the course of these chapters, various familiar puzzles pertaining to the respective philosophical realms are addressed (many of these puzzles are discussed in Kripke’s Naming and Necessity – a work that considerably inspired this study). In the fifth and last chapter the analysis of intensions is applied to two case-studies from relatively recent philosophical literature: the Kripke-Lewis debate over the identity theory of mind, and the debate over the significance of Donnellan’s referential/attributive distinction. The novel accounts that these applications generate purport to illustrate the importance and originality of the proposed thesis. (shrink)

Judgments of visual resemblance (‘A looks like B’), unlike other judgments of resemblance, are often induced directly by visual experience. What is the nature of this experience? We argue that the visual experience that prompts a subject looking at A to judge that A looks like B is a visual experience of B. After elucidating this thesis, we defend it, using the ‘phenomenal contrast’ method. Comparing our account to competing accounts, we show that the phenomenal contrast between a visual experience (...) that induces the judgment that A looks like B, and a visual experience that does not induce this judgment, is best explained by the fact that the former visually represents B, whereas the latter does not.

Alik Pelman proposes a sceptical challenge to the widely accepted thesis that theoretical identities are necessary. His argument relies on the possibility of the manifest criterion of identity. In this article, we argue that given the necessity of the obtaining of the identity criterion, Pelman’s sceptical argument against the necessity of theoretical identities cannot be effective. By comparing Pelman’s sceptical argument with classical sceptical arguments, it is demonstrated that there is a sense in which classical arguments (...) are effective but not Pelman’s. (shrink)

The purpose of the study is to determine the totality and content of key methodological approaches as conceptual foundations for designing the process of improving human resources of physical culture and sports. The article discusses the key provisions of resource, regional, functional, optimization; attention is focused on the concretization of the immanent principles of these approaches in relation to the problem of optimal management of human resources of physical culture and sports in the regional aspect. The scientific novelty lies in (...) the determination of the methodological contribution to the design of the concept of human resources management of physical culture and sports at the regional level of four basic approaches and their pairwise integration. As a result, the methodological contribution of the basic approaches to the developed concept was revealed and the key importance of their pairwise integration as target, meaningful, methodological guidelines for management was determined.

Depression is a widespread concern in the United States. Neuromodulation treatments are becoming more common but there is emerging concern for racial disparities in neuromodulation treatment utilization. This study focuses on Transcranial Magnetic Stimulation (TMS), a treatment for depression, and the structural and attitudinal barriers that racialized individuals face in accessing it. In January 2023 participants from the Twin Cities, Minnesota engaged in focus groups, coupled with an educational video intervention. Individuals self identified as non-white who had no previous TMS (...) exposure but had tried at least one treatment for their depression. Results revealed that the intervention did not notably change knowledge or stigma about TMS, but attitudes surrounding traveling for treatment changed. Notably, barriers like affordability, frequency of treatment, and lack of knowledge persist. Participants expressed a desire for more information, personal connection, and a tailored educational approach. The study suggests a need for multifaceted strategies to reduce disparities, focusing on education, community-based resources, and policy interventions. Immediate actions that can be taken include the creation of a TMS education program focused on patient engagement and awareness about TMS. (shrink)

Choice Based Credit System (CBCS) is a modern curriculum system of higher education in India which was first introduced by the Academic and Administrative Reforms committee of University Grant Commission (UGC) in 2008 headed by Prof. A. Gnanam. It is a system that promises to bring in holistic development of an individual by providing flexible and multi-disciplinary learning experience. The CBCS provides a cafeteria type approach in which the students can take courses of their choice, learn at their own pace, (...) undergo additional courses and acquire more than the required credits, and adopt an interdisciplinary approach to learning. The courses shall be evaluated on the grading system, which is considered to be better than the conventional marks system. To make the present curriculum uniform, international standard and more developed UGC implement the Choice Based Credit System at higher education level. There are different Universities in the country that have adopted this system through modifying up to 30% of core papers’ syllabus under the proposed UGC curriculum. The major objectives of the study were to explore the nature of the present CBCS curriculum of Zoology and measure the perception level of the students on the present CBCS curriculum of Zoology of Vidyasagar University. The major Findings of the study were suggested that the Vidyasagar University followed the UGC recommended curriculum pattern for framing the CBCS curriculum of Zoology and it has also been found that there was no significant difference in the male and female students’’ perception about CBCS curriculum of zoology at undergraduate level in Vidyasagar University. -/- .

In this article, we explore how deep brain stimulation (DBS) devices designed to “close the loop”—to automatically adjust stimulation levels based on computational algorithms—may risk taking the individual agent “out of the loop” of control in areas where (at least apparent) conscious control is a hallmark of our agency. This is of particular concern in the area of psychiatric disorders, where closed-loop DBS is attracting increasing attention as a therapy. Using a relational model of identity and agency, we consider whether (...) DBS designed for psychiatric regulation may require special attention to agency. To do this, we draw on philosophical work on relational identity and agency, connecting it with reports from people using first-generation DBS devices for depression and obsessive-compulsive disorder. We suggest a way to extend a notion of relational agency to encompass neural devices. (shrink)

Family members can provide crucial support to individuals participating in clinical trials. In research on the “newest frontier” of Deep Brain Stimulation (DBS)—the use of DBS for psychiatric conditions—family member support is frequently listed as a criterion for trial enrollment. Despite the significance of family members, qualitative ethics research on DBS for psychiatric conditions has focused almost exclusively on the perspectives and experiences of DBS recipients. This qualitative study is one of the first to include both DBS recipients and their (...) family members as interview participants. Using dyadic thematic analysis—an approach that takes both the individuals and the relationship as units of analyses—this study analyzes the complex ways in which family relationships can affect DBS trial participation, and how DBS trial participation in turn influences family relationships. Based on these findings, we propose ways to improve study designs to better take family relationships into account, and better support family members in taking on the complex, essential roles that they play in DBS trials for psychiatric conditions.

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

In the first part of this paper I argue that even if at first Alvin Plantinga’s reasons for allowing special divine action seem similar to those of Thomas Aquinas, particularly in De Potentia Dei for allowing miracles, the difference in their metaphysical language makes Aquinas’ account less prone to the objections raised against Plantinga’s. In the second part I argue that Plantinga errs when recurring to quantum mechanics for allowing special divine action, making God to be a cause among causes. (...) Thomas Aquinas, by speaking of primary and secondary causality when referring to God’s activity, avoids taking this step, evading the conclusion that God could be seen as a cause among causes. Aquinas, however, maintains in a statement which goes beyond Plantinga’s, that God’s providence requires the universe to be indeterministic because this indeterministic feature makes the universe more perfect.

Our research focuses on the perception of difference in the evaluations of positive and negative options. The literature provides evidence for two opposite effects: on the one hand, negative objects are said to be more differentiated, on the other, people are shown to see greater differences between positive options. In our study, we investigated the perception of difference between fictitious political candidates, hypothesizing greater differences among the evaluations of favorable candidates. Additionally, we analyzed how positive and negative information affect candidate (...) evaluation, predicting further asymmetries. In three experiments, participants evaluated various candidate profiles presented in a numeric and narrative manner. The evaluation tasks were designed as individual or joint assessments. In all three studies, we found more differentiation between positive than negative options. Our research suggests that after exceeding a certain, relatively small level of negativity, people do not see any further increase in negativity. The increase in positivity, on the other hand, is more gradual, with greater differentiation among positive options. Our findings are discussed in light of cognitive-experiential self-theory and density hypothesis. (shrink)

Medicalization is frequently defined as a process by which some non-medical aspects of human life become to be considered as medical problems. Overdiagnosis, on the other hand, is most often defined as diagnosing a biomedical condition that in the absence of testing would not cause symptoms or death in the person’s lifetime. Medicalization and overdiagnosis are related concepts as both expand the extension of the concept of disease. They are both often used normatively to critique unwarranted or contested expansion of (...) medicine and to address health services that are considered to be unnecessary, futile, or even harmful. However, there are important differences between the concepts, as not all cases of overdiagnosis are medicalizations and not all cases of medicalizations are overdiagnosis. The objective of this article is to clarify the differences between medicalization and overdiagnosis. It will demonstrate how the subject matter of medicalization traditionally has been non-medical (social or cultural everyday life) phenomena, while the subject matter of overdiagnosis has been biological or biomolecular conditions or processes acknowledged being potentially harmful. They also refer to different types of uncertainty: medicalization is concerned with indeterminacy, while overdiagnosis is concerned with lack of prognostic knowledge. Medicalization is dealing with sickness (sick role) while overdiagnosis with disease. Despite these differences, medicalization and overdiagnosis are becoming more alike. Medicalization is expanding, encompassing the more “technical” aspects of overdiagnosis, while overdiagnosis is becoming more ideologized. Moreover, with new trends in modern medicine, such as P4 (preventive, predictive, personal, and participatory) medicine, medicalization will become all-encompassing, while overdiagnosis more or less may dissolve. In the end they may converge in some total “iatrogenization.” In doing so, the concepts may lose their precision and critical sting. (shrink)

Prior research found correlations between reflection test performance and philosophical tendencies among laypeople. In two large studies (total N = 1299)—one pre-registered—many of these correlations were replicated in a sample that included both laypeople and philosophers. For example, reflection test performance predicted preferring atheism over theism and instrumental harm over harm avoidance on the trolley problem. However, most reflection-philosophy correlations were undetected when controlling for other factors such as numeracy, preferences for open-minded thinking, personality, philosophical training, age, and gender. Nonetheless, (...) some correlations between reflection and philosophical views survived this multivariate analysis and were only partially confounded with either education or self-reported reasoning preferences. Unreflective thinking still predicted believing in God whereas reflective thinking still predicted believing that (a) proper names like ‘Santa’ do not necessarily refer to entities that actually exist and (b) science does reveal the fundamental nature of the world. So some robust relationships between reflection and philosophical tendencies were detected even among philosophers, and yet there was clearly more to the link between reflection and philosophy. To this end, demographic and metaphilosophical hypotheses are considered. (shrink)

How can democracy persist among people who have little in common with one another? This longstanding question in democratic theory has increased relevance for recent debates over the preconditions for political unity in diverse societies. Liberals, for example, argue that a shared set of procedures and principles is sufficient to hold together diverse individuals. Critics of liberalism, by contrast, contend that citizens must further share a patriotic attachment to the community in order to feel the solidarity and mutual concern necessary (...) to democracy. I argue that both kinds of argument overemphasize what citizens must share, and occlude consideration of how the sharing necessary to democracy takes place. I develop an account of the activity of sharing by turning to the theories of communication and expression in the works of Hannah Arendt and Ludwig Wittgenstein, and by analyzing conflicts over the Charlottetown Accord in Canada and the publication of The Satanic Verses in Britain. ;At the level of political theory, I advocate a methodological shift from this object-orientation to what we share, toward an activity-orientation to how we share. I argue that what we share is often indeterminate, and is therefore the subject of disagreement rather than concord. Furthermore, we do not need to share any common object: sharing is best understood as a dialogical activity that derives its coherence from the participation of diverse interlocutors. I explore the consequences of the indeterminate and dialogical character of sharing for group identity, collective agency, and mutual respect in the context of feminist and multicultural theory. Yet at the level of political action, a seamless re-orientation to activity is neither possible nor desirable. Both object- and activity-orientations enable certain kinds of first-person experiences that are invaluable for democratic politics. Sharing democracy in conditions of diversity, I conclude, depends not on what we share, but on whether as political agents we can successfully negotiate and sustain a tension between the two orientations to politics that diverse democracy requires: the object-orientation that enables the assertion of commonality and the search for agreement, and the activity-orientation that enables awareness of otherness and celebration of ongoing contestation.

Relationships of physical resemblance to personality similarity and social affiliation have generated considerable discussion among behavioral science researchers. A “twin-like” experimental design explores associations among resemblance in appearance, the Big Five personality traits, self-esteem, and social attraction within an evolutionary framework. The Personality for Professionals Inventory, NEO/NEO-FFI-3, Rosenberg Self-Esteem Scale, and a Social Relationship Survey were variously completed by 45 U-LA pairs, identified from the “I’m Not a Look-Alike” project, Mentorn Media, and personal referrals. The mean U-LA intraclass correlations were (...) negligible for all Big Five personality traits on the PfPI and NEO/NEO-FFI-3. In contrast, mean ri values of.53 and.15 for monozygotic and dizygotic reared-apart twins, respectively, have been reported for these personality measures. The U-LA self-esteem correlation was also below the correlations reported for MZ and DZ reared-together twins. Finally, far fewer U-LAs expressed close social relationships than MZA and DZA twins. The present study extends earlier findings indicating that appearance is not meaningfully related to personality similarity and social relatedness. The criticism that MZ twins are alike in personality because their matched looks invite similar treatment by others is refuted. A more judicious interpretation is reactive genotype-environment correlation, namely that MZ twins’ similar personalities evoke similar reactions from others. MZ twins’ close social relations most likely derive from their perceptions of genetically based within-pair similarities that are lacking in U-LAs. (shrink)

Recently, a number of epistemologists (notably Feldman [2007], [2009] and White [2005], [2013]) have argued for the rational uniqueness thesis, the principle that any set of evidence permits only one rationally acceptable attitude toward a given proposition. In contrast, this paper argues for extreme rational permissivism, the view that two agents with the same evidence may sometimes arrive at contradictory beliefs rationally. This paper identifies different versions of uniqueness and permissivism that vary in strength and range, argues that evidential peers (...) with different interests need not rationally endorse all the same hypotheses, argues that evidential peers who weigh the theoretic virtues differently can sometimes rationally endorse contradictory conclusions, and finally defends the permissivist appeal to standards against objections in the works of Feldman and White.

With the powerful analyses and resources they enable, digital humanities tools have captivated researchers from many different fields who want to use them to study science. Digital tools, as well as funding agencies, research communities, and academic administrators, require researchers to think carefully about how they conceptualize, manage, and store data, and about what they plan to do with that data once a given project is over. The difficulties of developing strategies to address these problems can prevent new researchers from (...) sticking with digital tools and flummox even experienced researchers. To help overcome the data hurdle, we present five principles to help researchers, novice and experienced alike, conceptualize and plan for their data. We illustrate the use of those principles with two digital projects from the history of science, the Embryo Project and the Marine Biological Laboratory History Project, and their associated HPS Repository for data. The principles apply beyond the digital realm, so those who collect and manage data by more traditional means will also find them useful. (shrink)

A great deal of discussion in recent philosophy of language has centered on the idea that there might be hidden contextual parameters in our sentences. But relatively little attention has been paid to what those parameters themselves are like, beyond the assumption that they behave more or less like variables do in logic. My goal in this paper is to show this has been a mistake. I shall argue there are at least two very different sorts of contextual parameters. One (...) is indeed basically like variables in logic, but the other is very different, and much more like overt referring expressions. This result is of interest in its own right, to those of us who are concerned to map out the details of the semantic and pragmatic workings of language. But it will have some wider morals as well. One of the important issues behind the debate over hidden parameters has been how we can posit hidden structure in language, and how far such structure can stray from the intuitive forms and contents speakers see in communication. I shall argue that one sort of hidden parameter is surprisingly close to the contents and forms speakers find intuitive, while another is more remote. I shall show that the.. (shrink)

Since the outbreak of the novel coronavirus disease at the beginning of December 2019, there have been more than 28.69 million cumulative confirmed cases worldwide as of 12th September 2020, affecting over 200 countries and regions with more than 920,463 deaths. The COVID-19 pandemic has been sweeping worldwide with unexpected rapidity. In this paper, a hybrid modelling strategy based on tessellation structure- configured SEIR model is adopted to estimate the scale of the pandemic spread. Building on the data pertaining to (...) the global pandemic transmission over the last six months around the world, key impact factors in the transmission and control procedure have been analysed, including isolation rate, number of the infected cases before taking prevention measures, degree of contact scope, and medical level, so as to capture the fundamental factor influencing the pandemic. The quantitative evaluation allowed us to illustrate the magnitude of risks of pandemic and to recommend appropriate national health policy of prevention measures for effectively controlling both intra- and interregional pandemic spread. Our modelling results clearly indicate that the early-stage preventive measures are the most effective action to be taken to contain the pandemic spread of the highly contagious nature of the COVID-19.
