Objectives To review the extant literature on HIV criminal laws, and to determine the impact of these laws on public health practice.Methods The available research on this topic was obtained and reviewed.Results The extant literature addressed three main topics: people's awareness of HIV criminal laws; people's perceptions of HIV criminal laws; and the potential effects of HIV criminal laws on people's sexual, HIV-status disclosure and healthcare-seeking practices. Within these categories, the literature demonstrated a high level of awareness of HIV criminal (...) laws, but a poor comprehension of these laws. For perceptions, on the whole, the quantitative research identified support for, while the qualitative literature indicated opposition to, these laws. Lastly, the behavioural effects of HIV criminal laws appear to be complex and non-linear.Conclusions A review of the extant literature from a public health perspective leads to the conclusion that HIV criminal laws undermine public health.

It is widely noted that physicalism, taken as the doctrine that the world contains just what physics says it contains, faces a dilemma which, some like Tim Crane and D.H. Mellor have argued, shows that “physicalism is the wrong answer to an essentially trivial question”. I argue that both problematic horns of this dilemma drop out if one takes physicalism not to be a doctrine of the kind that might be true, false, or trivial, but instead an attitude or oath (...) one takes to formulate one’s ontology solely according to the current posits of physics.

What justifies the allocation of funding to research in physics when many would argue research in the life and social sciences may have more immediate impact in transforming our world for the better? Many of the justifications for such spending depend on the claim that physics enjoys a kind of special status vis-a-vis the other sciences, that physics or at least some branches of physics exhibit a form of fundamentality. The goal of this paper is to articulate a conception of (...) fundamentality that can support such justifications. I argue that traditional conceptions of fundamentality in terms of dynamical or ontic completeness rest on mistaken assumptions about the nature and scope of physical explanations. (shrink)

Within the field of quantum gravity, there is an influential research program developing the connection between quantum entanglement and spatiotemporal distance. Quantum information theory gives us highly refined tools for quantifying quantum entanglement such as the entanglement entropy. Through a series of well-confirmed results, it has been shown how these facts about the entanglement entropy of component systems may be connected to facts about spatiotemporal distance. Physicists are seeing these results as yielding promising methods for better understanding the emergence of (...) (the dynamical) spacetime (of general relativity) from more fundamental quantum theories, and moreover, as promising for the development of a nonperturbative theory of quantum gravity. However, to what extent does the case for the entanglement entropy-distance link provide evidence that spacetime structure is nonfundamental and emergent from nongravitational degrees of freedom? I will show that a closer look at the results lends support only to a weaker conclusion, that the facts about quantum entanglement are constrained by facts about spatiotemporal distance, and not that they are the basis from which facts about spatiotemporal distance emerge.

This is a new volume of original essays on the metaphysics of quantum mechanics. The essays address questions such as: What fundamental metaphysics is best motivated by quantum mechanics? What is the ontological status of the wave function? Does quantum mechanics support the existence of any other fundamental entities, e.g. particles? What is the nature of the fundamental space of quantum mechanics? What is the relationship between the fundamental ontology of quantum mechanics and ordinary, macroscopic objects like tables, chairs, and (...) persons? This collection includes a comprehensive introduction with a history of quantum mechanics and the debate over its metaphysical interpretation focusing especially on the main realist alternatives.

Montague and Kaplan began a revolution in semantics, which promised to explain how a univocal expression could make distinct truth-conditional contributions in its various occurrences. The idea was to treat context as a parameter at which a sentence is semantically evaluated. But the revolution has stalled. One salient problem comes from recurring demonstratives: "He is tall and he is not tall". For the sentence to be true at a context, each occurrence of the demonstrative must make a different truth-conditional contribution. (...) But this difference cannot be accounted for by standard parameter sensitivity. Semanticists, consoled by the thought that this ambiguity would ultimately be needed anyhow to explain anaphora, have been too content to posit massive ambiguities in demonstrative pronouns. This article aims to revived the parameter revolution by showing how to treat demonstrative pronouns as univocal while providing an account of anaphora that doesn't end up re-introducing the ambiguity.

There is a standard way of interpreting physicalism. This is as a completeness thesis of some kind. Completeness physicalists believe there is or in principle could be some future physics that provides a complete explanatory or ontological basis for our universe. And this provides a sense in which physics is special among the sciences, the sense in which it is fundamental. This paper contrasts this standard completeness physicalism with what is a more plausible maximality physicalism. Maximality physicalists believe physics is (...) special only in its providing an epistemic framework that is ontologically or explanatorily superior in some respect. This paper shows how completeness physicalists cannot, while maximality physicalists can, provide an adequate explanation of the empirical support for and the pragmatic usefulness of physicalism. It also shows how maximality physicalism is better supported in light of several developments from late twentieth century philosophy of science. (shrink)

Those of us who take skepticism seriously typically have two relevant beliefs: (a) it’s plausible (even if false) that in order to know that I have hands I have to be able to epistemically neutralize, to some significant degree, some skeptical hypotheses, such as the brain-in-a-vat (BIV) one; and (b) it’s also plausible (even if false) that I can’t so neutralize those hypotheses. There is no reason for us to also think (c) that the BIV hypothesis, for instance, is plausible (...) or probably true. In order to take skepticism seriously it’s sufficient to hold (a) and (b); one need not hold (c). Indeed, philosophers who accept (a) and (b) never endorse (c). Show me a philosopher who suspects that he is a brain in a vat and I’ll show you someone who is deranged! That’s one thing that bothers undergraduates in philosophy. They object: why on earth do some philosophers take the BIV hypothesis to pose any threat at all to our beliefs given that those very same philosophers think that there’s no real chance that the BIV hypothesis is true? Sure, the BIV hypothesis is formally inconsistent with my belief that I have hands, so if the former is true then my belief is false. But so what? Why should that bare inconsistency matter so much? Is this strange attitude amongst philosophers the result of some logic fetish infecting the philosophical community? It is sometimes said that the skeptical hypotheses are not only inconsistent with our beliefs but are explanatory of our experiences, which is supposed to make them more of a threat. But students aren’t fooled: although the skeptical hypotheses may attempt to explain why our experience is as it is, it’s the kind of attempt appropriate for science fiction movies that are all special effects and virtually no plot. No one with any sense of reality will take the evil demon hypothesis to be even tenuously explanatory. (shrink)

In the language of second-order logic, first- and second-order variables are distinguished syntactically and cannot be grammatically substituted. According to a prominent argument for the deployment of these languages, these substitution failures are necessary to block the derivation of paradoxes that result from attempts to generalize over predicate interpretations. I first examine previous approaches which interpret second-order sentences using expressions of natural language and argue that these approaches undermine these syntactic restrictions. I then examine Williamson’s primitivist approach according to which (...) second-order sentences are not offered readings in a previously understood language. I argue that the syntactic restrictions alone do not block the derivation of the paradox, unless they are backed by a principled reason that the language cannot be expanded to allow the grammatical substitution of first- and second- order variables. I argue that there is neither a syntactic nor a semantic principle that prohibits such an expansion. (shrink)

The principle of compositionality requires that the meaning of a complex expression remains the same after substitution of synonymous expressions. Alleged counterexamples to compositionality seem to force a theoretical choice: either apparent synonyms are not synonyms or synonyms do not syntactically occur where they appear to occur. Some theorists have instead looked to Frege’s doctrine of “reference shift” according to which the meaning of an expression is sensitive to its linguistic context. This doctrine is alleged to retain the relevant claims (...) about synonymy and substitution while respecting the compositionality principle. Thus, Salmon (Philos Rev 115(4):415, 2006) and Glanzberg and King (Philosophers’ Imprint 20(2):1–29, 2020) offer occurrence-based accounts of variable binding, and Pagin and Westerståhl (Linguist Philos 33(5):381–415, 2010c) argue that an occurrence-based semantics delivers a compositional account of quotation. Our thesis is this: the occurrence-based strategies resolve the apparent failures of substitutivity in the same general way as the standard expression-based semantics do. So it is a myth that a Frege-inspired occurrence-based semantics affords a genuine alternative strategy. (shrink)

Jaegwon Kim has argued that unless mental events are reducible to subvening physical events, they are at best overdeterminers of their effects. Recently, nonreductive physicalists have endorsed this consequence claiming that the relationship between mental events and their physical bases is tight enough to render any such overdetermination nonredundant, and hence benign. I focus on instances of this strategy that appeal to the notion of constitution. Ultimately, I argue that there is no way to understand the relationship between irreducible mental (...) events and their physical bases such as to both eliminate causal redundancy and preserve the efficacy of mental events.

If you retain your belief upon learning that a large number and percentage of your recognized epistemic superiors disagree with you, then what happens to the epistemic status of your belief? I investigate that theoretical question as well has the applied case of philosophical disagreement—especially disagreement regarding purely philosophical error theories, theories that do not have much empirical support and that reject large swaths of our most commonsensical beliefs. I argue that even if all those error theories are false, either (...) (a) the average philosopher’s true commonsensical beliefs are epistemically impoverished, or (b) a good portion of philosophy is bunk and philosophers should give up most of their error theories despite the fact that their supporting arguments are generally as good as or even better than other philosophical arguments.

Aristotle’s theory of human happiness in the Nicomachean Ethics explicitly depends on the claim that contemplation (theôria) is peculiar to human beings, whether it is our function or only part of it. But there is a notorious problem: Aristotle says that divine beings also contemplate. Various solutions have been proposed, but each has difficulties. Drawing on an analysis of what divine contemplation involves according to Aristotle, I identify an assumption common to all of these proposals and argue for rejecting it. (...) This allows a straightforward solution to the problem and there is evidence that Aristotle would have adopted it. (shrink)

Fifteen dialogues drawn from the highly acclaimed BBC series review the tenets and theories of moral philosophy, poliitcal philosophy, the philosophy of language, and the philosophy of science.

Beginning with the death of Socrates in 399 BC, and following the strand of philosophical inquiry through the centuries to recent figures such as Bertrand Russell and Wittgenstein, Bryan Magee's conversations with fifteen contemporary writers and philosophers provide an accessible and exciting account of Western philosophy and its greatest thinkers. With contributions from A. J. Ayer, Bernard Williams, Martha Nussbaum, Peter Singer, and John Searle, the book is not only an introduction to the philosophers of the past, but gives (...) an invaluable insight into the view and personalities of some of the most influential philosophers of the twentieth century.

Cooperative child care among humans, where individuals other than the biological mother (allomothers) provide care, may increase a mother’s fertility and the survivorship of her children. Although the potential benefits to the mother are clear, the motivations for allomothers to provide care are less clear. Here, we evaluate the kin selection allomothering hypothesis using observations on Hadza hunter-gatherers collected in ten camps over 17 months. Our results indicate that related allomothers spend the largest percentage of time holding children. The higher (...) the degree of relatedness among kin, the more time they spend holding, supporting the hypothesis of nepotism as the strongest motivation for providing allomaternal care. Unrelated helpers of all ages also provide a substantial amount of investment, which may be motivated by learning to mother, reciprocity, or coercion. (shrink)

This semester-long research project examined the use of social studies trade books to thematically teach about six individuals who served as change agents in the United States during the late 19th century and early 20th century. Three of the individuals were African American men, Robert Smalls, Frederick Douglass, and John Roy Lynch, who took civic action to address racial discrimination faced by the Black community in the half century following the U.S. Civil War. The other three indivduals were women women, (...) Ida B. Wells, Clara Lemlich, and Jane Addams, who challenged social inequities and injustices within their communities. Over the course of the semester-long research project, sixth-grade U.S. history students read selected trade books, examined primary sources, completed graphic organizers, and crafted writing assessments about each of the six individuals. Students demonstrated complex historical thinking, integrated economic and civic thinking, and communicated thematic ideas of systemic oppression of minorities, women, and the poor. They struggled to make connections between examples of historic oppression and contemporary examples of societal oppression. (shrink)

Goodman and Lederman (2020) argue that the traditional Fregean strategy for preserving the validity of Leibniz’s Law of substitution fails when confronted with apparent counterexamples involving proper names embedded under propositional attitude verbs. We argue, on the contrary, that the Fregean strategy succeeds and that Goodman and Lederman’s argument misfires.

Cross-cultural sex differences in mobility and harm avoidance have been widely reported, often emphasizing fitness benefits of long-distance travel for males and high costs for females. Data emerging from adults in small-scale societies, however, are challenging the assumption that female mobility is restricted during reproduction. Such findings warrant further exploration of the ontogeny of mobility. Here, using a combination of machine-learning, mixed-effects linear regression, and GIS mapping, we analyze range size, daily distance traveled, and harm avoidance among Hadza foragers during (...) middle childhood and adolescence. Distance traveled increased with age and, while male adolescents had the longest daily ranges, average daily distance traveled by each sex was similar. We found few age- or sex-related patterns in harm-avoidant responses and a high degree of individual variation. When queried on the same issues, children and their parents were often in alignment as to expectations pertaining to harm avoidance, and siblings tended to behave in similar ways. To the extent that sex differences in mobility did emerge, they were associated with ecological differences in physical threats associated with sex-specific foraging behaviors. Further, we found no strong association between harm avoidance and mobility. Young Hadza foragers of both sexes are highly mobile, regardless of how harm avoidant they are. Taken together, our findings indicate that the causal arrows between harm avoidance and mobility must be evaluated in ecologically specific frameworks where cultural expectations of juvenile mobility can be contextualized.

A central dispute in understanding Frege’s philosophy concerns how the sense of a complex expression relates to the senses of its component expressions. According to one reading, the sense of a complex expression is a whole built from the senses of the component expressions. On this interpretation, Frege is an early proponent of structured propositions. A rival reading says that senses compose by functional application: the sense of a complex expression is the value of the function denoted by its functional (...) component for the arguments denoted by its remaining components. I argue that two non-negotiable Fregean theses entail that senses compose by functional application. One thesis is that referents compose by functional application. The other thesis is that an expression in an indirect context refers to its customary sense. (shrink)

The COVID-19 pandemic introduced many restrictions to in-person interactions, and remote social interactions may be especially important for managing loneliness when such restrictions are in place. However, it is unclear how social interactions are related to loneliness when in-person interactions are limited. Data were collected between February 2021 and March 2022 from a sample of 581 university students. Participants reported their loneliness and participation in positive in-person or remote social interactions each day for 14 days. Results from dynamic structural equation (...) models showed that participants felt less lonely than they usually felt on the days they engaged in positive remote interactions at the within-person level. Moreover, participants generally felt less lonely when engaging more frequently in remote interactions, but only when in-person interactions were restricted (between-person level). Some of these results varied by changing COVID-19 restrictions. Finally, for participants who felt lonelier in general, the effect of positive in-person and remote interactions on loneliness was less strong. These findings suggest that social interactions may buffer loneliness but are not as impactful for those who experience greater loneliness. (shrink)

"What are the ontological implications of quantum theories, that is, what do they tell us about the fundamental objects that make up our world? How should quantum theories make us reevaluate our classical conceptions of the basic constitution of material objects and ourselves? Is there fundamental quantum nonlocality?

It is a way of interpreting quantum theories so that the central object they describe is (...) the quantum wave function, interpreted as a field, and that the nonseparability and nonlocality we seem to find in quantum mechanics are ultimately manifestations of a more intuitive, separable and local picture in higher dimensions. quantum mechanics, quantum field theory, wave function, wave function realism, measurement problem, macro-object problem, primitive ontology, quantum entanglement, quantum nonlocality, quantum ontology"--.

This is a revised and enlarged version of Bryan Magee's widely praised study of Schopenhauer, the most comprehensive book on this great philosopher. It contains a brief biography of Schopenhauer, a systematic exposition of his thought, and a critical discussion of the problems to which it gives rise and of its influence on a wide range of thinkers and artists. For this new edition Magee has added three new chapters and made many minor revisions and corrections throughout. This new (...) edition will consolidate the book's standing as the definitive study of Schopenhauer. (shrink)

There is a long history of using facts about disagreement to argue that many of our most precious beliefs are false in a way that can make a difference in our lives. In this essay I go over a series of such arguments, arguing that the best arguments target beliefs that meet two conditions: (i) they have been investigated and debated for a very long time by a great many very smart people who are your epistemic superiors on the matter (...) and have worked very hard under optimal circumstances to figure out if the belief is true, and (ii) as far as you know these people have not come to any significant agreement on the belief and as far as you know those who agree with you are not, as a group, in a better position to judge the belief than those who disagree with you.

Bryan W. Van Norden lambastes academic philosophy for its Eurocentrism and insularity and challenges educational institutions to live up to their cosmopolitan ideals. Taking Back Philosophy is at once a manifesto for multicultural education, an accessible introduction to Confucian and Buddhist philosophy, and a defense of the value of philosophy.

By considering the epistemology and relations among certain philosophical problems, I argue for a disjunctive thesis: either (1) it is highly probable that there are (i) several (ii) mutually independent philosophical reductios of highly commonsensical propositions that are successful—so several aspects of philosophy have succeeded at refuting common sense—or (2) there is enough hidden semantic structure in even simple sentences of natural language to make philosophers highly unreliable at spotting deductive validity in some of the simplest cases—so we are much (...) worse at logic than we think and cannot, in general, know when our own arguments are valid. The untoward consequences of each disjunct are explained. (shrink)

This paper argues for the concept of a decolonial humanism at the heart of C.L.R. James’s theoretical and political engagements. In exploring the concept of decolonial humanism, the paper moves through three major sections dealing with some of the definitive epistemic and political aspects of James’s work: a critique of Enlightenment Humanism and European Marxism without disavowing the aspirations of universal human emancipation; James’s work with the Johnson-Forest Tendency, the Pan-Africanist movement, and his attempts at labor organizing in Trinidad first (...) alongside Eric Williams in the People’s National Movement and later in his own Workers and Farmer’s Party ; and the practicality of decolonial humanism in terms of its adoption by Tim Hector and the Antigua Caribbean Liberation Movement.

Over the past several years, the human rights implications of climate change have become more evident. While extreme weather events and slow onset changes caused by climate change affect the exercise of human rights, the implementation of climate change policies - in relation to both mitigation and adaptation - may also lead to the infringement of the rights of indigenous peoples and local communities. Despite this recognition by the UN Human Rights Council and other bodies, the international climate change regime (...) has failed to address these implications, recognizing only in 2010 the importance for parties to respect human rights in the implementation of the Framework Convention. The adoption of the Durban Platform for Enhanced Action (ADP), together with the reform of existing mechanisms and the operationalization of new institutions, offers several opportunities to ensure the adequate fulfillment of human rights obligations under the Convention. In this commentary, we highlight four concrete options available to the parties in the upcoming negotiations to guarantee the respect of substantial and procedural rights of all the stakeholders and to offer a redress mechanism in the case of loss and damages caused by climate change.

I have taken the traditional problem of the seeming interdependence of identity concepts and essentialistic concepts and the attendant difficulties with circularity as a starting point in my consideration of recent attempts to provide accounts ofde re essences. Having distinguished between theories of individual and generic essences, I have shown how a linguistic device based upon a new approach to referring expressions has, perhaps, provided some advance in the understanding of individualde re essences. I have argued that, however efficacious these (...) linguistic devices may be in dealing with individual essences, they are of no help in dealing with generic essences. I considered, therefore, one of the recent attempts to use science as the arbiter ofde re essences and concluded that such attempts will not, ultimately, solve the traditional problem of circularity. That problem remains, arising in different forms to thwart different attempts to account forde re generic essences. (shrink)

Realists wanting to capture the facts of quantum entanglement in a metaphysical interpretation find themselves faced with several options: to grant some species of fundamental nonseparability, adopt holism, or to view localized spacetime systems as ultimately reducible to a higher-dimensional entity, the quantum state or wave function. Those adopting the latter approach and hoping to view the macroscopic world as grounded in the quantum wave function face the macro-object problem. The challenge is to articulate the metaphysical relation obtaining between three-dimensional (...) macro-objects and the wave function so that the latter may be seen in some sense as constituting the former. This paper distinguishes several strategies for doing so and defends one based on a notion of partial instantiation. (shrink)

Ecological concern has recently prompted efforts to assess the economic value of ecological functions: the “work of nature” must no longer be taken for granted as a free amenity, but priced and accounted for as “natural capital.” Critiques of this approach tend to defend nature’s intrinsic value against intrusions of economic logic, but fail to articulate a compelling politics in response. I here argue that nature ought indeed to be brought in to the realm of political economy, but question the (...) category of natural capital: instead, extending the insights of feminist theorists regarding undervalued forms of production, I articulate an expanded idea of hybrid labor that understands the “work of nature” as a collective, distributed undertaking of humans and nonhumans acting to reproduce, regenerate, and renew a common world. This approach poses the value of nature as inherently political and suggests the potential for new forms of more-than-human politics. (shrink)

The concept of sustainability has become an important—and contested—term in politics prior to its being given a clear, academic meaning, resulting in disciplinary turf wars over defining the term. The conflict, with mainly economists on one side and ecologists and philosophers on the other, has centered on the difference between “strong” and “weak” sustainability. Weak sustainability requires only the protection of wealth across generations, while strong sustainability requires also the protection of ecophysical features of the environment. It is shown that (...) weak sustainability, and solutions meant to achieve it, when applied to the parable of the tragedy of the commons, cannot protect resources whether owned or held in common. A communitarian approach, joined with an idea of communities as multigenerational entities and a commitment to a deliberative process seeking sustainability, can track a path toward strong sustainability.

Obstacles to achieving a global climate treaty include disagreements about questions of justice raised by the UNFCCC's principle that countries should respond to climate change by taking cooperative action "in accordance with their common but differentiated responsibilities and respective capabilities and their social and economic conditions". Aiming to circumvent such disagreements, Climate Change Justice authors Eric Posner and David Weisbach argue against shaping treaty proposals according to requirements of either distributive or corrective justice. The USA's climate envoy, Todd Stern, takes (...) a similar position. In this article I explain the practical and theoretical drawbacks of Posner & Weisbach's welfarist perspective and propose an alternative. I show that their arguments fail to rule out John Rawls' non-utilitarian, political conception of international justice and human rights, the Law of Peoples. On this basis I develop a conception of climate justice that highlights implications of some of Rawls' principles and adds a principle for determining fair shares of climate -treaty-related benefits and burdens. I propose this conception as a moral framework for negotiating a treaty that would promote human welfare consistently with requirements of justice, and I argue that a treaty proposal satisfying these requirements could best satisfy Posner & Weisbach's own feasibility criteria.
