BackgroundChildhood adversity is linked to adverse health in adulthood. One posited mechanistic pathway is through physiological responses to acute stress. Childhood adversity has been previously related to both exaggerated and blunted physiological responses to acute stress, however, less is known about the psychological mechanisms which may contribute to patterns of physiological reactivity linked to childhood adversity.ObjectiveIn the current work, we investigated the role of challenge and threat stress appraisals in explaining relationships between childhood adversity and cortisol reactivity in response to (...) an acute stressor.MethodsUndergraduate students completed an online survey that included general demographic information and the Risky Families Questionnaire 24 h before a scheduled lab visit. In the lab, a research assistant collected a baseline salivary cortisol sample. Following the baseline period, participants were read instructions for the Trier Social Stress Test, a validated psychological lab stressor. Next, they completed a challenge vs. threat task appraisal questionnaire and completed the speech and math portion of the TSST. Twenty minutes following the start of the TSST, a second salivary sample was collected to measure changes in salivary cortisol following the TSST.ResultsLinear regression analyses adjusted for age, sex, childhood socioeconomic status, and baseline cortisol levels, showed childhood adversity associated with changes in cortisol levels [B = –0.29 t = –2.35, p = 0.02, R2=0.07]. Linear regression analyses controlling for age, sex, and childhood SES showed childhood adversity associated with both challenge [B = –0.52 t = –5.04, p < 0.001, R2=0.24] and threat [B = 0.55 t = 5.40, p < 0.001, R2=0.27] appraisals. Significant indirect effects of childhood trauma on cortisol reactivity were observed through challenge appraisals [B = –0.01 ], and threat appraisals [B = –0.01 ].ConclusionChildhood adversity may contribute to blunted cortisol reactivity, a pattern of response which is linked to obesity, addiction, and other behavior-related diseases. Our findings suggest that this relationship is in part a product of stress appraisals. (shrink)

BackgroundChildhood abuse increases risk for high levels of distress in response to future stressors. Interpersonal social support is protective for health, particularly during stress, and may be particularly beneficial for individuals who experienced childhood abuse.ObjectiveInvestigate whether childhood abuse predicts levels of posttraumatic stress disorder (PTSD) symptoms related to the COVID-19 pandemic, and test whether the perceived availability of social companionship preceding the pandemic moderates this relationship.MethodsDuring Phase 1, adults (N= 120; AgeM[SD] = 19.4 [0.94]) completed a retrospective measure of childhood (...) adversity along with a measure of perceived availability of opportunities for social engagement immediately preceding the pandemic. Two weeks after the COVID-19 pandemic declaration, participants completed the Impact of Event Scale-Revised (IES-R) with respect to the pandemic. Hierarchical linear regression analyses examined the interaction between childhood abuse and the perceived availability of social companionship preceding the pandemic as a predictor of PTSD symptoms.ResultsAdjusting for covariates, the interaction between childhood abuse and perceived availability of others to engage with before the onset of the pandemic was a significant predictor of IES-hyperarousal (β = −0.19,t= −2.06,p= 0.04, ΔR2= 0.032, CI: [−0.31 to −0.01]).ConclusionLevels of perceived opportunities for social companionship before the pandemic associates with levels of hyperarousal related to the pandemic, particularly for individuals who experienced high levels of childhood abuse. More research is needed to understand how to mitigate the higher levels of distress related to the pandemic for these individuals in order to reduce risk for future psychiatric disorders. (shrink)

For years, experimental philosophers have attempted to discern whether laypeople find free will compatible with a scientifically deterministic understanding of the universe, yet no consensus has emerged. The present work provides one potential explanation for these discrepant findings: People are strongly motivated to preserve free will and moral responsibility, and thus do not have stable, logically rigorous notions of free will. Seven studies support this hypothesis by demonstrating that a variety of logically irrelevant (but motivationally relevant) features influence compatibilist judgments. (...) In Study 1, participants who were asked to consider the possibility that our universe is deterministic were more compatibilist than those not asked to consider this possibility, suggesting that determinism poses a threat to moral responsibility, which increases compatibilist responding (thus reducing the threat). In Study 2, participants who considered concrete instances of moral behavior found compatibilist free will more sufficient for moral responsibility than participants who were asked about moral responsibility more generally. In Study 3a, the order in which participants read free will and determinism descriptions influenced their compatibilist judgments—and only when the descriptions had moral significance: Participants were more likely to report that determinism was compatible with free will than that free will was compatible with determinism. In Study 3b, participants who read the free will description first (the more compatibilist group) were particularly likely to confess that their beliefs in free will and moral responsibility and their disbelief in determinism influenced their conclusion. In Study 4, participants reduced their compatibilist beliefs after reading a passage that argued that moral responsibility could be preserved even in the absence of free will. Participants also reported that immaterial souls were compatible with scientific determinism, most strongly among immaterial soul believers (Study 5), and evaluated information about the capacities of primates in a biased manner favoring the existence of human free will (Study 6). These results suggest that people do not have one intuition about whether free will is compatible with determinism. Instead, people report that free will is compatible with determinism when desiring to uphold moral responsibility. Recommendations for future work are discussed. (shrink)

We propose a friendly amendment to integrative experiment design (IED), adversarial-collaboration IED, that incentivizes research teams from competing theoretical perspectives to identify zones of the design space where they possess an explanatory edge. This amendment is especially critical in debates that have high policy stakes and carry a strong normative-political charge that might otherwise prevent free exchange of ideas.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:African American Theological Ethics: A Reader ed. by Peter J. Paris and Julius CrumpCory J. MayAfrican American Theological Ethics: A Reader Edited by Peter J. Paris and Julius Crump LOUISVILLE, KY: WESTMINSTER JOHN KNOX PRESS, 2015. 350 PP. $45.00African American Theological Ethics: A Reader (AATE) is a thought-provoking title that piqued my interest upon first sight. I am an African American Christian who studies African American Christianity, culture, (...) history, and black theology. I wondered how the book would discuss African American theological ethics in terms of its articulation, embodiment, and practice. I also had reservations regarding the book's structure, the diversity of themes emphasized, and the balance between discussion of theology and of ethics. A few questions surfaced as I reflected upon the contents of the book. How is the term "theology" defined? Would the book discuss the particular ethical systems derived from monotheistic and polytheistic religions? How have African Americans contextualized their ethics in relation to God(s)? What is the central role of God(s) in this volume?The aim of the editors "is to provide a collection of resources that depict a broad range of theological and ethical reasoning that African Americans developed during two centuries of slavery, a subsequent century of racial segregation and discrimination, and another half century of continuing inequalities of opportunity and achievement" (xvii–xviii). Thus, the book has a strong sociopolitical emphasis. The reader should not expect theological ethics emphasizing the worship of God(s), religious doctrines, or proper religious living. Rather, AATE is a book of loosely interpreted political theologies and sociopolitical theological ethics. The themes of liberation, oppression, race, slavery, and white supremacy are governing hermeneutics that saturate the book's content. As Peter Paris and Julius Crump suggest, "it is important to note that African American theological ethics is not an abstract theoretical enterprise. Rather, it is a form of inquiry that is clearly related to African American studies in history and sociology both of which either imply or reveal a normative bias for racial justice" (xviii).AATE is a collection of thirty-seven essays and excerpts written by influential thinkers in African American history. Works are presented by such popular figures as Ida B. Wells-Barnett, Martin Luther King Jr., Booker T. Washington, and W.E.B. DuBois. The first four sections of the book are ethical in their approaches and display works emphasizing opposition to white supremacy. Part 1, titled "Opposing the Doctrine of White Supremacy," has a solitary essay from Martin R. Delany's work, The Origin of Race and Colour. Parts 2, 3, and 4—"Opposing Slavery," "Opposing Racial Segregation," and "Opposing Racial Discrimination," respectively—contain works from Shirley Chisholm, Barack [End Page 217] Obama, Adam Clayton Powell Jr., Barbara Jordan, and more. The last two parts change the focus of the book from the theme of opposition and theologically center the discourse on African American ingenuity toward different aspects of life. Part 5 assembles essays from scholars such as Jacquelyn Grant and James Cone under the title of "African American Religious Creativity." The last section displays essays from James Weldon Johnson and Peter J. Paris under the banner of "African American Themes and Perspectives."AATE is a good anthology of discourses that have a strong emphasis on social justice. It would be greatly complemented by other selections that emphasize African American theological ethics apart from sociopolitical issues. It is an informative book that contributes to the genre of African American anthologies; it would strengthen any introductory course on African American theology and is beneficial for anyone seeking broad exposure to the development of African American theological ethics. AATE could be read alongside titles such as Katie G. Cannon and Anthony B. Pinn's The Oxford Handbook of African American Theology, or Paul E. Johnson's African American Christianity: Essays in History.Cory J. MayThe University of AberdeenCopyright © 2017 Society of Christian Ethics... (shrink)

Moral cognition, by its very nature, stems from intuitions about what is good and bad, and these intuitions influence moral assessments outside of conscious awareness. However, because humans evolved a shared set of moral intuitions, and are compelled to justify their moral assessments as good and rational (even erroneously) to others, moral virtue and moral progress are still possible.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The African American Challenge to Just War Theory: A Christian Approach by Ryan P. CummingCory J. MayThe African American Challenge to Just War Theory: A Christian Approach Ryan P. Cumming new york: palgrave macmillan, 2013. 239 pp. $95.00The provocative title of Ryan Cumming’s The African American Challenge to Just War Theory: A Christian Approach builds subtle tension with regard to how a European American scholar has articulated an (...) interpretation of African American views regarding war. In the end, however, the title of the book appears to be a bit misleading.Cumming believes traditional just war theory has been articulated primarily by those within the politicoreligious and sociocultural majority of the Western (white) world. These various traditions have at times created, sustained, and overlooked forms of inequality and oppression as they sought to establish national security and democracy in foreign lands. For Cumming, this has occurred because these traditions have neglected proper consideration toward, dialogue with, and support for the marginalized of the world. Therefore, the partial aim of Cumming’s book “is not to problematize war, but to problematize just war theory and to offer directions for correcting these deficiencies” (3). Cumming seeks to evaluate various aspects of African American political and religious thought as a means to correcting these deficiencies created by the European or European American elite.For Cumming, African Americans are representative of the marginalized, a powerless people within a powerful nation who have created traditions of critical thought, participation, and protest regarding the political affairs of the United States. They therefore embody a unique dual identity that “has encouraged identification with other marginalized groups across the globe. They thus displayed a globalized political perspective long before the realm of politics itself became globalized” (4–5). The dual identity of African Americans has been created from, and creates, what is referred to as the “hermeneutic of suspicion”—the critical way of thinking and living in the world that allows the marginalized to evaluate the thoughts and actions of the elite in ways the elite’s self-reflection cannot accomplish.The major difficulty of the book resides in the fact that African American voices assume a subjugated position to their European and European American counterparts. Only one of the book’s five chapters specifically engages African Americans, making it seem as if African American thought is merely an [End Page 201] addendum to Cumming’s critique of European and European American scholars. He provides a rather general and selective overview of African American views regarding government, politics, and war, employing the voices of Martin Luther King Jr., Manning Marable, Benjamin E. Mays, Howard Thurman, Henry McNeal Turner, and Cornel West, among others; Cumming appears to have a special affinity for liberation theology and James Cone. Readers knowledgeable about African American thought may question whether Cumming could have further distinguished political theologies within African American Christianity, specifically concentrating on the diversity and development of African American reflection upon just war theory.Although African American voices are not at the forefront of his argument, Cumming nevertheless provides an impressively detailed introductory discussion of traditional Christian thought about just war, including basic theories of jus ad bellum (decisions made before war), jus in bello (conduct during war), and jus post bellum (the ending of war and potential outcome) according to the likes of Augustine of Hippo, Thomas Aquinas, Hugo Grotius, and the School of Salamanca: Francisco de Vitoria and Francisco Suarez. He also engages a wide variety of contemporary theorists regarding America’s involvement in various global wars, including Vietnam, Iraq, and the war on terror. Cumming’s challenge to the theoretical stances of Europeans and European American thinkers is well worth the effort, encouraging them to consider sincere dialogue with the marginalized of the world—beginning with African Americans.Cory J.

What does it mean to consider the world of AI through a Christian lens? Rapid developments in AI continue to reshape society, raising new ethical questions and challenging our understanding of the human person. Encountering Artificial Intelligence draws on Pope Francis’ discussion of a culture of encounter and broader themes in Catholic social thought in order to examine how current AI applications affect human relationships in various social spheres and offers concrete recommendations for better implementation. The document also explores questions (...) regarding personhood, consciousness, and the kinds of relationships humans might have with even the most advanced AI. Through these discussions, this book investigates the theoretical and practical challenges to interpersonal encounter raised by the age of AI.

In June 2020, representatives of eight photography organizations addressed ongoing challenges to the industry by introducing the “Photo Bill of Rights,” asserting “the rights of all lens-based workers and defining actions that build a safer, healthier, more inclusive, and transparent industry.” The bill centers what “lens-based workers” are owed by the media organizations that employ them. This study analyzes the bill’s contents and the explicit and implicit values within it, finding that the bill presents a normative view of the work (...) environment lens-based workers should expect as a baseline. In so doing, the bill connects what lens-based workers owe their respective publics to what their employers owe those same workers. The bill highlights the enabling environment that these workers need to satisfy their obligations to the public. The bill reminds employers of their duty to create an equitable environment that can enable the fulfillment of public responsibility. (shrink)

The present article proposes an integration between cultural psychology and developmental science. Such an integration would draw on the cultural-psychology principle of culture-psyche interactions, as well as on the developmental-science principle of person↔︎context relations. Our proposed integration centers on acculturation, which is inherently both cultural and developmental. Specifically, we propose that acculturation is governed by specific transactions between the individual and the cultural context, and that different types of international migrants (e.g., legal immigrants, undocumented immigrants, refugees, asylum seekers, crisis migrants) (...) encounter quite different culture-psyche interactions and person↔︎context relations. We outline the ways in which various acculturation-related phenomena, such as acculturation operating at macro-level versus micro-level time scales, can be viewed through cultural and developmental lenses. The article concludes with future directions in research on acculturation as an intersection of cultural and developmental processes. (shrink)

Hypocretin regulates brain reward function and cocaine consumption in rats. The hypocretinergic (Hcrt) system is implicated in energy homeostasis, feeding and sleep regulation. Hypocretinergic cell bodies are located in the lateral hypothalamus (LH) and project throughout the brain. The aim of the present studies was to investigate the role of the Hcrt system in regulating brain reward function and the reinforcing properties of cocaine in rats. Intracranial self-stimulation (ICSS) thresholds provide an accurate measure of brain reward function in rats. Here (...) we show that a single injection of Hcrt-1 (5 µg icv) induced persistent, long-lasting elevations in ICSS thresholds in drug-naïve rats. Indeed, Hrct-1 elevated ICSS thresholds for 36 h, with peak elevations between 6 and 12 hours after injection. Hrct-1-induced threshold elevations were attenuated by an antibody known to neutralize the binding of hcrt-1 to its receptors. Taken together, these observations suggest that Hrct-1 negatively regulates brain reward function in rats. Because Hrct-1 negatively regulates brain reward function, we hypothesized that it may attenuate the increased brain reward function usually observed after cocaine consumption, and thereby alter cocaine self-administration behavior. A daily injection of Hrct-1 (1 µg icv), for 4 consecutive days, slightly increased cocaine self-administration (0.25 mg/infusion) in rats. Overall, these data demonstrate that Hrct-1 negatively regulates brain reward function, and as such may indirectly alter cocaine self-administration. Given the well-established role of hypocretin neurons in regulating feeding behavior and sleep, we hypothesize that hypocretinergic regulation of brain reward function may provide a mechanism by which appropriate and competing behaviors (e.g. sleep or feeding) may be engaged to maintain energy homeostasis.

Elevations in brain stimulation reward (BSR) thresholds have been observed in rats undergoing nicotine withdrawal and have been proposed as a sensitive measure of the negative affective state associated with nicotine withdrawal. mGluR are presynaptic autoreceptors that decrease glutamate release when stimulated. The aim of this study was to examine the role of glutamate neurotransmission in nicotine dependence. The mGluR agonist LY314582 (2.5–7.5 mg/kg) precipitated nicotine withdrawal as measured by elevations in BSR thresholds in nicotine-treated rats but not in controls. (...) It was hypothesized that LY314582 precipitated nicotine withdrawal by decreasing glutamatergic tone at postsynaptic glutamate receptors. Therefore, the effects of MPEP (0.5–2 mg/kg), an mGluR antagonist, and MK-801 (0.01–1 mg/kg), an NMDA receptor antagonist, were examined. MPEP elevated BSR thresholds by an equal magnitude in control and nicotine-treated rats. At low doses, MK-801 (0.01–0.2 mg/kg) lowered BSR thresholds to a similar extent in control and nicotine-treated rats. At higher doses, MK-801 (0.25–1 mg/kg) disrupted performance in nicotine-treated and control rats. These data indicate that mGluR and NMDA receptors regulate BSR in opposite directions in non-dependent animals, and chronic nicotine treatment does not alter these effects. Most importantly, the data demonstrate that the mGluR is involved in nicotine dependence, but mGluR and NMDA receptors do not mediate mGluR actions in nicotine dependence. (shrink)

In virtue of what do some considerations count in favor or against actions? Some philosophers have recently been interested in hybrid answers to this question. For instance, it might be that some facts about reasons are brute, and some are explained in terms of agents’ acts of will. Such views face a challenge: they need a story about how reasons grounded in one way combine with reasons grounded in other ways to yield overall verdicts about what to do. This paper (...) assesses the two most prominent accounts of how that happens, and offers an alternative that captures what's most plausible about each. (shrink)

What features will something have if it counts as an explanation? And will something count as an explanation if it has those features? In the second half of the 20th century, philosophers of science set for themselves the task of answering such questions, just as a priori conceptual analysis was generally falling out of favor. And as it did, most philosophers of science just moved on to more manageable questions about the varieties of explanation and discipline-specific scientific explanation. Often, (...) such shifts are sound strategies for problem-solving. But leaving fallow certain basic conceptual issues can also result in foundational debates. (shrink)

Hans Reichenbach made a bold and original attempt to ‘vindicate’ induction. He proposed a rule, the ‘straight rule’ of induction, which would guarantee inductive success if any rule of induction would. A central problem facing his attempt to vindicate the straight rule is that too many other rules are just as good as the straight rule if our only constraint on what counts as ‘success’ for an inductive rule is that it is ‘asymptotic’, i.e. that it converges in the (...) limit to the true limiting frequency (of some type of outcome O in a sequence of events) whenever such a limiting frequency exists. In this paper I consider the consequences of requiring speed-optimality of asymptotic methods, that is, requiring that inductive methods must get to the truth as quickly as possible. Two main results are proved: (1) the straight rule is speed-optimal; (2) there are (uncountably) many non-speed-optimal asymptotic methods. A further result gives a sufficient but not necessary condition for speed-optimality among asymptotic methods. Some consequences and open questions are then discussed. (shrink)

In the early 20th century, the most numerous and well-funded institutions in the United States—corporations—used public relations to make a widespread and fundamental change in the way they constitute and regulate their relations of knowledge with the public. Today, we can see this change reflected in a variety of areas such as journalism, political outreach, social media, and in the ‘fake news’ and ‘post-truth’ administration of Donald J. Trump. This article traces practices of corporate truth-telling and knowledge production across three (...) periods I will call the personal, the legal, and public relations, which are roughly coincident with the antebellum period, the Gilded Age, and the 20th century, respectively. In sum, what can be found in public relations and now broadly across society, is that relations of knowledge have come to be refigured as relations of power, subordinating traditional epistemological concerns like justification and belief in favor of government and control.

The number of discriminable colours is often assumed to be of the order of several million but the extent of detectable chromatic diversity present in individual natural scenes is an open question. Here, the aim was to estimate the number of discriminable colours seen in natural scenes. Hyperspectral data were obtained from a set of natural scenes over the range 400 - 720 nm at 10 nm intervals (Nascimento et al, 2002 Journal of the Optical Society of America A 19 (...) 1484 - 1490) and the representation of each scene in CIELAB space computed for all pixels of the image. The number of discriminable colours was estimated by counting the number of unit volumes in the three-dimensional volume defined by the scene when represented in CIELAB space. We found that the number of discriminable colours estimated in a scene could vary by an order of magnitude from scene to scene, but rarely exceeded 105, indicating a limited chromatic diversity.

"This volume offers a new translation of the Neoplatonist philosopher Simplicius' commentary on the chapters concerning place and time in Aristotle's Physics, Book Four. Written after the closing of the Athenian Neoplatonist school in A.D. 529, the commentary clarifies the structure and meaning of Aristotle's arguments and provides a rich account of 800 years of interpretation." "Surprisingly, in the first five chapters of Book Four Aristotle shows place as two-dimensional: one's place is the two-dimensional inner surface of one's surroundings. He (...) also suggests that the upward motion of air and fire and the downward motion of earth and water are partly explained by the natural places to which they tend. Place thus has power (dunamis) of its own. In his last five chapters, Aristotle argues that if time did not entail change its passage would be undetectable, and that time, by definition countable, requires the existence of conscious beings to do the counting. Among the many relevant views that Simplicius records are those of Galen, who attacks this claim, and of Eudemus, who rebuts the Pythagorean theory that history will repeat itself exactly. J. O. Urmson's translation serves as a companion to his earlier translation of the Corollaries on Place and Time, in which Simplicius sets forth his own views as distinct from those of Aristotle."

All humans have an equal basic moral status. They possess the same fundamental rights, and the comparable interests of each person should count the same in calculations that determine social policy. Neither supposed racial differences, nor skin color, sex, sexual orientation, ethnicity, intelligence, nor any other differences among humans negate their fundamental equal worth and dignity. These platitudes are virtually universally affirmed. A white supremacist racist or an admirer of Adolf Hitler who denies them is rightly regarded as beyond the (...) pale of civilized dialogue. However, a very simple line of argument developed by Peter Singer challenges our understanding of these platitudes and forces us to rethink the basis and nature of the moral equality of all humans. What I call the “Singer Problem” arises if one accepts that the morally significant cognitive capacities that are relevant to the determination of the fundamental moral status of a being vary from individual to individual by degree. The problem is to specify a moral principle determining fundamental moral status that assigns a superior status to humans compared to other animals on the basis of the superior cognitive capacities of humans but also assigns all human persons an equal fundamental moral status regardless of their differing cognitive capacities. More broadly posed, the problem is to specify moral principles that yield intuitively satisfactory implications for the treatment of human individuals and other individual animals given that cognitive capacities differ across species and individuals. A search for a resolution of the Singer problem leads to disappointing results. (shrink)

According to one prominent view of exercising abilities (e.g., Millar 2009), a subject, S, counts as exercising an ability to ϕ if and only if S successfully ϕs.

Pascal Engel (2008) has insisted that a number of notable strategies for rejecting the knowledge norm of assertion are put forward on the basis of the wrong kinds of reasons. A central aim of this paper will be to establish the contrast point: I argue that one very familiar strategy for defending the knowledge norm of assertion—viz., that it is claimed to do better in various respects than its competitors (e.g. the justification and the truth norms)— relies on a presupposition (...) that is shown to be ultimately under motivated. That presupposition is the uniqueness thesis—that there is a unique epistemic rule for assertion, and that such a rule will govern assertions uniformly. In particular, the strategy I shall take here will be to challenge the sufficiency leg of the knowledge norm in a way that at the same time counts against Williamson’s (2000) own rationale for the uniqueness thesis. However, rather than to challenge the sufficiency leg of the knowledge norm via the familiar style of ‘expert opinion’ and, more generally, ‘second-hand knowledge’ cases (e.g. Lackey (2008)), a strategy that has recently been called into question by Benton (2014), I’ll instead advance a very different line of argument against the sufficiency thesis, one which turns on a phenomenon I call epistemic hypocrisy.

How do people understand the concepts of mental health and disorder? The objective of this paper is to examine the impact of several factors on people’s judgments about whether a condition constitutes a mental disorder or a healthy state. Specifically, this study examines the impact of the source of the condition, its outcome, individual valuation (i.e., the value the individual attaches to the condition), and group valuation (i.e., the value the relevant group attaches to the condition). While we find that (...) people’s health and disorder judgments are driven by perceived dysfunction, we also find that health and disorder judgments are impacted differently by these factors. Health judgements are impacted by outcome and individual valuation, and disorder judgments are impacted by condition source. These results suggest that the folk concept of mental health is positive (i.e., mental health is more than the absence of mental disorder) and normativist (i.e., value judgments play a significant role in determining whether a condition counts as healthy), while the concept of mental disorder aligns with a naturalist perspective, at least to the extent that dysfunction plays an important role in categorizing a condition as a disorder. However, our finding that people’s dysfunction judgments are influenced by individual valuation and outcomes poses a strong challenge to naturalist accounts. To provide access to our supplementary data, an appendix has been included. (shrink)

What considerations place genuine constraints on an adequate semantics for normative and evaluative expressions? Linguists recognize facts about ordinary uses of such expressions and competent speakers’ judgments about which uses are appropriate. The contemporary literature reflects the widespread assumption that linguists don’t rely upon an additional source of data—competent speakers’ judgments about possible disagreement with hypothetical speech communities. We have several good reasons to think that such judgments are not probative for semantic theorizing. Therefore, we should accord these judgments no (...) probative value for the development of a semantics for our moral terms. Such judgments can no longer be presumed to put pressure on theories according to which our moral expressions share a semantics with ordinary, descriptive terms. Many rivals to pure, Descriptivist theories count among their advantages the ability to accommodate these judgments. If these judgments have no probative value, such theories lose an important source of support. (shrink)

Context: Strict finitism is usually not taken seriously as a possible view on what mathematics is and how it functions. This is due mainly to unfamiliarity with the topic. Problem: First, it is necessary to present a “decent” history of strict finitism (which is now lacking) and, secondly, to show that common counterarguments against strict finitism can be properly addressed and refuted. Method: For the historical part, the historical material is situated in a broader context, and for the argumentative part, (...) an evaluation of arguments and counterarguments is presented. Results: The main result is that strict finitism is indeed a viable option, next to other constructive approaches, in (the foundations of) mathematics. Implications: Arguing for strict finitism is more complex than is usually thought. For future research, strict finitist mathematics itself needs to be written out in more detail to increase its credibility. In as far as strict finitism is a viable option, it will change our views on such “classics” as the platonist-constructivist discussion, the discovery-construction debate and the mysterious applicability problem (why is mathematics so successful in its applications?). Constructivist content: Strict finitism starts from the idea that counting is an act of labeling, hence the mathematician is an active subject right from the start. It differs from other constructivist views in that the finite limitations of the human subject are taken into account. (shrink)

This is a collection of papers, all but one of which were previously published, by one of England's leading logicians. Goodstein has described his position in the philosophy of mathematics as that of a "constructive formalist": leaning toward the Hilbert school, but emphasizing the constructive nature of mathematical entities. The papers are more or less technical and symbolic; those most difficult are "The Nature of Mathematics," "The Decision Problem," and "The Definition of Number." Other titles are "Proof by Reductio ad (...) Absurdum," "Logic Paradoxes", "Language and Experience," "The Meaning of Counting," "Mathematical Systems," "The Axiomatic Method," "Pure and Applied Mathematics," and "The Significance of Incompleteness Theorems"; the last-mentioned paper is also quite difficult, but it constitutes not only one of the best semi-formal presentations of Gödel's theorems, but also helps make quite clear what their relevance is to considerations of the expressive power of formal languages in general. This collection constitutes a fine introduction to the philosophy of mathematics.—P. J. M. (shrink)

The objectively best language is intended to refer to some metaphysically privileged language that ‘carves reality at its joints’ perfectly. That is, it is the kind of language that various ‘metaphysical deflationists’ have argued is impossible. One common line of argument amongst deflationists is that we have no means to compare languages that all express true facts about the world in such a way to decide which is ‘better’. For example, the language is physics is not objectively better than the (...) language of economics, as each language has the semantic purpose of expressing some domain of truths about the world inexpressible in the other language, and therefore neither could be ‘objectively best’. In this paper, I argue that metaphysical deflationists have failed to recognise a distinction between fine- and coarse-grained semantic purposes of languages, and that a recognition of that distinction provides us grounds to compare languages to see which is objectively best. I argue that once we recognise the distinction between fine- and coarse-grained semantic purposes, then we can see that it is relative to the coarse-grained purpose that we must compare putative objectively best ontological languages.
