© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

One controversy about the existence of so called evolutionary forces such as natural selection and random genetic drift concerns the sense in which such “forces” can be said to interact. In this paper I explain how natural selection and random drift can interact. In particular, I show how population-level probabilities can be derived from individual-level probabilities, and explain the sense in which natural selection and drift are embodied in these population-level probabilities. I argue that whatever causal character the individual-level probabilities (...) have is then shared by the population-level probabilities, and that natural selection and random drift then have that same causal character. Moreover, natural selection and drift can then be viewed as two aspects of probability distributions over frequencies in populations of organisms. My characterization of population-level probabilities is largely neutral about what interpretation of probability is required, allowing my approach to support various positions on biological probabilities, including those which give biological probabilities one or another sort of causal character. ‡This paper has benefited from feedback on and discussions of this and earlier work.

Marshall and colleagues (2024) bring to broader academic and public attention a genuine and difficult dilemma to which emergency physicians are confronted with. The dilemma could be summarized as:r...

Professor Sutton opens his lively monograph on the nature of economic theory with the following question: is it possible to find economic models that work? He uses the question to guide us on a methodological tour with Marshall's characterization of economic theory as the point of departure. I must say I enjoyed the trip. Along the way, the animating issue of what works in economics could hardly have been addressed without dealing with issues in verification, and the author's arguments (...) include an appraisal of what he considers as standard econometric methods. In these comments, I will revisit at some length one of the key sites on John Sutton's tour bringing along a view of modern econometrics which is somewhat different from his and which affords a different perspective on the Marshallian paradigm.

The main point of this paper is to contribute to understanding Milton Friedman’s (1953) “The Methodology of Positive Economics” (hereafter F1953), one of the most influential statements of economic methodology of the twentieth century, and, in doing so, help discern the non trivial but complex role of philosophic ideas in the shaping of economic theorizing and economists’ self-conception. It also aims to contribute to a better understanding of the theoretical origins of the so-called ‘Chicago’ school of economics. In this paper, (...) I first present detailed textual evidence of the familiarity of George Stigler with the early work of Talcott Parsons, the most important American translator and disseminator of Max Weber’s ideas, who also helped create sociology as a distinct discipline in the United States. The Chicago-Parsons link is no surprise because historians have known that Frank Knight and Parsons corresponded, first about translating Weber and then about matters of mutual interest. Knight, who was a doctoral advisor to Stigler and teacher of Milton Friedman, was not merely the first American translator of Weber, but remained keenly and, perhaps, increasingly interested in Weber throughout his life. I am unfamiliar with any investigation of the Weberian influence on Knight’s students. I show that Stigler praises Parsons’ treatment of Alfred Marshall, who plays an outsized role in Friedman’s self-conception of economics and economic theory. I also show that Stigler calls attention to the methodological similarity between Friedman and Parsons. Finally, I turn to F1953, and I show, first, that some of its most distinctive and philosophically interesting claims echo Parsons’ treatment of methodological matters; second that once alerted one can note Weberian terminology in F1953.

> Wealthy nations must do much more, much faster. The United Nations General Assembly in September 2021 will bring countries together at a critical time for marshalling collective action to tackle the global environmental crisis. They will meet again at the biodiversity summit in Kunming, China, and the climate conference 26) in Glasgow, UK. Ahead of these pivotal meetings, we—the editors of health journals worldwide—call for urgent action to keep average global temperature increases below 1.5°C, halt the destruction of nature (...) and protect health. Health is already being harmed by global temperature increases and the destruction of the natural world, a state of affairs health professionals have been bringing attention to for decades.1 The science is unequivocal; a global increase of 1.5°C above the preindustrial average and the continued loss of biodiversity risk catastrophic harm to health that will be impossible to reverse.2 3 Despite the world’s necessary preoccupation with COVID-19, we cannot wait for the pandemic to pass to rapidly reduce emissions. Reflecting the severity of the moment, this editorial appears in health journals across the world. We are united in recognising that only fundamental and equitable changes to societies will reverse our current trajectory. The risks to health of increases above 1.5°C are now well established.2 Indeed, no temperature rise is ‘safe’. In the past 20 years, heat-related mortality among people aged over 65 has increased by more than 50%.4 Higher temperatures have brought increased dehydration and renal function loss, dermatological malignancies, tropical infections, adverse mental health outcomes, pregnancy complications, allergies, and cardiovascular and pulmonary morbidity and mortality.5 6 Harms disproportionately affect the most vulnerable, including children, older populations, ethnic minorities, poorer communities and those with underlying health problems.2 4 Global heating is also contributing to the decline in ….

Schopenhauer repeatedly claims that suicide is both foolish and futile. But while many commentators have expressed sympathy for his charge of foolishness, most regard his charge of futility as indefensible even within his own system. In this paper, I offer a defense of Schopenhauer’s futility charge, based on metaphysical and psychological considerations. On the metaphysical front, Schopenhauer’s view implies that psychological connections extend beyond death. Drawing on Parfit’s discussion of personal identity, I argue that those connections have personal significance, such (...) that suicide does not allow one, as Hamlet hopes, simply “not to be.” On the psychological front, I argue that a distinction between agents’ intentions and underlying desires makes room for Schopenhauer to claim that paradigmatic suicidal agents ultimately desire the opposite of what suicide accomplishes. I conclude by showing how the resulting account of futility can buttress the charge of foolishness as well. My interpretation still leaves Schopenhauer vulnerable to certain objections, but shows that his account is significantly more defensible than previous commentators have realized. (shrink)

Consider the following three claims. (i) There are no truths of the form ‘p and ~p’. (ii) No one holds a belief of the form ‘p and ~p’. (iii) No one holds any pairs of beliefs of the form {p, ~p}. Irad Kimhi has recently argued, in effect, that each of these claims holds and holds with metaphysical necessity. Furthermore, he maintains that they are ultimately not distinct claims at all, but the same claim formulated in different ways. I find (...) his argument suggestive, if not entirely transparent. I do think there is at least an important kernel of truth even in (iii), and that (i) ultimately explains what’s right about the other two. Consciousness of an impossibility makes belief in the obtaining of the corresponding state of affairs an impossibility. Interestingly, an appreciation of this fact brings into view a novel conception of inference, according to which it consists in the consciousness of necessity. This essay outlines and defends this position. A central element of the defense is that it reveals how reasoners satisfy what Paul Boghossian calls the Taking Condition and do so without engendering regress. (shrink)

Concepts: Core Readings traces the develoment of one of the most active areas of investigation in cognitive science. This comprehensive volume brings together the essential background readings on concepts from philosophy, psychology, and linguistics, while providing a broad sampling of contemporary research. The first part of the book centers around the fall of the Classical Theory of Concepts in the face of attacks by W.V.O. Quine, Ludwig Wittgenstein, Eleanor Rosch, and others, emphasizing the emergence and development of the Prototype Theory (...) and the controversies it spurred. The second part surveys a broad range of contemporary theories—Neoclassical Theories, the Prototype Theory, the Theory-Theory, and Conceptual Atomism. (shrink)

Rationalization, in our intended sense of the term, occurs when a person favors a particular conclusion as a result of some factor (such as self-interest) that is of little justificatory epistemic relevance, if that factor then biases the person’s subsequent search for, and assessment of, potential justifications for the conclusion. Empirical evidence suggests that rationalization is common in people’s moral and philosophical thought. We argue that it is likely that the moral and philosophical thought of philosophers and moral psychologists is (...) also pervaded by rationalization. Moreover, although rationalization has some benefits, overall it would be epistemically better if the moral and philosophical reasoning of people, including professional academics, were not as heavily influenced by rationalization as it likely is. We discuss the significance of our arguments for cognitive management and epistemic responsibility. (shrink)

I argue that to have an attitude is, primarily, (1.) to have a dispositional profile that matches, to an appropriate degree and in appropriate respects, a stereotype for that attitude, typically grounded in folk psychology, and secondarily, (2.) in some cases also to meet further stereotypical attitude-specific conditions. To have an attitude, on the account I will recommend here, is mainly a matter of being apt to interact with the world in patterns that ordinary people would regard as characteristic of (...) having that attitude. I contrast this view with alternative views that treat having an attitude as a matter of possessing some particular internally stored representational content or some other "deep" structural feature.

In this acclaimed exploration of the search for "authentic" individual identity, Marshall Berman explores the historical experiences and needs out of which this new radicalism arose. Focussing on eighteenth-century Paris, a time and place in which a distinctively modern form of society was just coming into its own, Berman shows how the ideal of authenticity—of a self that could organize the individual's energy and direct it toward his own happiness—articulated eighteenth-century man's deepest responses to this brave new world, and (...) his most ardent hope for a new life in it. Exploring in particular the ideas of Montesquieu and Rousseau, Berman shows how the ideal of authenticity was radically opposed to the bourgeois, capitalistic idea of "self-interest.". (shrink)

Considered the most original thinker in the Italian philosophical tradition, Giambattista Vico has been the object of much scholarly attention but little consensus. In this new interpretation, David L. Marshall examines the entirety of Vico's oeuvre and situates him in the political context of early modern Naples. He demonstrates Vico's significance as a theorist who adapted the discipline of rhetoric to modern conditions. Marshall presents Vico's work as an effort to resolve a contradiction. As a professor of rhetoric (...) at the University of Naples, Vico had a deep investment in the explanatory power of classical rhetorical thought, especially that of Aristotle, Cicero, and Quintilian. Yet as a historian of the failure of Naples as a self-determining political community, he had no illusions about the possibility or worth of democratic and republican systems of government in the post-classical world. As Marshall demonstrates, by jettisoning the assumption that rhetoric only illuminates direct, face-to-face interactions between orator and auditor, Vico reinvented rhetoric for a modern world in which the Greek polis and the Roman res publica are no longer paradigmatic for political thought.

We present evidence that mainstream Anglophone philosophy is insular in the sense that participants in this academic tradition tend mostly to cite or interact with other participants in this academic tradition, while having little academic interaction with philosophers writing in other languages. Among our evidence: In a sample of articles from elite Anglophone philosophy journals, 97% of citations are citations of work originally written in English; 96% of members of editorial boards of elite Anglophone philosophy journals are housed in majority-Anglophone (...) countries; and only one of the 100 most-cited recent authors in the Stanford Encyclopedia of Philosophy spent most of his career in non-Anglophone countries writing primarily in a language other than English. In contrast, philosophy articles published in elite Chinese-language and Spanish-language journals cite from a range of linguistic traditions, as do non-English-language articles in a convenience sample of established European-language journals. We also find evidence that work in English has more influence on work in other languages than vice versa and that when non-Anglophone philosophers cite recent work outside of their own linguistic tradition it tends to be work in English.

Unconscious logical inference seems to rely on the syntactic structures of mental representations (Quilty-Dunn & Mandelbaum 2018). Other transitions, such as transitions using iconic representations and associative transitions, are harder to assimilate to syntax-based theories. Here we tackle these difficulties head on in the interest of a fuller taxonomy of mental transitions. Along the way we discuss how icons can be compositional without having constituent structure, and expand and defend the “symmetry condition” on Associationism (the idea that associative links and (...) transitions are perfectly symmetric). In the end, we show how a BIT (“bare inferential transition”) theory can cohabitate with these other non-inferential mental transitions. (shrink)

Philosophers tend to be pretty impressed by human self-knowledge. Descartes (1641/1984) thought our knowledge of our own stream of experience was the secure and indubitable foundation upon which to build our knowledge of the rest of the world. Hume – who was capable of being skeptical about almost anything – said that the only existences we can be certain of are our own sensory and imagistic experiences (1739/1978, p. 212). Perhaps the most prominent writer on self-knowledge in contemporary philosophy is (...) Sydney Shoemaker. The central aim of much of his work has been to show that certain sorts of error are impossible (1963, 1988, 1994). David Chalmers has likewise attempted to show that, for a suitably constrained class of beliefs about one’s own consciousness, error is impossible (2003, sec. 4.1). Even philosophers most of the community thinks of as pessimistic about self-knowledge of consciousness seem to me, really, to be fairly optimistic. Paul Churchland, famous for his disdain of ordinary people’s knowledge about the mind, compares the accuracy of introspection to the accuracy of sense perception – pretty good, presumably, about medium-sized, nearby matters (1985, 1988). Dan Dennett, often cited as a pessimist about introspective report, actually says that we can come close to infallibility when charitably interpreted (2002). The above references concern knowledge of the stream of conscious experience, but philosophers have also tended to be impressed with our self-knowledge of our attitudes, such as our beliefs and desires. Consider this: Although I can be wrong about its being sunny outside, I can’t in the same way be wrong, it seems, about the fact that I think it’s sunny outside. Some.. (shrink)

In On Empirically Equivalent Systems of the World from 1975, Quine formulated a thesis of underdetermination roughly to the effect that every scientific theory has an empirically equivalent but logically incompatible rival, one that cannot be discarded merely as a terminological variant of the former. For Quine, the truth of this thesis was an open question. If true, some would argue that it undermines any belief in scientific theories that is based purely on their empirical success. But despite its potential (...) significance, surprisingly little has been done by way of establishing or refuting it. My aim is to establish the thesis for as large a class of theories as possible. Under various precisifications of the concepts involved, I show that it holds for all consistent and recursively axiomatizable theories that postulate infinitely many theoretical entities. (shrink)

On an intellectualist approach to belief, the intellectual endorsement of a proposition (such as “The working poor deserve as much respect as the handsomely paid”) is sufficient or nearly sufficient for believing it. On a pragmatic approach to belief, intellectual endorsement is not enough. Belief is behaviorally demanding. To really, fully believe, you must also “walk the walk.” This chapter argues that the pragmatic approach is preferable on pragmatic grounds: It rightly directs our attention to what matters most in thinking (...) about belief.

Eric Martin and Daniel N. Osherson present a theory of inductive logic built on model theory.

Can large language models produce expert‐quality philosophical texts? To investigate this, we fine‐tuned GPT‐3 with the works of philosopher Daniel Dennett. To evaluate the model, we asked the real Dennett 10 philosophical questions and then posed the same questions to the language model, collecting four responses for each question without cherry‐picking. Experts on Dennett's work succeeded at distinguishing the Dennett‐generated and machine‐generated answers above chance but substantially short of our expectations. Philosophy blog readers performed similarly to the experts, while ordinary (...) research participants were near chance distinguishing GPT‐3's responses from those of an “actual human philosopher”.

Abstract:With democracy in mind, promoting students’ cognitive, personal, and social development can inform and shape the mathematics curriculum and classroom practice with the goal of their becoming more capable, self-reflective, and socially aware human beings. Toward that realization, their mathematics experience could include: heuristics, as it provides a natural language for problem solving; habits of mind, so students can think and act with a more developed “reflective intelligence”; and multiple-centers investigations, where collaborations based on shared mathematical interest can be pursued. (...) In this way, their education would be “a fostering, a nurturing, a cultivating process” that supports the development of democratic society. (shrink)

Dan Marshall and Josh Parsons note, correctly. that the property of being either a cube or accompanied by a cube is incorrectly classified as intrinsic under the definition we have given unless it turns out to be disjunctive. Whether it is disjunctive, under the definition we gave, turns on certain judgements of the relative naturalness of properties. They doubt the judgements of relative naturalness that would classify their property as disjunctive. We disagree. They also suggest that the whole idea (...) of judging relative naturalness is a dubious business. We reply that, like them or not, such judgements cannot easily be avoided. (shrink)

Kant makes a striking reference to Spinoza in the 1788 Critique of Practical Reason. This chapter begins by investigating whether Kant directly concerned himself with Spinoza, focusing on Omri Boehm's recent affirmative argument. Kant thinks the objective principle yields radical metaphysical conclusions only in conjunction with further claims about specific conditioning relations. Kant's privileging of Spinozism among realist views seems generally detached from Spinoza's actual thought. The chapter deals with points of convergence or near‐convergence between Kant and Spinoza. It identifies (...) two philosophically interesting points on which Spinoza's and Kant's views come surprisingly close: their arguments for the limitations of our sensory knowledge and their arguments for the timelessness of the mind. Spinoza's official argument for the timelessness of the mind appeals to his doctrines of the body's eternal essence, the parallel between bodies and ideas, and the identity of the human mind with God's idea of the human body.

In this book, Eric Havelock presents a challenging account of the development of the idea of justice in early Greece, and particularly of the way justice changed as Greek oral tradition gradually gave way to the written word in a literate society. He begins by examining the educational functions of poets in preliterate Greece, showing how they conserved and transmitted the traditions of society, a thesis adumbrated in his earlier book Preface to Plato. Homer, he demonstrates, has much to (...) say about justice, but since that idea is nowhere in the epics directly stated or expressed, it must be deduced from the speech and actions of the characters. Havelock's careful reading of the Iliad and the Odyssey is original and revealing; it sheds light both on Homeric notions of justice and on the Archaic Greek society depicted in the poems. As Havelock continues his inquiry from Hesiod to Aeschylus, his findings become more complex. The oral Greek world shades into a literate one. Words lose some kinds of meanings, gain others, and steadily become more suited to the conceptualization that Plato strove for and achieved. This evolution of language itself, Havelock shows, was one of the principal accomplishments of the Greek world. Lucidly written and forcefully argued, this book is a major contribution to our knowledge of ancient Greece--its politics, philosophy, and literature, from Homer to Plato. (shrink)

One big question in biology is what life is, but another is how life divides into living things. This is the problem of biological individuality. Proposed statements of the problem have been vague and incomplete. And proposed theories of biological individuality are not detailed enough to solve the problem even if they are correct.

Making these claims explicit will (...) enable us to see better what the problem is and what form a solution to it would need to have. (shrink)

Just as mathematics helps us to represent and reason about the natural world, in its internal applications one branch of mathematics helps us to represent and reason about the subject matter of another. Recognition of the close analogy between internal and external applications of mathematics can help resolve two persistent philosophical puzzles concerning its applicability: a platonist puzzle arising from the abstractness of mathematical objects; and an empiricist puzzle arising from mathematical propositions’ lack of empirical factual content. In order to (...) see how this is the case, we will examine what it is to apply mathematics internally and describe examples. (shrink)
