© 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)

Network neuroscience represents the brain as a collection of regions and inter-regional connections. Given its ability to formalize systems-level models, network neuroscience has generated unique explanations of neural function and behavior. The mechanistic status of these explanations and how they can contribute to and fit within the field of neuroscience as a whole has received careful treatment from philosophers. However, these philosophical contributions have not yet reached many neuroscientists. Here we complement formal philosophical efforts by providing an applied perspective from (...) and for neuroscientists. We discuss the mechanistic status of the explanations offered by network neuroscience and how they contribute to, enhance, and interdigitate with other types of explanations in neuroscience. In doing so, we rely on philosophical work concerning the role of causality, scale, and mechanisms in scientific explanations. In particular, we make the distinction between an explanation and the evidence supporting that explanation, and we argue for a scale-free nature of mechanistic explanations. In the course of these discussions, we hope to provide a useful applied framework in which network neuroscience explanations can be exercised across scales and combined with other fields of neuroscience to gain deeper insights into the brain and behavior.

A bold argument that constitutional states are not weaker because their powers are divided -- they are often stronger because they solve collective action problems rooted in speech and communication.

The Australian HREC system is now highly centralised and subject to national guidelines in an attempt to assure consistency of decision-making and of ethical standards. The penalty has been greatly increased paperwork and reporting requirements which many committees feel burdensome. In addition, many Committees may be under-resourced. However, I argue that though it is timely to reassess the current directions it is an exaggeration to claim that the system is in danger of collapse.

Many researchers have suggested that premise interpretation errors can account, at least in part, for errors on categorical syllogisms. However, although it is possible to show that people make such errors in simple inference tasks, the evidence for them is far less clear when actual syllogisms are administered. Part of the problem is due to the lack of clear predictions for the solutions that would be expected when using modified quantifiers, assuming that correct inferences are made from them. This paper (...) presents the expected solutions for Gricean, reversible, and reversible Gricean interpretations, and evaluates these using three datasets (two currently available, and one new). The evidence supported the adoption of reversible and reversible Gricean interpretations, but not Gricean interpretations on their own. These results suggest that the categorical syllogism task tends to induce different quantifier interpretations from those identified in simple inference tasks. (shrink)

A wide range of biological processes, in all eukaryotes and in some prokaryotes, are controlled by rhythms with a period close to 24 hours. The circadian oscillator, which is responsible for generating these rhythms, is controlled by light signals that maintain its synchrony with the environmental day/night cycle. Higher plants exhibit many circadian rhythms, including rhythms in the transcription of specific genes. Molecular tools derived from such clock‐controlled genes have led to the identification of several circadian rhythm mutants in the (...) genetic model, Arabidopsis thaliana. The extensive understanding of photoperception in this species will make it a powerful system with which to investigate the light regulation of circadian rhythms. We compare Arabidopsis rhythms to the results from other systems, and discuss these data with respect to the current phototransduction models. (shrink)

We are in a state of impending crisis. And the fault lies in part with academia. For two centuries or so, academia has been devoted to the pursuit of knowledge and technological know-how. This has enormously increased our power to act which has, in turn, brought us both all the great benefits of the modern world and the crises we now face. Modern science and technology have made possible modern industry and agriculture, the explosive growth of the world’s population, global (...) warming, modern armaments and the lethal character of modern warfare, destruction of natural habitats and rapid extinction of species, immense inequalities of wealth and power across the globe, pollution of earth, sea and air, even the aids epidemic (aids being spread by modern travel). All these global problems have arisen because some of us have acquired unprecedented powers to act, via science and technology, without also acquiring the capacity to act wisely. (shrink)

Consumers do not always follow their ideological beliefs about the need to engage in environmentally friendly consumption. We propose that Commitment to Beliefs —the general tendency to follow one’s value-based beliefs—can help identify who is most likely to follow their environmental ideologies. We predicted that CTB would amplify the effect of beliefs prescribing environmental stewardship, or neglect, on corresponding intentions, behavior, and purchasing decisions. In two studies, CTB amplified the positive and negative effects of relevant EF ideologies on EF purchase (...) decisions, and consumption and conservation attitudes, intentions, as well as future behavior. In each study, only people with higher levels of CTB demonstrated the most ideologically consistent consumption and conservation intentions and behavior. These findings clarify who is most likely to align their decisions and lifestyles according to their sustainable consumption ideologies. The amplification effect of CTB, and the CTB variable itself, present new contributions to consumer behavior research and the domains of sustainable or ethical consumption in particular and offer wide-ranging potential for marketing practitioners and researchers.

Sensorimotor enactivism takes perceptual experience to be constituted by a kind of attunement to sensorimotor contingencies – law‐like relations between sensory inputs and bodily activity. The chemical senses have traditionally been construed as especially simple and passive, and a number of philosophers have argued that flavour and smell are problem cases for the sensorimotor approach. In this article, I respond to these objections to the sensorimotor approach, and in doing so offer the beginnings of a sensorimotor account of the chemical (...) senses. (shrink)

Largely thanks to Mill’s influence, the suggestion that the state ought to restrict the distribution of misinformation will strike most philosophers as implausible. Two of Mill’s influential assumptions are particularly relevant here: first, that free speech debates should focus on moral considerations such as the harm that certain forms of expression might cause; second, that false information causes minimal harm due to the fact that human beings are psychologically well equipped to distinguish truth and falsehood. However, in addition to our (...) moral obligations, we also have a distinct set of epistemic obligations—and even when a false belief doesn’t harm anyone, it constitutes an epistemically bad outcome. Moreover, Mill was profoundly mistaken about human psychology: human beings are vulnerable to the influence of a wide variety of false claims via a wide variety of psychological mechanisms. Consequently, there is a purely epistemic justification for restricting the distribution of misinformation: because each of us has an individual epistemic obligation to avoid unnecessary exposure to misinformation, and because avoiding such exposure is simply too difficult when acting alone, we all have a shared epistemic obligation to establish laws or regulations restricting the widespread distribution of misinformation.

We need urgently to bring about a revolution in universities around the world, wherever possible, so that they take their fundamental task to be, not to acquire and apply knowledge, but rather to help humanity learn how to resolve conflicts and problems of living in increasingly cooperatively rational ways, so that we may make progress towards a good, genuinely civilized, wise world. The pursuit of knowledge would be a vital but subsidiary task. I have argued for the urgent need for (...) such an academic revolution for nearly 50 years, ever since the publication of two books: What’s Wrong With Science? Towards a People’s Rational Science of Delight and Compassion, 1976, and From Knowledge to Wisdom: A Revolution for Science and the Humanities, 1984, both available free online. This article, written in preparation for a talk given to Pittsburgh University on the 15th September 2023, gives an outline of my baffled struggles with problems of philosophy, science, literature and life that led up to the discovery of the urgent need for an intellectual and institutional revolution in universities around the world, needed in order to galvanize the social revolution required to enable us to make progress to a world in which peace, justice, democracy, individual freedom, sustainable prosperity, the possibility of a good life, are available to all, insofar as that is attainable.

Philosophical research into olfaction often focuses on its limitations. We explore instead an underappreciated capacity of the sense of smell, namely, its role in interpersonal experience. To illustrate this, we examine how smell can enable continuing connections to deceased loved ones. Understanding this phenomenon requires an appreciation of, first, how olfaction's limitations can facilitate experiences of the deceased person and, second, how olfaction enables experiences of what we refer to as the ‘olfactory air’ of a person. This way of experiencing (...) someone privileges their status as an environmentally situated human animal. (shrink)

Objects are central to perception and our interactions with the world. We perceive the world as parsed into discrete entities that instantiate particular properties, and these items capture our attention and shape how we interact with the environment. Recently there has been some debate about whether the sense of smell allows us to perceive odours as discrete objects, with some suggesting that olfaction is aspatial and doesn’t allow for object-individuation. This paper offers two empirically tractable criteria for assessing whether particular (...) objects are exhibited in perceptual experience— susceptibility to figure-ground segregation and perceptual constancies—and argues that these criteria are fulfilled by olfactory perception, and thus there are olfactory objects. I argue that there are, in fact, two different ways that olfaction allows for figure-ground segregation. First, I look at various Gestalt grouping principles, which are thought to govern when features are perceived as grouped into structured wholes, segregated from everything around them. I argue that these principles apply to olfactory experience, providing evidence of non-spatial figure-ground segregation. Second, I defend the contentious idea that a spatial variety of figure-ground segregation can also occur in olfaction. To see this, however, we need to look to empirical evidence showing that tactile stimulation and bodily movements play a crucial role in olfactory phenomenology. Finally, I draw on empirical evidence and olfactory phenomenology to argue that there are perceptual constancies in olfactory experience, allowing us to perceive odours as coherent objects that survive shifts in our perspectives on the world.

Gómez Pereira's Antoniana Margarita (1554) represents one of the most original works of his time. Its author develops some issues of great impact in later philosophy, such as animal automatism, soul-body radical separation and self-awareness.

Mentoring Away the Glass Ceiling in Academia: A Cultured Critique describes how women of diverse backgrounds perceive their mentoring experiences or the lack of mentoring experiences in the academy.

The story of Naboth’s vineyard (1 Kings 21:1-16) is one played out during the dynasty of Omri in Northern Israel (866-842 BCE) and speaks to an era in which socio-economics were largely dominated by political elites. The narrative concerns inter alia a clash between two arrangements of land ownership, inheritance and possession by others. Thus, from a socio – analytical perspective, the story has lessons to impart to 2022 South Africa where the issue of the land redistribution is an important (...) one given that even after a quarter of a century post-apartheid, millions of people continue to have no real access to land. Many people are thus left precariously exposed and vulnerable. The story imparts the truth that a leader of a state is bound to respect the proprietary rights of his citizens. In any event, viewed from a theological perspective, all the resources of creation are to be utilised to serve the common good and we are all custodians of creation. This includes people who have no private property of their own and who are for the most part excluded and side-lined by those in positions of power. The story of Naboth’s vineyard is thus a simple one where a sovereign sees something he wants, and then formulates a strategy to get it. In Naboth’s story, the king had him killed. This is a very constructive rendition of what happens when there’s no justice and the dominant powers get to terminate those who stand in their way. Justice tends to break down when people lose perspective of who they are concerning God who ultimately forgives us when we atone. (shrink)

Healthcare workers carry a substantial risk of harm from infectious disease, particularly, but not exclusively, during outbreaks. More can be done by healthcare institutions to identify risks, quantify the current burden of preventable infectious disease amongst HCWs and identify opportunities for prevention. We suggest that institutional obligations should be clarified with respect to the mitigation of infectious disease risks to staff, and question the duty of HCWs to care while healthcare institutions persist with a reactive rather than proactive attitude to (...) infectious disease threats.

Alan Miller offers a focused account of perceptual knowledge, the knowledge that we gain by means of seeing, hearing, feeling, smelling, and tasting. He explains perceptual knowledge in terms of general recognitional abilities, then situates that account within a broader perspective on epistemology and philosophical method more generally.

The fact that each of us has significantly greater confidence in the claims of co-partisans – those belonging to groups with which we identify – explains, in large part, why so many people believe a significant amount of the misinformation they encounter. It's natural to assume that such misinformed partisan beliefs typically involve a rational failure of some kind, and philosophers and psychologists have defended various accounts of the nature of the rational failure purportedly involved. I argue that none of (...) the standard diagnoses of the irrationality of misinformed partisan beliefs is convincing, but I also argue that we ought to reject attempts to characterize these beliefs as rational or consistent with epistemic virtue. Accordingly, I defend an alternative diagnosis of the relevant epistemic error. Specifically, I maintain that such beliefs typically result when an individual evaluating testimony assigns more weight to co-partisanship than he ought to under the circumstances, and consequently believes the testimony of co-partisans when better alternatives are available.

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you are prevented from perceiving (...) properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected.

This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as _computational phenomenology_ because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy (e.g., the work of Edmund Husserl, Maurice Merleau-Ponty, etc.). The first section presents a brief review of the overall project to naturalize phenomenology. The second section presents and evaluates (...) philosophical objections to that project and situates our version of computational phenomenology with respect to these projects. The third section reviews the generative modelling framework. The final section presents our approach in detail. We conclude by discussing how our approach differs from previous attempts to use generative modelling to help understand consciousness. In summary, we describe a version of computational phenomenology which uses generative modelling to construct a computational model of the inferential or interpretive processes that best explain this or that kind of lived experience.

It is widely acknowledged that individual moral obligations and responsibility entail shared (or joint) moral obligations and responsibility. However, whether individual epistemic obligations and responsibility entail shared epistemic obligations and responsibility is rarely discussed. Instead, most discussions of doxastic responsibility focus on individuals considered in isolation. In contrast to this standard approach, I maintain that focusing exclusively on individuals in isolation leads to a profoundly incomplete picture of what we're epistemically obligated to do and when we deserve epistemic blame. First, (...) I argue that we have epistemic obligations to perform actions of the sort that can be performed in conjunction with other people, and that consequently, we are often jointly blameworthy when we violate shared epistemic obligations. Second, I argue that shared responsibility is especially important to doxastic responsibility thanks to the fact that we don't have the same kind of direct control over our beliefs that we have over our actions. In particular, I argue that there are many cases in which a particular individual who holds some problematic belief only deserves epistemic blame in virtue of belonging to a group all the members of which are jointly blameworthy for violating some shared epistemic obligation.

Birds, beasts, and creeping things swarm throughout the Bible's pages. Despite their prevalence, most biblical scholars have viewed them merely as metaphors, passive objects, or background embellishment to the human experience. This collection seeks to move beyond this traditional view of biblical animals by engaging the growing interdisciplinary field of animal studies. Contributors Peter Joshua Atkins, Jared Beverly, William P. Brown, Margaret Cohen, Jacob R. Evers, Michael J. Gilmour, William "Chip" Gruen, Dong Hyeon Jeong, Brian Fiu Kolia, Anne Létourneau, Robert (...) R. MacKay, Suzanna R. Millar, Timothy J. Sandoval, Robert Paul Seesengood, Ken Stone, Brian James Tipton, Arthur W. Walker-Jones, and Jaime L. Waters showcase the breadth and depth of inquiry that animal studies can foster in biblical studies as well as what animal studies can gain from a more rigorous engagement with biblical texts. Together the essays offer an animal hermeneutic that supports the flourishing of all creatures. (shrink)

© Millar 2018This bold, provocative, and highly original book is in three Parts. Part I outlines a problem, sketches a solution, and defends a claim that is crucial to the solution—that ‘perceptual experiences and the processes by which they arise can be rational or irrational’. This claim is The Rationality of Perception. In Part II Siegel argues that the power of experiences to justify beliefs can be downgraded or upgraded by psychological precursors. Part III applies, and further develops, the (...) theoretical framework that has been outlined in the previous parts. The topics addressed there include fearful and wishful seeing, and selection effects as they bear on the character of experiences. The last chapter concerns the appraisal of culturally appropriated racial attitudes that can influence beliefs and, on Siegel’s view, visual experiences as well. The discussion throughout takes readers well off the beaten track and is to... (shrink)

This book argues for the need to put into practice a profound and comprehensive intellectual revolution, affecting to a greater or lesser extent all branches of scientific and technological research, scholarship and education. This intellectual revolution differs, however, from the now familiar kind of scientific revolution described by Kuhn. It does not primarily involve a radical change in what we take to be knowledge about some aspect of the world, a change of paradigm. Rather it involves a radical change in (...) the fundamental, overall intellectual aims and methods of inquiry. At present inquiry is devoted to the enhancement of knowledge. This needs to be transformed into a kind of rational inquiry having as its basic aim to enhance personal and social wisdom. This new kind of inquiry gives intellectual priority to the personal and social problems we encounter in our lives as we strive to realize what is desirable and of value – problems of knowledge and technology being intellectually subordinate and secondary. For this new kind of inquiry, it is what we do and what we are that ultimately matters: our knowledge is but an aspect of our life and being. (shrink)

Thanks to the advent of social media, large numbers of Americans believe outlandish falsehoods that have been widely debunked. Many of us have a tendency to fault the individuals who hold such beliefs. We naturally assume that the individuals who form and maintain such beliefs do so in virtue of having violated some epistemic obligation: perhaps they failed to scrutinize their sources, or failed to seek out the available competing evidence. I maintain that very many ordinary individuals who acquire outlandish (...) false beliefs thanks to their use of popular social media platforms (and other similar internet technologies) deserve little or no blame for believing these falsehoods. Such individuals would be fully blameworthy only if they had formed or maintained the relevant beliefs partly in virtue of violating some epistemic obligation and had no excuse for violating that obligation. However, the nature of these internet technologies provides excuses for violating the relevant epistemic obligations, and so individuals are excused for holding the resulting false beliefs. (shrink)

How can the world we live in and see, touch, hear, and smell, the world of living things, people, consciousness, free will, meaning, and value - how can all of this exist and flourish embedded as it is in the physical universe, made up of nothing but physical entities such as electrons and quarks? How can anything be of value if everything in the universe is, ultimately, just physics? In Our Fundamental Problem Nicholas Maxwell argues that this problem of (...) reconciling the human and physical worlds needs to take centre stage in our thinking, so that our best ideas about it interact with our attempts to solve even more important specialized problems of thought and life. When we explore this fundamental problem, Maxwell argues, revolutionary answers emerge for a wide range of questions arising in philosophy, science, social inquiry, academic inquiry as a whole, and - most important of all - our capacity to solve the global problems that threaten our future: climate change, habitat destruction, extinction of species, inequality, war, pollution of earth, sea, and air. An unorthodox introduction to philosophy, Our Fundamental Problem brings philosophy down to earth and demonstrates its vital importance for science, scholarship, education, life, and the fate of the world.

The Comprehensibility of the Universe puts forward a radically new conception of science. According to the orthodox conception, scientific theories are accepted and rejected impartially with respect to evidence, no permanent assumption being made about the world independently of the evidence. Nicholas Maxwell argues that this orthodox view is untenable. He urges that in its place a new orthodoxy is needed, which sees science as making a hierarchy of metaphysical assumptions about the comprehensibility and knowability of the universe, these (...) assumptions asserting less and less as one ascends the hierarchy. This view has significant implications: that it is part of scientific knowledge that the universe is physically comprehensible; that metaphysics and philosophy are central to scientific knowledge; that science possesses a rational, if fallible, method of discovery; that a new understanding of scientific method and rationality is required. Maxwell argues that this new conception makes possible a natural resolution of long-standing philosophical problems about science, regarding simplicity, induction, and progress. His goal is the reform not just of the philosophy of science but of science itself, and the healing of the rift between the two. (shrink)

This paper argues that philosophers of science have before them an important new task that they urgently need to take up. It is to convince the scientific community to adopt and implement a new philosophy of science that does better justice to the deeply problematic basic intellectual aims of science than that which we have at present. Problematic aims evolve with evolving knowledge, that part of philosophy of science concerned with aims and methods thus becoming an integral part of science (...) itself. The outcome of putting this new philosophy into scientific practice would be a new kind of science, both more intellectually rigorous and one that does better justice to the best interests of humanity.
