Aging is accompanied by changes in general cognitive functioning which may impact the learning rate of older adults; however, this is often not controlled for in cognitive aging studies. We investigated the contribution of differences in learning rates to age-related differences in landmark knowledge acquired from route learning. In Experiment 1 we used a standard learning procedure in which participants received a fixed amount of exposure to a route. Consistent with previous research, we found age-related deficits in associative cue and (...) landmark sequence knowledge. Experiment 2 controlled for differences in learning rates by using a flexible exposure learning procedure. Specifically, participants were trained to a performance criterion during route learning before being tested on the content of their route knowledge. While older adults took longer to learn the route than younger adults, the age-related differences in associative cue knowledge were abolished. The deficit in landmark sequence knowledge, however, remained. Experiment 3 replicated these results and introduced a test situation in which a deficit in landmark sequence knowledge yielded an increased likelihood of disorientation in older adults. The findings of this study suggest that age-related deficits in landmark associative cue knowledge are attenuated by controlling for learning rates. In contrast, landmark sequence knowledge deficits persist and are best explained by changes in the learning strategy of older adults to acquire task essential associative cue knowledge at the expense of supplementary sequence knowledge.

This article describes research to build an embodied conversational agent as an interface to a question-and-answer system about a National Science Foundation program. We call this ECA the LifeLike Avatar, and it can interact with its users in spoken natural language to answer general as well as specific questions about specific topics. In an idealized case, the LifeLike Avatar could conceivably provide a user with a level of interaction such that he or she would not be certain as to whether (...) he or she is talking to the actual person via video teleconference. This could be considered a extended version of the seminal Turing test. Although passing such a test is still far off, our work moves the science in that direction. The Uncanny Valley notwithstanding, applications of such lifelike interfaces could include those where specific instructors/caregivers could be represented as stand-ins for the actual person in situations where personal representation is important. Possible areas that come to mind that might benefit from these lifelike ECAs include health-care support for elderly/disabled patients in extended home care, education/training, and knowledge preservation. Another more personal application would be to posthumously preserve elements of the persona of a loved one by family members. We apply this approach to a Q/a system for knowledge preservation and dissemination, where the specific individual who had this knowledge was to retire from the US National Science Foundation. The system is described in detail, and evaluations were performed to determine how well the system was perceived by users. (shrink)

This is the first book to offer the best essays, articles, and speeches on ethics and intelligence that demonstrate the complex moral dilemmas in intelligence collection, analysis, and operations. Some are recently declassified and never before published, and all are written by authors whose backgrounds are as varied as their insights, including Robert M. Gates, former Director of the Central Intelligence Agency; John P. Langan, the Joseph Cardinal Bernardin Professor of Catholic Social Thought at the Kennedy Institute of Ethics, Georgetown (...) University; and Loch K. Johnson, Regents Professor of Political Science at the University of Georgia and recipient of the Owens Award for contributions to the understanding of U.S. intelligence activities. Creating the foundation for the study of ethics and intelligence by filling in the gap between warfare and philosophy, this is a valuable collection of literature for building an ethical code that is not dependent on any specific agency, department, or country.

This paper provides a preliminary account of fallacies on Toulmin’s model of argument, one that improves upon previous attempts to understand fallacies on this argument scheme. To do this Johnson and Blair’s taxonomy of three basic fallacies is examined using Toulmin’s layout.

Philosophers have proposed many accounts of biological function. A coarse-grained distinction can be made between backward-looking views, which emphasise historical contributions to fitness, and forward-looking views, which emphasise the current contribution to fitness or role of a biological component within some larger system. These two views are often framed as being incompatible and conflicting with one another. The emerging field of synthetic biology, which involves applying engineering principles to the design and construction of biological systems, complicates things further by adding (...) intentional design as a source of function. In the current study we explored how biology experts and novices think about function in the context of single-celled, multi-celled, and synthetic organisms. We also explored the extent to which each group were function pluralists, and if they were function pluralists, which accounts of function tended to be endorsed together. The results showed a surprising degree of similarity between experts and novices in most contexts, although certain differences were apparent. Most surprisingly, we found evidence not only of function pluralism in both groups, but pluralism between backward-looking and forward-looking accounts. We discuss these findings in the context of the philosophical debate on function and consider the practical implications for public acceptance of synthetic biology. First, we argue that philosophers of biology should re-examine the purported incompatibility between accounts of function. Second, we argue that due to the introduction of an intentional aetiology in synthetic biology, there may be an inherent conflict between the views of experts and novices when thinking about synthetic biology.

ObjectiveTo present the ethical issues, moral arguments, and reasons found in the ethical literature on organoid models.DesignIn this systematic review of reasons in ethical literature, we selected sources based on predefined criteria: The publication mentions moral reasons or arguments directly relating to the creation and/or use of organoid models in biomedical research; These moral reasons and arguments are significantly addressed, not as mere passing mentions, or comprise a large portion of the body of work; The publication is peer-reviewed and published (...) in an academic article, book, national-level report, working paper, or Ph.D. thesis; The publications collected are in English.AnalysisEach article was read in-depth for identifiable moral reasons, arguments, and concerns. These were then inductively classified and synthesized to create broader categories of reasons, and eventually an overarching conceptual scheme was created.ResultsA total of twenty-three sources were included and analyzed out of an initial 266 collected sources. Five themes of ethical issues and arguments were found: Animal Experimentation; Clinical Applications and Experiments; Commercialization and Consent; Organoid Ontology and Moral Status; and Research Ethics and Research Integrity. These themes are then further broken down into sub-themes and topics. Given the extensive nature of the topics found, we will focus on describing the topics that comprised of more in-depth reasons and arguments rather than few, passing mentions or concerns.ConclusionsThe ethics of organoids requires further deliberation in multiple areas, as much of the discussions are not presented as in-depth arguments. Such sentiments are also echoed throughout the organoid ethics literature. (shrink)

We investigated, experimentally, the contention that the folk view, or naïve theory, of time, amongst the population we investigated is dynamical. We found that amongst that population, ~ 70% have an extant theory of time that is more similar to a dynamical than a non-dynamical theory, and ~ 70% of those who deploy a naïve theory of time deploy a naïve theory that is more similar to a dynamical than a non-dynamical theory. Interestingly, while we found stable results across our (...) two experiments regarding the percentage of participants that have a dynamical or non-dynamical extant theory of time, we did not find such stability regarding which particular dynamical or non-dynamical theory of time they take to be most similar to our world. This suggests that there might be two extant theories in the population—a broadly dynamical one and a broadly non-dynamical one—but that those theories are sufficiently incomplete that participants do not stably choose the same dynamical theory as being most similar to our world. This suggests that while appeals to the ordinary view of time may do some work in the context of adjudicating disputes between dynamists and non-dynamists, they likely cannot do any such work adjudicating disputes between particular brands of dynamism.

This paper empirically investigates one aspect of the folk concept of time by testing how the presence or absence of directedness impacts judgements about whether there is time in a world. Experiment 1 found that dynamists, showed significantly higher levels of agreement that there is time in dynamically directed worlds than in non-dynamical non-directed worlds. Comparing our results to those we describe in Latham et al., we report that while ~ 70% of dynamists say there is time in B-theory worlds, (...) only ~ 45% say there is time in C-theory worlds. Thus, while the presence of directedness makes dynamists more inclined to say there is time in a world, a substantial subpopulation of dynamists judge that there is time in non-directed worlds. By contrast, a majority of non-dynamists judged that there was time in both growing block worlds and C-theory worlds, with no significant differences between the means. Experiment 2 found that when participants are only presented with non-dynamical worlds—namely, a directed world and a non-directed world—they report significantly higher levels of agreement that there is time in B-theory worlds. However, the majority of participants still judge that there is time in C-theory worlds. We conclude that while the presence of directedness bolsters judgements that there is time, most people do not judge it to be necessary for time. (shrink)

Empirical work has lately confirmed what many philosophers have taken to be true: people are ‘biased toward the future’. All else being equal, we usually prefer to have positive experiences in the future, and negative experiences in the past. According to one hypothesis, the temporal metaphysics hypothesis, future-bias is explained either by our beliefs about temporal metaphysics—the temporal belief hypothesis—or alternatively by our temporal phenomenology—the temporal phenomenology hypothesis. We empirically investigate a particular version of the temporal belief hypothesis according to (...) which future-bias is explained by the belief that time robustly passes. Our results do not match the apparent predictions of this hypothesis, and so provide evidence against it. But we also find that people give more future-biased responses when asked to simulate a belief in robust passage. We take this to suggest that the phenomenology that attends simulation of that belief may be partially responsible for future-bias, and we examine the implications of these results for debates about the rationality of future-bias.

Ethical deliberations are unfolding for potentially controversial organoid‐entities such as brain organoids and embryoids. Much of the ethical deliberation centers on the questionable moral status of such organoid‐entities. However, while such work is important and appropriate, ethical deliberations may become too exclusively rooted in moral status and potentially overshadow other relevant moral dilemmas. The ethical discussion on organoid models can benefit from insights brought forth by both Judith Jarvis Thomson and Don Marquis in how they attempted to advance the abortion (...) debate. To discuss other abortion ethical issues more fully, both Thomson and Marquis assumed differing moral status positions of the conceptus and followed lines of reasoning based on these moral status assumptions. We suggest a similar approach with controversial organoid‐entities like brain organoids and embryoids. To avoid overshadowing or overlooking other relevant ethical issues, ethicists ought to first assume an organoid‐entity moral status position (such as a high moral status or no moral status) and explore any possible arguments that may result from such a position. While we ought not to copy the content of Thomson and Marquis' arguments exactly for organoid‐entities, it is worthwhile to translate their arguments' overarching structures. This paper explores the relevant insights of Thomson and Marquis, how they can be translated into the organoid ethics debate, and what possible lines of inquiry may be worth exploring based on particular moral status assumptions.

Cerebral organoid models in-of-themselves are considered as an alternative to research animal models. But their developmental and biological limitations currently inhibit the probability that organoids can fully replace animal models. Furthermore, these organoid limitations have, somewhat ironically, brought researchers back to the animal model via xenotransplantation, thus creating hybrids and chimeras. In addition to attempting to study and overcome cerebral organoid limitations, transplanting cerebral organoids into animal models brings an opportunity to observe behavioral changes in the animal itself. Traditional animal (...) ethics frameworks, such as the well-known three Rs (reduce, refine, and replace), have previously addressed chimeras and xenotransplantation of tissue. But these frameworks have yet to completely assess the neural-chimeric possibilities. And while the three Rs framework was a historical landmark in animal ethics, there are identifiable gaps in the framework that require attention. The authors propose to utilize an expanded three Rs framework initially developed by David DeGrazia and Tom L. Beauchamp, known as the Six Principles (6Ps). This framework aims to expand upon the three Rs, fill in the gaps, and be a practical means for assessing animal ethical issues like that of neural-chimeras and cerebral organoid xenotransplantation. The scope of this 6Ps application will focus on two separate but recent studies, which were published in 2019 and 2020. First, they consider a study wherein cerebral organoids were grown from donors with Down syndrome and from neurotypical donors. After these organoids were grown and studied, they were then surgically implanted into mouse models to observe the physiological effects and any behavioral change in the chimera. Second, they consider a separate study wherein neurotypical human embryonic stem cell-derived cerebral organoids were grown and transplanted into mouse and macaque models. The aim was to observe if such a transplantation method would contribute to therapies for brain injury or stroke. The authors place both studies under the lens of the 6Ps framework, assess the relevant contexts of each case, and provide relevant normative conclusions. In this way, they demonstrate how the 6Ps could be applied in future cases of neural-chimeras and cerebral organoid xenotransplantation. (shrink)

Deflationists hold that it does not seem to us, in experience, as though time robustly passes. There is some recent empirical evidence that appears to support this contention. Equally, empirical evidence suggests that we naïvely represent time as dynamical. Thus deflationists are faced with an explanatory burden. If, as they maintain, the world seems to us in experience as though it is non-dynamical, then why do we represent time as dynamical? This paper takes up the challenge of investigating, on the (...) part of the deflationist, one candidate explanation. We hypothesise that people’s belief that the future is what we call deliberatively open partly explains why they represent time as dynamical. In a series of two experiments we test this hypothesis. We find no evidence that beliefs about deliberative openness explain why people represent time as dynamical. Hence there remains an explanatory burden for the deflationist to discharge. (shrink)

It has widely been assumed, by philosophers, that most people unambiguously have a phenomenology as of time passing, and that this is a datum that philosophical theories must accommodate. Moreover, it has been assumed that the greater the extent to which people have said phenomenology, the more likely they are to endorse a dynamical theory of time. This paper is the first to empirically test these assumptions. Surprisingly, our results do not support either assumption. One experiment instead found the reverse (...) correlation: people were more likely to report having passage phenomenology if they endorsed a non-dynamical theory of time. Given that people do not have an unambiguous phenomenology as of time passing, we conclude that this is suggestive evidence in favor of veridical non-dynamism—the view that our phenomenology is veridical, and that it does not unambiguously represent that time passes. Instead, our phenomenology veridically has some quite different content. (shrink)

Recent research (Latham, Miller and Norton, forthcoming) reveals that a majority of people represent actual time as dynamical. But do they, as suggested by McTaggart and Gödel, represent time as essentially dynamical? This paper distinguishes three interrelated questions. We ask (a) whether the folk representation of time is sensitive or insensitive: i.e., does what satisfies the folk representation of time in counterfactual worlds depend on what satisfies it actually—sensitive—or does is not depend on what satisfies it actually—insensitive, and (b) do (...) those who represent actual time as dynamical, represent time in all possible worlds as dynamical—what we call insensitive dynamism—or do they represent time in all possible worlds as dynamical only conditional on the actual world in fact being dynamical—what we call sensitive dynamism and (c) do dynamists and non-dynamists deploy two different representations of time, or deploy the same representation, but disagree about what actually satisfies that representation? We found no evidence that the folk representation of time is sensitive, or that the folk representation of time is essentially dynamical in either sense, though we did find evidence of a shared representation, on which dynamical features are sufficient, but not necessary, for time.

People are ‘biased toward the future’: all else being equal, we typically prefer to have positive experiences in the future, and negative experiences in the past. Several explanations have been suggested for this pattern of preferences. Adjudicating among these explanations can, among other things, shed light on the rationality of future-bias: For instance, if our preferences are explained by unjustified beliefs or an illusory phenomenology, we might conclude that they are irrational. This paper investigates one hypothesis, according to which future-bias (...) is explained by our having a phenomenology that we describe, or conceive of, as being as of time robustly passing. We empirically tested this hypothesis and found no evidence in its favour. Our results present a puzzle, however, when compared with the results of an earlier study. We conclude that although robust passage phenomenology on its own probably does not explain future-bias, having this phenomenology and taking it to be veridical may contribute to future-bias.

In this paper I will introduce a new compatibilist account of free action: indirect conscious control compatibilism, or just indirect compatibilism for short. On this account, actions are free either when they are caused by compatibilist‐friendly conscious psychological processes, or else by sub‐personal level processes influenced in particular ways by compatibilist‐friendly conscious psychological processes. This view is motivated by a problem faced by a certain family of compatibilist views, which I call conscious control views. These views hold that we act (...) freely when we act in a way that is caused by certain conscious psychological processes. One problem for such views is that current neuroscience suggests that most of our actions are not caused by such processes. Instead, many of the actions we typically suppose are free are caused by sub‐personal level processes and hence would count as not free according to contemporary conscious control views. I argue, contra these views, that many actions caused by these sub‐personal level processes are indirectly free. Further, most of the actions we ordinarily judge to be free are free in this indirect manner. (shrink)

Many manipulation arguments against compatibilism rely on the claim that manipulation is relevantly similar to determinism. But we argue that manipulation is nothing like determinism in one relevant respect. Determinism is a "universal" phenomenon: its scope includes every feature of the universe. But manipulation arguments feature cases where an agent is the only manipulated individual in her universe. Call manipulation whose scope includes at least one but not all agents "existential manipulation." Our responsibility practices are impacted in different ways by (...) universal and existential phenomena. And this is a relevant difference, especially on Strawsonian approaches to moral responsibility, which take facts about our responsibility practices to be deeply connected to the nature of responsibility itself. We argue that Strawsonian accounts of moral responsibility are immune to manipulation arguments, and no attempt to modify the scope of manipulation or determinism featured in these arguments will help incompatibilists secure their desired conclusion.

Philosophers have long noted, and empirical psychology has lately confirmed, that most people are “biased toward the future”: we prefer to have positive experiences in the future, and negative experiences in the past. At least two explanations have been offered for this bias: belief in temporal passage and the practical irrelevance of the past resulting from our inability to influence past events. We set out to test the latter explanation. In a large survey, we find that participants exhibit significantly less (...) future bias when asked to consider scenarios where they can affect their own past experiences. This supports the “practical irrelevance” explanation of future bias. It also suggests that future bias is not an inflexible preference hardwired by evolution, but results from a more general disposition to “accept the things we cannot change”. However, participants still exhibited substantial future bias in scenarios in which they could affect the past, leaving room for complementary explanations. Beyond the main finding, our results also indicate that future bias is stake-sensitive and that participants endorse the normative correctness of their future-biased preferences and choices. In combination, these results shed light on philosophical debates over the rationality of future bias, suggesting that it may be a rational response to empirical realities rather than a brute, arational disposition.

Some postcolonial theorists argue that the idea of a single system of belief known as "Hinduism" is a creation of nineteenth-century British imperialists. Andrew J. Nicholson introduces another perspective: although a unified Hindu identity is not as ancient as some Hindus claim, it has its roots in innovations within South Asian philosophy from the fourteenth to seventeenth centuries. During this time, thinkers treated the philosophies of Vedanta, Samkhya, and Yoga, along with the worshippers of Visnu, Siva, and Sakti, as (...) belonging to a single system of belief and practice. Instead of seeing such groups as separate and contradictory, they re-envisioned them as separate rivers leading to the ocean of Brahman, the ultimate reality. Drawing on the writings of philosophers from late medieval and early modern traditions, including Vijnanabhiksu, Madhava, and Madhusudana Sarasvati, Nicholson shows how influential thinkers portrayed Vedanta philosophy as the ultimate unifier of diverse belief systems. This project paved the way for the work of later Hindu reformers, such as Vivekananda, Radhakrishnan, and Gandhi, whose teachings promoted the notion that all world religions belong to a single spiritual unity. In his study, Nicholson also critiques the way in which Eurocentric concepts—like monism and dualism, idealism and realism, theism and atheism, and orthodoxy and heterodoxy—have come to dominate modern discourses on Indian philosophy.

In a recent article in this journal, Andrew Johnson seeks to defend the “New Atheism” against several objections. We provide a philosophical assessment of his defense of contemporary atheistic arguments that are said to amount to bifurcation fallacies. This point of discussion leads to our critical discussion of the presumption of atheism and the epistemic justification of atheism.

In a recent paper, Keith Hutchison has advanced the thesis that the Mechanical Philosophy represents a shift towards supernaturalism in our conception of the physical world. This paper concentrates on one of the great problems of seventeenth-century biological theory — animal generation — to illustrate (and modify) Hutchison's thesis, thereby also serving to locate one role of the life sciences in the Scientific Revolution. This choice of focus enables us to draw heavily on Jacques Roger's seminal work on animal generation (...) to illuminate the change that occurs, within the Mechanical Philosophy, between Descartes and Malebranche. Once the necessary distinctions have been drawn, it is argued, it will be seen that (in one important sense) this is a shift from naturalism to supernaturalism, brought about largely by problems native to the life sciences.

Empirical evidence shows that people have multiple time-biases. One is near-bias; another is future-bias. Philosophical theorising about these biases often proceeds on two assumptions. First, that the two biases are _independent_: that they are explained by different factors (the independence assumption). Second, that there is a normative asymmetry between the two biases: one is rationally impermissible (near-bias) and the other rationally permissible (future-bias). The former assumption at least partly feeds into the latter: if the two biases were not explained by (...) different factors, then it would be less plausible that their normative statuses differ. This paper investigates the independence assumption and finds it unwarranted. In light of this, we argue, there is reason to question the normative asymmetry assumption. (shrink)

There are two kinds of time-bias: near-bias and future-bias. While philosophers typically hold that near-bias is rationally impermissible, many hold that future-bias is rationally permissible. Call this normative hybridism. According to arbitrariness objections, certain patterns of preference are rationally impermissible because they are arbitrary. While arbitrariness objections have been levelled against both near-bias and future-bias, the kind of arbitrariness in question has been different. In this paper we investigate whether there are forms of arbitrariness that are common to both kinds (...) of preferences, and hence whether there are versions of the arbitrariness objection that are objections both to near-bias and future-bias. If there are, then this might go some way towards undermining normative hybridism and to defending a thorough-going time-neutralism. (shrink)

Many philosophers hold that ‘one-instant worlds’—worlds that contain a single instant—fail to contain time. We experimentally investigate whether these worlds satisfy the folk concept of time. We found that ~50% of participants hold that there is time in such worlds. We argue that this suggests one of two possibilities. First, the population disagree about whether at least one of the A-, B-, or C-series is necessary for time, with there being a substantial sub-population for whom the presence of neither an (...) A-, B-, nor C-series, is necessary for time, and hence those folk have a radically more minimal concept of time than has been attributed to them by philosophers. Or, second, the population do not disagree about whether at least one of the A-, B-, or C-series is necessary for time, but disagree about what it takes for a world to fail to contain even a C-series.

This paper empirically investigates the contention that the folk concept of time is a functional concept: a concept according to which time is whatever plays a certain functional role or roles. This hypothesis could explain why, in previous research, surprisingly large percentages of participants judge that there is time at worlds that contain no one-dimensional substructure of ordered instants. If it seems to participants that even in those worlds the relevant functional role is played, then this could explain why they (...) judge that there is time in those worlds. While our experiment supported the finding that participants are reticent to judge that there is no time, actually, we found no evidence that this is because they deploy a functionalist concept, at least of the kind proposed in recent research. Our findings are, however, consistent with the folk deploying a much more minimal functionalist concept according to which time is just whatever it is—regardless of its nature—that plays the role of grounding our temporal phenomenology.

I argue that when we use email, text messaging, or social media websites such as Facebook to interact, rather than communicating face-to-face, we do not experience the best kind of empathy, which is most conducive to experiencing benevolence for others. My arguments rely on drawing interdisciplinary connections between sources: early modern accounts of sympathy, dance theory, philosophy of technology, and neuroscience/psychology. I reflect on theories from these disciplines which, taken together, suggest that to empathize optimally, we must see or hear (...) each other’s bodily gestures, vocal intonations, and facial expressions.

Empirical evidence suggests that a majority of people believe that time robustly passes, and that many also report that it seems to them, in experience, as though time robustly passes. Non-dynamists deny that time robustly passes, and many contemporary non-dynamists—deflationists—even deny that it seems to us as though time robustly passes. Non-dynamists, then, face the dual challenge of explaining why people have such beliefs and make such reports about their experiences. Several philosophers have suggested the stable-self explanation, according to which (...) what partly explains one or both of the explananda is that people believe themselves to have a stable persisting self which is imagined either as moving through time, or as being stationary, with time moving around it. This paper empirically investigates this explanation. We found, however, no evidential support for the stable-self explanation, leaving the non-dynamist but also, we will argue, the dynamist, with an extant explanatory challenge. (shrink)

This paper offers a composite portrait of the concept of magnanimity in nineteenth-century America, focusing on Ralph Waldo Emerson, Margaret Fuller, and Henry David Thoreau. A composite portrait, as a method in the history of philosophy, is designed to bring out characteristic features of a group's philosophizing in order to illuminate characteristic features that may still resonate in today's philosophy. Compared to more standard methods in the historiography of philosophy, the construction of a composite portrait de-privileges the views of individual (...) authors. These philosophers saw the virtue of magnanimity as a remedy for a number of modern ills. American philosophers suggest that the best sort of magnanimity is acquired by adopting the correct relation to the natural world, including new forms of inquiry, or by adopting a life of voluntary poverty. Magnanimous individuals are critics of capitalism and offer themselves as exemplars of a better, experimental life. (shrink)

This paper argues for a view of free will that I will call the conceptual impossibility of the truth of free will error theory - the conceptual impossibility thesis. I will argue that given the concept of free will we in fact deploy, it is impossible for our free will judgements - judgements regarding whether some action is free or not - to be systematically false. Since we do judge many of our actions to be free, it follows from the (...) conceptual impossibility thesis that many of our actions are in fact free. Hence it follows that free will error theory - the view that no judgement of the form ‘action A was performed freely’ - is false. I will show taking seriously the conceptual impossibility thesis helps makes good sense of some seemingly inconsistent results in recent experimental philosophy work on determinism and our concept of free will. Further, I will present some reasons why we should expect to find similar results for every other factor we might have thought was important for free will. (shrink)

Some philosophers contend that to effectively address problems such our global environmental crisis, humans must collectively embrace a polyphonic, environmentalist grand narrative, very different from the narratives accepted by modernists. Cultural theorists who write about metamodernism likewise discuss the recent return to a belief in narratives, and contend that our society’s current approach to narratives is very different from that of the modernists. In this paper, I articulate these philosophers’ and cultural theorists’ positions, and I highlight and explore interconnections between (...) them. Additionally, I argue that if the authors I discuss are correct, then we morally ought to embrace a metamodernist, polyphonic, environmentalist grand narrative, in order to effectively address an array of global crises. Such a grand narrative is a necessary ingredient of an adequate global ethics. (shrink)

Thomas Hobbes contends that a wise sovereign would censor books and limit verbal discourse for the majority of citizens. But this article contends that it is consistent with Hobbes’s philosophy to claim that a wise sovereign would allow a small number of citizens – those individuals who engage in scientific discourse and who are magnanimous and just – to disagree freely amongst themselves, engaging in discourse on controversial topics. This article reflects on Hobbes’s contention that these individuals can tolerate one (...) another’s differences and engage in verbal disagreement without any risk to the commonwealth. By engaging in open discourse, these individuals can better create valuable technology and provide counsel to the sovereign that is necessary to maintain peace. (shrink)

Evidence has accumulated that rod activation under mesopic and scotopic light levels alters visual perception and performance. Here we review the most recent developments in the measurement of rod and cone contributions to mesopic color perception and temporal processing, with a focus on data measured using the four-primary photostimulator method that independently controls rod and cone excitations. We discuss the findings in the context of rod inputs to the three primary retinogeniculate pathways to understand rod contributions to mesopic vision. Additionally, (...) we present evidence that hue perception is possible under scotopic, pure rod-mediated conditions that involves cortical mechanisms. (shrink)

Four experiments supported the hypothesis that ordinary people understand free will as meaning unconstrained choice, not having a soul. People consistently rated free will as being high unless reduced by internal constraints (i.e., things that impaired people’s mental abilities to make choices) or external constraints (i.e., situations that hampered people’s abilities to choose and act as they desired). Scientific paradigms that have been argued to disprove free will were seen as reducing, but usually not eliminating free will, and the reductions (...) were because of constrained conscious choice. We replicated findings that a minority of people think lacking a soul reduces free will. These reductions in perceived free will were fully explained by reductions in people’s perceived abilities to make conscious decisions. Thus, some people do think you need a soul to have free will—but it is because they think you need a soul to make conscious decisions. (shrink)

I contend that Adam Smith and David Hume offer re-interpretations of Aristotle’s notion of greatness of soul, focusing on the kind of magnanimity Aristotle attributes to Socrates. Someone with Socratic magnanimity is worthy of honor, responds moderately to fortune, and is virtuous—just and benevolent. Recent theorists err in claiming that magnanimity is less important to Hume’s account of human excellence than benevolence. In fact, benevolence is a necessary ingredient for the best sort of greatness. Smith’s “Letter to Strahan” attributes this (...) greatness to Hume. It encourages us to admire Hume as an exemplar of human excellence, to seek Hume’s virtues for ourselves, and to approve of the “love of literary fame” which Hume calls his “ruling passion.”.

Thomas Hobbes’s concept of magnanimity, a descendant of Aristotle’s “greatness of soul,” plays a key role in Hobbes’s theory with respect to felicity and the virtue of justice. In his Critique du ‘De Mundo’, Hobbes implies that only genuinely magnanimous people can achieve the greatest felicity in their lives. A life of felicity is a life of pleasure, where the only pleasure that counts is the well grounded glory experienced by those who are magnanimous. Hobbes suggests that felicity involves the (...) successful pursuit of desires, a pursuit at which the magnanimous are particularly adept. Additionally, Hobbes implies that those who possess the virtue of justice must also possess magnanimity; it is the just person’s “Nobleness or Gallantnesse of courage, (rarely found).” Leo Strauss and Dorothea Krook suggest that this cannot be Hobbes’s “final word” on justice, because, they say, Hobbes considers magnanimity a type of pride, which he derogates and cannot consistently associate with virtue. I argue that magnanimity, associated with well-grounded glory, is not a type of pride; only vain glory is. (shrink)
