Memory should make more available things that are more likely to be needed. Across multiple environmental domains, it has been shown that such a system would match qualitatively the memory effects involving repetition, delay, and spacing (Schooler & Anderson, 2017). To obtain data of sufficient size to study how detailed patterns of past appearance predict probability of being needed again, we examined the patterns with which words appear in large two data sets: tweets from popular sources and comments on popular (...) subreddits. The two data sets show remarkably similar statistics, which are also consistent with earlier, smaller studies of environmental statistics. None of a candidate set of mathematical models of memory do well at predicting the observed patterns in these environments. A new model of human memory based on the environmental model proposed by Anderson and Milson (1989) did better at predicting the environmental data and a wide range of behavioral studies that measure memory availability by probability of recall and speed of retrieval. A critical variable in this model was range, the span of time over which an item occurs, which was discovered in mining the environmental data. These results suggest that theories of memory can be guided by mining of the statistical structure of the environment. (PsycInfo Database Record (c) 2023 APA, all rights reserved). (shrink)

Open‐ended tasks can be decomposed into the three levels of Newell's Cognitive Band: the Unit‐Task level, the Operation level, and the Deliberate‐Act level. We analyzed the video game Co‐op Space Fortress at these levels, reporting both the match of a cognitive model to subject behavior and the use of electroencephalogram (EEG) to track subject cognition. The Unit Task level in this game involves coordinating with a partner to kill a fortress. At this highest level of the Cognitive Band, there is (...) a good match between subject behavior and the model. The EEG signals were also strong enough to track when Unit Tasks succeeded or failed. The intermediate Operation level in this task involves legs of flight to achieve a kill. The EEG signals associated with these operations are much weaker than the signals associated with the Unit Tasks. Still, it was possible to reconstruct subject play with much better than chance success. There were significant differences in the leg behavior of subjects and models. Model behavior did not provide a good basis for interpreting a subject's behavior at this level. At the lowest Deliberate‐Act level, we observed overlapping key actions, which the model did not display. Such overlapping key actions also frustrated efforts to identify EEG signals of motor actions. We conclude that the Unit‐task level is the appropriate level both for understanding open‐ended tasks and for using EEG to track the performance of open‐ended tasks. (shrink)

We studied collaborative skill acquisition in a dynamic setting with the game Co-op Space Fortress. While gaining expertise, the majority of subjects became increasingly consistent in the role they adopted without being able to communicate. Moreover, they acted in anticipation of the future task state. We constructed a collaborative skill acquisition model in the cognitive architecture ACT-R that reproduced subject skill acquisition trajectory. It modeled role adoption through reinforcement learning and predictive processes through motion extrapolation and learned relevant control parameters (...) using both a reinforcement learning procedure and a new to ACT-R supervised learning procedure. This is the first integrated cognitive model of collaborative skill acquisition and, as such, gives us valuable insights into the multiple cognitive processes that are involved in learning to collaborate.

Learning to solve a class of problems can be characterized as a search through a space of hypotheses about the rules for solving these problems. A series of four experiments studied how different learning conditions affected the search among hypotheses about the solution rule for a simple computational problem. Experiment 1 showed that a problem property such as computational difficulty of the rules biased the search process and so affected learning. Experiment 2 examined the impact of examples as instructional tools (...) and found that their effectiveness was determined by whether they uniquely pointed to the correct rule. Experiment 3 compared verbal directions with examples and found that both could guide search. The final experiment tried to improve learning by using more explicit verbal directions or by adding scaffolding to the example. While both manipulations improved learning, learning still took the form of a search through a hypothesis space of possible rules. We describe a model that embodies two assumptions: the instruction can bias the rules participants hypothesize rather than directly be encoded into a rule; participants do not have memory for past wrong hypotheses and are likely to retry them. These assumptions are realized in a Markov model that fits all the data by estimating two sets of probabilities. First, the learning condition induced one set of Start probabilities of trying various rules. Second, should this first hypothesis prove wrong, the learning condition induced a second set of Choice probabilities of considering various rules. These findings broaden our understanding of effective instruction and provide implications for instructional design. (shrink)

Currently, an increasing number of organizations are attempting to enhance inclusiveness of under represented individuals through proactive efforts to manage their diversity. In this article, we define diversity management against the backdrop of its predecessor, affirmative action. Next, selected examples of organizations that have experienced specific positive bottom line results from diversity management strategies are discussed. The present paper also provides a conceptual model to examine antecedents and consequences of effective diversity management. Additional research areas identified from the model and (...) literature review result in a number of research propositions intended to enhance the exploration and understanding of diversity management.

Summary John Harrison (1693–1776) is regarded as the father of chronometry. During his lifetime, he relentlessly pursued one of humankind's greatest and oldest challenges—that of finding the longitude at sea. In succeeding (according to the rules dictated by an Act of Parliament), he bequeathed to humankind the most accurate portable timekeeper the world had ever seen. It is a remarkable fact that his timekeeper, known today as H4, remains more accurate than the majority of expensive mechanical wristwatches manufactured today. (...) Such accuracy required novel approaches to address the various difficulties that befall all mechanical watches, and Harrison overcame many of these with his own innovations. The reduction or elimination of friction is one such problem with clocks and watches, and from an early age Harrison demonstrated his mastery in this subject. This is typified by his choice of woods in his early clocks, and in later clocks by his ‘grasshopper’ escapement. In the 1750s, Harrison's attention switched from clocks to watches, necessitating a hardwearing, low friction material to be found for the pallets in the escapement of his timekeepers. He found these properties in diamond, and in utilizing this to great effect in H4's escapement, he became one of the first people to use diamond as a high-tech material. This paper describes a scientific investigation into the diamond pallets of H4 using Raman microscopy, X-ray diffraction and optical microscopy, to elucidate why diamond was used rather than a more conventional jewel such as ruby, and to gain some insight into how Harrison might have achieved their unconventional morphology. From the evidence presented here, together with evidence collected from primary sources, it is shown that his use of diamond as a hard, low friction material was nothing other than extraordinary, and should be regarded in the same high esteem as his other technological gifts to the world.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Against the Ethicists (Adversus Mathematicos XI) by Sextus EmpiricusJohn Christian LaursenSextus Empiricus. Against the Ethicists (Adversus Mathematicos XI). Translation, Commentary, and Introduction by Richard Bett. Oxford: Clarendon Press, 1997. Pp. xxxiv + 302. NP.Sesto Empirico. Contro gli etici. Introduction, Editing, Translation, and Commentary by Emidio Spinelli. Naples: Bibliopolis, 1995. Pp. 450. NP.Joining the rising tide of scholarly literature that says that skeptics can indeed live their skepticism, and (...) that it is not necessarily a bad life, are these two fine translations of Book XI of Sextus Empiricus’s Against the Mathematicians (known as MXI), the most important for ethics and politics. Considering that the length of Sextus’s text is only 39 pages (in the English version), the length of these two volumes alone indicates that a great deal of philosophical and philological scholarship will be found in them. Both authors do an excellent job of tracking down Sextus’s sources and his targets.Spinelli accepts the traditional position (Janacek’s) that MXI was written after Sextus’s Outlines of Pyrrhonism, although he is aware of the minority position that it was the other way around. Bett makes a convincing case for the minority position, including a substantial appendix comparing passages from the two works which suggest that Outlines polishes MXI. This has the merit of explaining Sextus’s apparent “negative dogmatism” in MXI as part of early skepticism and a phase on the way to the more refined and more thoroughly undogmatic skepticism of the Outlines. However, Bett himself mentions counterevidence to his thesis, so it cannot be considered decisively established. Spinelli explains the apparent dogmatism on the assumption that Outlines came first: the usual skeptical reservations set forth in that book should be understood as implied (165–66, 169). Other explanations are that apparent affirmations are ad hominem polemic “inside” Stoic theory (240ff.) or merely relative and with no ontological status (291).Bett divides the text into part A (1–167) and part B (168–end), arguing for compilation of the two parts of the book from different sources with different purposes. Spinelli writes that the often-denigrated 168–end “has a precise function in the internal compositional strategy” of the book (339).English speakers have had to rely too long on the Loeb translation by” B. Bury. Bett questions many of his renderings. For example, Bury translated kakon and kakia as “evil,” with connotations of intentionality, and at MXI 121 even supplied a footnote to Genesis! Bett prefers the less-loaded “bad” and “vice.” Spinelli usually translates kakon with “mali” but uses the loaded “malvagità” for kakia at MXI 121, where Bett would have suggested “vizio.” Bury translated alogon and alogois with “irrational” which Bett corrects to “non-rational” at MXI 143, 148, and 161 to capture the point that what is in question is neither rational nor irrational, but rather “sensory happenings” which have [End Page 313] nothing to do with reasoning (161). Spinelli renders alogon as “irrazionale” at MXI 143 and alogois as “sottrati al ragionamento” at MXI 148 and 161.Spinelli’s is a much more useful and substantial volume than the previous Italian translation. The only thing that might keep Bett’s volume from replacing the Loeb edition is that it does not supply the Greek text on facing pages. Spinelli does.The exhaustive and careful analyses of Spinelli and Bett allow them to disagree in important ways with parts of the substantial recent work on ancient skepticism by Hankinson, McPherran, Annas, Nussbaum, Striker, and Decleva Caizzi (cited as Caizzi by Bett), not to mention the older work of Janacek and the debates from the early 1980s (now dated) among Frede, Burnyeat, and Barnes. Although they do not find Sextus’s work to be flawless by any means, it is clear that we are long past the point at which his work could be dismissed as silly or merely derivative.On the test case of the treatment of Sextus’s example of the tyrant (MXI 166), both Spinelli and Bett point in the right direction. Spinelli sees that “the Pyrrhonist can live easily” (330) and that MXI 165–67 provides “a new key to understanding the ‘moral skepticism... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 41.1 (2003) 125-126 [Access article in PDF] Sextus Empiricus. Against the Grammarians (Adversos Mathematicos I). Introduction, Commentary, and Translation by D. L. Blank. Oxford: Clarendon Press, 1998. Pp. lvi + 436. Cloth, $105.00. Sesto Empirico. Contro gli astrologi. Introduction, Commentary, and Translation by Emidio Spinelli. Naples: Bibliopolis, 2000. Pp. 230. Paper, L. 70.000. No historian of philosophy should be retailing the old canards (...) that the Hellenistic philosopher Sextus Empiricus was silly, wholly confused, or merely a compiler and not a philosopher in his own right. These translations and commentaries, along with the recent work of Richard Bett, James Hankinson, and others, should bury those notions forever.Against the Grammarians is the first and Against the Astrologers is the fifth volume of Sextus's six-volume Against the Teachers of the technai or professional arts and sciences (grammar, rhetoric, geometry, arithmetic, astrology, and music). Sextus is not against all forms of the study of these matters; in fact, one of the skeptic's "rules for living" is that he will engage in an art (techne) to make a living (Outlines of Pyrrhonism, I.24). But he is against the claims of each of them to special technical expertise. He prefers the unpretentious experience of everyday life—living by the phenomena; non-expert, practical forms of grammar, astronomy, music—to fancy theories about the nature of things.Against the Grammarians is Sextus's critique of the interpreters of poetry and prose—today's English professors and historians. Philosophers will be amused by his deconstruction of various sorts of lit crit arrogance and rashness that are still with us. Regrettably, some of us are not immune from the same critiques.Against the Astrologers is Sextus's critique of the Chaldean soothsayers. He is not against the observation of celestial phenomena for agricultural or navigational purposes. His critiques of the astrologers for lack of empirical evidence and promotion of superstition make him sound like a proto-scientist.One originality of Sextus's work was his combination of a dogmatic Epicurean critique of the grammatologists and astrologers with a skeptical aporetic critique. Precisely because he does not hesitate to make use of the arguments of others, some interpreters have decided that Sextus was unoriginal and derivative. But Blank and Spinelli both show that he recombines these arguments in ways that no one else had done. That is one of the ways of being original in philosophy. The upshot is that he is our earliest source of quite a number of critiques of grammarians and astrologers.The use of dogmatic arguments raises the problem of whether Sextus engages in so-called "negative dogmatism" in these volumes. Right at the beginning of Against the Astrologers, Sextus accuses them of violating "right reason." What right does a skeptic have to invoke such a standard? Some have felt that at this stage Sextus was a dogmatic skeptic, invoking one set of truths to tear down another. But that is not necessary. Blank and Spinelli explain this well with a combination of points. One, we can see the dogmatic and Epicurean attacks as clearing the ground for the following skeptical equipollence of arguments. Two, we can follow Jonathan Barnes in assuming that each claim that something has been demolished assumes the counterargument that it has been proven, so that the implied upshot is equipollence. Three, "right reason" can be the sort of unpretentious practical reasoning and living in accord with the appearances that the skeptics often claimed to live by.Spinelli and Blank provide many useful improvements over the previous English translations of these texts by Bury and the Italian translations by Russo. Blank rightly relies on Spinelli's 1995 translation and commentary on Sextus's Against the Ethicists and Spinelli rightly relies on Blank for a number of points. Spinelli supplies the Greek on facing pages of the translation; Blank does not. Spinelli also supplies five Greek zodiac charts and a beautiful print of a fifteenth-century zodiac.Neither Blank nor Spinelli unduly lionizes Sextus. They admit that... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 40.1 (2002) 116-118 [Access article in PDF] Book Review Pyrrho, His Antecedents, and His Legacy Philo of Larissa: The Last of the Academic Sceptics Richard Bett. Pyrrho, His Antecedents, and His Legacy. New York: Oxford University Press, 2000. Pp. x + 264. Cloth, $60.00. Charles Brittain. Philo of Larissa: The Last of the Academic Sceptics. New York: Oxford University Press, 2001. Pp. xii (...) + 406. Cloth, $60.00. These two books demonstrate once again that the ancient skeptics could indeed live their skepticism. In recent decades Myles Burnyeat, Benson Mates, and too many others have retailed the old canard that the skeptic cannot live his skepticism, but here we have two branches of ancient skepticism that sound quite liveable. Both books are subtle and brilliant examples of the genre of reconstructing philosophy from meager and fragmentary evidence.Bett's book follows up on the case he made in his 1997 translation of Sextus Empiricus's Against the Ethicists for three stages in ancient Pyrrhonism. The first is that of Pyrrho (ca. 360-ca. 270 B.C.), a dogmatist who held what Bett labels the indeterminacy thesis: we do not know anything because the world is indeterminate and thus we cannot know it. The second is a similarly dogmatic stage under Aenesidemus (first century B.C.), also followed by Sextus in Against the Ethicists. The third is the more thoroughly skeptical suspension of judgment of the mature Sextus of the Outlines of Pyrrhonism (second century A.D.). Bett points out that it would indeed be odd if Pyrrhonism had not evolved in any way in five hundred years. What was unique throughout the tradition was the connection drawn between indeterminacy or suspension of judgment and the goal of ataraxia or tranquility (179, 220).Bett tries to avoid reading later concerns back into the earlier materials, and reevaluates the later materials based on his new reading of the earlier. He argues that Pyrrho's indeterminacy thesis was a metaphysical claim, not an epistemological one. One benefit of [End Page 116] understanding Pyrrho this way is that he does not make a self-refuting exception to his epistemological skepticism for his own claims. Rather, he can just admit to being a kind of dogmatist. Then, Pyrrho's ethical dogmatism is also perfectly consistent. Bett draws a picture of Pyrrho's practical life that rejects the walking-off-of-cliffs apocrypha, but accepts evidence of a quasi-Cynic, anti-theoretical lifestyle. Pyrrho's rejection of social norms puts him at odds with Sextus's later use of laws and customs as guides to behavior. There are still further questions here: why was Pyrrho in particular such a hero to philosophers, if most (or at least many) people are resolutely non-theoretical?Bett points out that Pyrrho gives us no reason to think that the abandonment of theories and opinions must always lead to tranquility (81). But in another connection, he recognizes that temperament may be decisive (111), and that may be the deciding factor here, too. There is no answer to people who say that abandoning theories makes them nervous: the Pyrrhonians simply say that it makes them tranquil. Irreducible differences in temperament may also explain why Pyrrho did not bother with theoretical controversy and Sextus revelled in it.Among other points, Bett discourages all but the most general case for an influence from India on Pyrrho. Bett's thumbnail comparisons between Pyrrho and each of Aristotle, Plato, the Eleatics, Xenophanes, and others show that Pyrrho's philosophy was not at all extraordinary for its time and place. Most philosophers expected claims about nature to be invariable and without qualification (118). Bett says this is odd by modern standards (197), but even today scientific laws are said to apply to all times and all places.The title of Bett's book will mislead some readers. If you are a specialist and your world revolves around ancient philosophy, you will be satisfied that Pyrrho's "legacy" includes Aenesidemus and ends... (shrink)

This volume explores the relationship between rationality and happiness from ancient Greek philosophy to early Latin medieval philosophy. What connection is there between human rationality and happiness? This issue was uppermost in the minds of the Ancient Greek philosophers and continued to be of importance during the entire early medieval period. Starting with theSocrates of Plato's early dialogues, who is regarded as having initiated the eudaimonistic ethical tradition, the present volume looks at Plato, Aristotle, the Skeptics, Seneca [Stoicism], Epicurus, Plotinus (...) [neo-Platonism], Augustine, Boethius, Anselm, and ends with Abelard, the final major figure in early medieval philosophy. Special efforts are made to reveal and trace the continuity and development of the views on rationality and happiness among these major thinkers within this period. The book's approach is historical, but the topics it treats are relevant to many discussions pursued in contemporary philosophical circles. Specifically, the book aims to make two major contributions to the ongoing development of virtue ethics. First, contemporary virtue ethics often draws distinctions between ancient Greek ethics and modern moral philosophy [mainly utilitarianism and Kantianism], and seeks to model ethics on ancient ethics. In doing so, however, contemporary virtue ethics often ignores the transition from Greek ethics to the early Latin medieval tradition. Second, contemporary virtue-based ethics, in its efforts to seek insights from ancient ethics, centers on virtue. In contrast, in ancient and medieval ethics, virtue is pursued for the sake of happiness [eudaimonia], and virtue is conceived as excellence of rationality. Hence, the relationship between rationality and happiness provides the framework for ethical inquiry within which the discussion of virtue takes place.

The impact of Nietzsche's engagement with the Greek skeptics has never before been systematically explored in a book-length work - an inattention that belies the interpretive weight scholars otherwise attribute to his early career as a professor of classical philology and to the fascination with Greek literature and culture that persisted throughout his productive academic life. Jessica N. Berry fills this gap in the literature on Nietzsche by demonstrating how an understanding of the Pyrrhonian skeptical tradition illuminates Nietzsche's own reflections (...) on truth, knowledge, and ultimately, the nature and value of philosophic inquiry. This entirely new reading of Nietzsche's epistemological and ethical views promises to make clear and render coherent his provocative but often opaque remarks on the topics of truth and knowledge and to grant us further insight into his ethics-since the Greek skeptics, like Nietzsche, take up the position they do as a means of promoting well-being and psychological health. In addition, it allows us to recover a portrait of Nietzsche as a philologist and philosophical psychologist that has been too often obscured by commentaries on his thought. "The book addresses a number of central issues in Nietzsche's philosophy, including perspectivism and his conception of truth. The idea that his views in these areas owe much to the ancient Pyrrhonists casts them in an important new light, and is well supported by the texts. A lot of people from a lot of different areas in philosophy will have good reason to take notice." - Richard Bett, Johns Hopkins University. (shrink)

We are sceptical of concerns over the opacity of algorithmic decision tools. While transparency and explainability are certainly important desiderata in algorithmic governance, we worry that automated decision-making is being held to an unrealistically high standard, possibly owing to an unrealistically high estimate of the degree of transparency attainable from human decision-makers. In this paper, we review evidence demonstrating that much human decision-making is fraught with transparency problems, show in what respects AI fares little worse or better and argue that (...) at least some regulatory proposals for explainable AI could end up setting the bar higher than is necessary or indeed helpful. The demands of practical reason require the justification of action to be pitched at the level of practical reason. Decision tools that support or supplant practical reasoning should not be expected to aim higher than this. We cast this desideratum in terms of Daniel Dennett’s theory of the “intentional stance” and argue that since the justification of action for human purposes takes the form of intentional stance explanation, the justification of algorithmic decisions should take the same form. In practice, this means that the sorts of explanations for algorithmic decisions that are analogous to intentional stance explanations should be preferred over ones that aim at the architectural innards of a decision tool.

The purpose of this book is to give a coherent account of the different perspectives on science and technology that are normally studied under various disciplinary heads such as philosophy of science, sociology of science and science policy. It is intended for students embarking on courses in these subjects and assumes no special knowledge of any science. It is written in a direct and simple style, and technical language is introduced very sparingly. As various perspectives are sketched out in this (...) book, the reader moves towards a consistent conception of contemporary science as a rapidly changing social institution that has already grown out of its traditional forms and plays a central role in society at large. It will appeal to students in a wide range of scientific disciplines and complement well Professor Ziman's earlier books. (shrink)

Kant’s philosophy of science takes on sharp contour in terms of his interaction with the practicing life scientists of his day, particularly Johann Blumenbach and the latter’s student, Christoph Girtanner, who in 1796 attempted to synthesize the ideas of Kant and Blumenbach. Indeed, Kant’s engagement with the life sciences played a far more substantial role in his transcendental philosophy than has been recognized hitherto. The theory of epigenesis, especially in light of Kant’s famous analogy in the first Critique, posed crucial (...) questions regarding the ‘looseness of fit’ between the constitutive and the regulative in Kant’s theory of empirical law. A detailed examination of Kant’s struggle with epigenesis between 1784 and 1790 demonstrates his grave reservations about its hylozoist implications, leading to his even stronger insistence on the discrimination of constitutive from regulative uses of reason. The continuing relevance of these issues for Kant’s philosophy of science is clear from the work of Buchdahl and its contemporary reception. (shrink)

The danger of human operators devolving responsibility to machines and failing to detect cases where they fail has been recognised for many years by industrial psychologists and engineers studying the human operators of complex machines. We call it “the control problem”, understood as the tendency of the human within a human–machine control loop to become complacent, over-reliant or unduly diffident when faced with the outputs of a reliable autonomous system. While the control problem has been investigated for some time, up (...) to this point its manifestation in machine learning contexts has not received serious attention. This paper aims to fill that gap. We argue that, except in certain special circumstances, algorithmic decision tools should not be used in high-stakes or safety-critical decisions unless the systems concerned are significantly “better than human” in the relevant domain or subdomain of decision-making. More concretely, we recommend three strategies to address the control problem, the most promising of which involves a complementary coupling between highly proficient algorithmic tools and human agents working alongside one another. We also identify six key principles which all such human–machine systems should reflect in their design. These can serve as a framework both for assessing the viability of any such human–machine system as well as guiding the design and implementation of such systems generally. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy after ChristJohn O'CallaghanConsider the words of Justin Martyr written in the middle of the second century after the birth of Christ and after Justin's conversion to Christianity:Philosophy is indeed one's greatest possession, and is most precious in the sight of God, to whom it alone leads us and to whom it unites us, and in truth they who have applied themselves to philosophy are holy men.1In addition to (...) the praise heaped upon the philosophers, among whom Justin had counted himself before his conversion,2 the text is one of the earliest pieces of evidence for the historical reality of Christian intellectual engagement with pagan or secular philosophy. Whether that engagement proved spiritually fruitful or sterile in any particular age or any particular tradition of philosophy, Christian intellectuals have often sought out engagement with philosophy as an inherent task of the intellectual life of the Church, in order to pursue and develop the understanding of Christian revelation and the mode of life informed by it. One lasting result of the impetus represented by Justin is to be found even now in the normative requirement in Catholic education that, at a certain stage of development, anyone who receives a [End Page 49] serious Catholic education must be introduced to serious philosophical reflection on where we came from, what we are, and where we are born to go.In addition, one of the general points John Henry Newman made in The Idea of a University is that the human mind looks for unity in the diversity of intellectual disciplines it pursues. In search of this unity, it seeks a kind of primary discipline that takes into account the truths discovered throughout the other disciplines as it seeks to understand what it can of the whole of reality, not just its parts. But Newman also pointed out that, in the absence of such a unifying discipline, practitioners of each particular discipline will often claim for their particular discipline the prize of being primary—of being the discipline by which all others must be understood and judged.3Take classical and modern physics. A familiar claim of some physicists, but even more so of non-physicist physicalists, is that physics is the fundamental intellectual discipline for understanding what is real. All reality, living reality, historical reality, moral reality, indeed perhaps even literary reality, must be reduced to reality as described by the physicists or rejected as unreal or epiphenomenal, or in a kinder, gentler vein, non-reductively emergent and supervenient. Whichever position is taken, whether reduction, non-reductive emergence, or epiphenomenalism, the thought is that the real work of the really real is done by reality as described by physics, either in its actual contemporary state or, more likely, in an idealized future state always on the horizon of where physics presently is. We are really atoms spinning ceaselessly in the void, mostly empty space, the warp and woof of a four-dimensional space-time manifold, or congeries of strings in an even more bizarre thirteen-dimensional manifold, or whatever was said most recently to surpass what was said before that by the leading physicists in California or Cambridge.However, anyone who has actually practiced physics knows that, even when uttered by a physicist, these are not claims of physics, but about physics. What prompts them is the sense that there is no intellectual discipline other than contemporary physics itself that can both understand the achievements of physics and integrate them into a larger intellectual comprehension of reality as a whole. These claims about physics nicely display Newman's point about the way in which a particular discipline, in the absence of a larger more comprehensive discipline, can take on an importance for its practitioners well beyond its disciplinary limits. [End Page 50]In the case of physics, if a more comprehensive unifying discipline is not to be found, this attitude is not entirely unjustified, for Newman's point is partly Aristotelian. Aristotle had pointed out that, if one cannot show that unchangeable, and thus non-physical beings, exist, then what Aristotle called "first philosophy" would just be physics as he understood it, the science of...

At his death in 2010, the Anglo-American analytic philosopher John Haugeland left an unfinished manuscript summarizing his life-long engagement with Heidegger’s Being and Time. As illuminating as it is iconoclastic, Dasein Disclosed is not just Haugeland’s Heidegger—this sweeping reevaluation is a major contribution to philosophy in its own right.

In lieu of an abstract, here is a brief excerpt of the content:Are There Failed Persons?John O'CallaghanIntroductionAre there failed persons? Yes. However, before explaining what a failed person is, it will be good to consider closely a very significant part of our society to get a sense of what it thinks a failed person is, since my account of what a failed person is is markedly different. It is important to think about the question of failed persons because there (...) are growing movements here and abroad aimed at killing by medical means human beings who are judged in some sense to be failed persons, human beings who do not count as persons according to a common societal notion of persons, a social-psychological notion of persons.The question for anyone who lives within this society with its notion of failed persons is whether one will take part in and support this movement toward killing human beings or avoid it, indeed whether one will push back against it. It is easy enough to fall into a trap of thinking about failed persons the way much of our society does. One's complicity in adopting the social-psychological notion of person contributes to enabling the acceptance of such killing, even if one believes one would never perform the killing act. My effort here is precisely to push back against such killing, by pushing back against the notion of persons that animates it.The killing of human beings by our society is not simply confined to abortion, as it has been legally and widely available here in the United States for almost fifty years now. Recent political discussions in the wake of the Dobbs decision have made it clear that many political leaders think such killing ought to be allowed all the way up until birth, and perhaps after. Relatively [End Page 1123] recently there was an article in a mainstream bioethics journal by Alberto Giubilini and Francesca Minerva arguing that what most people would take to be cases of infanticide should be renamed, per their title, "After-Birth Abortion."1 The article was not about the moral legitimacy of either infanticide or abortion. The moral legitimacy of those acts for various reasons was taken as a given by the authors. In the case of euthanizing infants, they noted the expanding number of arguments for it among philosophers, the desire for guidelines for doing it among members of the medical profession, and the protocols for it established in places like the Netherlands.The authors argued that in the case of newborns, including healthy newborns, killing them should not be considered infanticide or euthanasia.2 They distinguished abortion from both euthanasia and infanticide. Euthanasia involves killing a human person, where a person is understood to be a being that can experience itself as having interests that can be harmed. "We take 'person' to mean an individual who is capable of attributing to her own existence some (at least) basic value such that being deprived of this existence represents a loss to her."3 Euthanasia, when justified, is justified by being in the best "interests" of the person killed. Infanticide involves euthanizing children.However, the authors claim that a newborn is not a person in the sense of "person" specified. So, the authors' term "after-birth abortion" is a terminological distinction based upon denying that a newborn is a child, children being persons. They also assume that infants are children as they understand "child." So not being a child, a newborn cannot be an infant. Not being an infant, killing it cannot be infanticide or euthanasia, again as the authors define those terms.4 Instead, killing the newborns, healthy or not, should be thought of as having the same moral weight as an abortion before birth, and thus rather than being called infanticide or euthanasia, it should be called "after-birth abortion."5Killing a newborn then is "ethically permissible" in just the same circumstances and for the same reasons as abortion is ethically permissible. Among [End Page 1124] the "ethically permissible" circumstances for killing newborns, including perfectly healthy newborns, are that the "well-being of the family is at risk" with respect to "social, psychological, economic" factors,6 but also the fact...

The earliest writer who deserves to be called a psychologist is Hobbes; and if we consider the time when he wrote, we cannot fail to be surprised at what I may term his prevision of the most important results which have now been established by science. He was the first clearly to sound the note which has ever since constituted the bass, or fundamental tone, of scientific thought. Let us listen to it through the clear instrumentality of his own language:-.

The leading hypothesis concerning the “reuse” or “recycling” of neural circuits builds on the assumption that evolution might prefer the redeployment of established circuits over the development of new ones. What conception of cognitive architecture can survive the evidence for this hypothesis? In particular, what sorts of “modules” are compatible with this evidence? I argue that the only likely candidates will, in effect, be the columns which Vernon Mountcastle originally hypothesized some 60 years ago, and which form part of the (...) well-known columnar hypothesis in neuroscience—systems that cannot handle gross cognitive functions as distinct from strictly exiguous subfunctions. This is in stark contrast to the modules postulated by much of cognitive psychology, cognitive neuropsychology, and evolutionary psychology. And yet the fate of this revised notion is unclear. The main issue confronting it is the effect of the neural network context on local function. At some point the effects of context are so strong that the degree of specialization required for modularity is not able to be met. Still, despite indications from neuroimaging that peripheral and central systems deploy shared circuitry, some skills clearly do seem to display modularization and autonomy. This article: provides an in-depth analytical and historical review of the fortunes of modular thinking in cognitive science; offers a systematic calibration of brain regions in terms of degrees of functional specificity and robustness; and suggests another way of accounting for the partially encapsulated character of expertise and other highly practiced skills without having to resort to domain-specific modules.

The past two decades have witnessed a revival of interest in multiple realization and multiply realized kinds. Bechtel and Mundale’s (1999) illuminating discussion of the subject must no doubt be credited with having generated much of this renewed interest. Among other virtues, their paper expresses what seems to be an important insight about multiple realization: that unless we keep a consistent grain across realized and realizing kinds, claims alleging the multiple realization of psychological kinds are vulnerable to refutation. In this (...) paper I argue that, intuitions notwithstanding, the terms of their recommendation make it impossible to follow, while also misleadingly insinuating that its application virtually guarantees mind-brain identity. Instead of a matching of grains, what multiple realization really requires is a principled method for adjudicating upon differences between tokens. Shapiro’s (2000) work on multiple realization can be understood as an attempt to adumbrate just such a method. While his “causal relevance” criterion can easily be mistaken for Bechtel and Mundale’s grain requirement, my analysis reveals exactly where and why these two tests diverge. (shrink)

Modularity is a fundamental doctrine in the cognitive sciences. It holds a preeminent position in cognitive psychology and generative linguistics, as well as a long history in neurophysiology, with roots going all the way back to the early nineteenth century. But a mature field of neuroscience is a comparatively recent phenomenon and has challenged orthodox conceptions of the modular mind. One way of accommodating modularity within the new framework suggested by these developments is to go for increasingly soft versions of (...) modularity. One such version, which I call the “system” view, is so soft that it promises to meet practically any challenge neuroscience can throw at it. In this paper, I reconsider afresh what we ought to regard as the sine qua non of modularity and offer a few arguments against the view that an insipid “system” module could be the legitimate successor of the traditional notion.

We develop an account of societal democratization that synthesizes cultural sociology and deliberative democracy. Cultural sociologists emphasize the symbolic inclusion of marginalized groups into the civil sphere. Deliberative democrats stress growth in the deliberative capacity of society. We argue that democratization entails the co-evolution of culture and reason. The basis of co-evolution is the performative construction of an inclusive demos, which requires a deliberative background but is also a source of the moral emotions that motivate deliberation. Since moral emotions can (...) also sweep people up and make them do reckless things, they must in turn be redeemable in inclusive deliberation. This synthesis sharpens a normative position for the evaluation of episodes of inclusion, extends current accounts of the place of emotion in cultural sociology and deliberative democracy, and provides a frame for comparative analyses of democratization. We illustrate with an examination of the exclusion and inclusion of Indigenous Australians. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:JOSEPH MARGOLIS THE LOGIC AND STRUCTURES OF FICTIONAL NARRATIVE The fascination of fiction and narrative is plainly immense, sind current analyses are notably fresh and ingenious. But ifone were to venture a compendious account of die most strategic conceptual claims bearing on those notions, they might well be captured by the following three theses: (i) that fiction and narrative are logically quite distinct, without necessarily excluding one anodier; (ii) (...) that fictional worlds are no worlds at all; they are merely imagined to exist; and (iii) that events, whether actual or imagined, cannot be specified independently of the categories by which we identify them as the events they are, categories subject to change over time. What is intriguing about mese three claims is that they strike the ear as utterly commonplace and obvious. But that is dieir strength. For it would be a great convenience if the relevant puzzles generated by analytic philosophy, hermeneutics, the new narratology, semiotics and the like could be resolved, convincingly, by appeal to die implications of these diree homely trudis. In addition, diey affect one another in a rather complicated way, and, taken joindy, easily expose certain influential false starts. The import of (iii), for example, is notably ignored in die otherwise powerful analysis of narrative afforded by Gérard Genette. Its bearing on (i) utterly undermines the explicit dualism favored by Seymour Chatman, who is clearly influenced by Genette himself. The failure to mark die force of (i) and its analogue regarding poetry is most obvious in I. A. Richards's contrast between poetry and science, the work of the Prague circle, Northrop Frye's Anatomy of Criticism, and such recent speech-act theories of poetry and fiction as those proposed by Richard Ohmann, Monroe Beardsley, and Mary Louise Pratt. The corresponding failure widi respect to (ii) is clear in John Searle's theory of reference and in die ontological claims made by Nicholas Wolterstorff. The connection between (i) and (ii) is muddled most famously by G. E. Moore. These charges suggest die quarrelsome promise of the intended economy. But, as we shall see, they also lead in the direction of a more constructive theory of texts and their interpretation and of die constraints of narrative and style diat affect fiction. 162 Joseph Margolis163 Fiction, we say, differs from reality as well as from legend. But in speaking thus, we betray an understandable confidence that these three kinds of"world"— or, these three worlds — are conceptually well-behaved and open to straightforward demarcation. Once more, we slip altogether too easily between talking about certain worlds and about the narrative accounts by which we do so. What distinguishes fictional reference? we ask, and what is a fictional world? The best way to proceed here is to begin with strong intuitions and to trace dieir systematic consequences in order to test how far they are unassailable — or whether and where they must yield to others that are more accommodating. One particularly promising equivocation is the following. We speak of fictional worlds as possible (but not actual) worlds; but even if what is possible in a fictional world corresponds (in some sense) to what is possible in the actual world, it is not, as such, a possibility of or at the actual world. The "possible worlds" idiom is fundamentally and doubly equivocal. For, a "possible world" signifies either what is merely logically or conceptually compossible, or what (under suitably referential, predicative, causal, and similar constraints) is compossible specifically with respect to the actual world (or some part of it). Certainly, Balzac's La Cousine Bette "presents" an imaginary world that is internally coherent and compossible. One might even say, ignoring its fictive nature, diat such a world — or events very much like those of the story — is compossible with a certain portion of the actual world of nineteenth-century France. But Lewis Carroll's Alice in Wonderfond, though it scrupulously presents a coherent world of compossible events, does not present a world compossible with the actual world. And, on certain views at least, Thomas Mann's The Transposed Heads presents a possible world that is a conceptual impossibility. There is, however, no need to quarrel about particular cases...

Derek Parfit takes an externalist and cognitivist view about normative reasons. I shall explore this view and add some arguments that support it. But I shall also raise a doubt about it at the end.

There is relatively little literature on Indian skepticism, with hardly any monograph on the subject comparable to, e.g., Julia Annas’ and Jonathan Barnes’ The Modes of Scepticism: Ancient Texts and Modern Interpretations, R.J. Hankinson’s The Sceptics: The Arguments of the Philosophers, a series of Richard H. Popkin’s monographs on the history of skepticism, or two recent competing volumes as collective efforts: The Oxford Handbook of Skepticism edited by John Greco and The Cambridge Companion to Ancient Scepticism edited by Richard (...)

Evidence of the pervasiveness of neural reuse in the human brain has forced a revision of the standard conception of modularity in the cognitive sciences. One persistent line of argument against such revision, however, cites the evidence of cognitive dissociations. While this article takes the dissociations seriously, it contends that the traditional modular account is not the best explanation. The key to the puzzle is neural redundancy. The article offers both a philosophical analysis of the relation between reuse and redundancy (...) as well as a plausible solution to the problem of dissociations. (shrink)

The conflict between Kant and the medical faculty was far more complex and substantial than is indicated in the section of his famous Conflict of the Faculties addressing this matter. In this essay I will consider not only what Kant, as a philoso­pher, thought of medicine as a faculty, but what medicine as a faculty thought of Kant as a philosopher.
