In our paper, “The Free-Will Intuitions Scale and the question of natural compatibilism” , we seek to advance empirical debates about free will by measuring the relevant folk intuitions using the scale methodology of psychology, as a supplement to standard experimental methods. Stephen Morris raises a number of concerns about our paper. Here, we respond to Morris's concerns.

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Philosophy 38.1 (2000) 103-110 [Access article in PDF] Hutcheson's Moral Sense and the Problem of Innateness Daniel Carey National University of Ireland Francis Hutcheson's philosophy arguably represented a delicate, and at times precarious, synthesis of positions laid out by John Locke and the third Earl of Shaftesbury. From Shaftesbury, whose influence he acknowledged explicitly in the title page of the first edition of (...) the Inquiry into the Original of our Ideas of Beauty and Virtue (1725), Hutcheson gained an appreciation of the dignity of human nature, reflected in sociable instincts, benevolent impulses, and the moral sense. From Locke he adopted the bias of empiricism, placing moral philosophy on an observational footing, ostensibly free from a priori assumptions.1 The challenge posed by integrating the work of these two mentors arose from their deep incompatibility, evident in Shaftesbury's declared opposition to Locke's mode of philosophizing and rejection of his disagreeable representation of human nature. Nowhere was Hutcheson's combination of Locke and Shaftesbury more difficult to sustain than over the issue of innateness. Locke was intent on jettisoning innate ideas, but Shaftesbury remained keen to rescue them.Of course there are different versions and definitions of innateness at stake here: on one account, it entailed the possession of particular, specifiable ideas or conceptions, somehow inscribed in the soul which might or might not require the trigger of experience to emerge (for example, ideas of God, good and, evil); on another, a predisposition to hold certain beliefs and make certain judgments, provided that 'normal' conditions of maturity and rationality have been met; finally, a faculty, that is, an inborn structure enabling the subject to experience the world in a moral way, and to register ethical responses to it, whatever they may be.2 All of these orientations on innateness impinge on Hutcheson's approach to the problem. On the one hand, he conceded Locke's critique as consistent with modern philosophizing, but he restricted its force to innate ideas or propositions, leaving the moral sense conveniently exempt from the [End Page 103] objection. On the other hand, Hutcheson was determined to reintroduce the content of innate ideas if not the name, assigning the moral sense a familiar, normative role in underwriting perceptions and judgments.The intricacy of the issue has led critics to arrive at contradictory assessments of Hutcheson's outlook on innateness. Stephen Buckle and Knud Haakonssen take Hutcheson at his word and argue that he abandoned innate ideas altogether.3 David Fate Norton agrees that Hutcheson found Locke's critique persuasive, at least against neo-Platonic theories of ethics (such as Cudworth's), but elsewhere Norton maintains that Hutcheson sets up the moral sense as an "innate and independent" moral faculty.4 Charles Taylor, meanwhile, stresses the dispositional inclination of Hutcheson's argument: "Goodness and generosity are natural to us. He might have been tempted in an earlier generation to say 'innate,' but he has internalized enough of the Lockean psychology to shy away from this. So he claims that these sentiments are ones we naturally grow to have, just as we develop to our normal stature and shape."5 Given the disparate of conclusions drawn by historians of philosophy, the issue clearly merits reinvestigation. Differing lines of interpretation have emerged precisely because Hutcheson frequently changed his tack. His shifting strategy appears both in the revisions he made to later editions of the Inquiry, and in the development of his work over the course of his career. Closer attention to these considerations offers an insight into the predicament of moral philosophy in the early decades of the eighteenth century.In the critique of innate practical ideas launched in the first book of the Essay concerning Human Understanding (1690), Locke took a sceptical view of Stoic assertions about human uniformity and the existence of "common notions" indicating moral consensus around the world.6 Evidence drawn from contemporary travelers suggested the absence of any moral agreement of this kind; Locke based his conclusion on an investigation of human practice influenced by techniques...

n 1902, 70 million years after it tripped lightly through the Mesozoic forests in search of meat, the skeleton of a 20-foothightyrannosaurus was dynamited out of a sandstone bluff near Hell Creek, Mont. Wrapped in burlap and plaster and shipped back to New York, the bones were painstakingly reassembled by fossil curator Barnum Brown of the American Museum of Natural History. It was there, one day in 1947, that they happened to scare the bejesus out of 5-year-old Stephen Jay (...) Gould. With a mouthful of teeth as big as bananas, the great reptile gaped down at the little mammal who had usurped its place at the head of the food chain and set him scurrying for the safety of his daddy's pant leg. It was a sublime epiphany. Long after Gould could stare with equanimity at the skull of tyrannosaurus, he was left with the essential mystery that still motivates him as perhaps America's foremost writer and thinker on evolution: why should dinosaurs have ended up in human museums instead of—as one among an infinite number of evolutionary possibilities—the other way around?

The title is unashamedly plagiarized from Stephen Todd's excellent book, The Shape of Athenian Law. The plagiarism is slightly misleading, however, since my interest is in law as enactment while Todd's title expresses his interest in law as system . The issue I wish to address is the formulation of written laws in Athens during the late archaic and classical period, specifically the balance between procedural and substantive law. Substantive law deals with rights, obligations, offences, etc. Its role is (...) to define behaviour which is required, allowed, or prohibited. These are what Hart terms ‘primary rules’. Procedural law, on the other hand, deals, as the name suggests, with the administration of justice, that is with jurisdiction, process, etc. Hart's term for these is ‘secondary rules’. The two cannot be separated quite as neatly as I have suggested, of course. A procedural law can scarcely avoid mentioning the offences or rights whose punishment or protection it regulates, while a substantive law may need to address issues such as jurisdiction. This is therefore an issue of orientation, not a simple binary division. However, as a broad basis for classification it is of value. (shrink)

The increasing global demand for energy necessitates devoted attention to the formulation and exploration of mechanisms of thermal heat exchangers to explore and save heat energy. Thus, innovative thermal transport fluids require to boost thermal conductivity and heat flow features to upsurge convection heat rate, and nanofluids have been effectively employed as standard heat transfer fluids. With such intention, herein, we formulated and developed the constitutive flow laws by utilizing the Rossland diffusion approximation and Stephen’s law along with the (...) MHD effect. The mathematical formulation is based on boundary layer theory pioneered by Prandtl. Governing nonlinear partial differential flow equations are changed to ODEs via the implementation of the similarity variables. A well-known computational algorithm BVPh2 has been utilized for the solution of the nonlinear system of ODEs. The consequence of innumerable physical parameters on flow field, thermal distribution, and solutal field, such as magnetic field, Lewis number, velocity parameter, Prandtl number, drag force, Nusselt number, and Sherwood number, is plotted via graphs. Finally, numerical consequences are compared with the homotopic solution as a limiting case, and an exceptional agreement is found. (shrink)

This article argues that inquirers should adopt an active orientation to the limits of their knowledge, an approach referred to as “Transformational Fallibilism”. Drawing on the Popperian tradition, this approach treats the fallibility of knowledge as more than a philosophical nicety, rather seeing the questioning of claims, including those that have been successful, as a key way to improve the understandings of inquirers. This is illustrated with reference to the example of Newtonian and Einsteinian understandings of gravity and time in (...) the natural sciences, and debates about the role of fathers in child-rearing in the social sciences. I compare this approach to that found within critical realism, arguing that while defenders of the latter acknowledge fallibility to some extent, certain of their arguments also place problematic limits on it. Examining Sayer’s work, I argue that his view that practically successful understandings reveal something about the structure of the world involves an overconfidence in these understandings. I suggest that Elder-Vass’s use of the idea of approximate truth involves a similar difficulty. By contrast, I argue for the importance of treating all elements of the understanding, including those bound up with practical successes, as potentially in need of reconstruction at any point.

In “The Free-Will Intuitions Scale and the Question of Natural Compatibilism,” Deery, Davis, and Carey recommend that experimental philosophers employ a new methodology for determining the extent to which the folk are natural compatibilists about free will and moral responsibility. While I agree that the general methodology that the authors developed holds great promise for improving our understanding of folk attitudes about free will and moral responsibility, I am much less enthusiastic about some of the conclusions that they reached (...) on the basis of the particular studies they ran. Key among these are that the folk harbor some compatibilist intuitions and that the findings of both Nichols and Knobe , on the one hand, and Nahmias and Murray , on the other, are undermined by their reliance upon a particular formulation of determinism in the cases they presented to their subjects.

This article explores the difficulties raised for social scientific investigation by the absence of experiment, critically reviewing realist responses to the problem such as those offered by Bhaskar, Collier and Sayer. It suggests that realist arguments for a shift from prediction to explanation, the use of abstraction, and reliance upon interpretive forms of investigation fail to demonstrate that these approaches compensate for the lack of experimental control. Instead, it is argued that the search for regularities, when suitably conceived, provides the (...) best alternative to experiment for the social sciences. (shrink)

Creations of the Mind presents sixteen original essays by theorists from a wide variety of disciplines who have a shared interest in the nature of artifacts and their implications for the human mind. All the papers are written specially for this volume, and they cover a broad range of topics concerned with the metaphysics of artifacts, our concepts of artifacts and the categories that they represent, the emergence of an understanding of artifacts in infants' cognitive development, as well as the (...) evolution of artifacts and the use of tools by non-human animals. This volume will be a fascinating resource for philosophers, cognitive scientists, and psychologists, and the starting point for future research in the study of artifacts and their role in human understanding, development, and behaviour.Contributors: John R.

This article is a commentary on Carey (2009) The Origin of Concepts. Carey rightly rejects the building blocks model of concept acquisition on the grounds that new primitive concepts can be learned via the process of bootstrapping. But new primitives can be learned by other acquisition processes that do not involve bootstrapping, and bootstrapping itself is not a unitary process. Nonetheless, the processes associated with bootstrapping provide important insights into conceptual change.

Postmodernism has evoked great controversy and it continues to do so today, as it disseminates into general discourse. Some see its principles, such as its fundamental resistance to metanarratives, as frighteningly disruptive, while a growing number are reaping the benefits of its innovative perspective. In Political Theory and Postmodernism, Stephen K. White outlines a path through the postmodern problematic by distinguishing two distinct ways of thinking about the meaning of responsibility, one prevalent in modern and the other in postmodern (...) perspectives. Using this as a guide, White explores the work of Heidegger, Foucault, Derrida, Lyotard, and Habermas, as well as 'difference' feminists, with the goal of showing how postmodernism can inform contemporary ethical-political reflection. In his concluding chapter, White examines how this revisioned postmodern perspective might bear on our thinking about justice. (shrink)

Mental causes are threatened from two directions: from below, since they would appear to be screened off by lower-order, e.g., neural states; and from within, since they would also appear to be screened off by intrinsic, e.g., syntactical states. A principle needed to parry the first threat -causes should be proportional to their effects- appears to leave us open to the second; for why should unneeded extrinsic detail be any less offensive to proportionality than excess microstructure? I say that the (...) second threat relies on a perversion of proportionality that would lay waste to all causal relations. (shrink)

[Stephen Yablo] The usual charge against Carnap's internal/external distinction is one of 'guilt by association with analytic/synthetic'. But it can be freed of this association, to become the distinction between statements made within make-believe games and those made outside them-or, rather, a special case of it with some claim to be called the metaphorical/literal distinction. Not even Quine considers figurative speech committal, so this turns the tables somewhat. To determine our ontological commitments, we have to ferret out all traces (...) of nonliterality in our assertions; if there is no sensible project of doing that, there is no sensible project of Quinean ontology. /// [Andre Gallois] I discuss Steve Yablo's defence of Carnap's distinction between internal and external questions.

In the third section I say why Carnap's application of the distinction between internal and external questions runs into trouble.

Despite holding that all concepts are strictly speaking innate, Leibniz attempts to accommodate the common belief that at least some concepts are adventitious by appealing to his theory of ideal action. The essential idea is that an innate concept can be considered adventitious, in a sense, just in case its ideal cause is to be found outside the mind of the one who possesses the concept. I explore this attempt at accommodation and argue that it fails. [See external link for (...) English draft.]. (shrink)

I examine the (mediated) correspondence between Spinoza and Robert Boyle concerning the latter’s account of fluidity and his experiments on reconstitution of niter in the light of the epistemology and doctrine of method contained in the Treatise on the Emendation of the Intellect. I argue that both the Treatise and the correspondence reveal that for Spinoza, the proper method of science is not experimental, and that he accepted a powerful under-determination thesis. I argue that, in contrast to modern versions, Spinoza’s (...) form of naturalism was a highly rationalist and anti-empirical one. I conclude with a brief account of the value of experience and experimentation for Spinoza’s scientific method. (shrink)

Substantial efforts have recently been made to reform the physician-patient relationship, particularly toward replacing the `silent world of doctor and patient' with informed patient participation in medical decision-making. This 'new ethos of patient autonomy' has especially insisted on the routine provision of informed consent for all medical interventions. Stronly supported by most bioethicists and the law, as well as more popular writings and expectations, it still seems clear that informed consent has, at best, been received in a lukewarm fashion by (...) most clinicians, many simply rejecting what they commonly refer to as the `myth of informed consent'. The purpose of this book is to defuse this seemingly intractable controversy by offering an efficient and effective operational model of informed consent. This goal is pursued first by reviewing and evaluating, in detail, the agendas, arguments, and supporting materials of its proponents and detractors. A comprehensive review of empirical studies of informed consent is provided, as well as a detailed reflection on the common clinician experience with attempts at informed consent and the exercise of autonomy by patients. In the end, informed consent is recast as a management tool for pursuing clinically and ethically important goods and values that any clinician should see as meriting pursuit. Concurrently, the model incorporates a flexible, anticipatory approach that recognizes that no static, generic ritual can legitimately pursue the quite variable goods and values that may be at stake with different patients in different situations. Finally, efficiency of provision is addressed by not pursuing the unattainable and ancillary. Throughout, the traditional principle of beneficence is appealed to toward articulating an operational model of informed consent as an intervention that is likely to change outcomes at the bedside for the better.

Kant is often regarded as one of the founding fathers of modern liberal democracy. His political theory reaches its climax in the ground-breaking work, Perpetual Peace (1795), which sets out the basic framework for a world federation of states united by a system of international law. What is less well known is that two years earlier, in his Religion within the Bounds of Bare Reason (1793/1794), Kant had postulated a very different, explicitly religious path to the politics of peace: he (...) presents the idea of an “ethical community” as a necessary requirement for humanity to become “satisfactory to God”. While many recent scholars have noted the importance of Kant’s concept of the ethical community, few recognize the force of his argument that such a community is possible only if it takes the form of a church; as a result, the precise status of his proposal remains unclear and under-appreciated. He argues in Division One, Section IV, of Religion’s Third Piece that the idea of this community can become a reality only through a “church” that is characterized by four rational requirements: unity, integrity, freedom, and the changeability of all church rules except these four unchangeable marks. Prior to Section IV, Division One portrays this ethical community as having a political form, yet an essentially nonpolitical matter. He compares it with Jewish theocracy, but observes that the latter failed to be an ethical commonwealth because it was explicitly political. Whereas traditional theocracy replaces the political state of nature (which conforms to the law, “might makes right”) with an ethical state of nature (which conforms to the law that I call, “should makes good”), or attempts to synthesize them, non-coercive theocracy transcends this distinction through a new perspective: it unites humanity in a common vision of a divine legislator whose only law is inward, binding church members together like families, through the law of love. Whereas the legal rights supported by democracy and a system of international law can go a long way to prepare for world peace, Kant’s conviction is that it will be ultimately impossible without support from healthy religion.

Can normative words like "good," "ought," and "reason" be defined in non-normative terms?

Stephen Mumford puts forward a new theory of dispositions, showing how central their role is in metaphysics and philosophy of science. Much of our understanding of the physical and psychological world is expressed in terms of dispositional properties--from the solubility of sugar to the belief that zebras have stripes. Mumford discusses what it means to say that something has a property of this kind, and how dispositions can possibly be real things in the world. His clear, straightforward, realist account (...) reveals them to be less mysterious than they seem, and shows that an understanding of dispositions is essential to an understanding of properties, causation, and scientific laws.

This book develops a theory of how the imagination functions, and how it evolved. The imagination is characterized as an embodied cognitive system. The system draws upon sensory-motor, visual, and linguistic capacities, but it is a flexible, developmental ability, typified by creative improvisation. The imagination is a voluntary simulation system that draws on perceptual, emotional, and conceptual elements, for the purpose of creating works that adaptively investigate external (environmental) and internal (psychological) resources. Beyond the adaptive useful values of this system, (...) imagination also possesses significant intrinsic value (e.g., in the joy of play, and states of wonder). The book argues that imagination is not a late arrival in the evolution of mind, but one of the earliest human abilities. (shrink)

Confucian political philosophy has recently emerged as a vibrant area of thought both in China and around the globe. This book provides an accessible introduction to the main perspectives and topics being debated today, and shows why Progressive Confucianism is a particularly promising approach. Students of political theory or contemporary politics will learn that far from being confined to a museum, contemporary Confucianism is both responding to current challenges and offering insights from which we can all learn. The Progressive Confucianism (...) defended here takes key ideas of the twentieth-century Confucian philosopher Mou Zongsan as its point of departure for exploring issues like political authority and legitimacy, the rule of law, human rights, civility, and social justice. The result is anti-authoritarian without abandoning the ideas of virtue and harmony; it preserves the key values Confucians find in ritual and hierarchy without giving in to oppression or domination. A central goal of the book is to present Progressive Confucianism in such a way as to make its insights manifest to non-Confucians, be they philosophers or simply citizens interested in the potential contributions of Chinese thinking to our emerging, shared world.

In this work, which has survived only in manuscript form and in Italian, Gardiner analyses the great dynastic changes in England's past in order to provide Phillip II with a guide to ruling England and establishing a Catholic dynasty. Gardiner's work is perhaps the clearest example of an attempt to relate Machiavelli's political theories to practical political problems.

The article presents a figurational sociological perspective on the recent history of the discipline of economics in the wake of the global financial crisis or ‘Great Recession’ that began in 2007–8. It is argued that the orthodox mainstream of economics has provided ideological cover for abstract individualism, for short-term greed, and for the denial of the wider social responsibilities of business and finance. The faith in ‘free markets’ has been associated with a blindness to power relationships and an indifference to (...) economic inequality. Orthodox economics is congruent with the mythical American Dream. The article draws upon the writings of Norbert Elias to reflect upon economics, and then in turn uses those reflections to raise some questions about Elias’s theories, particularly his ideas concerning functional democratization and increasing pressures towards more habitual foresight.

In this book, Stephen Acreman follows the development and reception of a hitherto under-analyzed concept central to modern and postmodern political theory: the Kantian ein erweiterte Denkungsart, or enlarged mentality. -/- While the enlarged mentality plays a major role in a number of key texts underpinning contemporary democratic theory, including works by Arendt, Gadamer, Habermas, and Lyotard, this is the first in-depth study of the concept encompassing and bringing together its full range of expressions. A number of attempts to (...) place the enlarged mentality at the service of particular ideals–the politics of empathy, of consensus, of agonistic contest, or of moral righteousness–are challenged and redirected. In its exploration of the enlarged mentality, the book asks what it means to assume a properly political stance, and, in giving as the answer ‘facing reality together’, it uncovers a political theory attentive to the facts and events that concern us, and uniquely well suited to the ecological politics of our time.

This issue of the Journal contains the material on physical mediumship originally scheduled for the Spring JSE. The plan for that issue had been to focus on the Felix Experimental Group (FEG) and its medium Kai Mügge, and Michael Nahm and I had each written very long papers describing and evaluating our detailed and extensive investigations of the group. But as I mentioned in my Editorial in the last issue, JSE 28:1 (Spring 2014), as we were preparing to send the (...) Spring issue to the printers, convincing evidence of fraud surfaced in the case, and the current issue now contains substantial revisions of those two long papers, reflecting what Nahm and I have learned and concluded in the interim. But first, since some (maybe many) JSE readers lack the background to put these contemporary investigations of physical mediumship into context, a few words on the subject are perhaps in order. As regular readers of our Historical Perspectives papers will know, physical mediumship flourished during a roughly 80-year period beginning in the mid-nineteenth century. The widespread emergence of physical mediums corresponded to the beginning, and then the heyday, of the Spiritualist movement, which began in the United States in the 1850s, and spread quickly to Europe. Spiritualism in the West fostered a more secular spiritism-the view that personal consciousness persists after bodily death, and that although some people are especially gifted mediumistically the rest of humanity can also experience a direct connection to "the other side." While mental mediums claimed to deliver messages from the deceased, say through automatic writing or trance impersonations, physical mediums purported to provide evidence of survival in various physical forms. The most common of these were "raps" or knocking sounds, either in the séance table or elsewhere in the room, typically answering "yes" or "no" questions by the number of sounds (e.g., two for "yes" and three for "no"). Sometimes, instead of raps, the séance table would tilt up and down several times, and in more dramatic cases the table would levitate fully. And in the most dramatic of those cases, sitters would report that the table carried people up and around the room with them, and many reported that they were unable to move the levitated table back to the floor once it was aloft. More dramatically still, many mediums purported to materialize objects resembling the deceased-for example, a disembodied hand and wrist (perhaps with characteristic deformations), or an image of the deceased's face, or a full-figure materialized human form. Although most spiritists insisted throughout that these physical phenomena were manifestations of the deceased mediated by the living, many investigators entertained and then gradually accepted the view that the carefully controlled (and presumably non-fraudulent) phenomena were actually psychokinetic productions of the living. Undoubtedly, many factors contributed to the decline of the Spiritualist movement and the apparent retreat of physical mediums to relatively inconspicuous enclaves or sitter groups. Not surprisingly, one of those is the richly documented history of mediumistic fraud perpetrated by soundrels only too willing to take advantage of grieving and gullible sitters. Nevertheless, and contrary to what many like to claim, it would be a mistake to think either that all physical mediums were frauds or that nobody managed to weed out the charlatans among them. First of all, investigators exposed many hundreds of fraudulent mediums during the late nineteenth and early twentieth centuries. Some of those investigators were self-styled skeptical debunkers-scientists or laypersons who made reputations for themselves by exposing mediumistic duplicity, and most of whom believed that spiritualistic phenomena simply couldn't be genuine. But others combined careful and critical research with a sympathetic or at least open-minded attitude toward the paranormal. One of the reasons this period is so important is that some physical mediums clearly stood out from the crowd. No matter how carefully they were controlled, and no matter how alert, competent, and familiar with conjuring were their investigators, these mediums produced effects that couldn't plausibly be dismissed as fraudulent or attributed to malobservation. In fact, one of the strongest bodies of evidence comes from the 1908 Naples sittings with Eusapia Palladino. Eusapia's three investigators were England's most experienced debunkers of fraudulent mediums. They knew the tricks of the trade (indeed, two of them were skilled conjurors); they knew what Eusapia's sometimes suspicious methods (and occasionally outright but simplistic tricks) were; they knew how to control for them; and the phenomena occurred in decent electric light and often at a distance from the medium. The investigators traveled to Naples believing they would establish once and for all that Eusapia was nothing but a trickster, and they left Naples grudgingly convinced that the nearly 500 phenomena they documented over eleven séances were not fraudulent.

What is the role of empirical tests in the evaluation of theories?This paper focuses on a narrowly-defined question: in judging theories, do scientists give greater weight (other things being equal) to successfulnovel predictionsthan to successful deductions of previously-known facts? The affirmative answer is called the “predictivist thesis” (Maher (...) 1988).It is primarily philosophers who are interested in this question, and they have treated it mostly as a normative or logical problem. Can the writings of historians of science tell us how scientists have treated novel predictions in the past? Until recently historians have rarely addressed this point. (shrink)
