The present study aims to examine the relationship between the cortical midline structures (CMS), which have been regarded to be associated with selfhood, and moral decision making processes at the neural level. Traditional moral psychological studies have suggested the role of moral self as the moderator of moral cognition, so activity of moral self would present at the neural level. The present study examined the interaction between the CMS and other moral-related regions by conducting psycho-physiological interaction analysis of functional images (...) acquired while 16 subjects were solving moral dilemmas. Furthermore, we performed Granger causality analysis to demonstrate the direction of influences between activities in the regions in moral decision-making. We first demonstrate there are significant positive interactions between two central CMS seed regions—i.e., the medial prefrontal cortex (MPFC) and posterior cingulate cortex (PCC)—and brain regions associated with moral functioning including the cerebellum, brainstem, midbrain, dorsolateral prefrontal cortex, orbitofrontal cortex and anterior insula (AI); on the other hand, the posterior insula (PI) showed significant negative interaction with the seed regions. Second, several significant Granger causality was found from CMS to insula regions particularly under the moral-personal condition. Furthermore, significant dominant influence from the AI to PI was reported. Moral psychological implications of these findings are discussed. The present study demonstrated the significant interaction and influence between the CMS and morality-related regions while subject were solving moral dilemmas. Given that, activity in the CMS is significantly involved in human moral functioning. (shrink)

This study compares the neural substrate of moral decision making processes between Korean and American participants. By comparison with Americans, Korean participants showed increased activity in the right putamen associated with socio-intuitive processes and right superior frontal gyrus associated with cognitive control processes under a moral-personal condition, and in the right postcentral sulcus associated with mental calculation in familiar contexts under a moral-impersonal condition. On the other hand, American participants showed a significantly higher degree of activity in the bilateral anterior (...) cingulate cortex (ACC) associated with conflict resolution under the moral-personal condition, and in the right medial frontal gyrus (MFG) associated with simple cognitive branching in non-familiar contexts under the moral-impersonal condition when a more lenient threshold was applied, than Korean participants. These findings support the ideas of the interactions between the cultural background, education, and brain development, proposed in the field of cultural psychology and educational psychology. The study introduces educational implications relevant to moral psychologists and educators. (shrink)

A review of Personhood, Ethics, and Animal Cognition: Situating Animals in Hare’s Two-Level Utilitarianism, by Gary E. Varner. New York, NY: Oxford University Press, 2012. Pp. xv + 336.

This chapter concerns the role accorded to animals in the theories of the English-speaking philosophers who created the field of environmental ethics in the latter half of the twentieth century. The value of animals differs widely depending upon whether one adopts some version of Holism (value resides in ecosystems) or some version of Animal Individualism (value resides in human and nonhuman animals). I examine this debate and, along the way, highlight better and worse ways to conduct ethical arguments. I explain (...) that two kinds of appeals (which I call intuition and reductio) are questionable foundations for environmental ethics and that representatives of both schools occasionally appeal unhelpfully to intuition or caricature the commitments of the other side. I review two stronger arguments for Ecoholism (inference and eco-organisms) and show that they have performed a useful function in environmental ethics. Ultimately, however, both arguments fail because their proponents are unable to answer four critical objections: weakness of will, no eco-organisms, no teleology, and is/ought. I then show that Animal Individualism operates on more secure footing when it comes to philosophical and scientific assumptions. I also propose that Animal Individualism is more likely to prove effective in establishing progressive environmental policies insofar as it builds on existing legal concepts, especially the concept of moral rights, and political institutions, such as democratic states. I note that wild animals are not inherently more valuable than domestic animals and, finally, offer a brief outline of an animal rights environmental ethic. (shrink)

This paper studies in detail about the early years of José Gaos (1900- 1969) and his education in philosophy and literature. Therefore, we know that their studies (academic or not) were not purely “philosophical” in 1915. Literature and philosophy played in Gaos an equally important role. The first real encounter with philosophy happens before he comes to Valencia in 1915; but in this year Gaos also receives a strong education, in aesthetic and literary, through press and philosophical journals, and especially (...) within the group formed with Max Aub, José Medina Echeverría and his brother Carlos Gaos.

Sweden features near the top of most gender-equality rankings. The World Economic Forum rates it as having one of the narrowest gender gaps in the world. But Sweden is not only a good place to be a woman: it also appears to be an idyll for new dads. Close to 90% of Swedish fathers take paternity leave. In 2013, some 340,000 dads took a total of 12 million days’ leave, equivalent to about seven weeks each. Women take even more leave (...) days to spend time with their children, but the gap is shrinking. Why do Swedish dads take so much time off work to raise their children? (shrink)

En este texto se analiza cómo el filósofo español exiliado en México, José Gaos (1900- 1969), considera que la filosofía hispanoamericana, e incluso las propias tierras americanas, son lugares de una “utopía – aunque no ucronía-, debido a que tanto las tradiciones trascendente-religiosas como inmanente-filosóficas europeas han convertido a América, y como resultado final de una determinada filosofía de la historia, en lugar ideal del futuro del pensamiento filosófico –y, en última instancia, del hombre contemporáneo.

A tongue-in-cheek send-up of certain aspects of existentialism written by a well-known logician and philosopher who had a serious affair with existentialism in his youth.

This article presents a critical reevaluation of the thesis—closely associated with H. L. A. Hart, and central to the views of most recent legal philosophers—that the idea of state coercion is not logically essential to the definition of law. The author argues that even laws governing contracts must ultimately be understood as “commands of the sovereign, backed by force.” This follows in part from recognition that the “sovereign,” defined rigorously, at the highest level of abstraction, is that person or entity (...) identified by reference to game theory and the philosophical idea of “convention” as the source of signals with which the subject population has become effectively locked, as a group, into conformity.

The expanding moral circle lends coherence to the usual hodge-podge of canonical RCR topics. As it is in a person’s own interest to report falsification, understand fabrication, avoid plagiarism, beware of intuition, and justify one’s decisions, it is useful to begin RCR discussions with the principle that we ought to do what is in our own long-term best interests. As it is in the interest of a person’s research group to articulate their reasons for their conclusions, to write cooperatively, review (...) manuscripts professionally, and report statistics transparently, one can introduce the principle that we ought to keep our promises and contracts. As it is a basic matter of rights to respect human subjects, mentor inclusively, recognize intellectual property, and reveal both conflicts of interests and collaborations with private industry, an RCR instructor can introduce the idea that we ought to respect each individual’s moral rights. Finally, as many animals can feel pain, are subjects of their own lives, and have interests of their own, we must take seriously our role in their welfare as research subjects. In this last step, we expand the circle fully, considering animal experimentation, duties to future generations and the natural environment, and the larger social responsibilities of researchers while adopting a utilitarian principle: We ought to do what will maximize aggregate happiness.

This chapter examines the mechanistic psychology of Descartes in the _Passions_, while also drawing on the _Treatise on Man_. It develops the idea of a Cartesian “psychology” that relies on purely bodily mechanisms by showing that he explained some behaviorally appropriate responses through bodily mechanisms alone and that he envisioned the tailoring of such responses to environmental circumstances through a purely corporeal “memory.” An animal’s adjustment of behavior as caused by recurring patterns of sensory stimulation falls under the notion of (...) “learning,” behavioristically conceived. Indeed, Descartes’s animal-machine hypothesis may well be a distant ancestor to Watsonian behaviorism, via T. H. Huxley (1884). The final two sections of the chapter take stock of what psychological capacities Descartes ascribed to mind, body, or both, and consider those capacities that we might now plausibly construe as being explicable by nonmentalistic mechanisms as opposed to those that at present remain unreducedly mentalistic. -/- This chapter derives from a lecture delivered at the University of King's College (Halifax, Nova Scotia) as part of a year-long series on Descartes and the Modern. The lecture series was co-sponsored by the programs in History of Science and Early Modern and Contemporary Studies. (shrink)

We describe a simple, flexible exercise that can be implemented in the philosophy of science classroom: students are asked to determine the contents of a closed container without opening it. This exercise has revealed itself as a useful platform from which to examine a wide range of issues in the philosophy of science and may, we suggest, even help us think about improving the public understanding of science.

THERE IS WIDESPREAD AGREEMENT among historians that the writings of Robert Boyle (1697-1691) constitute a valuable archive for understanding the concerns of seventeenth-century British natural philosophers. His writings have often been seen as representing, in one fashion or another, all of the leading intellectual currents of his day. ~ There is somewhat less consensus, however, on the proper historiographic method for interpreting these writings, as well as on the specific details of the beliefs expressed in them. Studies seeking to explicate (...) Boyle's thought have been, roughly speaking, of two general sorts. On the one hand there are those studies of a broadly "intellectualist" orientation which situate his natural philosophy within the intellectual context provided by metaphysics, religion, and early modern science. In this connection his corpuscularianism has been shown to be motivated by specific epistemological, theological, as well as empirical concerns. One of the central aims of such studies has been to show that apparently discordant elements in his scientific thought are rendered coherent by referring them to such "non-scientific" commitments. Among studies of this sort might be mentioned the works of John Hedley Brooke, E. A. Burtt, Gary B. Deason, J. E. McGuire, R. Hooykaas, Robert H. Kargon, Eugene M. Klaaren, P. M. Rattansi, and Richard S. Westfall. (shrink)

The National Library of Finland and the Von Wright and Wittgenstein Archives at the University of Helsinki keep the collected correspondence of Georg Henrik von Wright, Wittgenstein’s friend and successor at Cambridge and one of the three literary executors of Wittgenstein’s Nachlass. Among von Wright’s correspondence partners, Elizabeth Anscombe and Rush Rhees are of special interest to Wittgenstein scholars as the two other trustees of the Wittgenstein papers. Thus, von Wright’s collections held in Finland promise to shed light on the (...) context of decades of editorial work that made Wittgenstein’s later philosophy available to all interested readers. In this text, we present the letters which von Wright received from Anscombe and Rhees during the first nine months after Wittgenstein’s death. This correspondence provides a vivid picture of the literary executors as persons and of their developing relationships. The presented letters are beautiful examples of what the correspondence as a whole has to offer; it depicts – besides facts of editing – the story of three philosophers, whose conversing voices unfold the human aspects of inheriting Wittgenstein’s Nachlass. Their story does not only deal with editing the papers of an eminent philosopher, but with the attempt to do justice to the man they knew, to his philosophy and to his wishes for publication.

With his 1998 book, In Nature’s Interests? Gary Varner proved to be one of our most original and trenchant of environmental ethicists. Here, in the first of a promised two volume set, he makes his mark on another field, animal ethics, leaving an even deeper imprint. Thoroughly grounded in the relevant philosophical and scientific literatures, Varner is as precise in analysis as he is wide-ranging in scope. His writing is clear and rigorous, and he explains philosophical nuances with extraordinary (...) economy of expression. Never one to add an unnecessary clause to a sentence, Varner nonetheless constructs a formidable edifice while always dealing fairly with the authors he criticizes. His explication of the properties and moral status of what he calls near-persons is a crucial addition to the discussion of personhood initiated by Parfit in Reasons and Persons and subsequently applied to animals by McMahan in The Ethics of Killing. The comparison to McMahan is intentional for, to my mind, Varner vies with him as the most important animal ethicist since Singer and Regan. (shrink)

The law presents itself as a body of meaning, open to discovery, interpretation, application, criticism, development and change. But what sort of meaning does the law possess? Legal theory provides three sorts of answers. The first portrays the law as a mode of communication through which law-makers convey certain standards or norms to the larger community. The law's meaning is that imparted by its authors. On this view, law is a vehicle, conveying a message from a speaker to an intended (...) audience. The second theory portrays the law as a mode of interpretation, whereby judges, officials, and ordinary citizens make decisions about how the law applies in various practical contexts. The law's meaning is that furnished by its interpreters. According to this theory, law is a receptacle into which decision-makers pour meaning. The third viewpoint argues that these theories, while not altogether wrong, are incomplete because they downplay or ignore the autonomous meaning that the law itself possesses. This theory suggests that the law is basically a mode of participation, whereby legislators, judges, officials, and ordinary people attune themselves to an autonomous field of legal meaning. The law's meaning is grounded in a body of social practice which is independent of both the law's authors and its interpreters and which is infused with basic values and principles that transcend the practice. On this view, law is the emblem of meaning that lies beyond it. -/- Elements of all three theories are present in H.L.A. Hart's influential work, The Concept of Law, which attempts to fuse them into a single, all-encompassing theory. Nevertheless, as we will argue here, the attempt is not successful. Any true reconciliation of the communication and interpretation theories can only take place within the framework of a fully developed participation theory. In the early stages of his work, Hart lays the foundation for such a theory. However, his failure to elaborate it in a thoroughgoing way renders the work incomplete and ultimately unbalanced. As we will see, there is something to be learned from this failure. (shrink)

The paper is an examination and critique of the philosophy of science fiction horror of seminal American horror, science fiction and fantasy writer H.P. Lovecraft (1890-1937). Lovecraft never directly offers a philosophy of science fiction horror. However, at different points in his essays and letters, he addresses genres he labels “interplanetary fiction”, “horror”, “supernatural horror”, and “weird fiction”, the last being a broad heading covering both supernatural fiction and science fiction. Taken together, a philosophy of science fiction horror emerges. Central (...) to this philosophy is the juxtaposition of the mysterious, unnatural and alien against a realistic background, in order to produce the emotion that Lovecraft calls “cosmic fear”. This background must not only be scientifically accurate, but must accurately portray human psychology, particularly when humans are faced with the weird and alien. It will be argued that Lovecraft’s prescriptions are overly restrictive and would rule out many legitimate works of science fiction horror art. However, he provides useful insights into the genre.

In this essay I argue that the central problem of Aristotle’s Metaphysics H (VIII) 6 is the unity of forms and that he solves this problem in just the way he solves the problem of the unity of composites – by hylomorphism. I also discuss the matter– form relationship in H 6, arguing that they have a correlative nature as the matter of the form and the form of the matter.

Although Foucault’s 1979 lectures on The Birth of Biopolitics promised to treat the theme of biopolitics, the course deals at length with neoliberalism while mentioning biopolitics hardly at all. Some scholars account for this elision by claiming that Foucault sympathized with neoliberalism; I argue on the contrary that Foucault develops a penetrating critique of the neoliberal claim to preserve individual liberty. Following Foucault, I show that the Chicago economist Gary Becker exemplifies what Foucault describes elsewhere as biopolitics: a form (...) of power applied to the behavior of a population through the normalizing use of statistics. Although Becker’s preference for indirect intervention might seem to preserve the independence of individuals, under biopolitics individual liberty is itself the means by which populations are governed indirectly. In my view, by describing the history and ambivalence of neoliberal biopolitics, Foucault fosters a critical vigilance that is the precondition for creative political resistance. (shrink)

During the period 1870-1914 the existing discipline of psychology was transformed. British thinkers including Spencer, Lewes, and Romanes allied psychology with biology and viewed mind as a function of the organism for adapting to the environment. British and German thinkers called attention to social and cultural factors in the development of individual human minds. In Germany and the United States a tradition of psychology as a laboratory science soon developed, which was called a 'new psychology' by contrast with the old, (...) metaphysical psychology. Methodological discussion intensified. New syntheses were framed. Chairs were established and Departments founded. Although the trend toward institutional autonomy was less rapid in Britain and France, significant work was done by the likes of Galton and Binet. Even in Germany and America the purposeful transformation of the old psychology into a new, experimental science was by no means complete in 1914. And while the increase in experimentation changed the body of psychological writing, there was considerable continuity in theoretical content and non-experimental methodology between the old and new psychologies. This chapter follows the emergence of the new psychology out of the old in the national traditions of Britain, Germany, and the United States, with some reference to French, Belgian, Austrian, and Italian thinkers. While the division into national traditions is useful, the psychological literature of the second half of the nineteenth century was generally a European literature, with numerous references across national and linguistic boundaries, and it became a North Atlantic literature as psychology developed in the United States and Canada. The order of treatment, Britain, Germany, and the US, follows the center of gravity of psychological activity. The final section considers some methodological and philosophical issues from these literatures. (shrink)

It seems intuitively obvious that metameric matching of color samples entails a loss of information, for spectrophotometrically diverse materials appear the same. This intuition implicitly relies on a conception of the function of color vision and on a related conception of how color samples should be individuated. It assumes that the function of color vision is to distinguish among spectral energy distributions, and that color samples should be individuated by their physical properties. I challenge these assumptions by articulating a different (...) conception of the function of color vision, according to which color vision serves to partition object surfaces into discrimination classes.

Utilitarianism has a fairly bad reputation in military ethics, mainly because it is thought to make military expedience override all other concerns. The atomic bombing of Hiroshima and Nagasaki is a famous instance of such a skewed utilitarian calculation that “the rules of war and the rights they are designed to protect” should have stopped (Walzer 1992: 263-8). Most of its critics seem to think that utilitarianism is not bad per se, but prone to be misapplied in a self-serving way. (...) That idea, William H. Shaw argues in his careful and mostly convincing defense of utilitarian thinking about the moral issues that war occasions, is misguided, as are most of the other common objections to utilitarian thinking about the moral issues war raises.

Why is humour so hard to understand? Rather like attempts to explain how music can move us, attempts to explain why things are funny seem doomed from the outset. Discussions of humour typically distinguish three kinds of theory: the incongruity theory (we are amused by the incongruous), the relief theory (humour is an expression of relief in difficult situations) and the superiority theory (we laugh to express our sense of superiority over others). In the face of genuine humour, theories like (...) these can seem pedestrian and unconvincing. F.H. Buckley’s book is, unfortunately, no exception to this rule. Coming from the superiority camp, the book defends two theses about humour. (Professor Buckley’s own word is ‘laughter’, but it is clear that he is really interested in why we laugh rather than laughter itself.) The first is what he calls the ‘Positive’ thesis: that all humour is the expression of a sense of superiority over someone else, whom he names ‘the butt’. The second he calls the ‘Normative’ thesis: that those who laugh really are superior to the butt. (shrink)

This paper examines Helmholtz's attempt to use empirical psychology to refute certain of Kant's epistemological positions. Particularly, Helmholtz believed that his work in the psychology of visual perception showed Kant's doctrine of the a priori character of spatial intuition to be in error. Some of Helmholtz's arguments are effective, but this effectiveness derives from his arguments to show the possibility of obtaining evidence that the structure of physical space is non-Euclidean, and these arguments do not depend on his theory of (...) vision. Helmholtz's general attempt to provide an empirical account of the "inferences" of perception is regarded as a failure. (shrink)

In this retrospective for Ethics, I discuss H.M. Oliver’s “Established Expectations and American Economic Policies.” This article, by a then-modestly-famous economist, has been ignored (no citations) since its 1940 publication. Yet it bears directly on a normative problem at the intersection of ethics and economics that challenges today’s policymakers but has received comparatively little philosophical attention: how should we balance potentially desirable institutional change against the disruption of established expectations? -/- Oliver details how the principle of fulfilling established expectations cuts (...) across political lines. Conservatives, he observes, criticized inflation for disrupting expectations, and demanded the protection of established corporations. New Deal progressives achieved “the safeguarding of the economic positions of certain important sections of the American people” (104) via statutes designed to protect income and homeownership status. And labor leaders lobbied for the preservation of occupational status. Oliver criticizes these demands on two grounds. First, they are noncompossible: they can’t simultaneously be fulfilled. Second, they are economically inefficient. He concludes that “in a modern dynamic economy, the preservation of status is not and cannot be a feasible criterion of economic justice” (107). -/- I argue that Oliver accurately recognizes both the wide endorsement and the moral ill-foundedness of fulfilling expectations. However, I criticize Oliver’s belief in the noncompossibility of expectations. The established expectations of the wealthy, middle-class homeowners and retirees, and current workers can all be maintained, but at the price of constricting the opportunities of new graduates, immigrants, and the poor—all groups yet to develop settled expectations. This insight renders the protection of expectations not merely inefficient but also unjust. (shrink)

The Twin Earth thought experiment invites us to consider a liquid that has all of the superficial properties associated with water (clear, potable, etc.) but has entirely different deeper causal properties (composed of “XYZ” rather than of H2O). Although this thought experiment was originally introduced to illuminate questions in the theory of reference, it has also played a crucial role in empirically informed debates within the philosophy of psychology about people’s ordinary natural kind concepts. Those debates have sought to accommodate (...) an apparent fact about ordinary people’s judgments: Intuitively, the Twin Earth liquid is not water. We present results from four experiments showing that people do not, in fact, have this intuition. Instead, people tend to have the intuition that there is a sense in which the liquid is not water but also a sense in which it is water. We explore the implications of this finding for debates about theories of natural kind concepts, arguing that it supports views positing two distinct criteria for membership in natural kind categories – one based on deeper causal properties, the other based on superficial, observable properties.

An active suspension system is taken into consideration better than the passive suspension system. In this paper, an active suspension system of a linear quarter vehicle is designed, that's issue to exclusive disturbances on the road. Since the parametric uncertainty within the spring, the shock absorber and the actuator has been taken into consideration, robust control is used. H∞ and µ-Synthesis controllers of are used (...) to improve using consolation and road dealing with potential of the vehicle, in addition to confirm the sturdy stability and overall performance of the system. In the H∞ design, we designed a driving force for passenger consolation and to preserve the deflection of the suspension small and to reduce the disturbance of the road to the deflection of the suspension. For the µ synthesis system, we designed a controller with hydraulic actuator and uncertainty model. We designed a MATLAB / SIMULINK model for the active suspension system with the H∞ and µ-synthesis controllers we tested the use of 4 road disturbance inputs (bump, random, sinusoidal pavement and slope) for deflection of the suspension, body acceleration and body travel for passive, active suspension with controller and active suspension without controller. Finally, we evaluate the H∞ and µ-synthesis controllers with a Simulink model for suspension deflection, body acceleration and body travel simulation, and the result suggests that both designs offer correct overall performance, however the H∞ controller has superior overall performance as compared to the µ-synthesis controller.
