This text explores how human beings construe experience: experience as a resource, as a potential for understanding, representing and acting on reality.

In a recent paper, Kaplan (Synthese 183:339–373, 2011) takes up the task of extending Craver’s (Explaining the brain, 2007) mechanistic account of explanation in neuroscience to the new territory of computational neuroscience. He presents the model to mechanism mapping (3M) criterion as a condition for a model’s explanatory adequacy. This mechanistic approach is intended to replace earlier accounts which posited a level of computational analysis conceived as distinct and autonomous from underlying mechanistic details. In this paper I discuss work in (...) computational neuroscience that creates difficulties for the mechanist project. Carandini and Heeger (Nat Rev Neurosci 13:51–62, 2012) propose that many neural response properties can be understood in terms of canonical neural computations. These are “standard computational modules that apply the same fundamental operations in a variety of contexts.” Importantly, these computations can have numerous biophysical realisations, and so straightforward examination of the mechanisms underlying these computations carries little explanatory weight. Through a comparison between this modelling approach and minimal models in other branches of science, I argue that computational neuroscience frequently employs a distinct explanatory style, namely, efficient coding explanation. Such explanations cannot be assimilated into the mechanistic framework but do bear interesting similarities with evolutionary and optimality explanations elsewhere in biology. (shrink)

This article examines three candidate cases of non-causal explanation in computational neuroscience. I argue that there are instances of efficient coding explanation that are strongly analogous to examples of non-causal explanation in physics and biology, as presented by Batterman, Woodward, and Lange. By integrating Lange’s and Woodward’s accounts, I offer a new way to elucidate the distinction between causal and non-causal explanation, and to address concerns about the explanatory sufficiency of non-mechanistic models in neuroscience. I also use this framework to (...) shed light on the dispute over the interpretation of dynamical models of the brain. _1_ Introduction _1.1_ Efficient coding explanation in computational neuroscience _1.2_ Defining non-causal explanation _2_ Case I: Hybrid Computation _3_ Case II: The Gabor Model Revisited _4_ Case III: A Dynamical Model of Prefrontal Cortex _4.1_ A new explanation of context-dependent computation _4.2_ Causal or non-causal? _5_ Causal and Non-causal: Does the Difference Matter?

This paper is devoted to the study of some subvarieties of the variety Qof Q-Heyting algebras, that is, Heyting algebras with a quantifier. In particular, a deeper investigation is carried out in the variety Q 3 of three-valued Q-Heyting algebras to show that the structure of the lattice of subvarieties of Qis far more complicated that the lattice of subvarieties of Heyting algebras. We determine the simple and subdirectly irreducible algebras in Q 3 and we construct the lattice of subvarieties (...) (Q 3 ) of the variety Q 3. (shrink)

Traditional Chinese commentators rightly see that understanding Zhuangzi's way with words is the presupposition for understanding Zhuangzi at all. They are not sure, however, if Zhuangzi's words are super-effective or pure nonsense. I consider Zhuangzi's experience with language, and then turn to Heidegger's word of being to see if it may throw light on Zhuangzi's way of saying. I argue that a conversation between Heidegger and Zhuangzi on language is possible, but only by expanding Heidegger's notion of Gestell and through (...) a destruction of the dominant Confucian discourse that obscures Zhuangzi's way of saying.

Feminist Geneaologies, Colonial Legacies, Democratic Futures provides a feminist anaylsis of the questions of sexual and gender politics, economic and cultural marginality, and anti-racist and anti-colonial practices both in the "West" and in the "Third World." This collection, edited by Jacqui Alexander and Chandra Talpade Mohanty, charts the underlying theoretical perspectives and organization practices of the different varieties of feminism that take on questions of colonialism, imperialism, and the repressive rule of colonial, post-colonial and advanced capitalist nation-states. It provides a (...) comparative, relational, historically grounded conception of feminist praxis that differs markedly from the liberal pluralist, multicultural understanding that sheapes some of the dominant version of Euro-American feminism. As a whole, the collection poses a unique challenge to the naturalization of gender based in the experiences, histories and practices of Euro-American women. (shrink)

Recent work in philosophy of science has shown how the challenges posed by extremely complex systems require that scientists employ a range of modelling strategies, leading to partial perspectives that make apparently conflicting claims about the target (Mitchell 2009b, Longino 2013). The brain is of course extremely complex, and the same arguments apply here. In this paper I present a variety of perspectivism called _haptic realism_. This account foregrounds the process by which the instrumental goals of neuroscience shape the way (...) that objects of investigation are probed experimentally and conceptualised through modelling. Because such models do not aim to represent their targets exactly as they are, but in ways that are most useful for the investigators, the models should not be interpreted as literal descriptions of neural systems. Scientific realism traditionally involves a semantic commitment to interpreting theories and models as literal descriptions of human-independent nature. Haptic realism makes a significant departure from this tradition. Haptic realism also calls us to reassess the ontological commitments and knowledge claims of neuroscientific models and theories.

What is colour vision for? In the popular imagination colour vision is for “seeing the colours” — adding hue to the achromatic world of shape, depth and motion. On this view colour vision plays little more than an ornamental role, lending glamour to an otherwise monochrome world. This idea has guided much theorising about colour within vision science and philosophy. However, we argue that a broader approach is needed. Recent research in the psychology of colour demonstrates that colour vision is (...) integral to a variety of visual processes, helping us to perform many types of visual tasks. We discuss some of this research and consider its implications for philosophical theories of colour. (shrink)

Numerous studies indicate that racial minorities are both more likely to be executed for murder and that those who murder them are less likely to be executed than if they murder whites. Death penalty opponents have long attempted to use these studies to argue for a moratorium on capital punishment. Whatever the merits of such arguments, they overlook the fact that such discrimination alters the costs of murder; racial discrimination imposes higher costs on minorities for murdering through tougher sentences, and (...) it imposes lower costs on whites for murdering minorities by dispensing weaker sentences. These cost differentials constitute an injustice not simply to actual minority defendants in capital cases, nor simply to the actual minority victims of murder, but to all members of minority communities. I here offer two arguments for a moratorium on capital punishment: The first draws upon evidence of racial discrimination against minority defendants in capital cases, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy equal status under the law. The second draws upon the evidence regarding racial discrimination in relation to the race of victims, and claims that such discrimination modifies the costs of murder in such a way that minority individuals do not enjoy the equal protection of the law. Thus, by not assigning equal costs to murder, the American criminal justice system fails to provide racial minorities the equality under the law and discounts the value of their lives and liberties. A moratorium is the least unjust response to such a social injustice. I also reply to the criticism that a moratorium prevents us from executing deserving murderers. (shrink)

In this paper, I offer a view beyond that which would narrowly reduce the role of parents in medical decision making to acting as custodians of the best interests of children and toward an account of family authority and family autonomy. As a fundamental social unit, the good of the family is usually appreciated, at least in part, in terms of its ability successfully to instantiate its core moral and cultural understandings as well as to pass on such commitments to (...) future generations. The putative rights of children to expression, information, freedom of thought, conscience, religion, and to freedom of association with others are, in this essay, assessed from the perspective of those conditions necessary for the family to function as a moral community. In so doing, I respond to the move to liberate children from parental authority and to effect the transformation of the family as implied by the United Nations’ "Convention on the Rights of the Child" and the pediatric bioethics it supports.

In Roper v. Simmons (2005) the United States Supreme Court announced a paradigm shift in jurisprudence. Drawing specifically on mounting scientific evidence that adolescents are qualitatively different from adults in their decision-making capacities, the Supreme Court recognized that adolescents are not adults in all but age. The Court concluded that the overwhelming weight of the psychological and neurophysiological data regarding brain maturation supports the conclusion that adolescents are qualitatively different types of agents than adult persons. The Supreme Court further solidified (...) its position regarding adolescents as less than fully mature and responsible decisionmakers in Graham v. Florida (2010) and Miller v. Alabama (2012). In each case, the Court concluded that the scientific evidence does not support the conclusion that children under 18 years of age possess adult capacities for personal agency, rationality, and mature choice. This study explores the implications of the Supreme Court decisions in Roper v. Simmons, Graham v. Florida, and Miller v. Alabama for the “mature minor” standard for medical decision making. It argues that the Supreme Court’s holdings in Roper, Graham, and Miller require no less than a radical reassessment of how healthcare institutions, courts of law, and public policy are obliged to regard minors as medical decisionmakers. The “mature minor” standard for medical decision making must be abandoned. (shrink)

In this article I examine the perceptual metaphor at the heart of perspectivism, discussing three elements: partiality, interestedness, and interaction. I argue that perspectivists should drop the visual metaphor in favor of a haptic one. Because the sense of touch requires contact and purposeful exploration on the part of the perceiver, it is obvious that with touch one apprehends an extradermal reality in virtue of and not in spite of its interactive and interested nature. By analogy, perspectivists should investigate the (...) thesis that scientific representations inform us about the natural world in virtue of their interactive and interested qualities. (shrink)

Objections to the computational theory of cognition, inspired by twentieth century phenomenology, have tended to fixate on the embodiment and embeddedness of intelligence. In this paper I reconstruct a line of argument that focusses primarily on the abstract nature of scientific models, of which computational models of the brain are one sort. I observe that the critique of scientific abstraction was rather commonplace in the philosophy of the 1920s and 30s and that attention to it aids the reading of The (...) Organism ([1934] 1939) by the neurologist Kurt Goldstein. With this background in place, we see that some brief but spirited criticisms of cybernetics by two later thinkers much influenced by Goldstein, Georges Canguilhem (1963) and Maurice Merleau-Ponty (1961), show continuity with the earlier discussions of abstraction in science.

In Kidney for Sale by Owner: Human Organs, Transplantation, and the Market, I argued that the market is the most efficient and effective—and morally justified—means of procuring and allocating human organs for transplantation. This special issue of The Journal of Medicine and Philosophy publishes several articles critical of this position and of my arguments mustered in its support. In this essay, I explore the core criticisms these authors raise against my conclusions. I argue that clinging to comfortable, but unfounded, notions (...) that human body parts are not commodities, that the physician-patient relationship transcends commercial practices, and that medicine rises above market-place morality (where “market-place morality” is presented rhetorically as a criticism) leads to a real failure adequately to appreciate the complex reality of modern medicine. Denying the illicit moral intuitions that commodification of body parts is immoral or that it necessarily violates human dignity would benefit donors and recipients alike, while also reinforcing virtuous transplantation practice and policy. Honestly acknowledging the medical marketplace would shed light on what is often a hazy and shrouded policy setting. At stake is not solely the efficiency of procuring human organs for transplantation but also the recognition of the moral authority of persons over themselves. (shrink)

Mental disorders in university students are very frequent, therefore higher education institutions have established in-campus mental healthcare centres. These clinics have particular characteristics that differ from other mental health centres, as they report to and represent an educational institution, while at the same time looking after the interests and well-being of patients requesting assistance, thus generating unique bioethical conflicts. Ethics Committees are useful tools to offer support to mental health professionals in making ethical decisions. In order to respond to these (...) issues, it was decided that an Ethics Committee would be created in the mental health clinic of a private university in Mexico City. This article describes the implementation process for this Committee, its duties and scope, as well as the case work and review methodology. A list of the most frequent ethical conflicts is attached, jointly with the ethical analysis of the cases treated throughout the year and a half or work by the Committee. (shrink)

This article examines the mutual influence between Ernst Cassirer and his cousin, the neurologist Kurt Goldstein. For both Cassirer and Goldstein, views on the nature of human cognition were fundamental to their understanding of scientific knowledge, and these were informed by both philosophical theorizing and empirical research on pathologies of the nervous system. Following Cassirer, and in agreement with the physicalism of the Vienna Circle, Goldstein held that the physical sciences had progressed by arriving at abstract, mathematical representations to take (...) the place of qualitative characterizations of observable reality. In tension with physicalism, Goldstein was not sanguine about the fruitfulness of the abstractive approach in biology. He proposed that biology must adhere to its own sui generis methods of observation and experimentation in order to obtain knowledge of the “natures” of living organisms. I argue that there is a parallel with Cassirer’s assertion of the differences between physical and cultural sciences, underwritten by the deployment of varying symbolic functions. I also propose that the neurological writings of Goldstein are an important backdrop to Cassirer’s positive evaluation of abstract thought, in contrast to the pessimism regarding a worldview dominated by scientific abstractions expressed by philosophers such as Bergson, Whitehead, and Husserl.

I argue that Metz's undertaking, in seeking a ‘comprehensive basic norm' to underpin African ethics, is similar to Hans Kelsen's postulation of the Grundnorm in his Pure Theory of Law. But African ethics does not need to be underpinned by an approach such as Kelsen's. In my view, Metz's preference for seeking to develop a Grundnorm rests upon a failure to attend carefully to the distinctness of African ethical thinking from Western ethical thinking. This failure is manifest in a spurious (...) distinction between ‘moral anthropology' / ‘cultural studies' and ‘normative theory'. It is also manifest in Metz's failure to attend carefully to the work of Wiredu and Bujo, both of whom present systematic, critical analyses of African ethical thinking while implicitly rejecting the quest for a Grund norm as being unAfrican.

To seek fundamental truths, analytic metaphysicians generally start with observed phenomena. From here they typically move outwards, using discursive thought to posit scientifically informed theories about the ultimate reality behind appearances. Mystics, too, seek to uncover the reality behind appearances. However, their meditative methods typically start with experience and go inwards to a fundamental reality sometimes described as a pure conscious unity. Analytic metaphysicians may be tempted to dismiss the mystical approach as unworthy of investigation. In this paper I will (...) outline and address four challenges that sceptics are likely to advance, arguing that none is persuasive. I shall also attempt to clarify the role and scope of meditation in establishing the viability of mystical data in the construction of any potential metaphysic about fundamental reality. (shrink)

Parental decision making is necessary for contracting medical interventions that require personal risk–benefit evaluation, and for overseeing matters of education. In the nineteenth century, exemptions from obligatory vaccination were granted for religious and conscientious reasons. Then and today, religion and moral values play marginal roles in vaccine hesitancy and denialism. Rather, the key values invoked by vaccine hesitants and denialists are liberty and pluralism. Neither is compatible with limiting adolescents’ choice. Because vaccination does not require assessment of personal medical risks, (...) because it does not need to occur within the sphere of the doctor–patient relationship, and because the risk involved is within the range of their daily activities, adolescents have the right to free access to vaccination without legal requirement of parental involvement. Drawing on the development of Common Law, and on the development of respect for personal conscience in the history of ideas, this paper does not promote an argument that grants public health an overriding moral power. Rather, this paper rejects the presumption that vaccination of adolescents might involve a conflict between parental authority and public health. Free access to vaccination is compatible with the law and ethics of adolescents’ evolving autonomy in relation to healthcare. (shrink)

In this article, I discuss the concept of robustness in neuroscience. Various mechanisms for making systems robust have been discussed across biology and neuroscience. Many of these notions originate from engineering. I argue that concepts borrowed from engineering aid neuroscientists in operationalizing robustness, formulating hypotheses about mechanisms for robustness, and quantifying robustness. Furthermore, I argue that the significant disanalogies between brains and engineered artifacts raise important questions about the applicability of the engineering framework. I argue that the use of such (...) concepts should be understood as a kind of simplifying idealization. (shrink)

The victory of realism over idealism at the start of the twentieth century, and of scientific realism over logical empiricism and pragmatism in the mid twentieth century, is a striking phenomenon that calls for historical explanation. In this paper I propose an externalist account, looking at the social and political reasons why realism became attractive, rather than considering the internal factors–the merits of the arguments in favour of realism. I look at the agenda of Roy Wood Sellars’ critical realism which (...) was not narrowly theoretical, but very much related to his concerns for the development of American society post WW1, as expressed in The Next Step in Democracy (1916b) and The Next Step in Religion (1918). I discuss the significance of technocracy in America – not only the increasing influence of scientists and engineers in government, but also the diffusion of the view that social issues are best addressed by scientific, technical means. Counter-cultural critics of technocracy, such as Roszak (1969) claimed that a “scientific world-view” provided an “ideology” for this system of governance. We will see that RW Sellars was explicitly involved in the task of building a scientific world-view, but with political goals that were probably not realised by the post-war establishment. (shrink)

The United Nations Educational, Scientific, and Cultural Organization's (UNESCO) Universal Declaration on Bioethics and Human Rights announces a significant array of welfare entitlements—to personal health and health care, medicine, nutrition, water, improved living conditions, environmental protection, and so forth—as well as corresponding governmental duties to provide for such public health measures, though the simple expedient of announcing that such entitlements are “basic human rights.” The Universal Declaration provides no argument for the legitimacy of the sweeping governmental authority, taxation, and regulation (...) to create and impose such “rights.” As this paper explores that some action promotes a purported good, such as “health,” does not thereby make the action morally permissible. Just as there are moral limits on legitimate personal actions, there are also moral limits on legitimate governmental actions to promote purported goods, including health. A core question of any governmental regulation, therefore, is whether it is a legitimate application of moral political authority or an unauthorized act of state coercion. Pace UNESCO's wide-ranging assertions, this paper argues that promoting health only falls within the legitimate authority of governments in very narrowly defined circumstances. As the paper critically explores, at stake are foundational moral and political questions concerning the limits of governmental authority to intervene in the consensual interaction of persons. Imposing such duties on others, including citizens of a state through regulatory activity and taxation, must be justified, nonarbitrary, and demonstrably within the limits of moral political authority. UNESCO's assertions do not meet this burden of proof. (shrink)

The total and the sharp character of orthodox quantum logic has been put in question in different contexts. This paper presents the basic ideas for a unified approach to partial and unsharp forms of quantum logic. We prove a completeness theorem for some partial logics based on orthoalgebras and orthomodular posets. We introduce the notion of unsharp orthoalgebra and of generalized MV algebra. The class of all effects of any Hilbert space gives rise to particular examples of these structures. Finally, (...) we investigate the relationship between unsharp orthoalgebras, generalized MV algebras, and orthomodular lattices. (shrink)
