The Church-Turing thesis makes a bold claim about the theoretical limits to computation. It is based upon independent analyses of the general notion of an effective procedure proposed by Alan Turing and Alonzo Church in the 1930''s. As originally construed, the thesis applied only to the number theoretic functions; it amounted to the claim that there were no number theoretic functions which couldn''t be computed by a Turing machine but could be computed by means of some other kind of effective (...) procedure. Since that time, however, other interpretations of the thesis have appeared in the literature. In this paper I identify three domains of application which have been claimed for the thesis: (1) the number theoretic functions; (2) all functions; (3) mental and/or physical phenomena. Subsequently, I provide an analysis of our intuitive concept of a procedure which, unlike Turing''s, is based upon ordinary, everyday procedures such as recipes, directions and methods; I call them mundane procedures. I argue that mundane procedures can be said to be effective in the same sense in which Turing machine procedures can be said to be effective. I also argue that mundane procedures differ from Turing machine procedures in a fundamental way, viz., the former, but not the latter, generate causal processes. I apply my analysis to all three of the above mentioned interpretations of the Church-Turing thesis, arguing that the thesis is (i) clearly false under interpretation (3), (ii) false in at least some possible worlds (perhaps even in the actual world) under interpretation (2), and (iii) very much open to question under interpretation (1).

In her 2004 book Carol Gould addresses the fundamental issue of democratizing globalization, that is to say of finding ways to open transnational institutions and communities to democratic participation by those widely affected by their decisions. The book develops a framework for expanding participation in crossborder decisions, arguing for a broader understanding of human rights and introducing a new role for the ideas of care and solidarity at a distance. Reinterpreting the idea of universality to accommodate a multiplicity of (...) cultural perspectives, the author takes up a number of applied issues, including the persistence of racism, cultural rights, women's human rights, the democratic management of firms, the use of the Internet to enhance political participation, and the importance of empathy and genuine democracy in understanding terrorism and responding to it. Accessibly written with a minimum of technical jargon this is a major contribution to political philosophy. (shrink)

In the technical literature of computer science, the concept of an effective procedure is closely associated with the notion of an instruction that precisely specifies an action. Turing machine instructions are held up as providing paragons of instructions that "precisely describe" or "well define" the actions they prescribe. Numerical algorithms and computer programs are judged effective just insofar as they are thought to be translatable into Turing machine programs. Nontechnical procedures (e.g., recipes, methods) are summarily dismissed as ineffective on the (...) grounds that their instructions lack the requisite precision. But despite the pivotal role played by the notion of a precisely specified instruction in classifying procedures as effective and ineffective, little attention has been paid to the manner in which instructions "precisely specify" the actions they prescribe. It is the purpose of this paper to remedy this defect. The results are startling. The reputed exemplary precision of Turing machine instructions turns out to be a myth. Indeed, the most precise specifications of action are provided not by the procedures of theoretical computer science and mathematics (algorithms) but rather by the nontechnical procedures of everyday life. I close with a discussion of some of the rumifications of these conclusions for understanding and designing concrete computers and their programming languages. (shrink)

There is no broadly accepted definition of ‘life.’ Suggested definitions face problems, often in the form of robust counter-examples. Here we use insights from philosophical investigations into language to argue that defining ‘life’ currently poses a dilemma analogous to that faced by those hoping to define ‘water’ before the existence of molecular theory. In the absence of an analogous theory of the nature of living systems, interminable controversy over the definition of life is inescapable.

For feminists, working in/with the ‘posts’ is, always has been, and must be, a collective and collaborative endeavour. Increasingly, post-inquiry involves taking seriously multiplicities of humans, nonhumans, more-than-and-other-than-humans, multispecies and natureculture entities, including viral, microbial, elemental and atmospheric relationalities. The individual papers in this Special Issue, this editorial, and the Special Issue as a whole attest to this imperative pull to the collective-collaborative in seeking to explore the entangled relations of/between feminisms and the ‘posts’. As a collaborative-collective multiplicity, the Special (...) Issue interrogates what these entangled relations offer for reconfiguring gender and education research, theory, pedagogic practice, activism and praxis. (shrink)

The question ‘what is life?’ has long been a source of philosophical debate and in recent years has taken on increasing scientific importance. The most popular approach among both philosophers and scientists for answering this question is to provide a “definition” of life. In this article I explore a variety of different definitional approaches, both traditional and non-traditional, that have been used to “define” life. I argue that all of them are deeply flawed. It is my contention that a scientifically (...) compelling understanding of the nature of life presupposes an empirically adequate scientific theory (vs. definition) of life; as I argue, scientific theories are not the sort of thing that can be encapsulated in definitions. Unfortunately, as I also discuss, scientists are currently in no position to formulate even a tentative version of such a theory. Recent discoveries in biology and biochemistry have revealed that familiar Earth life represents a single example that may not be representative of life. If this is the case, life on Earth today provides an empirically inadequate foundation for theorizing about life considered generally. I sketch a strategy for procuring the needed additional examples of life without the guidance of a definition or theory of life, and close with an application to NASA’s fledgling search for extraterrestrial life.

The author compares myths about meat-eating with myths about manliness, and seeks to explore the literary, scientific, and social connections between meat-eating, male dominance, and war. Drawing on such sources as butchering texts, cookbooks, Victorian hygiene manuals, and Alice Walker, the author argues in favor of linking feminist and vegetarian theory.

: Despite its amazing morphological diversity, life as we know it on Earth today is remarkably similar in its basic molecular architecture and biochemistry. The assumption that all life on Earth today shares these molecular and biochemical features is part of the paradigm of modern biology. This paper examines the possibility that this assumption is false, more specifically, that the contemporary Earth contains as yet unrecognized alternative forms of microbial life. The possibility that more than one form of life arose (...) on Earth is consistent with our current understanding of conditions on the early Earth and the biochemical and molecular possibilities for life. Arguments that microbial descendents of an alternative origin of life could not co-exist with familiar life are belied by what we know of the complexity and diversity of microbial communities. Furthermore, the tools that are currently used to explore the microbial world – microscopy (with the aid of techniques such as DAPI staining and fluorescence in situ hybridization), cultivation and PCR amplification of rRNA genes – could not detect such organisms if they existed. Thus, the fact that we have not discovered any alternative life forms cannot be taken as evidence that they do not exist. (shrink)

Many scientists believe that there is a uniform, interdisciplinary method for the prac- tice of good science. The paradigmatic examples, however, are drawn from classical ex- perimental science. Insofar as historical hypotheses cannot be tested in controlled labo- ratory settings, historical research is sometimes said to be inferior to experimental research. Using examples from diverse historical disciplines, this paper demonstrates that such claims are misguided. First, the reputed superiority of experimental research is based upon accounts of scientific methodology (Baconian inductivism (...) or falsificationism) that are deeply flawed, both logically and as accounts of the actual practices of scientists. Second, although there are fundamental differences in methodology between experimental scien- tists and historical scientists, they are keyed to a pervasive feature of nature, a time asymmetry of causation. As a consequence, the claim that historical science is methodo- logically inferior to experimental science cannot be sustained. (shrink)

Seminal work by Knobe, Prasada, and Newman (2013) distinguished a set of concepts, which they named “dual‐character concepts.” Unlike traditional concepts, they require two distinct criteria for determining category membership. For example, the prototypical dual‐character concept “artist” has both a concrete dimension of artistic skills, and an abstract dimension of aesthetic sensibility and values. Therefore, someone can be a good artist on the concrete dimension but not truly an artist on the abstract dimension. Does this analysis capture people's understanding of (...) cornerstone social categories, such as gender, around which society and everyday life have traditionally been organized? Gender, too, may be conceived as having not only a concrete dimension but also a distinct dimension of abstract norms and values. As with dual‐character concepts, violations of abstract norms and values may result in someone being judged as not truly a man/woman. Here, we provide the first empirical assessment of applying the dual‐character framework to people's conception of gender. We found that, on some measures that primarily relied on metalinguistic cues, gender concepts did indeed resemble dual‐character concepts. However, on other measures that depicted transgressions of traditional gender norms, neither “man” nor “woman” appeared dual‐character‐like, in that participants did not disqualify people from being truly a man or truly a woman. In a series of follow‐up studies, we examined whether moral norms have come to replace gender role norms for the abstract dimension. Implications for the evolution of concepts and categories are explored. (shrink)

James B. Ashbrook's "new natural theology in an empirical mode" pursued an integrated understanding of the spiritual, psychological, and neurological dimensions of spiritual life. Knowledge of neuroscience and personality theory was central to his quest, and his understandings were necessarily revised and amplified as scientific findings emerged. As a result, Ashbrook's legacy may serve as a case example of how to do religion-and-science in a milieu of scientific change. The constant in the quest was Ashbrook's core belief in the basic (...) holism of brain, mind, personality, the nature of reality, and the underlying reality of God. (shrink)

[opening paragraph]: My comment will focus on the following five claims of Humphrey's. At some points I will be drawing on his book A History of the Mind as well as the target article in this issue.

Recent reports of the discovery of a “God module” in the human brain derive from the fact that epileptic seizures in the left temporal lobe are associated with ecstatic feelings sometimes described as an experience of the presence of God. The brain area involved has been described as either (a) the seat of an innate human faculty for experiencing the divine or (b) the seat of religious delusions.In fact, religious experience is extremely various and involves many parts of the brain, (...) including some that are prehuman in their evolutionary history and some that are characteristically human. In the continuing integration of such experiences, spiritual formation takes place. Thus the entire human brain might be described as a “God module.”Such a process is only possible because of the brain's complexity. The human brain is the most complex entity for its size that we know of. As used here, complexity is a specialized term denoting the presence of a web of interlinked and significant connections—the more intricate the web, the more complex the entity. Complex systems develop only in a milieu that provides both lawfulness and freedom, and they tend to be self‐organizing, becoming more complex and more effective as a result of both inward and outward experience. The evidence suggests that both personal growth and spiritual growth are processes of complexification of character, and of the brain itself. This thesis is tested in light of the work of William James and James W. Fowler. (shrink)

Eugene d’Aquili and Andrew B. Newberg's The Mystical Mind: Probing the Biology of Religious Experience presents a core theory regarding the neurophysical nature of mystical experience; extensions of this theory, focusing upon near‐death experiences and the nature of religion itself; and buttressing arguments proposing that genetically based neurophysical “operators” within the brain compel human beings to think in certain ways. On the basis of this work, the authors pose a “metatheology,” suggesting that certain brain operations may underlie all the religions (...) of the world. The core theory, its extensions, and related arguments are discussed in turn, concluding with commentary on the authors’ constructive theology. (shrink)

One of the central features of Western existence is the objectification and use of other beings in creating the subjectification of human beings. My argument is for a Christian veganism that rejects the dependence of the subject on the object status of other beings. The roadblocks to recognizing the necessity for Christian veganism I call the pedagogy of the oppressor. I propose that one way to change the subject-object relationship is a poetics of Christian engagement. Christian veganism may seem a (...) radical position theoretically and pragmatically, but I will offer suggestions for expanding Christian engagement with other animals and for the food and environmental justice movements of which veganism is a part.

Neuroscience is in a period of explosive growth. To address the implications of the new findings for religion and science, Zyvon in 1996 published fifteen articles in this field. Although the authors'explorations of neuroscience and religion are various, three issues in particular are addressed repeatedly: (1) the nature of human identity, or hallmarks of humanness; (2) the nature and origin of religious consciousness; and (3) our means of discovering or constructing order and integration in the brain/mind, in the environment, and (...) holistically. With these categories as templates, this article correlates the findings of the Zygon neuroscience contributors of 1996. (shrink)

Representing species-specific proteins and protein complexes in ontologies that are both human and machine-readable facilitates the retrieval, analysis, and interpretation of genome-scale data sets. Although existing protin-centric informatics resources provide the biomedical research community with well-curated compendia of protein sequence and structure, these resources lack formal ontological representations of the relationships among the proteins themselves. The Protein Ontology (PRO) Consortium is filling this informatics resource gap by developing ontological representations and relationships among proteins and their variants and modified forms. Because (...) proteins are often functional only as members of stable protein complexes, the PRO Consortium, in collaboration with existing protein and pathway databases, has launched a new initiative to implement logical and consistent representation of protein complexes. We describe here how the PRO Consortium is meeting the challenge of representing species-specific protein complexes, how protein complex representation in PRO supports annotation of protein complexes and comparative biology, and how PRO is being integrated into existing community bioinformatics resources. The PRO resource is accessible at http://pir.georgetown.edu/pro/. (shrink)

Since the mid-twentieth century, the concept of the Turing machine has dominated thought about effective procedures. This paper presents an alternative to Turing's analysis; it unifies, refines, and extends my earlier work on this topic. I show that Turing machines cannot live up to their billing as paragons of effective procedure; at best, they may be said to provide us with mere procedure schemas. I argue that the concept of an effective procedure crucially depends upon distinguishing procedures as definite courses (...) of action(- types) from the particular courses of action(-tokens) that actually instantiate them and the causal processes and/or interpretations that ultimately make them effective. On my analysis, effectiveness is not just a matter of logical form; `content' matters. The analysis I provide has the advantage of applying to ordinary, everyday procedures such as recipes and methods, as well as the more refined procedures of mathematics and computer science. It also has the virtue of making better sense of the physical possibilities for hypercomputation than the received view and its extensions, e.g. Turing's o-machines, accelerating machines. (shrink)

This paper explores the character of emotion and its value in understanding ethical dilemmas in work organisations. Specifically, we examine the emotional labour of human resource professionals. Through in-depth interviews and diary study, we uncover the emotional and ethical struggles of HRPs as they search for the ‘right thing to do’ in situated interaction. Through the lens of emotion, we chart the process of how the very framing of what is deemed ‘right’ can move from the social to the moral (...) order and vice versa. Based on our findings, we contribute to understanding the linkages between emotional and ethical dilemmas, and how expectations of multiple ‘others’ at the individual, interpersonal and organisational level shape and constrain ethical choices.

In times like these, a new ethico-political ideal is required to contest the adequacy of dominant understandings of social interaction as matters of choice and rational decision-making and in contesting these understandings encourage us to imagine social alternatives. We wish to make a contribution to this project of expanding the universe of political discourse as a means to invigorating ethico-political debate. A range of existing vocabularies — the languages of trust (and relatedly respect), care and associated concepts, including corporeal generosity (...) — are currently put forward as the means to contest the dominance of neo-liberal premises about `atomistic individualism'. While many of these accounts focus on nation-states, others attend to an emerging global community. Nevertheless, we have some reservations about these languages and their premises. In our view they tend frequently to locate the `problem' in the character of citizens. We also make the case that such languages and their associated political agendas reinstate aspects of social hierarchy that mimic neo-liberal conceptions of autonomous individualism. Central to our critique is the claim that the problematic aspects of these existing languages of (inter)connection are due to an attenuated understanding of embodiment and an inadequate dialogue between the socio-political and embodiment. It is this inadequate dialogue we wish to redress. In this paper we offer a new ethical ideal called `social flesh' to ground an alternative politics for reconfiguring exploitative social relations. As an ethico-political starting point, `social flesh' highlights human embodied interdependence and in the process configures a new, more transformative political vision. It draws attention to shared embodied reliance, mutual reliance, of people across the globe on social space, infrastructure and resources. Insistence upon this shared reliance underpins a profoundly levelling perspective, a radical politics. (shrink)

In settings ranging from an Athenian home to a Persian palace, Xenophon shows women engaging in dialogue and asserting a distinctive perspective that comments on their own position in society. It also illuminates their experience of being the objects of the male gaze and restricted in their social interactions. In using women such as Theodote, an Athenian courtesan (Memorabilia) and Pantheia, a non-Greek queen (Cyropaedia) to represent ethical positions and virtue itself, Xenophon both draws on and contests the Greek literary (...) heritage, and the depiction of women in genres ranging from epic and tragedy to historiography. He represents a broader Socratic tradition from that evident in Plato’s work, in which women were more often used as interlocutors. These women appear as participants in the project of philosophical reflection on the pursuit of virtue, not just as the objects of male discussion. (shrink)

In particular, The meaning of 'constitution' is analyzed, With the result that traditional realistic or idealistic readings of husserl are discarded. Examination of passive and active synthesis and the meaning of 'hyle' within the framework of husserl's theory of inner time-Consciousness clarifies in turn the nature of phenomenological intuition and the significance of reduction.

This paper has its genesis in concerns about the return to “the real” in social and political theory and analysis. This trend is linked to a reaction against the “linguistic turn”, on the grounds that an exclusive focus on language undercuts political analysis by refusing to engage with “material reality”. Foucault and “discourse” are common targets of this critique. Against this interpretation, the authors direct attention to the analytic and political usefulness of Foucault’s concept of “discursive practices”, which, it argues, (...) has been much misunderstood. Discursive practices, as developed by Foucault, refers to the practices of discourses, meaning knowledge formations, not to linguistic practices or language use. The focus is on how knowledge is produced through plural and contingent practices across different sites. Such an approach bridges a symbolic-material distinction and signals the always political nature of “the real”. (shrink)

Arguments in favor of legalized assisted suicide often center on issues of personal privacy and freedom of choice over one's body. Many disability advocates assert, however, that autonomy arguments neglect the complex sociopolitical determinants of despair for people with disabilities. Specifically, they argue that social approval of suicide for individuals with irreversible conditions is discriminatory and that relaxing restrictions on assisted suicide would jeopardize, not advance, the freedom of persons with disabilities to direct the lives they choose. This paper examines (...) the idea promoted by some proponents of assisted suicide that it is reasonable to be depressed about one's diminished quality of life in cases of irreversible illness or disability and, therefore, such depression should not call into question the individual's competence to request assistance in dying. The concept of rational depression is defined and examined in the context of: four real-life cases involving individuals with disabilities who requested assistance in dying; a set of criteria commonly applied to decision-making to determine rationality; and research bearing on the emotional status of people with disabilities. It is concluded that although disability is associated with particular socially mediated stressors, there is no theoretical or empirical evidence to indicate that depression and its role in the right to die is dynamically different, more natural, or more reasonable for disabled people than for non-disabled people.

A common early narrative that arose as people struggled to cope with their new lives under COVID-19 centered on a platitude about the pandemic being “the great leveler.” But the pretense that we are equally vulnerable—or that we’re “alone together” across lines of race, gender, and class—was a comforting lie. Chronicling the timeline of media talking points seen over the past few months, I argue that social privilege continues to structure the narratives many people use to process life under the (...) pandemic, even while material conditions are much worse for those not in charge of these narratives. At the same time, however, I argue that the pandemic might be setting the stage for genuinely new collective responses to social inequalities, including the long-overdue uprisings inspired by the Black Lives Matter movement.
