The ancient Stoics notoriously argued, with thoroughness and force, that all ordinary “emotions” (passions, mental affections: in Greek, pãyh) are thoroughly bad states of mind, not to be indulged in by anyone, under any circumstances: anger, resentment, gloating; pity, sympathy, grief; delight, glee, pleasure; impassioned love (i.e. ¶rvw), agitated desires of any kind, fear; disappointment, regret, all sorts of sorrow; hatred, contempt, schadenfreude. Early on in the history of Stoicism, however, apparently in order to avoid the objection that human nature (...) itself demands and indeed justifies—under certain circumstances at any rate—emotional attachments to or aversions from, and reactions to, some persons, things, and happenings, they introduced a theory of what came to be called eÈpãyeiai, good and acceptable ways of feeling or being affected. For short I will render these in English by “good feelings.”1 They divided these into three generic kinds, which they dubbed “joy” (xarã), “wish” (boÊlhsiw) and “caution” (eÈlãbeia). They ranged these alongside, and set them in sharp contrast to, three of the four highest genera into which they divided the normal human emotions: “pleasure” (≤donÆ), i.e., being pleased about something,2 “appetitive desire” (§piyuµ€a), and “fear” (fÒbow), respectively. The Stoics maintained that, though ordinary, familiar human emotions such as these last-named ones were always bad, the three sorts of “good feeling,” and their more specific variations (since these three are only the basic genera into which lots of other good ways of feeling will fall), were not merely free from the grounds of criticism on which ordinary emotions were rejected, and so were perfectly acceptable. The fully perfected human being (the “wise person”) would indeed regularly be subject to them. (shrink)

David Cooper explores and defends the view that a reality independent of human perspectives is necessarily indescribable, a "mystery." Other views are shown to be hubristic. Humanists, for whom "man is the measure" of reality, exaggerate our capacity to live without the sense of an independent measure. Absolutists, who proclaim our capacity to know an independent reality, exaggerate our cognitive powers. In this highly original book Cooper restores to philosophy a proper appreciation of mystery-that is what provides a (...) measure of our beliefs and conduct. (shrink)
Why do gardens matter so much and mean so much to people? That is the intriguing question to which David Cooper seeks an answer in this book. Given the enthusiasm for gardens in human civilization ancient and modern, Eastern and Western, it is surprising that the question has been so long neglected by modern philosophy. Now at last there is a philosophy of gardens. David Cooper identifies garden appreciation as a special human phenomenon distinct from both from the (...) appreciation of art and the appreciation of nature. He discusses the contribution of gardening and other garden-related pursuits to "the good life." And he distinguishes the many kinds of meanings that gardens may have, from their representation of nature to their spiritual significance. A Philosophy of Gardens will open up this subject to students and scholars of aesthetics, ethics, and cultural and environmental studies, and to anyone with a reflective interest in things horticultural.

The formal systems of logic have ordinarily been regarded as independent of biology, but recent developments in evolutionary theory suggest that biology and logic may be intimately interrelated. In this book, Cooper outlines a theory of rationality in which logical law emerges as an intrinsic aspect of evolutionary biology. This biological perspective on logic, though at present unorthodox, could change traditional ideas about the reasoning process. Cooper examines the connections between logic and evolutionary biology and illustrates how logical (...) rules are derived directly from evolutionary principles, and therefore have no independent status of their own. Laws of decision theory, utility theory, induction, and deduction are reinterpreted as natural consequences of evolutionary processes. Cooper's connection of logical law to evolutionary theory results in a unified foundation for an evolutionary science of reason. (shrink)

Cooper, Austin John Henry Newman was born in 1801, converted to the Catholic Church in 1845 and died in 1890. That is, he spent the first half of his life in the Church of England. He was to exercise a profound influence on both Communions in Australia. The young Newman was elected a Fellow of Oriel College, Oxford, in April 1822. Despite the declining fortunes of his family, his own career was off to a promising start. Two years later (...) he was ordained Deacon at Christ Church Cathedral, Oxford on 13 June 1824. This was a very solemn commitment indeed. He thought he should give himself totally to the service of the Gospel. This attitude prompted him to write to the CMS (the Church Missionary Society) in London seeking information regarding service as a missionary. He followed up his letter with a visit to the CMS London Headquarters on July 3, 1824 - just two weeks after his ordination as deacon. (shrink)
Cooper, Austin Christian Spirituality can be approached from numerous points on the theological compass: Sacred Scripture is an obvious source, but so are almost any of the theological disciplines. This paper will be concerned with it as emanating from Church History.
Christianity is deeply interested in the body. In its central mysteries - creation, incarnation, and resurrection - the body and human flesh are radically implicated. Bodies are persons, and persons are spiritual beings, bearers of the divine image and destined for bodily union with God. From the Bible to the Second Vatican Council, from Irenaeus and Tertullian to Aquinas and Luther, the classic sources of the Christian tradition engender a spiritual philosophy that challenges the ever-present gnostic impulse either to marginalize, (...) or else to worship, the body. Adam G. Cooper brings these rich sources into conversation with numerous contemporary voices in philosophy and theology, offering an illuminating and critical perspective on such pressing social and ethical questions as pornography, feminism, philosophy of mind, sterility, and death.

is a term introduced by Ian Hacking to refer to the kinds of people—child abusers, pregnant teenagers, the unemployed—studied by the human sciences. Hacking argues that classifying and describing human kinds results in feedback, which alters the very kinds under study. This feedback results in human kinds having histories totally unlike those of natural kinds (such as gold, electrons and tigers), leading Hacking to conclude that human kinds are radically unlike natural kinds. Here I argue that Hacking's argument fails and (...) that he has not demonstrated that human kinds cannot be natural kinds.

An inventory of major studies between 1986 and 2006 indicates the public has continuing and in some cases increasing concerns about specific ethical practices in the mass media industries. While some concerns such as deception, invasion of privacy, advertising saturation, and excessive violence apply to multiple channels of communication, others are medium specific. For example, the public's primary anxieties about the Internet include fraud, spam, and the availability of pornography to children, while the primary concerns about telephone have included telemarketing (...) and wiretapping. Overall findings suggest several substantial and escalating concerns such as the erosion of press credibility and trust in the media at large. These findings proved consistent with a recent national poll commissioned for the second U.S. Media Ethics Summit conference. (shrink)
Increasingly, Deaf activists claim that it can be good to be Deaf. Still, much of the hearing world remains unconvinced, and continues to think of deafness in negative terms. I examine this debate and argue that to determine whether it can be good to be deaf it is necessary to examine each claimed advantage or disadvantage of being deaf, and then to make an overall judgment regarding the net cost or benefit. On the basis of such a survey I conclude (...) that being deaf may plausibly be a good thing for some deaf people but not for others. (shrink)
There is a long history of controversy in ecology over the role of competition in determining patterns of distribution and abundance, and over the significance of the mathematical modeling of competitive interactions. This paper examines the controversy. Three kinds of considerations have been involved at one time or another during the history of this debate. There has been dispute about the kinds of regularities ecologists can expect to find, about the significance of evolutionary considerations for ecological inquiry, and about the (...) empirical credentials of theoretical studies of competition. Each of these elements is examined with an eye toward gaining philosophical clarification of the issues involved. In the process, certain shortcomings of contemporary philosophical theories are revealed. In particular, I argue that plausibility arguments based on background considerations are an important part of the model building tradition, but that current accounts of the structure and evaluation of scientific theories do little to illuminate this side of theoretical ecology.

The paper asks whether gardens may be objects of ‘serious’ (in Ronald Hepburn's sense) and distinctive appreciation. Dismissive attitudes to the possibility of such appreciation, including Hegel's, are rejected, as is the view—Kant's, for example—that garden appreciation is ‘factorizable’ into the modes appropriate for artworks and ‘raw’ nature respectively. That view entails that there is nothing distinctive in garden appreciation. Attention then turns to the idea that it is the representational/symbolic capacities of gardens that render them objects of distinctive appreciation. (...) That idea is criticized, but a related one, appealing to more ‘penumbral’ semantic notions like evocation, is defended. It is argued, in particular, that gardens may distinctively evoke the ‘creative receptivity’, to cite Gabriel Marcel, of human beings. Gardens, more perhaps than any other artworks, vividly testify to the dependence of their makers on what is beyond human artifice and control. (shrink)
The balance of nature concept is an old idea that manifests itself in anumber of forms in population and community ecology. This paper focuseson population ecology, where controversy surrounding the balance ofnature takes the form of perennial debates over the significance ofdensity dependence, population regulation, and species interactions suchas competition. One of the most striking features of these debates, overthe course of the previous century in ecology, is the tendency to arguethe case on largely conceptual grounds. This paper explores twoquestions. (...) Why this tendency to settle on conceptual grounds what is soobviously an empirical issue? Are there any good conceptual arguments tobe had in this area?

A rational reconstruction of James's doctrine of pure experience is attempted, showing how it can be formulated in terms of a Ramsey sentence so that its credibility is comparable to contemporary functionalism about the mind. Whereas functionalism treats only mental predicates as theoretical terms and quantifies over physical objects, Jamesian 'global-functionalism' treats both mental and physical predicates as theoretical terms and quantifies over pure experience. Rehabilitated in this way, the doctrine of pure experience is a fit partner for Jamesian <span (...) class='Hi'>pragmatism</span>. When James says that <span class='Hi'>pragmatism</span> guides us in the course of our experience, this 'experience' must be understood as ultimately pure experience. Pure experience is just what appears , pre-conceptually, and Ramsey-sentence analysis shows how James's employment of the pre-conceptual demonstrative that can refer to pure experience with conditions of identity given by its physical or mental properties, while being itself 'colourless', neither mental nor physical. It is concluded that functionalists about the mind have reason to be global-functionalists about mind and body, in just the way that James's doctrine of pure experience lays out; and Jamesian pragmatists should also accept his radical empiricism.

The division between “erklaren” and “verstehen” is not as sharp as the conventional wisdom maintains, for all understanding, including the understanding of people, consists in the connecting, ordering and appraising of things encountered, believed or known. The understanding of people is a distinctive kind of cognitive understanding which has a practical side, involving the emotions. The education of the emotions, needed for us to understand ourselves and others, can be achieved both by the observation of real life and importantly by (...) the study of realistic fiction and of biography.

Cognitive architectures - task-general theories of the structure and function of the complete cognitive system - are sometimes argued to be more akin to frameworks or belief systems than scientific theories. The argument stems from the apparent non-falsifiability of existing cognitive architectures. Newell was aware of this criticism and argued that architectures should be viewed not as theories subject to Popperian falsification, but rather as Lakatosian research programs based on cumulative growth. Newell's argument is undermined because he failed to demonstrate (...) that the development of Soar, his own candidate architecture, adhered to Lakatosian principles. This paper presents detailed case studies of the development of two cognitive architectures, Soar and ACT-R, from a Lakatosian perspective. It is demonstrated that both are broadly Lakatosian, but that in both cases there have been theoretical progressions that, according to Lakatosian criteria, are pseudo-scientific. Thus, Newell's defense of Soar as a scientific rather than pseudo-scientific theory is not supported in practice. The ACT series of architectures has fewer pseudo-scientific progressions than Soar, but it too is vulnerable to accusations of pseudo-science. From this analysis, it is argued that successive versions of theories of the human cognitive architecture must explicitly address five questions to maintain scientific credibility. (shrink)
There has been a significant amount of uncertainty and controversy over the prospects for general knowledge in ecology. Environmental decision makers have begun to despair of ecology's capacity to provide anything more than case by case guidance for the shaping of environmental policy. Ecologists themselves have become suspicious of the pursuit of the kind of genuine nomothetic knowledge that appears to be the hallmark of other scientific domains. Finally, philosophers of biology have contributed to this retreat from generality by suggesting (...) that there really are no laws in biology. This paper addresses these issues by providing a framework for thinking about general knowledge claims in ecology. It introduces a philosophical taxonomy that classifies generalizations into three broad categories – phenomenological, causal and theoretical. It then turns to the difficult problem of laws, arguing that, while there are probably no laws as that term has been understood in philosophy of science, it doesn't follow that everything in ecology is equally contingent. A mechanism for recognizing degrees of contingency in ecological generalizations is developed. The paper concludes by examining the implications of the analysis for the controversies noted at the outset. (shrink)
Arguably, every new technology creates hidden ejfects in its environment, rearranging the social order it penetrates. Many ofthese effects are inextricably linked to ethical issues. Some are eternal issues such as censorship andfree speech, but others have new names and dimensions, and may even be new issues. Forty of these issues pertaining to the new communication technologies of the 1990s and next millennium are catalogued here. The author argues that each new communication technology either retrieves, amplifies, transforms, obsolesces, or mixes (...) ethical issues from the past or creates new issues for the future. However, as in the Ross Hume Hall (1974) effect, it is also likely there are issues yet unknown due to untested eflects of combining new technologies. (shrink)
Recent controversy over the existence of biological laws raises questions about the cognitive aims of theoretical modeling in that science. If there are no laws for successful theoretical models to approximate, then what is it that successful theories do? One response is to regard theoretical models as tools. But this instrumental reading cannot accommodate the explanatory role that theories are supposed to play. Yet accommodating the explanatory function, as articulated by Brandon and Sober for example, seems to involve us once (...) again in a reliance on laws. The paper concludes that we must rethink both the nature of laws and theoretical explanation in biology. (shrink)
The paper investigates an elliptical construction, Clarification Ellipsis, that occurs in dialogue. We suggest that this provides data that demonstrates that updates resulting from utterances cannot be defined in purely semantic terms, contrary to the prevailing assumptions of existing approaches to dynamic semantics. We offer a computationally oriented analysis of the resolution of ellipsis in certain cases of dialogue clarification. We show that this goes beyond standard techniques used in anaphora and ellipsis resolution and requires operations on highly structured, linguistically (...) heterogeneous representations. We characterize these operations and the representations on which they operate. We offer an analysis couched in a version of Head-Driven Phrase Structure Grammar combined with a theory of information states (IS) in dialogue. We sketch an algorithm for the process of utterance integration in IS which leads to grounding or clarification. The account proposed here has direct applications to the theory of attitude reports, an issue which is explored briefly in the concluding remarks of the paper. (shrink)
A fundamental philosophical question that arises in connection with evolutionary theory is whether the fittest patterns of behavior are always the most rational. Are fitness and rationality fully compatible? When behavioral rationality is characterized formally as in classical decision theory, the question becomes mathematically meaningful and can be explored systematically by investigating whether the optimally fit behavior predicted by evolutionary process models is decision-theoretically coherent. Upon investigation, it appears that in nontrivial evolutionary models the expected behavior is not always in (...) accord with the norms of the standard theory of decision as ordinarily applied. Many classically irrational acts, e.g. betting on the occurrence of one event in the knowledge that the probabilities favor another, can under certain circumstances constitute adaptive behavior.One interesting interpretation of this clash is that the criterion of rationality offered by classical decision theory is simply incorrect (or at least incomplete) as it stands, and that evolutionary theory should be called upon to provide a more generally applicable theory of rationality. Such a program, should it prove feasible, would amount to the logical reduction of the theory of rational choice to evolutionary theory. (shrink)
This paper discusses how to use cognitive developmental psychology to create a business ethics course that has philosophical integrity. It begins with the pedagogical problem to be overcome when students are not philosophy majors. To provide a context for the practical recommendations, Kohlberg's cognitive developmental theory is summarized and then the relationship between Kohlberg's theory, normative philosophy, and teaching is analyzed. The conclusion recommends strategies that should help overcome some of the vexing pedagogical problems mentioned in the first section. In (...) particular, the approach is designed to teach an appreciation for the practical necessity of philosophy in a pluralistic society. (shrink)
Reviews show that comprehensive studies of international media ethics are necessarily incomplete because not all countries have either media codes or comparable measurement instruments. This article reviews major studies of international and national approaches to media ethics and describes contexts for global studies and comparisons. The three likely universals of truth, responsibility, and the drive for free expression are hypothesized, and codes are explored to see which patterns endured.
. This paper presents the findings of two surveys conducted in April 2003 of Chartered Life Underwriters (CLUs) and Chartered Financial Consultants (ChFCs) who are members of the Society of Financial Service Professionals. The first survey of 3000 CLUs and ChFCs – the life insurance industry’s most highly regarded professionals – was aimed at identifying the key ethical issues faced by professionals working in the life insurance industry today. A comparison of these findings with those of earlier studies conducted in (...) 1990 and 1995 suggests that while the key ethical issues facing those working in the life insurance business today are essentially the same as those encountered during industry’s highly troubled ethical environment of the early 1990s, these issues are perceived as presenting somewhat less serious problems than in the past. The second survey of 3000 CLUs and ChFCs was aimed at determining the extent to which these professionals perceive the industry created Insurance Marketplace Standards Association (IMSA) as having contributed to any change in the ethical environment that has taken place. The findings suggest that IMSA has played an important role in influencing senior managers to more strongly encourage and support ethical market conduct, a critical step in improving the industry’s ethical environment.

Burning fossil fuel in the North American continent contributes more to the CO2 global warming problem than in any other continent. The resulting climate changes are expected to alter food production. The overall changes in temperature, moisture, carbon dioxide, insect pests, plant pathogens, and weeds associated with global warming are projected to reduce food production in North America. However, in Africa, the projected slight rise in rainfall is encouraging, especially since Africa already suffers from severe shortages of rainfall. For all (...) regions, a reduction in fossil fuel burning is vital. Adoption of sound ecological resource management, especially soil and water conservation and the prevention of deforestation, is important.

Sober (1992) has recently evaluated Brandon's (1982, 1990; see also 1985, 1988) use of Salmon's (1971) concept of screening-off in the philosophy of biology. He critiques three particular issues, each of which will be considered in this discussion.
Based on the findings of several research studies of professionals in both the property-liability insurance industry and the life insurance industry, the paper makes and supports several important points. First, ethical challenges in the insurance industry involve not only a series of ethical dilemmas frequently faced by those working in the business, but also a variety of factors that hinder those working in the industry as they seek to resolve the ethical dilemmas encountered in the course of their work. Both (...) of these two components of ethical challenges must be understood by those in the financial services industry who will deal with insurance operations in the future. Second, whereas the life insurance business and the property-liability insurance business have traditionally been viewed as being quite different from one another and still are in terms of operations and regulation, the research findings show that they are no longer very different in terms of the key ethical challenges faced by those working in the two segments of the industry. The paper shows how during the past decade the ethical challenges in the property-liability insurance industry have become quite similar to those in the more troubled life insurance industry.

This paper examines several key aspects of the ethical environment facing the insurance industries of Poland, The Czech Republic and Hungary as they complete the transition from Communist insurance systems built upon state-owned monopolies to viable private domestic insurance markets, and then seek to harmonize their markets with the single insurance market of the European Union.

This paper shows how a dialogue system for information-seekingdialogues can be implemented in a type-theory-based syntax editor,originally developed for editing mathematical proofs.The implementation gives a simple logical metatheory tosuch dialogue systems and also suggests new functions forthem, e.g., a local undo operation. The method developed provides alogically based declarative way of implementing simple dialoguesystems that is easy to port to new domains.
Because physicians use scientific inference for the generalizations of individual observations and the application of general knowledge to particular situations, the Bayesian probability solution to the problem of induction has been proposed and frequently utilized. Several problems with the Bayesian approach are introduced and discussed. These include: subjectivity, the favoring of a weak hypothesis, the problem of the false hypothesis, the old evidence/new theory problem and the observation that physicians are not currently Bayesians. To the complaint that the prior probability (...) is subjective, Bayesians reply that there will be ultimate convergence, but the rebuttal to this is that there will not be uniform convergence. Secondly, since the Bayesian scheme favors a weak hypothesis, theories turn out to be a gratuitous risk. The problem with the false hypothesis comes out in the denominator of the theorem, revealing that a factor which is not a theory at all is being considered in the reasoning. On the old evidence/new theory problem old evidence cannot confirm a new theory so that the posterior probability will equal the prior probability. Finally, empiric studies have shown that current physicians are not Bayesians. But on consideration of Bayesian inference as a system of inference, it can be reasoned that physicians should be Bayesians. However, the problem of physicians' and patients' own subjectivity continue to plague this system of medical decision making. (shrink)

This claim causes difficulties, as traditionally Wittgensteinians have taken it to be the case that other forms of life are incomprehensible to us.

Commonalities among the findings for these rather diverse groups are highlighted and their possible implications for business and the professions (...) are discussed. (shrink)
The purpose of this essay is to argue for the necessity of an ethics of the practice of the specialist-technologist in medicine. In the first part I sketch three stages of medical ethics, each with a particular viewpoint regarding the technology of medicine.

Next, the philosophy of Heidegger is examined to suggest (...) an approach to the problem, and, finally, some of Levinas' contributions regarding the other are introduced to suggest a preliminary approach to a medical ethics of the specialist-technologist.

To develop critical thinking skills, higher order ethical reasoning, a better grasp of the implications of ethical decisions, and a basis for ethical knowledge, it is necessary to explore the philosophical premises foundational to one’s ethical persuasion. No philosophical premises are more important than those pertaining to the nature of human personhood and business’ responsibility to respect the inherent value of human beings. Philosophical naturalism assigns the essence of human personhood strictly to causal interactions of physical matter. Substance dualism, on (...) the other hand, posits both a physical aspect and an immaterial substance to personhood, interacting within the totality of each being. This paper argues for the logical superiority of substance dualism in achieving the overriding objective of discerning ethical knowledge. Substance dualism offers a better explanation – and one that more closely follows the way most people commonly experience themselves and others–than naturalism for free agency and accountability, meaningful moral standards, confidence in knowing what ethical decisions to make, and the moral drive residing in conscience.

A critical aspect of much human behaviour is the generation and regulation of sequential activities. Such behaviour is seen in both naturalistic settings such as routine action and language production and laboratory tasks such as serial recall and many reaction time experiments. There are a variety of computational mechanisms that may support the generation and regulation of sequential behaviours, ranging from those underlying Turing machines to those employed by recurrent connectionist networks. This paper surveys a range of such mechanisms, together (...) with a range of empirical phenomena related to human sequential behaviour. It is argued that the empirical phenomena pose difficulties for most sequencing mechanisms, but that converging evidence from behavioural flexibility, error data arising from when the system is stressed or when it is damaged following brain injury, and between-trial effects in reaction time tasks, point to a hybrid symbolic activation-based mechanism for the generation and regulation of sequential behaviour. Some implications of this view for the nature of mental computation are highlighted. (shrink)
