First published in 1986, Knowledge, Belief, and Witchcraft remains the only analysis of indigenous discourse about an African belief system undertaken from within the framework of Anglo-American analytical philosophy. Taking as its point of departure W. V. O. Quine's thesis about the indeterminacy of translation, the book investigates questions of Yoruba epistemology and of how knowledge is conceived in an oral culture.

There is currently a debate over whether cognitive architecture is classical or connectionist in nature. One finds the following three comparisons between classical architecture and connectionist architecture made in the pro-connectionist literature in this debate: (1) connectionist architecture is neurally plausible and classical architecture is not; (2) connectionist architecture is far better suited to model pattern recognition capacities than is classical architecture; and (3) connectionist architecture is far better suited to model the acquisition of pattern recognition capacities by learning than (...) is classical architecture. If true, (1)-(3) would yield a compelling case against the view that cognitive architecture is classical, and would offer some reason to think that cognitive architecture may be connectionist. We first present the case for (1)-(3) in the very words of connectionist enthusiasts. We then argue that the currently available evidence fails to support any of (1)-(3). (shrink)

Drawing from the Boulding''s (1956) framework for general systems theory, the need to employ richer paradigm in the study of organizations (Pondy and Mitroff, 1979) is reiterated. It is argued that a better understanding of organizational ethical behavior is contingent upon viewing organizations as symbol processing systems of shared language and meanings. Further, it is proposed that organizations, like individuals, develop into collectivities of shared cognitions and rationale, over a period of time. The study adapts Kohlberg''s (1983) model of moral (...) development to examine if organizations can be viewed as passing through different stages of moral development depending on the type of moral reasoning employed to explain their behaviors in the face of ethical crises. Several cases raising questions about the ethics of corporate behavior were researched. An instrument entitled Organization Response Analysis was constructed using statements made by various spokespersons representing five of these organizations. The instrument was administered to 246 graduate and undergraduate students of business (N = 246). Results indicated a great degree of concurrence among respondents of differing genders, levels of education and work experience in determining the stages of moral development of organizations. Limitations of the current study and implications for future research and practice are discussed. (shrink)

Cognitive Task Analysis (CTA) helps researchers understand how cognitive skills and strategies make it possible for people to act effectively and get things done. CTA can yield information people needemployers faced with personnel issues, market researchers who want to understand the thought processes of consumers, trainers and others who design instructional systems, health care professionals who want to apply lessons learned from errors and accidents, systems analysts developing user specifications, and many other professionals. CTA can show what makes the workplace (...) workand what keeps it from working as well as it might.Working Minds is a true handbook, offering a set of tools for doing CTA: methods for collecting data about cognitive processes and events, analyzing them, and communicating them effectively. It covers both the "why" and the "how" of CTA methods, providing examples, guidance, and stories from the authors' own experiences as CTA practitioners. Because effective use of CTA depends on some conceptual grounding in cognitive theory and researchon knowing what a cognitive perspective can offerthe book also offers an overview of current research on cognition.The book provides detailed guidance for planning and carrying out CTA, with chapters on capturing knowledge and capturing the way people reason. It discusses studying cognition in real-world settings and the challenges of rapidly changing technology. And it describes key issues in applying CTA findings in a variety of fields. Working Minds makes the methodology of CTA accessible and the skills involved attainable. (shrink)

Tensism holds that the present moment has a special status that sets it apart from the past and the future, independently of perceivers. One of the main objections to this view has been Einstein’s argument from special relativity, which aims at showing that absolute simultaneity is a myth. We argue that the moving observer in a causal variant of Einstein’s original thought experiment is subject to a temporal illusion. Owing to the analogy of the cases, this casts doubt on the (...) conjectures that there is no privileged frame of reference and that special relativity poses a problem for tensism. (shrink)

While the question of free will does not figure as prominently in Buddhist writings as it does in western theology, philosophy, and psychology, it is a topic that was addressed in the earliest Buddhist writings. According to these accounts, for pragmatic and ethical reasons, the Buddha rejected both determinism and indeterminism as understood at that time. Rather than asking the metaphysical question of whether already humans have free will, Buddhist tradition takes a more pragmatic approach, exploring ways in which we (...) can acquire greater freedom to make wise choices that are truly conducive to our own and others' genuine well-being. One key to achieving such freedom is the cultivation of attentional skills so that one can deliberately focus one's attention with continuity and clarity on one's chosen object. A second theme is the cultivation of insight into the manner in which our own attitudes shape experience, allowing for the possibility of altering not only the way we experience events in the present, but also how we are influenced by our memories of the past. Finally, the Great Perfection school of Tibetan Buddhism emphasizes the realization of the deepest dimension of consciousness -- pristine awareness -- which transcends the nexus of causality. This is regarded as the ultimate source of freedom and the ultimate nature of human identity. (shrink)

The need to make young scientists aware of their social responsibilities is widely acknowledged, although the question of how to actually do it has so far gained limited attention. A 2-day workshop entitled “Prepared for social responsibility?” attended by doctoral students from multiple disciplines in climate science, was targeted at the perceived needs of the participants and employed a format that took them through three stages of ethics education: sensitization, information and empowerment. The workshop aimed at preparing doctoral students to (...) manage ethical dilemmas that emerge when climate science meets the public sphere (e.g., to identify and balance legitimate perspectives on particular types of geo-engineering), and is an example of how to include social responsibility in doctoral education. The paper describes the workshop from the three different perspectives of the authors: the course teacher, the head of the graduate school, and a graduate student. The elements that contributed to the success of the workshop, and thus make it an example to follow, are (1) the involvement of participating students, (2) the introduction of external expertise and role models in climate science, and (3) a workshop design that focused on ethical analyses of examples from the climate sciences.

The copy provided on ths site is a late draft. It provides a philosophical argument for the view that by and large it is morally wrong to buy shares in a company that is behaving badly unless you (if necessary acting together with others) are able and willing to prevent the misbehaviour. A key lemma in my argument concerns a chain of authorisation from the shareholders to the company's board to the CEO -- one in virtue of which shareholders are (...) ultimately responsible for major patterns of wrongdoing by the company.

The contextualist epistemological theories proposed by David Lewis and othersoffer a view of knowledge which awards a central role to the contexts ofknowledge attributions. Such contexts are held to determine how strong anepistemic position must be in order to count as knowledge. Lewis has suggestedthat contextualism so construed can be used both to ward off the skeptic and tosolve the Gettier problem. A person knows P, he says, just in case her evidenceeliminates every possibility that not-P, where the domain of (...) `every' is determinedby the context. Lewis provides a list of rules that can tell us, for a given context,which not-P possibilities must be eliminated and which can properly be ignored.But his account entails, counterintuitively, that knowledge can truly be attributedeven to a person in a Gettier situation provided only that the attributor is ignorantof the fact that the person is gettiered. It has been criticized on those grounds byS. Cohen. In this paper I shall argue that most other forms of contextualism sufferthe same fate as Lewis's. The allies of contextualism haven't yet shown us whethercontextualism can succeed in maintaining a notion of ordinary knowledge whileresisting the absurdity that knowledge can be a matter of sheer good luck. At theend of the paper I shall suggest a possible solution to the problem by showing howCohen's line of criticism leads to a modified conception of what sort of justificationa belief must have to count as knowledge in ordinary contexts.

The greatest contemporary challenge in the arena of cognitive neuroscience concerns the relation between consciousness and the brain. Over recent years the focus of work in this area has switched from the analysis of diverse spatial regions of the brain to that of the timing of neural events. It appears that two conditions are necessary in order for neural events to become correlated with conscious experience. First, the firing of assemblies of neurones must achieve a degree of coherence, and, second, (...) reflexive (i.e. top-down, or reentrant) neural pathways must be activated. It does not, of course, follow that such neural activity causes consciousness; it may be, for example, that the neural activity formats the brain to interact with consciousness. The latter possibility is suggested by analysis of mystical texts suggesting that coherence and reflexivity constitute the conditions for the influx of “spirit.” Kabbalistic sources, for example, describe a hierarchy of “brains” in the human and divine realms through which the principles of coherence and reflexivity operate. Whilst the ontological assumptions of such a scheme place it beyond the realm of psychology, parallels with the picture deriving from the contemporary cognitive neuroscience of consciousness are striking.

We define a property for varieties V, the f.r.p. . If it applies to a finitely based V then V is strongly finitely based in the sense of [14], see Theorem 2. Moreover, we obtain finite axiomatizability results for certain propositional logics associated with V, in its generality comparable to well-known finite base results from equational logic. Theorem 3 states that each variety generated by a 2-element algebra has the f.r.p. Essentially this implies finite axiomatizability of a 2-valued logic in (...) any finite language. (shrink)

In its most basic form, Simple Reliabilism states that: a belief is justified iff it is formed as the result of a reliable belief-forming process. But so-called New Evil Demon cases have been given as counterexamples. A common response has been to complicate reliabilism from its simplest form to accommodate the basic reliabilist position, while at the same time granting the force of NED intuitions. But what if despite initial appearances, Simple Reliabilism, without qualification, is compatible with the NED intuition? (...) What we can call the Dispositionalist Response to the New Evil Demon problem is fascinating because it contends just that: Simple Reliabilism is fully compatible with the NED intuition. It is claimed that all we need to do to recognize their compatibility is appreciate that reliability is a dispositional property. In this paper I shall critically evaluate the Dispositionalist proposal. (shrink)

This article examines the Kantian thesis of the a priori nature of our knowledge of space. Because it makes the representation of objects possible as external to us and all others, and consequently, as distinct and individualized, space (whatever its structure may be) claims the status as necessary condition and as apriori possibility of all knowledge. However, in the light of various physical, psychological and philosophical considerations, it seems that the particular structure allocated by Kant to space (i.e. uniqueness, infinity, (...) continuity, homogeneity, isotropy, Euclidean character and three-dimensional character) is neither necessary nor a priori but is rather contingent and dependent on experience. For this reason a pragmatist relativization of the transcendental approach appears to be necessary: the structure of space which makes knowledge possible is not apriori in an absolute sense, but rather, it is determined within the context of a certain practice, which is characterized by a certain mode of interaction with the environment and reveals particular empirical constraints to which this spatial structure must fit.

Abortion is an especially salient issue for considering the general problematic of religiously based conversation in the public square. It remains deeply divisive, fully thirty-four years after Roe v. Wade. Such divisiveness cannot be interpreted as merely an expression of profound differences between “secular” and “religious” voices, because differences also emerge among Christian denominations, reflecting different sources of moral authority, different accounts of moral discernment, and different judgments about the appropriate relations between law and morality in the context of pluralism. (...) As this paper explores, however, despite those differences, a generally identifiable “Christian” position concerning the moral status of abortion can be distinguished from secular philosophical judgments on the issue, which is important for Christian engagement with public policy debate.

The dynamics of single populations up to ecosystems, are often described by one or a set of non-linear ordinary differential equations. In this paper we review the use of bifurcation theory to analyse these non-linear dynamical systems. Bifurcation analysis gives regimes in the parameter space with quantitatively different asymptotic dynamic behaviour of the system. In small-scale systems the underlying models for the populations and their interaction are simple Lotka-Volterra models or more elaborated models with more biological detail. The latter ones (...) are more difficult to analyse, especially when the number of populations is large. Therefore for large-scale systems the Lotka-Volterra equations are still popular despite the limited realism. Various approaches are discussed in which the different time-scale of ecological and evolutionary biological processes are considered together. (shrink)

Mill contends that the fullest publicity and freedom of discussion is essential for all citizens to share in political freedom. Previous commentators have focused on Mill's strictures against censorship; they have paid little attention to his understanding of how freedom of discussion and political will formation are mediated in the public sphere by the distribution of social power in civil society, particularly control of the means of communication. This article shows that Mill's account of the sociology and political economy of (...) how public opinion forms is central to his understanding of freedom of discussion and democratic political freedom.

The scope of the thermodynamic theory of nonlinear irreversible processes is widened to include the nonlinear stability analysis of system motion. The emphasis is shifted from the analysis of instantaneous energy flows to that of the average work performed by periodic nonlinear processes. The principle of virtual work separates dissipative and conservative forces. The vanishing of the work of conservative forces determines the natural period of oscillation. Stability is then determined by the variations of the dissipative forces with amplitude of (...) oscillation. If the work is a minimum, under certain conditions, the motion is stable. Reduction to linear analysis shows the coincidence with the impedance analysis of electrical circuit theory. The theory is applied to the analysis of temporal interactions of nonlinear irreversible processes in the particular cases of synchronization and hysteresis. Characteristic nonequilibrium phenomena of directional energy transfers, self-excitation, system passivity, wave modulation, and “beat” phenomena are observed. Possible relationships with biological processes are discussed. (shrink)

Multifactorial analyses of data from representative British and German national contraception surveys were used to examine the principal demographic determinants of contraceptive use by women. Contraceptive use appeared to be determined mainly by reference to ‘reproductive status’. Women who were postponing pregnancies were using oral contraceptives, whereas those who wanted no more children relied more on intrauterine devices or sterilisation. Differences between the countries suggested that the choice of contraceptive method was influenced by health care policy, the organisation of the (...) relevant services and differential provider preferences. The contraceptive method used was also related to having occasional rather than steady sexual partners, lower educational level and frequent church attendance. Contraception decisions appeared to follow a fixed pattern, based more on a couple's demographic situation than on the characteristics of the contraceptive methods. This resulted in an unnecessarily restricted choice of methods. (shrink)

This paper argues that self-consciousness and associated psychic consciousness emerges as a consequence of a recursive selfdirecting on itself of the cognitive centre in the human brain. The neural mechanisms and circuits underlying self-consciousness appeared and developed during biological evolution as an adaptation that increased the fitness of our social ancestors, chances of their survival, and reproduction. These mechanisms/circuits strengthened the efficiency of individuals in various social relations, enabled separation of 'I' from 'he/she' or 'them' and the formation of firstand (...) higher-order theory of mind, stimulated development of complex, recursive language, facilitated forming temporary coalitions directed to achieve a particular goal, helped to establish social hierarchies, and increased coherence and cooperativity of a social group. The reciprocal reinforcement of the development of the neural network in the brain underlying self-consciousness and of the network of various social relations and aspects was a self-driving process, one of positive feedbacks abundant in anthropogenesis.
