Ethics position theory (EPT) maintains that individuals’ personal moral philosophies influence their judgments, actions, and emotions in ethically intense situations. The theory, when describing these moral viewpoints, stresses two dimensions: idealism (concern for benign outcomes) and relativism (skepticism with regards to inviolate moral principles). Variations in idealism and relativism across countries were examined via a meta-analysis of studies that assessed these two aspects of moral thought using the ethics position questionnaire (EPQ; Forsyth, Journal of Personality and Social Psychology 39 , (...) 175–184, 1980). This review identified 139 samples drawn from 29 different countries, for a total sample of 30,230 respondents, and concluded that (a) levels of idealism and relativism vary across regions of the world in predictable ways; (b) an exceptionist ethic is more common in Western countries, subjectivism and situationism in Eastern countries, and absolutism and situationism in Middle Eastern countries; and (c) a nation’s ethics position predicted that country’s location on previously documented cultural dimensions, such as individualism and avoidance of uncertainty (Hofstede, Culture’s Consequences: International Differences in Work-Related Values , 1980). Limitations in these methods and concerns about the validity of these cross-cultural conclusions are noted, as are suggestions for further research using the EPQ. (shrink)
Kitcher and Aspray distinguish a mainstream tradition in the philosophy of mathematics concerned with foundationalist epistemology, and a ‘maverick’ or naturalistic tradition, originating with Lakatos. My claim is that if the consequences of Lakatos's contribution are fully worked out, no less than a radical reconceptualization of the philosophy of mathematics is necessitated, including history, methodology and a fallibilist epistemology as central to the field. In the paper an interpretation of Lakatos's philosophy of mathematics is offered, followed by some critical discussion, (...) and an extension to a social constructivist position (which might well have been unacceptable to Lakatos).

Mathematicians and physical scientists depend heavily on the formal symbolism of mathematics in order to express and develop their theories. For this and other reasons the last hundred years has seen a growing interest in the nature of formal language and the way it expresses meaning; particularly the objective, shared aspect of meaning as opposed to subjective, personal aspects. This dichotomy suggests the question: do the objective philosophical theories of meaning offer concepts which can be applied in psychological theories of (...) meaning? In recent years cognitive scientists such as Chomsky [1980], Fodor [1981] and MacNamara [1982] have used philosophical approaches to the meaning of formal language expressions as the basis for their psychological theories. Following this lead it seems appropriate to review some of the main treatments of meaning with a view to their transferability. (shrink)
The objective of the OSCAR Project is twofold. On the one hand, it is to construct a general theory of rational cognition. On the other hand, it is to construct an artificial rational agent (an "artilect") implementing that theory. This is a joint project in philosophy and AI.
Leading Harvard philosophy professor William Ernest Hocking (1873-1966), author of 17 books and in his day second only to John Dewey in the breadth of his thinking, is now largely forgotten, and his once-influential writings are out of print. This volume, which combines a rich selection of Hocking’s work with incisive essays by distinguished scholars, seeks to recover Hocking’s valuable contributions to philosophical thought.
This paper discusses the predicament of Oscar Pistorius. He is a Paralympic gold medallist who wishes to participate in the Olympics in Beijing in 2008. Following a brief introductory section, the paper discusses the arguments that could be, and have been, deployed against his participation in the Olympics, should he make the qualifying time for his chosen event (400m). The next section discusses a more hypothetical argument based upon a specific understanding of the fair opportunity rule. According to this, (...) there may be a case for allowing Pistorius to compete even if he should fail to make the official qualifying time. The final part of the paper reviews the situation at the time of writing and offers some assessment of the strategy of the IAAF in responding to it. It is argued below that the proper focus for assessment of Pistorius's eligibility to compete should not be on whether his blades lead to his having an unfair advantage over his competitors, but instead should focus on whether what he does counts as running.

A review of Ernest Sosa’s book Apt Belief and Reflective Knowledge. While I think Sosa is quite right that knowledge lies on a spectrum, and that its higher but not its lower reaches require of knowers, when challenged, a strong degree of explanatory coherence (ability to understand and discursively defend the basis of their beliefs), I also point out problems with certain aspects of his account.
This paper offers and analysis of Ernest Sosa's Virtue Perspectivism. Although Sosa has been credited with fathering the influential contemporary movement known as Virtue Epistemology, I argue that Sosa imprudently abandons the reliabilist-based insights of Virtue Epistemology in favor of a reflection-based, "perspectival"' view. Sosa's mixed allegiance to reliabilist-based and reflection-based views of knowledge, in fact, leads to an unwelcome tension in his thought which can be relieved by recognizing that his reflection-based view is in fact an account of (...) the cognitive state of understanding, rather than an account of knowledge. Sosa makes matters difficult for himself because he expects too much, as it were, from the concept of knowledge, and in the process burdens his view with elements of reflection it does not require. To solve the problem, I suggest that Sosa needs to develop a two-tiered epistemology which recognizes that knowledge, on the one hand, and understanding, on the other, both have necessary and sufficient conditions unique to themselves.

It seems fairly straightforward to describe what should and should not count as a disability into two separate and opposing categories. In this paper we will challenge this assumption and critically reflect on the narrow relations between the concepts of 'talent' and 'disability'. We further relate such matters of terminology and classification to issues of justice in what is conceived of as disability sport. Do current systems of classification do justice to the performances of disabled athletes? Is the organisation of (...) a just and fair competition similar for abled as it is for disabled sport? Two cases (of Francesco Lentini and Oscar Pistorius) will be explored to further illustrate the complexities of these questions, in particular when related to notions of normality and extraordinary performances.

The “grand problem” of AI has always been to build artificial agents of human-level intelligence, capable of operating in environments of real-world complexity. OSCAR is a cognitive architecture for such agents, implemented in LISP. OSCAR is based on my extensive work in philosophy concerning both epistemology and rational decision making. This paper provides a detailed overview of OSCAR. The main conclusions are that such agents must be capablew of operating against a background of pervasive ignorance, because the (...) real world is too complex for them to know more than a small fraction of what is true. This is handled by giving the agent the power to reason defeasibily. The OSCAR system of defeasible reasoning is sketched. It is argued that if epistemic cognition must be defeasible, planning must also be done defeasibly, and the best way to do that is to reason defeasibly about plans. A sketch is given about how this might work. (shrink)
Oscar is going to be the first artificial person — at any rate, he is going to be the first artificial person to be built in Tucson's Philosophy Department. Oscar's creator, John Pollock, maintains that once Oscar is complete he will experience qualia, will be self-conscious, will have desires, fears, intentions, and a full range of mental states (Pollock 1989, pp. ix–x). In this paper I focus on what seems to me to be the most problematical of (...) these claims, viz., that Oscar will experience qualia. I argue that we have not been given sufficient reasons to believe this bold claim. I doubt that Oscar will enjoy qualitative conscious phenomena and I maintain that it will be like nothing to be Oscar. (shrink)
It is well known that Ernest Gellner made substantial use of his knowledge of the social sciences in philosophy. Here I discuss how he used it on the basis of a few examples taken from Gellner’s philosophical output. It is argued that he made a number of highly original “translations”, orre-interpretations, of philosophical theories and problems using his knowledge of the social sciences. While this method is endorsed, it is also argued that some of Gellner’s translations crossed the line (...) between the original and the idiosyncratic. (shrink)
The “grand problem” of AI has always been to build artificial agents with human-like intelligence. That is the stuff of science fiction, but it is also the ultimate aspiration of AI. In retrospect, we can understand what a difficult problem this is, so since its inception AI has focused more on small manageable problems, with the hope that progress there will have useful implications for the grand problem. Now there is a resurgence of interest in tackling the grand problem head-on. (...) Perhaps AI has made enough progress on the little problems that we can fruitfully address the big problem. The objective is to build agents of human-level intelligence capable of operating in environments of real-world complexity. I will refer to these as GIAs — “generally intelligent agents”. OSCAR is a cognitive architecture for GIAs, implemented in LISP.1 OSCAR draws heavily on my work in philosophy concerning both epistemology (Pollock 1974, 1986, 1990, 1995, 1998, 2008b, 2008; Pollock and Cruz 1999; Pollock and Oved, 2005) and rational decision making (2005, 2006, 2006a).

Ernest Gellner was a unique scholar whose work covered areas as diverse as social anthropology, analytical philosophy, the sociology of the Islamic world, nationalism, psychoanalysis, East European transformations and kinship structures. Despite this diversity, there is an exceptional degree of unity and coherence in Gellner's work with his distinctly modernist, rationalist and liberal world-view evident in everything he wrote. His central problematic remains constant: understanding how the modern world came into being and to what extent it is unique relative (...) to all other social forms. Ten years after his death, this book brings together leading social theorists to evaluate the significance of Gellner's legacy and to re-examine his central concerns. It corrects many misunderstandings and critically engages with Gellner's legacy to provide a cutting edge contribution to understanding our contemporary post-9/11, global, late modern, social condition.

In this paper, I analyze the significance of Ernest Nagel's introduction of the notion of model in his reconstruction of scientific theories. Nagel's account is generally considered as a version of the "received view" of theories, whose main advocate is Carnap. However, I will show that Nagel's considerations on models imply a renunciation to the logical empiricists' project of the formalization of scientific theories. I will argue that Nagel implicitly acknowledges that, in order to study the content of theories, (...) one cannot abstract away from the agents' understanding of theories, and from the reasoning processes they perform when using them.

When moral or religious teachings have public and political effects, analysis usually focuses on the message, but attention to the manner in which the teachings are communicated is equally important in understanding their power to influence the course of events. Oscar Romero's particular style of moral discourse was remarkably effective for three reasons: First, his moral reasoning resonated with Salvadoran identity. It was intelligible within those reigning assumptions about national history and territory that could actually move a public to (...) action. Second, his moral judgments were timely. Romero sought to discern what was possible for the Salvadoran public at a given moment. Third, Romero had integrity as a public figure. He lived in such a way that his life, and especially his death, became an exemplary embodiment of the larger religious narrative that both grounded his ethics and gave meaning to the nation. (shrink)

The definition of 'Englishness' has become the subject of considerable debate, and in this important contribution tto Ideas in Context Julia Stapleton looks at the work of one of the most wide-ranging and influential theorists of the English nation, Ernest Barker. The first holder of the Chair of Political Science at Cambridge, Barker wrote prolifically on the history of political thought and contemporary political theory, and his writings are notable for fusing three of the dominant strands of late-nineteenth and (...) early-twentieth century political thought, Whiggism, Idealism and Pluralism. Infused with a strong cultural sense of nationhood, Barker's writings influenced a broad non-academic audience, and their subsequent neglect graphically demonstrates the fate of a certain vision of Liberal England in the generation after World War One. With, however, the erosion of a particular sense of Englishness, Barker's ideas have begun to assume renewed resonance. (shrink)
OSCAR is a fully implemented architecture for a cognitive agent, based largely on the author’s work in philosophy concerning epistemology and practical cognition. The seminal idea is that a generally intelligent agent must be able to function in an environment in which it is ignorant of most matters of fact. The architecture incorporates a general-purpose defeasible reasoner, built on top of an efficient natural deduction reasoner for first-order logic. It is based upon a detailed theory about how the various (...) aspects of epistemic and practical cognition should interact, and many of the details are driven by theoretical results concerning defeasible reasoning. The architecture is easily extensible by changing the set of inference schemes supplied to the reasoner. Existing inference schemes handle many kinds of epistemic cognition, including reasoning from perceptual input, causal reasoning and the frame problem, and reasoning defeasibly about probabilities. Work is underway to implement a system of defeasible decisiontheoretic planning. (shrink)

Abstract I agree with Sosa that intuitions are best thought of as attractions to believe a certain proposition merely on the basis of understanding it. However, I don’t think it is constitutive of them that they supply strictly foundational justification for the propositions they justify, though I do believe that it is important that the intuition of a suitable subject be thought of as a prima facie justification for his intuitive judgment, independently of the reliability of his underlying capacities. I (...) also think that we need to be able to explain how mere understanding of a proposition can confer upon us an ability to have reliable intuitions, that we cannot simply take that idea for granted. And that when try to explain that, our best avenue for doing so is to take the intuitions as constituting the understanding of which they are said to be a manifestation. (shrink)
Foundationalism is false; after all, foundational beliefs are arbitrary, they do not solve the epistemic regress problem, and they cannot exist withoutother (justified) beliefs. Or so some people say. In this essay, we assess some arguments based on such claims, arguments suggested in recent work by Peter Klein and Ernest Sosa.
Concentrating on the music, politics, and philosophy of Richard Wagner, Lydia Goehr addresses some fundamental questions of German Romanticism: Is all music musical? Is music made less musical by the presence of words? What is musical autonomy? How do composers avoid censorship? How are composers affected by exile? Can music articulate a 'politics for the future'? What is the relation between music and philosophy?
Stuart Russell [14] describes rational agents as --œthose that do the right thing--�. The problem of designing a rational agent then becomes the problem of figuring out what the right thing is. There are two approaches to the latter problem, depending upon the kind of agent we want to build. On the one hand, anthropomorphic agents are those that can help human beings rather directly in their intellectual endeavors. These endeavors consist of decision making and data processing. An agent that (...) can help humans in these enterprises must make decisions and draw conclusions that are rational by human standards of rationality. Anthropomorphic agents can be contrasted with goal-oriented agents --” those that can carry out certain narrowly-defined tasks in the world. Here the objective is to get the job done, and it makes little difference how the agent achieves its design goal. (shrink)
