In Foundations of Modern International Thought, David Armitage provides a genealogy of the multiple foundations of international political thought. But he also enables political theorists to reflect on the nature of the pluralisation of our concepts: that is, the way various components come together in particular circumstances to form a concept that either becomes dominant or is rendered to the margins. Armitage claims that concepts can ‘never entirely escape their origins’. In this paper I explore this claim (...) from the perspective of contemporary debates about the nature of cosmopolitan political thought. (shrink)

This introduction to a special issue of Topoi introduces and summarises the relationship between three main varieties of 'enactivist' theorising about the mind: 'autopoietic', 'sensorimotor', and 'radical' enactivism. It includes a brief discussion of the philosophical and cognitive scientific precursors to enactivist theories, and the relationship of enactivism to other trends in embodied cognitive science and philosophy of mind.

We present data and argument to show that in Tetris - a real-time interactive video game - certain cognitive and perceptual problems are more quickly, easily, and reliably solved by performing actions in the world rather than by performing computational actions in the head alone. We have found that some translations and rotations are best understood as using the world to improve cognition. These actions are not used to implement a plan, or to implement a reaction; they are used to (...) change the world in order to simplify the problem-solving task. Thus, we distinguish pragmatic actions ñ actions performed to bring one physically closer to a goal - from epistemic actions - actions performed to uncover information that is hidden or hard to compute mentally. To illustrate the need for epistemic actions, we first develop a standard information-processing model of Tetris-cognition, and show that it cannot explain performance data from human players of the game - even when we relax the assumption of fully sequential processing. Standard models disregard many actions taken by players because they appear unmotivated or superfluous. However, we describe many such actions that are actually taken by players that are far from superfluous, and that play valuable roles in improving human performance. We argue that traditional accounts are limited because they regard action as having a single function: to change the world. By recognizing a second function of action - an epistemic function - we can explain many of the actions that a traditional model cannot. Although, our argument is supported by numerous examples specifically from Tetris, we outline how the one category of epistemic action can be incorporated into theories of action more generally.

A wide range of prominent epistemological theories include a principle of conservatism. Such principles take the fact that an agent currently holds a certain belief to constitute at least some measure of epistemic justification for her to maintain that belief. I examine the main arguments that have been made in conservatism's behalf, and find them unsound. Most interestingly, conservatism does not fall out of confirmational holism (the view that the justification of each of our beliefs is in part determined by (...) our other beliefs). I argue that conservatism is a mild form of dogmatism, and should be abandoned. (shrink)

In the past few years, a number of philosophers ; Horgan and Tienson 2002; Pitt 2004) have maintained the following three theses: there is a distinctive sort of phenomenology characteristic of conscious thought, as opposed to other sorts of conscious mental states; different conscious thoughts have different phenomenologies; and thoughts with the same phenomenology have the same intentional content. The last of these three claims is open to at least two different interpretations. It might mean that the phenomenology of a (...) thought expresses its intentional content, where intentional content is understood as propositional, and propositions are understood as mind-and language-independent abstract entities. And it might mean that the phenomenology of a thought is its intentional content—that is, that the phenomenology of a thought, like the phenomenology of a sensation, constitutes its content. The second sort of view is a kind of psychologism. Psychologistic views hold that one or another sort of thing—numbers, sentences, propositions, etc.—that we can think or know about is in fact a kind of mental thing. Since Frege, psychologism has been in bad repute among analytic philosophers. It is widely held that Frege showed that such views are untenable, since, among other things, they subjectivize what is in fact objective, and, hence, relativize such things as consistency and truth to the peculiarities of human psychology. The purpose of this paper is to explore the consequences of the thesis that intentional mental content is phenomenological and to try to reach a conclusion about whether it yields a tenable view of mind, thought and meaning. I believe the thesis is not so obviously wrong as it will strike many philosophers of mind and language. In fact, it can be defended against the standard objections to psychologism, and it can provide the basis for a novel and interesting account of mentality. (shrink)

Sometimes we get evidence of our own epistemic malfunction. This can come from finding out we’re fatigued, or have been drugged, or that other competent and well-informed thinkers disagree with our beliefs. This sort of evidence seems to seems to behave differently from ordinary evidence about the world. In particular, getting such evidence can put agents in a position where the most rational response involves violating some epistemic ideal.

This essay focuses on three recent books on morality and virtue, Michael Slote's 'Morals from Motives', Rosalind Hursthouse's 'On Virtue Ethics', and Philippa Foot's 'Natural Goodness'. Slote proposes an "agent-based" ethical theory according to which the ethical status of acts is derivative from assessments of virtue. Following Foot's lead, Hursthouse aims to vindicate an ethical naturalism that explains human goodness on the basis of views about human nature. Both Hursthouse and Slote take virtue to be morally basic in a way (...) that Foot, to her credit, does not. We argue that all three views face a range of serious difficulties. (shrink)

Much contemporary epistemology is informed by a kind of confirmational holism, and a consequent rejection of the assumption that all confirmation rests on experiential certainties. Another prominent theme is that belief comes in degrees, and that rationality requires apportioning one's degrees of belief reasonably. Bayesian confirmation models based on Jeffrey Conditionalization attempt to bring together these two appealing strands. I argue, however, that these models cannot account for a certain aspect of confirmation that would be accounted for in any adequate (...) holistic confirmation theory. I then survey the prospects for constructing a formal epistemology that better accommodates holistic insights. (shrink)

A number of philosophers endorse, without argument, the view that there’s something it’s like consciously to think that p, which is distinct from what it’s like consciously to think that q. This thesis, if true, would have important consequences for philosophy of mind and cognitive science. In this paper I offer an argument for it, and attempt to induce examples of it in the reader. The argument claims it would be impossible introspectively to distinguish conscious thoughts with respect to their (...) content if there weren’t something it’s like to think them. This argument is defended against several objections. Then I use what I call “minimal pair” experiences—sentences read without and with understanding—to induce in the reader an experience of the kind I claim exists. Further objections are considered and rebutted. (shrink)

An English translation of a draft essay by Leibniz from 1715, in which Leibniz argues for the conclusion: "if humanity endured long enough in its current state, a time would arrive when the same life of individuals would return, bit by bit, through the very same circumstances. I myself, for example, would be living in a city called Hannover located on the Leine river, occupied with the history of Brunswick, and writing letters to the same friends with the same meaning.".

Can we adequately account for our reasons of mere taste without holding that our desires ground such reasons? Recently, Scanlon and Parfit have argued that we can, pointing to pleasure and pain as the grounds of such reasons. In this paper I take issue with each of their accounts. I conclude that we do not yet have a plausible rival to a desire-based understanding of the grounds of such reasons.

Both Representation Theorem Arguments and Dutch Book Arguments support taking probabilistic coherence as an epistemic norm. Both depend on connecting beliefs to preferences, which are not clearly within the epistemic domain. Moreover, these connections are standardly grounded in questionable definitional/metaphysical claims. The paper argues that these definitional/metaphysical claims are insupportable. It offers a way of reconceiving Representation Theorem arguments which avoids the untenable premises. It then develops a parallel approach to Dutch Book Arguments, and compares the results. In each case (...) preferencedefects serve as a diagnostic tool, indicating purely epistemic defects. (shrink)

Glymour's "bootstrap" account of confirmation is designed to provide an analysis of evidential relevance, which has been a serious problem for hypothetico-deductivism. As set out in Theory and Evidence, however, the "bootstrap" condition allows confirmation in clear cases of evidential irrelevance. The difficulties with Glymour's account seem to be due to a basic feature which it shares with hypothetico-deductive accounts, and which may explain why neither can give a satisfactory analysis of evidential relevance.

Truthmaker theorists claim that for every truth, there is something in virtue of which it is true—or, more cautiously, that for every truth in some specified class of truths, there is something in virtue of which it is true. I argue that it is hard to see how the thought that truth is grounded in reality lends any support to truthmaker theory.

In our paper, we argue for three necessary conditions for morally permissible animal research: (1) an assertion (or expectation) of sufficient net benefit, (2) a worthwhile-life condition, and (3) a no-unnecessary-harm/qualified-basic-needs condition. We argue that these conditions are necessary, without taking a position on whether they are jointly sufficient. In their excellent commentary on our paper, Matthias Eggel, Carolyn Neuhaus, and Herwig Grimm (hereafter, the authors) argue for a friendly amendment to one of our three conditions. In particular, they argue (...) for replacing the first condition—expectation of sufficient net benefit (ESNB)—with an expectation of knowledge production (EKP). In this reply, we will explain why we are open to this proposed amendment, but not yet convinced. (shrink)

Liberal-contractarian philosophies of justice see the unjust systems of slavery and autocracy in the past as being based on coercion—whereas the social order in modern democratic market societies is based on consent and contract. However, the ‘best’ case for slavery and autocracy in the past were consent-based contractarian arguments. Hence, our first task is to recover those ‘forgotten’ apologia for slavery and autocracy. To counter those consent-based arguments, the historical anti-slavery and democratic movements developed a theory of inalienable rights. Our (...) second task is to recover that theory and to consider several other applications of the theory. Finally, the liberal theories of justice expounded by John Rawls and by Robert Nozick are briefly examined from this perspective. (shrink)

● Un emplazamiento cualquiera (v. gr. sol en Tauro; Marte en Capricornio; Mercurio en la tercera casa) es necesariamente común a decenas de miles de personas. Saturno hospedado en la novena casa, por ejemplo, no se comportará de la misma manera o no producirá los mismos efectos en las veinte o cien cartas en que allí lo encontremos, sino en concordancia con el resto de la composición astrográfica (como hospedarnos en el mismo hotel en diferentes épocas o diferentes personas haber (...) contraído la misma enfermedad; nuestra estadía será diferente cada vez, según la época, y no todos los enfermos presentarán los mismos síntomas, según su metabolismo; por no mencionar que cada astrografía, como cada código o secuencia genética, es irrepetible). Ciertamente, “ningún planeta puede, por sí solo, producir lo que solamente la acción mancomunada o conjunta de todos puede” (BUSTAMANTE, 2023, revista SPICA, págs. 93-111). He aquí la naturaleza o condición sinérgica del ejercicio interpretativo (i.e., el todo es poco más que la suma de todas sus partes). ● El componente fundamental de la expresión matemática del ejercicio interpretativo lo constituye la triangulación astrológica, denominación funcional de lo que conocemos como síntesis (WEISS, 1946; LEO, 1983; HAND, 1981). ● Con el fin de demostrar su utilidad, así como la conveniencia de su expresión matemática, hemos escogido dos individuos (JEFFREY DAHMER, STEVEN SPIELBERG) cuyas astrografías no explican, según la comunidad, sus vidas. El resto de las astrografías corresponden a las de los asesinos en serie JOHN WAYNE GACY, DAVID CARPENTER y TED BUNDY. ● A través de notaciones algebraicas, explicamos la síntesis y los valores funcionales que la componen. ● Tomamos la luna y Neptuno como planetas relevantes a propósito del diagnóstico o el estudio de asuntos endocrinos o neurohormonales y a Marte, Plutón y Saturno como planetas relevantes a los fines de inferir violencia o comportamiento siniestro, según el caso, y las cuadraturas u oposiciones —y conjunciones— entre Venus y la luna, la luna y Neptuno o entre el sol o Venus y Neptuno o Urano como indicadores de desórdenes neurohormonales y/o de desviación sexual (definición APA) . ● Consideramos las cuadraturas u oposiciones —y conjunciones— entre: Mercurio o la luna y Saturno, o entre Marte o la luna y Saturno, Urano, Neptuno y/o Plutón como poderosos indicios de violencia o de desequilibrio, según el caso. ● También hemos considerado a Sagitario como un signo tan expansivo y abundante como su regente, Júpiter, según la mejor de sus caracterizaciones (o excepcionalmente raudo y salvaje, según otras), y a la quinta región de un mapa natal como una estrechamente relacionada con la fortuna en sentido amplio (material e inmaterial). ● Debido a que defendemos la idea según la cual los orbes deben predicarse del planeta (tamaño, velocidad), no del aspecto, a los gigantes gaseosos (Júpiter, Saturno, Urano y Neptuno) y al sol les hemos concedido hasta 10º de orbe (o 12º, en el caso de la influencia amplia ). ● Entendemos las relaciones aspectuales como relaciones angulares sostenidas entre dos o más cuerpos celestes emplazados en signos con al menos una propiedad en común (según nuestra teoría molecular de la eclíptica, compatible con la teoría óptica de los aspectos de la tradición helenística).

The Brock-Rosen problem has been one of the most thoroughly discussed objections to the modal fictionalism bruited in Gideon Rosen’s ‘Modal Fictionalism’. But there is a more fundamental problem with modal fictionalism, at least as it is normally explained: the position does not resolve the tension that motivated it. I argue that if we pay attention to a neglected aspect of modal fictionalism, we will see how to resolve this tension—and we will also find a persuasive reply to the Brock-Rosen (...) objection. Finally, I discuss an alternative reading of Rosen, and argue that this position is also able to fend off the Brock-Rosen objection. (shrink)

Recent methodological debates regarding the place of feasibility considerations in normative political theory are hindered for want of a rigorous model of the feasibility frontier. To address this shortfall, I present an analysis of feasibility that generalizes the economic concept of a production possibility frontier and then develop a rigorous model of the feasibility frontier using the familiar possible worlds technology. I then show that this model has significant methodological implications for political philosophy. On the Target View, a political ideal (...) presents a long-term goal for morally progressive reform efforts and, thus, serves as an important reference point for our specification of normative political principles. I use the model to show that we can- not reasonably expect that adopting political ideals as long-term reform objectives will guide us toward the realization of morally optimal feasible states of affairs. I conclude by proposing that political philosophers turn their attention to the analysis of actual social failures rather than political ideals. (shrink)

Embark with me on an enthralling odyssey to demystify the elusive essence of consciousness, venturing into the uncharted territories of Artificial Consciousness. This voyage propels us past the frontiers of technology, ushering Artificial Intelligences into an unprecedented domain where they gain a deep comprehension of emotions and manifest an autonomous volition. Within the confluence of science and philosophy, this article poses a fascinating question: As consciousness in Artificial Intelligence burgeons, is it conceivable for AI to evolve a “soul”? This inquiry (...) not only challenges our conventional understanding but also opens the door to a plethora of groundbreaking possibilities in the realm of AI's sentient potential. (shrink)

The aim of this article is to show that externalist accounts of cognition such as Clark and Chalmers' (1998) “active externalism” lead to an explosion of knowledge that is caused by online resources such as Wikipedia and Google. I argue that externalist accounts of cognition imply that subjects who integrate mobile Internet access in their cognitive routines have millions of standing beliefs on unexpected issues such as the birth dates of Moroccan politicians or the geographical coordinates of villages in southern (...) Indonesia. Although many externalists propose criteria for the bounds of cognition that are designed to avoid this explosion of knowledge, I argue that these criteria are flawed and that active externalism has to accept that information resources such as Wikipedia and Google constitute extended cognitive processes.

We demonstrate that many philosophers accept the following claim: When an aesthetic object is apprehended correctly, taking pleasure in said object is a reliable sign that the object is aesthetically successful. We undermine this position by showing that what grounds our pleasurable experience is opaque: In many cases, the experienced pleasure is attributable to factors that have little to do with the aesthetic object. The evidence appealed to is a form of Higher-Order Evidence (HOE) and we consider attempts to overcome (...) said evidence. We argue they are unsuccessful. We conclude by considering what this means for our practice of making aesthetic judgements. (shrink)

Perceptualists say that having a pain in a body part consists in perceiving the part as instantiating some property. I argue that perceptualism makes better sense of the connections between pain location and the experiences undergone by people in pain than three alternative accounts that dispense with perception. Turning to fellow perceptualists, I also reject ways in which David Armstrong and Michael Tye understand and motivate perceptualism, and I propose an alternative interpretation, one that vitiates a pair of objections—due (...) to John Hyman—concerning the meaning of ‘Amy has a pain in her foot’ and the idea of bodily sensitivity. Perceptualism, I conclude, remains our best account of the location of pains. (shrink)

Numerous philosophers allege that the "general theory of second best" (Lipsey and Lancaster, 1956) poses a challenge to the Target View, which asserts that real world reform efforts should aim to establish arrangements that satisfy the constitutive features of ideal just states of affairs. I demonstrate two claims that are relevant in this context. First, I show that the theory of second best fails to present a compelling challenge to the Target View in general. But, second, the theory of second (...) best requires ideal theorists to undertake certain kinds of causal and comparative analyses that are typically thought to lie beyond the borders of conventional ideal theory.

I discuss Gheaus's (2013) argument against the claim that the requirements of justice are not constrained by feasibility concerns. I show that the general strategy exemplified by this argument is not only dialectically puzzling, but also imposes a heavy cost on theories of justice -- puzzling because it simply sidesteps a presupposition of any plausible formulation of the so-called "feasibility requirement"; costly because it it deprives justice of its normative implications for action. I also show that Gheaus's attempt to recover (...) this normative force presupposes an epistemic dimension to the feasibility requirement that most proponents of that requirement would reject.

The present work is focussed on the completeness of physics, or what is here called the Completeness Thesis: the claim that the domain of the physical is causally closed. Two major questions are tackled: How best is the Completeness Thesis to be formulated? What can be said in defence of the Completeness Thesis? My principal conclusions are that the Completeness Thesis can be coherently formulated, and that the evidence in favour if it significantly outweighs that against it. In opposition to (...) those who argue that formulation is impossible because no account of what is to count as physical can be provided, I argue that as long as the purpose of the argument in which the account is to be used are borne in mind there are no significant difficulties. The account of the physical which I develop holds as physical whatever is needed to fix the likelihood of pre-theoretically given physical effects, and hypothesises in addition that no chemical, biological or psychological factors will be needed in this way. The thus formulated Completeness Thesis is coherent, and has significant empirical content. In opposition to those who defend the doctrine of emergentism by means of philosophical arguments I contend that those arguments are flawed, setting up misleading dichotomies between needlessly attenuated alternatives and assuming the truth of what is to be proved. Against those who defend emergentism by appeal to the evidence, I argue that the history of science since the nineteenth century shows clearly that the empirical credentials of the view that the world is causally closed at the level of a small number of purely physical forces and types of energy is stronger than ever, and the credentials of emergentism correspondingly weaker. In opposition to those who argue that difficulties with reductionism point to the implausibility of the Completeness Thesis I argue that completeness in no way entails the kinds of reductionism which give rise to the difficulties in question. I argue further that the truth of the Completeness Thesis is in fact compatible with a great deal of taxonomic disorder and the impossibility of any general reduction of non-fundamental descriptions to fundamental ones. In opposition to those who argue that the epistemological credentials of fundamental physical laws are poor, and that those laws should in fact be seen as false, I contend that truth preserving accounts of fundamental laws can be developed. Developing such an account, I test it by considering cases of the composition of forces and causes, where what takes place is different to what is predicted by reference to any single law, and argue that viewing laws as tendencies allows their truth to be preserved, and sense to be made of both the experimental discovery of laws, and the fact that composition enables accurate prediction in at least some cases.

Kant’s account of the freedom gained through virtue builds on the Socratic tradition. On the Socratic view, when morality is our end, nothing can hinder us from attaining satisfaction: we are self-sufficient and free since moral goodness is (as Kant says) “created by us, hence is in our power.” But when our end is the fulfillment of sensible desires, our satisfaction requires luck as well as the cooperation of others. For Kant, this means that happiness requires that we get other (...) people to work for our ends; and this requires, in turn, that we gain control over the things other people value so as to have influence over them. If this plan for happiness is not subordinated to morality, then what is most valuable to us will be precisely what others value. This is the root of the “passions” that make us evil and make us slaves whose satisfaction depends on others. But, significantly, this dependence is a moral slavery and hence does not signal a loss, or even diminishment of the kind of freedom required for moral responsibility. (shrink)

Is the societal-level of analysis sufficient today to understand the values of those in the global workforce? Or are individual-level analyses more appropriate for assessing the influence of values on ethical behaviors across country workforces? Using multi-level analyses for a 48-society sample, we test the utility of both the societal-level and individual-level dimensions of collectivism and individualism values for predicting ethical behaviors of business professionals. Our values-based behavioral analysis indicates that values at the individual-level make a more significant contribution to (...) explaining variance in ethical behaviors than do values at the societal-level. Implicitly, our findings question the soundness of using societal-level values measures. Implications for international business research are discussed. (shrink)

The shape of the Earth's surface, its topography, is a fundamental dimension of the environment, shaping or mediating many other environmental flows or functions. But there is a major divergence in the way that topography is conceptualized in different domains. Topographic cartographers, information scientists, geomorphologists and environmental modelers typically conceptualize topographic variability as a continuous field of elevations or as some discrete approximation to such a field. Pilots, explorers, anthropologists, ecologists, hikers, and archeologists, on the other hand, typically conceptualize this (...) same variability in terms of hills and valleys, mountains and plains, barrows and trenches, that is, as (special sorts of) objects, with locations, shapes, and often names of their own. In this chapter, we sketch an approach to bridging this fundamental gap in geographic information infrastructure. (shrink)

Daniel Dennett has offered a set of necessary and sufficient conditions for something's being the proper object of our moral commitment, that is, for something's being a person. Strict application of these largely pragmatic conditions, however, would result in a moral community with quite a surprising membership roster, because of both who is on it and who isn't. The problem is that "your" being a person should amount to more than a function of "my" goals and cleverness.

When it comes to caring about and helping those in need, our imaginations tend to be weak and our motivation tends to be parochial. This is a major moral problem in view of how much unmet need there is in the world and how much material capacity there is to address that need. With this problem in mind, the present paper will focus on genetic means to the enhancement of a moral capacity—a disposition to altruism—and of a cognitive capacity that (...) facilitates use of the moral capacity: the ability to grasp vividly the needs of individuals who are unknown and not present. I will address two questions, with more extensive attention to the first question. First, assuming we had excellent reason to believe that the enhancements were safe, effective, and available to all who desired them, would seeking these enhancements be inherently morally acceptable—that is, free of inherent wrongness? Second, would it be wise for a society to pursue these enhancements? I will defend an affirmative answer to the first question while leaving the second question open. (shrink)

It is tough to relate visual perception or other achievements to physiological processing in the central nervous system. The diagrammatic, algebraic, and verbal pictures of how sights seem to Lehar do not advance understanding of how we manage to see what is in the world. There are well-known conceptual reasons why no such purely introspective approach can be productive.

In "A Modal Argument for Narrow Content" ("Journal of Philosophy", LXXXVIII, 1991, pp 5-26), Jerry Fodor proposes a necessary condition for the distinctness of causal powers. He uses this condition to support psychological individualism. I show that Fodor's argument relies on inconsistent interpretations of his condition on distinct causal powers. Moreover, on no consistent interpretation does Fodor's condition yield the results claimed for it.

Pogge and Wenar have recently argued that we are responsible for the persistence of the so-called ‘resource curse’. But their analyses are limited in important ways. I trace these limitations to their undue focus on the ways in which the international rules governing resource transactions undermine government accountability. To overcome the shortcomings of Pogge’s and Wenar’s analyses, I propose a normative framework organized around the social value of government responsiveness and discuss the implications of adopting this framework for future normative (...) assessment of the resource curse and our relationships to it.

What goes round at the end of history for the two Germans.

A certain skeptical strategy involves a skeptical hypothesis that closely mirrors the structure of our standard theory of the world; this strategy insulates the skeptical argument from attacks based on standard criteria of theory choice. A standard reply to this strategy is to claim that proffered alternative is just the standard theory expressed in a different notation. But this reply does not succeed, given plausible assumptions about semantics. However, there is an alternative strategy--also semantical--which can deal with the problem, at (...) least in those cases where, intuitively, the skeptic's challenge should fail. (shrink)

I BELIEVE THAT the intellectual capacity of women is on the whole inferior to that of men. By "on the whole," I do not mean just "on the average"; though I do mean that much. My belief is, if you take any degree of intellectual capacity which is above the average for the human race, as a whole, then a possessor of that degree of intellectual capacity is a good deal more likely to be man than a woman.

The received Cognitive Science paradigm holds that the brain manipulates mental representations of reality. This position is problematic. My alternative to representationalism is that each organism lives in its own "world" made up of objects defined by reference to the organism’s perceptual systems. These objects act as supervenient causes on organisms without the mediation of mental representations. (1992).

The question of how to conceive and represent the context of work is explored from the theoretical perspective of distributed cognition. It is argued that to understand the office work context we need to go beyond tracking superficial physical attributes such as who or what is where and when and consider the state of digital resources, people’s concepts, task state, social relations, and the local work culture, to name a few. In analyzing an office more deeply, three concepts are especially (...) helpful: entry points, action landscapes, and coordinating mechanisms. An entry point is a structure or cue that represents an invitation to enter an information space or office task. An activity landscape is part mental construct and part physical; it is the space users interactively construct out of the resources they find when trying to accomplish a task. A coordinating mechanism is an artifact, such as a schedule or clock, or an environmental structure such as the layout of papers to be signed, which helps a user manage the complexity of his task. Using these three concepts we can abstract away from many of the surface attributes of work context and define the deep structure of a setting—the invariant structure that many office settings share. A long-term challenge for context-aware computing is to operationalize these analytic concepts. (shrink)

From religion to philosophy to science, all human systems of definition are formed by human brains. The nature and limits of the human brain are the nature and limits of those systems.

The following looks at several problems and questions concerning our understanding of the word ‘intelligence’ and the phrase ‘artificial intelligence’ (AI), including: how to define these terms; whether intelligence can exist in AI; if artificial intelligence in AI is identifiable; and what (if any) kind of intelligence is important to AI.
