A proposal for an objective interpretation of probability is introduced and discussed: probabilities as deriving from ranges in suitably structured initial-state spaces. Roughly, the probability of an event on a chance trial is the proportion of initial states that lead to the event in question within the space of all possible initial states associated with this type of experiment, provided that the proportion is approximately the same in any not too small subregion of the space. This I would like to (...) call the “natural-range conception” of probability. Providing a substantial alternative to frequency or propensity accounts of probability in a deterministic setting, it is closely related to the so-called “method of arbitrary functions”. It is explicated, confronted with certain problems, and some ideas how these might be overcome are sketched and discussed. (shrink)

Jerry Fodor and Ernest Lepore [(1992) Holism: a shopper's guide, Oxford: Blackwell; (1996) in R. McCauley (Ed.) The Churchlands and their critics , Cambridge: Blackwell] have launched a powerful attack against Paul Churchland's connectionist theory of semantics--also known as state space semantics. In one part of their attack, Fodor and Lepore argue that the architectural and functional idiosyncrasies of connectionist networks preclude us from articulating a notion of conceptual similarity applicable to state space semantics. Aarre Laakso and Gary Cottrell [(1998) (...) in M. A. Gernsbacher & S. Derry (Eds) Proceedings of the 20th Annual Conference of the Cognitive Science Society, Mahway, NJ: Erlbaum; Philosophical Psychology ] 13, 47-76 have recently run a number of simulations on simple feedforward networks and applied a mathematical technique for measuring conceptual similarity in the representational spaces of those networks. Laakso and Cottrell contend that their results decisively refute Fodor and Lepore's criticisms. Paul Churchland [(1998) Journal of Philosophy, 95, 5-32 ] goes further. He uses Laakso and Cottrell's neurosimulations to argue that connectionism does furnish us with all we need to construct a robust theory of semantics and a robust theory of translation. In this paper I shall argue that whereas Laakso and Cottrell's neurocomputational results may provide us with a rebuttal of Fodor and Lepore's argument, Churchland's conclusion is far too optimistic. In particular, I shall try to show that connectionist modelling does not provide any objective criterion for achieving a one-to-one accurate translational mapping across networks. (shrink)

This paper aims to increase the reader’s understanding of how the notion of the ‘bobby on the beat’ has been elevated to iconic, if not mythical, status within British policing. In doing so, the article utilises the semiotic idea of myth, as conceptualized by Roland Barthes, to explore how through representations of the ‘bobby on the beat’ police officers have been projected in a more avuncular re-assuring role to a public fearful of crime, which fails to do service to the (...) signifying practices that accompany and embody the visible police patrol. Indeed, police patrol work secures social space for the State and although it does re-assure anxious members of society that their social world is safe and secure, for others, it further illustrates how their social space is fragile and troubled. On another level, the ‘bobby’ narrative has also been harnessed as part of a broader mythologizing of ‘Englishness’ and quintessential British characteristics. (shrink)

Questions concerning the epistemological status of computer science are, in this paper, answered from the point of view of the formal verification framework. State space reduction techniques adopted to simplify computational models in model checking are analysed in terms of Aristotelian abstractions and Galilean idealizations characterizing the inquiry of empirical systems. Methodological considerations drawn here are employed to argue in favour of the scientific understanding of computer science as a discipline. Specifically, reduced models gained by Dataion are acknowledged as Aristotelian (...) abstractions that include only data which are sufficient to examine the interested executions. The present study highlights how the need to maximize incompatible properties is at the basis of both Abstraction Refinement, the process of generating a cascade of computational models to achieve a balance between simplicity and informativeness, and the Multiple Model Idealization approach in biology. Finally, fairness constraints, imposed to computational models to allow fair behaviours only, are defined as ceteris paribus conditions under which temporal formulas, formalizing software requirements, acquire the status of law-like statements about the software systems executions.

The literature on speculative bubbles in foreign exchange rates is voluminous, with much of it failing to reject the presence of bubbles in many exchange markets.1 Serious testing of this issue began with the work of Meese (1986), Evans (1986), and Woo (1987). Each used a different approach, and each found evidence failing to reject the presence of bubbles in at least some exchange markets.

The intersemiotic space: Adrianopol in F. Dostoevsky's "Crime and punishment" St. Petersburg. The article focuses on the peculiarities of the intertextual space of culture and the means of its analysis. Level analysis, compositional analysis and chronotopical analysis are juxtaposed in the paper. Textual and intertextual chronotopical analyses are considered separately. Two aspects of textual processuality are juxtaposed: the history of text production and the role of the manuscript page structure as a reflection of the writer's style and mode of thinking (...) (especially in the interserniotic relationship between picture, drawing andword); the history of text reception, its intersemiotic translation into different sign systems and its existence in culture in a scattered state. In this connection the notions of the individual and mental text are juxtaposed. As an example a page of F.Dostoevsky's notebook is taken, where an intricate combination of picture, calligraphy and text offers an interesting infonnation on the methods of formation of text conception.

It has often been suggested that the meaning of terms is theory dependent. Bas van Fraassen has proposed a particular way of inferring which sentences are true in virtue of meaning, given a theory in so-called state-space format. I examine his claims by means of simple examples.

This paper examines some of the methods animals and humans have of adapting their environment. Because there are limits on how many different tasks a creature can be designed to do well in, creatures with the capacity to redesign their environments have an adaptive advantage over those who can only passively adapt to existing environmental structures. To clarify environmental redesign I rely on the formal notion of a task environment as a directed graph where the nodes are states and (...) the links are actions. One natural form of redesign is to change the topology of this graph structure so as to increase the likelihood of task success or to reduce its expected cost, measured in physical terms. This may be done by eliminating initial states hence eliminating choice points; by changing the action repertoire; by changing the consequence function; and lastly, by adding choice points. Another major method for adapting the environment is to change its cognitive congeniality. Such changes leave the state space formally intact but reduce the number and cost of mental operations needed for task success; they reliably increase the speed, accuracy or robustness of performance. The last section of the paper describes several of these epistemic or complementary actions found in human performance. (shrink)

This paper addresses weighting and partitioning in complex reinforcement learning tasks, with the aim of facilitating learning. The paper presents some ideas regarding weighting of multiple agents and extends them into partitioning an input/state space into multiple regions with di erential weighting in these regions, to exploit di erential characteristics of regions and di erential characteristics of agents to reduce the learning complexity of agents (and their function approximators) and thus to facilitate the learning overall. It analyzes, in reinforcement learning (...) tasks, di erent ways of partitioning a task and using agents selectively based on partitioning. Based on the analysis, some heuristic methods are described and experimentally tested. We nd that some o -line heuristic methods performed the best, signi cantly better than single-agent models.

If you seem to be able to do data assimilation with uncertain static parameters then you are probably not working in environmental science. In this field, applications are often characterized by sensitive dependence on initial conditions and attracting sets in the state-space, which, taken together, can be a major challenge to numerical methods, leading to very peaky likelihood functions. Inherently stochastic models and uncertain static parameters increase the challenge.

Over the last century, psychoanalysis has transformed the ways in which we think about our relationships with others. Psychoanalytic concepts and methods, such as the unconscious and dream analysis, have greatly impacted on social, cultural and political theory. Reinterpreting the ways in which geography has explored people's mental maps and their deepest feelings about places, The Body and the City outlines a new cartography of the subject. Mapping key coordinates of meaning, identity and power across the sites of body (...) and city, author Steve Pile explores a wide range of critical thinking, particularly the work of Lefebvre, Freud and Lacan to present a pathbreaking psychoanalysis of space.

According to representionalists, qualia-the introspectible properties of sensory experience-are exhausted by the representational contents of experience. Representationalists typically advocate an informational psychosemantics whereby a brain state represents one of its causal antecedents in evolutionarily determined optimal circumstances. I argue that such a psychosemantics may not apply to certain aspects of our experience, namely, our experience of space in vision, hearing, and touch. I offer that these cases can be handled by supplementing informational psychosemantics with a procedural psychosemantics whereby a representation (...) is about its effects instead of its causes. I discuss conceptual and empirical points that favor a procedural representationalism for our experience of space. (shrink)

Newell and Simon’s seminal Human Problem Solving (1972) characterized a problem in terms of a goal state, a starting state, and a set of transition rules which define legitimate transitions from one state to another.1 Problem solving thus becomes a process of searching through a set of alternative states (the "problem space") in an effort to find a path leading from starting state to the goal state. The search process can be guided by heuristic principles which function to reduce the (...) problem space by judging some alternatives to be more worthy of exploration than others. This characterization of a problem and the problem solving process fits well the nature of deductive proof construction. Premise(s) and conclusion play the role of starting state and goal state, and valid rules of transformation serve as rules of legitimate transition among states. In fact, Human Problem Solving empirically investigated three particular problem solving tasks, and one of these is proof construction.... in sentential logic using an inferencereplacement rule set. This empirical research identifies several strategies which facilitate problem solving, such as means-ends reasoning, difference reduction, and working backwards from goal toward starting state. As detailed below, these methods have obvious applications to proof construction as taught in logic textbooks. Newell and Simon’s aim was to explain and predict the actual behavior of problem solvers. Beyond this, however, their empirical findings have normative consequences for how problem solvers should behave if they want to be successful. Moreover, these findings can have normative pedagogical consequences for the teaching of proof construction. (shrink)

One can (for the most part) formulate a model of a classical system in either the Lagrangian or the Hamiltonian framework. Though it is often thought that those two formulations are equivalent in all important ways, this is not true: the underlying geometrical structures one uses to formulate each theory are not isomorphic. This raises the question of whether one of the two is a more natural framework for the representation of classical systems. In the event, the answer is yes: (...) I state and sketch proofs of two technical results—inspired by simple physical arguments about the generic properties of classical systems—to the effect that, in a precise sense, classical systems evince exactly the geometric structure Lagrangian mechanics provides for the representation of systems, and none provided by Hamiltonian. The argument not only clarifies the conceptual structure of the two systems of mechanics, but also their relations to each other and their respective mechanisms for representing physical systems. It also shows why naïvely structural approaches to the representational content of physical theories cannot work. [Lagrange] grasped that he had gained a method of stating dynamical truths in a way, which is perfectly indifferent to the particular methods of measurement employed in fixing the positions of the various parts of the system. Accordingly, he went on to deduce equations of motion, which are equally applicable whatever quantitative measurements have been made, provided that they are adequate to fix positions. The beauty and almost divine simplicity of these equations is such that these formulae are worthy to rank with those mysterious symbols which in ancient times were held directly to indicate the Supreme Reason at the base of all things.

In recent years scholars have begun to question the usefulness of the category of ''religion'' to describe a distinctive form of human experience and behavior. In his last book, The Ideology of Religious Studies (OUP 2000), Timothy Fitzgerald argued that ''religion'' was not a private area of human existence that could be separated from the public realm and that the study of religion as such was thus impossibility. In this new book he examines a wide range of English-language texts to (...) show how religion became transformed from a very specific category indigenous to Christian culture into a universalist claim about human nature and society. These claims, he shows, are implied by and frequently explicit in theories and methods of comparative religion. But they are also tacitly reproduced throughout the humanities in the relatively indiscriminate use of ''religion'' as an a priori valid cross-cultural analytical concept, for example in historiography, sociology, and social anthropology. Fitzgerald seeks to link the argument about religion to the parallel formation of the ''non-religious'' and such dichotomies as church-state, sacred-profane, ecclesiastical-civil, spiritual-temporal, supernatural-natural, and irrational-rational. Part of his argument is that the category ''religion'' has a different logic compared to the category ''sacred,'' but the two have been consistently confused by major writers, including Durkheim and Eliade. Fitzgerald contends that ''religion'' imagined as a private belief in the supernatural was a necessary conceptual space for the simultaneous imagining of ''secular'' practices and institutions such as politics, economics, and the Nation State. The invention of ''religion'' as a universal type of experience, practice, and institution was partly the result of sacralizing new concepts of exchange, ownership, and labor practices, applying ''scientific'' rationality to human behavior, administering the colonies and classifying native institutions. In contrast, shows Fitzgerald, the sacred-profane dichotomy has a different logic of use. (shrink)

Over and above the probable peaking of worldwide oil production as a current reality, the arrival of hard limits on all energy resources is very much nearer in the future than many people realize.

In addition to scientific and technical analysts, thisgroup includes a fair number of generalists who have engaged in broader forms of (...) reflection upon the likely economic, social, political, and cultural effects of Peak Oil and other hard energy limits on the structure of current world civilization. In this paper, I select for examination three such generalists who are both especially talented and widely read by those having an interest in this topic: James Howard Kunstler, John Michael Greer, and Dmitri Orlov. My intention is to survey their central ideas in turn, with a view to forming a reasonably well-developed and concrete notion as to how the impending arrival of hard limits on energy consumption will affect the structure of built space in coming decades. I focus both on the macro-infrastructural level and on what one might term the micro-infrastructural level of the built space within which the denizens of contemporary industrial civilization live their daily lives. Theprincipal focus of the discussion will be on the situation in the United States, though many of the lines of argument presented may be applied much more broadly if suitably adjusted in light of locally prevailing conditions elsewhere.

“ Xin 心 (Mind)” is one of the key concepts in the four chapters of Guanzi . Together with Dao, qi 气 (air, or gas) and de 德 (virtue), the four concepts constitute a complete system of the learning of mind which is composed of the theory of benti 本体 (root and body), the theory of practice and the theory of spiritual state. Guanzi differentiates the two basic layers of mind—the essence and the function. It tries to attain a state (...) of accumulated jing 精 (essence, anima) and nourished qi , in which qi is concentrated in a miraculous way, through a series of methods of mind cultivation and nurturing, including being upright, calm, tranquil and moderate, and to concentrate the mind and intention. The doctrine of mind of the four chapters of Guanzi influenced Daoism and Confucianism and is a key link in the history of Chinese thought. It is a prelude to the merger of Confucianism, Daoism and Buddhism. (shrink)

Background: Patients in a vegetative state pose problems in diagnosis, prognosis and treatment. Currently, no prognostic markers predict the chance of recovery, which has serious consequences, especially in end-of-life decision-making. -/- Objective: We aimed to assess an objective measurement of prognosis using advanced electroencephalography (EEG). -/- Methods: EEG data (19 channels) were collected in 14 patients who were diagnosed to be persistently vegetative based on repeated clinical evaluations at 3 months following brain damage. EEG structure parameters (amplitude, duration and (...) variability within quasi-stationary segments, as well as the spatial synchrony between such segments and the strength of this synchrony) were used to predict recovery of consciousness 3 months later. -/- Results: The number and strength of cortical functional connections between EEG segments were higher in patients who recovered consciousness (P < .05 – P < .001) compared with those who did not recover. Linear regression analysis confirms that EEG structure parameters are capable of predicting (P = .0025) recovery of consciousness 6 months post-injury, whereas the same analysis failed to significantly predict patient outcome based on aspects of their clinical history alone (P = .629) or conventional EEG spectrum power (P = .473). -/- Conclusions: The result of this preliminary study demonstrates that structural strategy of EEG analysis is better suited for providing prognosis of consciousness recovery than existing methods of clinical assessment and of conventional EEG. Our results may be a starting point for developing reliable prognosticators in patients who are in vegetative state, with the potential to improve their day-to-day management, quality of life, and access to early interventions.

Peg Rawes examines a "minor tradition" of aesthetic geometries in ontological philosophy. Developed through Kant’s aesthetic subject she explores a trajectory of geometric thinking and geometric figurations--reflective subjects, folds, passages, plenums, envelopes and horizons--in ancient Greek, post-Cartesian and twentieth-century Continental philosophies, through which productive understandings of space and embodies subjectivities are constructed. Six chapters, explore the construction of these aesthetic geometric methods and figures in a series of "geometric" texts by Kant, Plato, Proclus, Spinoza, Leibniz, Bergson, Husserl and Deleuze. (...) In each text, geometry is expressed as a uniquely embodies aesthetic activity because each respective geometric method and figure is imbued with aesthetic sensibility and geometric sense (rather than as disembodies scientific methods). An ontology of aesthetic geometric methods and figures is therefore traced from Kant’s Critical writings, back to Plato and Proclus Greek philosophy, Spinoza and Leibniz’s post-Cartesian philosophies, and forwards to Bergson’s "duration" and Husserl’s "horizons" towards Deleuze’s philosophy of sense.

The author proposes a dimensional model of our emotion concepts that is intended to be largely independent of one’s theory of emotions and applicable to the different ways in which emotions are measured. He outlines some conditions for selecting the dimensions based on these motivations and general conceptual grounds. Given these conditions he then advances an 8-dimensional model that is shown to effectively differentiate emotion labels both within and across cultures, as well as more obscure expressive language. The 8 dimensions (...) are: (1) attracted—repulsed, (2) powerful—weak, (3) free—constrained, (4) certain—uncertain, (5) generalized—focused, (6) future directed—past directed, (7) enduring—sudden, (8) socially connected—disconnected.

The paper explores the role played by concepts of temporality in shaping the self's identity and its moral responsibility. This theme is examined in both Kant and Benjamin, two theorists who view the modern self as an essentially historical being. For Kant, teleological and uniform time shoulders the heightening of the self's universal attributes and the constant expansion of a moral community. The desired end is the establishment of an integrated and homogeneous human space, a cosmopolitan stage wherein history is (...) finally redeemed. This progressive notion of time is seen as dangerous by Benjamin, since it generates forgetfulness and inner impoverishment of the self. Instead, Benjamin advances a fragmented conception of time, one allowing conversation between distant moments and grounding identity in concrete images. While the poetic recovery of memory leads to the distinct and exclusive, Benjamin follows Kant in demanding universal moral responsibility of the self. However, Benjamin's strategy, so to speak, is the integration of our temporal - not spatial - experience. Key Words: Benjamin • history • Kant • nation-state • space • time. (shrink)

Newton's arguments for the immobility of the parts of absolute space have been claimed to licence several proposals concerning his metaphysics. This paper clarifies Newton, first distinguishing two distinct arguments. Then, it demonstrates, contrary to Nerlich ([2005]), that Newton does not appeal to the identity of indiscernibles, but rather to a view about de re representation. Additionally, DiSalle ([1994]) claims that one argument shows Newton to be an anti-substantivalist. I agree that its premises imply a denial of a kind of (...) substantivalism, but I show that they are inconsistent with Newton's core doctrine that not all motion is the relative motions of bodies, and so conclude that they are not part of his considered views on space.

The present paper aims to contribute to the substantivalism versus relationalism debate and to defend general relativity (GR) against pseudoscientific attacks in a novel, especially inclusive way. This work was initially motivated by the desire to establish the incompatibility of any ether theories with accelerated cosmic expansion and inflation (motto: where would a hypothetical medium supposedly come from so fast?). The failure of this program is of interest for emergent GR concepts in high energy particle physics. However, it becomes increasingly (...) important to guard scientific results against their misrepresentation by fundamentally anti-scientific agendas. We therefore argue that although it is not known whether the perceived space-time is fundamental (rather than a condensed state or a particular membrane), in a fundamental theory, space-time must be abstract relational: fundamental space-time is the consistent spatial-temporal arrangement of events. To pursue its own goals, this work should be accessible to a wide audience: physicists, philosophers of science, those being tempted by anti-relativity theories, but also those who vigorously defend some orthodox relativity that is not actually supported by GR. It must thus be extensive in order to satisfy the different parties’ desire to have included and understood their respective positions. (shrink)

Existential space is lived space, space permeated by our raced, gendered selves. It is representative of our very existence. The purpose of this essay is to explore the intersection between this lived space and art by analyzing the work of the Cuban?born artist Ana Mendieta and showing how her Siluetas Series discloses a space of exile. The first section discusses existential spatiality as explained by the phenomenologists Heidegger and Watsuji and as represented in Mendieta's Siluetas. The second section analyzes the (...) space of exile as a space of in?between?ness and borders. Lastly, the third section discusses temporality as it relates to the space of exile. Through the analysis of Mendieta's Siluetas, and in light of phenomenological accounts of space and the works of Anzaldúa and Mignolo, Ana Mendieta herself is disclosed as well as the space characteristic of those who can no longer be said to have a ?home.? My exploration through my art of the relationship between myself and nature has been a clear result of my having been torn from my homeland during my adolescence. The making of my Silueta in nature keeps (makes) the transition between my homeland and my new home. It is a way of reclaiming my roots and becoming one with nature.

The current widespread belief that taxonomic methods used before Darwin were essentialist is ill-founded. The essentialist method developed by followers of Plato and Aristotle required definitions to state properties that are always present. Polythetic groups do not obey that requirement, whatever may have been the ontological beliefs of the taxonomist recognizing such groups. Two distinct methods of forming higher taxa, by chaining and by examplar, were widely used in the period between Linnaeus and Darwin, and both generated polythetic (...) groups. Philosopher William Whewell congratulated pre-Darwinian taxonomists for not adhering to the rigid ideal of definition used in the mathematical sciences. What he called the method of types is here called the method of exemplars because typology has been equated with essentialism, whereas the use of a type species as the reference point or prototype for a higher category was a practice inconsistent with essentialism. The story that the essentialism of philosophers dominated the development of systematics may prove to be a myth. (shrink)

This article is concerned to formulate some open problems in the philosophy of space and time that require methods characteristic of mathematical traditions in the foundations of geometry for their solution. In formulating the problems an effort has been made to fuse the separate traditions of the foundations of physics on the one hand and the foundations of geometry on the other. The first part of the paper deals with two classical problems in the geometry of space, that of (...) giving operationalism an exact foundation in the case of the measurement of spatial relations, and that of providing an adequate theory of approximation and error in a geometrical setting. The second part is concerned with physical space and space-time and deals mainly with topics concerning the axiomatic theory of bodies, the operational foundations of special relativity and the conceptual foundations of elementary physics.

I argue that, although we are inherently intersubjective beings, we are not first or most originally “public” beings. Rather, to become a public being, that is, a citizen—in other words, to act as an independent and self-controlled agent in a community of similarly independent and self-controlled agents and, specifically, to do so in a shared space in the public arena—is something that we can successfully do only by emerging from our familiar, personal territories—our homes. Finding support in texts from philosophy, (...) psychology, and the social sciences, I construe the claim that citizenship is a developed stance as a spatial issue. I conclude that a state (or, for that matter, a philosophy) that takes the human being to begin as an isolated individual agent fails to recognize the essential spatial relationships on which we depend—namely, those arising through our way of being-at-home in the world; and, as a result, such a stance not only misconstrues the parameters on which citizenship is itself possible but also risks developing a social situation that encourages behaviors we see in the agoraphobic—namely, the behaviors of alienated and fundamentally homeless human beings.

In this paper I offer a fresh interpretation of Leibniz’s theory of space, in which I explain the connection of his relational theory to both his mathematical theory of analysis situs and his theory of substance. I argue that the elements of his mature theory are not bare bodies (as on a standard relationalist view) nor bare points (as on an absolutist view), but situations . Regarded as an accident of an individual body, a situation is the complex of its (...) angles and distances to other co-existing bodies, founded in the representation or state of the substance or substances contained in the body. The complex of all such mutually compatible situations of co-existing bodies constitutes an order of situations , or instantaneous space. Because these relations of situation change from one instant to another, space is an accidental whole that is continuously changing and becoming something different, and therefore a phenomenon. As Leibniz explains to Clarke, it can be represented mathematically by supposing some set of existents hypothetically (and counterfactually) to remain in a fixed mutual relation of situation, and gauging all subsequent situations in terms of transformations with respect to this initial set. Space conceived in terms of such allowable transformations is the subject of Analysis Situs. Finally, insofar as space is conceived in abstraction from any bodies that might individuate the situations, it encompasses all possible relations of situation. This abstract space , the order of all possible situations , is an abstract entity, and therefore ideal. (shrink)

My objective in this paper is to address a handful of issues that typically get raised in discussions of philosophical anarchism. Some of these issues arise in discussions among partisans of anarchism, and some are more likely to be raised in efforts to defend the state against its opponents.

The paper gives a physicist's view on the framework of branching space-time (Belnap, Synthese 92 (1992), 385--434). Branching models are constructed from physical state assignments. The models are then employed to give a formal semantics for the modal operators ``possibly'' and ``necessarily'' and for the counterfactual conditional. The resulting formal language can be used to analyze quantum correlation experiments. As an application sketch, Stapp's premises LOC1 and LOC2 from his purported proof of non-locality (Am. J. Phys. 65 (1997), 300--304) are (...) analyzed. (shrink)

The technique of minimizing information (infomin) has been commonly employed as a general method for both choosing and updating a subjective probability function. We argue that, in a wide class of cases, the use of infomin methods fails to cohere with our standard conception of rational degrees of belief. We introduce the notion of a deceptive updating method and argue that non-deceptiveness is a necessary condition for rational coherence. Infomin has been criticized on the grounds that there are no (...) higher order probabilities that ‘support’ it, but the appeal to higher order probabilities is a substantial assumption that some might reject. Our elementary arguments from deceptiveness do not rely on this assumption. While deceptiveness implies lack of higher order support, the converse does not, in general, hold, which indicates that deceptiveness is a more objectionable property. We offer a new proof of the claim that infomin updating of any strictly-positive prior with respect to conditional-probability constraints is deceptive. In the case of expected-value constraints, infomin updating of the uniform prior is deceptive for some random variables but not for others. We establish both a necessary condition and a sufficient condition (which extends the scope of the phenomenon beyond cases previously considered) for deceptiveness in this setting. Along the way, we clarify the relation which obtains between the strong notion of higher order support, in which the higher order probability is defined over the full space of first order probabilities, and the apparently weaker notion, in which it is defined over some smaller parameter space. We show that under certain natural assumptions, the two are equivalent. Finally, we offer an interpretation of Jaynes, according to which his own appeal to infomin methods avoids the incoherencies discussed in this paper. (shrink)

This article analyses the rhetorical legitimation strategy of post-Soviet Uzbekistan under Islam Karimov as an authoritarian state. I show that the most important mode of legitimation in this case is neither the consequentialist appeal to stability, order or welfare, nor a direct appeal to guardianship, i.e., special knowledge. Rather, Karimov and his court intellectuals seek to advance a conception of 'ideology' as the comprehensive pre-political consensus of the political community. Their concept of 'ideology' is used to advance a political logic (...) whereby the nature of the political community, the purpose of the state, the unifying political telos and the present regime are fused into a single entity. This ontological fusion is presented as a hegemonic reality and occurs at the pre-political level, resulting in the vanishingly small space left over for politics that characterizes authoritarian systems. I then suggest that such analysis of the hegemonic strategy of authoritarian regimes, and above all the teleological conception of politics it advances, is a superior approach to authoritarian legitimation than the search for explicit 'consequentualist' versus 'principled' arguments.

In this essay I analyze some conceptual difficulties associated with the demand that global institutions be made more democratically accountable. In the absence of a world state, it may seem inconsistent to insist that global institutions be accountable to all those subject to their decisions while also insisting that the members of these institutions, as representatives of states, simultaneously remain accountable to the citizens of their own countries for the special responsibilities they have towards them. This difficulty seems insurmountable in (...) light of the widespread acceptance of a state-centric conception of human rights, according to which states and only states bear primary responsibility for the protection of their citizens' rights. Against this conception, I argue that in light of the current structures of global governance the monistic ascription of human rights obligations to states is no longer plausible. Under current conditions, states are bound to fail in their ability to protect the human rights of their citizens whenever potential violations either stem from transnational regulations or are perpetrated by non-state actors. In order to show the plausibility of an alternative, pluralist conception of human rights obligations I turn to the current debate among scholars of international law regarding the human rights obligations of non-state actors. I document the various ways in which these obligations could be legally entrenched in global financial institutions such as the WTO, the IMF and the World Bank. These examples indicate feasible methods for strengthening the democratic accountability of these institutions while also respecting the accountability that participating member states owe to their own citizens. I conclude that, once the distinctions between the obligations to respect, protect and fulfill human rights are taken into account, no conceptual difficulty remains in holding states and non-state actors accountable for their respective human rights obligations.

Universal Grammar (UG) can be interpreted as a constraint on the form of possible grammars (hypothesis space) or as a constraint on acquisition strategies (selection procedures). In this response to Herschensohn we reiterate the position outlined in Epstein et al. (1996a, r), that in the evaluation of L2 acquisition as a UG- constrained process the former (possible grammars/ knowledge states) is critical, not the latter. Selection procedures, on the other hand, are important in that they may have a bearing on (...) development in language acquisition. We raise the possibility that differences in first and second language acquisition pertaining to both attainment of the end-state and course of development may derive from differences in selection procedures. We further suggest that for these reasons age effects in the attainment of nativelike proficiency must necessarily be separated from UG effects. (shrink)

The sets of contexts and properties of a concept are embedded in the complex Hilbert space of quantum mechanics. States are unit vectors or density operators, and contexts and properties are orthogonal projections. The way calculations are done in Hilbert space makes it possible to model how context influences the state of a concept. Moreover, a solution to the combination of concepts is proposed. Using the tensor product, a procedure for describing combined concepts is elaborated, providing a natural solution to (...) the pet fish problem. This procedure allows the modeling of an arbitrary number of combined concepts. By way of example, a model for a simple sentence containing a subject, a predicate and an object, is presented.

Most historians of science eagerly acknowledge that the early modern period witnessed a shift from a prevailing Aristotelian, spherical, centered conception of space to a prevailing Cartesian, rectilinear, oriented spatial framework. Indeed, this shift underlay many of the important advances for which the period is celebrated. However, historians have failed to engage the general conceptual shift, focusing instead on the particular explanatory developments that resulted. This historical lacuna can be attributed to a historiographical problem: the lack of an adequate unit (...) of analysis by which to investigate the conceptual change. Here, a philosophical argument is made for representations of space as an appropriate category of historical investigation, and methods of textual interrogation are suggested to this end. Finally, two examples, taken from Aristotle and Newton, demonstrate the feasibility and importance of this project. (shrink)

Wilfrid Sellars employs the metaphor of the space of reasons to express a certain conception of knowledge: “in characterising an episode or state as that of knowing … one is placing it in the logical space of reasons, of justifying and being able to justify what one says”.1 A growing number of philosophers employ the same metaphor to express a conception of at least some (other) mental states: in characterising a state as that of belief, or intention, one is placing (...) it in the same logical space.2 The burden of Alan Millar’s characteristically careful and thought-provoking book is to tell us what this conception amounts to, and to argue for its truth. Its central claim is that the concepts of belief and intention, and what they are concepts of, are (in a sense to be explained) normative. Chapter four – “the heart of the book”, in Millar’s view3 – is devoted to explaining, and defending this claim. (shrink)

The effective reasoning capability of an agent can be defined as its capability to infer, within a given space and time bound, facts that are logical consequences of its knowledge base. In this paper we show how to determine the effective reasoning capability of an agent with limited memory by encoding the agent as a transition system and automatically verifying whether a state where the agent believes a certain conclusion is reachable from the start state. We present experimental results using (...) the Model Based Planner (MBP) which illustrates how the length of the deduction varies for different memory sizes. (shrink)

This quoted passage makes a negative claim – a claim about what we are not doing when we characterize an episode or state as that of knowing – and it also makes a positive claim – a claim about what we are doing when we characterize an episode or state as that of knowing. Although McDowell has not endorsed the negative claim, he has repeatedly and explicitly endorsed the positive claim, i.e., that “in characterizing an episode or a state as (...) that of knowing… we are placing it in the logical space of reasons, of justifying and being able to justify what one says.” This is what I will henceforth call “the positive Sellarsian claim”.

A landmark study in the field of political science, The Changing Architecture of Politics charts the profound structural changes taking place in the late twentieth-century state. Looking at both theory and practice, Cerny argues that political structures--states in the broadest sense--are the key to understanding both the history and the future of modern politics. Included for discussion are such salient topics as the problem of locating institutional and structural theory within political and social science, how to describe and classify the (...) main elements of political structures, and a penetrating analysis of the structured action field that lies at the crossroads of political structuration. In addition, he explores several core areas in practice, including how states will operate in the next century and how states will interact with the manifold changes in social and economic processes--at both the domestic and international levels. Through his masterly portrayal of the architecture of contemporary politics, Cerny lays the foundations for an understanding of new political structures that are needed if the pursuit of human values is to continue into the next century. As such, this fascinating volume will appeal to all those interested in the paradigms of political and social science, whether from a purely theoretical or from a more empirical standpoint. "This is the best introduction available in English to contemporary academic discussions about the purpose and prospects of applying the comparative method to political science. Cerny's book is comprehensive in scope and accomplishes three, quite rare tasks: it brings together material on North America, Western Europe, and Japan; it combines theories of comparative politics and international relations; it pays equal attention to systems of party competition and of interest intermediation, although its primary focus is upon the state. Philip Cerny has produced a tour de force, an intelligent, erudite, and comprehensive text that cuts decisively through artificial barriers within the discipline." --Political Science Quarterly.

The “surge in use of finite-state methods” ([10]) in computational linguistics has largely, if not completely, left semantics untouched. The present paper is directed towards correcting this situation. Techniques explained in [1] are applied to a fragment of temporal semantics through an approach we call finite-state temporality. This proceeds from the intuition of an event as “a series of snapshots” ([15]; see also [12]), equating snapshots with symbols that collectively form our alphabet. A sequence of snapshots then becomes a (...) string over that alphabet, evoking comic/film strips. Jackendoff has, among others, objected to conceptualizing events in terms of snapshots ([8]). To counter these objections, we step up from events-as-strings to event-typesas-regular languages ([5, 6]), recognizing the need for variable granularity. Beyond the introduction of disjunction implicit in the step from a single string up to a set of strings, we obtain a useful logic from the regular operations and a careful choice of the snapshots (constituting our alphabet).

This paper considers the interpretive significance of the intersecting relationships between different conceptions of responsibility as they shift over space and time. The paper falls into two main sections. The first gives an account of several conceptions of responsibility: two conceptions founded in ideas of capacity; two founded in ideas of character, and one founded in the relationship between an agent and the outcome which she causes. The second main section uses this differentiated conceptual account to analyse and interpret certain (...) aspects of the contemporary criminal law of England and Wales. In conclusion, the paper considers a number of hypotheses about what the evidence of certain shifts in the relationship between the three families of responsibility-conception can tell us about the current state and significance of criminal law among other systems of social governance.

Finite-state methods are applied to the Russell-Wiener-Kamp notion of time (based on events) and developed into an account of interval relations and semi-intervals. Strings are formed and collected in regular languages and regular relations that are argued to embody temporal relations in their various underspecified guises. The regular relations include retractions that reduce computations by projecting strings down to an appropriate level of granularity, and notions of containment for partiality within and across such levels.

This is the first of two papers responding (somewhat belatedly) to ‘recent’ commentary on various aspects of hyperplane dependence (HD) by several authors. In this paper I focus on the issues of the relations of HD to state reduction and unitary evolution. The authors who’s comments I address here are Maudlin and Myrvold. In the second paper of this set I focus on HD dynamical variables and localizable properties and measurements and address comments of de Koning, Halvorson, Clifton and (...) Wallace. Each paper ends with some reflections on the implications of HD for the ontology of Minkowski space-time. To set the stage for my responses, I begin this paper with some general position statements designed to correct what seem to be widespread and erroneous construals of some of my views. Two central points are argued for in this first paper. First, dynamical evolution occurs not only within foliations of Minkowski space-time. Rather the transition from the physical state of affairs on any one hyperplane to any other, whether the hyperplanes intersect or are parallel, is always an instance of dynamical evolution between them, generated by some active combination of boost-like transformations and/or time-like translations and/or state reductions and ‘reconstructions’. This point gives rise to a generalized conception of a history of dynamical evolution, allowing for the use of parameterized families of hyperplanes that multiply cover some portions of space-time. Nevertheless, and this is the second central point, for any two generalized histories, H and H’, the quantum states for a system on all the hyperplanes of H from the asymptotic past up to some hyperplane, h, determine the quantum states for the system on all the hyperplanes of H’ from the asymptotic past up to any hyperplane, h’, such that h’ lies to the past of all those state reduction regions that lie to the future of all hyperplanes of H that are ‘earlier’ than h. Consideration of these results should defuse concerns that have been voiced about the coherence and consistency of HD. A position closely related to the second point (albeit restricted to the comparison of histories confined to foliations) has already been argued for by Myrvold (2002). (shrink)

The focus of this paper is two-fold. First, similarities generated from six semantic models were compared to human ratings of paragraph similarity on two datasets—23 World Entertainment News Network paragraphs and 50 ABC newswire paragraphs. Contrary to findings on smaller textual units such as word associations (Griffiths, Tenenbaum, & Steyvers, 2007), our results suggest that when single paragraphs are compared, simple nonreductive models (word overlap and vector space) can provide better similarity estimates than more complex models (LSA, Topic Model, SpNMF, (...) and CSM). Second, various methods of corpus creation were explored to facilitate the semantic models’ similarity estimates. Removing numeric and single characters, and also truncating document length improved performance. Automated construction of smaller Wikipedia-based corpora proved to be very effective, even improving upon the performance of corpora that had been chosen for the domain. Model performance was further improved by augmenting corpora with dataset paragraphs. (shrink)

The methods of experiments in the social sciences should depend on their purposes. To support this claim, I attempt to state some general principles relating method to purpose for three of the issues addressed. (I do not understand what is not a script, so I will omit that issue.) I illustrate my outline with examples from psychological research on judgment and decision making (JDM).

This paper constitutes a critical exploration of the functional features underpinning the unconscious of institutional attachment—namely an attachment which is understood in terms of the subject-infant’s love for his institutional parent-power holder, and the indefinite need for a subject to remain within its infantile condition under the parenthood of the State. We venture beyond the Paternal metaphor and move towards the neglected metaphor of the Mother, so focal in the individual process of identification, assumption of language and the permanent attachment (...) to the space of prohibition and Law. A new position in Language is defined. To understand how the psychic space of the infant is artfully subjugated in the making of the Western culture and domination of the Western system of legal interpretation, an enquiry into the legal emblematic history of representations is necessary to map the process through which the subject learns its legal self and relationship with otherness through what Pierre Legendre coined as the Occidental Mirror and the triangular logic of reflexivity. A final enquiry interrogates the way the legal institution places itself in the position of the specular image that captivates the subject-infant within a procreated legal order, a law-giving and law abiding life starting from the laws of the familial structure reinforced by the role of the parents and by analogy, by the State assuming that role in the institutional life of the ad infinitum infant.

I aim to clarify the argument for space that Newton presents in De Gravitatione (composed prior to 1687) by putting Newton's remarks into conversation with the account of geometrical knowledge found in Proclus's Commentary on the First Book of Euclid's Elements (ca. 450). What I highlight is that both Newton and Proclus adopt an epistemic progression (or “order of knowing”) according to which geometrical knowledge necessarily precedes our knowledge of metaphysical truths concerning the ontological state of affairs. As I argue, (...) Newton's commitment to this order of knowing clarifies the interplay of the imagination and understanding in geometrical inquiry and illuminates how geometrical knowledge of space can lead to knowledge that space depends on and is related to God. In general, appreciating the Proclean elements of Newton's argument brings added light to the significance of geometrical inquiry for his general natural philosophical program and grants us insight into the philosophical grounding for the notion of absolute space that is presented in the Principia mathematica (1687).

Finite-state methods are applied to determine the consequences of events, represented as strings of sets of fluents. Developed to flesh out events used in natural language semantics, the approach supports reasoning about action in AI, including the frame problem and inertia. Representational and inferential aspects of the approach are explored, centering on conciseness of language, context update and constraint application with bias.

The work of René Girard invites us to re-imagine a ‘religious–secular’ interactivity within social space in a way released from the violent dualisms of the ‘sacred/profane.’ Earlier Dietrich Bonhoeffer considered the same task and suggested directions for a positive theology of church-state relations, even as the inherited forms of these institutions were collapsing about him. This paper explores the Girardian scenario for church and state becoming rivalrous ‘doubles’– whether it be secular utopic projects doubling religious narratives of redemption, or churches (...) doubling the state as parallel yet purer societies – and suggests resources from Bonhoeffer by which a non-rivalrous church-state relationality - both mutually-constituting and mutually-limiting - may be configured.

Biologists studying short-lived organisms have become aware of the need to recognize an explicit temporal extend of a population over a considerable time. In this article we outline the concept and the realm of populations with explicit spatial and temporary boundaries. We call such populations “temporally bounded populations”. In the concept, time is of the same importance as space in terms of a dimension to which a population is restricted. Two parameters not available for populations that are only spatially defined (...) characterise temporally bounded populations: total population size, which is the total number of individuals present within the temporal borders, and total residence time, which is the sum of the residence times of all individuals. We briefly review methods to estimate these parameters. We illustrate the concept for the large blue butterfly (Maculinea nausithous) and outline insights into ecological and conservation-relevant processes that cannot be gained without the use of the concept.

A tissue is a geometrical, space-filling, random cellular network; it remains in this steady state while individual cells divide. Cell division is a local, elementary topological transformation which establishes statistical equilibrium of the structure. We describe the physical conditions to maintain stationary the epidermis (of mammals or of the cucumber), in spite of the fact that cells constantly divide and die. Specifically, we study the statistical equilibrium of the basal layer, a corrugated surface filled with cells, constituting a two-dimensional topological (...) froth. Cells divide and detach from the basal layer, and these two topological transformations are responsible for the stationary state of the epidermis. The topological froth is capable of responding rapidly and locally to external constraints, and is a good illustration of the plasticity of random cellular networks.Statistical equilibrium is controlled by entropy, both as a measure of disorder and as information, and is characterized by observable relations between average cell shapes and sizes. The technique can be applied to any random cellular network in dynamical equilibrium. Mitosis as the dominating topological transformation and the fact that the distribution of cell shapes is very narrow are the only inputs specific to biology. (shrink)

In this paper I will present conceptions of state reduction and particle and/or system localization which render these subjects fully compatible with the general requirements of a relativistic, i.e. Lorentz invariant, quantum theory. The approach consists of a systematic generalization of the concepts of initial data assignment at definite times, initiation and completion of measurements at definite times, and dynamical evolution as time dependence, to the concepts of initial data assignment on arbitrary space-like hyperplanes, initiation and completion of measurements (...) on arbitrary space-like hyperplanes, and dynamical evolution as space-like hyperplane dependence, respectively. I also briefly discuss the superluminal propagation which emerges from the localization study and the manner in which causal anomalies are nevertheless avoided. (shrink)

New discoveries about materials and solar energy raise the possibility of a long-tenn shift of mining, refining, and manufacturing from Earth’s surface to locations outside Earth’s ecosphere, allowing Earth to begin to relax back toward its natural state. A little-discussed ambivalence toward the potential of space exploration exists among environmentalists. One camp sees it as a human adventure that may allow a bold initiative to improve Earth; another camp shies away from “heavy technology” and thus distrusts efforts as massive as (...) space exploration or utilization. Due to impending resource depletion on Earth, we may have only until the mid-twenty-first century to pursue the promising potential of space exploration to alleviate environmental problems of Earth. Subsequently, there may be too litde industlial base to support vigorous exploration and exploitation of resources in space. (shrink)

I begin with an appeal to the GHZ/Mermin state to illustrate the allure of contextualism and value-definiteness. I then point out that standard contextualism, with its special status for non-degenerate operators, faces some embarrassing questions. Further, there is an alternative that apparently does not have the same problems. A modest re-pasting of Hilbert space makes the honors almost even between these two varieties. The paper closes with some reflections on the peculiarities of contextualism.

Abstract State Machines (ASMs) provide a formal method for transparent design and specification of complex dynamic systems. They combine advantages of informal and formal methods. Applications of this method motivate a number of computability and decidability problems connected to ASMs. Such problems result for example from the area of verifying properties of ASMs. Their high expressive power leads rather directly to undecidability respectively uncomputability results for most interesting problems in the case of unrestricted ASMs. Consequently, it is rather natural (...) to ask whether there exist expressive classes of ASMs for which we can prove positive decidability and computability results. In this work, we introduce such a class of ASMs. The concept is similar to the one of the guarded fragment of first-order logic. We analyze the expressive power of this class and prove that it is stronger than Datalog LITE and the guarded fragment of first-order fixed point logic. Some decidability and computability results have been proven in earlier works. (shrink)

This collection of essays by 13 well-known contributors departs from a conventional analysis of the state that universalizes and standardizes what the state is, does, and means. The contributors engage state and stateness as it is encountered in everyday life, ranging from village and urban life to big dams, war, torture, hospital treatment, cinema attendance, and art exhibitions. The essays locate the state in time, space, and circumstance so that it is contingent and evocative rather than definitive and authoritative. The (...) study discusses formative discourses on the state, what we may think or say about the state, and what images are evoked by its various manifestations through social and cultural forms. This volume begins with a non-essentialist perspective on state formation, and concludes with an account of how the state is experienced in the post-9/11 world scenario, in India and South Asia, the US, Europe, including the former Soviet Union, and the Far East.

Attitudes in Britain to forests and trees are changing. Plantation forests - the product of the 'strategic reserve of timber' vision that held sway in the early twentieth century, and was turned into a physical reality by the Forestry Commission - are no longer fashionable. Today's forests are required to be sustainable, multi-purpose, and biologically diverse. They are expected to possess a 'spirit of place', be aesthetically pleasing, and help alleviate poverty and social exclusion in cities and remote rural areas. (...) This book traces the changing fortune of forests and trees in Britain and people's changing relations with them. It investigates traditional woodland management practices, and considers how they came to be supplanted by scientific forestry knowledge and methods. It examines the development of the Forestry Commission and its body of foresters, looks at the symbolic function of forests and trees, and assesses the claim that present day forestry has become a postmodern phenomenon. -/- A Critical Geography of Britain's State Forests will prove useful not only to foresters and nature conservationists, but to all those who are interested in how human beings socially and biophysically construct the environment, driven by a constant urge to find their place and meaning within it.

Cladistic analyses are based on the distinction between primitive and derived character states (hypotheses of the polarity of evolutionary transformations) and a complete reliance on only derived character state distributions as bona fide evidence of holophyletic assemblages of taxa. The cladistic premise that only derived character state distributions provide evidence of holophyly is reconsidered and shown to be both unjustified and inconsistent with the desire or methodological prescription of using all the available evidence. Cladistic techniques are here viewed primarily as (...) methods for the ordering of character states so that they may be differentially weighted. The problem of assigning realistic differential weight to primitive and derived character state distributions is briefly discussed. One possible use of primitive character state distributions as evidence of holophyly that is largely free of the problem of weight is proposed. This application is illustrated with an example from the caecilian amphibians (Amphibia: Gymnophiona). (shrink)

Introduction. Whatever its underlying causes, even the description of the phenomenon of thought insertion, of the content of the delusion, presents difficulty. It may seem that the best hope of a description comes from a broadly cognitivist approach to the mind which construes content-laden mental states as internal mental representations within what is literally an inner space: the space of the brain or nervous system. Such an approach objectifies thoughts in a way which might seem to hold out the prospect (...) of describing the ''alienated'' relation to one's own thoughts that seems to be present in thought insertion.1 Method. Firstly, I examine the general structure of cognitivist accounts of intentional or content-laden mental states. I raise the general difficulty of explaining how free-standing, and thus world-independent, inner states can still have bearing on the outer world. Secondly, I briefly examine Frith's model for explaining thought insertion and other passivity phenomena by postulating a failure of an internal monitoring mechanism of inner states. I question what account can be given of non-pathological cases and raise two specific objects. Results. Cognitivist accounts of the mind face a general, and possibly insuperable, challenge: explaining the intentionality of mental states in non-intentional, non- question-begging terms. There have so far been no satisfactory solutions. Cognitivist accounts of passivity phenomena in terms of a failure of internal monitoring face two objections. Firstly, accounting for non-pathological cases generates an infinite regress. Secondly, no account can be given of the paradoxical nature of utterances of the form of Moore's paradox: ''it is raining but I do not believe it''. Conclusions. A cognitivist approach presents an alienated account of thought in normal, non-pathological cases and is no help in accounting for thought insertion. (shrink)

Recent years have seen increased interest in the question of whether it is possible to provide an evolutionary game theoretic explanation for certain kinds of social norms. These explanatory approaches often rely on the fact that, in certain evolutionary models, the basin of attraction of "fair" or "just" strategies occupies a certain percentage of the state space. I sketch a proof of a general representation theorem for a large class of evolutionary game theoretic models played on a social network, in (...) the hope that this will contribute to a greater understanding of the basins of attraction of such models -- and hence the evolution of social norms. More precisely, I show how many kinds of social networks can be translated into random boolean networks. The interesting and useful part of this result is that, for many social networks, one can find a bijection $f$ between the state space of the social network and the state space of the random boolean network, such that the state $S`$ follows the state $S$ under the dynamical laws of the social network if and only if $f(S`)$ follows the state $f(S)$ under the dynamics of the random boolean network. In some cases, it is not possible to find such a bijection; in these cases, one can find an injection $f$ with the property that if $S`$ follows $S$ under the dynamics of the social network, then $f(S`)$ follows $f(S)$ under the dynamics of the random boolean network. I then use this method to catalog all the basins of attraction for some simple two-strategy games (the prisoner`s dilemma and the stag hunt) played on a ring, drawing on the work of Wuensche and Lesser (1992).

If connectionism is to be an adequate theory of mind, we must have a theory of representation for neural networks that allows for individual differences in weighting and architecture while preserving sameness, or at least similarity, of content. In this paper we propose a procedure for measuring sameness of content of neural representations. We argue that the correct way to compare neural representations is through analysis of the distances between neural activations, and we present a method for doing so. We (...) then use the technique to demonstrate empirically that different artificial neural networks trained by backpropagation on the same categorization task, even with different representational encodings of the input patterns and different numbers of hidden units, reach states in which representations at the hidden units are similar. We discuss how this work provides a rebuttal to Fodor and Lepore's critique of Paul Churchland's state space semantics. (shrink)

In place of earlier instrumentalist and phenomenalist interpretations of science both Quine and Sellars have developed highly influential realist positions centering around the doctrine that accepting a theory as explanatory and irreducible rationally entails accepting the entities posited by the theory. A growing reaction against this realism is partially based on perceived inadequacies in the doctrines of Quine and Sellars, but even more on reconstructions of scientific explanations which do not involve such ontic commitments. Three types of anti-realistic positions are (...) considered and criticized. Hesse's neo-Duhemian position couples a statistical theory of inference to a downgrading of purely theoretical statements. Sneed uses the method of axiomatrization through set-theoretic predicates to supply a reconstruction of Kuhn's account of scientific development. Here Ramsey-reduction sentences serve to eliminate purely theoretical terms. The longest section deals with van Fraassen's semantic model based on a state-space representation of scientific theories and the use of this model in interpreting quantum mechanics. It is argued that the model is valuable, but that the anti-realist interpretation accorded it is not justified and entails serious inconsistencies. (shrink)

The present article is devoted to the problem which is debated actively to-day, namely whether Greek poleis and the Roman Republic were early states or they represented a specific type of stateless societies. In particular, Moshe Berent examines this problem by the example of Athens in his contribution to this volume. He arrives at the conclusion that Athens was a stateless society. However, I am of the opinion that this conclusion is wrong: and I believe that Athens and Rome were (...) early states. Therefore the present article is in many respects a direct discussion with Berent (as well as with other supporters of this idea). (shrink)

In the philosophical literature on mental states, the paradigmatic examples of mental states are beliefs, desires, intentions, and phenomenal states such as being in pain. The corresponding list in the psychological literature on mental state attribution includes one further member: the state of knowledge. This article examines the reasons why developmental, comparative and social psychologists have classified knowledge as a mental state, while most recent philosophers--with the notable exception of Timothy Williamson-- have not. The disagreement is traced back to a (...) difference in how each side understands the relationship between the concepts of knowledge and belief, concepts which are understood in both disciplines to be closely linked. Psychologists and philosophers other than Williamson have generally have disagreed about which of the pair is prior and which is derivative. The rival claims of priority are examined both in the light of philosophical arguments by Williamson and others, and in the light of empirical work on mental state attribution. (shrink)

I take up Kant's remarks about a "transcendental deduction" of the "concepts of space and time" (A87/B119-120). I argue for the need to make a clearer assessment of the philosophical resources of the Aesthetic in order to account for this transcendental deduction. Special attention needs to be given to the fact that the central task of the Aesthetic is simply the "exposition" of these concepts. The Metaphysical Exposition reflects upon facts about our usage to reveal our commitment to the idea (...) that these concepts refer to pure intuitions. But the legitimacy of these concepts still hangs in the balance: these concepts may turn out to refer to nothing real at all. The subsequent Transcendental Exposition addresses this issue. The objective validity of the concepts of space and time, and hence their transcendental deduction, hinges on careful treatment of this last point. (shrink)

Presenting the history of space-time physics, from Newton to Einstein, as a philosophical development DiSalle reflects our increasing understanding of the connections between ideas of space and time and our physical knowledge. He suggests that philosophy's greatest impact on physics has come about, less by the influence of philosophical hypotheses, than by the philosophical analysis of concepts of space, time, and motion and the roles they play in our assumptions about physical objects and physical measurements. This way of thinking leads (...) to new interpretations of the work of Newton and Einstein and the connections between them. It also offers new ways of looking at old questions about a priori knowledge, the physical interpretation of mathematics, and the nature of conceptual change. Understanding Space-Time will interest readers in philosophy, history and philosophy of science, and physics, as well as readers interested in the relations between physics and philosophy. (shrink)

Hilary Putnam has argued that computational functionalism cannot serve as a foundation for the study of the mind, as every ordinary open physical system implements every finite-state automaton. I argue that Putnam's argument fails, but that it points out the need for a better understanding of the bridge between the theory of computation and the theory of physical systems: the relation of implementation. It also raises questions about the class of automata that can serve as a basis for understanding the (...) mind. I develop an account of implementation, linked to an appropriate class of automata, such that the requirement that a system implement a given automaton places a very strong constraint on the system. This clears the way for computation to play a central role in the analysis of mind. (shrink)

It is argued that Nozick's experience machine thought experiment does not pose a particular difficulty for mental state theories of well-being. While the example shows that we value many things beyond our mental states, this simply reflects the fact that we value more than our own well-being. Nor is a mental state theorist forced to make the dubious claim that we maintain these other values simply as a means to desirable mental states. Valuing more than our mental states is compatible (...) with maintaining that the impact of such values upon our well-being lies in their impact upon our mental lives. (shrink)

b>: The problem of how physical systems, such as brains, come to represent themselves as subjects in an objective world is addressed. I develop an account of the requirements for this ability that draws on and refines work in a philosophical tradition that runs from Kant through Peter Strawson to Gareth Evans. The basic idea is that the ability to represent oneself as a subject in a world whose existence is independent of oneself involves the ability to represent space, and (...) in particular, to represent oneself as one object among others in an objective spatial realm. In parallel, I provide an account of how this ability, and the mechanisms that support it, are realized neurobiologically. This aspect of the article draws on, and refines, work done in the neurobiology and psychology of egocentric and allocentric spatial representation. (shrink)

Here are two ways space might be (not the only two): (1) Space is “pointy”. Every finite region has infinitely many infinitesimal, indivisible parts, called points. Points are zero-dimensional atoms of space. In addition to points, there are other kinds of “thin” boundary regions, like surfaces of spheres. Some regions include their boundaries—the closed regions—others exclude them—the open regions—and others include some bits of boundary and exclude others. Moreover, space includes unextended regions whose size is zero. (2) Space is “gunky”.1 (...) Every region contains still smaller regions—there are no spatial atoms. Every region is “thick”—there are no boundary regions. Every region is extended. Pointy theories of space and space-time—such as Euclidean space or Minkowski space—are the kind that figure in modern physics. A rival tradition, most famously associated in the last century with A. N. Whitehead, instead embraces gunk.2 On the Whiteheadian view, points, curves and surfaces are not parts of space, but rather abstractions from the true regions. Three different motivations push philosophers toward gunky space. The first is that the physical space (or space-time) of our universe might be gunky. We posit spatial reasons to explain what goes on with physical objects; thus the main reason.. (shrink)

This paper examines connections between concepts of space and extension on the one hand and immaterial spirits on the other, specifically the immanentist concept of spirits as present in rerum natura. Those holding an immanentist concept, such as Thomas Aquinas, typically understood spirits non-dimensionally as present by essence and power; and that concept was historically linked to holenmerism, the doctrine that the spirit is whole in every part. Yet as Aristotelian ideas about extension were challenged and an actual, infinite, dimensional (...) space readmitted, a dimensionalist concept of spirit became possible—that asserted by the mature Henry More, as he repudiated holenmerism. Despite More’s intentions, his dimensionalist concept opens the door to materialism, for supposing that spirits have parts outside parts implies that those parts could in principle be mapped onto the parts of divisible bodies. The specter of materialism broadens our interest in More’s unconventional ideas, for the question of whether other early modern thinkers, including Isaac Newton, followed More becomes a question of whether they too unwittingly helped usher in materialism. This paper shows that More’s attack upon holenmerism fails. He illegitimately injects his dimensionalist concept of spirit into the doctrine, failing to recognize it as a consequence of the non-dimensionalist concept of spirit, which in itself secures indivisibility. The interpretive consequence for Newton is that there is no prima facie reason to suppose that the charitable interpretation takes him to deny holenmerism. (shrink)

In this article, I argue that if one closely follows Hobbes' line of reasoning in Leviathan, in particular his distinction between the second and the third law of nature, and the logic of his contractarian theory, then Hobbes' state of nature is best translated into the language of game theory by an assurance game, and not by a one-shot or iterated prisoner's dilemma game, nor by an assurance dilemma game. Further, I support Hobbes' conclusion that the sovereign must always punish (...) the Foole, and even exclude her from the cooperative framework or take her life, if she defects once society is established, which is best expressed in the language of game theory by a grim strategy. That is, compared to existing game-theoretic interpretations of Hobbes, I argue that the sovereign plays a grim strategy with the citizens once society is established, and not the individuals with one another in the state of nature.

The first full-length study in English of Hegel's political philosophy. In order to present an overall view of the development of Hegel's political thinking the author has drawn on Hegel's philosophical works, his political tracts and his personal correspondence. Professor Avineri shows that although Hegel is primarily thought of as a philosopher of the state, he was much concerned with social problems and his concept of the state must be understood in this context.

Space and time are the most fundamental features of our experience of the world, and yet they are also the most perplexing. Does time really flow, or is that simply an illusion? Did time have a beginning? What does it mean to say that time has a direction? Does space have boundaries, or is it infinite? Is change really possible? Could space and time exist in the absence of any objects or events? What, in the end, are space and time? (...) Do they really exist, or are they simply the constructions of our minds? Robin Le Poidevin provides a clear, witty, and stimulating introduction to these deep questions and many other mind-boggling puzzles and paradoxes. He gives a vivid sense of the difficulties raised by our ordinary ideas about space and time, but he also gives us the basis to think about these problems independently, avoiding large amounts of jargon and technicality. His book is an invitation to think philosophically rather than a sustained argument for particular conclusions, but Le Poidevin does advance and defend a number of controversial views. He argues, for example, that time does not actually flow, that it is possible for space and time to be both finite and yet be without boundaries, and that causation is the key to an understanding of one of the deepest mysteries of time: its direction. Drawing on a variety of vivid examples from science, history, and literature, Travels in Four Dimensions brings to life some of the most profound questions imaginable. (shrink)

In ANARCY, STATE AND UTOPIA Robert Nozick says that the fundamental question of political philosophy, one that precedes questions about how the state should be organized, is whether there should be any state at all. In the first part of his book he attempts to justify the state. We argue that he is not successful.

The claim of this paper is that we should envisage physicalism as an ontological holism. Our current basic physics, quantum theory, suggests that, ontologically speaking, we have to assume one global quantum state of the world; many of the properties that are often taken to be intrinsic properties of physical systems are in fact relations, which are determined by that global quantum state. The paper elaborates on this conception of physicalism as an ontological holism and considers issues such as supervenience, (...) realization of higher-order properties by basic physical properties, and reduction. Keywords: physicalism, holism, relations, space-time, quantum physics, Humean supervenience. (shrink)

Kant argued that the perceptual representations of space and time were templates for the perceived spatiotemporal ordering of objects, and common to all modalities. His idea is that these perceptual representations were specific to no modality, but prior to all—they are pre-modal, so to speak. In this paper, it is argued that active perception—purposeful interactive exploration of the environment by the senses—demands premodal representations of time and space.

One of the most significant political philosophers of the twentieth century, Carl Schmitt is a deeply controversial figure who has been labeled both Nazi sympathizer and modern-day Thomas Hobbes. First published in 1938, The Leviathan in the State Theory of Thomas Hobbes used the Enlightenment philosopher’s enduring symbol of the protective Leviathan to address the nature of modern statehood. A work that predicted the demise of the Third Reich and that still holds relevance in today’s security-obsessed society, this volume will (...) be essential reading for students and scholars of political science. “Carl Schmitt is surely the most controversial German political and legal philosopher of this century. . . . We deal with Schmitt, against all odds, because history stubbornly persists in proving many of his tenets right.”— Perspectives on Political Science “[A] significant contribution. . . . The relation between Hobbes and Schmitt is one of the most important questions surrounding Schmitt: it includes a distinct, though occasionally vacillating, personal identification as well as an association of ideas.”— Telos.
