Perceptual tasks such as object matching, mammogram interpretation, mental rotation, and satellite imagery change detection often require the assignment of correspondences to fuse information across views. We apply techniques developed for machine translation to the gaze data recorded from a complex perceptual matching task modeled after fingerprint examinations. The gaze data provide temporal sequences that the machine translation algorithm uses to estimate the subjects' assumptions of corresponding regions. Our results show that experts and novices have similar surface behavior, such as (...) the number of fixations made or the duration of fixations. However, the approach applied to data from experts is able to identify more corresponding areas between two prints. The fixations that are associated with clusters that map with high probability to corresponding locations on the other print are likely to have greater utility in a visual matching task. These techniques address a fundamental problem in eye tracking research with perceptual matching tasks: Given that the eyes always point somewhere, which fixations are the most informative and therefore are likely to be relevant for the comparison task?

Forensic evidence often involves an evaluation of whether two impressions were made by the same source, such as whether a fingerprint from a crime scene has detail in agreement with an impression taken from a suspect. Human experts currently outperform computer-based comparison systems, but the strength of the evidence exemplified by the observed detail in agreement must be evaluated against the possibility that some other individual may have created the crime scene impression. Therefore, the strongest evidence comes from features in (...) agreement that are also not shared with other impressions from other individuals. We characterize the nature of human expertise by applying two extant metrics to the images used in a fingerprint recognition task and use eye gaze data from experts to both tune and validate the models. The Attention via Information Maximization model quantifies the rarity of regions in the fingerprints to determine diagnosticity for purposes of excluding alternative sources. The CoVar model captures relationships between low-level features, mimicking properties of the early visual system. Both models produced classification and generalization performance in the 75%–80% range when classifying where experts tend to look. A validation study using regions identified by the AIM model as diagnostic demonstrates that human experts perform better when given regions of high diagnosticity. The computational nature of the metrics may help guard against wrongful convictions, as well as provide a quantitative measure of the strength of evidence in casework. (shrink)

El debate entre liberalismo y perfeccionismo ha sido uno de los ejes centrales de la Filosofía política durante los últimos veinte años. Este libro aspira a analizar críticamente y, en última instancia, a ofrecer una defensa del núcleo conceptual de la posicíon liberal. A lo largo del trabajo, se examina y discute una amplia serie de argumentos propuestos por filósofos contemporáneos "Rawls, Larmore, Barry, Kymlicka, Nagel y Ackerman, entre otros" en defensa de la neutralidad estatal. A su vez, se desarrollan (...) dos líneas de argumentacíon en defensa de las posiciones liberales que pretenden superar las falencias analizadas a lo largo del libro. La meta del primer argumento es demostrar que quien acepte las ideas fundamentales de la cultura política de las democracias contemporáneas deberá aceptar también las ideas básicas del liberalismo. Su punto de partida es una formulacíon del ideal ético-político de igual respeto por las personas y una reinterpretacíon y ampliacíon de lo que Rawls ha denominado las "cargas del juicio". El segundo argumento toma como punto de partida una idea arraigada en la tradicíon de pensamiento liberal: la necesidad de reconocer la falibilidad humana y sus consecuencias políticas y morales. El argumento combina la apelacíon a una premisa falibilista con una distincíon entre razones para afirmar una creencia y razones para estar justificado a actuar a partir de ella en contextos en los que cometer un error acarrearía un daño grave a terceros. Sobre esta base, se señala una serie de ventajas de las políticas que satisfacen los requisitos de justificacíon neutrales frente a las políticas perfeccionistas. (shrink)

Mi meta en este trabajo es proponer un nuevo tipo de argumento en defensa del ideal deliberativo de reciprocidad de justificación —que fue inicialmente introducido por el liberalismo político de John Rawls—. Dicho argumento aspira a demostrar que, aun cuando aceptemos la hipótesis de que un grupo de ciudadanos dispone de una justificación pública apropiada para creer que determinada doctrina comprehensiva es verdadera o correcta, existen razones morales fundamentales para rechazar la pretensión de que el estado pueda estar justificado para (...) actuar sobre la base de esas creencias cuando las esencias constitucionales o cuestiones de justicia básica se encuentran en juego.

Helen Steward argues that determinism is incompatible with agency itself--not only the special human variety of agency, but also powers which can be accorded to animal agents. She offers a distinctive, non-dualistic version of libertarianism, rooted in a conception of what biological forms of organisation might make possible in the way of freedom.

James Tabery Helen Longino’s Studying Human Behavior is an overdue effort at a nonpartisan evaluation of the many scientific disciplines that study the nature and nurture of human behavior, arguing for the acceptance of the strengths and weaknesses of all approaches. After years of conflict, Longino makes the pluralist case for peaceful coexistence. Her analysis of the approaches raises the following question: how are we to understand the pluralistic relationship among the peacefully coexisting approaches? Longino is ironically rather unpluralistic (...) about her pluralism, forcing a choice between integrative pluralism and her preferred ineliminative pluralism. I hope to show that the analysis of approaches she offers actually accommodates a pluralism that is both integrative and ineliminative.Approaches to studying human behaviorPhilosophy of biology took shape as a discipline in the 1970s.

Helen Steward puts forward a radical critique of the foundations of contemporary philosophy of mind, arguing that it relies too heavily on insecure assumptions about the sorts of things there are in the mind--events, processes, and states. She offers a fresh investigation of these three categories, clarifying the distinctions between them, and argues that the category of state has been very widely and seriously misunderstood.

This is an important book precisely because there is none other quite like it.

Legitimidad política y neutralidad estatal puede ser considerado como un intento de responder a la pregunta que un defensor de una doctrina comprehensiva religiosa, filosófica o de la buena vida, podría realizarle a un Estado liberal: ¿por qué debo aceptar que las decisiones sobre políticas públicas se justifiquen por valores neutrales y no por los de la doctrina a la cual adhiero, los cuales considero como verdaderos y correctos? La importancia de una respuesta adecuada radica en que, de acuerdo con (...) Garreta Leclercq, uno de los principales objetivos del liberalismo contemporáneo, surgido a partir de la obra de John Rawls, consiste en brindar una conexión coherente entre tres ideas básicas: la de legitimidad política -según la cual los principios que guían el accionar estatal no deberían poder ser rechazados razonablemente por los ciudadanos razonables-, la de neutralidad de justificación -de acuerdo con la cual el Estado no debe apelar a la verdad de doctrinas comprehensivas para fundamentar su ejercicio del poder político - y la de persona razonable, es decir, un individuo que, por un lado, renuncia a usar el poder estatal para imponer su doctrina como verdadera y, por el otro, participa del esfuerzo cooperativo para alcanzar fundamentos políticos que sean independientes de la aceptación de una determinada doctrina comprehensiva.

A computer can come to understand natural language the same way Helen Keller did: by using “syntactic semantics”—a theory of how syntax can suffice for semantics, i.e., how semantics for natural language can be provided by means of computational symbol manipulation. This essay considers real-life approximations of Chinese Rooms, focusing on Helen Keller’s experiences growing up deaf and blind, locked in a sort of Chinese Room yet learning how to communicate with the outside world. Using the SNePS computational (...) knowledge-representation system, the essay analyzes Keller’s belief that learning that “everything has a name” was the key to her success, enabling her to “partition” her mental concepts into mental representations of: words, objects, and the naming relations between them. It next looks at Herbert Terrace’s theory of naming, which is akin to Keller’s, and which only humans are supposed to be capable of. The essay suggests that computers at least, and perhaps non-human primates, are also capable of this kind of naming. (shrink)

I have been asked to consider two questions: How Christian ‘oughts’ are related to Christian ‘is-es’, and, What does Christianity take flourishing to be? The background to these questions is that Christian ethics have traditionally been taken, both by supporters and opponents, as au ethic of creature-hood, sometimes quite crudely conceived. It is a sketch, but by no means a caricature, of a great deal of standard Christian thinking, to depict it as answering the two questions as follows: God is (...) your Creator: therefore you ought to obey him. The end of man is to glorify God and enjoy him for ever. (shrink)

The paper considers and opposes the view that processes are best thought of as continuants, to be differentiated from events mainly by way of the fact that the latter, but not the former, are entities with temporal parts. The motivation for the investigation, though, is not so much the defeat of what is, in any case, a rather implausible claim, as the vindication of some of the ideas and intuitions that the claim is made in order to defend — and (...) the grounding of those ideas and intuitions in a more plausible metaphysics than is provided by the continuant view. It is argued that in addition to a distinction between events and processes there is room and need for a third category, that of the individual process, which can be illuminatingly compared with the idea of a substance. Individual processes indeed share important metaphysical features with substantial continuants, but they do not lack temporal parts. Instead, it is argued that individual processes share with substantial continuants an important property I call ‘modal robustness in virtue of form’. The paper explains what this property is, and further suggests that the category of individual process, thus understood, might be of considerable value to the philosophy of action. (shrink)

The Ethics of War and Peace is a lively introduction to one of the oldest but still most relevant ethical debates. Focusing on the philosophical questions surrounding the ethics of modern war, Helen Frowe presents contemporary just war theory in a stimulating and accessible way. This 2nd edition includes new material on weapons and technology, and humanitarian intervention, in addition to: theories of self-defence and national defence jus ad bellum, jus in bello and jus post bellum the moral status (...) of combatants the principle of non-combatant immunity and the nature of terrorism and the moral status of terrorists. Each chapter uses examples and concludes with a summary, discussion questions and suggestions for further reading to aid student engagement, learning and revision. The glossary has been expanded to cover the full range of relevant terminology. This is the ideal textbook for students of philosophy and politics approaching this important area for the first time.

Most people believe that it is sometimes morally permissible for a person to use force to defend herself or others against harm. In Defensive Killing, Helen Frowe offers a detailed exploration of when and why the use of such force is permissible. She begins by considering the use of force between individuals, investigating both the circumstances under which an attacker forfeits her right not to be harmed, and the distinct question of when it is all-things-considered permissible to use force (...) against an attacker. Frowe then extends this enquiry to war, defending the view that we should judge the ethics of killing in war by the moral rules that govern killing between individuals. She argues that this requires us to significantly revise our understanding of the moral status of non-combatants in war. Non-combatants who intentionally contribute to an unjust war forfeit their rights not to be harmed, such that they are morally liable to attack by combatants fighting a just war. (shrink)

El presente artículo propone algunas objeciones contra la concepción deliberativa de la democracia desarrollada por Carlos Nino. El blanco central de las objeciones es la tesis del filósofo argentino según la cual el valor del debate democrático derivaría, fundamentalmente, de sus virtudes epistémicas, es decir, de su capacidad para elevar las probabilidades de que el sistema político tome las decisiones correctas. Se cuestiona el modo en que el autor presenta su propuesta como una forma de superar las deficiencias que presentarían (...) las concepciones de John Rawls y Jürgen Habermas en el campo de la epistemología moral. Se intentará demostrar que el modelo de deliberación defendido por Nino no resulta aplicable a un contexto de pluralismo razonable filosófico, religioso y moral como el que resulta característico de las democracias liberales contemporáneas. Por último, se ofrece el esbozo de una concepción alternativa, práctica y moral, no epistémica, del valor de los procedimientos democráticos y de la naturaleza de la legitimidad política. This paper posits some objections against the deliberative conception of democracy developed by Carlos Nino. According to Nino, the value of democratic deliberation lies, basically, in its epistemic virtues. Public deliberation increases the probability that the political system will arrive at the correct decisions. We shall argue that the Argentinean philosopher fails to prove that his proposal is a solution to purported weaknesses in John Rawls’ and Jürgen Habermas’ positions in the field of moral epistemology. We shall try to demonstrate that the conception of deliberation posited by nino cannot be applied successfully in the context of moral, philosophical or religious reasonable pluralism that characterizes liberal contemporary democracies. Finally, we offer an outline of an alternative conception -practical and moral, non epistemic- of the value of democratic procedures and about the nature of political legitimacy. (shrink)

El costo de tomar una decisión sobre la base de las creencias falsas varía en diferentes contextos de acción. En algunos casos el costo del error podría ser muy alto para el bienestar de los agentes afectados y en otros casos muy bajo. El contraste entre estos dos tipos de contextos ha sido recientemente objeto de atención en la epistemología. Mi objetivo en este trabajo es extender el análisis de algunas de las implicaciones de ese contraste al campo moral. En (...) particular, defenderé la tesis de que existen casos en los que un sujeto puede saber faliblemente que un curso de acción es el mejor desde una perspectiva moral y no estar, sin embargo, justificado a actuar sobre la base de ese conocimiento en el contexto en que se encuentra, dado el elevado costo que tendría que ese juicio fuese falso. Por lo tanto, en esos casos, existiría una brecha entre los conceptos de conocimiento moral y justificación moral de la acción. (shrink)

La meta del presente artículo es probar que existen contextos de acción en los que tiene lugar una escisión entre el conocimiento moral de los sujetos y la justificación, también moral, de sus acciones. Para que ello ocurra, según sostendremos, deben darse al menos dos condiciones: el costo de actuar sobre la base de creencias falsas debe ser muy elevado para el bienestar de los afectados y la probabilidad de que tal resultado se produzca efectivamente, aunque baja, debe ser significativa (...) o no trivial. Sostendremos que la escisión entre conocimiento y justificación de la acción referida tiene importantes consecuencias para la estructura de la deliberación moral. This paper is aimed at proving that in certain contexts of action there may be a cleavage between the moral knowledge of an agent and the moral justification of her actions. I will argue that this is so when two conditions obtain: first, acting on the basis of false beliefs may end-up being very costly in terms of the welfare of those affected; and second, even if low, the probability of such negative upshots are significant or not trivial. I shall claim that this cleavage between knowledge and justification of actions has important consequences for the structure of moral deliberation. (shrink)

The purpose of the following article is to sustain the view that accepting the basic notions of political liberalism does not necessarily lead to a minimalistic concept of global justice as that developed by John Rawls in The Law of Peoples. In opposition to his explicit opinion, I shall hold that -within the global political field- contemporary liberal democracies can publicly hold egalitarian ideals and a robust conception of human rights in order to justify some of the features of their foreign policy. I shall try to demonstrate that this is not incompatible with the required tolerance and respect toward nations that conspicuously embrace ways of life and belief systems incompatible with some of the most relevant liberal values.

En A Letter Concerning Toleration John Locke argumenta en favor de la tolerancia religiosa afirmando que el Estado no puede mejorar la vida de las personas forzándolas a vivir de acuerdo con creencias que ellas no suscriben. Más recientemente, Ronald Dworkin y Will Kymlicka han desarrollado argumentos similares. En el caso del primero, contra ciertas políticas paternalistas; en el del segundo, en apoyo de la tesis liberal de la neutralidad estatal. Mi propósito en el presente artículo es analizar la plausibilidad (...) de dichos argumentos concebidos como una defensa de la tesis de la neutralidad estatal. Intentaré demostrar que ambas versiones del argumento fracasan. En la sección II, cuestionaré la capacidad de los argumentos para respaldar las conclusiones que aspiran establecer, sin objetar la plausibilidad de las premisas involucradas. En la sección III, desarrollaré tres objeciones contra la concepción del bienestar crítico que constituye el corazón de ambas versiones del argumento. In A Letter Concerning Toleration, John Locke argues in favor of religious toleration positing that the state cannot make a person's life better by forcing that person to live according to beliefs he refuses. More recently, Ronald Dworkin and Will Kymlicka have developed similar arguments.

My aim in the present paper is to analyze the plausibility of these arguments conceived as a defense of liberal neutrality. I will prove that both versions of the argument fail. In section II, I will object the argument's capability to support the conclusions it attempts to establish, without raising doubts about the reliability of its premises. In section III, I will submit three objections against the conception of critical well-being that constitutes the core of both versions of the argument. (shrink)

ABSTRACT The supporters of political liberalism hold that the exercise of political power is legitimate only when it is justified by public reasons acceptable to all citizens, independently of the religious, philosophical, or moral doctrine they adhere to. In John Rawls' view, satisfying this conception of legitimacy makes it necessary to appeal to "political conceptions of justice" when attempting to publicly justify actions by the State. The article sets forth a new type of argument in favor of Rawls' position.

Helen Frowe has recently offered what she calls a “practical” account of self-defense. Her account is supposed to be practical by being subjectivist about permissibility and objectivist about liability. I shall argue here that Frowe first makes up a problem that does not exist and then fails to solve it. To wit, her claim that objectivist accounts of permissibility cannot be action-guiding is wrong; and her own account of permissibility actually retains an objectivist (in the relevant sense) element. In (...) addition, her attempt to restrict subjectivism primarily to “urgent” situations like self-defense contradicts her own point of departure and is either incoherent or futile. Finally, the only actual whole-heartedly objectivist account she criticizes is an easy target; while those objectivist accounts one finds in certain Western European jurisdictions are immune to her criticisms. Those accounts are also clearly superior to hers in terms of action-guidingness. (shrink)

The Habits of Racism examines some of the complex questions raised by the phenomenon and experience of racism. Helen Ngo argues that the conceptual reworking of habit as bodily orientation helps to identify the more subtle but fundamental workings of racism, exploring what the lived experience of racism and racialization teaches about the nature of the embodied and socially-situated being.

The paper argues that actions should be thought of as processes and not events. A number of reasons are offered for thinking that the things that it is most plausible to suppose we are trying to cotton on to with the generic talk of ‘actions’ in which philosophy indulges cannot be events. A framework for thinking about the event-process distinction which can help us understand how we ought to think about the ontology of processes we need instead is then developed, (...) building on some excellent work already done by philosophers working at the intersection of philosophy and linguistics.

In The Value of the Humanities prize-winning critic Helen Small assesses the value of the Humanities, eloquently examining five historical arguments in defence of the Humanities.

The paper argues that it is possible for an incompatibilist to accept John Martin Fischer's plausible insistence that the question whether we are morally responsible agents ought not to depend on whether the laws of physics turn out to be deterministic or merely probabilistic. The incompatibilist should do so by rejecting the fundamentalism which entails that the question whether determinism is true is a question merely about the nature of the basic physical laws. It is argued that this is a (...) better option for ensuring the irrelevance of physics than the embrace of semi-compatibilism, since there are reasons for supposing that alternate possibilities are necessary for moral responsibility, despite Fischer's claims to the contrary. There are two distinct reasons for supposing that alternate possibilities might be necessary for moral responsibility—one of which is to do with fairness, the other to do with agency itself. It is suggested that if one focuses on the second of these reasons, Fischer's arguments for supposing that alternate possibilities are unnecessary for moral responsibility can be met by the incompatibilist. Some possible reasons for denying that alternate possibilities are necessary for the existence of agency are then raised and rejected. (shrink)

In this paper, I explore the question what a continuant is, in the context of a very interesting suggestion recently made by Rowland Stout, as part of his attempt to develop a coherent ontology of processes. Stout claims that a continuant is best thought of as something that primarily has its properties at times, rather than atemporally—and that on this construal, processes should count as continuants. While accepting that Stout is onto something here, I reject his suggestion that we should (...) accept that processes are both occurrents and continuants; nothing, I argue, can truly occur or happen, which does not have temporal parts. I make an alternative suggestion as to how one might deal with the peculiar status of processes without jettisoning a very natural account of occurrence; and assess the consequences for the category of continuant.

This volume will be the starting point for future discussion and research.

This paper argues for the replacement of the Principle of Alternate Possibilities by an alternative principle, the Principle of Possible Non-Performance, which it is argued represents an important improvement on the Principle of Alternate Possibilities in the context of Frankfurt-style examples. The suggestion that the principle offers only the possibility of something insufficiently 'robust' to supply a decent replacement to PAP is countered.

Underdetermination arguments support the conclusion that no amount of empirical data can uniquely determine theory choice. The full content of a theory outreaches those elements of it (the observational elements) that can be shown to be true (or in agreement with actual observations).2 A number of strategies have been developed to minimize the threat such arguments pose to our aspirations to scientific knowledge. I want to focus on one such strategy: the invocation of additional criteria drawn from a pool of (...) cognitive or theoretical values, such as simplicity or generality, to bolster judgements about the worth of models, theories, and hypotheses. What is the status of such criteria? Larry Laudan, in Science and Values, argued that cognitive values could not be treated as self-validating, beyond justification, but are embedded in a three-way reticulational system containing theories, methods, and aims or values, which are involved in mutually supportive relationships (Laudan, 1984). My interest in this paper is not the purportedly self-validating nature of cognitive values, but their cognitive nature. Although Laudan rejects the idea that what he calls cognitive values are exempt from rational criticism and disagreement, he does seem to think that the reticulational system he identifies is independent of non-cognitive considerations. It is this cognitive/non-cognitive distinction that I wish to query in this paper. Let me begin by summarizing those of my own views about inquiry in which this worry about the distinction arises.
