This paper explores principles governing the rational balance among an agent's beliefs, goals, actions, and intentions. Such principles provide specifications for artificial agents, and approximate a theory of human action (as philosophers use the term). By making explicit the conditions under which an agent can drop his goals, i.e., by specifying how the agent is committed to his goals, the formalism captures a number of important properties of intention. Specifically, the formalism provides analyses for Bratman's three characteristic functional roles played (...) by intentions [7, 9], and shows how agents can avoid intending all the foreseen side-effects of what they actually intend. Finally, the analysis shows how intentions can be adopted relative to a background of relevant beliefs and other intentions or goals. By relativizing one agent's intentions in terms of beliefs about another agent's intentions (or beliefs'), we derive a preliminary account of interpersonal commitments. (shrink)

What is involved when a group of agents decide to do something together? Joint action by a team appears to involve more than just the union of simultaneous individual actions, even when those actions are coordinated. We would not say that there is any teamwork involved in ordinary automobile traffic, even though the drivers act simultaneously and are coordinated (one hopes) by the traffic signs and rules of the road. But when a group of drivers decide to do something together, (...) such as driving somewhere as a convoy, it appears that the group acts more like a single agent with beliefs, goals, and intentions of its own, over and above the individual ones.

A central problem in applying logical knowledge representation formalisms to traditional robotics is that the treatment of belief change is categorical in the former, while probabilistic in the latter. A typical example is the fundamental capability of localization where a robot uses its noisy sensors to situate itself in a dynamic world. Domain designers are then left with the rather unfortunate task of abstracting probabilistic sensors in terms of categorical ones, or more drastically, completely abandoning the inner workings of sensors (...) to black-box probabilistic tools and then interpreting their outputs in an abstract way. Building on a first-principles approach by Bacchus, Halpern and Levesque, and a recent continuous extension to it by Belle and Levesque, we provide an axiomatization that shows how localization can be realized wrt a basic action theory, thereby demonstrating how such capabilities can be enabled in a single logical framework. We then show how the framework can also enable localization for multiple agents, where an agent can appeal to the sensing already performed by another agent and the knowledge of their relative positions to localize itself.

This chapter argues that recent attempts to make sense of the delusion of thought insertion in terms of a distinction between two notions of thought ownership have been unsuccessful. It also proposes an alternative account, in which the delusion is to be interpreted in the light of its prehistory.

Si l’on connaît aujourd’hui le dialogue fructueux que Paul Ricœur a noué avec les penseurs structuralistes, on ignore largement son positionnement face à la mouvance poststructuraliste. Faut-il opposer la philosophie de Ricœur au poststructuralisme à la française ou au contraire doit-on montrer qu’elle en est une variante singulière? C’est la seconde option qui est ici défendue. Certes, le poststructuralisme ne doit pas être considéré comme une école de pensée mais comme une reconstruction qui relève de l’histoire de la philosophie. Dans (...) la mesure où les horizons de dépassement du structuralisme ont été posés de manière chaque fois particulière, il est préférable de parler de poststructuralismes au pluriel. C’est la raison pour laquelle J. Michel propose des confrontations dyadiques entre Ricœur et certains de ses contemporains que l’on regroupe habituellement dans cette mouvance. (shrink)

Noam Chomsky and Frances Egan argue that David Marr’s computational theory of vision is not intentional, claiming that the formal scientific theory does not include description of visual content. They also argue that the theory is internalist in the sense of not describing things physically external to the perceiver. They argue that these claims hold for computational theories of vision in general. Beyond theories of vision, they argue that representational content does not figure as a topic within formal computational theories (...) in cognitive science. I demonstrate that Chomsky’s and Egan’s claims about Marr’s theory are false. Marr’s computational theory contains a mathematical theory of visual content, based on empirical psychophysical evidence. It also contains mathematical descriptions of distal physical surfaces and objects, and of their optic projection to the perceiver. Much computational research on vision contains these types of intentional and externalist components within the formal, mathematical, theories. Chomsky’s and Egan’s claims demonstrate inadequate study and understanding of Marr’s work and other research in this area. Computational theories of vision, by containing empirically based mathematical theories of visual content, to this extent present naturalizations of semantics. (shrink)

The concept of joint action is at the core of numerous diverse research topics, including philosophical explorations of social action, studies of human dialogue, human-computer interaction, computer-supported collaborative work, multiagent systems, distributed artificial intelligence, distributed simulation, and contract law. It is therefore remarkable that so central a concept has received so little detailed analysis, in comparison with studies of individuals. However, in recent years, the study of joint action has begun to undergo more intense scrutiny, primarily from philosophers and researchers (...) in artificial intelligence. These two disciplines often address similar topics but with different motivations, methodologies, tools, and criteria for success. Although this paper is inspired by philosophical work, it is squarely motivated by the concerns of building intelligent systems that are capable of collaborative behavior, either with a user, or with other such systems. Still, we hope that the paper sheds light on philosophical issues, and treats the subject of joint action at a sufficiently precise level to be illuminating of problems that any philosophical account needs to confront.

Unter den Versuchen Fichtes, sein Denken allgemeinverständlich darzustellen, zählt diese 1800 erschienene Schrift zu den inhaltlich abgerundetsten und aufschlußreichsten; bei den Zeitgenossen stieß sie jedoch auf vehemente Kritik, Hegel sah in ihr gar einen besonders illustrativen Text für den Aufweis der Haltlosigkeit der von Fichte in der Wissenschaftslehre vertretenen Position einer auf das Ich als Tathandlung gegründeten Philosophie. Darum vermag allein schon die Lektüre von Fichtes Bestimmung des Menschen und ihrer kritischen Rezeption in Hegels Glauben und Wissen einen Einblick in (...) die Gründe zu vermitteln, warum bis ins 20. Jahrhundert die Philosophie Fichtes weitgehend als ein merkwürdiger Mosaikstein auf dem Wege "Von Kant bis Hegel" oder, im Hinblick auf den "Endpunkt" dieses Wegs wohl genauer, in der "Entwicklung des Spinozismus" betrachtet wurde. Deutlich wird einer neuen Lektüre aber auch, wieviel noch zu tun bleibt, um die wichtigen Erkenntnisse, die im Deutschen Idealismus auf so getrennten Bahnen gewonnen wurden, im Blick auf die gemeinsamen Grundprobleme einer "Ersten Philosophie" ohne Rückfall in die traditionellen Feindbilder wahrzunehmen und kritisch in die pluralistische Diskussion heutigen Philosophierens einzubringen.

We claim that adjustable parameters play a crucial role in building and applying simulation models. We analyze that role and illustrate our findings using examples from equations of state in thermodynamics. In building simulation models, two types of experiments, namely, simulation and classical experiments, interact in a feedback loop, in which model parameters are adjusted. A critical discussion of how adjustable parameters function shows that they are boon and bane of simulation. They help to enlarge the scope of simulation far (...) beyond what can be determined by theoretical knowledge, but at the same time undercut the epistemic value of simulation models. (shrink)

The display of artefacts always implies an external mediation that influences, and often codifies, the reception of the exhibits. Objects are manipulated, restored, appropriated, staged, in short displayed, through various representational strategies that include pedestals, labels, and showcases. These elements, that we could define as parerga, are often ignored because of their utilitarian function. Yet, they play an important role in the history of the artefacts and define the setting in which the objects can exert their agency. They not only (...) shape their meaning, but also determine the effect that these artefacts have on their viewers. Framing devices create the conditions for interactions between the individual and the object to take place. This publication aims to explore the relation between artefacts and viewers as they are manifested in framing devices, and to develop a new theoretical framework for thinking about the power of objects on display.

This chapter explores the ideological dimension of dehumanization in the context of National Socialism, focusing on the connection between concepts of humanity and dehumanizing images. NS regarded itself as a political revolution, realizing a new concept of humanity. Nazi ideologues undergirded the self-understanding of NS by developing racist anthropologies. I examine two major strands of Nazi ideology, focusing on their diverging strategies of dehumanization, and arguing that they were dependent on different anthropological frameworks. Richard Walther Darré held a naturalistic concept (...) of humanity and advanced biologistic forms of dehumanization. Alfred Rosenberg developed a dualistic anthropology that combined metaphysical and natural features. He dehumanized certain groups of people by reducing them to being human in a natural sense only. Moreover, I aim to show that the key motifs of these racist worldviews were prevalent in the scientific and philosophical debates on anthropology in early-twentieth-century Germany. I thus explore the general orientation of both the naturalistic and the anti-naturalistic strand in anthropological thought, unfold the animalizing tendencies of these views, and emphasize their conformity with the key motifs of Nazi ideology. The case of NS should thus exemplify the dehumanizing potential of anthropological theories. (shrink)

This paper describes an approach for reasoning in a dynamic domain with nondeterministic actions in which an agent’s beliefs correspond to the simplest, or most plausible, course of events consistent with the agent’s observations and beliefs. The account is based on an epistemic extension of the situation calculus, a first-order theory of reasoning about action that accommodates sensing actions. In particular, the account is based on a qualitative theory of nondeterminism. Our position is that for commonsense reasoning, the world is (...) most usefully regarded as deterministic, and that nondeterminism is an epistemic phenomenon, arising from an agent’s limited awareness and perception. The account offers several advantages: an agent has a set of categorical beliefs, yet can deal with equally-likely outcomes or with outcomes of differing plausibility. The agent maintains as its set of contingent beliefs the most plausible, or simplest, picture of the world, consistent with its beliefs and actions it believes it executed; yet it may modify these in light of later information.

Zunächst Pfarrer in Berlin-Charlottenburg, dann Professor für Philosophie in Halle, repräsentiert Eberhard die nachwolffianische deutsche Popularphilosophie, der an praktisch und pädagogisch wirksamer Aufklärung im Zusammenspiel mit den fortschrittlichen politischen und religiösen Kräften lag. In diesen Lehrbüchern repräsentiert Eberhard sich als Aufklärer auf dem philosophischen Niveau der ästhetischen, hermeneutischen und historischen Modifikation des Wolffschen Systems und der neuerlichen Rezeption der Philosophie Leibniz’, zumal der Erkenntnistheorie der 1765 erschienenen „Nouveaux essais sur l’entendement humain“. Eberhard wurde aufgrund seiner Theorie des Denkens und Empfindens (...) als Schüler Leibniz’ bezeichnet; und er verfasste denn auch eine Leibniz-Biographie. Er hielt zeitlebens an den wolffianischen Standards von Rationalität fest und widersetzte sich nicht nur dem normativen Rekurs auf „Empfindsamkeit“ in Literatur und Religion, sondern auch der sog. Glaubensphilosophie Friedrich Heinrich Jacobis, erst recht der zeitgenössischen Wiederkehr von Okkultismus und Esoterik. Johann August Eberhard, professor of philosophy in Halle, is one of the foremost exponents of the Popularphilosophie of the German Enlightenment. He was a major contributor to Friedrich Nicolai’s "Allgemeine Deutsche Bibliothek", and advanced unorthodox opinions on religious and political issues. (shrink)

1. Parmenides bis Hegel -- 2. Das 19. und 20. Jahrhundert.

Philosophers and historians have long been suspicious of modal and counterfactual claims. I argue, however, that historians often legitimately use modal and counterfactual claims for a variety of purposes. They help identify causes, and hence help explain events in history. They are used to defend judgments about people, and to highlight the importance of particular events. I defend these uses of modal claims against two arguments often used to criticize modal reasoning, using the philosophy of science to ground the truth (...) of modal claims. This analysis puts several important points into perspective, including how certain we can be about our claims about what might have been, and the role that determinism plays in those claims. The proper analysis of modality shows, I argue, that counterfactual claims are legitimate and important, if often uncertain, and that issues of determinism are irrelevant to the modal claims used in historical analysis.
