I knew that this was a book a long time in the making, and one that bore the mark of many years of teaching the philosophy discussed in the work. As a publisher, you come to learn that those who have taught courses on what they’re writing about tend to do a better job than those who haven’t, especially when it comes to books, like this one, intended for a wider audience.

In this paper we argue that awareness comes in degrees, and we propose a novel multi-factor account that spans both subjective experiences and perceptual representations. At the subjective level, we argue that conscious experiences can be degraded by being fragmented, less salient, too generic, or flash-like. At the representational level, we identify corresponding features of perceptual representations—their availability for working memory, intensity, precision, and stability—and argue that the mechanisms that affect these features are what ultimately modulate the degree of awareness. (...) We conclude the paper by demonstrating why the original interpretations of certain empirical findings that apparently pose problems for our account are, in fact, flawed. (shrink)

Shows that the dialogue in Plato's Phaedo is primarily devoted to presenting Socrates' final defense of the philosophical life against the theoretical and political challenge of religion.

The principle of semantic compositionality, as Jerry Fodor and Ernie Lepore have emphasized, imposes constraints on theories of meaning that it is hard to meet with psychological or epistemic accounts. Here, I argue that this general tendency is exemplified in Michael Dummett's account of meaning. On that account, the so-called manifestability requirement has the effect that the speaker who understands a sentence s must be able to tell whether or not s satisfies central semantic conditions. This requirement is not met (...) by truth-conditional accounts of meaning. On Dummett's view, it is met by a proof conditional account: understanding amounts to knowledge of what counts as a proof of a sentence. A speaker is supposed always to be capable of deciding whether or not a given object is a proof of a given sentence she understands. This requirement comes into conflict with compositionality. If meaning is compositionally determined, then all you need for understanding a sentence is what you get from combining your understanding of the parts according to the mode of composition. But that knowledge is not always sufficient for recognizing any proof at all of a given sentence. Dummett's proof-theoretic argument to the contrary is mistaken. (shrink)

Realists and supporters of ‘democratic underlabouring’ have recently challenged the traditional separation between political theory and practice. Although both attack Jürgen Habermas for being an idealist whose philosophy is too removed from politics, I argue that this interpretation is inaccurate. While Habermas’s social and political theory is indeed oriented to truth and understanding, he has sought realize his communicative conception of democracy by increasing the quality of political debate as a public intellectual. Building on his approach, I argue that giving (...) the theorist a direct role in public policy undermines theory as an enterprise oriented towards truth while overlooking the contingency, participatory nature and complicated internal logics of social and political practice. My basic thesis is that Habermas’s understanding of the relationship between theory and practice overcomes these difficulties by providing an account of theory that is independent but simultaneously also allows philosophers to participate in politics as public intellectuals.

Generic statements play a crucial role in concept learning, communication and education. Despite many efforts, the semantics of generics remain a controversial issue, as they do not seem to fit our standard theories of meaning. In this article, we attempt to shed light on this problem by focusing on how these sentences function in reasoning. Drawing on a distinction between property and diagnostic generics, we defend three theses: First, property generics are not about facts but express relations between concepts. Second, (...) generics play an important role in everyday reasoning by interacting with our expectations about the world. Third, diagnostic generics emphasise properties that separate the category in the generics from other categories in the same contrast class. We use the theory of conceptual spaces to advance measures of typicality and diagnosticity capable of modelling different aspects of generics and apply them to the modifier effect and the inverse conjunction fallacy. Finally, we discuss the pragmatics of generics. (shrink)

Smiling is a universal human practice, although readiness to smile at strangers varies according to culture. In Australia, where being open and friendly to strangers is not unusual, the city of Port Phillip, an area covering some of the bayside suburbs of Melbourne, has been using volunteers to find out how often people smile at those who pass them in the street. It then put up signs that look like speed limits, but tell pedestrians that they are in, for example, (...) a “10 Smiles Per Hour Zone.â€. (shrink)

This article describes rational analyses and cognitive models of Web users developed within information foraging theory. This is done by following the rational analysis methodology of (a) characterizing the problems posed by the environment, (b) developing rational analyses of behavioral solutions to those problems, and (c) developing cognitive models that approach the realization of those solutions. Navigation choice is modeled as a random utility model that uses spreading activation mechanisms that link proximal cues (information scent) that occur in Web browsers (...) to internal user goals. Web‐site leaving is modeled as an ongoing assessment by the Web user of the expected benefits of continuing at a Web site as opposed to going elsewhere. These cost–benefit assessments are also based on spreading activation models of information scent. Evaluations include a computational model of Web user behavior called Scent‐Based Navigation and Information Foraging in the ACT Architecture, and the Law of Surfing, which characterizes the empirical distribution of the length of paths of visitors at a Web site.

Following Manne (1966, Insider Trading and the Stock Market (New York, Free Press)) we introduce a distinction between insider trading and market manipulation on the one hand and corporate insiders versus misappropriators on the other hand. This gives rise to four types of alleged inside transactions. We argue that the literature on insider trading has often targeted inside transactions type II, III and IV but that these arguments do not necessarily hold for type I transactions. We look for consequentionalist as (...) well as non-consequentionalist arguments against type I transactions and demonstrate that these are hard to find. Throughout the article we refer extensively to the economic literature on insider trading in order to overcome a relative divide between the economic, legal, and philosophical discussion on insider trading.

In this article, I analyze the circumstances of justice, that is, the background conditions that are necessary and sufficient for justice to exist between individual parties in society. Contemporary political philosophers almost unanimously accept an account of these circumstances attributed to David Hume. I argue that the conditions of this standard account are neither sufficient nor necessary conditions for justice. In particular, I contend that both a Hobbesian state of nature and a prisoner’s dilemma are cases in which the conditions (...) of the standard account obtain and yet no justice exists between parties. I propose an alternative set of generic circumstances of justice motivated by examples from game theory. Parties are in these generic circumstances with respect to each other when: (1) they are engaged in a conflictual coordination game with multiple strict Nash equilibrium points where, at any of these equilibria, some parties do not receive their greatest payoffs, and (2) they have common knowledge that each party is rational and follows her end of a strict equilibrium where no party receives her greatest payoff. These two conditions reflect the idea that justice requires all parties to make some sacrifices so that others can have more of the goods they need and want. I argue that these generic circumstances are necessary and sufficient conditions for parties to follow generic norms of justice, that is, mutually beneficial practices that require some sacrifices. Key Words: common knowledge • conflictual coordination • correlated equilibrium • moderate selfishness • moderate variable scarcity • rough equality. (shrink)

In the following, I concentrate on the nefarious, harmful and unethical dimensions emerging only slowly as the rather new phenomenon of cryptocurrencies and blockchain at large become visible only gradually. For the positive and pro-social use of cryptocurrencies please refer to the article of Claus Dierksmeier in this issue of HMJ. As there are many different dimensions still unknown, I concentrate on the ethical issues emerging from the secretive nature of cryptocurrencies, less on the environmental carbon footprint or economic implications (...) of volatility also discussed in the literature. Among the most critical issues are black market transactions of weapons used in terrorist attacks, drugs, or childpornography. Additionally, cryptocurrencies are more and more found in blackmailing people and as payment for ransom-ware and other computer viruses. Money laundering also is on the rise via cryptocurrencies. I argue that the nefarious use of cryptocurrencies threatens the prosocial potential of cryptocurrencies and in general makes criminal activity easier for criminals and less likely to track down by legal authorities. In closing, I discuss current debates about emerging regulation presenting an overview of some jurisdictions and the option of regulated central bank issues cryptocurrencies. (shrink)

The so called Ramsey test is a semantic recipe for determining whether a conditional proposition is acceptable in a given state of belief. Informally, it can be formulated as follows: (RT) Accept a proposition of the form "if A, then C" in a state of belief K, if and only if the minimal change of K needed to accept A also requires accepting C. In Gärdenfors (1986) it was shown that the Ramsey test is, in the context of some other (...) weak conditions, on pain of triviality incompatible with the following principle, which was there called the preservation criterion: (P) If a proposition B is accepted in a given state of belief K and the proposition A is consistent with the beliefs in K, then B is still accepted in the minimal change of K needed to accept A. (RT) provides a necessary and sufficient criterion for when a 'positive' conditional should be included in a belief state, but it does not say anything about when the negation of a conditional sentence should be accepted. A very natural candidate for this purpose is the following negative Ramsey test: (NRT) Accept the negation of a proposition of the form "if A, then C" in a consistent state of belief K, if and only if the minimal change of K needed to accept A does not require accepting C. This note shows that (NRT) leads to triviality results even in the absence of additional conditions like (P). (shrink)

This book looks at how scientists investigate the nature of the mind and the brain, providing answers to these important questions.

Contrary to common belief, IT systems often disappoint the expectations to increase productivity and flexibility of work and value creation processes. Moreover, most IT design and implementation projects still fail or burst time and cost budgets to a high extent. After presenting significant empirical evidence for these phenomena, the paper reflects on the reasons for their persistence by developing a semiotic perspective on the processes of dealing with computer artifacts in organisations. This semiotic view allows understanding the processes of designing, (...) implementing and using IT systems as efforts of structuring social practices in organisations. A typical case of enterprise resource planning system implementation illustrates this. Finally, a number of guidelines for an improved practice of designing and appropriating IT systems for effective use in organisations are derived from the theoretical reflections. (shrink)

Besides pure declarative arguments, whose premises and conclusions are declaratives (“you sinned shamelessly; so you sinned”), and pure imperative arguments, whose premises and conclusions are imperatives (“repent quickly; so repent”), there are mixed-premise arguments, whose premises include both imperatives and declaratives (“if you sinned, repent; you sinned; so repent”), and cross-species arguments, whose premises are declaratives and whose conclusions are imperatives (“you must repent; so repent”) or vice versa (“repent; so you can repent”). I propose a general definition of argument (...) validity: an argument is valid exactly if, necessarily, every fact that sustains its premises also sustains its conclusion, where a fact sustains an imperative exactly if it favors the satisfaction over the violation of the imperative, and a fact sustains a declarative exactly if, necessarily, the declarative is true if the fact exists. I argue that this definition yields as special cases the standard definition of validity for pure declarative arguments and my previously defended definition of validity for pure imperative arguments, and that it yields intuitively acceptable results for mixed-premise and cross-species arguments.

Participants of low and high hypnotic susceptibility were tested on a temporal order judgement task, both with and without hypnosis. Judgements were made of the order of presentation of light flashes appearing in first one hemi-field then the other. There were differences in the inter-stimulus intervals required accurately to report the order, depending upon which hemi-field led. This asymmetry was most marked in hypnotically susceptible participants and reversed when they were hypnotised. This implies not only that brain activity changes in (...) hypnosis, but also that there is a difference in brain function between people of low and high hypnotic susceptibility. The latter exhibited a faster-acting left hemisphere in the waking state, but faster right when hypnotised. (shrink)

While “meaning negotiation” has become an ubiquitous term, its use is often confusing. A negotiation problem implies not only a convenience to agree, but also diverging interest on what to agree upon. It implies agreement but also the possibility of disagreement. In this chapter, we look at meaning negotiation as the process through which agents starting from different preferred conceptual representations of an object, an event or a more complex entity, converge to an agreement through some communication medium. We shortly (...) sketch the outline of a geometric view of meaning negotiation, based on conceptual spaces. We show that such view can inherit important structural elements from game theoretic models of bargaining – in particular, in the case when the protagonists have overlapping negotiation regions, we emphasize a parallel to the Nash solution in cooperative game theory. When acceptable solution regions of the protagonists are disjoint, we present several types of processes: changes in the salience of dimensions, dimensional projections and metaphorical space transformations. None of the latter processes are motivated by normative or rationality considerations, but presented as argumentation tools that we believe are used in actual situations of conceptual disagreement.

Hai, Peter NV Lay people have always played a vital role in the life and mission of the church but it is only after the Second Vatican Council that the question of the laity has come into focus in a new way in Catholic theological reflection. Indeed, in the wake of Vatican II, the council that introduced a Copernican shift in the Catholic understanding of the laity, lay people have become the theme of a Synod of Bishops, the subject (...) of an Apostolic Exhortation, and the topic of several pastoral statements of national conferences of bishops. This paper begins with a review of the state of the question highlighting the need for a comparative investigation of the theologies of the laity according to John Paul II, the Federation of Asian Bishops' Conferences, and the Vietnamese Episcopal Conference. It then highlights the differences and convergences in these theologies. As all three theologies draw their inspiration from the teachings of Vatican II, and a prominent element of the council's concerns was the emphasis on the universal call to holiness, we will also provide a detailed comparison of this notable aspect across these theological systems. Our argument is that while some minor points of divergence and disagreement remain there is a greater convergence and agreement between these theologies of the laity. (shrink)

I explore heterogeneous constructionism, my term for the perspective that science in the making is a process of agents building by combining a diversity of components. Issues addressed include causality and explanation; transcending both realism and relativism; scientists as acting, intervening, and imaginative agents; explanations that span many levels of social practice; counterfactuals in the analysis of causal claims; and practical reflexivity. An analogy from research on the social origins of depression and a sketch from my own experience in socioeconomic (...) modeling are used to motivate and render more concrete the form of heterogeneous constructionism I am advocating.

This paper examines the points of disagreement between Neo-Darwinian and recent Neo-Aristotelian discussions of the status of purposive language in biology. I discuss recent Neo-Darwinian “evolutionary” treatments and distinguish three ways to deal with the philosophical status of teleological language of purpose: teleological error theory, methodological teleology, and Darwinian teleological realism. I then show how “non-evolutionary” Neo-Aristotelian approaches in the work of Michael Thompson and Philippa Foot differ from these by offering a view of purposiveness grounded in life-cycle patterns, rather (...) than in long-term evolutionary processes or natural selection. Finally, I argue that the crucial difference between Neo-Darwinian and Neo-Aristotelian approaches regards the question of whether or not reproduction deserves the status of an “ultimate” aim of organisms. I offer reasons to reject the concept of an “ultimate” aim in evolutionary biology and to reject the notion that reproduction serves a purpose. I argue that evolutionary biology is not in the position to determine what the “ultimate” explanation of natural purpose is. (shrink)

This paper considers Hermann Hesse’s novel, The Glass Bead Game, in the light of Paulo Freire’s educational philosophy. The Glass Bead Game is set in Castalia, a “pedagogical province” of the 23rd century. It is argued that the central character in the book, Joseph Knecht, undergoes a complex process of conscientisation. Knecht develops an increasingly critical understanding of Castalian society, questioning some of its most cherished assumptions while nonetheless deepening his appreciation of the beauty of the Glass Bead Game. He (...) becomes less certain of his certainties as he grows older, and eventually decides to give away his prestigious post as Magister Ludi (Master of the Glass Bead Game) to pursue a quiet life as a tutor. Dialogue plays a key role in the development of Knecht’s critical consciousness. Freirean theory is seen to provide a robust framework for the analysis of key themes in Hesse’s text. At the same time, The Glass Bead Game is helpful in demonstrating the meaning and significance of conscientisation and dialogue for educational lives. (shrink)

Paulo Freire and Lorenzo Milani are considered as key figures in a number of Southern European countries for providing signposts for a critical approach to education. In this paper I will view their ideas and biographical trajectories comparatively to glean some important insights for a critical pedagogy. The common theme throughout this comparative analysis is that of education for social justice based on critical literacy. The paper also deals with such themes as the relationship between education and politics, the relationship (...) between education and life, the collective dimension of learning and the ability to read as well as write the word and the world.
