In a growing number of papers, one encounters arguments to the effect that certain philosophical views are objectionable because they would imply that there are necessary truths for whose necessity there is no explanation. That is, they imply that there are propositions p such that (a) it is necessary that p, but (b) there is no explanation why it is necessary that p. For short, they imply that there are “brute necessities.” Therefore, the arguments conclude, the views in question should (...) be rejected in favor of rival views under which the necessities would be explained. This style of argument raises a number of important and difficult questions. Do necessary truths really require explanation? Are they not paradigms of truths that either need no explanation or automatically have one, being in some sense self‐explanatory? If some necessary truths do require or admit of explanation, what types of explanation, are available? Are some necessary truths explained by other necessary truths? Are some necessary truths self‐explanatory? Are all necessary truths either self‐explanatory or explained by others? Or are there some necessary truths that are truly brute? This article surveys several representative arguments from brute necessity as well as a variety of answers to the questions above, noting their bearing on arguments from bruteness. (shrink)

In this book, he argues that the purpose of democracy should be to promote justice - we need not just democracy (in the sense of unqualified democracy) but a just democracy. Machiavelli and Rawls must be brought together.

Philosophers of mind have not in general been very attentive to metaphysics. This book is a salutary exception to this general observation. A philosopher of mind—at least the body of her very influential work would be classified by most philosophers as belonging to the philosophy of mind—attempts to ground a theory of the relation between human persons and their bodies in an extended essay on the metaphysics of the natural world. Baker is a materialist : in her book, you and (...) I and everyone we know is a material thing. But then how are we material persons related to our bodies, which are also material things? Unlike many materialists, she rejects the following answer to this question: We are identical with our bodies. The bulk of this review is no more than a summary of her answer to the “person-body question.” My summary will use language very different from hers, since it will rely heavily on the language of parthood, and she is extremely hostile to any attempt to use the concept “part” in connection with her theory. Nevertheless, the use I make of this concept is innocuous, and my representation of her answer to the person-body question is accurate. (shrink)

In this paper I home in on an ethical phenomenon that is powerfully elucidated by means of enactive resources but that has, to my knowledge, not yet been explicitly addressed in the literature. The phenomenon in question concerns what I will term the paradox of moral perception, which, to be clear, does not refer to a logical but to a phenomenological-practical paradoxicality. Specifically, I have in mind the seemingly contradictory phenomenon that perceiving persons as moral subjects is at once incredibly (...) easy and incredibly difficult; it is something we do nearly effortlessly and successfully all the time without giving it much thought and it is something that often requires effort and that we fail at all the time. As I will argue, enactivism offers distinctive resources for explaining the paradoxical nature of moral perception. These resources, moreover, bring out two important dimensions of ethical life that are frequently overlooked in contemporary ethical theory: namely the embodied and socio-technical environment-embedded dimensions of moral perception and moral visibility. As I make my argument, I will be connecting enactivism with insights from David Hume’s and Iris Murdoch’s moral philosophy as well as insights from the field of Epistemic Injustice. As such, I aim to situate enactivism within the larger theoretical ethical landscape; showing connections with existing ethical theories and identifying some of the ways in which enactivism offers unique contributions to our understanding of ethical life. While doing so, I will furthermore introduce two forms of moral misperception: particular moral misperception and categorial moral misperception. (shrink)

Recently, research into gender differences in achievement has mainly concentrated on the underperformance of boys in comparison with girls. Qualitative research in particular points to the importance of the gender-specific cultures adolescents experience. The purpose of this article is to test quantitatively the explanatory value of academic culture with respect to the stated gender differences in achievement. Use is made of data of 3760 pupils in the third and the fourth year of secondary education in a sample of 34 schools (...) in Flanders (Belgium). A distinction is made between general schools preparing students for higher education and schools offering technical and vocational education. It is demonstrated that boys' culture is less study oriented than girls' culture and that this difference can be held responsible for the gender differences in achievement, at least in general schools. In technical/vocational schools, boys seem to oppose the study culture. (shrink)

Gödel once offered an argument for the general reflection principle in set theory that took the form of an analogy with Leibniz' Monadology. I discuss the mathematical and philosophical background to Gödel's argument, reconstruct the proposed analogy in detail, and argue that it has no justificatory force.

Performance measurement systems have the potential to improve organizational outcomes, but they often come at a cost. This commentary highlights the individual, organizational, and societal costs of performance measurement systems and explores how such costs could be reduced.

Rational agents base their actions on information from observation, inference, introspection, or other sources. But this information comes in different kinds, and it is usually handled by different logical mechanisms. We discuss how to integrate external ‘updating information’ and internal ‘elucidating information’ into one system of dynamic epistemic logic, by distinguishing two basic informational actions: ‘bare seeing’ versus ‘conscious realization’.

The empirical-transcendental debate in philosophy of technology, as debates go, took a turn toward the counterposing of the two perspectives, ‘empirical’-pragmatic-pragmatist versus ‘transcendental’-critical. Postphenomenology aligns itself with the former standpoint, and it is in this spirit that commentators have criticized it for its too-instrumentalist stance and lack of overarching, i.e., transcendental orientation. But the positions may have become too starkly delineated in order for the debate to reach any breakthrough: a seemingly unbridgeable gap yawns between the stances of ‘technology with (...) a small “t”’ and ‘Technology with a capital “T.”' Is there any way to reorient the debate? In this paper I propose to do so by considering whether there would be some way of arriving from one end of the spectrum to the other—crossing the gap. Exploring the purported wasteland in between “technology” and “Technology” by way of object-oriented ontology (OOO)—Harman, Morton—we can find it actually filled with countless gaps, adhering to every thing. Following the radical insights of OOO, we’d have to attest to a ‘thing-transcendentality.’ The ‘gap,’ then, that seemed so threatening and all-encompassing, becomes smeared out, levelled down to a multiplicity of perspectives. And this casts the debate, with its purported strict tension between ‘empirical’ and ‘transcendental’ positions, in fresh terms, opening up new ways for studying how the two interrelate. (shrink)

The rise of authoritarian and nationalist forces is currently accompanied by a change in the way public opinion is formed and in the culture of debate, a phenomenon that has been described as a crisis of facticity. There is an urgent need to clarify the (factual) foundations and benchmarks for democratic negotiation, even if lies are nothing new in politics. The article analyses this shift and discusses to what extent the liberal problematization of post-factual politics is becoming a way of (...) coping with the neoliberal crisis of hegemony. Finally, it seeks to illuminate what these developments mean for those strands of critical social science dedicated to exploring the connection between truth and power and deconstructing truth claims.

Contrastivism is the claim that the knowledge relation is ternary, it relates three relata: a subject, a proposition, and a class of contrastive propositions. The present paper is a discussion of Jonathan Schaffer’s arguments in favour of contrastivism. The case is made that these are unconvincing: the traditional binary account of knowledge can handle the phenomena that ternarity is claimed to handle in a superior way.

Dov Gabbay is a prolific logician just by himself. But beyond that, he is quite good at making other people investigate the many further things he cares about. As a result, King's College London has become a powerful attractor in our field worldwide. Thus, it is a great pleasure to be an organizer for one of its flagship events: the Augustus de Morgan Workshop of 2005. Benedikt Loewe and I proposed the topic of 'interactive logic' for this occasion, with an (...) emphasis on social software – the logical analysis and design of social procedures – and on games, arguably the formal interactive setting par excellence. This choice reflects current research interests in our logic community at ILLC Amsterdam and beyond. In this broad area of interfaces between logic, computer science, and game theory, this paper is my own attempt at playing Dov. I am, perhaps not telling, but at least asking other people to find out for me what I myself cannot. (shrink)

There are a number of dimensions to the realism-nominalism controversy. The topics of debate comprise: necessary connections and causality, dispositions and counterfactuals, space and time, the existence of abstract entities and mathematical objects, the existence of the theoretical entities of science. On all these except the last, Sellars takes a non-realist line: and on all these except the last, I agree with him to the extent that I presently have an opinion on them. But Sellars is a scientific realist, encapsulating (...) this realism in the dictum: “to have good reason for holding a theory is ipso facto to have good reason for holding that the entities postulated by the theory exist”.

In [11] it is shown how propositional dynamic logic (PDL) can be interpreted as a logic of belief revision that extends the logic of communication and change (LCC) given in [7]. This new version of epistemic/doxastic PDL does not impose any constraints on the basic relations and because of this it does not suffer from the drawback of LCC that these constraints may get lost under updates that are admitted by the system. Here, we will impose one constraint, namely that (...) the agent’s plausibility relations are linked. Linkedness is a natural extension of local connectedness to the multi-agent case and it assures that we know the agent’s preferences between all relevant alternatives. Since the belief updates that are used in [11] may not preserve linkedness, we limit ourselves to a particular kind of belief change that does preserve it. Our framework has obvious connections to coalition logic [17] and social choice theory [19]. We show how we can use it to model consensus seeking in plenary Dutch meetings. In Dutch meetings, a belief update is done for all agents in the meeting if a majority beliefs the proposition that is under discussion. A special case of these meetings is judgement aggregation, and we apply our framework to the discursive dilemma in this field [15]. (shrink)

International political, social, economic and religious developments influence how local communities operate. The South African church society is influenced by such developments taking place globally and which clearly influence how local churches function. This article explores the role of the contemporary church as a ‘reformation agency’ in enhancing a socially transformative agenda in South Africa. A qualitative research approach – an interpretative phenomenology design – was employed to negotiate a shared understanding through conversation and intersubjective meaning-making with church ministers, with (...) the primary focus being their subjective experience of the changing role of the church in enhancing a transformative agenda in a South African context. A purposive sampling consisted of local church leaders who participated in the face-to-face and telephonic semi-structured interviews to achieve the purpose of the study. The findings clearly show that deliberate and intentional actions by churches allow them to become a voice for the marginalised, to create spaces for searching for excellence and to increase the quality of servant leadership, all as vehicles for transforming church society. Furthermore, servant leadership is a social phenomenon, a philosophy-in-practice aimed at leading by example to achieve a common goal. To accomplish this, church ministers are required to spearhead the challenge as a prerequisite to creating ‘lived experienced’ opportunities for members as an inward-outward spiritual journey. Finally, church leaders believed that transformation is a secular dimension, but that it can also be aligned towards God’s redemption plan and enhancing a socially just transformation agenda. Ultimately, this study proposed several recommendations to allow the local church to be relevant in practicing and promoting stronger unity and reconciliation amongst all churches nationally and globally.

Although the concept of corporate social performance (CSP) has become more clearly specified in recent years, an analysis of CSP from the perspective of one particular stakeholder group has been largely ignored in this research: employees. It is proposed that employees merit specific attention with regard to assessments of corporate social performance. In this paper, a model for evaluating and measuring CSP at the employee level is proposed, and implications for evaluating contemporary employment policies and practices are offered. An iterative (...) process for systematically including normative content in the CSP model across stakeholder groups is also offered. (shrink)

ABSTRACTIn this paper I offer an interventionist perspective on the explanatory structure and explanatory power of dynamical models in cognitive science: I argue that some “pure” dynamical models – ones that do not refer to mechanisms at all – in cognitive science are “contextualized causal models” and that this explanatory structure gives such models genuine explanatory power. I contrast this view with several other perspectives on the explanatory power of “pure” dynamical models. One of the main results is that dynamical (...) models need not refer to underlying mechanisms in order to be explanatory. I defend and illustrate this position in terms of dynamical models of the A-not-B error in developmental psychology as elaborated by Thelen and colleagues, and dynamical models of unintentional interpersonal coordination developed by Richardson and colleagues.

Non-consequentialist libertarianism usually revolves around the claim that there are only “negative,” not “positive,” rights. Libertarian nega- tive-rights theories are so patently problematic, though, that it seems that there is a more fundamental notion at work. Some libertarians think this basic idea is freedom or liberty; others, that it is self-ownership. Neither approach is satis- factory.

Transition systems can be viewed either as process diagrams or as Kripke structures. The rst perspective is that of process theory, the second that of modal logic. This paper shows how various formalisms of modal logic can be brought to bear on processes. Notions of bisimulation can not only be motivated by operations on transition systems, but they can also be suggested by investigations of modal formalisms. To show that the equational view of processes from process algebra is closely related (...) to modal logic, we consider various ways of looking at the relation between the calculus of basic process algebra and propositional dynamic logic. More concretely, the paper contains preservation results for various bisimulation notions, a result on the expressive power of propositional dynamic logic, and a de nition of bisimulation which is the proper notion of invariance for concurrent propositional dynamic logic.

Galileo proposed what has been called a proto-inertial principle, according to which a body un horizontal motion will conserve its motion. This statement is only true in counterfactual circumstances where no impediments are present. This paper analyzes how Galileo could have been justified in ascribing definite properties to this idealized motion. This analysis is then used to better understand the relation of Galileo’s proto-inertial principle to the classical inertial principle.

In 2003, Peratt demonstrated that rock art images worldwide bear a remarkable similarity to high-energy plasma discharge formations. In later papers, Peratt located the plasma discharge column in which all of these would have occurred at the Earth’s South Pole. This article accepts the relation between the rock art images and the plasma formations, but concludes that the geometry of the reconstruction is incompatible with the global occurrence of the rock art images. As a corollary, the finer details of the (...) reconstructed column must also be called into question. In particular, the reconstruction of the top cusp, the two upper plasmoids, and the filamentary sheath in a single column at the South Pole cannot be reliably deduced from the data as presented by Peratt. All evidence points to a worldwide distribution of the phenomena. (shrink)

Rationalism offers an account of moral properties as a subset of the properties which serve to rationalize right actions, and these properties are fit to be the referents of our moral terms. That fitness can be exploited in constructing an externalist theory of reference determination for these terms. The resulting externalist theory draws support from standard responses to Moral Twin-Earth scenarios. The relevance of these responses to moral semantics has recently beenvigorously challenged by Dowell and by Schroeter and Schroeter. The (...) social character of meaning relations, which can explain the openness of questions about an analysis, may thereby also make Twin-Earth judgements beside the point. But the resources available to translators go beyond semantic competence and it is these resources that nonetheless make the Moral Twin-Earth responses relevant. (shrink)

This collection of essays addresses recent and historical changes in the ways in which listening has been conceived as a cultural agency and act. It argues that listening, by emancipating from an essentially implied, passive-receiving, and subjected position, has become an explicit factor in culture and the object of proactive collective and individual politics.

Marie van Loon | : In this paper, I argue that Alfred Mele’s conception of self-deception is such that it always fulfils the reasons-responsiveness condition for doxastic responsibility. This is because self-deceptive mechanisms of belief formation are such that the kind of beliefs they bring about are the kind of beliefs that fulfil the criteria for doxastic responsibility from epistemic reasons responsiveness. I explain why in this paper. Mele describes the relation of the subject to the evidence as a biased (...) relation. The subject does not simply believe on the basis of evidence, but on the basis of manipulated evidence. Mele puts forward four ways in which the subject does this. The subject could misinterpret positively or negatively, selectively focus, or gather evidence. Through these ways of manipulation, the evidence is framed such that the final product constitutes evidence on the basis of which the subject may believe a proposition that fits that subject’s desire that P. Whichever form of manipulation the subject uses, the evidence against P must be neutralized in one way or another. Successful neutralization of the evidence requires the ability to recognize what the evidence supports and the ability to react to it. These abilities consist precisely in the two parts of the reasons-responsiveness condition, reasons receptivity and reasons reactivity. In that sense, self-deceptive beliefs always fulfil the reasons-responsiveness condition for doxastic responsibility. However, given that reasons responsiveness is only a necessary condition for doxastic responsibility, this does not mean that self-deceived subjects are always responsible for their belief. | : Dans cet article, je soutiens que la conception d’auto-illusion chez Alfred Mele remplit toujours l’une des conditions de la responsabilité doxastique, à savoir la « sensibilité aux raisons ». Il en est ainsi car les mécanismes d’auto-illusion dans la formation de croyances produisent des types de croyances qui remplissent les critères pour la responsabilité doxastique quant à la sensibilité aux raisons épistémiques. J’explique pourquoi dans cet article. Mele décrit la relation du sujet à la preuve comme biaisée. Le sujet ne croit pas seulement sur la base de preuves, mais de preuves manipulées. Mele avance quatre façons qu’a le sujet de faire ceci. Le sujet peut mal interpréter positivement ou négativement, focaliser de façon sélective, ou accumuler des preuves. Par ces formes de manipulations, la preuve est formulée de sorte qu’elle produise un fondement pour la croyance en une proposition qui s’accorde avec le désir du sujet que P. Peu importe la forme de manipulation qu’emploie le sujet, la preuve contre P doit être neutralisée d’une façon ou d’une autre. Une neutralisation réussie de la preuve requiert la capacité de reconnaître ce que soutient la preuve et la capacité d’y réagir. Ces capacités consistent précisément en ces deux parties de la condition de la sensibilité aux raisons, soit la réceptivité et la réactivité aux raisons. En ce sens, les croyances d’auto-illusion remplissent toujours la condition de la sensibilité aux raisons pour la responsabilité doxastique. Toutefois, étant donné que la sensibilité aux raisons n’est une condition nécessaire que pour la responsabilité doxastique, cela ne veut pas dire que les sujets souffrant d’auto-illusion sont toujours responsables de leurs croyances.
