This book examines the birth of the scientific understanding of motion. It investigates which logical tools and methodological principles had to be in place to give a consistent account of motion, and which mathematical notions were introduced to gain control over conceptual problems of motion. It shows how the idea of motion raised two fundamental problems in the 5th and 4th century BCE: bringing together being and non-being, and bringing together time and space. The first problem leads to the exclusion (...) of motion from the realm of rational investigation in Parmenides, the second to Zeno's paradoxes of motion. Methodological and logical developments reacting to these puzzles are shown to be present implicitly in the atomists, and explicitly in Plato who also employs mathematical structures to make motion intelligible. With Aristotle we finally see the first outline of the fundamental framework with which we conceptualise motion today. (shrink)

This paper has two main goals: first, it reconstructs Aristotle’s account of measurement in his Metaphysics and shows how it connects to modern notions of measurement. Second, it demonstrates that Aristotle’s notion of measurement only works for simple measures, but leads him into a dilemma once it comes to measuring complex phenomena, like mo-tion, where two or more different aspects, such as time and space, have to be taken into account. This is shown with the help of Aristotle’s reaction to (...) one of the problems Zeno’s dichotomy paradox raises: Aristotle implicitly employs a complex measure of motion when solving this problem, while he explicitly characterizes the measure of motion as a simple measure in his Physics.

In this paper, I want to show that continuity is of crucial philosophical significance in Parmenides, who is the first thinker in the West to use the notion of continuity in a philosophically interesting and systematic way, and what being continuous (suneches) means for him. I look in some detail at the three passages in fragment 8 of Parmenides’ poem that are central for Parmenides’ notion of being suneches and discuss whether being suneches refers to something being temporally uninterrupted, spatially (...) connected, or ontologically holding together. An analysis of these three passages shows that suneches for Parmenides implies complete homogeneity and indivisibility. This analysis is also the basis for showing that suneches is conceptualized very differently in Parmenides’ poem and Aristotle’s Physics because of different starting points and different understandings of what we would call the principle of sufficient reason.

This paper aims to show that—and how—Plato’s notion of the receptacle in the Timaeus provides the conditions for developing a mathematical as well as a physical space without itself being space. In response to the debate whether Plato’s receptacle is a conception of space or of matter, I suggest employing criteria from topology and the theory of metric spaces as the most basic ones available. I show that the receptacle fulfils its main task–allowing the elements qua images of the Forms (...) to exist as sensible things by being that in which the elements appear, change and move–in virtue of being pure continuity. All further qualifications required for a full notion of space are derived solely from the content of the receptacle. (shrink)

Zeno’s Moving Rows paradox is the only paradox among his four paradoxes of motion that is usually skipped over as being of no philosophical interest. This paper aims to give a new diagnosis of the Moving Rows paradox, a diagnosis that allows us to see it as raising a philosophically interesting problem concerning the relationship of time, space, and motion. It shows the consequences of confusing time’s dependence on the space covered in a motion with time’s dependence on the motion (...) performed. I argue that, to date, the paradox has not been given the correct analysis – usually being reconstructed either as a mere oversight, or as some confusion about the relativity of motion, or as a very different atomistic paradox.

In this paper I show that one of the most fruitful ways of employing paradoxes has been as a philosophical method that forces us to reconsider basic assumptions. After a brief discussion of recent understandings of the notion of paradoxes, I show that Zeno of Elea was the inventor of paradoxes in this sense, against the background of Heraclitus’ and Parmenides’ way of argumentation: in contrast to Heraclitus, Zeno’s paradoxes do not ask us to embrace a paradoxical reality; and in (...) contrast to Parmenides, Zeno shows common assumptions to be internally problematic, not just in light of Eleatic positions.

This paper argues that the problem of how to act in the face of radical contingency is of central importance in Musil’s novel and intimately connected to what Musil calls the sense of possibility. There is a variety of different strategies by which individuals, and the state of Kakania as a whole, deal with contingency, and they all involve a claim to a kind of grounding or necessity; for example, the Parallel Campaign is one big attempt to ground Kakania in (...) what can be perceived as a form of metaphysical necessity. With the figure of Ulrich, Musil radicalizes the problem by showing the consequences of viewing even the relationship one has to one’s own self as contingent – the ultimate outcome of which is self-alienation.

While Aristotle provides the crucial testimonies for the paradoxes of motion, topos, and the falling millet seed, surprisingly he shows almost no interest in the paradoxes of plurality. For Plato, by contrast, the plurality paradoxes seem to be the central paradoxes of Zeno and Simplicius is our primary source for those. This paper investigates why the plurality paradoxes are not examined by Aristotle and argues that a close look at the context in which Aristotle discusses Zeno holds the answer to (...) this question.

This book explores a distinctive feature of ancient philosophy: the close relation between ancient ethics and the study of the natural world. Human beings are in some sense part of the natural world, and they live their lives within a larger cosmos, but their actions are governed by norms whose relation to the natural world is up for debate. The essays in this volume, written by leading specialists in ancient philosophy, discuss how these facts about our relation to the world (...) bear both upon ancient accounts of human goodness and also upon ancient accounts of the natural world itself. The volume includes discussion not only of Plato and Aristotle, but also of earlier and later thinkers, with an essay on the Presocratics and two essays that discuss later Epicurean, Stoic, and Neoplatonist philosophers.

This paper argues that processes in the sensible realm can be in accord with reason in the Timaeus, since rationality is understood here as being based on regularity, which is conferred onto processes by time. Plato uses two different temporal structures in the Timaeus, associated with the contrast there drawn between Greek and Egyptian approaches to history. The linear order of before and after marks natural processes as rational and underlies the Greek treatment of history. By contrast, a bidirectional temporal (...) structure is the basis for the Egyptian approach to historical processes: present actions are not only determined by preceding ones in the past, but can also be influenced by the future (plans, aims). This latter temporal structure is shown to be necessary for learning from history, which makes human actions more regular. (shrink)

The paper demonstrates that Parmenides’ monism is a logical consequence of his criteria for philosophy, in conjunction with the logical operators he uses, and their holistic connection. Parmenides, I argue, is the first philosopher to set out explicit criteria for philosophy, establishing as criterion not only consistency, but also what I call rational admissibility, the requirement when giving an account of something that the account be based on rational analysis and can withstand rational scrutiny. I give a detailed account of (...) the logical operators Parmenides uses in his argument and of the way in which his notion of being is tailored to fit both them and his criteria for philoso-phy.

Whatever our metaphysics of time, today we usually work with the assumption that we have one unified temporal framework, which allows for situating all events, processes, and happenings in the sense that we can put them all in a temporal relation to each other; they are all either before, after, or simultaneous with each other. In this paper, I show that for the early Greeks, by contrast, the very idea of such a unified notion of time would be foreign; instead, (...) they assume different temporal (and not necessarily comparable) struc-tures belonging to different events. And I show what effect this lack has on the quality of temporal experiences – it means that different temporal experiences are thus seen as expe-riences of genuinely different kinds. (shrink)

This is part of a two-paper project to show in detail in ways that have not been attempted before that, in the Symposium, Plato uses the language and metaphors of the Eleusinian Mysteries as a template for the ascent to the Form of Beauty; and also to explain why he might have chosen to do so. The standard accounts of the Eleusinian Mysteries come from sources that have themselves been influenced by Plato and hence are unsuitable to demonstrating the extent (...) of his exploitation of the Mysteries. This first paper offers a reconstruction of what can be known about the Eleusian Mysteries with the help of Pre-Platonic sources, by looking at material culture, archaeological remains, and pre-Platonic literature.

What did the early Greek philosophers think about animals and their lives? How did they view plants? And, ultimately, what type of relationship did they envisage between all sorts of living beings? On these topics there is evidence of a prolonged investigation by several Presocratics. However, scholarship has paid little attention to these issues and to the surprisingly "modern" development they received in Presocratics' doctrines. This book fills this lacuna through a detailed (and largely unprecedented) analysis of the extant evidence. (...) The volume includes also the first extensive collection of the ancient sources pertaining to living beings and life in early Greek philosophy, organized chronologically and thematically. (shrink)

A large part of the difficulty of writing "conceptual history"—to borrow a term from Reviel Netz —is that once an illuminating new conceptual framework is articulated, it begins to seem self-evident and commonsensical to later thinkers. The historian's task of problematizing the obvious, and showing us the moves by which commonsense came to be created historically, is an arduous and challenging one, requiring resources of imagination, patience, and attention to detail. Sattler displays all those qualities in this dense and (...) demanding study, and a review needs to begin by acknowledging the sheer... (shrink)

Free will has been the object of debate in the context of addiction given that addiction could compromise an individual’s ability to choose freely between alternative courses of action. Proponents of the brain-disease model of addiction have argued that a neuroscience perspective on addiction reduces the attribution of free will because it relocates the cause of the disorder to the brain rather than to the person, thereby diminishing the blame attributed to the person with an addiction. Others have worried that (...) such displacement of free will attribution would make the person with a drug addiction less responsible. Using the paradigmatic literature on the seductive allure of neuroscience explanations, we tested whether neuroscience information diminishes attributions of free will in the context of addiction and whether respondent characteristics influence these attributions and modulate the effect of neuroscience information. We performed a large-scale, web-based experiment with 2,378 German participants to explore how attributions of free will in the context of addiction to either alcohol or cocaine are affected by: (1) a text with a neurobiological explanation of addiction, (2) a neuroimage showing effects of addiction on the brain, and (3) a combination of a text and a neuroimage, in comparison to a control group that received no information. Belief in free will was measured using the FAD-Plus scale and was, subsequent to factor analysis, separated into two factors: responsibility and volition. The investigated respondent characteristics included gender, age, education, self-reported knowledge of neuroscience, substance-use disorder (SUD), and having a friend with SUD. We found that attributions of volition (in the cocaine-subsample) were reduced in the text and neuroimage-treatment compared to the control group. However, respondent characteristics such as education and self-reported knowledge of neuroscience were associated with lower attributions of responsibility for both substances, and education was associated with lower attribution of volition for the alcohol sub-sample. Interaction analyses showed that knowledge of neuroscience was found to generally decrease attribution of responsibility. Further research on attribution of free will should consider the effects of context and respondent characteristics, which appeared surprisingly larger than those induced by experimental treatments.

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

We investigated the acceptability and frequency of the use of cognitive enhancement (CE) drugs and three different types of academic misconduct (plagiarism, cheating in exams, and falsifying/fabricating data). Data from a web-based survey among German university students were used. Moral acceptability was relatively low for CE drug use and moderate for academic misconduct, while the correlation of their respective acceptability was moderately weak. Prevalence of CE drug use was lower than for academic misconduct and (very) lightly correlated with the prevalence (...) of plagiarism and fabrication/falsification. Acceptability of the investigated behaviors was associated with higher prevalence rates of each behavior. (shrink)

Ulrich Beck's best selling Risk Society established risk on the sociological agenda. It brought together a wide range of issues centering on environmental, health and personal risk, provided a rallying ground for researchers and activists in a variety of social movements and acted as a reference point for state and local policies in risk management. The Risk Society and Beyond charts the progress of Beck's ideas and traces their evolution. It demonstrates why the issues raised by Beck reverberate widely throughout (...) social theory and covers the new risks that Beck did not foresee, associated with the emergence of new technologies, genetic and cybernetic. The book is unique because it offers both an introduction to the main arguments in Risk Society and develops a range of critical discussions of aspects of this and other works of Beck. (shrink)

Szabó follows Heim in viewing familiarity, rather than uniqueness, as the essence of the definite article, but attempts to derive both familiarity and uniqueness implications pragmatically, assigning a single semantic interpretation to both the definite and indefinite articles. I argue that if there is no semantic distinction between the articles, then there is no way to derive these differences between them pragmatically.

Description logics are a family of knowledge representation formalisms that are descended from semantic networks and frames via the system Kl-one. During the last decade, it has been shown that the important reasoning problems (like subsumption and satisfiability) in a great variety of description logics can be decided using tableau-like algorithms. This is not very surprising since description logics have turned out to be closely related to propositional modal logics and logics of programs (such as propositional dynamic logic), for which (...) tableau procedures have been quite successful.Nevertheless, due to different underlying institutions and applications, most description logics differ significantly from run-of-the-mill modal and program logics. Consequently, the research on tableau algorithms in description logics led to new techniques and results, which are, however, also of interest for modal logicians. In this article, we will focus on three features that play an important rôle in description logics (number restrictions, terminological axioms, and role constructors), and show how they can be taken into account by tableau algorithms.

Cette introduction explique la perception, reconnue par Husserl sous le titre de "donation par esquisses". Il s'agit d'opérer une réduction radicale qui va de la critique du néant au monde comme a priori de tout apparaître. A ce monde correspond un sujet dont le sens d'être fait problème puisqu'il est à la fois un moment du monde et en rapport avec la totalité comme telle.

L'oeuvre de Merleau-Ponty est tout entiere commandee par le souci de mettre rigoureusement en oeuvre le mot d'ordre husserlien de retour aux choses memes, ce qui exige, conformement au geste amorce par Husserl dans la Krisis, de reconnaitre l'oeuvre de l'idealisation -c'est-a-dire de l'objectivation- la meme ou elle se fait oublier, afin de la neutraliser. A l'instar de Bergson, pour qui la tache de la philosophie etait d'aller chercher l'experience au-dessus du tournant ou, s'inflechissant dans le sens de l'utilite, elle (...) devient proprement l'experience humaine, pour Merleau-Ponty, la tache de la pensee est de se situer a ce tournant ou l'experience s'accomplit et se voile a la fois dans des productions ou elle se fait proprement humaine, de definir un sens de l'Etre anterieur a la bifurcation du preobjectif et de l'oeuvre idealisante. Le but des recherches est de tenter de clarifier la nature exacte du tournant de l'experience ainsi que le projet phenomenologique merleau-pontien. (shrink)

Stimulant drugs, transcranial magnetic stimulation, brain-computer interfaces, and even genetic modifications are all discussed as forms of potential cognitive enhancement. Cognitive enhancement can be conceived as a benefit-seeking strategy used by healthy individuals to enhance cognitive abilities such as learning, memory, attention, or vigilance. This phenomenon is hotly debated in the public, professional, and scientific literature. Many of the statements favoring cognitive enhancement (e.g., related to greater productivity and autonomy) or opposing it (e.g., related to health-risks and social expectations) rely (...) on claims about human welfare and human flourishing. But with real-world evidence from the social and psychological sciences often missing to support (or invalidate) these claims, the debate about cognitive enhancement is stalled. In this paper, we describe a set of crucial debated questions about psychological and social aspects of cognitive enhancement (e.g., intrinsic motivation, well-being) and explain why they are of fundamental importance to address in the cognitive enhancement debate and in future research. We propose studies targeting social and psychological outcomes associated with cognitive enhancers (e.g., stigmatization, burnout, mental well-being, work motivation). We also voice a call for scientific evidence, inclusive of but not limited to biological health outcomes, to thoroughly assess the impact of enhancement. This evidence is needed to engage in empirically informed policymaking, as well as to promote the mental and physical health of users and non-users of enhancement. (shrink)

This book presents the most important problems of reference and considers their solution. It presupposes no technical knowledge, presents analyses from first principles, illustrates every stage with examples, and is written with verve and clarity. This is the ideal introduction to reference for students of linguistics and philosophy of language.

Pathological morphogenesis on leaves of Fraxinus ornus (ash) and Solanum lycopersicum (tomato) under the influence of mites (Aceria fraxinivora and Eriophyes cladophthirus respectively) leads to a range of structures whose morphology and development cannot be reduced to the classical categories of plant morphology, but present a heterogeneous continuum which links fundamental structural categories. These findings support the pyramid model of plant construction.

Neste artigo, concentro-me sobre quatro variedades possíveis de ausência da vergonha. Minha esperança é a de que a reflexão sobre essas variedades possa, de alguma maneira, nos dar uma imagem mais completa acerca do papel que a vergonha desempenha sobre nosso caráter moral e nas discussões a respeito da atrocidade. Observo que a vergonha que emerge de uma exposição à atrocidade pode em parte constituir aquilo que nos leva a identificar oevento como atroz. Prossigo então argumentando que quando a vergonha (...) está ausente, esta ausência pode servir para nos cegar para a atrocidade que está à nossa frente, e que é nossa tarefa tentar evitar. Sentir vergonha faz parte de ver a atrocidade pelo que ela é de uma maneira apropriada emocionalmente engajada. Ela é, portanto, uma parte vital de ser humano, e sua ausência em certos casos é uma insuficiência demasiadamente humana de humanidade. (shrink)

We describe BDD-based decision procedures for the modal logic K. Our approach is inspired by the automata-theoretic approach, but we avoid explicit automata construction. Instead, we compute certain fixpoints of a set of types — which can be viewed as an on-the-fly emptiness of the automaton. We use BDDs to represent and manipulate such type sets, and investigate different kinds of representations as well as a “level-based” representation scheme. The latter turns out to speed up construction and reduce memory consumption (...) considerably. We also study the effect of formula simplification on our decision procedures. To prove the viability of our approach, we compare our approach with a representative selection of other approaches, including a translation of K to QBF. Our results indicate that the BDD-based approach dominates for modally heavy formulae, while search-based approaches dominate for propositionally heavy formulae. (shrink)

This book considers the context of the colonial policies of Britain, Locke's contribution to them, and the importance of these ideas in his theory of property. It also reconsiders the debate about John Locke's influence in America. The book argues that Locke's theory of property must be understood in connection with the philosopher's political concerns, as part of his endeavour to justify the colonialist policies of Lord Shaftesbury's cabinet, with which he was personally associated. The author maintains that traditional scholarship (...) has failed to do justice to Locke by ignoring the implications of contemporary British imperial policy for the interpretation of his political thought.

This paper investigates Slovak migrants’ use of new media to build social capital. It draws on data from a pilot study with 36 Slovaks living in the UK, and on content analysis of the main Facebook page for Czechs and Slovaks in the UK. The data suggest that Facebook is used for sharing emotions rather than to build a community and share practical information. While Facebook and Skype are used to maintain preexisting strong ties in the country of origin, face-to-face (...) contact and mobile phones are used to maintain ties within the UK. However, social media do not seem to facilitate the formation of weak ties prior to migration, with face-to-face contact being dominant upon arrival. Transnational migration experience forms a separate dimension within the participants’ identity, independent from social capital. The data are discussed in relation to findings from previous studies about Slovak migrants in the Republic of Ireland. (shrink)
