This paper studies Sentence 16 of Porphyry's Pathways to the Intelligible . It is argued that it should be understood against the background of Plotinus' discussions of the similes of the waxen block and the aviary from Plato's Theaetetus . The first part of the paper concentrates on Plotinus' reception of these similes. In the second part of the paper Plotinus' discussions of the two similes are used to shed light on Sentence 16, in particular on the term προχείρισις. Furthermore (...) it is argued that Porphyry does not reject Plotinus' claim that, pace Aristotle, intellection does not require imaging. (shrink)
In this paper we investigate Accardi's claim that the "quantum paradoxes" have their roots in probability theory and that, in particular, they can be evaded by giving up Bayes' rule, concerning the relation between composite and conditional probabilities. We reach the conclusion that, although it may be possible to give up Bayes' rule and define conditional probabilities differently, this contributes nothing to solving the philosophical problems which surround quantum mechanics.
In this article we argue that discourse structure constrains the set ofpossible constituents in a discourse that can provide the relevantcontext for structuring information in a target sentence, whileinformation structure critically constrains discourse structureambiguity. For the speaker, the discourse structure provides a set of possible contexts for continuation while information structure assignment is independent of discourse structure. For the hearer, the information structure of a sentence together with discourse structure instructs dynamic semantics how rhematic (...) information should be used to update the meaning representation of the discourse (Polanyi and van den Berg, 1996).

Van den Belt recently examined the notion that synthetic biology and the creation of ‘artificial’ organisms are examples of scientists ‘playing God’. Here I respond to some of the issues he raises, including some of his comments on my previous discussions of the value of the term ‘life’ as a scientific concept.
The present discussion of sociobiological approaches to ethnic nepotism takes Pierre van den Berghe ʼs theory as a starting point. Two points, which have not been addressed in former analyses, are considered to be of particular importance. It is argued that the behavioral mechanism of ethnic nepotism—as understood by van den Berghe—cannot explain ethnic boundaries and attitudes. In addition, I show that van den Bergheʼs central premise concerning ethnic nepotism is in contradiction to Hamiltonʼs formula, the essential principle of kin (...) selection theory. It is further discussed how other approaches that make reference to ethnic nepotism are related to van den Bergheʼs account and its problems. I conclude with remarks on the evolutionary explanation of ethnic phenomena. (shrink)
We revisit the characterization of the Shapley value by van den Brink (Int J Game Theory, 2001, 30:309–319) via efficiency, the Null player axiom, and some fairness axiom. In particular, we show that this characterization also works within certain classes of TU games, including the classes of superadditive and of convex games. Further, we advocate some differential version of the marginality axiom (Young, Int J Game Theory, 1985, 14: 65–72), which turns out to be equivalent to the van den Brink (...) fairness axiom on large classes of games.

I define serendipity as the art of making an unsought finding. And I propose an overview of my collection of serendipities, the largest yet assembled, chiefly in science and technology, but also in art, by giving a list of ‘serendipity patterns’. Although my list of ‘patterns’ is just a list and not a classification, it serves to introduce a new and possibly stimulating perspective on the old subject of serendipity. Knowledge of these ‘serendipity patterns’ might help in expecting also the (...) unexpected and in finding also the unsought. * I acknowledge A. D. de Groot, R. C. M. Noordam, B. P. van Heusden, T. Pinkster, C. J. van den Berg, T. A. F. Kuipers, A. Wegener Sleeswijk and my referee for their suggestions and I dedicate this article to T. A. van Kooten. Cases and studies of serendipidy are welcome. À propos: a travelling serendipity exhibition is available, also for ‘new democracies’: ‘Freedom of opportunity as developed by democracy is the best human reaction to divergent phenomena. We may, in fact, define ‘freedom’ as ‘the opportunity to profit from the unexpected.’ (Langmuir [1956]). (shrink)
Kant is well known for his restrictive conception of proper science. In the present paper I will try to explain why Kant adopted this conception. I will identify three core conditions which Kant thinks a proper science must satisfy: systematicity, objective grounding, and apodictic certainty. These conditions conform to conditions codified in the Classical Model of Science. Kant’s infamous claim that any proper natural science must be mathematical should be understood on the basis of these conditions. In order to substantiate (...) this reading, I will show that only in this way it can be explained why Kant thought (1) that mathematics has a particular foundational function with respect to the natural sciences and (2) as such secures their scientific status.

The paper argues that two distinct and independent notions of plurality are involved in natural language anaphora and quantification: plural reference (the usual non-atomic individuals) and plural discourse reference, i.e., reference to a quantificational dependency between sets of objects (e.g., atomic/non-atomic individuals) that is established and subsequently elaborated upon in discourse. Following van den Berg (PhD dissertation, University of Amsterdam, 1996), plural discourse reference is modeled as plural information states (i.e., as sets of variable assignments) in a new dynamic (...) system couched in classical type logic that extends Compositional DRT (Muskens, Linguistics and Philosophy, 19, 143–186, 1996). Given the underlying type logic, compositionality at sub-clausal level follows automatically and standard techniques from Montague semantics become available. The idea that plural info states are semantically necessary (in addition to non-atomic individuals) is motivated by relative-clause donkey sentences with multiple instances of singular donkey anaphora that have mixed (weak and strong) readings. At the same time, allowing for non-atomic individuals in addition to plural info states enables us to capture the intuitive parallels between singular and plural (donkey) anaphora, while deriving the incompatibility between singular (donkey) anaphora and collective predicates. The system also accounts for empirically unrelated phenomena, e.g., the uniqueness effects associated with singular (donkey) anaphora discussed in Kadmon (Linguistics and Philosophy, 13, 273–324, 1990) and Heim (Linguistics and Philosophy, 13, 131–177, 1990) among others.

The paper proposes an account of the contrast (noticed in Karttunen 1976) between the interpretations of the following two discourses: Harvey courts a girl at every convention. {She is very pretty. vs. She always comes to the banquet with him.}. The initial sentence is ambiguous between two quantifier scopings, but the first discourse as a whole allows only for the wide-scope indefinite reading, while the second allows for both. This cross-sentential interaction between quantifier scope and anaphora is captured by means (...) of a new dynamic system couched in classical type logic, which extends Compositional DRT (Muskens 1996) with plural information states (modeled, following van den Berg 1996, as sets of variable assignments). Given the underlying type logic, compositionality at sub-clausal level follows automatically and standard techniques from Montague semantics become available. The paper also shows that modal subordination (A wolf might come in. It would eat Harvey first) can be analyzed in a parallel way, i.e. the system captures the anaphoric and quantificational parallels between the individual and modal domains argued for in Stone (1999) (among others). In the process, we see that modal / individual-level quantifiers enter anaphoric connections as a matter of course, usually functioning simultaneously as both indefinites and pronouns. (shrink)
This article focuses on maternal-fetal surgery (MFS) and on the concept of clinical equipoise that is a widely accepted requirement for conducting randomized controlled trials (RCT). There are at least three reasons why equipoise is unsuitable for MFS. First, the concept is based on a misconception about the nature of clinical research and the status of research subjects. Second, given that it is not clear who the research subject/s in MFS is/are, if clinical equipoise is to be used as a (...) criterion to test the ethical appropriateness of RCT, its meaning should be unambiguous. Third, because of the multidisciplinary character of MFS, it is not clear who should be in equipoise. As a result, we lack an adequate criterion for the ethical review of MFS protocols. In our account, which is based on Chervenak and McCullough's seminal work in the field of obstetric ethics, equipoise is abandoned. and RCT involving MFS can be ethically initiated when a multidisciplinary ethics review board (ERB), having an evidence-based assessment of the risks involved, is convinced that the value of answering the research hypothesis, for the sake of the health interests of future pregnant women carrying fetuses with certain congenital birth defects, justifies the actual risks research participants might suffer within a set limit of low/manageable.

This article proposes a new social- and moral-psychological understanding of cultural identity, tailored to the mixed multicultural contexts of every major city today. Seeking to protect vulnerable cultural groups, theories of multiculturalism have insufficiently assessed the psychological significance of intercultural social comparison, in identity-formation. While plays of prestige are a fact of life for immigrant and gay minorities, not everyone is equally able to cope with ascribed negative prestige. This is shown in an analysis of reactive attitudes towards negative prestige (...) under contrasting conditions (of rough cultural equality, and in underclass-culture). The idea of prestige-resilience is proposed both as an explanatory concept in the debate on underclass-culture and as a normative concept from which basic moral and ethical thresholds for cultural identity-formation might be deduced. Outcomes are considered relevant for psychological analysis of underclass-formation and for multicultural policy-making, specifically in immigrant states. (shrink)
This study bases itself in the epistemological and methodological development of a broad and interdisciplinary dialogue where various voices in the form of different domains converse in order to establish an integrated whole. The research contributes to the actual corporative question regarding spirituality in the workplace, specifically aimed at the individual in the middle-career phase. This phase is characterised as a re-evaluation period aimed at personal and professional growth. A shift in emphasis to the meaning and sense of work is (...) linked to spiritual intelligence as spirituality can be described and understood as a type of intelligence. The study shows that the middle-career experience provides opportunity for an altered future view. Lifestyle coaching serves as facilitating process and offers guidance in answering existential questions which are included in the spiritual. The probable outcome promises to add meaning as a manifesting component in a dynamic and transforming life strategy. (shrink)
General theoretical aspects are reviewed of models for microbial growth and endogenous metabolism. The focus is on a generic cell model with two components. Growth is represented as the increase of one of these components (the structural scaffolding or 'frame'). A novel feature of the present generic model is the explicit modelling of (partial) metabolic shutdown under conditions where maintenance requirements cannot be met.Two different approaches to mechanistic underpinnings for the classic models are outlined. The first approach is based on (...) a bimolecular reaction between the non-permanent biomass component and the permanent biomass component. The second approach is based on cellular control systems.

A microbial colony needs several essential nutrients in order to grow. Moreover, the colony requires these nutrients in fixed combinations, which are dictated by the chemical composition of its biomass. Unfortunately, ambient availabilities of the various nutrients vary all the time. This poses the question of how microbes can achieve balanced growth.The present solution to this problem is novel in that the allocation of molecular building blocks among assimilatory machineries within the cell is regarded as dynamic. This paper shows that (...) allocation can be adapted so as to achieve balanced growth, nearly regardless of environmental conditions. Moreover, it is shown that a feedback mechanism, which monitors internal stores, is able to achieve this allocation. (shrink)
In this article, I will investigate the ways in which Ambient Intelligence, the technological paradigm of the near future proposed by the European Union and the electronics multinational Philips, will affect the ways in which individuals construct and express their identities. The Ambient Intelligence vision predicts a world in which technologies will deliver personalized services in a proactive (rather than a responsive or interactive) fashion. I argue that this brings about a change in the way we interact with these technologies, (...) which in turn has an effect on the way we construct and express identities in relation to such technologies. In a world of Ambient Intelligence, I will argue in this article, technological artifacts may come to function as ‘reference collectivities’, comparable to human reference groups. Due to their proactivity, their level of autonomy and self-reliance and our personalized interactions with them, these technologies will come to function as ‘others’, rather than as ‘quasi-others’.
