In several accounts of what models are and how they function a specific view dominates. This view contains the following characteristics. First, there is a clear-cut distinction between theories, models and data and secondly, empirical assessment takes place after the model is built. This view in which discovery and justification are disconnected is not in accordance with several practices of mathematical business-cycle model building. What these practices show is that models have to meet implicit criteria of adequacy, such as satisfying (...) theoretical, mathematical and statistical requirements, and be useful for policy. In order to be adequate, models have to integrate enough items to satisfy such criteria. These items include besides theoretical notions, policy views, mathematisations of the cycle and metaphors also empirical data and facts. So, the main thesis of this chapter is that the context of discovery is the successful integration of those items that satisfy the criteria of adequacy. Because certain items are empirical data and facts, justification can be built-in. (shrink)

v. 1. Reflection & mystery -- v. 2. Faith & reality.

The kinds of models discussed in this paper function as measuring instruments. We will concentrate on two necessary steps for measurement: (1) the search of a mathematical representation of the phenomenon; (2) this representation should cover an invariant relationship between the properties of the phenomenon to be measured and observable accociated attributes of a measuring instrument. Therefore, the measuring instrument should function as a nomological machine. However, invariant relationships are not necessarily ceteris paribus regularities, but could also occur when the (...) influence of the environment is negligible. Then we are able to achieve accurate measurements outside the laboratory. (shrink)

This is an agenda-setting exploration of the relationship between green politics and liberal ideology. Ecological problems provide unique challenges for liberal democracies.; This challenge is examined by the author who aims to fill the gap between short-term ecological modernization and the politically infeasible longer term utopian approaches.

Recent discussion of the statistical character of evolutionary theory has centered around two positions: (1) Determinism combined with the claim that the statistical character is eliminable, a subjective interpretation of probability, and instrumentalism; (2) Indeterminism combined with the claim that the statistical character is ineliminable, a propensity interpretation of probability, and realism. I point out some internal problems in these positions and show that the relationship between determinism, eliminability, realism, and the interpretation of probability is more complex than previously assumed (...) in this debate. Furthermore, I take some initial steps towards a more adequate account of the statistical character of evolutionary theory. (shrink)

Recently, there has been an effort to make libertarianism compatible with a redistributive inheritance tax: When the tax is levied, the taxpayer in question is already dead and as such she cannot be a bearer of rights. The state is therefore allowed to redistribute the (value of) the estate according to some distributive principle. I consider (and finally dismiss) four successive arguments, each concluding that the state is allowed to use the estate for redistributive purposes. I show that neither of (...) them is able to reconcile (right-) libertarianism with a redistributive inheritance tax. Instead of trying to square the circle, proponents of such a tax should meet the theoretical essentials of (right-) libertarianism head-on. (shrink)

One of the societal problems in a new influenza pandemic will be how to use the scarce medical resources that are available for prevention and treatment, and what medical, epidemiological and ethical justifications can be given for the choices that have to be made. Many things may become scarce: personal protective equipment, antiviral drugs, hospital beds, mechanical ventilation, vaccination, etc. In this paper I discuss two general ethical principles for priority setting (utility and equity) and explain how these principles will (...) often point in diverging directions. Moreover, each of these principles can be understood in different, again often competing, ways. Notwithstanding these controversies and conflicts, in the context of pandemic response there are at least some points of convergence: several policies can be justified by appeal to different ethical principles and theories. Convergence may be found with respect to a focus on saving the most lives (instead of other aggregative accounts); giving priority antiviral prophylaxis and therapy for life-saving pandemic responders; and, partly depending on epidemiology of the pandemic, to prioritise vaccination of children. Although decision-making about access to intensive care will involve choices with immediate tragic implications, the ethical complexity of these choices is relatively modest (although decisions will not be easy): there are persuasive moral reasons for giving priority to patients who are expected to benefit most within the shortest time. Finally, in the last section I tentatively argue that constraints on people’s freedom, as necessary for an effective public health approach, may support giving somewhat more weight to saving the most lives, than to concerns of equity.

Le 'Journal métaphysique', qui, primitivement, n'était pas destiné à la publication, est constitué par un ensemble de notes philosophiques rédigées au jour le jour. L'évidente différence de style entre les deux parties tient au fait que sous la pression de la guerre la pensée de l'auteur s'est tournée de plus en plus résolument vers le concret, vers l'existentiel, qui a trouvé dans le Journal métaphysique une des premières expressions qu'il ait revêtues en France. Il ne faut d'ailleurs pas parler de (...) l'existentialisme, mais une thématique de l'existence considérée dans sa spécificité tend à s'y constituer par une réflexion qui se concentre de plus en plus sur le corps propre (par opposition au corps-objet ou instrument), sur la sensation traitée non plus comme message mais comme façon d'être au monde, sur la mémoire, sur la volonté, etc. Des phénomènes métaphysiques tels que la télépathie, la lecture de pensées, etc. sont considérés avec une attention particulière et l'auteur va jusqu'à se demander s'il ne conviendrait pas d'inverser la relation communément pré-supposée entre le psychologique et le métapsychique et si la clef des phénomènes dits normaux ne devrait pas être cherchée dans le supra-normal.

There is a growing interest in understanding how follower reactions towards abusive leadership are shaped by followers’ perceptions and attributions. Our studies add to the understanding of the process happening between different levels of leaders’ abusive behavior (from constructive leadership as control, laissez-faire, mild to strong abusive) and follower reactions. Specifically, we focus on the role of perception of abusive supervision as a mediator and attribution as a moderator of the relationship between leader abusive behavior and follower reactions. Follower reactions (...) are defined in terms of exit, voice, loyalty, and neglect. Two studies using a two point experimental design and vignettes and a cross-sectional field study were conducted. Perception partly mediates the relationship between leader behavior and reactions (Study 1 and 2). Different attributions (intention, control) moderate the relationship between the perception of abusive supervision and reactions in Study 2 and 3. In Study 2, attribution of intentionality of the leader behavior served as a moderator of the relationship between abusive supervision and loyalty, turnover, and voice. Attribution of intentionality reduced the relationship between perception of abusive supervision and reactions. Attribution of intentionality only strengthened negative reactions when milder abusive leadership was perceived. These results were not supported in Study 3. However, in Study 3, attribution to the supervisor’ control served as moderator for loyalty and voice. A stronger relationship between the perception of abusive supervision and reactions emerged for high versus for low attribution to the supervisor. The differences in results between the studies reflect that in Study 1 and 2 abusive behavior was manipulated and in Study 3 the perception of abusive supervision of actual leaders was assessed. Our findings show that avoidance of abusive supervision should be taken seriously and followers’ perception and suffering is not only due to subjective judgment but reflects actual differences in behavior. The relationships are stronger in the field study, because, in practice, abusive behaviors might be more ambiguous. The research presented here can help leaders to better understand their own and the followers’ role in the perception of and reaction to abusive supervision. (shrink)

The Representational Theory of Measurement conceives measurement as establishing homomorphisms from empirical relational structures into numerical relation structures, called models. Models function as measuring instruments by transferring observations of an economic system into quantitative facts about that system. These facts are evaluated by their accuracy. Accuracy is achieved by calibration. For calibration standards are needed. Then two strategies can be distinguished. One aims at estimating the invariant (structural) equations of the system. The other is to use known stable facts about (...) the system to adjust the model parameters. For this latter strategy, the requirement of models as homomorphic mappings is not required anymore.

Les femmes, à l’époque moderne, admettent, en règle générale, la soumission requise par le clergé masculin. Mais il en est qui résistent.

Generally, simulations are carried out to answer specific questions. The assessment of the reliability of an answer depends on the kind of question investigated. The answer to a 'why' question is an explanation. The premises of an explanation have to include invariant relationships, and thus the reliability of such answer depends on whether the domain of invariance of the relevant relationships covers the domain of the question. The answer to a 'how much' question is a measurement. A measurement is reliable (...) when it is an output of a calibrated measuring instrument. (shrink)

Introduction Moral concern for animals is commonly formulated in terms of concern for their welfare. Yet, besides the welfare issue, although highly ...

Due to its emphasis on experiential interests, animal ethics tends to focus on individuals as the sole unit of moral concern. Many issues in animal ethics can be fruitfully analysed in terms of obligations towards individual animals, but some problems require reflection about collective dimensions of animal life in ways that individualist approaches can’t offer. Criticism of the individualist focus in animal ethics is not new; it has been put forward in particular by environmental ethics approaches. However, the latter tend (...) to be so far removed from the concerns of animal ethicists that both groups talk at cross purposes. We think the gap between environmental and animal ethics could be bridged by on the one hand focusing more on the collective dimensions of our concerns with animals - after all, individuals are constituted by the collective of which they are a part - and on the other hand, by showing that moral status can also be attributed to groups in an indirect way, related to the moral status of their individual members. In our paper we explore various ways of conceptualising the moral relevance of collectiveness in animal life. We draw on insights from public health ethics, as this field of inquiry has also developed - at least partly—in response to individualist approaches in human bioethics, creating more room for recognizing the value of population health, interpersonal relations, solidarity, and ways in which a collective is constituted.

My conclusions are the following:We can distinguish between two sorts of kowledge: intellectual knowledge (knowledge of true propositions) and experiential knowledge (knowledge of how certain experiences feel).If we want the doctrine of divine omniscience to be theologically relevant, we will have to assert that divine omniscience involves experiential as well as intellectual omniscience.In order to be omniscient, God does not need to share all the feelings of His creatures with them. However, in order to be experientially omniscient, God must have (...) undergone at least some experiences Himself.If God would be able to have these experiences only by becoming incarnate, God would need the incarnation in order to become omniscient. In this respect human nature would then be more perfect than the divine nature: it would be capable of knowing things which God could only come to know by becoming human. It is therefore preferable to maintain that the divine nature itself is capable of undergoing certain experiences.If the divine nature were incapable of undergoing any experience, God would nevertheless be able to have a vast knowledge of true propositions concerning experiences. For descriptions of experiences and for the evaluation of these descriptions, however, He would be dependent in principle upon His creatures. (shrink)

Darwin famously held that his use of the term "chance" in evolutionary theory merely "serves to acknowledge plainly our ignorance of the causes of each particular variation". Is this a tenable view today? Or should we revise our thinking about chance in evolution in light of the more advanced, quantitative models of Neo-Darwinian theory, which make substantial use of statistical reasoning and the concept of probability? Is determinism still a viable metaphysical doctrine about biological reality after the quantum revolution in (...) physics, or dowe have to abandon it in favor of an objective indeterminism? In light of such reflections, what is the relevant interpretation of probability in evolutionary theory? Do biologists use the concept of probability because they are finite cognitive agents or because the evolutionary process is fundamentally probabilistic? In this paper, I will show that we do not yet fully understand the nature of chance in evolution. (shrink)

Generally, rational decision-making is conceived as arriving at a decision by a correct application of the rules of logic and statistics. If not, the conclusions are called biased. After an impressive series of experiments and tests carried out in the last few decades, the view arose that rationality is tough for all, skilled field experts not excluded. A new type of planner's counsellor is called for: the normative statistician, the expert in reasoning with uncertainty par excellence. To unravel this view, (...) the paper explores a specific practice of clinical decision-making, namely Evidence-Based Medicine. This practice is chosen, because it is very explicit about how to rationalize practice. The paper shows that whether a decision-making process is rational cannot be assessed without taking into account the environment in which the decisions have to be taken. To be more specific, the decision to call for new evidence should be rational too. This decision and the way in which this evidence is obtained are crucial to validate the base rates. Rationality should be model-based, which means that not only the isolated decision-making process should take a Bayesian updating process as its norm, but should also model the acquisition of evidence (priors and tests results) as a rational process.

My fundamental purpose (1937)--Metaphysical journal (1938-43)--Presence and immortality (1951)--The unfathomable, an unfinished play (March 1919).

In this essay I explore the role of dialectics for how social theory can take account of the problem of structure and agency, or, determination and freedom, in a critical and emancipatory way. I discuss the limits and possibilities of dialectical, and of anti-dialectical, criticisms of Hegelian dialectics. For this purpose, I look at Judith Butler’s discussion of dialectics and the concepts of ‘sex’ and ‘gender’ in her writings between 1987 ( Subjects of Desire ; republished 1999) and 1990 ( (...) Gender Trouble , republished 2000). Butler’s book Gender Trouble remains a key text of contemporary feminist theory. Butler formulates in this book a critique of Simone de Beauvoir’s The Second Sex based on her claim that Beauvoir makes a distinction between ‘sex’ and ‘gender’ that implies the notion of the sexed body as a pre-cultural entity. In her earlier writings, though, her evaluation of de Beauvoir had been much more positive. The change in Butler’s evaluation of de Beauvoir is part of her increasing rejection of dialectics: Butler rejected in Gender Trouble any form of Hegelian dialectics with reference to Luce Irigaray’s (1985) claim that it is ‘phallogocentric’. Although Butler subsequently returned to Hegelian themes, she seems never to have revoked this claim made in her most momentous work. I argue that this change in the theoretical structure of Butler’s argument weakens her critique of identity politics and I suggest reading Butler backwards, from Gender Trouble to the more open discussion of dialectics in her earlier texts. Drawing on Adorno’s Negative Dialectics and other formulations of critical theory, I argue that the valid aspects of the critique of Hegelian dialectics can better be formulated as a dialectical critique of dialectics (Adorno; Butler, 1987a) than as a rejection of dialectics (Derrida; Irigaray; Butler, 1990). Retracing the genealogy of Butler’s argument will be a necessary backdrop, too, for evaluating her more recent comments on the Hegelian and ‘Frankfurt School’ traditions such as her Adorno Lectures given in Frankfurt am Main, Germany, in November 2002. Key Words: Theodor W. Adorno • agency • Judith Butler • Simone de Beauvoir • dialectics • emancipation • G. W. F. Hegel • sex/gender distinction • structure • subjectivity. (shrink)

Propose une étude sur une période particulière de l'histoire du philosophe, celle de sa compromission avec le nazisme en 1933.

The assessment of models in an experiment depends on their material nature and their function in the experiment. Models that are used to make the phenomenon under investigation visible - sensors - are assessed by calibration. However, calibration strategies assume material intervention. The experiment discssed in this paper is an experiment in economics to measure the influence of technology shocks on business cycles. It uses immaterial, mathematical instruments. It appears that calibration did not work for these kinds of models, it (...) did not provide reliable evidence for the facts of the business cycle. (shrink)

The metrology literature neglects a strong empirical measurement tradition in economics, which is different from the traditions as accounted for by the formalist representational theory of measurement. This empirical tradition comes closest to Mari's characterization of measurement in which he describes measurement results as informationally adequate to given goals. In economics, one has to deal with soft systems, which induces problems of invariance and of self-awareness. It will be shown that in the empirical economic measurement tradition both problems have been (...) on the agenda for a long while, and that the proposed solutions to these problems provide clues for the directions in which one could develop a measurement theory that takes account of soft systems.

A typical difference between social science and natural science is the degree in which control is possible. Strategies in both sciences to obtain true facts are consequently different. Measurement errors are due to background noise. Laboratories are environments in which background conditions can be controlled. As a result, accurate observations { measurement results close to the true values of the measurands { can only be obtained in laboratories. Therefore, measuring instruments are built such that they function as mini laboratories. However, (...) observations in social science are usually passive, in the sense that control of background conditions is impossible. Models are built to solve this problem of (lack of) control. They function as nonmaterial laboratories by aiming at precision, that is reducing the spread of the measurement errors. The application of models as measuring instruments necessitates a shift of the requirement of accuracy to the requirement of precision, which is a feature of the instrument and not of the environment.
