Aggleton & Brown propose that familiarity-based recognition depends on a perirhinal-medial dorsal thalamic system. However, connections between these structures are sparse or absent. In contrast, the perirhinal cortex is connected to midline/intralaminar nuclei. In a human, a lesion in this thalamic domain, sparing the medial dorsal nucleus, impaired familiarity-based recognition while sparing recollective-based recognition. It is thus more likely that the intralaminar/midline nuclei are involved in recognition.

L.E.J. Brouwer made a mistake in the formulation of his famous bar theorem, as was pointed out by S.C. Kleene. By repeating this mistake several times, Brouwer has caused confusion. We consider the assumption underlying his bar theorem, calling it Brouwer’s Thesis. This assumption is not refuted by Kleene’s example and we use it to obtain a conclusion different from Brouwer’s. Thus we come to support a view first expressed and defended by E. Martino and P. Giaretta in [Martino 1981]. (...) We also indicate that Brouwer’s Thesis has many more applications than Brouwer dreamt of. (shrink)

To what use can causal claims established in good policy studies be put? We isolate two reasons inferences from study to target fail. First, policy variables do not produce results on their own; they need helping factors. The distribution of helping factors is likely to be unique or local for each study, so one cannot expect external validity to be all that common. Second, researchers often give too concrete a description of the cause in the study for it to carry (...) over to the target. Abstraction is necessary to get causes that travel. There is no sure-fire way to guard against these problems. But the unavailability of one perfect tool does not imply there are no second best contrivances. Two general pointers for Good Practice in policy advice follow from our diagnosis: focus on the concrete details in the target and use cross discipline heuristics that diversify background knowledge.

In een tijd waarin 'nepnieuws' zich steeds nadrukkelijker naar de voorgrond dringt, is de vraag naar wat waarheid is buitengewoon belangrijk. Ook vragen of wetenschappelijke studies betrouwbaar zijn en of een (sociale) wetenschapper neutraal beleidsadvies kan geven zijn aan de orde van de dag. Daarop kan de wetenschapsfilosofie antwoord geven. Dit boek biedt kritische reflectie op belangrijke vraagstukken in de filosofie van de sociale wetenschappen. De sociale wetenschapper wordt ingeleid in wetenschapsfilosofische thema's als causaliteit, verklaringsstijlen, reductionisme en holisme, statistiek, modellen (...) en onderzoeksparadigma's. Daarnaast is er ruim aandacht voor de wetenschappelijke praktijk en de positie die (sociale) wetenschappers innemen in het maatschappelijk debat. Veel wetenschappers zijn immers geneigd liever neutraal te blijven en zich niet in een maatschappelijk debat te mengen. Maar is dat eigenlijk wel wenselijk en mogelijk?"--Page 4 of cover. (shrink)

The purpose of this paper is to lay bare the major problems underlying the concept of downward causation as discussed within the perspective of the present interest for phenomena that are characterized by self-organization. In our Discussion of the literature, we have focussed on two questions: (1) What sorts of things are said to be, respectively, causing and caused within the context of downward causation? And (2) What is the meaning of 'causing' in downward causation? We have concluded that the (...) concept of 'downward causation' is muddled with regard to the meaning of causation and fuzzy with regard to the nature of the causes and the effects. Moreover, we have concluded that 'causation' in respect of 'downward causation' is usually understood in terms of explanation and determination rather than in terms of causation in the sense of 'bringing about'. Thus, the term 'downward causation' is badly chosen. (shrink)

Speciation is a central but elusive issue in evolutionary biology. Over the past sixty years, the subject has been studied within a framework conceived by Ernst Mayr and Theodosius Dobzhansky and subsequently developed further by numerous other workers. In this “isolation” theory, the evolution of reproductive isolation is a key element of speciation; natural selection is given only secondary importance while gene flow is considered prohibitive to the process. In this paper, I argue that certain elements in this approach have (...) produced confusion and irreconcilability among students of speciation. The more prominent debates in speciation (i.e., the species definition, sympatry/allopatry, and the role of reinforcement) all derive from an inherent conflict between the “isolation” theory and Darwin's “selection” view on species and speciation (in which disruptive selection is crucial). New data, mainly from field ecology, molecular population genetics, laboratory studies with Drosophila and computer analysis, all suggest that the isolation theory may no longer be the most desirable vantage point from which to explore speciation. Instead, environmental selection in large populations, often unimpeded by ongoing gene flow, appears to be the decisive element. The traditional preoccupation with reproductive isolation has created gaps in our knowledge of several crucial issues, mainly regarding the role of environmental selection and its connection with mate selection.

To what use can causal claims established in good studies be put? We give examples of studies from which inaccurate inferences were made about target policy situations. The usual diagnosis is that the studies in question lack external validity, which means that the same results do not hold in the target as in study. That’s a label that just repeats what we already knew. We offer a deeper analysis. Our analysis points to the need for interdisciplinarity and to the demand (...) to focus not on the study – as the expression ‘external validity’ invites you to do – but on the target. The call for interdisciplinary approaches to real life problems is common since it is widely acknowledged that what happens in the real world seldom falls under the auspices of any single research domain. Our focus is on one specific real life problem: how to use causal claims from good studies to help predict whether the policies tested will work in a new situation. Our analysis of what it takes to back up these predictions points up very specific stages in the process of prediction where we are bound to get it wrong if we do not diversify our concepts, our knowledge and our methods. We isolate two reasons inferences from study to target fail. First, policy variables do not produce results on their own; they need helping factors.

Several studies have focused on the effects of corporate social responsibility fit on external stakeholders’ evaluations of CSR activities, attitudes towards companies or brands, and behaviors. The results so far have been contradictory. A possible reason may be that the concept of CSR fit is more complicated than previously assumed. Researchers suggest that there may be different types of CSR fit, but so far no empirical research has focused on a typology of CSR fit. This study fills this gap, describing (...) a qualitative content analysis of the congruence between six organizations and their various CSR activities. Ten annual reports and CSR reports were analyzed, and 102 specific CSR activities were identified. The results show that two levels of fit must be distinguished: based on the means for and the intended ends of the CSR activity. Furthermore, six different types of fit were found, focusing on products and services, production processes, environmental impact, employees, suppliers, and geographical location. Considering the above variety of fit possibilities, the findings emphasize the role of CSR communication as a means of creating fit perceptions. (shrink)

In this paper I examine one well-known attempt to justify the claim that thoughts are intrinsically structured, Evans’s justification of the Generality Constraint. I compare this with a rival account, proposed by Peaocke. I end by suggesting that a naïve, Aristotelian realist has no difficulty at all in providing a justification of the Generality Constraint, which is therefore a view that deserves serious consideration.

Michael Ayers’s Knowing and Seeing: Groundwork for a New Empiricism is a rich and detailed development of two ideas. The first is that perception presents reality to us directly in a perspicuous way. We thus acquire primary knowledge of the world: “knowledge gained by being evidently, self-consciously, in direct cognitive contact with the object of the knowledge.” (Ayers 2019, 63) The second idea is that concepts are not needed in perception. In this article, the author examines Ayers’s view. The author (...) proceeds as follows: In the first section, he identifies the target of Ayers’s attacks, conceptualism. He then describes why many philosophers have felt this conceptualist view to be attractive. In the next section, he discusses Ayers’s criticisms of conceptualism in an attempt to disentangle these criticisms from the statement of his positive view, which the author discusses in the following section. He ends by describing some problems for Ayers’s positive position that are, so he argues, the result of his vehement opposition to conceptualism. (shrink)

Julian Reiss finds an insoluble paradox in the claims that economic models are at the same time false, nevertheless explanatory, and that only true explanations explain. But the claim that they are false is itself false. A closer look at what ?truth? may mean is needed.

This essay by the Dutch modernist writer Menno ter Braak, ‘National Socialism as a Doctrine of Rancour’, was written in 1937 just before the German annexation of the Netherlands. It is a rare examination of how the concept ressentiment can be used to analyse 1930s National Socialism, outlining the ways in which the fascist variant of ressentiment is both distinctive and also, nonetheless, connected to its democratic and socialist versions. The essay develops Nietzsche’s and Scheler’s understandings of ressentiment by (...) applying them to fascism, insisting on the centrality of the moral sentiment of ressentiment not just to populism but to all forms of democracy, and to any philosophical or political orientation committed to an ideal of equality, indeed to all of modern society, culture and politics.

Stipulating universal propositions with a ceteris paribus clause is normal practice in science and especially in economics. Yet there are several problems associated with the use of ceteris paribus clauses in theorising and in policy matters. This paper first investigates three questions: how can ceteris paribus clauses be non-vacuous? How can ceteris paribus laws be true? And how can they help in formulating successful policy interventions in a diversity of contexts? It turns out that ceteris paribus clauses are not always (...) used legitimately. They are meant to fence off a theory from disturbing factors, but economists who do not specify the clause well enough tend to fence variables in rather than off. In such cases, it would be better to use theoretical abstraction, which is something very different from the use of ceteris paribus clauses. However, abstract theorising conceptually leads one away from the concrete detail of real world situations in which policies take place. Hence, a fourth question arises: how can policy interventions be properly designed on the basis of abstract laws? To answer this question, I defend interdisciplinarity in concept choice. (shrink)

This article revisits theologian Ulrich Duchrow’s three-decade-old use of the Protestant notion of status confessionis to denounce the capitalist global economy. Scholars quickly dismissed Duchrow’s argument; however, philosopher Thomas Pogge has developed a remarkable “negative duty”—based critique of the current global economic order that might help revitalize Duchrow’s position. The article argues that sound reasons exist for the churches to declare the contemporary world economy a—provisionally termed—status confessionis minor. After explaining the inadequacy of Duchrow’s original position and summarizing Pogge’s account, (...) the article develops a twofold argument. First, Pogge’s in-depth inquiry into the world economy gives Duchrow’s call for a status confessionis a strong yet narrowing economic foundation. Second, to declare the world economy a status confessionis minor is theological-ethically justifiable if the limited though indispensable “prophetic” significance of doing so is acknowledged. Thus, Duchrow’s approach is justified, but only partially. (shrink)

The late influential American intellectual Michael Novak was a self-declared devotee of Reinhold Niebuhr, arguably the foremost twentieth-century American theologian. Novak’s The Spirit of Democratic Capitalism (1982) was an attempt to fill the political-economic lacuna in Niebuhr’s thought. The present article offers a Niebuhrian irony–focused response to Novak’s democratic capitalism in view of climate change as probably the greatest threat facing humanity. Novak quite successfully extended Niebuhrian ideas into a theology-based vision of democratic capitalism as the only political-economic system effective (...) in widely lifting people out of poverty. Yet he failed to acknowledge human-induced climate change as beyond reasonable doubt and rooted in the predominantly American invention of a fossil energy–based capitalist political economy. This article’s thesis is that Novak’s democratic capitalism entails Niebuhrian irony: the virtue it displays about resources becomes a vice due to Novak’s irresponsible post–Spirit of Democratic Capitalism attempt to represent democratic capitalism as innocent of any dangerous climate-change implications.

The paper is a contribution to intuitionistic reverse mathematics. We introduce a formal system called Basic Intuitionistic MathematicsBIM, and then search for statements that are, over BIM, equivalent to Brouwer’s Fan Theorem or to its positive denial, Kleene’s Alternative to the Fan Theorem. The Fan Theorem is true under the intended intuitionistic interpretation and Kleene’s Alternative is true in the model of BIM consisting of the Turing-computable functions. The task of finding equivalents of Kleene’s Alternative is, intuitionistically, a nontrivial extension (...) of the task of finding equivalents of the Fan Theorem, although there is a certain symmetry in the arguments that we shall try to make transparent. We introduce closed-and-separable subsets of Baire space N\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{N}}$$\end{document} and of the set R\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{R}}$$\end{document} of the real numbers. Such sets may be compact and also positively noncompact. The Fan Theorem is the statement that Cantor space C\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{C}}$$\end{document}, or, equivalently, the unit interval [0, 1], is compact and Kleene’s Alternative is the statement that C\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${\mathcal{C}}$$\end{document}, or, equivalently, [0, 1], is positively noncompact. The class of the compact closed-and-separable sets and also the class of the closed-and-separable sets that are positively noncompact are characterized in many different ways and a host of equivalents of both the Fan Theorem and Kleene’s Alternative is found.

The author proved in his Ph.D. Thesis [W. Veldman, Investigations in intuitionistic hierarchy theory, Ph.D. Thesis, Katholieke Universiteit Nijmegen, 1981] that, in intuitionistic analysis, the positively Borel subsets of Baire space form a genuinely growing hierarchy: every level of the hierarchy contains sets that do not occur at any lower level. It follows from this result that there are natural examples of analytic and also of co-analytic sets that are not positively Borel. It turns out, however, that, in intuitionistic (...) analysis, one may give surprisingly different and, in some sense, much more simple examples of analytic and co-analytic sets that fail to be positively Borel. In the paper, two such examples are given. In proving them correct, one obtains new proofs of the Borel Hierarchy Theorem. Brouwer’s Continuity Principle plays a crucial role in arguments. (shrink)
