This article contributes to the contemporary debate on land and water grabbing through a detailed, qualitative case study of horticultural agribusinesses which have settled in Tanzania, disrupting patterns of land and water use. In this paper we analyse how capitalist settler farms and their upstream and downstream peasant neighbours along the Nduruma river, Tanzania, expand and defend their water use. The paper is based on 3 months of qualitative field work in Tanzania. We use the echelons of rights analysis framework (...) combined with the concept of institutional bricolage to show how this contestation takes place over the full spectrum of actual abstractions, governance and discourses. We emphasise the role different (inter)national development narratives play in shaping day-to-day contestations over water shares and rule-making. Ultimately, we emphasise that water grabbing is not a one-time event, but rather an on-going struggle over different water resources. In addition, we show how a perceived beneficial development of agribusinesses switching to groundwater allows them to avoid peasant-controlled institutions, avoiding further negotiation between the different actors and improving their image among neighbouring communities. This development illustrates how complex and obscured processes of water re-allocation can be without becoming illegal per se. (shrink)

We give a historical overview of the development of almost 50 years of empirical research on the affordances in the past and in the present. Defined by James Jerome Gibson in the early development of the Ecological Approach to Perception and Action as the prime of perception and action, affordances have become a rich topic of investigation in the fields of human movement science and experimental psychology. The methodological origins of the empirical research performed on affordances can be traced back (...) to the mid 1980’s and the works of Warren (1984, 1988) and Michaels (1988). Most of the research in Ecological Psychology performed since has focused on the actualization of discretely defined actions, the perception of action boundaries, the calculation of pi-numbers, and the measurement of response times. The research efforts have resulted in advancements in the understanding of the dynamic nature of affordances, affordances in a social context and the importance of calibration for perception of affordances. Although affordances are seen as an instrumental part of the control of action most studies investigating affordances do not pay attention to the control of the action. We conclude that affordances are still primarily treated as a utility to select behaviour, which creates a conceptual barrier that hinders deeper understanding of affordances. A focus on action-boundaries has largely prevented advancement in other aspects of affordances, most notably an integrative understanding of the role of affordances in the control of action.

De mens is in de afgelopen drie eeuwen vaak vergeleken met allerlei soorten machines. In de achttiende eeuw was de klokmetafoor tamelijk populair; psychologische termen als ‘drijfveer’, ‘van slag raken’ en ‘opgewonden zijn’ herinneren hier nog aan [Vroon and Draaisma, 1985]. In de negentiende eeuw overheerste de stoommachine-metafoor. De psychologie van Freud wordt wel als een uitgewerkte versie van deze metafoor beschouwd [Russelmann, 1983]. Ook uitdrukkingen als ‘uitlaatkleppen’, ‘stoom afblazen’ en ‘iemand opstoken’ zijn eraan te danken. De stoommachine-metafoor wordt nog (...) steeds serieus genomen. Zo pleegt men de menselijke geest in de nieuwe ‘dynamische’ school in de cognitieve wetenschappen bij voorkeur te vergelijken met James Watts centrifugale regulateur (1788), het apparaat dat ervoor zorgt dat een stoommachine op een constant snelheid werkt [van Gelder, 1995, 1998]. De laatste vijftig jaar komt men de metafoor van de seri¨ele digitale computer vaak tegen. Een PC is een voorbeeld van zo’n computer. Hij is serieel omdat de centrale processor slechts ´e´en berekening tegelijk kan uitvoeren; hij is digitaal omdat hij alleen met gehele getallen kan omgaan. Het voorbeeld bij uitstek van een seri¨ele digitale computer is de Turing-machine, waarover aanstonds meer. De seri¨ele digitale computer metafoor is op verschillende manieren op mensen toegepast. Zo beschouwen sommigen de gehele mens als een computer van dit type, terwijl anderen menen dat de afzonderlijke zenuwcellen op deze manier beschreven kunnen worden. In het onderstaande zal ik de vraag bespreken in hoeverre men de mens, of onderdelen van de mens, inderdaad als seri¨ele digitale computer mag opvatten. Ik zal laten zien dat deze vergelijking maar een beperkte waarde heeft. Het valt niet uit te sluiten dat de mens in computationeel opzicht een veel sterker of zwakker soort machine is dan de Turing-machine. (shrink)

In 1926, Mally presented the first formal system of deontic logic. His system had several consequences which Mally regarded as surprising but defensible. It also, however, has the consequence that A is obligatory if and only if A is the case, which is unacceptable from the point of view of any reasonable deontic logic. We describe Mally's system and discuss how it might reasonably be repaired.

It has been argued that ethically correct robots should be able to reason about right and wrong. In order to do so, they must have a set of do’s and don’ts at their disposal. However, such a list may be inconsistent, incomplete or otherwise unsatisfactory, depending on the reasoning principles that one employs. For this reason, it might be desirable if robots were to some extent able to reason about their own reasoning—in other words, if they had some meta-ethical capacities. (...) In this paper, we sketch how one might go about designing robots that have such capacities. We show that the field of computational meta-ethics can profit from the same tools as have been used in computational metaphysics. (shrink)

In order to develop a hermeneutic-phenomenological analysis of testimony, this essay will first argue that testimony is “said in many ways” without being homonymous and that contemporary epistemological approaches to testimony are not capable of accounting for all paradigmatic forms of testimony. Second, it is argued, following and extending the work of Paul Ricoeur, that by emphasizing the sense of engagement or Bezogenheit as a basic characteristic of testimony, we may find another approach to testimony that offers a phenomenological alternative (...) to the observational model of witnessing and the accompanying conception of testimony as report. Third, this approach is further developed and analyzed in terms of the four elements of testimony, namely, subject matter, witness, act of testifying, and addressee. (shrink)

We describe a new way in which theories about the deontic status of actions can be represented in terms of the standard two-sorted extensional predicate calculus. Some of the resulting formal theories are easy to implement in Prolog; one prototype implementation--R. M. Lee's deontic expert shell DX--is briefly described.

This paper urges that if we wish to give social intelligence to our agents, it pays to look at how we acquired our social intelligence ourselves. We are born with drives and motives that are innate and deeply social. Next, as children we are socialized to acquire norms and values and to understand rituals large and small. These social elements are the core of our being. We capture them in the acronym GRASP: Groups, Rituals, Affiliation, Status, Power. As a consequence, (...) economic rationality or logical reasoning do not suffice when it comes to social intelligence. Basic features of our social behaviour, of the kind that one sees early in the lives of children, need to be prominent. These include fear, love, and aggression. They extend to the combination of these drives with basic social clues from the environment such as big and small, good and bad, as well as culture-specific specializations of these. This will make agents respond differentially to inferred attributes such as gender, age, group membership. This level of universality in social intelligence should receive our full attention. The general insights gained can then be re-used in myriad implementations to specific modelling issues. (shrink)

In 1926, Ernst Mally proposed a number of deontic postulates. He added them as axioms to classical propositional logic. The resulting system was unsatisfactory because it had the consequence that A is the case if and only if it is obligatory that A. We present an intuitionistic reformulation of Mally’s deontic logic. We show that this system does not provide the just-mentioned objectionable theorem while most of the theorems that Mally considered acceptable are still derivable. The resulting system is unacceptable (...) as a deontic logic, but it does make sense as a lax logic in the modern sense of the word. (shrink)

The paper presents a formal explication of the early Wittgenstein's views on ontology, the syntax and semantics of an ideal logical language, and the propositional attitudes. It will be shown that Wittgenstein gave a "language of thought" analysis of propositional attitude ascriptions, and that his ontological views imply that such ascriptions are truth-functions of (and supervenient upon) elementary sentences. Finally, an axiomatization of a quantified doxastic modal logic corresponding to Tractarian semantics will be given.

We describe a new way in which theories about the deontic status of actions can be represented in terms of the standard two-sorted first-order extensional predicate calculus. Some of the resulting formal theories are easy to implement in Prolog; one prototype implementation—R. M. Lee's deontic expert shell DX—is briefly described.

We present axiomatizations of the deontic fragment of Anderson's relevant deontic logic (the logic of obligation and related concepts) and the eubouliatic fragment of Anderson's eubouliatic logic (the logic of prudence, safety, risk, and related concepts).

We discuss three aspects of the intuitionistic reformulation of Mally’s deontic logic that was recently proposed ). First, this reformulation is more similar to Standard Deontic Logic than appears at first sight: like Standard Deontic Logic, it is Kanger reducible and Anderson reducible to alethic logic and it has a semantical interpretation that can be read in deontic terms. Second, this reformulation has an extension that provides 100% of the theorems stated by Mally himself. Third, it is interesting to view (...) Mally’s original deontic logic as an extension of this reformulation. (shrink)

Despite the urgency of this issue, AI still struggles to represent social life. This article presents a comprehensive agent-based model that investigates status-power dynamics in groups. Kemper’s sociological status–power theory of social relationships, and a literature review on school children in middle youth, is its basis. The model allows us to investigate causation of the near-ubiquitous phenomenon that females have lower social status on average than males. Possible causes included in the model are children’s dispositional traits (kindness, beauty, and physical (...) power), schoolyard culture (social acceptability of fighting), behavioural strategy (amount of rough-and-tumble play) and the balance between public and dyadic sources of status. An agent-based model of a virtual schoolyard was created in which the children assemble in changing groups and mutually confer status. The status conferred upon a child modifies the status it holds. Rough-and-tumble is modelled as ambiguous: it is intended as a status conferral, but may be perceived as a power move. Running many trials of the model we found that in time, depending on the parameter settings, a gender-based status gap emerged. Rough-and-tumble play had more impact on emergent status differences than did physical power differences. Social acceptability of fighting also strongly moderated the resulting status gap. Placing more weight on dyadic relationship could alleviate status loss. All these model behaviours are in line with empirical findings of child behaviour studies at schools. They have face validity for social status issues in the adult world. We conclude from this that this kind of agent-based model merits use in studying the status–power dynamics of other issues in child behaviour, or indeed in social behaviour in general. (shrink)

This paper explores the function of cities in the knowledge economy. The knowledge economy asks for “creative cities,” i.e. competitive urban areas that combine concentration, diversity, instability and a positive reputation. For a review of the concept of creative cities from a historical and theoretical perspective, we draw the conclusion that knowledge, creativity and innovation cannot be planned from scratch by local governments. However, creative cities par excellence such as Austin, the Øresund and Barcelona demonstrate that local policymakers in fact (...) can play a part in preparing cities for the requirements of the knowledge economy. We conclude that local governments can increase the chance that urban creativity emerges by providing the appropriate underlying framework conditions. (shrink)

Inspired by the recent rediscovery of work of Schumpeter in science and policymaking the author reviews and appraises Schumpeterian theory and that of his followers in innovation studies. Although Schumpeter’s vision suffers from some defects, I argue that there is more to learn from this author than his well-known idea of “creative destruction”. In particular, Schumpeter’s view on innovation policy is something that may have vital relevance to today’s increasingly policy-dominated world. We therefore conclude that besides his key ideas on (...) innovation-led development also his policy view should be regarded as a significant legacy in innovation studies. (shrink)

We present a new axiomatization of the deontic fragment of Anderson's relevant deontic logic, give an Andersonian reduction of a relevant version of Mally's deontic logic previously discussed in this journal, study the effect of adding propositional quantification to Anderson's system, and discuss the meaning of Anderson's propositional constant in a wide range of Andersonian deontic systems.

In this essay, the author takes up the responses of Dennis J. Schmidt and Carolyn Culbertson to his monograph The Voice of Misery: A Continental Philosophy of Testimony. It first observes that both respondents have a shared interest in the ethical dimension of the question of testimony, which has much to do with the exceptional subject matter, namely that of bare life, that The Voice of Misery takes as its point of departure to analyze what testimony is. In the first (...) section, the author engages with Schmidt’s account of the importance of Heidegger, Plato’s myth of Er and Celan’s poetry for thinking testimony and shows how exactly these references allow us to think the ethos and the ethics of textimony. In the second section, he discusses the three questions Culbertson raised concerning the practical, more everyday stakes of testimony in relation to the epistemology of testimony and the question of epistemic justice.

The Dutch health care system is developing a two, or multiple, tier system. How can moral principles be of help in assessing whether this is the right track? Instead of dismissing as unhelpful the principles that have been suggested so far and exchanging them for other, usually more complex, principles, it is suggested that the methods of moral inquiry be reconsidered.

A systematic study of testimony rooted in contemporary continental philosophy and drawing on literary case studies. From analytic epistemology to gender theory, testimony is a major topic in philosophy today. Yet, one distinctive approach to testimony has not been fully appreciated: the recent history of contemporary continental philosophy offers a rich source for another approach to testimony. In this book, Gert-Jan van der Heiden argues that a continental philosophy of testimony can be developed that is guided by those forms (...) of bearing witness that attest to limit experiences of human existence, in which the human is rendered mute, speechless, or robbed of a common understanding. In the first part, Van der Heiden explores this sense of testimony in a reading of several literary texts, ranging from Plato’s literary inventions to those of Kierkegaard, Melville, Soucy, and Mortier. In the second part, based on the orientation offered by the literary experiments, Van der Heiden offers a more systematic account of testimony in which he distinguishes and analyzes four basic elements of testimony. In the third part, he shows what this analysis implies for the question of the truth and the truthfulness of testimony. In his discussion with philosophers such as Heidegger, Derrida, Lyotard, Agamben, Foucault, Ricoeur, and Badiou, Van der Heiden also provides an overview of how the problem of testimony emerges in a number of thinkers pivotal to twentieth- and twenty-first-century thought. “The Voice of Misery is a special book. Van der Heiden has presented an argument that is poised to challenge discourse in analytic philosophy, reshape approaches in continental philosophy, and give new orientation to interdisciplinary research in continental philosophy and literary theory. The book will find a large readership across the discipline of philosophy and in several areas of the humanities.” — Theodore George, author of Tragedies of Spirit: Tracing Finitude in Hegel’s Phenomenology.

ABSTRACTThe remarkable philosophical present-day turn to Paul pays a lot of attention to the particular role played by the famous distinctions that structure Paul’s rhetoric such as the distinction between faith and law, life and death, and spirit and flesh. These distinctions lead to the question of whether Paul endorses a dualism or not. In this essay, the author investigates Badiou’s and Agamben’s readings of Paul and asks whether one cannot find a form of dialectics rather than dualism in these (...) readings. The concept of the exception seems to corroborate this suggestion. To examine whether this suggestion makes sense, the author first discusses Badiou’s focus on the antidialectics of death and resurrection as well as the dialectical remnants in Badiou’s reading of Paul. Subsequently, the author analyses Agamben’s dialectical account of the Pauline terms katargein, chrēsis and charis. (shrink)

In 1926, Mally proposed the first formal deontic system. As Mally and others soon realized, this system had some rather strange consequences. We show that the strangeness of Mally's system is not so much due to Mally's informal deontic principles as to the fact that he formalized those principles in terms of the propositional calculus. If they are formalized in terms of relevant logic rather than classical logic, one obtains a system which is related to Anderson's relevant deontic logic and (...) not nearly as strange as Mally's own system.

Health technology assessment consists of thesystematic study of the consequences of theintroduction or continued use of the technology in aparticular context, with the explicit objective toarrive at a judgment of the value or merit of thetechnology. Ideally, it is aimed at assessing allaspects of a given technology or group oftechnologies, including non-technical, e.g.socio-ethical, aspects. However, methods for assessingsocio-ethical implications of health technology arerelatively undeveloped and few mechanisms exist totake action based on the results of such evaluations.Still, the examples of cochlear (...) inplants and other cases illustratethat HTA is not a matter of merely collecting thefacts about a technology. The facts must beplausible and relevant from a particular framework,which is not always shared by different groups. It ishere that socio-ethical aspects are encountered. Ifhealth technology assessment aims to enhance theaccountability of the decision making processregarding funding and use of health technology, it isa major challenge to assessors of health technologiesto deal adequately with existing value pluralism. Inthis respect interactive evaluation may have somethingto offer. (shrink)

When thinking about ethics, technology is often only mentioned as the source of our problems, not as a potential solution to our moral dilemmas. When thinking about technology, ethics is often only mentioned as a constraint on developments, not as a source and spring of innovation. In this paper, we argue that ethics can be the source of technological development rather than just a constraint and technological progress can create moral progress rather than just moral problems. We show this by (...) an analysis of how technology can contribute to the solution of so-called moral overload or moral dilemmas. Such dilemmas typically create a moral residue that is the basis of a second-order principle that tells us to reshape the world so that we can meet all our moral obligations. We can do so, among other things, through guided technological innovation. (shrink)

_Phenomenological Perspectives on Plurality_ offers twelve essays that discuss how the question of plurality is thought in contemporary continental philosophy. Its essays investigate how this issue influences topics in ontology, aesthetics, and social and political philosophy.

Symptomatic of the crisis of the current global political order are the millions of displaced that have fled their homes but are not allowed to enter the country in which they seek refuge. Instead, they are placed in camps. To understand the site of the camp and the bare life it produces, testimonies of refugees are indispensable. This essay aims to examine and listen to these testimonies by, first, introducing the notion of testimony and some of the characteristics of the (...) testimony of refugees; second, examining what it means to listen to testimony and which role is played therein by the narrative, literary structure of testimony; and, third, by interpreting the form of life to which the testimonies of the camp attest, which several witnesses describe as a life in “limbo.” This essay concludes with some brief remarks on the relation between experience, truth, and language in testimony.

In this article, I will explore the archeology of the concept of attestation in Ricoeur’s work. In a brief discussion of his early reflections on Husserl’s concept of the ego (as an example of reflexive philosophy), I show how the dialectic of trust and suspicion enters Ricoeur’s hermeneutic concerns. I argue that this dialectics remains present in his account of attestation. By a brief confrontation with Heidegger’s notion of attestation as developed in Being and Time, I show that the uniqueness (...) of Ricoeur’s account of attestation is to be found in this dialectic of trust and suspicion that he reinterprets in his later work in light of the concept of attestation.

Both Agamben and Nancy introduce the notions of ban and abandonment to understand the contemporary experience of the loss of tradition. Whereas Nancy reinterprets hermeneutics in light of this abandonment, Agamben tries to move beyond this account of abandonment. In this article, I examine how these two positions are related and to which conceptions of hermeneutics and tradition they give rise. First, I explore how the notion of abandonment provides an alternative to Gadamer’s account of hermeneutics, which focuses on the (...) belonging to tradition. Subsequently, I discuss which accounts of hermeneutics and tradition Nancy develops in his discussion of ban and abandonment. Finally, I discuss how Agamben tries to move beyond Nancy’s account of the ban by suggesting that the ban of tradition be broken along the lines of thought he finds in the work of Benjamin. I conclude by showing how this latter suggestion might give rise to a third figure of hermeneutics that discovers, beyond belonging to the past and being banned from the past, the ‘potentialization’ of the past.

In Le Sens du monde, Nancy argues that “some value of scintillating phenomenality remains invincibly attached” to Badiou’s notion of the event. This paper examines to what extent Nancy’s comments still apply to Badiou’s phenomenology of the event developed in Logiques des mondes. In particular, although Badiou provides a thorough account of the event from the perspective of the consequences it enables, I show on the basis of Nancy’s suggestion that he tends to neglect an account of the event from (...) the perspective of its occurrence and its passage.
