This book explores the constitutional, legally binding dimension to legisprudence in the light of the German Federal Constitutional Court's approach to rational lawmaking. Over the last decades this court has been remarkably active in applying legisprudential criteria and standards when reviewing parliamentary laws. It has thus supplied observers with a unique material to analyse the lawmakers' duty to legislate rationally, and to assess the virtues and drawbacks of this strand of judicial control in a constitutional democracy. By bringing together legislation (...) experts and public law scholars to elaborate on 'legisprudence under review', this contributed volume aspires to shed light on the constitutionalisation of rational lawmaking as a controversial trend gaining ground in both national and international jurisdictions. The book is divided into five parts. Part I frames the two key issues pervading the whole collection: the intricate relationship between judicial review and democracy, on the one hand, and the possibility of improving and rationalizing the task of legislation under the current circumstances of politics, on the other. Part II provides an overview of the judicial review of rational lawmaking, laying special emphasis on the duty of legislative justification imposed on lawmakers by the German Constitutional Court. Part III is devoted to the review of the systemic rationality of legislation, in particular to the requirements of legislative consistence and coherence as developed by this court. Contributions in Part IV revolve around the judicial scrutiny of the socio-empirical elements of rational lawmaking, with the control of legislative facts and impacts and the problem of symbolic laws being the central topics. Finally, Part V draws on the German case law to discuss the links between rational lawmaking, balancing and proportionality, and the interdependence between process review and substantive review of legislation.

Axiom weakening is a novel technique that allows for fine-grained repair of inconsistent ontologies. In a multi-agent setting, integrating ontologies corresponding to multiple agents may lead to inconsistencies. Such inconsistencies can be resolved after the integrated ontology has been built, or their generation can be prevented during ontology generation. We implement and compare these two approaches. First, we study how to repair an inconsistent ontology resulting from a voting-based aggregation of views of heterogeneous agents. Second, we prevent the generation of (...) inconsistencies by letting the agents engage in a turn-based rational protocol about the axioms to be added to the integrated ontology. We instantiate the two approaches using real-world ontologies and compare them by measuring the levels of satisfaction of the agents w.r.t. the ontology obtained by the two procedures. (shrink)

Ontology engineering is a hard and error-prone task, in which small changes may lead to errors, or even produce an inconsistent ontology. As ontologies grow in size, the need for automated methods for repairing inconsistencies while preserving as much of the original knowledge as possible increases. Most previous approaches to this task are based on removing a few axioms from the ontology to regain consistency. We propose a new method based on weakening these axioms to make them less restrictive, employing (...) the use of refinement operators. We introduce the theoretical framework for weakening DL ontologies, propose algorithms to repair ontologies based on the framework, and provide an analysis of the computational complexity. Through an empirical analysis made over real-life ontologies, we show that our approach preserves significantly more of the original knowledge of the ontology than removing axioms. (shrink)

Ontologies represent principled, formalised descriptions of agents’ conceptualisations of a domain. For a community of agents, these descriptions may differ among agents. We propose an aggregative view of the integration of ontologies based on Judgement Aggregation (JA). Agents may vote on statements of the ontologies, and we aim at constructing a collective, integrated ontology, that reflects the individual conceptualisations as much as possible. As several results in JA show, many attractive and widely used aggregation procedures are prone to return inconsistent (...) collective ontologies. We propose to solve the possible inconsistencies in the collective ontology by applying suitable weakenings of axioms that cause inconsistencies. (shrink)

Many research fields concerned with the processing of information contained in human faces would benefit from face stimulus sets in which specific facial characteristics are systematically varied while other important picture characteristics are kept constant. Specifically, a face database in which displayed expressions, gaze direction, and head orientation are parametrically varied in a complete factorial design would be highly useful in many research domains. Furthermore, these stimuli should be standardised in several important, technical aspects. The present article presents the freely (...) available Radboud Faces Database offering such a stimulus set, containing both Caucasian adult and children images. This face database is described both procedurally and in terms of content, and a validation study concerning its most important characteristics is presented. In the validation study, all frontal images were rated with respect to the shown facial expression, intensity of expression, clarity of expression, genuineness of expression, attractiveness, and valence. The results show very high recognition of the intended facial expressions. (shrink)

Self-control provides one cooperative explanation for “purity.” Other types of cooperation provide additional explanations. For example, individuals compete for status by displaying high-value social and sexual traits, which are moralised because they reduce the mutual costs of conflict. As this theory predicts, sexually unattractive traits are perceived as morally bad, aside from self-control. Moral psychology will advance more quickly by drawing on all theories of cooperation.

We introduce a family of operators to combine Description Logic concepts. They aim to characterise complex concepts that apply to instances that satisfy \enough" of the concept descriptions given. For instance, an individual might not have any tusks, but still be considered an elephant. To formalise the meaning of "enough", the operators take a list of weighted concepts as arguments, and a certain threshold to be met. We commence a study of the formal properties of these operators, and study some (...) variations. The intended applications concern the representation of cognitive aspects of classi cation tasks: the interdependencies among the attributes that de ne a concept, the prototype of a concept, and the typicality of the instances.

Many aspects of how humans form and combine concepts are notoriously difficult to capture formally. In this paper, we focus on the representation of three particular such aspects, namely overexten- sion, underextension, and dominance. Inspired in part by the work of Hampton, we consider concepts as given through a prototype view, and by considering the interdependencies between the attributes that define a concept. To approach this formally, we employ a recently introduced family of operators that enrich Description Logic languages. These (...) operators aim to characterise complex concepts by collecting those instances that apply, in a finely controlled way, to ‘enough’ of the concept’s defin- ing attributes. Here, the meaning of ‘enough’ is technically realised by accumulating weights of satisfied attributes and comparing with a given threshold that needs to be met. (shrink)

Jewish philosophy is often presented as an addendum to Jewish religion rather than as a rich and varied tradition in its own right, but the _History of Jewish Philosophy_ explores the entire scope and variety of Jewish philosophy from philosophical interpretations of the Bible right up to contemporary Jewish feminist and postmodernist thought.

From the ninth to the fifteenth centuries Jewish thinkers living in Islamic and Christian lands philosophized about Judaism. Influenced first by Islamic theological speculation and the great philosophers of classical antiquity, and then in the late medieval period by Christian Scholasticism, Jewish philosophers and scientists reflected on the nature of language about God, the scope and limits of human understanding, the eternity or createdness of the world, prophecy and divine providence, the possibility of human freedom, and the relationship between divine (...) and human law. Though many viewed philosophy as a dangerous threat, others incorporated it into their understanding of what it is to be a Jew. This Companion presents all the major Jewish thinkers of the period, the philosophical and non-philosophical contexts of their thought, and the interactions between Jewish and non-Jewish philosophers. It is a comprehensive introduction to a vital period of Jewish intellectual history. (shrink)

In comparing different risk elicitation methods under the assumptions of expected utility theory, previous studies have found significant differences in the elicited risk attitudes. This paper extends this line of research to consider cumulative prospect theory by comparing risk attitudes and probability weightings determined using two elicitation methods: the method by Tanaka et al. :557–571, 2010; TCN method) and the method by Wakker and Deneffe :1131–1150, 1996; WD method). We demonstrate that the two methods reveal significantly different mean values for (...) the measured risk attitudes. Participants are classified on average as moderately risk-averse using the TCN method, whereas the same individuals are classified as nearly risk-neutral using the WD method. Moreover, we find that on average, participants overweight low probabilities and underweight high probabilities to a greater extent with the WD method than with the TCN method. Therefore, the different elicitation methods, that both consider probability weighting, can lead to different measured values of risk attitude and probability weighting. (shrink)

Throughout the biological and biomedical sciences there is a growing need for, prescriptive ‘minimum information’ (MI) checklists specifying the key information to include when reporting experimental results are beginning to find favor with experimentalists, analysts, publishers and funders alike. Such checklists aim to ensure that methods, data, analyses and results are described to a level sufficient to support the unambiguous interpretation, sophisticated search, reanalysis and experimental corroboration and reuse of data sets, facilitating the extraction of maximum value from data sets (...) them. However, such ‘minimum information’ MI checklists are usually developed independently by groups working within representatives of particular biologically- or technologically-delineated domains. Consequently, an overview of the full range of checklists can be difficult to establish without intensive searching, and even tracking thetheir individual evolution of single checklists may be a non-trivial exercise. Checklists are also inevitably partially redundant when measured one against another, and where they overlap is far from straightforward. Furthermore, conflicts in scope and arbitrary decisions on wording and sub-structuring make integration difficult. This presents inhibit their use in combination. Overall, these issues present significant difficulties for the users of checklists, especially those in areas such as systems biology, who routinely combine information from multiple biological domains and technology platforms. To address all of the above, we present MIBBI (Minimum Information for Biological and Biomedical Investigations); a web-based communal resource for such checklists, designed to act as a ‘one-stop shop’ for those exploring the range of extant checklist projects, and to foster collaborative, integrative development and ultimately promote gradual integration of checklists.

Biology and history are often viewed as closely related disciplines, with biology informed by history, especially in its task of charting our evolutionary past. Maximizing the opportunities for cross-fertilization in these two fields requires an accurate reckoning of their commonalities and differences-precisely what this volume sets out to achieve. Specially commissioned essays by a team of recognized international researchers cover the full panoply of topics in these fields and include notable contributions on the correlativity of evolutionary and historical explanations, applying (...) to history the latest causal-mechanical approach in the philosophy of biology, and the question of generalized laws that might pertain across the two subjects. The collection opens with a vital interrogation of general issues on explanation that apart from potentially fruitful areas of interaction (could the etiology of the causal-mechanical perspective in biology account for the historical trajectory of the Roman Empire?) this volume also seeks to chart relative certainties distinguishing explanations in biology and history. It also assesses techniques such as the use of probabilities in biological reconstruction, deployed to overcome the inevitable gaps in physical evidence on early evolution. Methodologies such as causal graphs and semantic explanation receive in-depth analysis. Contributions from a host of prominent and widely read philosophers ensure that this new volume has the stature of a major addition to the literature. (shrink)

When people combine concepts these are often characterised as “hybrid”, “impossible”, or “humorous”. However, when simply considering them in terms of extensional logic, the novel concepts understood as a conjunctive concept will often lack meaning having an empty extension (consider “a tooth that is a chair”, “a pet flower”, etc.). Still, people use different strategies to produce new non-empty concepts: additive or integrative combination of features, alignment of features, instantiation, etc. All these strategies involve the ability to deal with conflicting (...) attributes and the creation of new (combinations of) properties. We here consider in particular the case where a Head concept has superior ‘asymmetric’ control over steering the resulting concept combination (or hybridisation) with a Modifier concept. Specifically, we propose a dialogical approach to concept combination and discuss an implementation based on axiom weakening, which models the cognitive and logical mechanics of this asymmetric form of hybridisation.

This self-interview is the responsive document coming forth from the post-conference camaraderie. The four “Žižekian Performers” – found with themselves personally, creatively, and academically following the 2014 International Žižek Studies Conference. As a self-interview document that mimics the gameplay of Žižek himself in his own self-interview from his The Metastases of Enjoyment where he puts on the guise of the “big Other” to examine himself, we four performers here examine ourselves, each other, our work, and each other’s work to produce (...) this post-partum collaborative essay. In our collective project, we outline our individual performances from the Conference, each stake a claim and personal response to the critical question of what is a “Žižekian Performance,” and identify and discuss other synergies that emerged and exist amid our work in the form of cross-examinations and self-examinations. Ultimately, this group’s self-interview blazes the way for performance to interpenetrate the “Žižekian” and to intervene wherever theory, investigation, and presentation may lie. (shrink)

1 Evidence-based policy requires researchers to provide the answers to ecological questions that are of interest to policy makers. To find out what those questions are in the UK, representatives from 28 organizations involved in policy, together with scientists from 10 academic institutions, were asked to generate a list of questions from their organizations. 2 During a 2-day workshop the initial list of 1003 questions generated from consulting at least 654 policy makers and academics was used as a basis for (...) generating a short list of 100 questions of significant policy relevance. Short-listing was decided on the basis of the preferences of the representatives from the policy-led organizations. 3 The areas covered included most major issues of environmental concern in the UK, including agriculture, marine fisheries, climate change, ecosystem function and land management. 4 The most striking outcome was the preference for general questions rather than narrow ones. The reason is that policy is driven by broad issues rather than specific ones. In contrast, scientists are frequently best equipped to answer specific questions. This means that it may be necessary to extract the underpinning specific question before researchers can proceed. 5 Synthesis and applications. Greater communication between policy makers and scientists is required in order to ensure that applied ecologists are dealing with issues in a way that can feed into policy. It is particularly important that applied ecologists emphasize the generic value of their work wherever possible. (shrink)

We discuss the role of perceptron (or threshold) connectives in the context of Description Logic, and in particular their possible use as a bridge between statistical learning of models from data and logical reasoning over knowledge bases. We prove that such connectives can be added to the language of most forms of Description Logic without increasing the complexity of the corresponding inference problem. We show, with a practical example over the Gene Ontology, how even simple instances of perceptron connectives are (...) expressive enough to represent learned, complex concepts derived from real use cases. This opens up the possibility to import concepts learnt from data into existing ontologies. (shrink)

We introduce and discuss a knowledge-driven distillation approach to explaining black-box models by means of two kinds of interpretable models. The first is perceptron (or threshold) connectives, which enrich knowledge representation languages such as Description Logics with linear operators that serve as a bridge between statistical learning and logical reasoning. The second is Trepan Reloaded, an ap- proach that builds post-hoc explanations of black-box classifiers in the form of decision trees enhanced by domain knowledge. Our aim is, firstly, to target (...) a model-agnostic distillation approach exemplified with these two frameworks, secondly, to study how these two frameworks interact on a theoretical level, and, thirdly, to investigate use-cases in ML and AI in a comparative manner. Specifically, we envision that user-studies will help determine human understandability of explanations generated using these two frameworks. (shrink)

We present an algorithm for concept combination inspired and informed by the research in cognitive and experimental psychology. Dealing with concept combination requires, from a symbolic AI perspective, to cope with competitive needs: the need for compositionality and the need to account for typicality effects. Building on our previous work on weighted logic, the proposed algorithm can be seen as a step towards the management of both these needs. More precisely, following a proposal of Hampton [1], it combines two weighted (...) Description Logic formulas, each defining a concept, using the following general strategy. First it selects all the features needed for the combination, based on the logical distinc- tion between necessary and impossible features. Second, it determines the threshold and assigns new weights to the features of the combined concept trying to preserve the relevance and the necessity of the features. We illustrate how the algorithm works exploiting some paradigmatic examples discussed in the cognitive literature. (shrink)

Axiom weakening is a technique that allows for a fine-grained repair of inconsistent ontologies. Its main advantage is that it repairs on- tologies by making axioms less restrictive rather than by deleting them, employing the use of refinement operators. In this paper, we build on pre- viously introduced axiom weakening for ALC, and make it much more irresistible by extending its definitions to deal with SROIQ, the expressive and decidable description logic underlying OWL 2 DL. We extend the definitions of (...) refinement operator to deal with SROIQ constructs, in particular with role hierarchies, cardinality constraints and nominals, and illustrate its application. Finally, we discuss the problem of termi- nation of an iterated weakening procedure. (shrink)

Without unduly trying the patience of readers, I cannot respond to all their remarks, but I hope that in what follows I have replied to the most important of their comments on the arguments and conclusions of Valuing Health. Before I begin these replies, a brief synopsis of Valuing Health may be helpful to the reader. (shrink)

Regular musical activity as a complex multimodal lifestyle activity is proposed to be protective against age-related cognitive decline and Alzheimer’s disease. This cross-sectional study investigated the association and interplay between musical instrument playing during life, multi-domain cognitive abilities and brain morphology in older adults from the DZNE-Longitudinal Cognitive Impairment and Dementia Study study. Participants reporting having played a musical instrument across three life periods were compared to controls without a history of musical instrument playing, well-matched for reserve proxies of education, (...) intelligence, socioeconomic status and physical activity. Participants with musical activity outperformed controls in global cognition, working memory, executive functions, language, and visuospatial abilities, with no effects seen for learning and memory. The musically active group had greater gray matter volume in the somatosensory area, but did not differ from controls in higher-order frontal, temporal, or hippocampal volumes. However, the association between gray matter volume in distributed frontal-to-temporal regions and cognitive abilities was enhanced in participants with musical activity compared to controls. We show that playing a musical instrument during life relates to better late-life cognitive abilities and greater brain capacities in OA. Musical activity may serve as a multimodal enrichment strategy that could help preserve cognitive and brain health in late life. Longitudinal and interventional studies are needed to support this notion. (shrink)

The immediate occasion for this special issue was Christia Mercer’s influential paper “The Contextualist Revolution in Early Modern Philosophy”. In her paper, Mercer clearly demarcates two methodologies of the history of early modern philosophy. She argues that there has been a silent contextualist revolution in the past decades, and the reconstructivist methodology has been abandoned. One can easily get the impression that ‘reconstructivist’ has become a pejorative label that everyone outright rejects. Mercer’s examples of reconstructivist historians of philosophy are deceased (...) (P. F. Strawson, Margaret J. Osler, Richard Watson, and Bernard Williams), anonymous (the fans of philosopher* mentioned by Lisa Downing), or authors whose more recent work followed a contextualist methodology (Jonathan Bennett). The reconstructivist camp seems to have turned into a shadowy group, largely extinct by now, not unlike the Death Eaters in the fictional universe of Harry Potter. There are some figures who previously belonged to this group, but they have since reformed their ways – or so it seems. Sometimes it is rumoured that certain people may still have secret allegiance to it, but no one dares to fly its banner openly. We decided to create this special issue because we believe that reconstructivist methodology does not deserve this shadowy existence. (shrink)

My partner loves the experiences she gets from eating olives. I, on the other hand, hate the experiences I get from eating olives. We differ in tastes. But how exactly do we differ? In particular: do our taste experiences differ phenomenologically—that is, do my olive-experiences feel different than my partner’s olive-experiences? Some philosophers have assumed that the answer is “no,” and have advanced important arguments which turn on this assumption. I argue that, contrary to what these philosophers assume, ordinary taste (...) differences do involve differences in phenomenology. My olive-experiences feel different than my partner’s olive-experiences. I argue for this phenomenal thesis in stages. First, I argue that there is a link between our attitudes and our pleasures; second, I argue that there is a link between our pleasures and our phenomenology. Together, my conclusions link our attitudes and phenomenology in a way that vindicates the phenomenal thesis. Along the way, I fend off various worries about what the phenomenal thesis might entail. I show that it does not entail any form if radical subjectivism, nor does it entail that there is a “distinctive feeling of pleasure.” I close by considering how opponents of the phenomenal thesis might retreat to a weaker thesis: one which concerns extraordinary taste differences, as opposed to ordinary taste differences. I argue that there are no obviously sound arguments for even this weaker thesis, which should make us all the more confident in the phenomenal thesis. (shrink)

In his 2015 book, Valuing Health, the philosopher, Daniel Hausman, in referring to experienced utility maximization, touches on the question of whether people accept, and ought to accept, the assumption of health maximization vis-à-vis their own lives. This essay introduces Hausman’s arguments on experienced utility, before outlining the intellectual catalyst for the renewed interest in the maximization of experienced utility as an appropriate ethical rule; namely, the literature that arose in the 1990s that demonstrated that due to the so-called (...) gestalt characteristics, an individual’s retrospective and prospective assessments of an event—i.e. the remembered and decision utilities associated with that event—often systematically differ from the utility that he/she experiences or can reasonably expect to experience during the same event. The essay then touches upon some of the implications that this debate has on assuming that the maximization of quality-adjusted life years is the best way to judge the relative worth of different health profiles. To conclude, it is argued that, although contextual, it is sometimes important to consider in the policy discourse the apparent effects of the gestalt characteristics on remembered and decision utility.

Nietzsche has the reputation of being a virulent misogynist, so why are feminists interested in his philosophy? The essays in this volume provide answers to this question from a variety of feminist perspectives. The organization of the volume into two sets of essays, "Nietzsche's Use of Woman" and "Feminists' Use of Nietzsche," reflects the two general approaches taken to the issue of Nietzsche and woman. First, many debates have focused on how to interpret Nietzsche's remarks about women and femininity. Are (...) all of Nietzsche's comments to be read literally, or is he being ironic, perhaps even parodying and subverting stereotypes about women? Second, is his philosophy useful to feminist theory? Can we separate his philosophy from his seemingly derogatory remarks about women? Can feminists use his criticisms of truth, objectivity, reason, and the autonomous subject to challenge the exclusion of women from the history of philosophy? Some view his critiques of dualism and essentialism as well as his perspectivism and social constructivism as adumbrating later feminist positions. Others find troubling his privileging of masculinity and paradigms of domination; they see Nietzsche's sexual dualism as countering otherwise transgressive themes. Contributors are Debra Bergoffen, Maudmarie Clark, Daniel Conway, Jacques Derrida, Jean Graybeal, Kathleen Higgins, Luce Irigaray, Sarah Kofman, Tamsin Lorraine, Kelly Oliver, David Owen, Marilyn Pearsall, Ofelia Schutte, Linda Singer, Lynne Tirrell, and Kathleen Wininger.

In the ninth book of his Ἀτθίς the Athenian historian and religious expert Philochorus related an omen about which he had himself been consulted in the late fourth centuryb.c.e.(FGrHist328 F 67).When this year was done and the next was beginning, there occurred on the Acropolis the following prodigy: a female dog, having entered the temple of Athena Polias and made its way into the Pandroseion, got up on the altar of Zeus Herkeios, which is under the olive tree, and lay (...) down. It is an ancestral custom among the Athenians that no dog go up on the Acropolis. Around the same time, a star was evident for a while even in the daytime sky, when the sun was out and the weather was clear. And when we were asked about what the portent and the phenomenon meant, we said that both predicted the return of the exiles and that this would happen not as a result of a political change but rather in the existingpoliteia. And this interpretation actually came to pass. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:236 REMEMBERING THE PAST In his recent article "'Lively' Memory and 'Past' Memory," Oliver Johnson argues that the remarks in Treatise I. iii. 5 entail that Hume rejects all mnemonic knowledge of the past and that "we must drop the concept of the past, as it is ordinarily understood as something that once existed, from our account of memory." While I shall grant that Hume could claim no (...) knowledge of the past, I do not believe Johnson has shown that Hume rejects the past from his account of memory. In this paper I argue that Johnson misconstrues the relationship between Hume's two 'criteria' for distinguishing between ideas of memory and ideas of the imagination. I also show that if Johnson's account were correct, much of Hume's philosophy would be incoherent. Johnson begins by claiming that in Treatise I.i.3, Hume introduces two criteria for distinguishing between ideas of the memory and ideas of the imagination, namely, a criterion based on the greater force and liveliness of the idea of memory vis-a-vis the idea of imagination ('lively' memory) and a criterion based on the correspondence of the idea of memory to the impression from which it was derived ('past' memory). After commenting that these criteria follow one's common sense beliefs regarding memory (LMPM 345-346), Johnson suggests that Hume came to realize that there is a problem with his initial characterization of the distinction. He sets the problem in the form of a question: How do we go about distinguishing a memory-idea from an imagination idea in practice? Or, to sharpen the problem. How are we able to tell when we are really remembering some past 237 event instead of only imagining that we remember it? The answer to this question would seem to be simple. Since we have at our disposal two marks by which to distinguish memoryideas from imagination-ideas, all that we need to do is to determine whether the idea in question satisfies one of them. If it satisfies either, it is a memory-idea; if it satisfies neither, it must be an imaginationidea. Furthermore, since every memory-idea satisfies both criteria, it should be immaterial to which we appeal in making our test. (LMPM 346) Johnson goes on to show that in Treatise I. iii. 5 Hume claims that the criterion for past memory "is not sufficient to distinguish them [ideas of the memory from ideas of the imagination] in their operation, or make us show the one from the other; it being impossible to recai the past impressions, in order to compare them with our present ideas, and see whether their arrangement be exactly similar," which he takes to mark Hume's rejection of the criterion of past memory (LMPM 347). If a criterion is a principle that can be used to divide a class of objects into two subclasses without remainder, then, as Johnson presents them, both of Hume's 'criteria' are inadequate because each is too broad. The 'criterion' for past memory is concerned with the truth of an idea (cf. T 448 and 458), and, as such, it is equally applicable to ideas of memory and the imagination. For example, a historian 's reconstruction of a past event might be true, but the reconstruction is certainly an idea of the imagination, not an idea of the memory. Similarly, the 'criterion' for lively memory ('force and vivacity') is used to distinguish impressions from ideas (T 1) and beliefs regarding events of any temp- 238 oral location from ideas that are not believed (T 96) as well as ideas of the memory from ideas of the imagination. Thus, neither 'criterion' can singularly mark the distinction between ideas of the memory and ideas of the imagination. But if there is a problem with inadequate criteria, it is not clear that the problem is Hume's, for Hume did not claim that the 'criteria' can operate independently of one another. In Treatise I.i.3, Hume first discusses the 'criterion' for lively memory (T 8-9), and then he indicates that "There is another difference betwixt these two kinds of ideas, which is no less evident," viz.. that...

This book starts with the proposition that digital media invite play and indeed need to be played by their everyday users. Play is probably one of the most visible and powerful ways to appropriate the digital world. The diverse, emerging practices of digital media appear to be essentially playful: Users are involved and active, produce form and content, spread, exchange and consume it, take risks, are conscious of their own goals and the possibilities of achieving them, are skilled and know (...) how to acquire more skills. They share a perspective of can-do, a curiosity of what happens next? Play can be observed in social, economic, political, artistic, educational and criminal contexts and endeavours. It is employed as a strategy, for tacit or open resistance, as a method and productive practice, and something people do for fun. The book aims to define a particular contemporary attitude, a playful approach to media. It identifies some common ground and key principles in this novel terrain. Instead of looking at play and how it branches into different disciplines like business and education, the phenomenon of play in digital media is approached unconstrained by disciplinary boundaries. The contributions in this book provide a glimpse of a playful technological revolution that is a joyful celebration of possibilities that new media afford. This book is not a practical guide on how to hack a system or to pirate music, but provides critical insights into the unintended, artistic, fun, subversive, and sometimes dodgy applications of digital media. Contributions from Chris Crawford, Mathias Fuchs, Rilla Khaled, Sybille Lammes, Eva and Franco Mattes, Florian 'Floyd' Mueller, Michael Nitsche, Julian Oliver, and others cover and address topics such as reflective game design, identity and people's engagement in online media, conflicts and challenging opportunities for play, playing with cartographical interfaces, player-emergent production practices, the re-purposing of data, game creation as an educational approach, the ludification of society, the creation of meaning within and without play, the internalisation and subversion of roles through play, and the boundaries of play.

(LMPM 346) Johnson goes on to show that in Treatise I. iii. 5 Hume claims that the criterion for past memory "is not sufficient to distinguish them [ideas of the memory from ideas of the imagination] in their operation, or make us show the one from the other; it being impossible to recai the past impressions, in order to compare them with our present ideas, and see whether their arrangement be exactly similar," which he takes to mark Hume's rejection of the criterion of past memory (LMPM 347). If a criterion is a principle that can be used to divide a class of objects into two subclasses without remainder, then, as Johnson presents them, both of Hume's 'criteria' are inadequate because each is too broad. The 'criterion' for past memory is concerned with the truth of an idea (cf. T 448 and 458), and, as such, it is equally applicable to ideas of memory and the imagination. For example, a historian 's reconstruction of a past event might be true, but the reconstruction is certainly an idea of the imagination, not an idea of the memory. Similarly, the 'criterion' for lively memory ('force and vivacity') is used to distinguish impressions from ideas (T 1) and beliefs regarding events of any temp- 238 oral location from ideas that are not believed (T 96) as well as ideas of the memory from ideas of the imagination. Thus, neither 'criterion' can singularly mark the distinction between ideas of the memory and ideas of the imagination. But if there is a problem with inadequate criteria, it is not clear that the problem is Hume's, for Hume did not claim that the 'criteria' can operate independently of one another. In Treatise I.i.3, Hume first discusses the 'criterion' for lively memory (T 8-9), and then he indicates that "There is another difference betwixt these two kinds of ideas, which is no less evident," viz.. that...
