The search for a quantum theory of the gravitational field is one of the great open problems in theoretical physics. This book presents a self-contained discussion of the concepts, methods and applications that can be expected in such a theory. The two main approaches to its construction - the direct quantisation of Einstein's general theory of relativity and string theory - are covered. Whereas the first attempts to construct a viable theory for the gravitational field alone, string theory assumes that (...) a quantum theory of gravity will be achieved only through a unification of all the interactions. However, both employ the general method of quantisation of constrained systems, which is described together with illustrative examples relevant for quantum gravity. There is a detailed presentation of the main approaches employed in quantum general relativity: path-integral quantisation, the background-field method and canonical quantum gravity in the metric, connection and loop formulations. The discussion of string theory centres around its quantum-gravitational aspects and the comparison with quantum general relativity. Physical applications discussed at length include the quantisation of black holes, quantum cosmology, the indications of a discrete structure of spacetime, and the origin of irreversibility. This book will be of interest to researchers and students working in relativity and gravitation, cosmology, quantum field theory and related topics. It will also be of interest to mathematicians and philosophers of science. (shrink)

The nature of attention is one of the oldest and most central problems in psychology. A huge amount of research has been produced on this subject in the last half century, especially on attention in the visual modality, but a general explanation has remained elusive. Many still view attention research as a field that is fundamentally fragmented. This book takes a different perspective and presents a unified theory of visual attention: the TVA model. The TVA model explains the many aspects (...) of visual attention by just two mechanisms for selection of information: filtering and pigeonholing. These mechanisms are described in a set of simple equations, which allow TVA to mathematically model a large number of classical results in the attention literature. The theory explains psychological and neuroscientific findings by the same equations; TVA is a complete theory of visual attention, linking mind and brain. Aimed at advanced students and professional researchers, Principles of Visual Attention contains a detailed review of the most important research done on attention in vision, spanning cognitive psychology, brain imaging, patient studies, and recordings from single cells in the visual cortex. The book explains the TVA model and shows how it accounts for attentional effects observed across all the research areas described. Principles of Visual Attention offers a uniquely integrated view on a central topic in cognitive neuroscience. (shrink)

The ancient virtue of practical wisdom has lately been enjoying a remarkable renaissance in management literature. The purpose of this article is to add clarity and bring synergy to the interdisciplinary debate. In a review of the wide-ranging field of the existing literature from a philosophical, theological, psychological, and managerial perspective, we show that, although different in terms of approach, methodologies, and justification, the distinct traditions of research on practical wisdom can indeed complement one another. We suggest a conciliatory conception (...) of the various features of practical wisdom in management. This we take as a point of departure for a discussion of the significant implications of the subject for the theory and practice of management and for the direction of further research in the field.

In summary, the creation and maintenance of the Wistar Rats as standardized animals can be attributed to the breeding work of Helen Dean King, coupled with the management and husbandry methods of Milton Greenman and Louise Duhring, and with supporting documentation provided by Henry Donaldson. The widespread use of the Wistar Rats, however, is a function of the ingenuity of Milton Greenman who saw in them a way for a small institution to provide service to science. Greenman's rhetoric, as captured (...) in his Director's Reports, prepared annually from 1905 until his death in 1937, shows that he was unusually sensitive to his times and to the economics of science and of society. In the era when biology was being defined, he recognized in the rat the potential to be a living analog to the pure chemicals that legitimated experimental science. From management literature he extracted the ideals of uniformity of product, standards of quality, and efficiency of production, applying them to scientific practice to generate an animal model that thrives as standard equipment in laboratories throughout the world today.I will close with a quote from Frederick W. Taylor that is a cogent statement of the contribution to science and scientific progress made by standardized tools and their creators. Equating the surgeon and the workman, Taylor wrote: [He is given] the finest implements, each one of which has been the subject of special study and development ... [and] the very best knowledge of his predecessors; and, provided with standard implements and methods which represent the best knowledge of the world up to date, he is able to use his own originality and ingenuity to make real additions to the world's knowledge, instead of reinventing things which are old.Standardized tools, whether surgeons' implements or laboratory-bred rats, are one of the vehicles for carrying scientific knowledge forward from generation to generation. In this sense, Greenman's Wistar Rats have done their job, in his words, of “providing service to science.”. (shrink)

The Formalist tradition in late-scholastic philosophy has gone unnoticed in standard historiography. This article’s overall objective is to add the Formalist tradition to what we know about Renaissance philosophy. I first show how the Formalist tradition was born out of some innovative considerations of hierarchies of distinctions in the wake of the Franciscan John Duns Scotus’s teaching on the formal distinction in the beginning of the fourteenth century (especially Francis of Meyronnes’s model of four distinctions and Petrus Thomae’s more elaborate (...) doctrine of seven kinds of distinctions). I then trace how Formalist literature developed from being an exclusively Franciscan affair to becoming a much more widespread phenomenon. Thus, from the decades up to 1500 and onwards, authors from various late-scholastic schools (Thomism, Lullism, Averroism, and others) produced Formalist literature, i.e., treatises on multiple kinds of distinctions. I highlight particularly how one Franciscan philosopher of the sixteenth century, Jean Du Douet, proposed to view the Formalist preoccupation with distinctions as a discipline in its own right, a proper scientia formalitatum. I finally argue that while this proposal met with dismissive reactions, Du Douet’s idea does in fact reflect the role Formalism played in the scholastic curriculum in the late sixteenth century, at least in Franciscan milieus.

In business ethics journals, Kant’s ethics is often portrayed as overly formalistic, devoid of substantial content, and without regard for the consequences of actions or questions of character. Hence, virtue ethicists ride happily to the rescue, offering to replace or complement Kant’s theory with their own. Before such efforts are undertaken, however, one should recognize that Kant himself wrote a “virtue theory” (Tugendlehre), wherein he discussed the questions of character as well as the teleological nature of human action. Numerous Kant (...) scholars argue that Kant already erected precisely the kind of integrative moral architecture that some of his modern interpreters (while aiming to supersede him) wish to construct. For business ethics, this divergence of scholarly opinion is of crucial importance. It shows first that the standard portrayals of Kant’s ethics in business ethics textbooks—as rigidly deontological, narrowly individualistic, and hence unsuitable for the specific demands of corporate agency—might have to be revised. Second, discussions in the business ethics literature on stakeholder-engagement and managerial decision-making likewise stand to gain from a more nuanced picture of Kant’s moral philosophy. Third, a reassessment of Kant’s ethics with regard to questions of personal character and moral sentiments might also lead to a more favorable view of the relevance of his ethics for managerial practice. Last, but not least, the many current attempts to reconcile Kant’s freedom-oriented philosophy with virtue theories stand to benefit considerably from a better understanding of how Kant himself conceived of one such synthesis between the formal and substantial aspects of morality. This, ultimately, could lead to an important overlapping consensus in the academic literature as to the role and relevance of virtuous conduct in business. (shrink)

It is argued that the notion of Umwelt is relevant for contemporary discussions within theoretical biology, biosemiotics, the study of Artificial Life, Autonomous Systems Research and philosophy of biology. Focus is put on the question of whether an artificial creature can have a phenomenal world in the sense of the Umwelt notion of Jakob von Uexküll, one of the founding figures of biosemiotics. Rather than vitalism, Uexküll's position can be interpreted as a version of qualitative organicism. A historical sketch of (...) Autonomous Systems Research (ASR) is presented to show its theoretical roots and fruitful opposition to traditional AI style robotics. It is argued that these artificial systems are only partly 'situated' because they do not in the full sense of the word experience an Umwelt. A deeper understanding of truly situated autonomous systems as being a kind of complex selforganizing semiotic agents with emergent qualitative properties must be gained, not only from the broad field of theoretical biology, but also from the perspective of biosemiotics in the Uexküll tradition. The paper is thus an investigation of a new notion of autonomy that includes a qualitative aspect of the organism. This indicates that the Umwelt concept is not reducible to purely functional notions. (shrink)

Computer simulations and experiments share many important features. One way of explaining the similarities is to say that computer simulations just are experiments. This claim is quite popular in the literature. The aim of this paper is to argue against the claim and to develop an alternative explanation of why computer simulations resemble experiments. To this purpose, experiment is characterized in terms of an intervention on a system and of the observation of the reaction. Thus, if computer simulations are experiments, (...) either the computer hardware or the target system must be intervened on and observed. I argue against the first option using the non-observation argument, among others. The second option is excluded by e.g. the over-control argument, which stresses epistemological differences between experiments and simulations. To account for the similarities between experiments and computer simulations, I propose to say that computer simulations can model possible experiments and do in fact often do so. (shrink)

If cosmology is to obtain knowledge about the whole universe, it faces an underdetermination problem: Alternative space-time models are compatible with our evidence. The problem can be avoided though, if there are good reasons to adopt the Cosmological Principle (CP), because, assuming the principle, one can confine oneself to the small class of homogeneous and isotropic space-time models. The aim of this paper is to ask whether there are good reasons to adopt the Cosmological Principle in order to avoid underdetermination (...) in cosmology. Various strategies to justify the CP are examined. For instance, arguments to the effect that the truth of the CP follows generically from a large set of initial conditions; an inference to the best explanation; and an inductive strategy are assessed. I conclude that a convincing justification of the CP has not yet been established, but this claim is contingent on a number of results that may have to be revised in the future. (shrink)

Reflective equilibrium (RE) is often regarded as a powerful method in ethics, logic, and even philosophy in general. Despite this popularity, characterizations of the method have been fairly vague and unspecific so far. It thus may be doubted whether RE is more than a jumble of appealing but ultimately sketchy ideas that cannot be spelled out consistently. In this paper, we dispel such doubts by devising a formal model of RE. The model contains as components the agent’s commitments and a (...) theory that tries to systematize the commitments. It yields a precise picture of how the commitments and the theory are adjusted to each other. The model differentiates between equilibrium as a target state and the dynamic equilibration process. First solutions to the model, obtained by computer simulation, show that the method allows for consistent specification and that the model’s implications are plausible in view of expectations on RE. In particular, the mutual adjustment of commitments and theory can improve one’s commitments, as proponents of RE have suggested. We argue that our model is fruitful not only because it points to issues that need to be dealt with for a better understanding of RE, but also because it provides the means to address these issues.

The evolutionary emergence of biological processes in organisms with inner, qualitative aspects has not been explained in any sufficient way by neurobiology, nor by the traditional neo-Darwinian paradigm — natural selection would appear to work just as well on insentient zombies (with the right behavioral input-output relations) as on real sentient animals. In consciousness studies one talks about the ‘hard problem’ of qualia. In this paper I sketch a set of principles about sign action, causality and emergent evolution. On the (...) basis of these principles, I characterize a concept of cause that would allow for a naturalistic explanation of the origin of consciousness. The suggested account of causation also turns the ‘hard problem’ of qualia into the easier problem of relating experimental biology to experiential biology. (shrink)

The ontological status of esse cognitum was at the center of complex debates throughout the Scotist tradition (Alnwick vs. Aesculo, Mastri vs. Punch). This article investigates the Scotist Angelo Volpe’s discussion of esse cognitum enjoyed by possible creatures in the divine intellect. Volpe responds to two religious warnings, one against assuming any eternal real being for merely possible creatures, and a second against depriving God’s eternal knowledge of a corresponding object, since that would endanger this knowledge itself. Volpe opts for (...) a solution that allows possible creatures the status of beings of reason (entia rationis) due to their own ontological merit, and the status of real beings (entia realia) due to God’s knowing that they as possibles are not in opposition to real existence. He rejects the view that esse cognitum is a kind of being that holds a middle position between real being and being of reason. Volpe’s historical significance is emphasized. (shrink)

One point that definitions of art experience disagree about is whether this kind of experience is qualitatively different from experiences related to ordinary objects and everyday contexts. Here, we follow an ecological approach assuming that art experience has its own specific quality that is, not least, determined by typical contexts of art presentation. Practically, we systematically observe typical phenomena of experiencing art in ecologically valid or real-world settings such as museum contexts. Based on evidences gained in this manner, we emulate (...) and implement essential properties of ecological contexts (e.g., free choice of viewing distance and time, large scale of artworks and exhibition-like context) in controlled laboratory experiments. We found, for instance, that for large scale paintings by Pollock and Rothko preferred viewing distances as well as distances inducing most intense art experiences including Aesthetic Aha insights were much larger than typical viewing distances realized in lab studies. Following Carbon’s (2019) terminology of measurement strategies of art experience, the combined use of “Path #1” (real-world context) and “Path #2” (mildly controlled, still ecologically valid settings and contexts), enables us to understand and investigate much closer what is really happening when people experience art.

In his Critique of Pure Reason, in the chapter on the antinomy of pure reason, Kant not only argues that aprioristic cosmology is doomed to failure; he also implies that empirical knowledge about the universe is impossible. Today, such a negative verdict about the possibility of cosmological knowledge seems implausible because physical cosmology has made substantial progress. In particular, the spatiotemporal extension of the universe now seems a matter of empirical investigation in which models figure centrally. But I think it (...) is worth considering the possibility that Kant got something right and that he offers insights that can help us to better understand problems in present-day cosmology. In this article, I explore a striking coincidence: according to both Kant and current wisdom, cosmology faces a serious underdetermination problem regarding the spatiotemporal extension of the world. As a closer analysis reveals, however, Kant and modern cosmology differ on the reasons why underdetermination arises. In current cosmology, underdetermination follows from laws that are knowable a posteriori, and not only from the very idea of cosmological knowledge, as Kant would have it. This suggests that the current underdetermination problem is not fully a Kantian one. (shrink)

Increases of absolute brain size during evolution reinforced stronger structuring of brain connectivity. One consequence is the hierarchical cluster structure of neural systems that combines predominantly short, but not strictly minimal, wiring with short processing pathways. Principles of “large equals well-connected” and “minimal wiring” do not completely account for observed patterns of brain connectivity. A structural model promises better predictions.

Healthcare organizations and workers are under pressure to produce increasingly complete and accurate data for multiple data-intensive endeavors. However, little research has examined the emerging occupations arising to carry out the data work necessary to produce “improved” data sets, or the specific work activities of these emerging data occupations. We describe the work of Clinical Documentation Integrity Specialists, an emerging occupation that focuses on improving clinical documentation to produce more detailed and accurate administrative datasets crucial for evolving data-intensive forms of (...) healthcare accountability, management, and research. Using ethnographic methods, we describe the core of CDIS’ work as a translation practice in which the language, interests, and concerns of clinicians and clinical documentation are translated via real-time “nudging” and ongoing education of clinicians into the language, interests, and concerns of medical coders, structured administrative datasets, and the various stakeholders of these datasets. Further, we show how the institutional context of CDIS’ work shapes the occupational virtues that guide CDIS’ translation practice, including financial reimbursement, quality measures, clinical accuracy, and protecting clinician’s time. Despite the existence of these multiple virtues, financial reimbursement is the most prominent virtue guiding CDIS’ limited attention. Thus, overall clinical documentation is “improved” in specific, partial ways. This research provides one of the first studies of the emergent data work occupations arising in the wake of digitization and big data opportunities, and shows how local data settings shape large scale data in specific ways and thus may influence outcomes of analyses based on such data.

Statistical physicists assume a probability distribution over micro-states to explain thermodynamic behavior. The question of this paper is whether these probabilities are part of a best system and can thus be interpreted as Humean chances. I consider two Boltzmannian accounts of the Second Law, viz. a globalist and a localist one. In both cases, the probabilities fail to be chances because they have rivals that are roughly equally good. I conclude with the diagnosis that well-defined micro-probabilities under-estimate the robust character (...) of explanations in statistical physics. (shrink)

2024 marks the 400th anniversary of the publication of Theodor Smising’s giant volume De Deo Uno (printed in Antwerp in 1624), which was soon followed by a second volume, De Deo Trino (printed in Antwerp in 1626). Smising’s work was the first printed output of what developed into a specific tradition within early modern thought, the Louvain tradition of Scotism, itself but one part of the broad Scotist tradition that build upon the thought of John Duns Scotus (ca. 1266–1308). This (...) Louvain tradition was primarily based in the Franciscan Convent of the Holy Trinity in the famous university town. The convent itself was much older, dating back to around 1230, when the Franciscan Order was in its very beginnings and long before the University of Louvain was founded (in 1425). In 1607 a second Franciscan Convent was founded in Louvain, St. Anthony’s College, one of a series of convents established by the Irish Franciscans as a result of their persecution in their homeland by the English Protestant rulers. The Irish Franciscans in Louvain, and in their other convents on the European continent, also cultivated the intellectual heritage of Duns Scotus, editing and commenting on his works and writing new works “ad mentem Scoti.” Both of the Franciscan convents in Louvain were closed in the turmoil after the French Revolution. The buildings of St. Anthony’s College still exist, whereas the older “Minderbroedersklooster” (on our exhibition poster) completely vanished from the cityscape. In recent decades, the Maurits Sabbe Library has acquired a large fund of Franciscan books, mostly from various houses of the Franciscan Order in Belgium that have closed their doors. Our exhibition “Scotism Made in Louvain – The Scholastic Culture of the Franciscans in Belgium” explores this material, complemented by material from the KU Leuven Central Library’s Special Collections and two manuscripts from the archives of KADOC (Documentatie- en Onderzoekscentrum voor Religie, Cultuur en Samenleving). The exhibition tells the story of a significant local scholarly tradition which is placed in the context of the broader Scotist tradition of the Early Modern Period. Whereas Scholasticism as such is often seen as an exclusively medieval phenomenon, our exhibition highlights one important aspect of early modern scholastic culture. The three brief articles included in this catalogue provide an introduction to John Duns Scotus’s thought, investigate the institutional background of Louvain Scotism, and explore some of the most important aspects of the scholastic output of the Franciscans in Louvain. The numbers attached to the images refer to the annotated list of all exhibits. A virtual exhibition with additional photo material will accompany, and last beyond, the library exhibition. (shrink)

Narrative desire, according to philosopher Adriana Cavarero, is the desire for one’s own history. What can semiotics of literature say about friendship as a dialogic phenomenon and the narrative desire for personal-historical knowledge in friendship, and how is this kind of knowledge semiotically different from knowledge achieved by science and scholarship? As an interpersonal relation, friendship is discussed here from the perspective of semiotics and precarious knowledge, i.e., as a historically contingent relation that can be semiotically modelled (represented by mappings (...) that are to some degree cognitively adequate and emotionally convincing) both within fiction literature and academic disciplines such as philosophy, anthropology, sociology, psychology and history. Friendship as a complex phenomenon has recently received increased attention from many distinct theoretical perspectives and disciplines. There are forms of “hidden interdisciplinarity” in friendship studies, as well as mono- and multidisciplinary approaches. A good case in point is recent discussions on how well a novel can model friendship. The opposite claims of philosopher Alexander Nehamas and literary critic Gregory Jusdanis on the adequacy of the novel for describing friendship will be discussed. By considering ‘The Neapolitan Novels’ by Elena Ferrante, depicting a close, difficult, life-long friendship between two women and its concerns with precarious dialogues and knowledge (like what the two very different persons really know about each other), as well as recent scholarship on Ferrante’s work, I show how her novels are not just inspired by, but also indirectly a critical comment upon the work on narrative friendship by Cavarero. Friends differ, and some of their differences constitute a challenge for universal models of friendship and narrative desire. Furthermore, Ferrante’s novels add a challenging complexity to a central insight analysed by Santaella as Peirce’s dialogism – that the action of signs is not merely individual but social, and that this applies as well to the person, whose thoughts are what she is “saying to that other self that is just coming into life in the flow of time” (CP 5.421; Santaella 2004: 132). The novels can be seen as modelling the very genesis of that dialogic self in the precarious process of finding a balance between dependency and autonomy between the friends. (shrink)

Calls for interdisciplinarity in the humanities often presume the existence of disciplines as separate academic fields, with research collaboration framed as a crossing of the borders between separate areas of knowledge. By way of two case studies and a comparative approach called borderology, the chapter questions such a notion and investigates other aspects of interdisciplinary work as practised by researchers in the humanities and the social sciences. First, the rich work on modern love by sociologist Eva Illouz, illustrating a form (...) of intrinsic interdisciplinarity, is analyzed. Second, recent work within friendship studies is compared, and borderology is used to shed light upon friendship both as a real phenomenon and as a cluster of concepts invoked and investigated by different disciplines. These examples may help policy makers appreciate one of the ways in which the humanities are always already interdisciplinary. (shrink)

Traditional notions of translation (TN or ‘narrow translation’) have had a primary focus on text translation and how meaning can be preserved. This chapter employs an alternative semiotic understanding of translation (TS or ‘semiotic translation’), as suggested by Kobus Marais, to demonstrate how it can be used to study inter-epoch changes in norm-directed practices and their conceptualizations, cross-cultural developments and interdisciplinary translations of concepts used to describe them. Friendship practices and their theoretical descriptions are used as a case to show (...) the need for alternative understandings of translation processes. TS occurs not only when texts are taken as signs of complex phenomena but also when a mode of life and the sociolinguistic practice of one generation or culture is interpreted and changed by its inheritors. To develop TS as a general and theoretically more satisfying model, we investigate some of the processes involved in the inter-epoch conceptualizations and cross-cultural developments of friendship. Claiming that different friendship studies all contribute to knowledge of some aspects of ‘the same’ phenomenon demands the possibility of translations of ‘friendship’ as a word, concept, practice, interpersonal relationship, social bond, ideal, form of love, normative constraint, power relation or any other terms that have been used to characterize its phenomenology and dynamics. Analysing TS translations of friendship across epochs (from Confucius and Aristotle through the following eras, up to modernity), cultures (worldwide) and languages demonstrates how the perspective of TS helps us grasp ancient texts, their translations and cross-cultural friendship performances better without forcing upon the material our late-modern perspectives and norms. It is suggested that frames (from artificial intelligence and philosophy of science) can be an analytic tool for studying TS processes. Finally, some challenges to be resolved in further research are outlined. (shrink)

The purpose of this article is to show how young people typically interact with technology. Young people take up modern technology and incorporate it in their everyday lives more rapidly and more unceremoniously than others. As they make use of technical artifacts, the everyday lives of young people change, as does their perception of society, because it is through the artifacts that relationships with others are organized. The significance of technology in young people’s everyday lives remains largely unexplored. This deficiency (...) clearly contrasts with an information society, the very basis of which is supposed to be the knowledge of its organizing principles. This article reports on recent findings of how clearly defined social relationships disintegrate because of new technologies and on how young people are challenged to put the applications that technology offers to them into new contexts. The idea is to make a subjectively important choice among the large variety of options given. It shows that technology is no longer result but rather experience oriented. One can foresee the considerable consequences not only for politics, education, and technology development but also for research done in the social sciences. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Scientia propter quid nobis—The Epistemic Independence of Metaphysics and Theology in the Quaestio de cognitione Dei attributed to Duns Scotus by Wouter GorisClaus A. AndersenGORIS, Wouter. Scientia propter quid nobis—The Epistemic Independence of Metaphysics and Theology in the Quaestio de cognitione Dei attributed to Duns Scotus. Münster: Aschendorff, 2022. viii + 296 pp. Paper, € 49.00The central claim of Wouter Goris's new book is that the Quaestio de (...) cognitione Dei traditionally (both in one late medieval manuscript and in some modern scholarship) attributed to John Duns Scotus not only is inauthentic but in fact represents an early reaction against Scotus's teaching on the scientific nature of metaphysics. The Quaestio in particular explores Scotus's distinction between a science "in itself" and one "for us" and, going beyond Scotus's own doctrine, shows how this distinction is applicable to metaphysics.The book is divided into three parts. Part 1 offers a critical edition of the Quaestio de cognitione Dei, which has hitherto been available in a plain transcription published by C. R. S. Harris in 1927. Harris's text was based on a single manuscript from the fifteenth century (Oxford, Merton College, Ms. 90); Goris bases his edition on a manuscript from the early fourteenth century (Assisi, Biblioteca Comunale, Ms. 172), one that does not attribute the text to Scotus. Goris highlights that the text has significant parallels in the prologue of John of Reading's Scriptum on the first book of the Sentences; there is presently not sufficient evidence for claiming that Reading is the author of the De cognitione Dei, but it does seem clear that either Reading or some other Franciscan friar relying on Reading's Scriptum authored the text between 1316 and 1325. The Quaestio itself consists of two articles. Two appendices to the edition document longer passages from Reading's Scriptum.Part 2 investigates the use of the distinction between a science in itself and one for us in Duns Scotus and some of the early Scotists. Scotus's doctrine developed over time. At Oxford Scotus taught that theology in se is about the divine essence in its particularity; theology for us is about the most perfect concept of God attainable for human beings by natural means, that is, the concept "infinite being." It falls to metaphysics to prove that there is such a kind of being. At Paris Scotus rather taught that both theology in se and theology for us are about the divine essence in its [End Page 549] particularity. The implication is that a strictly demonstrative science about God is possible for human beings in this present life, a knowledge of God that is completely independent of metaphysics. Goris argues that this shift in the view of theology explains the absence of Scotus's famous "twin doctrines" of the univocal concept of being and of being as the first adequate object of the intellect from his theological epistemology of the Parisian period. Not too surprisingly, in the wake of Scotus we find several authors grappling with the relationship between theology and metaphysics. The positions investigated by Goris vary considerably. Richard of Conington distinguishes between human metaphysical knowledge of being and God's own metaphysical knowledge of being; the latter represents a more perfect knowledge of both God himself and creatures as included under the concept of being. Francis of Marchia employs a distinction between a general metaphysics (about being as being) and a special metaphysics (about divine being), but on the level of science for us the special part of metaphysics is subordinated to the general one. Nicolas Bonetus, by contrast, advocates a sharp distinction between metaphysical knowledge of being and natural theology; he structures his metaphysics as a purely ontological discipline and treats natural theology as a separate science; Goris sees this reorganization as Bonetus's most decisive contribution to the history of metaphysics.Part 3 analyzes the fundamental doctrines defended in the Quaestio de cognitione Dei and compares them with those of Scotus and John of Reading. The first article of the Quaestio introduces two important distinctions, the first of which is between metaphysics in itself and metaphysics for us; these two... (shrink)

In contemporary computer simulations, particles attract each other and form clusters, cells interact, and agents communicate with one another. This is at least how computer simulations are commonly described. But how can we make sense of such talk? One answer is that the particles, cells, and agents inside simulations are digital artifacts, and thus real objects. In this paper, I cast doubt on this realist position by raising the question: To what objects does a simulation give rise, if it does (...) so at all? I tentatively suggest answers that try to determine what objects arise in computer simulations at both a fundamental and a higher level. However, closer analysis reveals that we run into underdetermination problems. Even for a single run of a simulation program, the acknowledged facts about the simulations often do not suffice to determine the objects and their properties uniquely. I suggest that, from an ontological perspective, it is more attractive to say that computer simulations involve computations, the results of which may then be interpreted in various ways. To make sense of talk about objects in simulations it is more attractive to develop a fictionalist account, or so I argue. (shrink)

Duns Scotus and Aquinas agree that whereas God comprehends Himself or even is his own comprehension, no creature can ever comprehend God. In the 17th century, the two Scotists Bartolomeo Mastri and Bonaventura Belluto discuss comprehension in their manual of philosophical psychology. Although they attempt to articulate a genuine Scotist doctrine on the subject, this article shows that they in fact defend a stance close to the one endorsed by contemporary scholastics outside the Scotist school. The article situates their discussion (...) within 17th-century scholasticism. The article furthermore highlights the theological motifs in Mastri and Belluto’s discussion of comprehension. Although they claim that their discussion does not transgress the limits of Aristotelian psychology, all of their arguments are theological in nature. From this I conclude that in this particular context our two Scotists clearly start out with a set of theological convictions, rather than with any particular philosophico-epistemological beliefs.

When posing the question "is artificial life possible?", our immediate answer is that on the one hand : of course it is - people make it, and indeed very interesting and even breathtaking structures have already been constructed, such as `aminats', self-reproducing patterns and the other things, we have seen already. In this sense we are forced to take artificial life as a fact (at least as a fact about a new branch of research), nearly in the same way that (...) the philosopher Kant took the theoretical physics of his days, Newtonian physics, as a matter of fact, and then asked: What are the conditions of possibility for this kind of theoretical science? On the other hand: The situation differs from Kant's. Artificial Life does not confront us with an analogy of theoretical mechanics within the field of biology. We face a curious situation: It is not obvious to the majority of biologists that Artificial Life is possible at all, at least in the purely computational sense of `software life'. Probably, most biologists would never call these artificial constructs `living'. Why not? Because the intuitive notions of life and living systems within biology implies, among other things, that living beings are a result of a long, ongoing evolutionary process that have created autonomous organisms, single-celled and multi-celled, that are highly organized, open (non-equilibrium), material thermodynamic systems based on metabolism and some kind of genetic information supported by macromolecules, that only metaphorically resemble a computer program. It is not that.. (shrink)

The strong version of Artificial Life claim that emergent computational patterns may not simply simulate life but realize the very phenomenon. This is one of several reasons why a definition of life is of interest. In this paper, it is argued that the received view of definitions of life in biology and philosophy is misleading. Generality cannot in general be dispensed with. Though criteria for adequacy of definitions are highly context-dependent, definitions of life are of a special nature, belonging to (...) what is here called ontodefinitions. Separate definitions of life fulfilling a set of relevant criteria exist and belong to distinct paradigms of theoretical biology. Emergence is implicit in these. The paper investigates if emergence entails 'downward causation' (several kinds are defined), and asks if computational models can represent higher orders of emergence. Finally, a comment is made on the role of Wittgenstein's philosophy in understanding the nature of explanation and definition in science. --- ### --- -/- Bibliographical note: Earlier versions of this paper were presented at the Princeton History of Science Workshop on "Growing Explanations", Princeton University, February 15, 1997; and at the meeting in the International Society for the History, Philosophy and Social Studies of Biology (ISHPSSB) in Seattle, USA, July 16-21, 1997.

The Cistercian Jaume Janer († after 1506) was the most prolific student of Pere Daguí, the first professor in the Lullist Studium on Majorca, and became himself, by royal privilege from the Crown of Aragon, the leader of a similar institution in Valencia. Janer’s and Daguí’s brand of Lullism embraced elements from Scotism. In particular, Janer in three of his works discussed the system of distinctions put forward by Peter Thomae, one of Duns Scotus’s early followers. This preoccupation with Scotist (...) distinction theory remained a doctrinal centerpiece of eclectic Lullism at least until the second half of the seventeenth century. (shrink)

This article is an account of an electronic discussion which took place between November 1995 and June 1996. A number of specialists in relevant research areas had been invited to take part in the discussion from the very beginning, and some were added later. Altogether 30 individuals subscribed to the list. The “target paper,” written by Allen Renear, was sent to the list on November 27, 1995. The target paper alone comprised 8,500 words. The ensuing discussion, to which 9 of (...) the members on the list made one or more individual contributions, comprises 30 entries of altogether 37,000 words. It is the function of this printed article to provide a brief summary and a key to the full electronic discussion which accompanies it. (shrink)

The increasing problem of bioinvasion (the mixing up of natural species characterising the planet's local ecosystems due to globalisation) is investigated as an example of an ecosemiotic problematic. One concern is the scarcity of scientific knowledge about long term ecological and evolutionary consequences of invading species. It is argued that a natural science conception of the ecology of bioinvasion should be supplemented with an ecosemiotic understanding of the significance of these problems in relation to human culture, the question of cultural (...) diversity, and what it means to be indigenous or foreign. Bioinvasion, extinction of native species, and overall decrease in biodiversity, may go along with decreased cultural diversity; as when the loss of local agricultural traditions lead to genetic erosion. There are possible ecosemiotic parallels between language extinction and species extinction, both being related to globalisation. It is argued that the case of bioinvasion reveals the existence of two kinds of ecosemiotic contingency, (1) evolutionary openended and partly random generation of new species and extinction of old ones; (2) the historicity of culture in general and "culture's nature" specifically in the demarcation of a set of landscapes characteristic to a particular nation and piece of human history.

Cosmological questions (e.g., how far the world extends and how it all began) have occupied humans for ages and given rise to numerous conjectures, both within and outside philosophy. To put to rest fruitless speculation, Kant argued that these questions move beyond the limits of human knowledge. This article begins with Kant’s doubts about cosmology and shows that his arguments presuppose unreasonably high standards on knowledge and unwarranted assumptions about space-time. As an analysis of the foundations of twentieth-century cosmology reveals, (...) other worries about the discipline can be avoided too if the universe is modeled using Einstein’s general theory of relativity. There is now strong observational support for one particular model. However, due to underdetermination problems, the big cosmological questions cannot be fully answered using this model either. This opens the space for more speculative proposals again (e.g., that the universe is only part of a huge multiverse). (shrink)

Is life a property of the material structure of a living system or an abstract form of organization that can be realized in other media; artificial as well as natural? One version of the Artificial Life research programme presumes, that one can separate the logical form of an organism from its material basis of construction, and that its capacity to live and reproduce is a property of the form, not the matter (Langton 1989). This seems to oppose the notion of (...) a cell within contemporary molecular biology, according to which "form" and "matter" do not represent separate realms. The information in a living cell is intimately bound to the properties of the material substrate. This condition may represent a restriction on the validity of formal theories of life. (shrink)

Die Philosophie des Barockscotismus war einerseits durch die rückwärtsgewandte Anknüpfung an den mittelalterlichen Denker Johannes Duns Scotus, andererseits durch die Anknüpfung an die Entwicklung in der zeitgenössischen Scholastik, vor allem der Jesuitenscholastik, geprägt. Welche Art von Metaphysik hat diese besondere philosophiehistorische Konstellation hervorgebracht? Um diese Frage zu beantworten, analysiert die vorliegende Arbeit das Metaphysikwerk des wichtigsten Repräsentanten des frühneuzeitlichen Scotismus, Bartholomaeus Mastrius (1602-1673); sie erschließt außerdem eine Vielzahl von kaum bis gar nicht erforschten Metaphysikwerken aus der Franziskanerscholastik des 17. und (...) 18. Jahrhunderts. Das eigenartige, erstaunliche Vielfalt einschließende Profil einer in Vergessenheit geratenen philosophischen Tradition wird deutlich. Durch den Fokus auf ein philosophiehistorisches Phänomen außerhalb des Mainstreams leistet die Arbeit einen Beitrag zu einer differenzierteren Sichtweise der intellektuellen Kultur der europäischen Frühmoderne. Baroque-age Scotist philosophy was, on the one hand, characterised by recourse to the Medieval thinker John Duns Scotus and, on the other hand, by an adaptation to trends in contemporary scholasticism, first of all that of the Jesuits. What kind of metaphysics did this particular constellation within the history of philosophy produce? In order to answer this question, the present book analyses the work on metaphysics by the most important representative of early modern Scotism, Bartolomeo Mastri (1602-1673). In addition, the book investigates a multitude of scarcely or never studied works on metaphysics from the Franciscan scholastic tradition of the 17th and 18th centuries. The peculiar profile of a forgotten philosophical tradition with its astonishing plurality becomes apparent. By focusing on a phenomenon from the history of philosophy outside the mainstream, this work contributes to a more differentiated view on the intellectual culture in early modern Europe. (shrink)

There were days in the 70s when studying a subject at university and participating in a cultural and social revolution seemed like one and the same thing. When you were studying something like biology there was nothing the least bit strange in the fact that `biomass' became political student slang for the mass of biology students who constantly had to be `mobilized' against the bourgeoisie's reactionary measures directed against the experimental Roskilde University, university Marxism, long student careers and other benefits (...) of the new society. And it seemed quite a matter of course that the biomass could not itself be a revolutionary subject, so it had to be mobilized from without, by the party or the `critical' avant-garde. I don't want to gloat over the romantic revolutionary naiveté of the period - plenty of others do that, although one is unlikely to understand history through irony and condemnation. But in this particular context the thought of the mobilizable mass came up again. Perhaps the very notion of masses - very generally - involves the idea that masses must be without a will of their own, or if they have one, that it is at any rate not very rational and must be given some..

A thorough distinction between explanatory and descriptive concepts reveals a radical explanatory and a trivial descriptive doctrine in current neuroscientific research. The explanatory approach examines the neuronal substrates of the mind, whereas the descriptive one deals only with its correlates.

Observation is described as that which is informationally linked to the observed with the help of its being characterized both internally and externally. The external characterization refers to what perception really is (exemplified by seeing) in the manner semantic externalism treats natural kinds. Observable predicates are treated as reducible to appearance behaviour thus characterized. Referring to this way of semantical reduction distinguishes cultures of knowledge from cultures which acknowledge linguistic utterances as truthmakers. Introductory Remarks Theories of the sciences have mainly (...) dealt with how observation confirms or disconfirms a hypothesis. The question why observation matters at all has hardly been dealt with. Instead of giving empirical evidence one could consider looking for evidence in books. Indeed, we use books in order to gain knowledge but in the sciences this is commonly justified for the reason that scientific books refer to formerly published empirical data utilized in current theories—because of their reference to observation. Imagine a text contains only true statements. Why not consider referring to it in order to decide upon the truth of a hypothesis? It does not matter whether I know for certain that its statements are true. Our concern is what I am justified to infer from the text, presupposing that its statements are true. A striking peculiarity is that in the sciences I am not justified to infer anything from it, even if the text leads me to true conclusions only. Obviously, the evidence I am finally allowed to rely on in the sciences is not a linguistic utterance be it a spoken or a written one. It seems that linguistic utterances do not count as reasonable truthmakers in the sciences as some utterances do in religion. (Quotes from the Bible or the Koran are examples.) It has traditionally been presupposed rather than justified that observation is basic in the sciences. To stress the role of observation seems trivial. How is observation related to scientific statements? (shrink)

»Consciousness and Its Place in Nature« (Chalmers 2003) is the title of an article written by David Chalmers, which deals with the so called hard problems of consciousness, that means, with those problems that do not concern how functions are performed (Chalmers 1997:4), but deal with the emergence of consciousness in the sense of subjective experience. On the one hand, it is important to treat architecture from the very beginning not only as somehow stylish and useful heaps of stones that (...) are additionally embedded in political and philosophical contexts (whatever that means). On the other hand, architecture belongs to nature just as much as trees, apes, and what apes produce. So architecture is situated between what can be grasped from a ›materialistic‹ point of view, on the one hand, and what depends on subjectivity, on the other hand. As far as a general theory of architecture is able to examine what is essential to architecture, one should keep in mind that we would probably not accept a set of characteristics as sufficient for a building being a piece of architecture as we have learned from Wittgenstein and others concerning categories in general (Kleiber 1993). Finding necessary conditions is not as simple as one may expect either. There is a closely related phenomenon however: Are not some individual buildings more representative of architecture as such than others? Gropius once designed a pigsty for the manufacturer Rosenthal. We are inclined to acknowledge it as a part of his architectural work due to the fact that the famous architect Gropius designed it and gave it a typical International Style appearance. Its being purely a pigsty, not a castle or a dwelling, however may be a reason to deny it this status as architecture (Isaacs 1984:1105). (shrink)

The paper explores the extent to which one of the most cited passages in the Western literature on Madhyamaka furnishes a solid basis for particular interpretations regarding the author of the Mūlamadhyamakakārikās. On the one hand it is attempted to show that MMK 24.18 harmonizes well with an exegesis according to which the creator of the concerned work propagated a view that could be labelled by the designation ‘Metaphysical Illusionism’. On the other hand particular features pertaining to natural language and (...) linguistic communication in general are explored in order to a) account for methodological principles as well as limitations to which exegetical undertakings in the pertinent matter are subject and b) to provide an explanation for certain characteristics of Nāgārjuna’s philosophy.

The call for transparency is one of the main slogans of the political present. While Anita Möllering, following the agenda of the “Piraten-Partei”, mostly addresses the demand for transparency to political actors and relates it to democratic procedures, Claus Leggewie discusses the downsides of this fundamentally democratic demand. From this point of view, the central conflict concerns the fixation of the “Piraten-Partei” on a transparent state, while the users of social media hardly reflect on the intransparency of its private (...) commercial operators in a critical way.

Purpose of the article is to provide support for the contention that two fundamental treatises representing the teaching of Madhyamaka, viz. the Mūlamadhyamakakārikās and the Vigrahavyāvartanī, were designed to establish and justify a metaphysical tenet claiming that no particulars of any kind can exist on some level of final analysis and that this was the only primary concern of those works. Whereas the former text is in the first place dedicated to providing proofs of the central metaphysical thesis the major (...) objective of the second treatise lies in a defense of the claim against possible objections. A correlate of this view regarding the content of those two works is on the one hand that the philosophy of the founder of the Madhyamaka-school essentially consists in a metaphysical teaching implying a radical rejection of a stance propagated in earlier Buddhist schools according to which objects of ordinary experience could be reduced to or explained by the existence of other sorts of particulars that can be theoretically postulated. On the other hand the exegesis advocated in the article implies that theorems pertaining to the nature of language or the relationship between language and non-linguistic reality are not at all a predominant issue in the pertinent texts and presumably were not a major matter of concern of early Madhyamaka in general. Accordingly matters pertaining to questions of semantics attain relevance at best in the form of objective consequences which the metaphysical doctrine might entail. The paper focuses on the second chapter of the Mūlamadhyamakakārikās as well as the segment of the Vigrahavyāvartanī which deals with the first major problem, represented by the verses 1–4 and 21–29. The reason is that a detailed and thoroughgoing investigation of these two textual passages is suited to disprove a contention voiced by Western scholars who suppose that the teaching of the founder of Madhyamaka embodies a particular claim pertaining to the relationship between language and non-linguistic reality.

This paper examines the biosemiotic approach to the study of life processes by fashioning a series of questions that any worthwhile semiotic study of life should ask. These questions can be understood simultaneously as: (1) questions that distinguish a semiotic biology from a non-semiotic (i.e., reductionist–physicalist) one; (2) questions that any student in biosemiotics should ask when doing a case study; and (3) still currently unanswered questions of biosemiotics. In addition, some examples of previously undertaken biosemiotic case studies are examined (...) so as to suggest a broad picture of how such a biosemiotic approach to biology might be done. (shrink)

A frayed theoretical discussion has been taking place in most Common Market countries since the mid-1970s, and it has been followed by large-scale empirical research. These studies demonstrate the unforeseen importance of socio-political formations which cannot be comprehended by frameworks based on constitutional law and its understanding of a sound political order. On the contrary, standard constitutional accounts often treat these formations as relics of pre-modern regimes. In fact, however, corporatist arrangements envision socio-political controls not anticipated by the constitutional state. (...) There is an unofficial interaction between associations and interest groups on the one hand, and the government and parties on the other. This has important ramifications for political theory and especially for the conceptualization of democracy. (shrink)

Attentional capture by schematic emotional faces was investigated in two experiments using the flanker task devised by Eriksen and Eriksen (1974). In Experiment 1, participants were presented with a central target (a schematic face that was either positive or negative) flanked by two identical distractors, one on either side (schematic faces that were positive, negative, or neutral). The objective was to identify the central target as quickly as possible. The impact of the flankers depended on their emotional expression. Consistent with (...) a threat advantage hypothesis (negative faces are processed faster and attract more processing resources), responses to positive faces were slower when these were flanked by (response incompatible) negative faces as compared with positive or neutral faces, whereas responses to negative faces were unaffected by the identity of the flankers. Experiment 2 was a standard flanker task with letter stimuli except that the task-neutral flankers were schematic faces that were either positive, negative, or emotionally neutral. In this case, in which faces and emotional expressions were to be ignored, performance seemed entirely unaffected by the faces. This result suggests that attentional capture by emotional faces is contingent on attentional control settings. (shrink)

Karl Polanyi is one of the most influential social scientists of our era. A report of the United Nations Conference on Trade and Development (UNCTAD) begins by noting that we are in a "Polanyi era": a time of dangerously unregulated markets, where the greatest need for decisive political action is matched by the least trust in politics. This handbook provides a comprehensive of recent research on Polanyi's work and ideas, including the central place occupied by his thinking on the relationship (...) between economics and politics. The stellar line-up of contributors to this book explore Polanyi's work reflecting the intrinsic interdisciplinarity of Polanyi's approach to understanding our society, its place in history, its fundamental dynamics, and its contradictions, as well as the methodological issues he raises. The handbook broadly follows a chronological structure beginning with influences on Polanyi, his formative experiences and early works. A significant section is dedicated to Polanyi's seminal work, The Great Transformation, and its impact. Further sections also look at Polanyi's wider influence, on various disciplines and methodological debates, and his ongoing relevance for present-day issues including debates on populism, neoliberalism and low carbon transitions. This handbook is a vital resource for students and scholars of economics, politics, sociology, and other social sciences. (shrink)

This paper investigates the interface between philosophy and biochemistry. While it is problematic to justify the application of a particular philosophical model to biochemistry, it seems to be even more difficult to develop a special “Philosophy for Biochemistry”. Alternatively, philosophy can be used in biochemistry based on an alternative approach that involves an interdependent iteration process at a philosophical and (bio)chemical level (“Exeter Method”). This useful iteration method supplements more abstract approaches at the interface between philosophy and natural sciences, and (...) serves the biochemical community to systematically locate logical inconsistencies that arise from more theoretical aspects of the scientific process. Initial cycles of this iteration process identify the in vitro–in vivo problem as a central epistemological difficulty in biochemical research. While previous attempts have generated ad hoc rules to mend the gap between chemistry, biochemistry and biology in order to justify in vitro experimentation, this paper concludes that in vitro experimentation is heavily based on chemistry and cannot derive definite statements about biological processes. It can, however, generate results that will influence the direction of future biological research. The consequence is that the relationship between in vitro and in vivo experimentation is more of a psychological or social one than of a logical nature. Apart from highlighting these inconsistencies in biochemical thinking (“problem awareness”), the Exeter Method demands an improvement of biochemical terminology that contains separate and unequivocally defined terms for in vitro and in vivo systems.

Consider the following two seemingly unrelated questions. First, why does Rousseau (1993 [1762]) believe that the formation of factions or partial associations is not conducive to the general will in Du Contrat Social, II, 3? Second, why do federal assemblies typically strive for some form of degressive proportionality, i.e. a balance between equal and proportional representation, for the countries in the federation? We will show that there is a surprising connection between these questions. We turn to our first question. It (...) is often thought that Rousseau’s opposition to factions can be interpreted in reference to the Condorcet Jury Theorem. The Condorcet Jury Theorem states that if voters are more likely to be right on some issue than not and cast their votes independently, then the chance that the majority is correct converges to one as the number of voters goes to infinity. This interpretation is tempting, but it is inconsistent with some crucial textual evidence. We turn to our second question. Consider a federation of countries with a decision-making assembly in which each country casts a block vote. On equal representation, the vote of each country has the same weight. On proportional representation, the weights of the votes are proportional to the countries’ population sizes. In between these extremes, we can let the weights increase as a function of population sizes, but smaller countries receive greater weights and larger countries receive lesser weights than proportionality would warrant. Such weightings are called degressively proportional weightings. How can degressive proportionality be justified? And does this justification provide us any guidance as to how these weights should be set? A correct understanding of Rousseau’s misgivings about the formation of factions will hold the key to these questions. (shrink)

Variability is pervasive in spoken language, in particular if one is exposed to two varieties of the same language. Unlike in bilingual settings, standard and dialectal forms are often phonologically related, increasing the variability in word forms. We investigate whether dialectal variability in children’s input affects their ability to recognize words in Standard German, testing non-dialectal vs. dialectal children. Non-dialectal children, who typically grow up in urban areas, mostly hear Standard German forms, and hence encounter little segmental variability in their (...) input. Dialectal children in turn, who typically grow up in rural areas, hear both Standard German and dialectal forms, and are hence exposed to a large amount of variability in their input. We employ the familiar word paradigm for German children aged 12–18 months. Since dialectal children from rural areas are hard to recruit for laboratory studies, we programmed an App that allows all parents to test their children at home. Looking times to familiar vs. non-familiar words were analyzed using a semi-automatic procedure based on neural networks. Our results replicate the familiarity preference for non-dialectal German 12–18-month-old children. Non-dialectal children in the same age range, on the other hand, showed a novelty preference. One explanation for the novelty preference in dialectal children may be more mature linguistic processing, caused by more variability of word forms in the input. This linguistic maturation hypothesis is addressed in Experiment 2, in which we tested older children. These children, who are not exposed to dialectal forms, also showed a novelty preference. Taken together, our findings show that both dialectal and non-dialectal German children recognized the familiar Standard German word forms, but their looking pattern differed as a function of the variability in the input. Frequent exposure to both dialectal and Standard German word forms may hence have affected the nature of lexical representations, leading to more mature processing capacities. (shrink)

In the context of item response theory, linking the scales of two measurement points is a prerequisite to examine a change in competence over time. In educational large-scale assessments, non-identical test forms sharing a number of anchor-items are frequently scaled and linked using two− or three-parametric item response models. However, if item pools are limited and/or sample sizes are small to medium, the sparser Rasch model is a suitable alternative regarding the precision of parameter estimation. As the Rasch model implies (...) stricter assumptions about the response process, a violation of these assumptions may manifest as model misfit in form of item discrimination parameters empirically deviating from their fixed value of one. The present simulation study investigated the performance of four IRT linking methods—fixed parameter calibration, mean/mean linking, weighted mean/mean linking, and concurrent calibration—applied to Rasch-scaled data with a small item pool. Moreover, the number of anchor items required in the absence/presence of moderate model misfit was investigated in small to medium sample sizes. Effects on the link outcome were operationalized as bias, relative bias, and root mean square error of the estimated sample mean and variance of the latent variable. In the light of this limited context, concurrent calibration had substantial convergence issues, while the other methods resulted in an overall satisfying and similar parameter recovery—even in the presence of moderate model misfit. Our findings suggest that in case of model misfit, the share of anchor items should exceed 20% as is currently proposed in the literature. Future studies should further investigate the effects of anchor item composition regarding unbalanced model misfit. (shrink)
