Traditionally, what we are conscious of in self-consciousness is something non-corporeal. But anti-Cartesian philosophers argue that the self is as much corporeal as it is mental. Because we have the sense of proprioception, a kind of body awareness, we are immediately aware of ourselves as bodies in physical space. In this debate the case histories of patients who have lost their sense of proprioception are clearly relevant. These patients do retain an awareness of themselves as corporeal beings, although they hardly (...) feel their bodies. They can initiate movements, and with the help of visual feedback learn to control them. It is shown that the traditional view of the self as immaterial is not supported by these cases. But the argument against this view has to be amended. It relies too much on bodily sensations, and misses the importance of active self-movement. (shrink)

The person with dementia: A plea for a (non-metaphysical) relational notion of personhood In this article we explore the notions of personal identity and personhood, using concrete descriptions of the experiences of people living with dementia as a case study. From an analytical point of view we argue against memory or psychological-continuity criteria of personal identity as too cognitive. Instead we focus on embodiment. The person with dementia, as an embodied human being, is numerically the very same person (s)he was (...) before. Moreover, we argue against a metaphysical notion of personhood. Personhood is constituted by the reactive attitudes of other persons: someone becomes a person and remains a person by being received, and almost literally incorporated, in a community of persons. From a phenomenological point of view we show that embodied intersubjectivity is crucial for the recognition of one person by another. We use Merleau-Ponty’s notion of intercorporality to show that there are ways of keeping people with dementia within this community of persons, of keeping in touch with them, even when many of their cognitive capacities are gone, for instance by singing or dancing together. As long as there is still a shared world, it is up to us to keep recognising someone with dementia as a person, and not as ‘an empty shell’. (shrink)

How fat is the I? Neuroscience and the elusive self This article explores the concept of self in relation to neuroscience. Four options are discussed on the basis of a key representative. The first is the dualist position where the non-material self controls its brain, as defended by Eccles. Next comes the option of the self as a relatively or completely powerless entity within the brain, as exemplified by Libet’s experiments on free will. The third option is the identity of (...) self and brain, as argued by Dennett. The last option is the identity of self and body, and here Gallagher is the representative. It is shown that no monist position is completely consistently defended. In the conclusion, four factors are identified that hinder a simple and consistent monist conceptualisation of the self in the context of neuroscience. (shrink)

This paper takes an evolutionary approach to what we are, namely autopoietic systems with a first person perspective on our surroundings and ourselves. This in contrast with Thomas Metzinger.

What are we, most fundamentally? Two topical answers to this question are discussed and rejected and a more evolutionary account is offered. Lynne Baker argues that we are persons: beings with a first-person perspective. Persons form a separate ontological category, with persistence conditions that are different from those of the body. Eric Ol-son, by contrast, claims that we are human organisms. No psychological property is definitive of what we are. Our persistence conditions are those of the human organism. In a (...) more evolutionary approach to the notion of personhood, it is argued that we are indeed, most fundamentally, beings with a first-person perspective. But such a perspective is not definitive of personhood. It is precisely living organisms that have it, and cannot fail to have it. There is no separate ontological category of persons. (shrink)

This paper deals with the perception of depth in two-dimensional pictures. Two indirect theories of perception, the Mainstream Theory and the Projection Theory, are compared with a direct Adverbial Theory. Apart from seeming to be the philosophical counterpart to present-day empirical theories of perception, the first two theories seem to be tailor-made to deal with this phenomenon, where the perceived space is certainly not out there, on or behind the canvas: they claim that pictorial space is constructed by the brain (...) as the direct object of perception. In contrast, the Adverbial Theory seems unsuited to deal with this phenomenon. I argue, however, that both constructivist theories are incoherent. They misconstrue the intentionality of perception, and fail to attend to the perceptual experience itself. The version of the Adverbial Theory that I defend claims that nothing needs to be constructed: the picture is the direct object of perception, but we perceive it in a certain way. The brain creates no pictorial space; there is only a perceptual experience as of a three-dimensional scene. The Adverbial Theory can thus account for the empirical data, without suffering from coherence problems. (shrink)

In this article an analysis of perception is given that accommodates both the fact that perception is a kind of interaction with the world, and the existence of illusions and hallucinations. This analysis, the Adverbial Approach, is contrasted with Representationalism and Enactivism. I will confront all three theories of perception with three test cases: a ginger cat, a ginger cat hidden behind a picket fence, and a ginger cat as in the Bonnet syndrome. I will argue that Representationalism can account (...) for illusions and hallucinations by postulating the existence of internal representations as the direct object of perception, but by doing so fails to account for the interaction with the world. Moreover, I will show that by combining the Cartesian notion of mental representations with physicalism, it is incoherent. Enactivism, on the other hand, discards the need for internal representations and analyses perception as direct interaction with the world, but completely fails to account for hallucinations. The Adverbial Approach can do justice to both aspects of perception: it stresses the fact that perception is indeed interaction with the world and not with any internal representation of it, but leaves room for perceptual experience as distinct from that interaction. Finally I will diagnose the problems of both Representationalism and Enactivism as a faulty conception of the intentionality of perception. (shrink)

It is widely accepted that embodiment is crucial for any self-aware agent. What is less obvious is whether the body has to be real, or whether a virtual body will do. In that case the notion of embodiment would be so attenuated as to be almost indistinguishable from disembodiment. In this article I concentrate on the notion of embodiment in human agents. Could we be disembodied, having no real body, as brains-in-a-vat with only a virtual body? Thought experiments alone will (...) not suffice to answer this Cartesian question. I will draw on both philosophical arguments and empirical data on phantom phenomena. My argument will proceed in three steps. Firstly I will show that phantom phenomena provide a prima facie argument that real embodiment is not necessary for a human being. Secondly I will give a philosophical argument that real movement must precede the intention to move and to act. Agents must at least have had real bodies once. Empirical data seems to bear this out. Finally, however, I will show that a small number of aplasic phantom phenomena undermines this last argument. Most people must have had a real body. But for some people a partly virtual, unreal, phantom body seems to suffice. Yet though there is thus no knockdown argument that we could not be brains-in-a-vat, we still have good reasons to suppose that embodiment must be real, and not virtual. (shrink)

The article consists of three main sections, in which I successively discuss the nature and role of realization, interpretation and abstraction in experimental and observational processes. In this way, these sections address several fundamental problems in philosophy of science, ontology and epistemology, and philosophy of language. Section 1 introduces the notion of realization processes, and argues that successful realization requires causal judgments. The second section discusses the role of conceptual interpretation in experiments and observations, explains how realization and interpretation can (...) be distinguished, and emphasizes the significance of different types and ranges of experimental and observational reproducibility. It also includes a subsection on the issue of reproducibility in contemporary social sciences and psychology. Section 3 explains how concepts are abstracted from existing realization processes, and concludes that abstraction bestows a nonlocal meaning on these extensible concepts. In addition, I discuss and criticize some rival views of abstraction and concept meaning (to wit, mentalism and localism). The article concludes with some observations on the notion of a (cognitive) trinity. In my reply, I respond to the points raised in the six commentary papers. The following issues are addressed: the place of causality in physics (Steffen Ducheyne), perception in ordinary life (Monica Meijsing), the role of reproducibility in psychology and the social sciences (Daniël Lakens, Ruud Abma), the significance and implications of conceptual innovation (Lieven Decock), and the relationship between meaning, communication and ontology (Martin Stokhof and Michiel van Lambalgen).

Background:Nurses and nursing students appear vulnerable to moral distress when faced with ethical dilemmas or decision-making in clinical practice. As a result, they may experience professional dissatisfaction and their relationships with patients, families, and colleagues may be compromised. The impact of moral distress may manifest as anger, feelings of guilt and frustration, a desire to give up the profession, loss of self-esteem, depression, and anxiety.Objectives:The purpose of this review was to describe how dilemmas and environmental, relational, and organizational factors contribute (...) to moral distress in undergraduate student nurses during their clinical experience and professional education.Research design:The research design was a systematic literature review.Method:The search produced a total of 157 articles published between 2004 and 2014. These were screened with the assessment sheet designed by Hawker and colleagues. Four articles matched the search criteria (one quantitative study and three qualitative), and these were separately read and analyzed by the researchers. The process of review and analysis of the data was supervised by a colleague experienced in moral distress who provided an independent quality check.Ethical consideration:Since this was a systematic review, no ethical approval was required.Findings:From the analysis, it emerged that inequalities and healthcare disparities, the relationship with the mentor, and students’ individual characteristics can all impact negatively on the decisions taken and the nursing care provided, generating moral distress. All these factors condition both the clinical experience and learning process, in addition to the professional development and the possible care choices of future nurses.Conclusion:Few studies dealt with moral distress in the setting of nurse education, and there is a knowledge gap related to this phenomenon. The results of this review underline the need for further research regarding interventions that can minimize moral distress in undergraduate nursing students. (shrink)

The computational genomics community has come increasingly to rely on the methodology of creating annotations of scientific literature using terms from controlled structured vocabularies such as the Gene Ontology (GO). We here address the question of what such annotations signify and of how they are created by working biologists. Our goal is to promote a better understanding of how the results of experiments are captured in annotations in the hope that this will lead to better representations of biological reality through (...) both the annotation process and ontology development, and in more informed use of the GO resources by experimental scientists.

The DAPRECO knowledge base is the main outcome of the interdisciplinary project bearing the same name. It is a repository of rules written in LegalRuleML, an XML formalism designed to be a standard for representing the semantic and logical content of legal documents. The rules represent the provisions of the General Data Protection Regulation, the new Regulation that is significantly affecting the digital market in the European Union and beyond. The DAPRECO knowledge base builds upon the Privacy Ontology, which provides (...) a model for the legal concepts involved in the GDPR, by adding a further layer of constraints in the form of if-then rules, referring either to standard first order logic implications or to deontic statements. If-then rules are formalized in reified Input/Output logic and then codified in LegalRuleML. Reified Input/Output logic is an application of standard Input/Output logic for legal reasoning, in which Input/Output logic is combined with the reification-based approach in Hobbs and Gordon. The DAPRECO knowledge base is then a case study for reified Input/Output logic, and it shows that the formalism indeed appears to be a good candidate to effectively formalize, via uniform and simple representations, complex linguistic/deontic phenomena that may be found in legal texts. To date, the DAPRECO knowledge base is the biggest knowledge base in LegalRuleML and Input/Output logic freely available online. (shrink)

The new result of this paper is that for θ-stable we have S1[θ] = D[θ, L, ∞]. S1 is Hrushovski's rank. This is an improvement of a result of Kim and Pillay, who for simple theories under the assumption that either of the ranks be finite obtained the same identity. Only the first equality is new, the second equality is a result of Shelah from the seventies. We derive it by studying localizations of several rank functions, we get the followingMain (...) Theorem. Suppose that μ is regular satisfying μ ≥ |T|+, p is a finite type, and Δ is a set of formulas closed under Boolean operations. If either R[p, Δ, μ+] < ∞ or p is Δ-stable and μ satisfies “for every sequence {μi : i < |Δ| + ℵ0} of cardinals μi < μ we have that equation image holds”, then S[p, Δ, μ+] = D[p, Δ, μ+] = R[p, Δ, μ+].The S rank above is a localized version of Hrushovski's S1 rank. This rank, as well as our systematic use of local stability, allows us to get a more conceptual proof of the equality of D and R, which is an old result of Shelah. A particular case of the theorem offers a new sufficient condition for the equality of S1 and D[·, L, ∞]. We also manage, due to a more general approach, to avoid some combinatorial difficulties present in Shelah's original exposition. (shrink)

Randomized controlled trial trial designs exist on an explanatory-pragmatic spectrum, depending on the degree to which a study aims to address a question of efficacy or effectiveness. As conceptualized by Schwartz and Lellouch in 1967, an explanatory approach to trial design emphasizes hypothesis testing about the mechanisms of action of treatments under ideal conditions, whereas a pragmatic approach emphasizes testing effectiveness of two or more available treatments in real-world conditions. Interest in, and the number of, pragmatic trials has grown substantially (...) in recent years, with increased recognition by funders and stakeholders worldwide of the need for credible evidence to inform clinical decision-making. This increase has been accompanied by the onset of learning healthcare systems, as well as an increasing focus on patient-oriented research. However, pragmatic trials have ethical challenges that have not yet been identified or adequately characterized. The present study aims to explore the views of key stakeholders with respect to ethical issues raised by the design and conduct of pragmatic trials. It is embedded within a large, four-year project that seeks to develop guidance for the ethical design and conduct of pragmatic trials. As a first step, this study will address important gaps in the current empirical literature with respect to identifying a comprehensive range of ethical issues arising from the design and conduct of pragmatic trials. By opening up a broad range of topics for consideration within our parallel ethical analysis, we will extend the current debate, which has largely emphasized issues of consent, to the range of ethical considerations that may flow from specific design choices. Semi-structured interviews with key stakeholders, across multiple jurisdictions, identified based on their known experience and/or expertise with pragmatic trials. We expect that the study outputs will be of interest to a wide range of knowledge users including trialists, ethicists, research ethics committees, journal editors, regulators, healthcare policymakers, research funders and patient groups. All publications will adhere to the Tri-Agency Open Access Policy on Publications. (shrink)

Newborn bloodspot screening programs are some of the longest running population screening programs internationally. Debate continues regarding the need for parents to give consent to having their child screened. Little attention has been paid to how meanings of consent-related terminology vary among stakeholders and the implications of this for practice. We undertook semi-structured interviews with parents, healthcare professionals and policy decision makers in two Canadian provinces. Conceptions of consent-related terms revolved around seven factors within two broad domains, decision-making and information (...) attainment. Decision-making comprised: parent decision authority; voluntariness; parent engagement with decision-making; and the process of enacting choice. Information ascertainment comprised: professional responsibilities ; parent responsibilities; and the need for discussion and understanding prior to a decision. Our findings indicate that consent-related terms are variously understood, with substantive implications for practice. We suggest that consent procedures should be explained descriptively, regardless of approach, so there are clear indications of what is expected of parents and healthcare professionals. Support systems are required both to meet the educational needs of parents and families and to support healthcare professionals in delivering information in a manner in keeping with parent needs.

The aim of this article is to analyse the opinions of journalists and citizens regarding the interdependence of public media and the official sources of political power in Spain. Little research of this kind has been done in the Spanish context. Journalists and citizens representing four Spanish regions?Catalonia, Madrid, the Basque Country, and Andalusia?were questioned about their opinions regarding this interdependency. The methodology used in this research is based on quantitative techniques (surveys) and qualitative techniques (in-depth interviews and focus groups). (...) The results prove that the opinions of journalists differ from those of citizens for the majority of questions asked. Citizens are more inclined to follow directions from official sources than are journalists. The geographical background of the respondents proved to be a significant factor in terms of variation in answers. Journalists from Catalonia and the Basque country are much more reluctant to follow government directives on issues of counter terrorism or in cases of national emergency. (shrink)

Binge-purge eating disorders, such as bulimia nervosa and binge eating disorder, may share some neurobiological features. Electroencephalography is a non-invasive measurement modality that may aid in research and diagnosis of BP-ED. We conducted a systematic review of the literature on EEG findings in BP-ED, seeking to summarize and analyze the current evidence, as well as identify shortcomings and gaps to inform new perspectives for future studies. Following PRISMA Statement recommendations, the PubMed, Embase, and Web of Science databases were searched using (...) terms related to “electroencephalography” and “binge-purge” eating disorders. Of 555 articles retrieved, 15 met predefined inclusion criteria and were included for full-text analysis. Eleven studies investigated EEG by means of event-related potentials in BP-ED individuals: 7 using eating disorder-related stimuli and 4 using non-eating disorder-related stimuli. These studies found significant differences in the N200, P200, P300, and LPP components in BP-ED participants compared to controls, indicating that this population exhibits impairments in selective attention, attentional allocation/processing, and allocation of motivational or emotion-based attention. Five studies investigated EEG using frequency analysis; reporting significant differences in beta activity in fronto-temporal and occipito-temporo-parietal areas in BP-ED individuals compared to controls, revealing a dysfunctional brain network. However, the small number of studies, the heterogeneity of samples, study paradigms, stimulus types, and the lack of an adequate assessment of neuropsychological parameters are some limitations of the current literature. Although some EEG data are promising and consistent with neuroimaging and neuropsychological findings in individuals with BP-ED, future studies need to overcome current methodological shortcomings.

This paper examines folk theories of algorithmic recommendations on Spotify in order to make visible the cultural specificities of data assemblages in the global South. The study was conducted in Costa Rica and draws on triangulated data from 30 interviews, 4 focus groups with 22 users, and the study of “rich pictures” made by individuals to graphically represent their understanding of algorithmic recommendations. We found two main folk theories: one that personifies Spotify and another one that envisions it as a (...) system full of resources. Whereas the first theory emphasizes local conceptions of social relations to make sense of algorithms, the second one stresses the role of algorithms in providing a global experience of music and technology. We analyze why people espouse either one of these theories and how these theories provide users with resources to enact different modalities of power and resistance in relation to recommendation algorithms. We argue that folk theories thus offer a productive way to broaden understanding of what agency means in relation to algorithms. (shrink)

Amid now extensive debates about cosmopolitanism in political theory, this article explores the implications of Axel Honneth’s recognition theory for issues in international justice, not least the dire situation of poverty in the world. In contrast with a purely resource-distributive approach, the essay turns particularly to Honneth’s recent revival of the Lukácsian concept of reification as a process of self-distancing from the elementary humanity of others. Specifically, Honneth re-formulates reification as a failure of an elementary or ‘antecedent’ form of recognition. (...) From the perspective of his theory, reification connotes the forgetfulness of others’ fundamental humanity. While Honneth takes such forgetfulness to become most readily apparent in dramatic violations such as the Holocaust, the article interprets his theory to explain, and eventually to challenge, the passive acceptance by many of dire material injustices. The article develops the implications of this challenge by interpreting from Honneth’s framework a duty to question international policies which tend to reify and objectify the least well off in the world, whilst remaining cognizant of the limits of de-reification to the more extensive, meaningful alleviation of poverty globally.

While the right to freedom of expression is of great importance in liberal societies, liberal governments should be wary of speech that disparages minority groups. This issue is particularly problematic when minority women publicly criticise gender oppression within their communities. By focusing on the controversy over the play Behzti in 2004, this article explores the difficulties involved in protecting individual women’s rights to criticise injustice, when doing so risks perpetuating negative stereotypes in society at large. If liberal polities wish to (...) preserve an ethos in society that enables minority women to speak out about their experience of oppression, then there is sometimes a case for restricting the right to free speech in these cases. By comparing Behzti with two other works, the article proposes a three-part test to indicate when liberals should seriously consider informal restrictions on free speech when this problem arises.

Significant scientific and technological advances in intensive care have been made. However, patients in the intensive care unit may experience discomfort, loss of control, and surreal experiences. This has generated relevant debates about how to humanize the intensive care units and whether humanization is necessary at all. This paper aimed to explore how humanizing intensive care is described in the literature. A scoping review was performed. Studies published between 01.01.1999 and 02.03.2020 were identified in the CINAHL, Embase, PubMed, and Scopus (...) databases. After removing 185 duplicates, 363 papers were screened by title and abstract. Full-text screening of 116 papers led to the inclusion of 68 papers in the review based on the inclusion criteria; these papers mentioned humanizing or dehumanizing intensive care in the title or abstract. Humanizing care was defined as holistic care, as a general attitude of professionals toward patients and relatives and an organizational ideal encompassing all subjects of the healthcare system. Technology was considered an integral component of intensive care that must be balanced with caring for the patient as a whole and autonomous person. This holistic view of patients and relatives could ameliorate the negative effects of technology. There were geographical differences and the large number of studies from Spain and Brazil reflect the growing interest in humanizing intensive care in these particular countries. In conclusion, a more holistic approach with a greater emphasis on the individual patient, relatives, and social context is the foundation for humanizing intensive care, as reflected in the attitudes of nurses and other healthcare professionals. Demands for mastering technology may dominate nurses’ attention toward patients and relatives; therefore, humanized intensive care requires a holistic attitude from health professionals and organizations toward patients and relatives. Healthcare organizations, society, and regulatory frameworks demanding humanized intensive care may enforce humanized intensive care. (shrink)

Employee social network strategies play a key role in firm strategies and organizational performance. Currently, scholars underestimate the contributions of employee social strategies in firm strategies. Little is known how informal employee social networks, group entitativity and competition could shape and direct firm strategies and organizational performance. The article examines social network theory and strategic management’s content, process and open schools of thought to propose a new interpretation for managing firm strategies. More specifically, the author examines alternate causal paths, underlying (...) processes and structures as mechanisms in employee social network strategies within a theoretical framework. The article proposes 4 theoretically driven propositions and makes two contributions. First, the article contributes to organizational behavior literature by focusing on the literature gap in network dynamics and competitive actions through employee social networks. Second, although there is immense literature on positive and negative employee competition in business, the article makes a contribution to the strategic management literature by moving beyond formalized structures and roles within an organization to focus on the multilevel informal workplace social interactions and processes that impact strategizing activities. Overall, the article extends strategy research in relation to how employee social networks operate through competition and group entitativity in firm strategies. (shrink)

A serious problem confronting discourses on recognition is that of showing equal respect for citizens’ diverse cultural identities whilst at the same time attending to feminist concerns. This article focuses on the complex issues emerging from the recent legislation prohibiting the Muslim veil in French state schools. I respond to these problems by defending two conditions of a postcolonial and feminist approach to the politics of recognition. This approach should be, first, transformative, in the sense of widening its conception of (...) core values through an engagement with cultural difference. Second, it should be critical in its orientation to practices affecting women adversely within any social group. An integration of these concerns is proposed in terms of ‘affective citizenship’. This approach supports the different components of women’s autonomous functioning, through a universalistic commitment to the creative expression of their hybrid identities. (shrink)

The results in this paper are in a context of abstract elementary classes identified by Shelah and Villaveces in which the amalgamation property is not assumed. The long-term goal is to solve Shelah’s Categoricity Conjecture in this context. Here we tackle a problem of Shelah and Villaveces by proving that in their context, the uniqueness of limit models follows from categoricity under the assumption that the subclass of amalgamation bases is closed under unions of bounded, -increasing chains.

O estudo filosófico da ética sobre as interações entre os seres humanos e as tecnologias que empregam a Inteligência Artificial se tornou um tópico popular e importante como nunca antes. O estudo dos problemas que concernem essas interações justifica-se por conta das transformações tecnológicas pelas quais as sociedades humanas têm passado, e que ainda podem acarretar profundas mudanças legais, políticas e sociais. O artigo tem como objetivo principal identificar o papel da ética, enquanto disciplina filosófica, com relação ao recente e (...) promissor domínio de investigação sobre a ética da Inteligência Artificial. Após apresentar a posição do filósofo Peter Railton na ética aplicada à Inteligência Artificial, o artigo reconstitui as suas explicações na ética normativa e na metaética. Ao ilustrar as conexões entre a ética aplicada à Inteligência Artificial e a teoria moral, o artigo argumenta que o papel da ética na ética da Inteligência Artificial pode ser explicitado com o auxílio da engenharia conceitual. Essa abordagem mostra que conceitos como ‘agente’ e ‘interesse’, que são cruciais para a ética, como pode ser visto nas explicações de Railton, não devem ser pensados exclusivamente pela ética, ou mesmo somente pela filosofia, mas necessitam ser informados pelas ciências naturais e humanas. O artigo enfatiza a necessidade de realizar a tarefa filosófica de pensar a ética para além da ética, em um contexto interdisciplinar capaz de lidar com os complexos problemas práticos que impactam as sociedades humanas.

Esta reflexão pretende mostrar o discurso racional cartesiano na segunda prova da existência de Deus. Para tanto, Descartes se depara com uma pergunta central: qual a causa da existência da res cogitans que é finita e possui a ideia de infinito? A resposta é encontrada na desproporcionalidade ontológica entre o finito e o infinito. Essa desproporcionalidade é elucidada mediante dois conceitos: o princípio de causalidade que determina que a causa deve ser igual ou superior a coisa causada e o princípio (...) de criação contínua em que a causa que criou o ser não é menor do que aquela que o conserva em sua existência. As objeções destacadas no texto contra os argumentos cartesianos foram escolhas deliberadas que servem para elucidar a importância da racionalidade como fundamento para a prova da existência de Deus. A relação entre o entendimento e a liberdade, apresentada no texto sucintamente, justifica a impossibilidade da res cogitans ser causa de si mesma. Palavras-chave: Infinito; finito; causalidade; criação contínuaThis essay aims to show the rational Cartesian discourse on the second proof of God’s existence. In order to do so, Descartes faces a core question: which is the cause for the existence of the res cogitans that is finite in front of the idea of the infinite? The answer is found in the ontological disproportionality between the finite and the infinite. This disproportionality is elucidated through a couple crucial concepts: the principle of causality, which determines that the cause must be equal or superior to the caused thing and the principle of continuous creation, in which the cause that created the being is not inferior than the one that preserves its existence. The objections highlighted in the text against the Cartesian arguments were deliberated choices, to elucidate the relevance of rationality as the foundation for the proof of God’s existence. The relation between the understanding and the liberty, showed on the text even if succinctly, justifies the impossibility of the res cogitans to be the cause of itself. Key words: Infinite; finite; causality; creation continuous. (shrink)

Through cultural transmission, repeated learning by new individuals transforms cultural information, which tends to become increasingly compressible . Existing diffusion chain studies include in their design two processes that could be responsible for this tendency: learning and reproducing . This paper manipulates the presence of learning in a simple iterated drawing design experiment. We find that learning seems to be the causal factor behind the increase in compressibility observed in the transmitted information, while reproducing is a source of random heritable (...) innovations. Only a theory invoking these two aspects of cultural learning will be able to explain human culture's fundamental balance between stability and innovation. (shrink)

In this chapter, we offer a reconstruction of the evolution of Leibniz’s thought concerning the problem of the infinite divisibility of bodies, the tension between actuality, unassignability, and syncategorematicity, and the closely related question of the possibility of infinitesimal quantities, both in physics and in mathematics.Some scholars have argued that syncategorematicity is a mature acquisition, to which Leibniz resorts to solve the question of his infinitesimals – namely the idea that infinitesimals are just signs for Archimedean exhaustions, and their unassignability (...) is a nominalist maneuver. On the contrary, we show that syncategorematicity, as a traditional idea of classical scholasticism, is a feature of young Leibniz’s thinking, from which he moves away in order to solve the same problem, as he gains mathematical knowledge.We have divided Leibniz’s path toward his mature view of infinitesimals into five phases, which are especially significant for reconstructing the entire evolution. In our reconstruction, an important role is played by Leibniz’s text De Quadratura Arithmetica. Based on this and other texts, we dispute the thesis that fictionality coincides with syncategorematicity, and that unassignability can be bypassed. (In this chapter, we employ “syncategorematic” as a shorthand for “eventually identifiable with a procedure of exhaustion” and, as a consequence, “involving only assignable quantities.” We also identify syncategorematicity with potentiality, as suggested by some part of the scholastics, and in Sect. 2.2, we show that the two characterizations are equivalent, provided that “potentiality” is intended in the correct way: namely as in the unending iterative procedures of Greek mathematics.) On the contrary, we maintain that unassignability, as incompatible with the principle of harmony, is the ultimate reason for the fictionality of infinitesimals. (shrink)

We investigate the emergence of iconicity, specifically a bouba-kiki effect in miniature artificial languages under different functional constraints: when the languages are reproduced and when they are used communicatively. We ran transmission chains of participant dyads who played an interactive communicative game and individual participants who played a matched learning game. An analysis of the languages over six generations in an iterated learning experiment revealed that in the Communication condition, but not in the Reproduction condition, words for spiky shapes tend (...) to be rated by naive judges as more spiky than the words for round shapes. This suggests that iconicity may not only be the outcome of innovations introduced by individuals, but, crucially, the result of interlocutor negotiation of new communicative conventions. We interpret our results as an illustration of cultural evolution by random mutation and selection. (shrink)
