This paper examines David Hull’s and Peter Godfrey-Smith’s accounts of biological individuality using the case of biofilms. Biofilms fail standard criteria for individuality, such as having reproductive bottlenecks and forming parent-offspring lineages. Nevertheless, biofilms are good candidates for individuals. The nature of biofilms shows that Godfrey-Smith’s account of individuality, with its reliance on reproduction, is too restrictive. Hull’s interactor notion of individuality better captures biofilms, and we argue that it offers a better account of biological individuality. However, Hull’s notion of (...) interactor needs more precision. We suggest some ways to make Hull’s notion of interactor and his account of individuality more precise. Generally, we maintain that biofilms are a good test case for theories of individuality, and a careful examination of biofilms furthers our understanding of biological individuality. (shrink)

de Queiroz (1995), Griffiths (1999) and LaPorte (2004) offer a new version of essentialism called "historical essentialism". According to this version of essentialism, relations of common ancestry are essential features of biological taxa. The main type of argument for this essentialism proposed by Griffiths (1999) and LaPorte (2004) is that the dominant school of classification, cladism, defines biological taxa in terms of common ancestry. The goal of this paper is to show that this argument for historical essentialism is unsatisfactory: cladism (...) does not assume that relations of common ancestry are essential attributes of biological taxa. Therefore, historical essentialism is not justified by cladism. (shrink)

Cooperative behaviors within a group face the risk of being exploited by `free-riders,' individuals that reap the benefits produced by cooperators without paying the costs of cooperating. Free-riders are often perceived as a burden to the group, since the group's survival depends on tasks performed by cooperators. However, this paper challenges this perspective, arguing that an excess of cooperators may actually lower the efficiency and persistence of groups. The perspective presented in this paper has ramifications to broader issues in philosophy, (...) particularly the challenge of how to balance self-interest with the collective interests of the group. Ultimately, this paper seeks to highlight some of the subtle ways free-riders positively impact their groups, an aspect of free-riding that is often overlooked in discussions about cooperation.

Nature is replete with borderline cases that fall somewhere between organisms and communities, such as lichens, biofilms, and the Portuguese Man-of-War. At first glance, the existence of such borderline cases might suggest that the concept of what constitutes an organism is too fuzzy to be useful in evolutionary biology. Yet, the notion of organisms is entrenched within central debates in evolution, including discussions over how fitness should be measured, what the bearers of adaptations and fitness are, and the status of (...) holobionts. Finally, accounts of organisms can set the stage for explanations of how multicellularity evolved. In particular, characterizing multicellular organisms in terms of the level of cooperation between their cells suggests that their evolution required the presence of mechanisms that could suppress conflict between cells.

Kripke argues for origin essentialism, the view that the same individual cannot have multiple origins. Sober hypothesises that Kripke's origin essentialism applies to biological species. This paper shows that Sober's hypothesis fails. Because Kripke's original argument is invalid, it cannot vindicate Sober's proposal. Salmon offers an influential reformulation of Kripke's argument but his argument fails to extend to species: the notion of an individual's origin is too narrow to apply to species, and Salmon's argument rests on a thought experiment that (...) conflicts with how species evolve. Thus, Sober and others are wrong to think that Kripke's origin essentialism can save species essentialism. (shrink)

One curious phenomenon of several social groups is that they are ‘redundant’ in the sense that they contain more cooperators than strictly needed to complete certain group tasks, such as foraging. Redundancy is puzzling because redundant groups are particularly susceptible to invasion by defectors. Yet, redundancy can be found in groups formed by a wide range of organisms, including insects and microbes. Birch ([2012]) has recently argued that coercive behaviours might account for redundancy using insect colonies as a case study. (...) However, microbial examples suggest redundancy can evolve without coercive behaviours. This paper formulates an explanation for redundancy that does not require targeted punishment of defectors; instead, it proposes that redundancy might be due to ignorance. Specifically, it is suggested that redundancy evolves as a by-product of selection when group members have to opt whether to cooperate or not while being blind to the strategies of others. Accordingly, possessing information about the strategies of the group members might undermine rather than facilitate cooperation within groups. (shrink)

Some mathematicians and philosophers contend that set theory plays a foundational role in mathematics. However, the development of category theory during the second half of the twentieth century has encouraged the view that this theory can provide a structuralist alternative to set-theoretical foundations. Against this tendency, criticisms have been made that category theory depends on set-theoretical notions and, because of this, category theory fails to show that set-theoretical foundations are dispensable. The goal of this paper is to show that these (...) criticisms are misguided by arguing that category theory is entirely autonomous from set theory. (shrink)

Microbes often live in association with dense multicellular aggregates, especially biofilms, and the construction of these aggregates typically requires microbial cells to produce public goods, such as enzymes and signaling molecules. Public-goods producers are, in turn, vulnerable to exploitation by free-rider cells that consume the public goods without paying for their production costs. The cell population of a biofilm or other microbial aggregates are expected to pass through bottlenecks due to a wide range of factors, such as antibiotic treatments and (...) dispersal. The goal of this article is to make the case for the relevance of population bottlenecks at shaping the social interactions within microbial aggregates. The effect of bottlenecks on microbial aggregates is complex in that bottlenecks can favor producers under certain circumstances, but not in others. The concept of the Volunteer’s Dilemma from game theory will be used to motivate the hypothesis that this partly occurs because of how bottlenecks alter the risk of being a producer in a microbial aggregate. Finally, the role of bottlenecks in the microbial world impacts key issues in evolutionary biology, including the importance of ecology at shaping social evolution, and the evolution of multicellularity from unicellular ancestors.

Doolittle :351–378, 2013) and Ereshefsky and Pedroso argue that selection can act at the level of biofilms and other microbial communities. Clarke is skeptical and argues that selection acts on microbial cells rather than microbial communities. Her main criticism is that biofilms lack one of the ingredients required for selection to operate: heritability. This paper replies to her concern by elaborating how biofilm-level traits can be inheritable.

Multiple biological groups, such as ant colonies, appear to have a noteworthy inefficiency: they contain vast amounts of redundant members that are not strictly needed to maintain the group. Philosophers and biologists have proposed that such inefficiency is illusory because redundancy enhances the resilience of groups when living under harsh conditions. Still, this proposal is unsatisfactory in different respects. First, it is too vague to account for when redundancy is selectively advantageous. Furthermore, it overlooks cases in which redundancy fails to (...) increase the resilience of groups. This paper offers an account of group redundancy that addresses these difficulties. Specifically, it advances the hypothesis that the mere presence of harsh conditions is not what drives the evolution of redundancy; rather, it is the fact organisms are often unable to predict when they will face harsh conditions. Redundancy enables groups to properly respond to unpredictable circumstances without resorting to the unreliable detection systems of their members. A better understanding of the phenomenon of redundancy is likely to impact other key issues in philosophy of science, including the evolution of cooperation and transitions in individuality, and the role of redundancy in complex systems, be they biological or not.

From the standpoint of the school settings, sport participation constitutes a key strategy concerning the manifestation of positive behaviors that result from the development of personal and social responsibility. Based on the TPSR model, the goal of this study was to evaluate the effects of an intervention geared toward teaching life skills through sport to youngsters who had been committed. The participants were evaluated before and after the intervention. After the initial evaluation, they were randomly assigned to the experimental and (...) control groups. The experimental group took part in the community football program, while the control group attended physical education classes not based on the TPSR model. The experimental model consisted of 3 weekly sessions over the course of 6 weeks, which totaled 18 sessions. This investigation supplied empirical evidence concerning the potential of community sport programs in the teaching and development of life skills deemed necessary for an adequate reintegration of such at-risk youngsters. The model was shown to be valid both in stimulating changes of attitudes and in promoting the adherence to socially positive behaviors. The effectiveness of the model, as well as its unique approach, make its application attractive to both the youngsters and the professionals. This program facilitates the training of youngsters to act, in the sense of promoting both their autonomy and the acquisition of a system of ethics and moral values within a culture of responsibility for how decisions affect the individual and the community. Finally, this intervention generated empirical support in favor of the argument that sport constitutes a unique opportunity within the educational process to establish values, beliefs, attitudes, and practical habits pertaining relationships and cooperation that generate social responsibility in individuals.

Theology as a science reflects the phenomena that in some way constitute the experience of faith in society, that is, looking at the world and the various periods of history with the help of the various sciences: anthropology, the sciences of religion and sociology. With the black traffic of the African continent, came the various customs lived in Africa: culture, religiosity, African myths, beliefs in the Orixás, all these elements constituted the Brazilian cultural imaginary. Thus syncretism arises as a form (...) of resistance and survival of faith. The Church with the Second Vatican Council and the post-conciliar declarations opens a new way of being in the world, valuing dialogue with other religions and cultures. (shrink)

Throughout the last decades, scientific and therapeutic communities have made common efforts to collect reliable information concerning the efficacy of psychotherapies. One of these initiatives has, recently, involved the psychodrama community and its desire to achieve progress in the validation of this therapy. Based on Robert Elliot's Hermeneutic Single Case Efficacy Design (HSCED), we followed five participants (3 women, 2 men, aged 27-48) of a psychodrama group over the course of their therapeutic process, which ranged from 24 months to 5 (...) years. We chose one of them for the single case study. Quantitative outcome measures included the Portuguese versions of the Revised Spontaneity Assessment Inventory, Clinical Outcome Routine Evaluation and the individualized Personal Questionnaire. Qualitative process measures included Helpful Aspects of Therapy Form and the Client Change Interview. Participants generally reported improvement in their personal therapeutic goals, decrease in symptoms and life problems, and some showed a marked increase in spontaneity levels. In the single case presented, these results are confirmed, and following decision criteria it is possible to assert that the participant improved in all the variables assessed and that therapy is the main cause of these changes. Furthermore, the participant frequently rated psychodrama sessions as being helpful and stated they had a transformational impact on his life. This research contributes towards validating psychodrama as an efficient therapeutic method, hopefully stimulating practitioners to integrate therapy and research - which, for years, were considered independent and incompatible - and to facilitate their use in a complementary way.

Recent developments in Continental philosophy have included the emergence of a school of “speculative realism,” which rejects the human-centered orientation that has long dominated Continental thought. Proponents of speculative realism differ on several issues, but many agree on the need for an object-oriented ontology. Some speculative realists identify realism with materialism, while others accord equal reality to objects that are non-material, even fictional. Several thinkers retain a focus on difference, a well-established theme in Continental thought. This paper looks at speculative (...) realism from the perspective of systems theory. Many of the tenets of speculative realism have long been features of systems metaphysics and are expressed clearly in a systems framework. However, some views of some speculative realists differ substantially from systems theoretic ideas. (shrink)

The phenomenon of altruism extends from the biological realm to the human sociocultural realm. This article sketches a coherent outline of multiple types of altruism of progressively increasing scope that span these two realms and are grounded in an ever-expanding sense of “self.” Discussion of this framework notes difficulties associated with altruism at different levels. It links scientific ideas about the evolution of cooperation and about hierarchical order to perennial philosophical and religious concerns. It offers a conceptual background for inquiry (...) into societal challenges that call for altruistic behavior, especially the challenge of environmental and social sustainability. (shrink)

In this lively collection ten philosophers tackle the notoriously elusive issues raised by religious discourse in a series of linked debates. The debates focus on reason and faith; the logic of mysticism; the meaning of the word 'God'; language, biblical interpretation and worship; and religion and ethics. Through contemporary philosophical analysis it is possible to shed new light on teh status and language of religion, and in many ways the contributors to Religion and Philosophy break new ground in this perennially (...) controversial field. The collection is addressed to philosophers, theologians and anyone with a general intellectual interest in religion. Certainly it will be a valuable addition to the reading list of all teachers or students of the philosophy of religion. (shrink)

Heidegger in America explores the surprising legacy of his life and thought in the United States of America. As a critic of modern life, Heidegger often lamented the growing global influence of all things American. However, it was precisely in America where his thought inspired the work of generations of thinkers – not only philosophers but also theologians, architects, novelists, and even pundits. As a result, the reception and dissemination of Heidegger's philosophical writings transformed the intellectual and cultural history of (...) the United States at a time when American influence was itself transforming the world. A case study in the complex and sometimes contradictory process of transnational exchange, Heidegger in America recasts the scope and methods of contemporary intellectual and cultural history in the age of globalization, challenging what we think we know about Heidegger and American ideas simultaneously.

The discussion of collective agency involves the reduction problem of the concept of a collective. Individualism and Cartesian internalism have long restricted orthodox theories and made them face the tension between an irreducible concept of a collective and ontological reductionism. Heterodox theories as functionalism and interpretationism reinterpret the concept of agency and accept it as realized on the level of a collective. In order to adequately explain social phenomena that have relations as their essence, in this paper we propose a (...) relational, holistic account of collective agency and argue that functionalism and interpretationism can be integrated into such an account.

O presente texto observa a teoria crítica da sociedade desenvolvida por Habermas a partir da análise das duas teses apresentadas na Teoria da Ação Comunicativa, sobre a modernidade seletiva e sobre o desacoplamento das esferas socais tematizáveis, pretendendo compreender como o avanço dos imperativos funcionais do sistema (a burocracia administrativa estatal e a economia capitalista) têm extrapolado suas áreas de atuação e aumentado ainda mais sua dinâmica sistêmica sobre o ambito da reprodução simbólica nas sociedades capitalistas do século XXI. A (...) discussão que se segue analisará esta ampliação considerando que as interferências e alterações sobre os padrões de integração social são questões que se encontram em um desenvolvimento constante desde as mudanças pelas quais passaram a alterar os critérios de legitimação da modernidade capitalista. Ainda que de um modo não inteiramente distinto daquele tematizado por Habermas no contexto social do início dos anos 1980, pretende-se observar que que no atual estágio do capitalismo internacional esta interferência, assim como as alterações daí promovidas, tem provocado uma maior fragmentação social e gerado bloqueios que perturbam ainda mais a integração social (que ameaçam inviabilizar qualquer efetivação da emancipação social quanto mais são deturpados os critérios de legitimação e reconhecimento social). Circunscrito a este horizonte, pretende-se sustentar que tais fatores possam ser melhor compreendidos mediante uma investigação sobre as patologias sociais, especifiamente quando estas são compreendidas como parâmetros que proporcionariam identificar certa resistência a uma integração social orientada por imperativos sistêmicos.

In this article I tease out a conception of reason in Pierre-Joseph Proudhon’s writings that is both decoupled from Enlightenment notions of human nature, progress, and transcendental truth, as well as auto-critically engaged with the anti-authoritarian Enlightenment ethos of anarchist thought. In so doing, I hope to reveal how the Proudhonian deployment of reason retained a healthy skepticism of foundationalism, philosophical systems-building, and the intellectualism bred of its dogmatic excesses as well as reconsider Proudhon’s relation to our most privileged faculty.

Resehna do livro O IMPÉRIO DO DIREITO de FRANZ NEUMANN.

In recent years consciousness has become a significant area of study in the cognitive sciences. The Frontiers of Consciousness is a major interdisciplinary exploration of consciousness. The book stems from the Chichele lectures held at All Souls College in Oxford, and features contributions from a 'who's who' of authorities from both philosophy and psychology. The result is a truly interdisciplinary volume, which tackles some of the biggest and most impenetrable problems in consciousness. The book includes chapters considering the apparent explanatory (...) gap between science and consciousness, our conscious experience of emotions such as fear, and of willed actions by ourselves and others. It looks at subjective differences between two ways in which visual information guides behaviour, and scientific investigation of consciousness in non-human animals. It looks at the challenges that the mind-brain relation presents for clinical practice as well as for theories of consciousness. The book draws on leading research from philosophy, experimental psychology, functional imaging of the brain, neuropsychology, neuroscience, and clinical neurology. Distinctive in its accessibility, authority, and its depth of coverage, Frontiers of Consciousness will be a groundbreaking and influential addition to the consciousness literature. (shrink)

Argument and imagination are often interdependent. The Aesthetics of Argument is concerned with how this relationship may bear on argument's concern with truth, not just persuasion, and with the enhancement of understanding such interdependence may bring. The rationality of argument, conceived as the advancement of reasons for or against a claim, is not simply a matter of deductive validity. Whether arguments are relevant, have force, or look foolish cannot always be assessed in these terms. Martin Warner presents a series of (...) case studies which explore how analogy, metaphor, narrative, image, and symbol can be used in different ways to frame one domain in terms of another, and how criteria drawn from the study of imaginative literature may have a bearing on their truth-aptness.

A landmark discussion between two great thinkers, vital to an understanding of twentieth-century philosophy and intellectual history.

Die im Wintersemester 1929/30 an der Freiburger Universität vierstündig gehaltene Vorlesung ist in zweierlei Hinsicht erregend. Zum einen enthält sie eine breit durchgeführte Analyse der in der Freiburger Antrittsvorlesung 'Was ist Metaphysik?' nur gestreiften Langeweile, zum anderen bietet sie eine ebenso ausführliche Wesensbestimmung des Organismus und des Lebens - eine Thematik, die Heidegger in 'Sein und Zeit', § 12, nur benennt. 'Diese Vorlesung ist wohl die bedeutendste, die Heidegger gehalten hat, und schon fast ein zweites Hauptwerk.' Rüdiger Safranski.

Book description: The capacity to represent and think about time is one of the most fundamental and least understood aspects of human cognition and consciousness. This book throws new light on central issues in the study of the mind by uniting, for the first time, psychological and philosophical approaches dealing with the connection between temporal representation and memory. Fifteen specially written essays by leading psychologists and philosophers investigate the way in which time is represented in memory, and the role memory (...) plays in our ability to reason about time. They offer insights into current theories of memory processes and of the mechanisms and cognitive abilities underlying temporal judgements, and draw out fundamental issues concerning the phenomenology and epistemology of memory and our understanding of time. The chapters are arranged into four sections, each focused on one area of current research: Keeping Track of Time, and Temporal Representation; Memory, Awareness and the Past; Memory and Experience; Knowledge and the Past: The Epistemology and Metaphysics of Time. A general introduction gives an overview of the topics discussed and makes explicit central themes which unify the different philosophical and psychological approaches. (shrink)
