In the first part of this article we survey general similarities and differences between biological and social macroevolution. In the second (and main) part, we consider a concrete mathematical model capable of describing important features of both biological and social macroevolution. In mathematical models of historical macrodynamics, a hyperbolic pattern of world population growth arises from non-linear, second-order positive feedback between demographic growth and technological development. Based on diverse paleontological data and an analogy with macrosociological models, we suggest that the (...) hyperbolic character of biodiversity growth can be similarly accounted for by non-linear, second-order positive feedback between diversity growth and the complexity of community structure. We discuss how such positive feedback mechanisms can be modelled mathematically. (shrink)

In this philosophical response to Terrance MacMullan’s From American Empire to América Cósmica through Philosophy: Prospero’s Reflection (2023), I engage with his ambitious and timely project of inter-American philosophy and critique of U.S. imperialism. While analyzing and praising MacMullan's engagement with philosophers like Pedro Albizu Campos and Gloria Anzaldúa, I also reflect on our shared positionality as white scholars raised in Spanish-speaking regions of the USA. Finally, I draw upon Anzaldúa's "Geographies of Selves" concept to suggest that more "autohistoria" or (...) self-disclosure would enhance the existential depth and power of MacMullan's project of haciendo una América Cósmica through philosophy.

Professor Morales’ Coss Dialogue Lecture demonstrates the utility of pragmatism for his work as a social scientist across three projects: 1) field research studying the acephalous and heterogenous social order of Chicago’s Maxwell Street Market; 2) nascent research how unseen religious orders animate the lives of im/migrants and their contributions to food systems; and 3) large-scale longitudinal research on farmers markets using the Metrics + Indicators for Impact (MIFI) toolkit. The first two sections of my paper applaud and build upon (...) Morales’ first two projects, and my extremely brief third section raises some questions about positivist specters that may haunt the MIFI project insofar as it is conceptualized, described, and deployed using the terms favored by mainstream social science.

This encyclopedia article outlines the history of Latin American philosophy: the thinking of its indigenous peoples, the debates over conquest and colonization, the arguments for national independence in the eighteenth century, the challenges of nation-building and modernization in the nineteenth century, the concerns over various forms of development in the twentieth century, and the diverse interests in Latin American philosophy during the opening decades of the twenty-first century. Rather than attempt to provide an exhaustive and impossibly long list of scholars’ (...) names and dates, this article outlines the history of Latin American philosophy while trying to provide a meaningful sense of detail by focusing briefly on individual thinkers whose work points to broader philosophical trends that are inevitably more complex and diverse than any encyclopedic treatment can hope to capture.

This article describes my ongoing attempts to more successfully engage the full linguistic repertoires and cultural identities of undergraduate students at a “Hispanic Serving Institution” (HSI) in South Texas by teaching a bilingual Introduction to Latin American Philosophy course in the “Language, Philosophy, and Culture” area of Texas’ General Education Core Curriculum. By uncovering the diverse identities, worldviews, and languages of those who were historically excluded from the Eurocentric discipline of philosophy through the conquest and colonization of the Americas, Latin (...) American philosophers offer us new ways of thinking and living by challenging Anglocentric language, philosophy, and culture. As part of the new B3 (Bilingual, Bicultural, and Biliterate) vision of the University of Texas Rio Grande Valley, the course is designed to draw upon the richly varied bilingualisms and biliteracies of predominantly Latinx students in order to help them honor, theorize, and cultivate their bicultural identities by “philosophizing in tongues” rather than being forced to assimilate to the monolingual and monocultural ideology that prevails across both mainstream Anglophone philosophy and the system of higher education in the United States of America.

This essay fills in some historical, conceptual, and pedagogical gaps that appear in the most visible and recent professional efforts to “revive” Philosophy as a Way of Life (PWOL). I present “American Philosophy and Self-Culture” as an advanced undergraduate seminar that broadens who counts in and what counts as philosophy by immersing us in the lives, writings, and practices of seven representative U.S.-American philosophers of self-culture, community-building, and world-changing: Benjamin Franklin (1706–1790), Frederick Douglass (1818–1895), William Ellery Channing (1780–1842), Henry David (...) Thoreau (1817–1862), Margaret Fuller (1810-1850), Henry Bugbee (1915–1999), and Gloria Anzaldúa (1942–2004). Students enter the class with preconceptions about who philosophers are, what they do, how they write, and the languages in which they write. Students walk out with new senses of self, place, and language that emerge through new ways of seeing, doing, and writing philosophy. (shrink)

My essay begins by providing a broad vision of how William James’s psychology and philosophy were a two-pronged attempt to revive the self whose foundations had collapsed after the Civil War. Next, I explain how this revival was all too successful insofar as James inadvertently resurrected the imperial self, so that he was forced to adjust and develop his philosophy of religion in keeping with his anti-imperialism. James’s mature philosophy of religion therefore articulates a vision of the radically ethical saint (...) religiously bound to a decidedly pluralistic universe. I evaluate James’s philosophy of religion by comparing it to Enrique Dussel’s psychological portrait of the imperialist ego, Dussel’s attempt to religiously bind this ego, and the more radical philosophy that results. I suggest that Dussel’s philosophy of liberation: 1) better theorizes the religious contraction of the self as a necessary part of ethical and political life and 2) offers a more concrete and radically democratic philosophy. My overarching aim is to show how Dussel’s liberation philosophy can help critically develop James’s pragmatist claim that religion might provide a force for widely and positively transforming our ethical and political lives.

Our paper examines Gloria Anzaldúa’s critical appropriation of Mexican philosophical sources, especially in the writing of Borderlands/La Frontera. We demonstrate how Anzaldúa developed a transnational Philosophy of Mexicanness, effectively contributing to what has been recently characterized as the “multi-generational project to pursue philosophy from and about Mexican circumstances” (Vargas). More specifically, we recover “La Mexicana en la Chicana” by paying careful attention to Anzaldúa’s Mexican sources, both those she explicitly cites and those we have discovered while conducting archival research using (...) the Gloria Evangelina Anzaldúa Papers from the Benson Latin American Collection at the University of Texas at Austin. The three sections of our paper: 1) define the terms Mexican and philosophy in conversation with Anzaldúa’s work, 2) examine the Mexican philosophical sources that Anzaldúa cites in Borderlands/La Frontera, and 3) present the other major Mexican philosophical influences on Anzaldúa that we have found in her archive. The eight Mexican philosophical sources we discuss here include: José Vasconcelos (1882-1959), Miguel León-Portilla (1926-2019), Juana Armanda Alegría (1938- ), Octavio Paz (1914-1998), Samuel Ramos (1897-1959), Rosario Castellanos (1925-1974), Sor Juana Inés de La Cruz (1648-1695), and Jorge Carrión (1913-2005).

This essay suggests that the U.S.-American Pragmatist tradition could be fruitfully reconstructed by way of a dialogue with Latin American Liberation Philosophy. More specifically, I work to establish a common ground for future comparative work by: 1) gathering and interpreting Enrique Dussel’s scattered comments on Pragmatism, 2) showing how the concept of liberation already functions in John Dewey’s Pragmatism, and 3) suggesting reasons for further developing this inter-American philosophical dialogue and debate.

In response to those calling for philosophical dialogue across the Americas, this paper considers the historical emergence of the concept of el pueblo (“the people”) as the subject and object of democracy. The first section makes a linguistic claim: the genuinely communal nature of “the people” clearly appears when considering el pueblo because it is unambiguously singular, grammatically speaking. The second section makes a historical claim: the microhistory of a largely indigenous pueblo in Mexico’s Yucatán enables us to begin unpacking (...) the complex concrete, historical, and genealogical dimensions of el pueblo. The brief concluding section suggests that historically contextualizing and concretizing el pueblo provides conceptual support for some of the premises that underwrite Latin American philosophies of liberation, including that of Enrique Dussel. -/- .

Two fundamentally different perspectives on knowledge diffusion dominate debates about academic disciplines. On the one hand, critics of disciplinary research and education have argued that disciplines are isolated silos, within which specialists pursue inward-looking and increasingly narrow research agendas. On the other hand, critics of the silo argument have demonstrated that researchers constantly import and export ideas across disciplinary boundaries. These perspectives have different implications for how knowledge diffuses, how intellectuals gain and lose status within their disciplines, and how intellectual (...) reputations evolve within and across disciplines. We argue that highly general claims about the nature of disciplinary boundaries are counterproductive, and that research on the nature of specific disciplinary boundaries is more useful. To that end, this paper uses a novel publication and citation network dataset and statistical models of citation networks to test hypotheses about the boundaries between philosophy of science and 11 disciplinary clusters. Specifically, we test hypotheses about whether engaging with and being cited by scientific communities outside philosophy of science has an impact on one’s position within philosophy of science. Our results suggest that philosophers of science produce interdisciplinary scholarship, but they tend not to cite work by other philosophers when it is published in journals outside of their discipline. Furthermore, net of other factors, receiving citations from other disciplines has no meaningful impact—positive or negative—on citations within philosophy of science. We conclude by considering this evidence for simultaneous interdisciplinarity and insularity in terms of scientific trading theory and other work on disciplinary boundaries and communication.

Philosophers of science are increasingly arguing for the importance of doing scientifically- and socially-engaged work, suggesting that we need to reduce barriers to extra-disciplinary engagement and broaden our impact. Yet, we currently lack empirical data to inform these discussions, leaving a number of important questions unanswered. How common is it for philosophers of science to engage other communities, and in what ways are they engaging? What barriers are most prevalent when it comes to broadly disseminating one’s work or collaborating with (...) others? To what extent do philosophers of science actually value an engaged approach? Our project addresses this gap in our collective knowledge by providing empirical data regarding the state of philosophy of science today. We report the results of a survey of 299 philosophers of science about their attitudes towards and experiences with engaging those outside the discipline. Our data suggest that a significant majority of philosophers of science think it is important for non-philosophers to read and make use of their work; most are engaging with communities outside the discipline; and many think philosophy of science, as a discipline, has an obligation to ensure it has a broader impact. Interestingly, however, many of these same philosophers believe engaged work is generally undervalued in the discipline. We think these findings call for cautious optimism on the part of those who value engaged work—while there seems to be more interest in engaging other communities than many assume, significant barriers still remain.

This paper explores how an institution of higher education in partnership with a local parent-led organization can support authentic and organic Latinx family engagement and advocacy for dual language bilingual, bicultural, biliterate education (DLB3E). We reflect upon how engaging with Spanish-speaking parents helped us reimagine, reinvigorate, and transform local schools and universities by means of new understandings and practices of linguistic and cultural wealth, community assets, and family empowerment. We argue that this form of collaboration can lead to innovative and (...) positive changes in p-16 education. To demonstrate, we share our developing framework for organizing annual parent conferences hosted by the University of Texas Rio Grande Valley’s Center for Bilingual Studies in partnership with RGV PUEDE (Rio Grande Valley Parents United for Excellent Dual Education/Padres Unidos para una Educación Dual de Excelencia). Our framework shows how to build and strengthen grassroots parent and community advocacy for DLB3E from pre-kindergarten through university by strengthening partnerships between parents, public schools, university faculty, and nonprofit organizations to organize conferences and other types of public conversations in Spanish.

BOOK REVIEW: Through fifteen interrelated essays, Daniel Campos’ Loving Immigrants in America reflects upon his experiences as a Latin American immigrant to the United States and develops an experiential philosophy of personal interaction. Building upon previous work, Campos’ implicit conceptual framework comes from Charles S. Peirce’s dual philosophical accounts of the evolution of personality and evolutionary love. But the flesh and blood of the book are Campos’ own personal experiences as an immigrant who has labored for more than twenty years (...) to make himself at home in the United States, aka la Yunai, by growing to love an impressively broad range of places and people across the country. Campos begins in rural Arkansas (where he arrived as an eighteen-year-old from Costa Rica to study at a small religious liberal arts college), travels extensively across the Deep South (in a series of road trips described in Chapters 3-6), completes an MA in Statistics and later a PhD in Philosophy at Penn State, and eventually settles to teach at Brooklyn College where he is surrounded by immigrants from all over the world. The book’s cast of characters and Campos’ interactions with them are so extensive as to defy generalization, but careful readers are likely to walk away convinced of Campos’ claim that “anyone who is receptive and attentive to the commonality of human experience can empathize with immigrants” (2).

Host-microbiome interactions (HMIs) are critical for the modulation of biological processes and are associated with several diseases, and extensive HMI studies have generated large amounts of data. We propose that the logical representation of the knowledge derived from these data and the standardized representation of experimental variables and processes can foster integration of data and reproducibility of experiments and thereby further HMI knowledge discovery. A community-based Ontology of Host-Microbiome Interactions (OHMI) was developed following the OBO Foundry principles. OHMI leverages established (...) ontologies to create logically structured representations of microbiomes, microbial taxonomy, host species, host anatomical entities, and HMIs under different conditions and associated study protocols and types of data analysis and experimental results.

A reading is offered of Carl Hempel’s and Thomas Kuhn’s positions on, and disagreements about, rationality in science that relates these issues to the debate between W.V. Quine and Rudolf Carnap on the analytic/synthetic distinction.

What is W. V. O. Quine’s relationship to classical pragmatism? Although he resists the comparison to William James in particular, commentators have seen an affinity between his “web of belief” model of theory confirmation and James’s claim that our beliefs form a “stock” that faces new experience as a corporate body. I argue that the similarity is only superficial. James thinks our web of beliefs should be responsive not just to perceptual but also to emotional experiences in some cases; Quine (...) denies this. I motivate James’s controversial view by appealing to an episode in the history of medicine when a researcher self-experimented by swallowing a vial of bacteria that at the time had not been studied in much detail. The researcher’s commitment to his own as-yet untested hypothesis was based in part on emotional considerations. Finally, I argue that Quine’s insistence that emotions can never be relevant to adjusting our web of belief reflects a tacit holdover of one of logical positivism’s crucially anti-pragmatist commitments—that philosophy of science should focus exclusively on the context of justification, not the context of discovery. James’s emphasis on discovery as a (perhaps the) crucial locus for epistemological inquiry is characteristic of pragmatism in general. Since Quinean epistemology is always an epistemology of justification, he is not happily viewed as a member of the pragmatist tradition. (shrink)

G. Hegel in his Introduction to the History of Philosophy limits the initiation of this study to the field of the kind of thinking that emerged in Greece in the S. V ac, starting to do it that in other traditions (in which states, the Taoism, the religion of the Vedas, the Buddhism), the thinking is not autonomus in relation to a religious, mystical, mythological or customs justifications. Therefore there is no thought free of external determinations in these traditions. This (...) Hegelian principle has been accepted by the vast majority of those who carry out the study on the origin and history of philosophy. This paper intends to point out, following comments from experts in the field, how in certain traditions of Indian philosophy defined as nastika darshanas, and taking the Cārvāka materialism as example, philosophical thought occurs free from external determinations (religious, mythological, etc.), without prejudice to those philosophical systems which have been useful when justifying or discredit certain positions in these branches of human action.

"In the programs of Logic and History of Philosophy in the FHUCE study and introduction to logic is always done on the basis of Western classical Greek tradition, and its development is still exclusively through Western culture. This presentation aims to provide a path parallel to the West is the tradition of Nyaya-Vaisesika schools, which arise in the S. V B.C. like a response to the anti-Vedic Buddhist nihilism, and reached an important technical development at the beginning of S. II (...) D.C. when you know the Nyāyasutras attributed to Aksapada Gautama, and are considered the founding text of Nyāya tradition of Indian philosophy. The great virtue of the achievement of these schools is that although the system has Vaisesika been described as "a synthesis between philosophy of nature, ethics and soteriology" , which also applies to school Nyāya in the latter we are also a great emphasis on epistemology and the rules must be observed in philosophical debates. In their synthesis, Nyāya -Vaisesika system gets his language and jargon will be adopted by all who wish to discuss logical issues in India (especially in discussions Vedanta / Buddhism) without the need to adopt such language should assume his ontological, moral and religious premises.

What comes after postmodernism? There are many answers to this question. In Alexander Pavlov's book ‘Post-postmodernism. How Social and Cultural Theories Explain Our Time’ a philosophical arbitration is conducted to reveal a legitimate description of our cultural epoch.

In particular, arguments are given in favor of the fact that Pavlov's position does not depend on Frederick Jameson's theory, and the author himself does not (...) find convincing ways to show Jameson's fundamental importance for contemporary theories of culture.

In this work we study dimensional theoretical properties of some a±ne dynamical systems. By dimensional theoretical properties we mean Hausdor® dimension and box- counting dimension of invariant sets and ergodic measures on theses sets. Especially we are interested in two problems. First we ask whether the Hausdor® and box- counting dimension of invariant sets coincide. Second we ask whether there exists an ergodic measure of full Hausdor® dimension on these invariant sets. If this is not the case we ask the (...) question, whether at least the variational principle for Haus- dor® dimension holds, which means that there is a sequence of ergodic measures such that their Hausdor® dimension approximates the Hausdor® dimension of the invariant set. It seems to be well accepted by experts that these questions are of great importance in developing a dimension theory of dynamical systems (see the book of Pesin about dimension theory of dynamical systems [PE2]). Dimensional theoretical properties of conformal dynamical systems are fairly well understood today. For example there are general theorems about conformal repellers and hyperbolic sets for conformal di®eomorphisms (see chapter 7 of [PE2]). On the other hand the existence of two di®erent rates of expansion or contraction forces problems that are not captured by a general theory this days. At this stage of de- velopment of the dimension theory of dynamical systems it seems natural to study non conformal examples. This is the ¯rst step to understand the mechanisms that determine dimensional theoretical properties of non conformal dynamical systems. A±ne dynamical systems represent simple examples of non conformal systems. They are easy to de¯ne, but studying their dimensional theoretical properties does never- theless provide challenging mathematical problems and exemplify interesting phe- nomena. We consider here a special class of self-a±ne repellers in dimension two, depending on four parameters (see 2.1.). Furthermore we study a class of attractors of piecewise a±ne maps in dimension three depending on four parameters as well. The last object of our work are projections of these maps that are known as gener- alized Baker's transformations (see 2.2.). The contents of our work is the following: In chapter two we give an overview about some main results in the area of di- mension theory of a±ne dynamical systems and de¯ne the systems we study in this work. We will explain, what is known about the dimensional theoretical properties of these systems and describe what our new results are. In chapter three we then apply symbolic dynamics to our systems. We will introduce explicit shift codings 4 and ¯nd representations of all ergodic measures for our systems using these codings. From chapter four to chapter eight we study dimensional theoretical properties, which our systems generally or generically have. In chapter four we will prove a formula for the box-counting dimension of the repellers and the attractors (see the- orem 4.1.). Then in chapter ¯ve we apply general dimensional theoretical results for ergodic measures found by Ledrappier and Young [LY] and Barreira, Schmeling and Pesin [BPS] to our systems. These results relate the dimension of ergodic measures to metric entropy and Lyapunov exponents. Using this approach we will be able to reduce questions about the dimension of ergodic measures in our context to ques- tions about certain overlapping and especially overlapping self-similar measures on the line. These overlapping self-similar measures are studied in chapter six. Our main theorem extends a result of Peres and Solomyak [PS2] concerning the absolute continuity resp. singularity of symmetric self-similar measures to asymmetric ones (see theorem 6.1.3.). In chapter seven we bring our results together. We prove that we generically (in the sense of Lebesgue measure on a part of the parameter space) have the iden- tity of box-counting and Hausdor® dimension for the repellers and the attractors. (see theorem 7.1.1. and corollary 7.1.2.). This result suggest that one can expect that the identity of box-counting dimension and Hausdor® dimension holds at least generically in some natural classes of non conformal dynamical systems. Furthermore we will see in chapter seven that there generically exists an ergodic measure of full Hausdor® dimension for the repellers. On the other hand the vari- ational principle for Hausdor® dimension is not generic for the attractors. It holds only if we assume a certain symmetry (see theorem 7.1.1.). For generalized Baker's transformations we will ¯nd a part of the parameter space where there generically is an ergodic measure of full dimension and a part where the variational principle for Hausdor® dimension does not hold (see theorem 7.1.3.). Roughly speaking the reason why the variational principle does not hold here is, that if there exists both a stable and an unstable direction one can not generically maximize the dimension in the stable and in the unstable direction at the same time. In an other setting this phenomenon was observed before by Manning and McCluskey [MM]. In chapter eight we extend some results of the last section to invariant sets that correspond to special Markov chains instead of full shifts (see theorem 8.1.1.). In the last two chapters of our work we are interested in number theoretical excep- tions to our generic results. The starting point of our considerations in section nine are results of ErdÄos [ER1] and Alexander and Yorke [AY] that establish singularity and a decrease of dimension for in¯nite convolved Bernoulli measures under special conditions. Using a generalized notion of the Garsia entropy ([GA1/2]) we are able 5 to understand the consequences of number theoretical peculiarities in broader class of overlapping measures (see theorem 9.1.1.). In chapter ten we then analyze number theoretical peculiarities in the context of our dynamical systems. We restrict our attention to a symmetric situation where we generically have the existence of a Bernoulli measure of full dimension and the identity of Hausdor® and box-counting dimension for all of our systems. In the ¯rst section of chapter ten we ¯nd parameter values such that the variational principle for Hausdor® dimension does not hold for the attractors and for the Fat Baker's transformations (see theorem 10.1.1.). These are the ¯rst known examples of dynamical systems for which the variational principle for Hausdor® dimension does not hold because of number theoretical peculiarities of parameter values. For the repellers we have been able to show that under certain number theoretical conditions there is at least no Bernoulli measure of full Hausdor® dimension; the question if the variational principle for Hausdor® dimension holds remains open in this situation. In the second section of chapter ten we will show that the identity for Hausdor® and box-counting dimension can drops because there are number theoretical pecu- liarities. In the context of Weierstrass-like functions this phenomenon was observed by Przytycki and Urbanski [PU]. Our theorem extends this result to a larger class of sets, invariant under dynamical systems (see theorem 10.2.1). At the end of this work the reader will ¯nd two appendices, a list of notations and the list of references. In appendix A we introduce the notions of dimension we use in this work and collect some general facts in dimension theory. In appendix B we state the facts about Pisot-Vijayarghavan number, we need in our analysis of number theoretical peculiarities. The list of notations contains general notations and a table with a summary of notations we use to describe the dynamical systems that we study.

The notion of a physiological individuals has been developed and applied in the philosophy of biology to understand symbiosis, an understanding of which is key to theorising about the major transition in evolution from multi-organismality to multi-cellularity. The paper begins by asking what such symbiotic individuals can help to reveal about a possible transition in the evolution of cognition. Such a transition marks the movement from cooperating individual biological cognizers to a functionally integrated cognizing unit. Somewhere along the way, did (...) such cognizing units simultaneously have cognizers as parts? Expanding upon the multiscale integration view of the Free Energy Principle, this paper develops an account of reciprocal integration, demonstrating how some coupled biological cognizing systems, when certain constraints are met, can result in a cognizing unit that is in ways greater than the sum of its cognizing parts. Symbiosis between V. Fischeri bacteria and the bobtail squid is used to provide an illustration this account. A novel manner of conceptualizing biological cognizers as gradient is then suggested. Lastly it is argued that the reason why the notion of ontologically nested cognizers may be unintuitive stems from the fact that our folk-psychology notion of what a cognizer is has been deeply influenced by our folk-biological manner of understanding biological individuals as units of reproduction.

REPRODUÇÃO EM NOVILHAS LEITEIRAS -/- INTRODUÇÃO -/- O principal objetivo da criação de substitutos em gado leiteiro é produzir uma novilha que tenha seu parto aos dois anos de idade (23 a 25 meses) e com um peso de 550 a 580 kg. O manejo reprodutivo das novilhas começa quando estas atingem 14 ou 15 meses de idade e um peso de 350 a 370 kg. A produção de novilhas deve ser suficiente para substituir as vacas descartadas anualmente (25 a (...) 35%), e para contribuir com o crescimento do rebanho. Espera-se que em um gado leiteiro deva haver uma população de animais de reposição, desde um dia de vida até à fase de novilha ao parto, correspondendo pelo menos a 70 % do total das vacas (figura 1). -/- Figura 1: A meta do programa de produção de substitutos ou fêmeas de reposição consiste em uma novilha que chegue ao seu primeiro parto aos 24 ou 25 meses de idade, entre um peso de 550 a 580 kg. Elaborado pelo autor. -/- A produção de novilhas depende basicamente de três fatores: da fertilidade das vacas, ou seja, do número de bezerras nascidas anualmente; da mortalidade durante a criação e desenvolvimento; e da eficiência reprodutiva das novilhas. O manejo reprodutivo moderno das novilhas é orientado para a utilização da inseminação artificial, seja em um estro natural ou sincronizado. As novilhas representam a população animal geneticamente mais avançada no rebanho, portanto, o mérito genético de suas crias obtidas por inseminação é maior do que o das crias das vacas adultas. Além disso, as crias das novilhas obtidas mediante a inseminação aceleram o avanço genético, uma vez que contribuem com uma proporção maior de substituições do rebanho em comparação com as crias das vacas de outras faixas etárias. Além disso, as novilhas são as fêmeas mais férteis do rebanho (porcentagem de concepção: 60 a 70% vs 30 a 40% em vacas), pelo que o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. -/- 1. PUBERDADE -/- A puberdade é definida como a fase de desenvolvimento em que a fêmea apresenta o seu primeiro estro fértil. Regularmente as novilhas leiteiras, sob condições ótimas de manejo, chegam à puberdade entre 11 e 12 meses de idade, ou seja, antes de alavancar o peso recomendado para receber o primeiro serviço. Vale salientar que as novilhas podem ficar gestantes após a puberdade; no entanto, isto não é conveniente porque ainda não completou-se o seu desenvolvimento. Se ficarem gestantes nos primeiros ciclos estrais, as novilhas poderiam chegar ao parto com pouco desenvolvimento físico, o que provocaria distocias e baixa produção de leite (figura 2). A ativação do sistema neuroendócrino para que a bezerra atinja a puberdade é regulada principalmente pelo estado nutricional (condição corporal). A transição do anestro pré-puberal à ciclicidade puberal coincide com um aumento da condição corporal e das concentrações de insulina, IGF-I e leptina. Estes hormônios agem como sinais metabólicos no hipotálamo e hipófise que modificam a frequência de secreção das gonadotropinas, resultando na maturação folicular e ovulação. O atraso em relação à puberdade está diretamente relacionado com deficiências na alimentação; esta condição verifica-se em criações pouco tecnificadas, principalmente de pequenos e médios produtores. As novilhas que já atingiram o peso para receber o primeiro serviço e não apresentaram estro, devem ser examinadas por via retal para excluir possíveis anormalidades do desenvolvimento, tais como freemartinismo ou hipoplasia genital. -/- Figura 2: O fator mais importante que determina a puberdade é a nutrição. Bezerras bem alimentadas apresentam ciclos estrais aos 11 meses de idade e devem ser inseminadas aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. Acervo pessoal do autor. -/- 2. DETECÇÃO DE ESTRO E INSEMINAÇÃO ARTIFICIAL -/- A baixa eficiência na detecção de estros é o problema que mais afeta a eficiência reprodutiva das novilhas. De acordo com a duração do estro (8 a 18 horas), a observação das novilhas em períodos de 30 minutos durante a manhã e à tarde, permite detectar em estro até 70% das fêmeas, enquanto a observação contínua (24 horas) aumenta a eficiência na detecção até 95% (figuras 3 e 4). No manejo tradicional dos rebanhos leiteiros, as novilhas recebem pouca atenção por parte dos trabalhadores, o que resulta em baixa eficiência na detecção de estros (50 a 60%). Em diferença das vacas adultas em lactação, as novilhas estão menos expostas a fatores que diminuem a expressão do estro, portanto, com uma rotina de observação, de pelo menos duas horas na manhã (6h a 8h da manhã) e duas horas pela tarde até a noite (17h da tarde a 19h da noite), pode-se detectar até 90% das fêmeas no estro (figura 5). -/- Figura 3: O fator que mais influencia a idade ao primeiro parto é a baixa eficiência na detecção de estros, pelo que é recomendável a observação de estros com pessoal qualificado, em períodos de pelo menos duas horas pela manhã e duas à tarde. Acervo pessoal do autor. -/- Figura 4: Com a observação contínua é possível alcançar de 90 a 95% de eficiência na detecção de estros. Acervo pessoal do autor. -/- Figura 5: A inseminação deve ser realizada durante o período de receptividade sexual. Com boa eficiência na detecção de estros, a inseminação pode ser praticada no programa AM-PM e PM-AM, ou em apenas um turno de inseminação pela manhã (10:00), com bons resultados. -/- 3. TAXA DE PRENHEZ -/- O melhor indicador de eficiência reprodutiva é a taxa de prenhez. Este indicador refere-se à proporção de animais gestantes do total elegível para inseminação, num período equivalente a um ciclo estral. Como já se descreveu no trabalho Fisiologia do Estro e do Serviço na Reprodução Bovina, este indicador considera a eficiência na detecção de estros e a porcentagem de concepção, e reflete com maior objetividade a eficácia do manejo reprodutivo. Este parâmetro pode ser melhorado através de um aumento da proporção de novilhas detectadas em estro, o que se obtém aumentando o tempo de observação e aplicando técnicas de sincronização do estro (figura 6). -/- 4. INSEMINAÇÃO DE NOVILHAS COM SÊMEN SEXADO -/- A utilização de sêmen sexado é uma boa opção para a produção de novilhas de reposição. Com a nova tecnologia disponível para a separação de espermatozoides com o cromossomo x, é possível alcançar até 90% de crias fêmeas; no entanto, o processo de separação de espermatozoides tem baixa eficiência, o que limita o número de espermatozoides por palheta. As palhetas de inseminação com sêmen sexado contém de dois a três milhões de espermatozoides (doses de sêmen não sexado têm de 20 a 30 milhões). De acordo com os dados de fertilidade de gados comerciais, as novilhas inseminadas com sêmen sexado mostram de 10 a 20% menor concepção que novilhas inseminadas com sêmen não sexado, o que desencoraja o seu uso. Causas de baixa fertilidade não são conhecidas, no entanto, estão associadas com a menor concentração espermática e com alguns danos nos espermatozoides provocados pelo processo de separação. No entanto, o uso de sêmen sexado é uma opção viável para aumentar a produção de novilhas no rebanho, e com o melhoramento dos processos de separação espermática em pouco tempo se converterá em uma prática de rotina nos estábulos (figura 7). -/- Figura 6: Uma técnica que aumenta a eficiência na detecção dos estros consiste em pintar a região da grupa. Quando esta pintura desaparece ou se nota que as novilhas estão "talhadas", devem ser apalpadas via retal para determinar se existem sinais genitais de estro. Acervo pessoal do autor. -/- Figura 7: As novilhas são as fêmeas mais férteis do rebanho, por isso o custo do sêmen por gestação é menor em comparação com as vacas adultas, o que permite investir em melhores touros e em sêmen sexado. Acervo pessoal do autor. 5. MONTA DIRIGIDA -/- A monta dirigida ou direta é uma opção prática e eficaz para emprenhar as novilhas. Neste sistema se introduz um touro com um grupo de novilhas, para que ele se encarregue de encontrar as fêmeas em estro e proceder a monta. Em rebanhos comerciais, o ideal é a utilização de um touro para 25 fêmeas. No entanto, com este manejo perde-se a oportunidade de utilizar a inseminação artificial e, com isso, a possibilidade de melhoria genética. -/- 6. PROGRAMAS DE SINCRONIZAÇÃO DE ESTROS -/- Os tratamentos para sincronizar o estro das novilhas possuem os mesmos fundamentos que os utilizados nas vacas. -/- 6.1 Prostaglandina F2a -/- A PGF2α é utilizada para a sincronização de estros em grupos de novilhas, e também é utilizada para a indução do estro individualmente, nas fêmeas que são examinadas por via retal e têm um corpo lúteo. A resposta dos animais tratados é variável; em novilhas pode-se alcançar até 95% de animais em estro. O tempo de manifestação do estro após a injeção é de 48 a 120 horas. -/- 6.1.1 Dupla injeção de PGF2a -/- Além da sincronização dos animais selecionados pela presença de um corpo lúteo diagnosticado por palpação retal, existem dois programas que não incluem a palpação retal. Por exemplo, na segunda-feira, ou no dia preferido, injeta-se PGF2α em todas as novilhas que se deseja inseminar. Cerca de 50% das novilhas manifestarão estro nas próximas 48 a 120 horas. As fêmeas que não mostrarem estro receberão uma segunda injeção na segunda-feira seguinte (intervalo de sete dias). As que apresentaram estro com a primeira injeção teriam um corpo lúteo nesse momento, enquanto as que não o manifestaram estavam em estro ou em metaestro; assim, ao repetir o tratamento sete dias depois, estas últimas novilhas teriam um corpo lúteo e responderiam à PGF2α (figura 8). No outro programa, é administrada duas doses de PGF2α com 11 dias de separação/intervalo. As novilhas podem ser inseminadas no estro observado, após qualquer uma das duas injeções. Este programa oferece uma boa sincroniza- ção após a segunda injeção e é o programa de escolha na sincronização das novilhas receptoras de embriões (figura 9). -/- Figura 8: Sincronização do estro com dupla injeção de PGF2a com 7 dias de diferença/intervalo. Elaborado pelo autor. -/- Figura 9: Sincronização do estro com dupla injeção de PGF2a com 11 dias de diferença/intervalo. Elaborado pelo autor. -/- 6.2 Progestágenos -/- Existe um tratamento que consiste na inserção, na parte externa da orelha, de um implante que contém norgestomet, que permanece na região auricular por nove dias. Além disso, o tratamento é complementado com a injeção intramuscular de valerato de estradiol e norgestomet, no momento da colocação do implante. O tempo de apresentação do estro a partir da remoção do implante é de 48 a 72 horas e a proporção de animais em estro muitas vezes se torna maior do que 80%. Outro tratamento é baseado na inserção intravaginal de dispositivos de liberação de progesterona. O dispositivo pode ser utilizado durante 12 dias ou o período de exposição pode ser encurtado, desde que seja acompanhado da injeção de uma dose luteolítica de PGF2α, um dia antes ou no momento da remoção do dispositivo. A fertilidade global conseguida após o serviço no estro sincronizado é similar à obtida no estro natural; porém, algumas novilhas são menos férteis, o que está associado com alterações no desenvolvimento folicular e alterações na relação temporal entre o estro e a ovulação. Observou-se que o tratamento com implantes de norgestomet combinados com a injeção de valerato de estradiol pode induzir comportamento estral em animais que não estão ciclando normalmente. Isso ocorre porque os níveis de estradiol, administrados no primeiro dia, persistem até o momento da remoção do implante. Assim, ao remover a fonte do progestágeno e ao haver concentrações altas de estradiol se desencadeia o estro, o qual em novilhas anéstricas não é acompanhado de ovulação, enquanto que em novilhas ciclando se altera a relação temporal entre o estro, pico pré-ovulatório de LH e ovulação. Bons resultados são alcançados quando o valerato de estradiol não é administrado e é substituído por uma injeção de PGF2α no momento da remoção do implante. Outro fator que tem sido associado com baixa fertilidade é o dia do ciclo em que o tratamento começa. Observou-se que quando coincide com a presença de um corpo lúteo (diestro), a porcentagem de concepção é maior do que quando não há um corpo lúteo (proestro). Isto ocorre porque a concentração sérica do progestágeno, por si só, não é capaz de suprimir a secreção pulsátil de LH, o que faz com que o folículo dominante presente no momento de iniciar o tratamento não sofra atresia e persista até o dia da retirada do progestágeno, convertendo-se no folículo ovulatório. Com isso, o folículo já envelheceu e o ovócito já sofreu alterações que reduzem o seu potencial para desenvolver um embrião viável. Quando o tratamento coincide com a presença de um corpo lúteo, a secreção de LH é efetivamente suprimida devido ao efeito aditivo da progesterona secretada pelo corpo lúteo e do progestágeno exógeno, inserido na vaca, o que provoca a reposição folicular. Em condições de campo, a seleção das vacas pela presença de um corpo lúteo antes de iniciar o tratamento com progestágenos é impraticável, uma vez que não é possível visualizá-lo, além disso essa prática/seleção não faria sentido, já que seria mais fácil tratar estes animais com dose ou doses de PGF2α. Atualmente existem tratamentos para eliminar folículos dominantes e promover uma nova onda folicular. -/- 6.3 Progestágenos orais -/- O acetato de melengestrol (MGA) é um progestágeno administrado por via oral. Em fêmeas bovinas é utilizado para melhorar a eficiência alimentar nos currais de engorda, o que se consegue através da inibição da apresentação do estro. Como todos os progestágenos, o MGA inibe a secreção de LH, eliminando assim a maturação do folículo e a ovulação. Após a remoção do MGA, o folículo dominante termina o seu desenvolvimento e as fêmeas apresentam estro em forma sincronizada. A dose de MGA por novilha é de 0,5 a 1 mg por dia, em tratamentos que variam de 9 a 14 dias. A apresentação comercial de MGA contém 0,22 mg do hormônio por 1 g do produto. O MGA pode ser facilmente misturado com qualquer concentrado ou grão moído. Após o último dia de tratamento, o estro se apresenta de dois a seis dias. O intervalo de remoção do MGA ao estro é mais longo quando comparado com outros progestágenos. Isto deve-se ao tempo de remoção do MGA, uma vez que enquanto um implante ou dispositivo intravaginal é removido abruptamente, o MGA pode continuar a ser absorvido enquanto é removido do trato gastrointestinal. Com tratamentos de 14 dias podem-se obter porcentagens de concepção menores em comparação com o estro natural, o que se deve em grande parte à ovulação de folículos persistentes. Um tratamento eficaz, que também melhora a fertilidade, consiste na administração de MGA durante 14 dias, seguido de uma injeção de PGF2α 15 ou 17 dias após a remoção do progestágeno. Com este programa, uma alta proporção de fêmeas teriam um corpo lúteo no momento da injeção da PGF2α e apresentariam estro com boa sincronização. Outro tratamento eficaz consiste na administração do MGA durante nove dias, mais uma dose de PGF2α ao nono dia; com este programa também se obtêm bons resultados em sincronização do estro e fertilidade. Este tratamento foi avaliado com novilhas holandesas e a porcentagem de fêmeas sincronizadas é elevada (95%). A porcentagem de concepção é semelhante à obtida no estro natural. Estes resultados são comparáveis aos obtidos com outros programas, como implantes de norgestomet ou dispositivos intravaginais de liberação de progesterona, mas com um custo significativamente menor (figura 10). -/- 6.4 Sincronização da ovulação e inseminação em tempo fixo -/- Em contraste com o observado em vacas em lactação, a resposta das novilhas aos programas de sincronização da ovulação e inseminação a tempo fixo é deficiente, o que se reflete em porcentagens de concepção de 20 a 35% menores que as novilhas inseminadas no estro natural. A causa desta resposta está relacionada com diferenças no desenvolvimento folicular; assim, nas novilhas o tempo de desenvolvimento do folículo dominante é mais rápido e o tempo de domínio é mais curto do que nas vacas em lactação. Desta forma, o folículo da onda folicular sincronizada com a injeção de GnRH sofre atresia antes da injeção de PGF2α, de tal forma que quando se induz a ovulação com a segunda injeção de GnRH, as novilhas têm folículos em diferentes estádios de desenvolvimento, o que provoca assincronia entre a ovulação e a inseminação artificial. -/- Figura 10: Programa de sincronização do estro com Acetato de Melengestrol (MGA). Elaborado pelo autor. -/- 7. MANEJO DO ANESTRO -/- Uma vez que as novilhas atingem a puberdade, apresentam ciclos estrais em intervalos de 21 dias que só são interrompidos pela gestação ou por alguma patologia. O anestro patológico é raro em novilhas; no entanto, surgem casos de piometra e cistos luteinizados, que são tratados com uma dose de PGF2α. Também se observam anormalidades de desenvolvimen- to, tais como freemartinismo e hipoplasia genital, patologias que não têm tratamento; somente 8% das novilhas freemartin são férteis. O anestro funcional (as novilhas manifestam estro, mas não são detectadas) é frequen- te e está diretamente relacionado com a eficiência na detecção de estros. As novilhas com idade e peso para se integrarem no programa reprodutivo e não apresentarem sinais de estro devem ser examinadas retalmente para diagnosticar a causa do anestro. Se, durante a palpação retal, as novilhas tiverem um corpo lúteo são tratadas nesse momento com PGF2α, os animais sem corpo lúteo podem receber uma injeção de PGF2α, sete dias depois. Este programa sincroniza o estro e aumenta a probabilidade de o detectar (figura 11). -/- Figura 11: As novilhas com idade e peso para se integrarem no programa reprodutivo e não mostrarem sinais de estro devem ser verificadas via retal para diagnosticar a causa do anestro. Arquivo pessoal do autor. -/- 8. MANEJO DA NOVILHA INFÉRTIL -/- A fertilidade das vacas leiteiras diminuiu nos últimos 30 anos, enquanto a fertilidade das novilhas não se alterou; após a primeira inseminação, entre 60 e 70% das novilhas emprenham. O objetivo do programa reprodutivo é conseguir que 90% das novilhas gestem nos primeiros três serviços. Desta forma, esta proporção de animais daria à luz antes dos 25 meses de idade. É comum que 10% das novilhas se transformem em animais repetidores, ou seja, novilhas com mais de três serviços inférteis. A causa da falha na concepção de novilhas deve-se principalmente à morte embrionária precoce. Uma causa importante da falha na concepção das novilhas repetidoras são as patologias adquiridas no aparelho reprodutivo; é comum encontrar aderências ovarianas e salpingite. Provavelmente, esses problemas são consequência de alguma infecção adquirida durante a criação. Diversos tratamentos hormonais têm sido testados para resolver o problema de infertilidade em novilhas repetidoras e os resultados obtidos ainda são deficientes. Como estes tratamentos não apresentam resultados consistentes, a melhor forma de mitigar o problema de infertilidade nas novilhas é melhorando as práticas de inseminação, ou seja, o momento da inseminação, o manejo do sêmen e a técnica de inseminação empregada. Além disso, a melhor técnica para aumentar a proporção de novilhas prenhes no rebanho é aumentar a eficiência da detecção de estros. -/- 9. RESUMO -/- As novilhas devem parir aos dois anos de idade (23 a 25 meses). O peso ao parto deve ser de 550 a 580 kg. O manejo reprodutivo começa aos 14 ou 15 meses de idade, com um peso de 350 a 370 kg. As palhetas de sêmen sexado contêm de 2 a 3 milhões de espermatozoides. As doses de sêmen não sexado contêm de 20 a 30 milhões de espermatozoides. A porcentagem de concepção das novilhas inseminadas com sêmen sexado é 10 a 20% menor do que com sêmen não sexado. Com sêmen sexado se obtém entre 90 e 95% de fêmeas. A porcentagem de concepção com programas de IATF é de 20 a 35% menor que nas novilhas inseminadas no estro natural. Cerca de 90% das novilhas devem ficar prenhes nos primeiros três serviços. Devem ser produzidas novilhas para substituir as vacas que são descartadas anualmen- te (25 a 35%). Espera-se que um gado leiteiro tenha ao dispor uma população de animais de reposição, desde um dia de vida até a etapa de novilha ao parto, correspondente a, pelo menos, 70 % do total das vacas. -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- AUAD, Alexander Machado et al.

Contemporary work on Boethius' Consolation of Philosophy often overlooks a discussion in CP.V.3 of a Peripatetic strategy for dissolving theological fatalism. Boethius’ treatment of this strategy and the lesson it provides about divine foreknowledge requires a reorientation of our understanding of the Consolation text. The result is that it is not foreknowledge nor any other temporally-conditioned knowledge that motivates Boethian concern but divine knowledge simpliciter.

This essay focuses on theories of creativity from six historical figures, while noting comparisons to several others. In Ancient Greece: (i) Plato advances the thesis that the poet is a passive vessel inspired by a muse. (ii) Aristotle replies with the antithesis that the poet creates through skilled activity. (iii) Longinus provides the synthesis. Plato is right that poets are passively inspired with original ideas – though the source is natural genius instead of some muse. But Aristotle is also right (...) that the poet must actively employ skill. In early modern Europe: (iv) Margaret Cavendish argues that through creativity women can enjoy some freedom and happiness despite oppression. (v) Alexander Gerard and Immanuel Kant both inherit the Longinian synthesis. Gerard says we form original ideas through remote associations. (vi) Kant notices that although the genius must be passive in the origination of ideas, she must also be active in the very same process, because she merits acclaim for her originality. Kant designs his theory of genius to resolve this Paradox of Creative Agency. (shrink)

This mainly historical paper provides a comprehensive discussion of the (heretoforth neglected) evidence of Peripatetic syllogistic in Sextus Empiricus. The paper sets out to show that it is likely that in Sextus (and Apuleius) there is valuable evidence of a transitional period in later ancient logic that is marked out as such by a number of characteristics, which include the following: (i) A Peripatetic term ‘categorical syllogism’ is newly in use, but no term ‘hypothetical syllogism’ has been established yet. (ii) (...) Stoic and Peripatetic logic are treated as complementing each other. (iii) The reversion of quantified propositions from predicate-subject to subject-predicate formulation is still fairly new. (iv) The so-called crocodile example is used to show that induction lacks the feature of concluding by necessity that is a defining mark of Aristotelian syllogisms. (v) The use of the expression katholikê protasis for categorical universal premise-propositions is distinctive of the period. (vi) The argument forms displayed by Sextus’ three examples appear to be indirectly related to the soon-to-appear Platonist hypothetical syllogistic. (vii) There are parallels that suggest that Sextus’ source belongs to the same historical period of logic as Apuleius’ source and as some probably recent source of Alexander of Aphrodisias’ Prior Analytics commentary (that is presented along with some later views and arguments, which may include Alexander’s own). Small differences between the three authors show that Sextus did not draw from the Greek handbook that was Apuleius’ source. (shrink)

No final do manuscrito, que atualmente se encontra no Museu Britânico, Berkeley registrou a data de 11 de janeiro de 1707/8. Berkeley tinha então 23 anos de idade. Isso indica que este discurso, próximo dos sermões que depois ele viria a escrever, foi escrito antes de ser (...) ordenado diácono da Igreja da Irlanda na capela do colégio do Trinity College de Dublin em 19 de fevereiro de 1709.

The first beginnings of modern logic in Croatia are recognizable as early as in the middle of the 19th century in Vatroslav Bertić. At the turn of the 20th century, Albin Nagy, who was teaching in Italy, made contributions to algebraic logic and to the philosophy of logic. At that time, a distinctive author Mate Meršić stood out, also working on algebraic logic. In the Croatian academic philosophy, until the publication of Gajo Petrović's textbook (1964) and the contributions by Heda (...) Festini, a critical or indifferent attitude toward modern logic prevailed. The first comprehensive modern logic textbook in Croatian was written by mathematician Vladimir Devidé (1964), known, for example, for his axiomatizations of natural numbers and classical propositional logic. In the Croatian philosophy of the 1980s and 1990s, influential logicians are Goran Švob and mathematician Zvonimir Šikić. At the turn of the 21st century, logical investigations are being intensified and extended to various branches of the contemporary logic. (shrink)

U članku se promatraju osnovne karakteristike razvojne dinamike hrvatskoga logičkoga nazivlja od izlazka Pacelove Logike za gimnazije, prve sustavne logike na hrvatskome jeziku, 1868. godine, pa sve do Petrovićeve Logike, također za srednja učilišta, iz 1964., koja je još uviek u uporabi. Nazivlje je u tu svrhu razvrstano u nekoliko tipičih skupina. Općenito, uočava se porast zastupljenosti latinizama (i grecizama) na štetu hrvatskih naziva. U analizi nazivlja autor se ograničuje na knjige namienjene nastavi logike bilo na srednjim učilištima, bilo na (...) sveučilištu, i to na nazivlje tradicionalne logike. Mjestimice su pridodane i napomene o nazivlju moderne (matematičke) logike. (shrink)

In this paper I analyze constitution embodiment, a particular conception of embodiment. Proponents of constitution embodiment claim that the body is a condition of the constitution of entities. Constitution embodiment is popular with phenomenologically-inspired Embodied Cognition, including research projects such as Enactivism and Radical Embodied Cognitive Science. Unfortunately, PEC’s use of constitution embodiment is neither clear nor coherent; in particular, PEC uses the concept of constitution embodiment so that a major inconsistency is entailed. PEC conceives of the body in a (...) transcendental sense as a condition of the constitution of entities, and, in an ontic sense, as a scientifically describable entity. Yet, a condition of the constitution of entities cannot be itself an entity—rather, it is the very condition of the possibility of an entity. This inconsistency entails further problems, among them PEC’s misguided focus on the location of the embodied mind. In order to correct these mistakes, I develop a conception of constitution embodiment based on the work of Heidegger, Husserl and to a lesser degree Merleau-Ponty. This has two purposes. First, it provides the conceptual groundwork to secure the status of PEC as a consistent and coherent research project and to clarify PEC’s conception of the relationship between phenomenology and the sciences. In that spirit, my approach provides further guidelines for fruitful research alliances between PEC and other research programs such as Grounded Cognition and identifies current research alliances, such as those with Radical Enactivism, as undesirable. Second, my account provides an elaborate concept of constitution embodiment that can function as the basis for more sophisticated work in the future. (shrink)

Can there be grounding without necessitation? Can a fact obtain wholly in virtue of metaphysically more fundamental facts, even though there are possible worlds at which the latter facts obtain but not the former? It is an orthodoxy in recent literature about the nature of grounding, and in first-order philosophical disputes about what grounds what, that the answer is no. I will argue that the correct answer is yes. I present two novel arguments against grounding necessitarianism, and show that grounding (...) contingentism is fully compatible with the various explanatory roles that grounding is widely thought to play.

Discussion of the relevance of grounding to substantiveness, theory-choice, and “location problems” in metaphysics.

In his recent article entitled ‘Can We Believe the Error Theory?’ Bart Streumer argues that it is impossible (for anyone, anywhere) to believe the error theory. This might sound like a problem for the error theory, but Streumer argues that it is not. He argues that the un-believability of the error theory offers a way for error theorists to respond to several objections commonly made against the view. In this paper, we respond to Streumer’s arguments. In particular, in sections 2-4, (...) we offer several objections to Streumer’s argument for the claim that we cannot believe the error theory. In section 5, we argue that even if Streumer establishes that we cannot believe the error theory, this conclusion is not as helpful for error theorists as he takes it to be. (shrink)

Review the Istvan Kiraly V.'s book: Death and History.

Rational agents face choices, even when taking seriously the possibility of determinism. Rational agents also follow the advice of Causal Decision Theory (CDT). Although many take these claims to be well-motivated, there is growing pressure to reject one of them, as CDT seems to go badly wrong in some deterministic cases. We argue that deterministic cases do not undermine a counterfactual model of rational deliberation, which is characteristic of CDT. Rather, they force us to distinguish between counterfactuals that are relevant (...) and ones that are irrelevant for the purposes of deliberation. We incorporate this distinction into decision theory to develop ‘Selective Causal Decision Theory’, which delivers the correct recommendations in deterministic cases while respecting the key motivations behind CDT.

Miller has recently argued that the standard liberal and moderate positions on abortion are incapable of grounding the claim that ‘all non-disabled adult humans are equal’. The reason, he claims, is such accounts base the intrinsic moral worth of a human being on some property (or set of properties) which comes in degrees. In contrast, he argues that moral equality must reside in some binary property, such as the property of being human. In this paper, I offer three criticisms of (...) Miller’s position. (shrink)

The legal reasons that bind a judge and the moral reasons that bind all persons can sometimes pull in different directions. There is perhaps no starker example of such judicial dilemmas than in criminal sentencing. Particularly where mandatory minimum sentences are triggered, a judge can be forced to impose sentences that even the judge regards as “immensely cruel, if not barbaric.” Beyond those directly harmed by overly harsh laws, some courts have recognized that “judges who, forced to participate in such (...) inhumane acts, suffer a loss of dignity and humanity as well.” When faced with such a judicial dilemma—a powerful tension between the judge’s legal and moral reasons—the primary question is what a judge can do to resolve it. We argue that the two standard responses—sacrificing morality to respect the law (“legalism”), or sacrificing the law to respect morality (“moralism”)—are unsatisfying. Instead, this Article defends an underexplored third response: rather than abandoning one ideal to maximally promote the other, we argue that judges should seek to at least minimally satisfy the demands of both. Judges should, in other words, look for and employ what we dub Satisficing Options. These are actions that enjoy sufficient support from both the legal reasons and the moral reasons, and thus are both legally and morally permissible—even if the acts in question would not strictly count as optimal by the lights of the law or morality. This common sensical response to the problem is not only underappreciated in the literature, but also has great practical import. Focusing on the sentencing context, this Article demonstrates that judicial dilemmas can be systematically resolved, mitigated or avoided through a range of concrete strategies that on their own or in conjunction can constitute Satisficing Options: these strategies include seeking out legally permitted but morally preferable interpretations of the law, expressing condemnation of unjust laws in dicta, and seeking assistance or cooperation from other actors to help defendants facing substantively unjust mandatory sentences. While these strategies can at times also go too far, we argue that in certain contexts they can be sufficiently defensible on both legal and moral grounds to be a justifiable response to judicial dilemmas. This Article thus provides both a novel theoretical framework for understanding the justification of judicial responses to unjust laws, as well as a practical a menu of options which judges can use to guide their responses to the judicial dilemmas that they are increasingly likely to encounter within our criminal justice system.

This is the second part of a two-part series on the logic of hyperlogic, a formal system for regimenting metalogical claims in the object language (even within embedded environments). Part A provided a minimal logic for hyperlogic that is sound and complete over the class of all models. In this part, we extend these completeness results to stronger logics that are sound and complete over restricted classes of models. We also investigate the logic of hyperlogic when the language is enriched (...) with hyperintensional operators such as counterfactual conditionals and belief operators. (shrink)

A counterpossible is a counterfactual with an impossible antecedent. Counterpossibles present a puzzle for standard theories of counterfactuals, which predict that all counterpossibles are semantically vacuous. Moreover, counterpossibles play an important role in many debates within metaphysics and epistemology, including debates over grounding, causation, modality, mathematics, science, and even God. In this article, we will explore various positions on counterpossibles as well as their potential philosophical consequences.

ABSTRACT It has become standard to conceive of metalinguistic disagreement as motivated by a form of negotiation, aimed at reaching consensus because of the practical consequences of using a word with one content rather than another. This paper presents an alternative motive for expressing and pursuing metalinguistic disagreement. In using words with given criteria, we betray our location amongst social categories or groups. Because of this, metalinguistic disagreement can be used as a stage upon which to perform a social identity. (...) The ways in which metalinguistic disagreements motivated in this way diverge in character from metalinguistic negotiations are described, as are several consequences of the existence of metalinguistic disagreements motivated in this way.
