In this paper we will review the history of Quechua in the Peruvian territory (including the eras of the Inca empire, the viceroyalty, and the republic) and consider the challenges it faces in order to survive from the bicentenary of our republic onwards. I begin by showing that most varieties of Quechua are in a process of extinction and reflect on the causes that may have determined this trend in the republican era. I defend the thesis that it was the (...) progressive increase in opportunities for social mobility in the republic that motivated an increasing adoption of Spanish by Quechua speakers, since such opportunities depended on mastering Spanish. The paper closes by discussing about the possibilities to reverse the trend towards the extinction of Quechua. (shrink)

We present a bibliography of Francisco Miró Quesada Cantuarias’ works divided by subject and subdivided by work type, and compare it with the last version of that made by Sobrevilla.

This paper deals with a relatively recent trend in the history of analytic philosophy, philosophical logic, and theory of science: the philosophical study of the role of inconsistency in empirical science. This paper is divided in three sections that correspond to the three types of inconsistencies identified: (i) factual, occurring between theory and observations, (ii) external, occurring between two mutually contradictory theories, and (iii) internal, characterising theories that entail mutually contradictory statements.

In the course of this article we discussed the method of applying philosophy to adolescents, we count on the added experience during the year we worked in a technical college. We have chosen to apply a method that goes beyond the traditional, in order to make the philosophical act more natural and close to the students. We discuss the effectiveness of the traditional while showing the results achieved in this period. We worked with young people from fifteen to nineteen years, (...) these had their focus to learn the agricultural technical part, our challenge was to take philosophy to a group of students who had no real interest in the material, even thought it was useless. Thinking about the difficulties that it was to bring philosophical thought to these young people, together with the problems that are already part of the school, the different social contexts of the students, we developed classes and contents in order to work all these factors. We want to make these young people not simply knowledgeable of the concepts, but rather to broaden their worldview and logical thinking. (shrink)

Popper restricted his definition of falsifiability to consistent theories through what we may call his requirement of consistency. His main argument was that an inconsistent theory does not distinguish the sentences that corroborate it from those that contradict it, for all sentences follow from it. I propose to replace this requirement by the more basic requirement that the classes of potential corroborators and falsifiers of a theory do not overlap. This results not only in an unrestricted definition of falsifiability but (...) also in some inconsistent theories being falsifiable whenever that inconsistency is not located among its observational statements. Although this assumes a restriction of the principle of explosion or ex contradictione sequitur quodlibet (ECQ), it does not depend on any particular system or approach of paraconsistent logic. Finally, I propose to define the class of potential refuters of a theory, which is obtained by subtracting the class of potential corroborators from the class of potential falsifiers. Given that, by definition, the classes of potential refuters and corroborators of a theory do not overlap, it immediately follows that some observationally inconsistent theories are refutable in this sense. This establishes the bases for a new and more general formal theory of falsifiability of scientific factual/empirical theories. (shrink)

El documento expone los antecedentes sugeridos por Paul Ricoeur sobre lo que podría denominarse “la polémica epistemológica en ciencias sociales”, referidos a la formulación de un método legítimo para la investigación en dichas ciencias que responda a las particularidades propias de su objeto de estudio. En este sentido, se rastrea la cuestión en la tradición hermenéutica romántica, concretamente en el pensamiento de Wilhelm Dilthey, pasando por la teoría estructural de estudio del texto escrito y la formulación de una teoría de (...) la acción anglosajona, para finalmente terminar en la ricoeurtiana consideración hermenéutica de la acción significativa, que asume al texto como paradigma y propuesta de superación de los escollos en torno a la referida polémica.

In this paper I formalise the falsificationist proposal omitting Popper’s requirement of consistency. This omission results in (i) trivial theories being falsifiable in an inappropriate sense of the term, but also in (ii) some inconsistent non-trivial theories being so in an appropriate one. This justifies a slight alteration of the definition of falsifiability that excludes (i) but allows (ii). Instead of requiring that a falsifiable theory be consistent, my proposal only requires that the intersection of its classes of potential corroborators (...) and falsifiers be empty. (shrink)

The standard definition of “argument” is satisfied by any series of statements in which one (of the statements) is marked as the conclusion of the others. This leads to the counter-intuitive result that “I like cookies, therefore, all swans are white” is an argument, since “therefore” marks “all swans are white” as the conclusion of “I like cookies”. This objection is often disregarded by stating that, although the previous sequence is an argument, it fails to be a good one. However, (...) when we compare our previous argument with a definitely bad argument like “this swan is white, therefore, all swans are white”, we see that there is an important difference between them. Whereas the former fails to fulfil our intuition of what an argument is, the latter does qualify as an argument, but as a bad one. In this talk, I will sketch a definition that better captures this feature of our intuition of what an argument is in three steps. Following Díez and Moulines (1999), I first reduce inductive validity to deductive validity through what we may call the method of deductivisation. Second, through epistemic predicates (cf. Thompson 2002), I introduce a broader concept of validity that accounts not only for deductive and inductive validity, but also for a weaker type of validity that may be called pseudo-validity. I show that these pseudo-valid arguments can also be deductivised with the help of the above-mentioned epistemic predicates. Finally, I re-define the concept of argument as any series of statements that is at least pseudo-valid, which leaves the “cookies argument” outside of this definition. (shrink)

According to falsificationism, a theory is scientific if it can be incompatible with some empirically testable statements. This epistemological approach has been criticized because, in practice, it is impossible to decide when a particular fact should be considered incompatible with a theory. These criticisms, however, neglect the fact that the Popperian sense of falsification is a “logical sense.” Thus, the Popperian criterion of falsifiability only requires that, assuming certain auxiliary hypotheses, the theory in question be logically incompatible with some empirically (...) testable statements. This paper presents a reassessment of these criticisms, justifying that the criterion of falsifiability is unrenounceable insofar as our best theories should aspire to satisfy it. (shrink)

In this paper, I study the relation between arguments against the person (aka ad hominem or personal attack arguments) and disqualifications for conflicts of interests. I show that both types of arguments share a similar logical structure and that they can be considered to be acceptable in similar circumstances.

This paper discusses the logical possibility of testing inconsistent empirical theories. The main challenge for answering this affirmatively is to avoid that the inconsistent consequences of a theory both corroborate it and falsify it. I answer affirmatively by showing that we can define a class of empirical sentences whose truth would force us to abandon such inconsistent theory: the class of its potential rejecters. Despite this, I show that the observational contradictions implied by a theory could only be verified (provided (...) we make some assumptions), but not rejected. From this, it follows that, although inconsistent theories are rejectable, they cannot be rejected qua inconsistent. (shrink)

From the apparently trivial problem of homonyms, I argue that proper names as they occur in natural languages cannot be characterised as strings of sounds or characters. This entails, first, that the proper names philosophers talk about are not physical entities, like strings, but abstractions that, second, may be better characterised as triples (s, m, C), where s is the string that conveys the meaning m in a set of contexts C. Third, the generality principle of compositionality may be put (...) into question, for apparently its converse holds in some cases. Finally, the prominence of context for determining the meaning expressed by a sign suggests a strong connection between proper names and indexicals. This connection has been largely overlooked by the analytic tradition, in spite that both proper names and indexicals have been among their hottest topics. This may be because the analytic literature about proper names has been decisively influenced by Frege’s work, which was better suited for formal languages. Izydora Dąmbska and Jerzy Pelc, with their semiotic background, were able to have a finer understanding of this quasi-indexical character of proper names. (shrink)

This is the story of how the noble squire Sancho Panza, while governing what he thought to be an insula, ingeniously solved a paradox not unlike those of modern logic.

The possibility of testing contradictory statements about the factual world has been suggested but barely discussed in the relevant literature. Here I argue that if we assume that there are contradictory observation sentences, it would be logically impossible to falsify them. Accordingly, the extension of the dialetheist programme into empirical science would be non-advisable, for it would introduce logically unfalsifiable claims.

In this paper, I generalise the logical concept of compatibility into a broader set-theoretical one. The basic idea is that two sets are incompatible if they produce at least one pair of opposite objects under some operation. I formalise opposition as an operation ′ ∶ E → E, where E is the set of opposable elements of our universe U, and I propose some models. From this, I define a relation ℘U × ℘U × ℘U^℘U, which has (mutual) logical compatibility (...) as its more natural interpretation. (shrink)

Comments on the paper: Pluralismo y absolutismo en la crítica. Dialéctica reflexiva y política democrática a partir de M. Horkheimer y Th. W. Adorno, by Emiliano Matías Gambarotta.

This dissertation offers a proof of the logical possibility of testing empirical/factual theories that are inconsistent, but non-trivial. In particular, I discuss whether or not such theories can satisfy Popper's principle of falsifiablility. An inconsistent theory Ƭ closed under a classical consequence relation implies every statement of its language because in classical logic the inconsistency and triviality are coextensive. A theory Ƭ is consistent iff there is not a α such that Ƭ ⊢ α ∧ ¬α, otherwise it is inconsistent. (...) We say, instead, that Ƭ is non-trivial iff there is at least one α such that Ƭ ⊢ α, otherwise we say that it trivial. This happens because classical logic satisfies the principle of explosion, according ex contradictione sequitur quodlibet (from a contradiction anything follows). Under these conditions inconsistent classical theories would be compatible with any well-formed formula, which makes them useless for science. There are, however, so-called paraconsistent logics in which the principle of explosion does not generally hold and in which a theory can be (simply) inconsistent, but also absolutely consistent. It is in this logical framework that we can prove that some inconsistent theories can be falsifiable. (shrink)

A non-embracing consequence relation is one such that no set of wffs closed under it is equal to the set of all wffs. I prove that these relations have no deductive power if they are also extensive and monotonic.

Logic systems that can handle contradictions were being used for some time without having a general technical name. One of the main proposers of these systems, Newton da Costa, asked Francisco Miró Quesada to suggest him a name for those systems. In the historical letter that here we translate into English for the first time, Miró Quesada suggests three names to da Costa for this purpose: ‘ultraconsistent’, ‘metaconsistent’, and ‘paraconsistent’; explaining their pros and cons. -/- Paper based on a letter (...) by Francisco Miró Quesada Cantuarias to Newton da Costa, edited, translated, and annotated by Luis Felipe Bartolo Alegre.

In this historical article, Newton da Costa discusses Francisco Miró Quesada’s philosophical ideas about logic. He discusses the topics of reason, logic, and action in Miró Quesada’s work, and in the final section he offers his critical view. In particular, he disagrees with Miró Quesada’s stance on the historicity of reason, for whom “reason is essentially absolute”, whereas for da Costa it “is being constructed in the course of history”. Da Costa concludes by emphasizing the importance of Miró Quesada’s theory (...) of logic and reason, despite it still being incomplete. -/- Historical article by Newton da Costa, annotated and translated by J.

Relativamente difundida na teoria democrática contemporânea, a dicotomia entre democracia epistêmica e democracia agonística é endossada por autores como Luis Felipe Miguel, Chantal Mouffe e Nadia Urbinati. De acordo com eles, a ideia de que a deliberação democrática possa funcionar como uma troca de argumentos racionais que visa à verdade é incompatível com o reconhecimento do conflito como um componente basilar da política. Tudo se passa, pois, como se a abordagem epistêmica estivesse fadada a obliterar a dimensão agonística (...) da política. A fim de problematizar semelhante entendimento, este artigo reconstrói a associação entre democracia e compromisso feita por John Stuart Mill, John Morley e Hans Kelsen e conclui que a conceitualização da democracia como compromisso oferece uma alternativa à dicotomia democracia epistêmica vs. democracia agonística.

RESUMO A Transferência de Embrião (TE) em bovinos se trata de uma técnica mundialmente disseminada com objetivo de aumentar a capacidade reprodutiva da fêmea. Mantém vínculo direto com outras técnicas das biotecnologias da reprodução, como, a Ovum Pick-Up (OPU), Produção In Vitro e In Vivo de embriões (PIVE) e Transferência de Embrião em Tempo Fixo (TETF), sendo estas, técnicas que fazem parte de um processo, que vai desde a seleção de doadoras, passando pelo preparo dos embriões até sua inovulação em (...) receptoras criteriosamente selecionadas. Com seu avanço, várias tecnologias de manejo vêm sendo implantadas: formas no transporte de embriões, protocolos de sincronização de doadoras e receptoras, e protocolos de recuperação de oócitos para produção de embriões. Isto infundiu a tecnologia, porém, os investimentos previstos para a produção de um animal de alto mérito genético limita sua utilização. Contudo, esta análise abordou avanços tecnológicos essenciais para o sucesso da TE, incluindo novos protocolos, sexagem de embriões, além do uso de embriões congelados Direct Transfer (DT) e vitrificados. No entanto, é claro que o sucesso do procedimento está no processo como um todo, em destaque ressalta-se que é de grande valia que o profissional apto a executar a técnica esteja sempre preparado e atualizado garantindo qualidade, eficiência e sustentabilidade na pecuária. Esta revisão foi desenvolvida com o propósito de adquirir conhecimento teórico, de forma detalhada e crítica, nas técnicas e procedimentos de Transferência de Embriões em bovinos, incluindo a colheita, manipulação e implantação de embriões. Palavras-chaves: Bovino, doadora, embrião, receptora. ABSTRACT Embryo Transfer (ET) in cattle is a globally widespread technique aimed at enhancing the reproductive capacity of females. It is closely linked to other techniques in reproductive biotechnologies, such as Ovum Pick-Up (OPU), In Vitro and In Vivo Embryo Production (PIVE), and Timed Embryo Transfer (TET), all of which are part of a process that ranges from donor selection, through embryo preparation, to their inoculation into carefully chosen recipients. With its advancement, various management technologies have been implemented: including methods for embryo transport, synchronization protocols for donors and recipients, and oocyte recovery protocols for embryo production. Although technology has been infused, the anticipated investments for producing animals of high genetic merit limit its widespread use. However, this analysis addressed essential technological advances for the success of ET, including new protocols, embryo sexing, as well as the use of frozen-thawed (DT) and vitrified embryos. Nevertheless, it is clear that the success of the procedure lies in the entire process. Notably, it emphasizes the significant value of having a qualified professional who is always prepared and updated to ensure quality, efficiency, and sustainability in livestock farming. This literary review was developed with the purpose of acquiring theoretical knowledge, in a detailed and critical way, on the techniques and procedures of Embryo Transfer in cattle, including the collection, manipulation and implantation of embryos.

Aristotle’s dialogue Protrepticus is not only his earliest work of ethics but also the root of all his subsequent investigations into ethics. Here we explore the various ways Aristotle retained in memory the contents of the Protrepticus and redeployed them in the Eudemian Ethics, including the common books. Since Aristotle himself does not explicitly acknowledge the foundational significance of the Protrepticus to his later works, our exploration must proceed on the basis of our knowledge of the earlier work, which can (...) then related to comparable passages in the treatises. But the Protrepticus is a lost work, unlike the EE and the EN, in the sense that no medieval manuscripts of it have survived. And so it first needs to be reconstructed on the basis of the streams of reception that deposited information in surviving works by later ancient authors. We begin in part 1 by reviewing the surviving evidence of the Protrepticus before presenting our wider reconstruction and conception of the work as a dialogue in part 2. In part 3, we discuss ideas and arguments in the reconstructed dialogue that are retained and redeployed in the Eudemian Ethics, focussing on the account of intellectual virtues in EE v and the introduction and methodological framework in EE i-ii.1.

Aristotle's General Definition of the Syllogism may be taken as consisting of two parts: the Inferential Conditions and the Final Clause. Although this distinction is well known, traditional interpretations neglect the Final Clause and its influence on syllogistic. Instead, the aforementioned tradition focuses on the Inferential Conditions only. We intend to show that this neglect has severe consequences not just on syllogistic but on the whole exegesis of Aristotle's Prior Analytics I. Due to these consequences, our objective is to analyse (...) the General Definition's Final Clause and its consequences on syllogistic. We propose a reading of the Final Clause as an additional criterion for distinguishing some arguments as properly syllogistic ones and as a main theme which connects all parts of the Prior Analytics I into one coherent piece of work.

Two arguments in Eudemian Ethics 2 that are crucial to Aristotle’s definition of moral virtue as a mean state contain claims that Aristotle says are clear by induction. In these contexts, he explicitly appeals to examples coming from arts and sciences like gymnastic training and medicine for evidence. But Aristotle does not here, or elsewhere (at least in any extant work), including the parallel arguments in the Nicomachean Ethics, actually supply or discuss the evidence that makes these inductive arguments clear. (...) Fortunately, strong support for them can be found in the Hippocratic Corpus, especially in On Ancient Medicine and On Regimen. (shrink)

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My (...) analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science. (shrink)

It’s constitutive of classical theism that there is a necessarily existent personal god who is also the creator of the universe, where the latter claim includes at least the following three theses: (i) God is wholly distinct from the natural world; (ii) God is the originating or sustaining cause of the natural world; and (iii) God created the natural world ex nihilo, i.e., without the use of pre-existing materials. Call this tripartite component of classical theism the classical view of creation. (...) In this paper, I offer a new argument against classical theism. In particular, I argue that creation ex nihilo is prima facie impossible, and that since the doctrine of creation ex nihilo is constitutive of classical theism, classical theism is false. (shrink)

This collection highlights the new trend away from rationalism and toward empiricism in the epistemology of modality. Accordingly, the book represents a wide range of positions on the empirical sources of modal knowledge. Readers will find an introduction that surveys the field and provides a brief overview of the work, which progresses from empirically-sensitive rationalist accounts to fully empiricist accounts of modal knowledge. Early chapters focus on challenges to rationalist theories, essence-based approaches to modal knowledge, and the prospects for naturalizing (...) modal epistemology. The middle chapters present positive accounts that reject rationalism, but which stop short of advocating exclusive appeal to empirical sources of modal knowledge. The final chapters mark a transition toward exclusive reliance on empirical sources of modal knowledge. They explore ways of making similarity-based, analogical, inductive, and abductive arguments for modal claims based on empirical information. Modal epistemology is coming into its own as a field, and this book has the potential to anchor a new research agenda. (shrink)

Aristotle rejected the idea of a single, overarching super-science or “theory of everything”, and he presented a powerful and influential critique of scientific unity. In theory, each science observes the facts unique to its domain, and explains these by means of its own proper principles. But even as he elaborates his prohibition on kind-crossing explanations (Posterior Analytics 1.6-13), Aristotle points out that there are important exceptions—that some sciences are “under” others in that they depend for their explanations on the principles (...) of a superior (more architectonic) science. In this paper, I explore how subordination relations and architectonic structures apply to Aristotle’s scientific practice—including not only the works of theoretical philosophy, which have already been discussed in this connection, but also in and between these and the practical and productive sciences.

El objetivo de este estudio es contribuir a esta transformación en los procesos de aprendizaje para avanzar en el dominio del inglés, con un diseño didáctico innovador inspirado en el concepto de ‘entorno personal de aprendizaje’, con el uso de vídeos de YouTube. Los resultados demuestran el potencial pedagógico de los PLE, su eficacia no sólo a nivel cognitivo sino también como experiencia emocional. Este (...) diseño también se ha mostrado de utilidad para promover la autonomía y la motivación intrínseca del estudiante. (shrink)

I argue that a circa first century B.C./A.D. anonymous epistolary comic novel depicting a fictional interaction between Hippocrates of Cos and Democritus of Abdera contains an insightful imitation of Democritus that can cast light on the historical Democritus’s thought, including his thought on the touchy subject of appropriate and inappropriate laughter. The only thing certain about Democritus’s view of laughter is that he denounced laughter at human misfortune as inappropriate. The later legend of him as laughing at everything and everyone (...) indiscriminately is a later distortion of his view which the author of the comic novel seems concerned to counteract. (shrink)

Besides the general agreement about the human capability of reflection, there is a large area of disagreement and debate about the nature and value of “reflective scrutiny” and the role of “second-order states” in everyday life. This problem has been discussed in a vast and heterogeneous literature about topics such as epistemic injustice, epistemic norms, agency, understanding, meta-cognition etc. However, there is not yet any extensive and interdisciplinary work, specifically focused on the topic of the epistemic value of reflection. This (...) volume is one of the first attempts aimed at providing an innovative contribution, an exchange between philosophy, epistemology and psychology about the place and value of reflection in everyday life. -/- Our goal in the next sections is not to offer an exhaustive overview of recent work on epistemic reflection, nor to mimic all of the contributions made by the chapters in this volume. We will try to highlight some topics that have motivated a new resumption of this field and, with that, drawing on chapters from this volume where relevant. -/- Two elements defined the scope and content of this volume, on the one hand, the crucial contribution of Ernest Sosa, whose works provide original and thought-provoking contributions to contemporary epistemology in setting a new direction for old dilemmas about the nature and value of knowledge, giving a central place to reflection. On the other hand, the recent developments of cultural psychology, in the version of the “Aalborg approach”, reconsider the object and scope of psychological sciences, stressing that “[h]uman conduct is purposeful”.

Pierre Gassendi was a major factor in the revival of Epicureanism in early modern philosophy, not only through his contribution to the restoration and criticism of Epicurean texts, but also by his adaptation of Epicurean ideas in his own philosophy, which was itself influential on such important figures of early modern philosophy as Hobbes, Locke, Newton, and Boyle (to name just a few). Despite his vigorous defense of certain Epicurean ideas and ancient atomism, Gassendi goes to great lengths to differentiate (...) his philosophy from Epicureanism on certain key points. In this paper I argue that those key points on which Gassendi rejects and and criticizes the Epicurean view, such as the immortality of the soul and divine creation of the cosmos, are central not only to Epicureanism, but also to Gassendi's own philosophy. In order to see Gassendi's philosophy for what it is, and understand its role in the history of natural theology, we need accept and understand better why he rejected the central theses of Epicureanism.

Neste trabalho, investigo a possibilidade de compatibilidade entre o pessimismo filosófico e a compreensão da morte como um mal para quem morre. Por pessimismo filosófico, compreendo a doutrina filosófica que mantém como tese fundamental que a não-existência é preferível à existência, de modo que o pessimismo é tomado como a filosofia de que a vida não vale a pena ser vivida. Por mal da morte, me refiro à compreensão da morte como um dano para o indivíduo que morre, cujo pressuposto (...) em diferentes abordagens contemporâneas é o de que a morte só é um mal no caso de continuar existindo ser preferível a deixar de existir. Desse modo, o problema discutido é a aparente incompatibilidade entre a tese de que a não-existência é preferível à existência e a tese de que continuar existindo é preferível a deixar de existir. Busco demonstrar que essa (in)compatibilidade depende do modo como fundamentamos o pessimismo filosófico. Para tanto, examino dois argumentos para o pessimismo filosófico e suas implicações para o mal da morte: o argumento a priori de Arthur Schopenhauer e o argumento da assimetria de David Benatar. Concluo que o primeiro desses argumentos nos leva para a conclusão de que a morte não é um mal, mas que o segundo argumento compatibiliza o pessimismo filosófico e a compreensão da morte como um mal para quem morre.

We offer a sceptical examination of a thesis recently advanced in a monograph published by Princeton University Press, entitled Greek Buddha: Pyrrho’s Encounter with Early Buddhism in Central Asia. In this dense and probing work, Christopher I. Beckwith, a professor of Central Eurasian studies at Indiana University, Bloomington, argues that Pyrrho of Elis adopted a form of early Buddhism during his years in Bactria and Gandhāra, and that early Pyrrhonism must be understood as a sect of early Buddhism. In making (...) his case Beckwith claims that virtually all scholars of Greek, Indian, and Chinese philosophy have been operating under flawed assumptions and with flawed methodologies, and so have failed to notice obvious and undeniable correspondences between the philosophical views of the Buddha and of Pyrrho. In this study we take Beckwith’s proposal and challenge seriously, and we examine his textual basis and techniques of translation, his methods of examining passages, his construal of problems and his reconstruction of arguments. We find that his presuppositions are contentious and doubtful, his own methods are extremely flawed, and that he draws unreasonable conclusions. Although the result of our study is almost entirely negative, we think it illustrates some important general points about the methodology of comparative philosophy. (shrink)

The potential reducibility of chemical entities to their physical bases is a matter of dispute between ontological reductionists on one hand, and emergentists on the other. However, relevant debates typically revolve around the reducibility of so-called ‘higher-level’ chemical entities, such as molecules. Perhaps surprisingly, even committed proponents of emergence for these higher-level chemical entities appear to accept that the ‘lowest-level’ chemical entities – atomic species – are reducible to their physical bases. In particular, the microstructural view of chemical elements, actively (...) developed and defended by emergentists, appears to hold that the explanatory power of nuclear charge justifies being reductionist about atomic species. My first task in this paper is to establish that nuclear charge cannot ultimately provide explanations sufficient to justify a reductionist approach to atomic species, unless we abandon the persuasive intuition that the presence of an element in a substance ought to explain the properties of that substance. The ‘missing piece’ for explaining the properties of substances by way of their elemental constituents is the electronegativity values of participant atoms. But electronegativity is a strikingly disunified concept that appears distinctly unamenable to analysis by way of fundamental physical principles. Through evaluating the uncertain physical identity of electronegativity, as well as its widespread and indispensable epistemic utility in chemical practice, I argue that electronegativity provides compelling grounds to seriously consider emergence for atomic species.

The thought experiment is a seemingly indispensable tool in the armchair philosopher’s toolbox. One wonders, for example, how philosophers could come to think that justified true belief isn’t knowledge, that reference isn’t determined by an expression’s associated description, or that moral responsibility doesn’t require the ability to do otherwise, without the use of thought experiments. But even if thought experiments play an integral role in philosophical methodology, their legitimacy is at least initially puzzling: one would think that significant knowledge of (...) the world requires extensive empirical investigation. But since thought experiments are done from the armchair, how can they tell us about the world? -/- A standard account of the nature and utility of thought experiments provides an answer to this question, and in a way that fits naturally with a standard picture of the nature of the facts philosophers investigate: Philosophers are about the business of investigating the essences of things and kinds. But a thing’s essential and accidental properties are modal properties. Thus, one can discern a thing’s essence by discovering its modal profile. But if so, then thought experiments are naturally suited as tools for the armchair philosopher. For thought experiments shed light on modal facts. Therefore, since philosophers investigate essences, facts about essence are modal facts, and the thought experiment is one of the few tools they have for discerning such facts, thought experiments play a legitimate and indispensable role in philosophical methodology. In my dissertation, I argue that the standard account of the nature and utility of thought experiments is inadequate, and sketch a more promising account. -/- First, I argue that our knowledge of possibility is restricted to the relatively humdrum. And if so, then since the standard account ties the utility of thought experiments to our knowledge of possibility, too many thought experiments will be ruled out as useless, which raises serious concerns about the significance, and perhaps even the legitimacy, of armchair philosophy. Thus, there is pressure for armchair philosophers to reject the standard account. -/- Second, I sketch an alternative picture of the nature of facts philosophers investigate – one that’s more fine-grained than the standard modal-profile picture. Relatedly, I sketch a correspondingly fine-grained semantics for claims about such facts. This alternative picture underwrites the legitimacy of a hitherto underappreciated sort of thought experiment, which I call the non-modal thought experiment. Such thought experiments shed light on facts about the world that are more fine-grained than what can be discerned by merely examining their modal profiles. I argue that non-modal thought experiments often succeed at just the points where the more familiar modal thought experiments fail, and thus that the two are naturally suited to complement one another in the philosopher’s practice. -/- Finally, I exploit the points mentioned above to sketch an account of the variety and utility of thought experiments that’s much more nuanced than that of the standard account. I then illustrate some of its virtues by indicating its ability to account for a wide range of epistemically forceful thought experiments – both humdrum and exotic –, and by demonstrating how it can be used to make progress in debates that have reached a stalemate due to conflicting modal intuitions. -/- .

Critics have alleged that Democritus’ ethical prescriptions (“gnomai”) are incompatible with his physics, since his atomism seems committed to necessity or chance (or an awkward combination of both) as a universal cause of everything, leaving no room for personal responsibility. I argue that Democritus’ critics, both ancient and contemporary, have misunderstood a fundamental concept of his causality: a cause called “spontaneity”, which Democritus evidently considered a necessary (not chance) cause, compatible with human freedom, of both atomic motion and human actions. (...) Some influential contemporary compatibilists have argued that freedom and responsibility are compatible with causal determinism, but not intentional constraint where some other agent is intentionally manipulating or coercing one’s actions. In line with this, Democritus holds that humans should not blame their actions on other agents like the gods, or agent-like external forces like fate or chance, but should assume ultimate intentional control over their own choices and actions. The famous remark of his associate Leucippus that “everything happens for a reason and out of necessity” is a fitting slogan of their atomistic philosophy, for Democritus pursued what can without anachronism be recognized as a causal theory of freedom.

The philosophy of perception has been mostly focused on vision, to the detriment of other modalities like audition or olfaction. In this paper I focus on olfaction and olfactory experience, and raise the following questions: is olfaction a perceptual-representational modality? If so, what does it represent? My goal in the paper is, firstly, to provide an affirmative answer to the first question, and secondly, to argue that olfaction represents odors in the form of olfactory objects, to which olfactory qualities are (...) attributed. In order to do this I develop an empirically adequate notion of olfactory object that is sensitive to the peculiarities of olfaction, and defend it against various objections. (shrink)

I develop a positive interpretation of Democritus' theory of agency and responsibility, building on previous studies that have already gone far in demonstrating his innovativeness and importance to the history and philosophy of these concepts. The interpretation will be defended by a synthesis of several familiar ethical fragments and maxims presented in the framework of an ancient problem that, unlike the problem of free will and determinism, Democritus almost certainly did confront: the problem of the causes of human goodness and (...) success. I will argue that Democritus' account of the virtues and success is naturally interpreted as an intellectualist one. His focus on our intellectual powers as the source of our own agency and cause of our success led him to remarkable breakthroughs in moral psychology, including the development of a kind of cognitive-behavioral therapy for stress and anxiety, and the proposal of an autonomous source of moral sanction.

In some influential histories of ancient philosophy, teleological explanation and mechanistic explanation are assumed to be directly opposed and mutually exclusive alternatives. I contend that this assumption is deeply flawed, and distorts our understanding both of teleological and mechanistic explanation, and of the history of mechanistic philosophy. To prove this point, I shall provide an overview of the first systematic treatise on mechanics, the short and neglected work Mechanical Problems, written either by Aristotle or by a very early member of (...) his school. I will argue that the work is thoroughly Aristotelian in methodology, and that taking it seriously can deepen our understanding of Aristotle’s discussion of animal and human self-motion in the Physics and On the Movement of Animals.

While most people believe the best possible life they could lead would be an immortal one, so‐called “immortality curmudgeons” disagree. Following Bernard Williams, they argue that, at best, we have no prudential reason to live an immortal life, and at worst, an immortal life would necessarily be bad for creatures like us. In this article, we examine Bernard Williams' seminal argument against the desirability of immortality and the subsequent literature it spawned. We first reconstruct and motivate Williams' somewhat cryptic argument (...) in three parts. After that, we elucidate and motivate the three best (and most influential) counterarguments to Williams' seminal argument. Finally, we review, and critically examine, two further distinct arguments in favor of the anti‐immortality position. (shrink)

A key premise of the kalam cosmological argument is that the universe began to exist. However, while a number of philosophers have offered powerful criticisms of William Lane Craig’s defense of the premise, J.P. Moreland has also offered a number of unique arguments in support of it, and to date, little attention has been paid to these in the literature. In this paper, I attempt to go some way toward redressing this matter. In particular, I shall argue that Moreland’s philosophical (...) arguments against the possibility of traversing a beginningless past are unsuccessful. (shrink)

Desde os tempos mais remotos, busca-se por equilíbrio entre o delito e a punição. Este artigo estabelece uma relação entre o conceito de Justiça em Aristóteles e a proporcionalidade em matéria penal. Para melhor compreensão do tema, inicia-se o estudo pelos principais pontos da obra Ética a Nicômaco, especialmente o Livro V, que trata da Justiça. A partir de então, aborda-se o princípio da proporcionalidade e a forma pela qual os conceitos de Aristóteles influenciaram a concepção desse princípio. Ato contínuo, (...) investiga-se a realidade atual do sistema carcerário, sendo avaliadas as estatísticas produzidas pelos órgãos competentes. Por conseguinte, enfatiza-se o Estado de Coisas Inconstitucional para verificar a questão penitenciária à luz da decisão da Suprema Corte brasileira na ADPF n. 347/DF. Ao final, pondera-se acerca da forma pela qual se pune no Brasil para investigar se suas premissas respeitam ou não as balizas do conceito de Justiça aristotélico e o princípio da proporcionalidade. Para o desenvolvimento desta pesquisa, utilizou-se o método qualitativo, por meio da leitura de obras que obedecem ao eixo temático exposto nos objetivos e que permitem o fichamento do repertório selecionado. Além de ter sido analisada juriprudência, foram coletados dados do censo penitenciário. Finalmente, articulou-se o material consultado com as estatísticas do sistema prisional. Concluiu-se nesta pesquisa que o Poder Executivo é omisso e ineficiente para garantir os direitos dos encarcerados, não obstante todo o avanço normativo sobre o tema. Como se não bastasse, na prática forense brasileira a proporcionalidade não é mais que mera previsão abstrata. (shrink)
