Este artículo se propone mostrar, en contra de las interpretaciones dominantes, que Platón debió tempranamente postular la supervivencia del alma como un sujeto independiente de daño y beneficio moral con el objeto de completar su defensa de la ética socrática – en particular el principio de Soberanía de la Virtud, central en diálogos tempranos como la Apología, el Critón y el Gorgias. Al dualismo metafísico que resulta de este postulado le denomino ‘dualismo socrático’, para diferenciarlo del dualismo maduro expuesto por (...) Platón en el Fedón. (shrink)

In this paper we develop Aristotle’s remarks about personal enmity into a systematic account, with a view to determining whether personal enmity has a role to play in the good life. We argue that such an account can be obtained by examining Aristotle’s claims about hatred, and that this examination reveals that there is a significant place for enmity in Aristotle’s conception of the good life.

El propósito de este artículo es ofrecer una reconstrucción de la teoría ética presentada porCalicles en el Gorgias de Platón, con el apoyo de otros textos de la época que contribuyen a explicardicha teoría y a refinarla. El primer paso de esta reconstrucción es mostrar que Calicles ofrece unateoría perspectivista de los juicios morales, de acuerdo a la cual los juicios morales pueden emitirsedesde dos perspectivas radicalmente distintas – la perspectiva contractual, y la natural. El segundo esmostrar que Calicles emplea (...) un peculiar concepto de naturaleza que le permite sostener que ciertosderechos y prerrogativas naturales provenientes de una perspectiva natural, han de imperar por sobrelos que se derivan de la perspectiva contractual. El resultado es una teoría que además de tener un altovalor filosófico, parece no ser vulnerable a varias de las dificultades fundamentales señaladas por lasinterpretaciones dominantes, ni estar tampoco afecta al implausible hedonismo burdo que Platón leatribuye a Calicles en el diálogo.

In Chapter 3 of Judgment and Agency, Ernest Sosa (2015) explicates the concept of a fully apt performance. In the course of doing so, he draws from illustrative examples of practical performances and applies lessons drawn to the case of cognitive performances, and in particular, to the cog- nitive performance of judging. Sosa's examples in the practical sphere are rich and instructive. But there is, I will argue, an interesting disanalogy between the practical and cognitive examples he relies (...) on. Ultimately, I think the source of the disanalogy is a problematic picture of the cogni- tive performance of guessing and its connection to knowledge and defeat. Once this critical line of argument is advanced, an alternative picture of guessing, qua cognitive performance, is articulated, one which avoids the problems discussed, and yet remains compatible with Sosa's broader framework.

In a series of works Ernest Sosa (see Sosa 1991, 2007, 2009, 2010, 2011, 2015, 2017) has defended the view that there are two kinds or ‘grades’ of knowledge, animal and reflective. One of the most persistent critics of Sosa’s attempts to bifurcate knowledge is Hilary Kornblith (see Kornblith 2004, 2009, 2012). Our aim in this paper is to outline and evaluate Kornblith’s criticisms. We will argue that, while they raise a range of difficult (exegetical and substantive) (...) questions about Sosa’s ‘bi-level’ epistemology, Sosa has the resources to adequately respond to all of them. Thus, this paper is a (qualified) defence of Sosa’s bi-level epistemology. (shrink)

I give an exposition and critical discussion of Sellars’s Myth of the Given, and especially of its epistemic side. In later writings Sellars takes a pragmatist turn in his epistemology. This is explored and compared with his earlier critique of givenist mythology. In response to Michael Williams, it is argued that these issues are importantly independent of philosophy of language or mind, and that my own take on them does not commit me to any absurd radical foundationalism on language or (...) mind. My own take is in line with Descartes’ two-level epistemology of cognitio and scientia, a bifurcation that protects him from vicious circularity, and is adaptable for an epistemology naturalized, whether in the way of Quine, or Moore, or Davidson.

A kind of intellectual project characteristic of Ernest Sosa is to resolve an apparently flat-out dispute by showing that it is not after all a zero-sum game. His irenic goal is to do justice to both sides and give each of them most of what it wants. In his subtle paper ‘Abilities, Concepts, and Externalism’ he applies this strategy to the dispute between internalism and externalism in the philosophy of mind. It is a pleasure to engage in discussion with (...) a philosopher of Sosa’s fair-mindedness and analytical skills. (shrink)

Ernest Sosa has recently argued that the knowledge we get from instruments and the knowledge we get from testimony is similar in important ways. Most importantly, the justification that supports it is similar in kind – both instrumental justification and justification from testimony is to be understood in terms of reliability. I argue that Sosa’s theory is problematic. Specifically, I argue that we can take certain attitudes towards people that we cannot coherently take towards instruments. This, I argue, (...) grounds a distinction between the kind of justification that testimony can make available and the kind of justification that instruments can make available. The result is that reliability cannot provide a complete explanation of the justification that testimony makes available. (shrink)

Ernest Sosa draws a distinction between animal knowledge and reflective knowledge, and this distinction forms the centerpiece of his new book, A Virtue Epistemology . This paper argues that the distinction cannot do the work which Sosa assigns to it.

Aware that the representational thesis is more plausible for the attitudinal than for the phenomenal, Dretske courageously focuses on sensory experience, where progress in our philosophical understanding of the mental has lagged. His view, essentially, is that what makes any mental state what it is is not so much what it's like as what it's about.

In my remarks, I discuss Sosa's attempt to deal with the sceptical threat posed by dreaming. Sosa explores two replies to the problem of dreaming scepticism. First, he argues that, on the imagination model of dreaming, dreaming does not threaten the safety of our beliefs. Second, he argues that knowledge does not require safety, but a weaker condition which is not threatened by dreaming skepticism. I raise questions about both elements of his reply.

This paper offers and analysis of Ernest Sosa's Virtue Perspectivism. Although Sosa has been credited with fathering the influential contemporary movement known as Virtue Epistemology, I argue that Sosa imprudently abandons the reliabilist-based insights of Virtue Epistemology in favor of a reflection-based, "perspectival"' view. Sosa's mixed allegiance to reliabilist-based and reflection-based views of knowledge, in fact, leads to an unwelcome tension in his thought which can be relieved by recognizing that his reflection-based view is in fact (...) an account of the cognitive state of understanding, rather than an account of knowledge. Sosa makes matters difficult for himself because he expects too much, as it were, from the concept of knowledge, and in the process burdens his view with elements of reflection it does not require. To solve the problem, I suggest that Sosa needs to develop a two-tiered epistemology which recognizes that knowledge, on the one hand, and understanding, on the other, both have necessary and sufficient conditions unique to themselves.

Relocating Kripke's puzzle about belief, this paper investigates i) in what the puzzle consists, exactly; ii) the method used in its construction; and iii) relations between meaning and rationality. Essential to Kripke's puzzle is a normative notion of contradictory belief. Different positions about the meaning of names yield different views of what constitutes the attribution of contradictory belief; and Kripke's puzzle unwittingly _imports a Millian assumption. Accordingly, the puzzle about belief is not independent of positions about the meaning of names.

Sosa takes epistemic normativity to be kind of performance normativity: a belief is correct because a believer sets a positive value to truth as an aim and performs aptly and adroitly. I object to this teleological picture that beliefs are not performances, and that epistemic reasons or beliefs cannot be balanced against practical reasons. Although the picture fits the nature of inquiry, it does not fit the normative nature of believing, which has to be conceived along distinct lines.

This is the first book devoted to the work of Ernest Sosa, one of the most influential contemporary epistemologists. Part of the acclaimed Philosophers and Their Critics series. The editor’s introduction serves as an introduction to Sosa’s epistemology. Contains critical essays by more than twenty of the most prominent epistemologists in the world, commenting on Sosa's work. Concludes with Sosa’s own reply to his critics.

Ernest Sosa argues for two levels of knowledge, the animal and the reflective, each viewed as a distinctive human accomplishment.

Fortunately for those of us who work on the topic, Ernie Sosa has devoted much of his (seemingly inexhaustible) intellectual energy to the problem of philosophical skepticism. And to great effect. With the three exceptions of Peter Unger, whose 1975 Ignorance: A Case for Scepticism is a grossly under-appreciated classic of epistemology; Timothy Williamson, whose 2000 Knowledge and its Limits is, I hope, on its way to being a less underappreciated classic; and Thomas Reid, I have benefitted more from (...) Sosa’s wrestlings with skepticism than from anyone else’s work on the topic. (shrink)

This paper takes issues with a couple of recent arguments due to Ernest Sosa according to which knowledge is the norm of assertion and the thesis that knowledge is specially valuable is equivalent to the thesis that knowledge is the norm of assertion. It is argued that while both of these arguments fail, an argument that knowledge is the norm of belief and that the thesis that knowledge is specially valuable is equivalent to the thesis that knowledge is the (...) norm of belief may yet be defensible.

This paper is a critical discussion of Ernest Sosa’s recent analysis of reflective knowledge.

Alvin Plantinga has proposed a fascinating epistemology, one which he considers to be completely naturalized. Critical to his epistemology is the notion of a 'design plan' which circumscribes the function of organs or systems. Ernest Sosa has objected to Plantinga by using Donald Davidson's Swampman thought experiment, according to which a bolt of lightning randomly assembles a physical duplicate of a person, including one's neurological structure. The Swampman would have no design plan and as such would constitute a counterexample (...) to Plantinga's epistemology. Plantinga responded to Sosa that the Swampman may not be metaphysically possible so he is not disturbed by it conflicting with his epistemology and, at any rate, we would still ascribe functions (and thus design plants) the Swampman's organs and systems. In this essay I will argue that 1) a stronger case can be made demonstrating that the Swampman is not metaphysically possible and 2) at any rate the Swampman is not possible in an epistemological sense; that is, it could not know anything.

Symbiosis plays a fundamental role in contemporary biology, as well as in recent thinking in philosophy of biology. The discovery of the importance and universality of symbiotic associations has brought new light to old debates in the field, including issues about the concept of biological individuality. An important aspect of these debates has been the formulation of the hologenome concept of evolution, the notion that holobionts are units of natural selection in evolution. This review examines the philosophical assumptions that underlie (...) recent proposal of the hologenome concept of evolution, and traces those debates back in time to their historical origins, to the moment when the connection between the topics of symbiosis and biological individuality first caught the attention of biologists. The review is divided in two parts. The first part explores the historical origins of the connection between the notion of symbiosis and the concept of biological individuality, and emphasizes the role of A. de Bary, R. Pound, A. Schneider and C. Merezhkowsky in framing the debate. The second part examines the hologenome concept of evolution and explores four parallelisms between contemporary debates and the debates presented in the first part of the essay, arguing that the different debates raised by the hologenome concept were already present in the literature. I suggest that the novelty of the hologenome concept of evolution lies in the wider appreciation of the importance of symbiosis for maintaining life on Earth as we know it. Finally, I conclude by suggesting the importance of exploring the connections among contemporary biology, philosophy of biology and history of biology in order to gain a better understanding of contemporary biology.

Contemporary biological research has suggested that some host–microbiome multispecies systems (referred to as “holobionts”) can in certain circumstances evolve as unique biological individual, thus being a unit of selection in evolution. If this is so, then it is arguably the case that some biological adaptations have evolved at the level of the multispecies system, what we call hologenomic adaptations. However, no research has yet been devoted to investigating their nature, or how these adaptations can be distinguished from adaptations at the (...) species-level (genomic adaptations). In this paper, we cover this gap by investigating the nature of hologenomic adaptations. By drawing on the case of the evolution of sanguivory diet in vampire bats, we argue that a trait constitutes a hologenomic adaptation when its evolution can only be explained if the holobiont is considered the biological individual that manifests this adaptation, while the bacterial taxa that bear the trait are only opportunistic beneficiaries of it. We then use the philosophical notions of emergence and inter-identity to explain the nature of this form of individuality and argue why it is special of holobionts. Overall, our paper illustrates how the use of philosophical concepts can illuminate scientific discussions, in the trend of what has recently been called metaphysics of biology. (shrink)

Given one conception of biological individuality (evolutionary, physiological, etc.), can a holobiont – that is the host + its symbiotic (mutualistic, commensalist and parasitic) microbiome – be simultaneously a biological individual and an ecological community? Herein, we support this possibility by arguing that the notion of biological individuality is part‐dependent. In our account, the individuality of a biological ensemble should not only be determined by the conception of biological individuality in use, but also by the biological characteristics of the part (...) of the ensemble under investigation. In the specific case of holobionts, evaluations of their individuality should be made either host‐relative or microbe‐relative. We support the claim that biological individuality is part‐dependent by drawing upon recent empirical evidence regarding the physiology of hosts and microbes, and the recent characterization of the ‘demibiont’. Our account shows that contemporary disagreements about the individuality of the holobiont derive from an incorrect understanding of the ontology of biological individuality. We show that collaboration between philosophers and biologists can be very fruitful in attempts to solve some contemporary biological debates. (shrink)

Bourrat and Griffiths :33, 2018) have recently argued that most of the evidence presented by holobiont defenders to support the thesis that holobionts are evolutionary individuals is not to the point and is not even adequate to discriminate multispecies evolutionary individuals from other multispecies assemblages that would not be considered evolutionary individuals by most holobiont defenders. They further argue that an adequate criterion to distinguish the two categories is fitness alignment, presenting the notion of fitness boundedness as a criterion that (...) allows divorcing true multispecies evolutionary individuals from other multispecies assemblages and provides an adequate criterion to single out genuine evolutionary multispecies assemblages. A consequence of their criterion is that holobionts, as conventionally defined by hologenome defenders, are not evolutionary individuals except in very rare cases, and for very specific host-symbiont associations. This paper is a critical response to Bourrat and Griffiths’ arguments and a defence of the arguments presented by holobiont defenders. Drawing upon the case of the hologenomic basis of the evolution of sanguivory in vampire bats, I argue that Bourrat and Griffiths overlook some aspects of the biological nature of the microbiome that justifies the thesis that holobionts are evolutionarily different to other multispecies assemblages. I argue that the hologenome theory of evolution should not define the hologenome as a collection of genomes, but as the sum of the host genome plus some traits of the microbiome which together constitute an evolutionary individual, a conception I refer to as the stability of traits conception of the hologenome. Based on that conception I argue that the evidence presented by holobiont defenders is to the point, and supports the thesis that holobionts are evolutionary individuals. In this sense, the paper offers an account of the holobiont that aims to foster a dialogue between hologenome advocates and hologenome critics. (shrink)

A lexicographical entry on "Ernest Sosa".

Testimony is a crucial source of knowledge: we are to a large extent reliant upon what others tell us. It has been the subject of much recent interest in epistemology, and this volume collects twelve original essays on the topic by some of the world's leading philosophers. It will be the starting point for future research in this fertile field. Contributors include Robert Audi, C. A. J. Coady, Elizabeth Fricker, Richard Fumerton, Sanford C. Goldberg, Peter Graham, Jennifer Lackey, Keith Lehrer, (...) Richard Moran, Frederick F. Schmitt, Ernest Sosa, and James Van Cleve. (shrink)

This volume provides the reader with exclusive insights into Ernest Sosa’s latest ideas as well as main aspects of his philosophical work of the last 50 years. Ernest Sosa, one of the most distinguished contemporary philosophers, is best known for his ground-breaking work in epistemology, and has also contributed greatly to metaphysics, metaphilosophy and philosophy of language.

Holobionts are symbiotic assemblages composed by a host plus its microbiome. The status of holobionts as individuals has recently been a subject of continuous controversy, which has given rise to two main positions: on the one hand, holobiont advocates argue that holobionts are biological individuals; on the other, holobiont detractors argue that they are just mere chimeras or ecological communities, but not individuals. Both parties in the dispute develop their arguments from the framework of the philosophy of biology, in terms (...) of what it takes for a “conglomerate” to be considered an interesting individual from a biological point of view. However, the debates about holobiont individuality have important ontological implications that have remained vaguely explored from a metaphysical framework. The purpose of this paper is to cover that gap by presenting a metaphysical approach to holobionts individuality. Drawing upon a conception of natural selection that puts the focus on the transgenerational recurrence of the traits and that supports the thesis that holobionts are units of selection, we argue that holobionts bear emergent traits and exert downward powers over the entities that compose them. In this vein, we argue, a reasonable argument can be made for conceiving holobionts as emergent biological individuals. (shrink)

Abstract: Ernest Sosa has done important work on epistemic circularity, epistemic virtue, and reflective knowledge. He holds that epistemic circularity need not be vicious and need not prevent us from knowing that our ways of forming beliefs are reliable. In this article, I briefly explore Sosa's defense of this view and raise some questions about what is required for reflective knowledge.

In my remarks, I discuss Sosa's attempt to deal with the sceptical threat posed by dreaming. Sosa explores two replies to the problem of dreaming scepticism. First, he argues that, on the imagination model of dreaming, dreaming does not threaten the safety of our beliefs. Second, he argues that knowledge does not require safety, but a weaker condition which is not threatened by dreaming skepticism. I raise questions about both elements of his reply.

Abstract: Ernest Sosa has recently articulated an insightful response to skepticism and, in particular, to the dream argument. The response relies on two independent moves. First, Sosa offers the imagination model of dreaming according to which no assertions are ever made in dreams and no beliefs are involved there. As a result, it is possible to distinguish dreaming from being awake, and the dream argument is blocked. Second, Sosa develops a virtue epistemology according to which in appropriately (...) normal conditions our perceptual beliefs will be apt. Hence, in these conditions, we will have at least animal knowledge, and the conclusion of the dream argument is undermined. In this article, I examine various moves that the skeptic can make to resist Sosa's challenge, and I contrast the proposal to a neo-Pyrrhonian stance. In the end, there is surprisingly little disagreement about the status of ordinary perceptual beliefs in the two stances. (shrink)

Ernest Sosa presents a new approach to the problems of knowledge and scepticism.

Philosophical Papers, Volume 40, Issue 3, Page 341-358, November 2011.

In recent work, Sosa proposes a comprehensive account of epistemic value based on an axiology for attempts. According to this axiology, an attempt is better if it succeeds, better still if it is apt (i.e., succeeds through competence), and best if it is fully apt, (i.e., guided to aptness by apt beliefs that it would be apt). Beliefs are understood as attempts aiming at the truth. Thus, a belief is better if true, better still if apt, and best if (...) fully apt. I raise a Kantian obstacle for Sosa’s account, arguing that the quality or worth of an attempt is independent of whether it succeeds. In particular, an attempt can be fully worthy despite being a failure. I then consider whether Sosa’s competence-theoretic framework provides the resources for an axiology of attempts that does not place so much weight on success. I discuss the most promising candidate, an axiology grounded in the competence of attempts, or what Sosa calls adroitness. An adroit attempt may fail. I raise doubts about whether an adroitness-based axiology can provide a plausible explanation of the worthiness of subjects’ beliefs in epistemically unfortunate situations, such as the beliefs of the brain in a vat. I conclude by speculating that the notion of a belief’s fit with what the subject has to go on, a notion missing from Sosa’s competence-theoretic framework, is crucial to explaining epistemic worth.
