In “Global Knowledge Frameworks and the Tasks of Cross-Cultural Philosophy,” Leigh Jenco searches for the conception of knowledge that best justifies the judgment that one can learn from non-local traditions of philosophy. Jenco considers four conceptions of knowledge, namely, in catchwords, the esoteric, Enlightenment, hermeneutic, and self- transformative conceptions of knowledge, and she defends the latter as more plausible than the former three. In this critical discussion of Jenco’s article, I provide reason to doubt the self-transformative conception, and also advance (...) a fifth, pluralist conception of knowledge that I contend best explains the prospect of learning from traditions other than one’s own.

The point of this symposium is to locate one trajectory of the new wave of discussions about beauty beyond the customary confines of analytic aesthetics and to situate it at the intersection of aesthetics, ethics, social-political philosophy, and cultural criticism. Three essays follow this introduction authored by Marica Muelder Eaton, Paul C. Taylor, and Susan Bordo. They represent a conjoined effort to move 'beauty' beyond the traditional parameters of past contextual theories of art. This introductory essay offers some guidance (...) as to why a symposium on beauty merits attention in 1999. (shrink)

Précis for a book symposium, with contributions from Meg Wallace, Louis deRosset, and Chris Tillman and Joshua Spencer.

This paper defends an intellectualist interpretation of Diotima’s speech in Plato’s Symposium. I argue that Diotima’s purpose, in discussing the lower lovers, is to critique their erōs as aimed at a goal it can never secure, immortality, and as focused on an inferior object, themselves. By contrast, in loving the form of beauty, the philosopher gains a mortal sort of completion; in turning outside of himself, he also ceases to be preoccupied by his own incompleteness.

This is a report on the II Symposium Platonicum, which took place in Perugia, Italy, September 1-6, 1989, and on the founding of the International Plato Society, which took place in Bevagna, Province of Perugia, Umbria, Italy, September 3, 1989.

El contenido de la presente discusión de Análisis Filosófico surge a partir de diversas actividades organizadas por mí en SADAF y en la UBA. En primer lugar, Roy Cook dictó en SADAF el seminario de investigación intensivo On Yablo's Paradox durante la última semana de julio de 2011. En el seminario, el profesor Cook presentó el manuscrito aún sin finalizar de su libro The Yablo Paradox: An Essay on Circularity, Oxford, Oxford UP, (en prensa). Extensas y apasionantes discusiones ocurrieron durante (...) esos encuentros sobre circularidad y construcciones infinitarias. Fue en ese tiempo, donde me surgió la idea de editar una discusión sobre las ideas que Cook defiende en ese trabajo. El proyecto era una extensión natural del trabajo que veníamos realizando con mi grupo de investigación en temas vinculados al concepto de verdad, autorreferencia y paradojas. Luego, durante el segundo cuatrimestre de 2011, dicté el seminario La paradoja de Yablo, en el instituto de filosofía de la UBA. Algunos de los borradores de los artículos que aparecen en el presente volumen tienen su origen en este curso. Finalmente, invité por segunda vez al profesor Cook al Symposium on Yablo's Paradox realizado en SADAF en julio de 2012. En esta oportunidad, se presentaron las versiones finales de los artículos de Lavinia Picollo, Paula Teijeiro, Federico Pailos, Diego Tajer, Lucas Rosenblatt e Ignacio Ojea que se incluyen a continuación. El encuentro incluyó las inteligentes réplicas del profesor Cook y profundas discusiones sobre los mencionados temas lógicosemánticos. Quiero agradecer a todos los integrantes del Gaf[log] que participaron activamente en las mencionadas actividades, ya sea en la publicación posterior o en los coloquios y seminarios que le dieron origen. Agradezco al Comité editorial de Análisis Filosófico, en especial a Alberto Moretti, quienes apoyaron desde sus comienzos este proyecto. Finalmente, y de manera especial, quiero expresar mi gratitud al profesor Roy Cook, quien no sólo apoyó e inspiró el proyecto desde sus comienzos, sino que además compartió generosamente sus ideas y las discutió con estimulante pasión.

This is a short introduction to a book symposium on Paul Gowder's recent book, _The Rule of Law in thee Real World_ (Cambridge University Press, 2016). The book symposium will appear in the St. Luis University Law Journal, 62 St. Louis U. L.J., -- (2018), with commentaries on Gowder's book by colleen Murphy, Robin West, Chad Flanders, and Matthew Lister, along with replies by Paul Gowder.

Descartes, the textbooks say, divided human beings, or at least their minds, from the natural world. This is not just the consequence of metaphysical dualism, but of the concomitant indirect ‘ideas’ theory of perception. On the standard view, the soul must dimly infer the nature of the external world from the meagre, fragmentary, and often misleading input which is causally transmitted from objects through the nervous system to the brain and, ultimately, to the pineal gland. The metaphysical solipsism of the (...) cogito, on this picture, has its psychophysiological counterpart in the way Descartes sets all goings-on in nature at such a distance from the knowing subject who is temporarily and imperfectly united with a physical body. We cannot be sure, after all, that there are human beings rather than mere automata under the hats and cloaks we see from our window. (shrink)

In Replacing Truth, Scharp takes the concept of truth to be fundamentally incoherent. As such, Scharp reckons it to be unsuited for systematic philosophical theorising and in need of replacement – at least for regions of thought and talk which permit liar sentences and their ilk to be formulated. This replacement methodology is radical because it not only recommends that the concept of truth be replaced, but that the word ‘true’ be replaced too. Only Tarski has attempted anything like it (...) before. I dub such a view Conceptual Marxism. In assessing this view, my goals are fourfold: to summarise the many components of Scharp’s theory of truth; to highlight what I take to be some of the excess baggage carried by the view; to assess whether, and to what extent, the extreme methodology on offer is at all called for; finally, to briefly propose a less radical replacement strategy for resolving the liar paradox.

Mark Pennington’s Robust Political Economy is a systematic exposition of a framework for analyzing institutional performance. The Robust Political Economy framework evaluates institutions according to their ability to solve knowledge and incentive problems. On grounds of robustness, Pennington combines insights from Austrian market-process theory and public-choice theory to defend classical liberalism from several compelling critiques. These include theories of market failure in economics; communitarian, deliberative-democratic, and liberal-egalitarian theories of justice; and concerns with social capital, domestic and international poverty, and ecology.

This paper introduces a symposium on Equality versus Priority. It explains how cases involving risk are key to distinguishing these views and discusses a 'social egalitarian' critique of both 'telic egalitarians' and 'telic prioritarians'.

MICHELLE MARDER KAMHI offers an in-depth response to The Aesthetics Symposium. In addition to answering many of the contributors’ objections to What Art Is: The Esthetic Theory of Ayn Rand, she offers a critique of their own theses—in particular, Barry Vacker’s claim that chaos theory is implicit in Rand’s aesthetics, Jeff Riggenbach’s argument that much of Rand’s theory was anticipated by Susanne Langer and Stephen Pepper, and Roger Bissell’s suggestion that the concept of a microcosm be applied to Rand’s (...) view of the function of art.

This is the introduction to the Journal of Global Ethics symposium on Peter Singer's The Most Good You Can Do: How Effective Altruism is Changing Ideas About Living Ethically. It summarizes the main features of effective altruism in the context of Singer's work on the moral demands of global poverty and some recent criticisms of effective altruism. The symposium contains contributions by Anthony Skelton, Violetta Igneski, Tracy Isaacs and Peter Singer.

The paper claims that we cannot understand properly Platonic conception of love and friendship unless we read the Lysis in the light of the Symposium and vice verse. Dealing with the crucial question of what made Plato write two different dialogues on the same topic, it advocates an alternative intertextual reading that does not deny progress of Plato’s thinking. Though the Symposium offers, in comparison to the Lysis, a more developed philosophical theory of love, Plato still has good (...) reasons to articulate the dilemmas presented in the Lysis. Combining the contrast in dialogue endings with the similarity in structure and in argumentation, Plato makes clear that, between the Lysis and the Symposium, there is progress and constancy at the same time: while the Symposium gives a philosophical account of what we can call “divine love”, it accepts and even emphasizes the insight of the Lysis that philosophical love can imply lack of what we usually consider worth loving. Plato in the Symposium does not discard “human love” and does not conceal possible troubles of philosophical, i.e. divine love. Therefore, the critique of Plato as being champion of impersonal or “ideal” love is unpersuasive. (shrink)

In this paper I investigate the understanding of eros expressed in the speeches of Phaedrus and Agathon in Plato’s Symposium, two speeches often neglected in the literature. I argue that they contain crucial insights about the nature of eros that reappear in Diotima’s speech. Finally, I consider the relation of Socrates and Alcibiades in light of these insights, arguing that the figure of Alcibiades should be seen as a negative illustration of the notion of erotic education described by Diotima.

This volume consists of the invited papers presented at the 23rd International Wittgenstein Conference held in Kirchberg, Austria in August 2000. Among the topics treated are: truth, psychologism, science, the nature of rational discourse, practical reason, contextualism, vagueness, types of rationality, the rationality of religious belief, and Wittgenstein. Questions addressed include: Is rationality tied to special sorts of contexts? ls rationality tied to language? Is scientific rationality the only kind of rationality? Is there something like a Western rationality? and: Could (...) we genetically engineer human beings to be less wicked? (shrink)

A commentary on the Symposium as a challenge and a gift to Athens. I begin with a reflection on three dates: 416 bce, the date of Agathon’s victory party, c. 400, the approximate date of Apollodorus’ retelling of the party, and c. 375, the approximate date of the ‘publication’ of the dialogue, and I argue that Plato reminds his contemporary Athens both of its great poetic and legal and scientific traditions and of the historical fact that the way late (...) fourth century Athens appropriated them in some way led to the city’s demise at the turn of the century; thus the dialogue is Plato’s challenge to his contemporary Athens to recognize and overcome its flawed relation to its cultural resources. Heard in this way, the key moments are Aristophanes’ implied critique of Pausanias and Eryximachus and Socrates’ implied critique of Aristophanes and Agathon. Proceeding by a close reading, I argue that Plato exposes, for those moved to rise to his challenge, the failure of his great predecessors to conceive the divine in a way that, worthy of the height and otherness divinity requires, can provide substantive orientation for the burgeoning new reason that animates the city’s culture.

In this essay, I propose a reading of two contrasting passions, two kinds of erōs, in the "Symposium." On the one hand, there is the imperialistic desire for conquering and possessing that Alcibiades represents; and on the other hand, there is the productive love of immortal wisdom that Diotima represents. It’s not just what Alcibiades says in the Symposium, but also what he symbolizes. Alcibiades gives a speech in honor of Socrates and of his unrequited love for him, (...) but even here Alcibiades recounts his attempted seduction of Socrates as a failed conquest, as an unsuccessful attempt to violently take possession of something that Socrates has within him. Even more importantly, in 416 BCE (the dramatic date of Agathon’s symposium) Alcibiades was soon to encourage his fellow countrymen to set off on the ruinous Sicilian expedition. Alcibiades’s actions behind-the-scenes of the "Symposium" reveal the clearest manifestation of his imperialistic erōs (for political power in Athens). They also constitute some necessary background to the dialogue, which Plato’s Athenian readers would have had in mind. Where else can we catch a glimpse of this disastrous desire? It is best illustrated in Thucydides’s "History." I show that the beginnings of this political passion can already be seen in Pericles’s funeral oration (2.35-46, specifically 2.43.1) and that after Pericles’s death, Alcibiades stokes this erōs to such a fevered pitch that the Athenians agree to launch the tragic venture against Sicily. Opposed to this political passion, is Diotima’s. She tries to reorient this misguided erōs and presents an alternative form of desire for everlasting wisdom (philosophia). (shrink)

As its title suggests, this anthology is a collection of papers presented at a conference on feelings and emotions held in Amsterdam in 2001. One of the symposium’s main goals was to draw some of the most prominent researchers in emotion research together and provide a multi-disciplinary ‘snap shot’ of the state of the art at the turn of the century. In that respect it is truly a cognitive science success story. There are articles from a wide range of (...) fields, encompassing, e.g., philosophy, neuroscience, anthropology, sociology, and psychology. Another goal was to emulate a series of conferences of the same name that had taken place in the early parts of the 20th Century. Included in the book are the title pages of these other conferences, which put the symposium in a nice historical context. The conference seems to have met both goals. It does, for instance, offer a vital snap shot of the state of emotions research at the turn of the century, though this does not mean that it is best suited for the annals of history. This volume will provide anyone interested in the cognitive science of the emotions a clear indication of where the field has come from, and insight into where it will be going. (shrink)

A crux of Plato’s Symposium is how beauty relates to the good. Diotima distinguishes beauty from the good, I show, to explain how erotic pursuits are characteristically ambivalent and opaque. Human beings pursue beauty without knowing why or thinking it good; yet they are rational, if aiming at happiness. Central to this reconstruction is a passage widely taken to show that beauty either coincides with the good or demands disinterested admiration. It shows rather that what one loves as beautiful (...) does not appear good, a proposal with ramifications for ethical psychology. (shrink)

The paper argues that thumos, which is never explicitly mentioned as a part of the soul in the Symposium, plays a major role in the dialogue. In light of the Republic’s characterization of thumos as the source of emotions such as of love of honor, love of victory, admiration for courage, shame, anger, and the propensity to become indignant at real or imaginary wrongs, the paper argues that both Phaedrus’ speech and the speech of Alcibiades are shaped by thumoeidetic (...) motivations. While Phaedrus’ stress on shame, honor, glory and courage aims at proving that Eros inspires virtue, the speech of Alcibiades shows that thumoeidetic motivations are not sufficient to shape a noble character. The dependence on recognition, the ambiguous role played by shame, and the tension between what is admirable and what just happens to be admired are implicit shortcomings in Phaedrus’ speech. When the same themes come back in Alcibiades’ speech they work as negative counterpoints to Phaedrus’ main arguments. Alcibiades’ obsession with power and victory dominates his ambivalent encomium of Socrates. The speech does not reveal who Socrates really is. Rather, it shows how the philosophical life can be misunderstood when reason’s best ally takes over in the souls of men. (shrink)

Irene McMullin’s Existential Flourishing (Cambridge University Press, 2018) weaves together virtue ethics and existential phenomenology: the influence of Heidegger and Levinas, in particular, is clear throughout. This paper provides a summary of McMullin’s elegantly argued position and raises a number of possible concerns, particularly regarding the interaction of Aristotelian and Phenomenological assumptions. I focus specifically on the role of the 2nd-person perspective, on the links between exemplars and socialisation, and on the problem of those who, as Nietzsche put it, “are (...) both evil and happy – a species on which the moralists are silent”.

The paper deals with the "deuteros plous", literally ‘the second voyage’, proverbially ‘the next best way’, discussed in Plato’s "Phaedo", the key passage being Phd. 99e4–100a3. The second voyage refers to what Plato’s Socrates calls his “flight into the logoi”. Elaborating on the subject, the author first (I) provides a non-standard interpretation of the passage in question, and then (II) outlines the philosophical problem that it seems to imply, and, finally, (III) tries to apply this philosophical problem to the "ultimate (...) final proof" of immortality and to draw an analogy with the ontological argument for the existence of God, as proposed by Descartes in his 5th "Meditation". The main points are as follows: (a) the “flight into the logoi” can have two different interpretations, a common one and an astonishing one, and (b) there is a structural analogy between Descartes’s ontological argument for the existence of God in his 5th "Meditation" and the "ultimate final proof" for the immortality of the soul in the "Phaedo".

Mimesis can refer to imitation, emulation, representation, or reenactment - and it is a concept that links together many aspects of ancient Greek Culture. The Western Greek bell-krater on the cover, for example, is painted with a scene from a phlyax play with performers imitating mythical characters drawn from poetry, which also represent collective cultural beliefs and practices. One figure is shown playing a flute, the music from which might imitate nature, or represent deeper truths of the cosmos based upon (...) Pythagorean views (which were widespread in Western Greece at the time). The idea that mimesis should be restricted to ideals was made famous by Plato (whose connections to Pythagoreanism and Siracusa are well-known), and famously challenged by his student Aristotle (not to mention by the mimetic character of Plato’s own poetry). This volume gathers essays not only on the philosophical debate about mimesis, but also on its use in architecture, drama, poetry, history, music, ritual, and visual art. The emphasis is on examples from Hellenic cities in Southern Italy and Sicily, but the insights apply far beyond – even to modern times. Contributors include: Thomas Noble Howe, Francisco J. Gonzalez, Gene Fendt, Guilherme Domingues da Motta, Jeremy DeLong, Carolina Araújo, Marie-Élise Zovko, Lidia Palumbo, Sean Driscoll, Konstantinos Gkaleas, Anna Motta, Jure Zovko, Alexander H.

In this paper, I offer a new interpretation of Aristophanes’ speech in Plato’s Symposium. Though Plato deliberately draws attention to the significance of Aristophanes’ speech in relation to Diotima’s (205d-206a, 211d), it has received relatively little philosophical attention. Critics who discuss it typically treat it as a comic fable, of little philosophical merit (e.g. Guthrie 1975, Rowe 1998), or uncover in it an appealing and even romantic treatment of love that emphasizes the significance of human individuals as love-objects to (...) be valued for their own sakes (e.g. Dover 1966, Nussbaum 1986). Against the first set of interpreters, I maintain that Aristophanes’ speech is of the utmost philosophical significance to the dialogue; in it, he sets forth a view of eros as a state of lack and a corresponding desire for completion, which is the starting-point for Diotima’s subsequent analysis. Against the second, I argue that Aristophanes’ speech contains a profoundly pessimistic account of eros. Far from being an appreciative response to the individuality of the beloved, eros, for Aristophanes, is an irrational urge, incapable of satisfaction. It is this irrationality that precludes Aristophanes’ lovers from achieving the partial satisfaction of erotic desire that is open to their Socratic counterparts through their relationship to the forms.

A symposium on my *Objects: Nothing Out of the Ordinary* (2015). In response to Wallace, I attempt to clarify the dialectical and epistemic role that my arguments from counterexamples were meant to play, I provide a limited defense of the comparison to the Gettier examples, and I embrace the comparison to Moorean anti-skeptical arguments. In response to deRosset, I provide a clearer formulation of conservatism, explain how a conservative should think about the interaction between intuition and science, and discuss (...) what conservatives should say about scattered territories, clonal colonies, and arbitrary systems. In response to Tillman and Spencer, I fortify my original presentation of the debunking arguments by clarifying why, even while trees (if they exist) are paradigmatically causal, conservatives are meant to be rationally obstructed from believing that it is trees that are causing our tree beliefs.

Symposium contribution on Mark Schroeder's Slaves of the Passions. Argues that Schroeder's account of agent-neutral reasons cannot be made to work, that the limited scope of his distinctive proposal in the epistemology of reasons undermines its plausibility, and that Schroeder faces an uncomfortable tension between the initial motivation for his view and the details of the view he develops.

Like human existence itself, our enduring legacies—whether poetic, ethical, political, or philosophical—continually unfold and require recurrent communal engagement and (re)enactment. In other words, an ongoing performance of significant works must occur, and this task requires the collective human activity of re-membering or gathering-together-again. In the Symposium, Diotima provides an account of human pursuits of immortality through the creation of artifacts, including laws, poems, and philosophical discourses that resonates with Gadamer’s account of our engagement with artworks and texts. This essay (...) explores common places among Gadamer and Plato; however, it does so through the complex character of Diotima the philosopher-priestess. Diotima’s teaching on the processive character of human existence and her understanding of knowledge as dynamic has been largely ignored. Given Gadamer’s historically oriented philosophical hermeneutics, not to mention his creative and critical engagement with Platonic themes such as beauty, recollection, and art, Diotima makes for an especially fruitful dialogue partner.

A contribution to a symposium on Herman Cappelen's Philosophy without Intuitions.

This essay proposes that Socrates practiced various spiritual exercises, including meditation, and that this Socratic practice of meditation was habitual, aimed at cultivating emotional self-control and existential preparedness. Contemporary research in neurobiology supports the view that intentional mental actions, including meditation, have a profound impact on brain activity, neuroplasticity, and help engender emotional self-control. This impact on brain activity is confirmed via technological developments, a prime example of how technology benefits humanity. Socrates attains the balanced emotional self-control that Alcibiades describes (...) in the Symposium because of the sustained mental effort he exerts that directly impacts his brain and his emotional and philosophical life. The essay concludes that Socratic meditative practices aimed at manifesting true dignity as human beings within the complexities of a technological world offer a promising model of self-care worthy of embracing today.
