Walter Sinnott-Armstrong argues that moral disagreement and widespread moral bias pose a serious problem for moral intuitionism. Seneca’s view that we just recognise the good could be criticised using a similar argument. His approach to argumentation offers a way out, one that may serve as a model for a revisionary intuitionism.

En este trabajo defenderé que los erísticos del Eutidemo se dedican a la sofística tal como esta es definida en el Sofista. Propondré que en tanto la quinta y la séptima definición se sirven del concepto de ἀντιλογικός, ambas son capaces de capturar el componente dialéctico y refutativo de la práctica erística. Preferiré indentificarlos con la séptima no sólo porque constituye la definición final del sofista, sino también porque esta incluye entre sus determinaciones el empleo engañoso de tal forma de (...) argumentación, rasgo que se ajusta más a la erística que el cobro de dinero, elemento principal de la quinta.

RESUMEN Una interpretación extendida del Eutidemo sostiene que la práctica erística de la cual Platón busca distanciarse en el diálogo constituye una referencia velada a la dialéctica desarrollada por el socrático Euclides y sus seguidores megáricos. No obstante, los expertos reconocen que la segunda demostración erística pone en boca de Eutidemo y Dionisodoro dos posiciones que fueron defendidas por Antístenes, según las cuales no es posible decir falsedades ni contradecir. Este trabajo busca analizar las refutaciones de dicha sección y confrontarlas (...) con los testimonios sobre Antístenes a fin de evaluar hasta qué punto nos encontramos en presencia de los mismos argumentos. Defenderé que si bien las refutaciones del Eutidemo poseen una inspiración antisténica, principalmente respecto de las tesis que buscan sostener, las mismas se basan en una serie de supuestos ambiguos que responden más a los lineamientos de la práctica erística que a los fundamentos del pensamiento antisténico. Argumentaré, asimismo, que esta diferencia podría explicarse a partir del hecho de que el Eutidemo puede ser leído como una respuesta al Encomio de Helena de Isócrates, en donde este ataca a los socráticos por dedicarse a la erística y al desarrollo de doctrinas paradójicas, entre las cuales incluye las tesis de Antístenes. ABSTRACT A widespread interpretation of the Euthydemus claims that the Eristic practice from which Plato seeks to distance himself in the dialogue constitutes a veiled reference to the dialectics developed by the Socratic Euclid and his Megarian followers. However, experts acknowledge that the second Eristic demonstration puts two positions in the mouth of Euthydemus and Dionysodorus which were defended by Antisthenes, according to which it is not possible to say falsehoods nor to contradict. This work seeks to analyze the refutations of this section and compare them with the testimonies about Antisthenes in order to evaluate to what extent they are the same arguments. I will defend that although the refutations of the Euthydemus have an Antisthenic inspiration, mainly with respect to the theses they seek to support, these are based on a series of ambiguous assumptions that correspond more to the principles of Eristics than to the grounds of Antisthenic thought. I will also argue that the difference could be explained by the fact that the Euthydemus can be understood as a response to Isocrates ’ Encomium of Helen, where he attacks the whole Socratic circle for devoting to Eristics and to the development of paradoxical doctrines, including the theses of the Antisthesis.

Una larga tradición le atribuye a Sócrates la preocupación por transformar la vida de quienes dialogan con él; atribución que se opone a la imagen, rastreable en los Diálogos de Platón, de su fracaso al momento de influir en la vida de sus interlocutores más recalcitrantes. Para disminuir esta tensión y, con ello, disolver la impresión de dicho fracaso, se examinan elementos de la representación platónica del élenchos en favor de la idea de que Sócrates no busca convertir a los (...) demás. Al final, se añade una crítica al optimismo con que Pierre Hadot sí le adjudica la función de agente de conversión. (shrink)

After presenting the rules of Eleatic antilogic, i.e., dialectic, I argue that Zeno was a practitioner, and, on the basis of key passages from Plato’s Parmenides, that his paradoxes of divisibility and movement were notreductio ad absurdum, but simple derivation of impossibilities meant to ridicule Parmenides’ adversaries. Thus, Zeno did not try to prove that there is no motion, but simply derived this consequence from premises held by his opponents. I argue further that these paradoxes were devised, in accordance with (...) Eleatic antilogic, following a scheme that included hypotheses and their contradictories, within which the subject is to be treated both “in relation to itself,” and “in relation to other things”.

In this paper we provide an interpretation of Aristotle's rule for the universal quantifier in Topics Θ 157a34–37 and 160b1–6 in terms of Paul Lorenzen's dialogical logic. This is meant as a contribution to the rehabilitation of the role of dialectic within the Organon. After a review of earlier views of Aristotle on quantification, we argue that this rule is related to the dictum de omni in Prior Analytics A 24b28–29. This would be an indication of the dictum’s origin in (...) the context of dialectical games. One consequence of our approach is a novel explanation of the doctrine of the existential import of the quantifiers in dialectical terms. After a brief survey of Lorenzen's dialogical logic, we offer a set of rules for dialectical games based on previous work by Castelnérac and Marion, to which we add here the rule for the universal quantifier, as interpreted in terms of its counterpart in dialogical logic. We then give textual evidence of the use of that rule in Plato's dialogues, thus showing that Aris... (shrink)

Aristotle'sSophistical Refutations(=Soph. el.) seeks to uncover the workings of apparent deductive reasoning, and is thereby largely devoted to the caricature of dialectic that the ancients callederistic(ἐριστική), the art of quarrelling. Unlike antilogy (ἀντιλογία), which refers to a type of argumentation where two arguments are pitted against each other in a contradictory manner, eristic takes on in Aristotle an exclusively pejorative meaning, as is made clear, for example, by this passage fromSoph. el.: ‘For just as unfairness in a contest is a (...) definite type of fault, and is a kind of foul fighting, so the art of contentious reasoning is foul fighting in disputation.’.

In this paper, I highlight the significance of practices of _refutation_ in philosophical inquiry, that is, practices of showing that a claim, person or theory is wrong. I present and contrast two prominent approaches to philosophical refutation: refutation in ancient Greek dialectic (_elenchus_), in its Socratic variant as described in Plato’s dialogues, and as described in Aristotle’s logical texts; and the practice of providing counterexamples to putative definitions familiar from twentieth century analytic philosophy, focusing on the so-called Gettier problem. Moreover, (...) I discuss Lakatos’ method of proofs and refutations, as it offers insightful observations on the dynamics between arguments, refutations, and counterexamples. Overall, I argue that dialectic, in particular in its Socratic variant, is especially suitable for the philosophical purpose of questioning the obvious, as it invites reflection on one’s own doxastic commitments and on the tensions and inconsistencies within one’s set of beliefs. By contrast, the counterexample-based approach to philosophical refutation can give rise to philosophical theorizing that is overly focused on hairsplitting disputes, thus becoming alienated from the relevant human experiences. Insofar as philosophical inquiry treads the fine line between questioning the obvious while still seeking to say something significant about human experiences, perhaps a certain amount of what Lakatos describes as ‘monster-barring’—a rejection of overly fanciful, artificial putative counterexamples—has its place in philosophical argumentation.

This paper is devoted to the Parmenides’ methodological preamble, in which Parmenides teaches how one is to lead a dialectical inquiry. The method presented there recalls the goddess’s advice, as presented by the historical Parmenides in his Poem, to think “the way of being and the way of non-being.” In Plato’s Parmenides, these two ways are seen as manners of examining a hypothesis. I explain that the method is exhaustive insofar as it requires repeatedly asking what the consequences are if (...) a thing does exist, or does not. Lastly, I suggest that the method should be distinguished from other dialectical practices found in Plato’s work. (shrink)

What role, if any, does dialectic play in Aristotle’s epistemology in the Topics? In this paper I argue that it does play a role, but a role that is independent of endoxa. In the first section, I sketch the case for thinking that dialectic plays a distinctively epistemological role—not just a methodological role, or a merely instrumental role in getting episteme. In the second section, I consider three ways it could play that role, on two of which endoxa play at (...) least a co-starring role. But in the third section, I argue that endoxa don’t play that co-starring role, by arguing for a deflationary account of what endoxa are. For that reason, the third view emerges as the most plausible; but the third view is, I’ll suggest, Platonic. (shrink)

Platonic arguments often have premises of a particular form which is misunderstood. These sentences look like universal generalizations, but in fact involve an implicit qua phrase which makes them a fundamentally different kind of predication. Such general implicit redoubled qua predications (girqps) are not an expression of Plato's proprietary views; they are also very common in everyday discourse. Seeing how they work in Plato can help us to understand them.

An introduction to philosophy of language since Frege, focusing on the 20th century.

In a crucial passage in the Republic found within a discussion of women’s role in the ideal polis, division of eidē is identified as necessary for dialectic. A careful consideration of the way division is described in this passage reveals that it resembles the procedure of division described in the Phaedrus and the Sophist and that this procedure, when carried out correctly, is central to dialectic according to the Republic and helps set dialectic apart from eristic. Consideration of additional passages (...) in the Republic indicates that division may be employed on different kinds of entities, such as virtues and types of human natures; for according to the argument of the Republic, the correct use of division for the purpose of distinguishing types of human natures or virtues, entities that to the untrained eye may look alike but are distinct by nature, is required for achieving the knowledge philosophers and philosopher-rulers need. In fact, correctly performed divisions help the dialectician to bring into focus a subject matter under consideration in a kind of double-vision that reveals that matter as a concrete phenomenon that exhibits participation in different eidê when it is considered from different points of view.

My dissertation is devoted to an examination of the resolution of fallacy in Plato's Euthydemus. It is a familiar claim that the Euthydemus champions Socratic argumentation over sophistical or eristic reasoning. No consensus however exists regarding either the nature or philosophical significance of Socrates’ treatment of the fallacies he confronts. I argue that a careful reading of the dialogue reveals that the Socratic response to fallacious reasoning is conducted at two different levels of philosophical sophistication. Socrates relies upon the resources (...) of Socratic dialectic in responding to sophisms due to ignorance of refutation. Insofar as Socratic dialectic is grounded in a grasp of the nature of genuine refutation, the objections it raises to false refutation are fully explanatory. On the other hand, Socrates employs various self-refutation arguments against theses which depend on false assumptions regarding the nature of predication---for example, the thesis that false speaking is impossible. It is however characteristic of Socratic dialectic that this method of examination cannot explain why the sophists’ theses are false. The Socratic response to fallacy in these cases is non-explanatory in this sense. On the other hand, these limitations on Socratic expertise are overcome in other passages in the dialogue which are replete with clues to the reader that point to a genuine explanation and resolution of the sophists’ arguments for their various theses. In particular, the reader is invited at every turn to modify, clarify, or reject various assumptions made by the brothers regarding the nature of predication. Here Plato implicitly relies on the results of what I call higher dialectic. This theory, which receives explicit formulation in the Sophist, is conceptually rich enough to expose and dispose of the various false assumptions upon which the sophists’ theses rest. I conclude that the Euthydemus is concerned to identify Socratic dialectic as only a part of philosophy, and to locate and strictly delimit its epistemological status as lying above eristic and the rhetorical arts, but below that of dialectic as that is conceived in the Republic and even later dialogues---thus anticipating the Sophist’s conception of Socrates as the practitioner of a ‘noble sophistry’, and the elenchus as a propaedeutic to philosophy, which purges the soul of false beliefs.
