I argue that Meno’s Paradox targets the type of knowledge that Socrates has been looking for earlier in the dialogue: knowledge grounded in explanatory definitions. Socrates places strict requirements on definitions and thinks we need these definitions to acquire knowledge. Meno’s challenge uses Socrates’ constraints to argue that we can neither propose definitions nor recognize them. To understand Socrates’ response to the challenge, we need to view Meno’s challenge and Socrates’ response as part of a larger disagreement about the value (...) of inquiry. (shrink)

Using persuasive definitions and persuasive language generally to put a spin on an argument has often held to be suspicious, if not deceptive or even fallacious. However, if the purpose of a persuasive definition is to persuade, and if rational persuasion can be a legitimate goal, putting forward a persuasive definition can have a legitimate basis in some cases. To clarify this basis, the old subject of definitions is reconfigured into a new dialectical framework in which, it is argued, a (...) definition should be evaluated in light of its purpose as a speech act. But if persuasive definitions are so often thought to be suspect, misleading, or even fallacious, how can individual cases be judged on some objective basis? In this paper, a new dialectical method of evaluating such definitions on a case-by-case basis is proposed, showing how abusive as well as reasonable uses of persuasive language can properly be identified, analyzed and evaluated.

What are the implications of taking seriously Chaïm Perelman's proposition that “definitions are rhetorical”? Efforts to find Real Definitions are dysfunctional to the extent they direct argumentation toward pseudo “is” claims and away from explicit “ought” claims about how words are to be used. Addressing definitional disputes explicitly as propositions ofought rather thanis could put on the agenda the pragmatic concerns of definitional choice that might otherwise remain tacit.

In this paper, I ponder the question of whether Socrates follows a method of investigation — the method of hypothesis — which he advocates in Plato's Phaedo. The evidence in the dialogue suggests that he does not follow the method, which raises additional questions: If he fails to do so, why does he articulate the method? Does his statement of method affect his actions or is it mainly forgotten? Although Socrates is a fictional character, his actions in the Phaedo suggests (...) questions about the function of espoused methods in actual situations. (shrink)

In his critique of Ayn Rand: The Russian Radical, David MacGregor argues that my book trivializes dialectical method. He fails to notice the many nondialectical assumptions that pervade contemporary social theory and practice. Dialectics, as a context‐sensitive methodological orientation, can provide tools for a better grasp of systems and processes in the real world—the goal, as I understand it, of the “post‐libertarian” approach Jeffrey Friedman advocates.

In Republic VII Plato has Socrates make a curious argument: dialectic as currently practiced causes lawlessness, and thus the practice of dialectic should be restricted to those of a certain age who have been properly trained and selected (537e-539e). I argue that the warning in Republic VII points to a disagreement between the views expressed by the character `Socrates' in the Republic, and the views expressed by the character `Socrates' in the Apology. I do so by showing that Republic's description (...) of the problem as well as Plato's prescriptions for solving it can only be understood under the assumption that `dialectic' in this passage refers to questioning or refutation in general, and as such must include Socratic practices within its scope. This disagreement represents a more general disagreement about the path to the good life and the role of philosophy in living life well, and raises questions concerning Plato's opinion of the trial of Socrates.

This paper has three dimensions, historical, theoretical and social. The historical dimension is to show how the Ciceronian system of dialectical argumentation served as a precursor to computational models of argumentation schemes such as Araucaria and Carneades. The theoretical dimension is to show concretely how these argumentation schemes reveal the interdependency of rhetoric and logic, and so the interdependency of the normative with the empirical. It does this by identifying points of disagreement in a dialectical format through using argumentation schemes (...) and critical questions. The social dimension is to show how the Ciceronian dialectical viewpoint integrates with the use of computational tools that can be used to support the principle of reason-based deliberation and facilitate deliberative democracy.

The present essay aims to throw light on the study of dialectical thinking from a cultural-historical perspective. Different forms of dialectic are articulated as ideal types, including the Greek dialectic, the Hegelian dialectic, the contemporary German negative dialectic, the Chinese dialectic, and the Indian negative dialectic. These influential cultural products in the history of the East and the West, articulated as ideal types, serve as constellations that could facilitate further empirical studies on dialectical thinking. An understanding of the complexity of (...) these constellations reveals the pitfalls of investigating dialectical thinking without an appropriate conceptualization of the research target. With the ideal types of dialectic as "figure," and Vygotsky's thesis of the cultural-historical origin of higher psychological processes as "ground," we explore possibilities for further lines of inquiry on dialectical thinking. Adhering to the Scribnerian multilevel scheme that reconstructs Vygotsky's thesis, and returning to the core ideas of Vygotsky himself, we discover new, meaningful questions about the study of dialectical thinking. In the research area of "culture and cognition," consideration of a cultural-historical perspective appears to be both necessary and promising. (shrink)

In this paper, I reconsider the commonly held position that the early moral education of the Republic is arational since the youths of the Kallipolis do not yet have the capacity for reason. I argue that, because they receive an extensive mathematical education alongside their moral education, the youths not only have a capacity for reason but that capacity is being developed in their early education. If this is so, though, then we must rethink why the early moral education is (...) arational. I argue that the reason is rooted in the nature of moral explanations. These sorts of explanations are rooted in the Forms and thus one can only understand those explanations when they have knowledge of the Forms. But this requires preparation – the very sort of preparation that is provided by both the mathematical and moral educations. (shrink)

Although prima facie no more than a successful private detective, Sherlock Holmes is a classic exponent of scientific method and has laid down several fundamental rules of scientific discovery and truth?detection. While he rediscovered and modified well?known principles of induction, analysis and synthesis, and decision theory, he also made significant contributions to patterns of explanation, and with his ?principle of exclusion? was an ingenious innovator. This latter cornerstone of Holmes's methodology led him to an interesting modal theory of the ?improbable (...) possible? as a competitor to the famous doctrine of the ?impossible probable? put forward by Aristotle in de Arte Poetica. Holmes's scientific discipline was seasoned by warmth, understanding, and boldness. (shrink)

Socratic Method in the Euthyphro can be fruitfully analysed as a method of irony interpretation. Socrates' method – the irony of irony interpretation – is to pretend that Euthyphro is an ironist in order to transform him into a self-ironist. To be a self-ironist is to ironize one's knowledge of virtue in order to bring an intuitive and unarticulated awareness of virtue to mind. The exercise of the capacity for self-irony is then a mode of striving for the good.

An argument can be superficially valid and rhetorically effective even if what is plausibly meant, what is derived from what, and how it is derived is not at all clear. An example of such an argument is provided by Socrates’s famous refutation of Euthyphro’s second definition of holy, which is generally regarded as clearly valid and successful. This paper provides a stricter logical analysis than the ones in the literature. In particular, it is shown that the argument contains a syntactically (...) ambiguous expression, a passage that needs to be read charitably, and a previously unnoticed but crucial shift between two notions of unholy. Different analyses may be provided, depending on how these interpretation problems are solved. The conditions under which the refutation is valid and successful are far from obvious, and are here explicitly specified. (shrink)

THE aim of this paper is to explain a paradox in Plato's philosophy. On the one hand, Plato reduces virtue to knowledge; on the other, he rejects the possibility of knowledge or at least has serious doubts that it exists. I shall propose in this paper that the definition of virtue as knowledge is a logical outcome of Plato's denial of the particular aspect of knowledge as cognitive relation. This paper may also be considered as an attempt to resolve the (...) Hintikka‐Santas polemic about whether there is a difference in Plato's philosophy between the function of knowledge and its object. ([3], [6] pp. 1–71). The first part of this paper consists in a critical exposition of Plato's rejection of cognitive relation as a function of knowledge. The second part is devoted to an account of Plato's assumptions in this regard. In the third section of the paper I shall show how, on the basis of these assumptions, Plato reduces virtue to knowledge. And finally, in the last section of the essay, I shall compare my interpretation of this issue with other modern interpretations, especially those of Gerasimos Santas and Jaakko Hintikka. (shrink)

RésuméEn expliquant la relation entre hypothèses et images dans l'analogie de la ligne du livre Vl de laRépubliquede Platon, je m'attarde d'abordsur l'élucidation platonicienne de la nature des mathématiques telle que la conçoit le mathématicien lui-même. Je poursuis avec une critique des interprétations traditionnelles de cette relation, qui partent de l'assomption douteuse que les mathématiques s'occupent des Formes platoniciennes. Pour formuler mon point de vue sur cette relation, j'exploite la notion de «structure». Je montre comment les «hypothèses» comme principes de (...) preuve peuvent déterminer les structures des «images» par lesquelles les structures intelligibles correspondantes des objets mathématiques en viennent à être connues.
