The five participants in this dialogue critically discuss Zeno of Elea's paradox of Achilles and the tortoise. They consider a number of solutions to and restatements of the paradox, together with their philosophical implications. Among the issues investigated include the appearance-reality distinction, Aristotle's distinction between actual and potential infinity, the concept of a continuum, Cantor's continuum hypothesis and theory of transfinite ordinals, and, as a solution to Zeno's puzzle, the distinction between infinite and indeterminate or inexhaustible divisibility.

This is an exploration of what Locke and Whately said about the Argumentatum ad Hominem, especially in the context of what they said about the other ad arguments, and with a view to ascertaining whether what they said lends support to the understanding of this argument implicit in Johnstone's thesis that all valid philosophical arguments are ad hominem. It is concluded that this support is forthcoming insofar as Locke and Whately had in mind an argument concerned with principles.The essay ends (...) with a brief reformulation of Johnstone's generalization regarding philosophical arguments.

Written in an outstandingly clear and lively style, this 1969 book provokes its readers to rethink issues they may have regarded as long since settled.

Develops a logical analysis of dialogue in which two or more parties attempt to advance their own interests. It includes a classification of the major types of dialogues and a discussion of several important informal fallacies.

In Plato’s dialogues, the Phaedo, Laches, and Republic, Socrates warns his interlocutors about the dangers of misology. Misology is explained by analogy with misanthropy, not as the hatred of other human beings, but as the hatred of the logos or reasonable discourse. According to Socrates, misology arises when a person alternates between believing an argument to be correct, and then refuting it as false. If Socrates is right, then misanthropy is sometimes instilled when a person goes from trusting people to (...) learning that others sometimes betray our reliance and expectations, and finally not to placing any confidence whatsoever in other people, or, in the case of misology, in the correctness or trustworthiness of arguments. A cynical indifference to the soundness of arguments generally is sometimes associated with Socrates’ polemical targets, the Sophists, at least as Plato represents Socrates’ reaction to these itinerant teachers of rhetoric, public speaking and the fashioning of arguments suitable to any occasion. Socrates’ injunctions against misology are largely moral, pronouncing it ‘shameful’ and ‘very wicked’, and something that without further justification we must ‘guard against’, maintaining that we will be less excellent persons if we come to despise argument as lacking the potential of leading to the truth. I examine Socrates’ moral objections to misology which I show to be inconclusive. I consider instead the problem of logical coherence in the motivations supposedly underlying misology, and conclude that misology as Socrates intends the concept is an emotional reaction to argumentation on the part of persons who have not acquired the logical dialectical skills or will to sort out good from bad arguments. We cannot dismiss argument as directed toward the truth unless we have a strong reason for doing so, and any such argument must itself presuppose that at least some reasoning can be justified in discovering and justifying belief in interesting truths. The relevant passages from Socrates’ discussion of the soul’s immortality in the Phaedo are discussed in detail, and set in scholarly background against Socrates’ philosophy more generally, as represented by Plato’s dialogues. I conclude by offering a suggestive list of practical remedies to avoid the alienation from argument in dialectic with which Socrates is concerned. (shrink)

Never before has there been a greater need for deeper listening and more open communication to cope with the complex problems facing our organizations, businesses and societies. Renowned scientist David Bohm believed there was a better way for humanity to discover meaning and to achieve harmony. He identified creative dialogue, a sharing of assumptions and understanding, as a means by which the individual, and society as a whole, can learn more about themselves and others, and achieve a renewed sense of (...) purpose.

One in the series New Dialogues in Philosophy, edited by the author himself, Dale Jacquette presents a fictional dialogue over a three-day period on the ethical complexities of capital punishment. Jacquette moves his readers from outlining basic issues in matters of life and death, to questions of justice and compassion, with a concluding dialogue on the conditional and unconditional right to life. Jacquette's characters talk plainly and thoughtfully about the death penalty, and readers are left to determine for themselves how (...) best to think about the morality of putting people to death.

Among theorists of all kinds, those generally engaged at some level of their work in a dialectical enterprise, and certainly in argumentation theory, much argument concerns, is about or directed toward, other arguments. Arguments about arguments, meta-arguments, including all of the rational inferential underpinnings of argumentation theory, are in several ways and for several reasons worth distinguishing from arguments about things other than arguments, such as the causes of WWI or the periodicity of the tides.Maurice A. Finocchiaro in this new (...) book offers an interesting contribution to argumentation theory, and in particular to the study of meta-arguments about the logic and critical evaluation of arguments, in both a general sense as argumentation theory, and in specific applications. One of Finocchiaro’s preferred subjects of specific application of his approach to meta-argumentation theory is in understanding the fine details of Galileo’s arguments and meta-arguments, especially i.

David Bohm is considered one of the best physicists of all time. He also had a deep interest in human communication and creativity. Influential in both management and communication theory in what is known 'Bohm Dialogue', On Dialogue is both inspiring and pioneering. Bohm considers the origin and very meaning of dialogue, reflecting on what gets in the way of "true dialogue". He argues that dialogue, as a radical form of exploration that allows different views to be presented, leads us (...) beyond the impasse of conflict and argument to the forming of new views.

Dialogical logic is a game-theoretical approach to logic. Logic is studied with the help of certain games, which can be thought of as idealized argumentations. Two players, the Proponent, who puts forward the initial thesis and tries to defend it, and the Opponent, who tries to attack the Proponent’s thesis, alternately utter argumentative moves according to certain rules. For a long time the dialogical approach had been worked out only for classical and intuitionistic logic. The seven papers of this dissertation (...) show that this narrowness was uncalled for. The initial paper presents an overview and serves as an introduction to the other papers. Those papers are related by one central theme. As each of them presents dialogical formulations of a different non-classical logic, they show that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof. As such it is especially attractive to logical pluralists that reject the idea of “the single correct logic”. The collection contains treatments of free logic, modal logic, relevance logic, connexive logic, linear logic, and multi-valued logic. (shrink)
