Numerous informal logi- cians and argumentation theorists restrict their theorizing to what they call “real” arguments. But is there a clear distinction to be made between “real” and “non-real” arguments? Here I explore four possible accounts of the alleged distinction and argue that none can serve the theoretical uses to which the distinction is most often put. Résumé: Plusieurs logiciens construction formels et théoriciens de l’argument- ation limitent leur non de théories à ce qu’ils appellent des arguments « authentiques ». (...) Mais y-a- t’il une distinction claire entre des arguments« authentiques » et « inau- thentiques » ? Ici j’explore quatre descriptions possibles de cette préten- due distinction et je soutiens qu’- aucune ne répond aux besoins théori- ques auxquels elles sont censées ré- pondre. (shrink)

Despite a growing number of models argument for the logical possibility of changing the past there continues to be resistance to and confusion surrounding the possibility of changing the past. In this paper I shall attempt to mitigate the resistance and alleviate at least some of the confusion by distinguishing changing the past from what Richard Hanley calls ‘annulling’ the past and distinguishing both from what I shall call ‘otherwising’ the past.

The realist interpretations of quantum theory, proposed by de Broglie and by Bohm, are re-examined and their differences, especially concerning many-particle systems and the relativistic regime, are explored. The impact of the recently proposed experiments of Vigier et al. and of Ghose et al. on the debate about the interpretation of quantum mechanics is discussed. An indication of how de Broglie and Bohm would account for these experimental results is given.

The object of this paper is, as the title implies, to investigate the relation of Plato’s thought to natural science. More especially, it is intended to examine the widely held view that Plato’s influence, owing to the character of his beliefs, was necessarily and positively unfavourable to the development of natural science, as we know it at the present day.

I.T. Oakley claims that the cogency of invalid, but cogent, arguments is context independent. Robert Pargetter and John Bigelow claim that the apparent cogency of any cogent, but invalid, argument is to be explained by the existence of a corresponding valid argument. I argue that both claims are incorrect and provide my own account of the cogency of arguments.

David Hitchcock, in his recent “Informal Logic and the Concept of Argument”, defends a recursive definition of ‘argument.’ I present and discuss several problems that arise for his definition. I argue that refining Hitchcock’s definition in order to resolve these problems reveals a crucial, but minimally explicated, relation that was, at best, playing an obscured role in the original definition or, at worst, completely absent from the original definition.

Farmers in developed countries have established various tillage practices for crop production. These include plowing, disking, subsoiling, harrowing, field cultivating, rotary hoeing, and row-crop cultivating. But these conventional tillage practices necessitate the use of heavy equipment that often causes soil compaction, impairs soil physical conditions, and creates conditions leading to soil erosion. Many Western countries, studying their conventional tillage systems through the new perspective of sustainable approaches to agriculture, are developing new tillage practices, called conservation tillage, which limit tillage to (...) essential operations and prevent damage to soil. The majority of the small-scale farmers in developing countries use indigenous tillage systems. These are low-cost, locally adapted technologies that reflect considerable knowledge of sustainable agriculture. Ironically, the new conservation tillage systems currently being developed in the West have many characteristics of indigenous tillage systems. This paper compares conventional, conservation, and indigenous tillage practices, using examples from the United States and India, and concludes that, for sustainable food production, indigenous tillage practices in developing countries should continue to be used.

Obstetricians face difficult decisions when the interests of fetus and mother conflict. An example is the problem of choosing the delivery method when labour begins prematurely and the fetus is breech. Vaginal delivery involves risks for the breech fetus of brain damage or death caused by umbilical cord compression and head entrapment. Caesarean section might avoid these dangers but involves risks for the mother, including infection, haemorrhage and even death in a small percentage of cases. If a caesarean section is (...) performed the infant might die anyway, due to complications of prematurity. Thus, decisions about delivery method involve balancing the risks to mother and fetus. Uncertainty about the frequency of fetal injuries in vaginal breech deliveries adds to the difficulty of these decisions. (shrink)

Le philosophe canadien Charles Taylor est un des penseurs contemporains qui jouit d’une reconnaissance mondiale : il a initié et participé à plusieurs débats relatifs au libéralisme, au communautarisme et au multiculturalisme. Son œuvre est pluridimensionnelle puisque ses travaux portant, entre autres, sur la théorie de science, la théorie du langage, la théorie de l’action et de la personne, la théorie de la modernité.La pensée de Charles Taylor s’est élaborée non seulement en se nourrissant des traditions aussi bien phénoménologique qu’analytique, (...) mais, très concrètement, en prise directe avec les problèmes soulevés dans la société canadienne par la très grande diversité des immigrations. Sa pensée mérite d’autant plus à être méditée que les tentations de repli communautaire, si ce n’est de purification ethnique, semblent aujourd’hui croissantes. Les contributions – pour moitié en anglais – de ce colloque organisé à Budapest en 2012 en l’honneur et en présence de Charles Taylor invitent au contraire à interroger et à poursuivre son analyse des conditions qui permettraient l’avènement d’un monde véritablement pluriel.

According to the prevailing sentiment, changing the past is logically impossible. The prevailing sentiment is wrong. In this paper, I argue that the claim that changing the past entails a contradiction ultimately rests upon an empirical assumption, and so the conclusion that changing the past is logically impossible is to be resisted. I then present and discuss a model of time which drops the empirical assumption and coherently models changing the past. Finally, I defend the model, and changing the past, (...) against objections.

It is hardly necessary to recapitulate Rhys Roberts' cumulative and convincing proof that the treatise ‘On the Sublime’ was not written by Cassius Longinus, the tutor of Zenobia, but belongs to the early days of the Empire. Not the least convincing of the arguments for this date is the fact that the treatise is suggested by and put out as a substitute for the Περ ״ϒψоνς of Caecilius of Calacte, who according to Suidas taught rhetoric in Rome in the time (...) of Augustus. Now Caecilius was an intimate friend of Dionysius of Halicarnassus : they were both Atticists and fellow-workers in leading literary Romans back to the best models of Greek prose style. But Dionysius is no candidate for the authorship of the extant treatise, which is not one that he could have written. On the other hand he gives a plain indication by which to identify its writer, which Rhys Roberts mentioned but did not adopt. It is the object of this paper to put this identification seriously forward. (shrink)
