I examine Aristotle’s definition of scientific knowledge in Posterior Analytics 71b 9-12 and try to understand how it relates to the sophistical way of knowing and to "kata sumbebekos knowledge". I claim that scientific knowledge of p requires knowing p by its appropriate cause, and that this appropriate cause is a universal (katholou) in the restricted sense Aristotle proposes in 73b 26-27 ff., i.e., an attribute coextensive with the subject (an extensional feature) and predicated of the subject in itself (an (...) intensional feature). Kata sumbebekos knowledge, on the other hand, can occur even when the predicate of a conclusion is coextensive with its subject and is proved by a convertible meson which is not the most appropriate from an explanatory standpoint.

This paper attempts to clarify the nature and the importance of a third kind of sophistic argument that is not always found in the classification of those arguments in the secondary literature. An argument of the third kind not only is a valid one, but is also constituted of true propositions. What makes it a sophistic argument is the fact that it produces a false semblance of scientific explanation: its explanation seems to be appropriate to the explanandum without being so. (...) Evidence from this kind of argument comes from Sophistic Refutations 11, and Brison’s attempt to square the circle should be counted as one of its instances. (shrink)

The prologue of the Sophistici elenchi is as close an Aristotelian text gets to dealing with language as a subject matter in its own right, only in reverse. Language and its features bear consideration to the extent that they account for some major predicaments discursive reasoning is prone to, both as a separate and as a common endeavour. That being said, the linguistic pitfalls that trick us into thinking that whatever is the case for words and word-compounds is also the (...) case for the things and facts linguistic items stand for reveal as much about good linguistic habits and sound argumentation as they themselves are revealed by the principles and rules our argumentation goes by. In this connection, Aristotle resorted to a curious (or not so curious) analogy between words and counters which played a major role in explaining why language is such a powerful source of illusion and deception. As it happens, Aristotle accounting analogy is a case in point for showcasing the level of sophistication medieval Latin literature on fallacies achieved as early as the first half of the twelfth century. As a matter of fact, Western commentators managed to build compelling cases both in favour of and against the understanding that was to become and still is the standard story – which, of course, speaks volumes about their exegetical proficiency and technical expertise. On the one hand, trusting implicitly Boethius’ translation and well aware of his views on disputational hazards as opposed to computational reliability, they usually understood Aristotle’s comparison as if it was an analogy in name only. On the other hand, despite Boethius’ translation put them at a considerable disadvantage, Latin commentators were able to construe Aristotle’s analogy as bringing together two sets of symbolic variables (words and counters) that are neither entirely free nor entirely bound – which expose them to subtle but critical shifts in value and meaning.

The Holy Scriptures can be considered a specific kind of normative texts, whose use to assess practical moral cases requires interpretation. In the field of ethics, this interpretative problem results in the necessity of bridging the gap between the normative source – moral precepts – and the specific cases. In the history of the Church, this problem was the core of the so-called casuistry, namely the decision-making practice consisting in applying the Commandments and other principles of the Holy Scriptures to (...) specific cases or moral problems. By taking into account the sin of lying, this paper argues that casuistic texts reveal an extremely sophisticated interpretative method, grounded on “pragmatic” contextual and communicative considerations and argumentative structures that resemble the ones used in legal interpretation. These works show how the underspecified biblical text expressing an abstract norm was enriched pragmatically by completing it and modulating its meaning so that it could be used to draw a conclusion in a specific context on a specific case. The mutual interdependence between biblical interpretation, pragmatics, and argumentation sheds light on a much broader phenomenon, namely the pragmatic nature of argumentation. (shrink)

This paper addresses specific concerns that emerge as a consequence to the current educational reforms in the Philippines. These concerns are philosophical and pedagogical. The philosophical concern underscores the importance to situate philosophical thought within concrete historical conditions. In this way, philosophy does not only become a pure abstract enterprise, but an intellectual struggle at the service of historical novelties. I propose a philosophical paradigm that values collective practice at the service of truth. As new situations demand new interpretations and (...) contextualization, I shall also employ a philosophical discourse and practice not only contemporary to, but also one of the bests of our times: the philosophy of Alain Badiou. The pedagogical concern elucidates the political nature of education, which is what Critical Pedagogy argues essentially. This paradigm puts importance above all on the role critical knowledge and collective practice plays in the educational and socio-political arena. The critical pedagogy which I propose is not far from the emancipation politics also embedded in Badiouian Philosophy. Hence, there is a connection between the kind of philosophy I propose and the pedagogical paradigm I present as an alternative. From the philosophical and pedagogical arguments presented, I shall argue for the need to rescue education from the influence of neoliberalism. The resistance necessitates the movement of the collective through the agency of the teacher-militant. (shrink)

The phrase _secundum quid et simpliciter_ is the Latin expression translating and labelling the sophism described by Aristotle as connected with the use of some particular expression “absolutely or in a certain respect and not in its proper sense.” This paper presents an overview of the analysis of this fallacy in the history of dialectics, reconstructing the different explanations provided in the Aristotelian texts, the Latin and medieval dialectical tradition, and the modern logical approaches. The _secundum quid_ emerges as a (...) strategy that is based on the pragmatic dimension of arguments, and in particular the complex passage from an utterance (what is said) to its logical form (a proposition in an argument). The medieval and modern logical theories attempted to explain from different philosophical perspectives how the pragmatically enriched semantic representation can be achieved, justified, and most importantly manipulated. The different analyses of this fallacy bring to light various dimensions of the pragmatics of arguments, and the complex interdependence between context, meaning, and inferences. (shrink)

This paper discusses two issues that have challenged interpreters of Aristotle’s Sophistical Refutations : the criteria behind Aristotle’s classification of linguistic fallacies; the interpretation of the opening passage of SE 4. Although Aristotle never clarifies the principles underlying his classification, I contend that his list of six linguistic fallacies in SE is not arbitrary, but relies on a precise rationale which lies in his conception of λέξις as expressed mainly in Poetics 20. The disclosure of this rationale allows in turn (...) for the reconstruction of the “proof through συλλογισμός sketched in SE 4, which is supposed to prove that Aristotle’s list of linguistic fallacies is exhaustive: the proof is not a συλλογισμός in the sense of deductive argument, but a diairetic συλλογισμός a division.

The paper discusses the place and the status of fallacies in Arnauld and Nicole’s Port-Royal Logic, which seems to be the first book to introduce a radical change from the traditional Aristotelian account of fallacies. The most striking innovation is not in the definition of a fallacy but in the publication of a new list of fallacies, dropping some Aristotelian ones and adding more than ten new ones. The first part of the paper deals with the context of the book’s (...) publication. We then show the influence of Cartesian and Augustinian/Pascalian philosophy on the whole book, especially their common critical views about logic, dialectic and their traditional academic teaching. The third part of the paper discusses the two chapters on fallacies. It focuses on their place in the book and their relation with its general orientation, before turning to their content, closely connected with some major concerns of the time. (shrink)

The article examines Aristotle’s seminal discussion of the fallacy of begging the question, reconstructing its complex articulation within a variety of different, but related, contexts. I suggest that close analysis of Aristotle’s understanding of the fallacy should prompt critical reconsideration of the scope and articulation of the fallacy in modern discussions and usages, suggesting how begging the question should be distinguished from a number of only partially related argumentative faults.

In this paper I will attempt a unified analysis of the various examples of the fallacy of accident given by Aristotle in the Sophistical Refutations. In many cases the examples underdetermine the fallacy and it is not trivial to identify the fallacy committed. To make this identification we have to find some error common to all the examples and to show that this error would still be committed even if those other fallacies that the examples exemplify were not. Aristotle says (...) that there is only one solution “against the argument” as opposed to “against the man”, and it is this solution the paper attempts to find. It is a characteristic mark of my analysis that some arguments that we might normally be inclined to say are fallacious turn out to be valid and that some arguments that we would normally be inclined to say are valid turn out to be fallacious. This is (in part) because what we call validity in modern logic is not the same as the apodicticity that Aristotelian syllogisms require in order to be used in science. The fallacies of accident, uniquely among the fallacies, are failures of apodicticity rather than failures of, in particular, semantic entailment. This makes sense in a tensed and token-based logic such as Aristotle’s. I conclude that the closest analogue to the fallacy of accident that we can point to is a fallacy in modal logic, viz., the fallacy of necessity. (shrink)

When in classical formal logic the notions of deduction, valid inference and logical consequence are defined, causal language plays no role. The founder of western logic, Aristotle, identified ‘non-cause’, or ‘positing as cause what is not a cause’, as a logical fallacy. I argue that a systematic re-examination of Aristotle's analysis of NCF, and the related language of logical causality, in the Sophistical Refutations, Topics, Analytics and Rhetoric, helps us to understand his conception of. It reveals that Aristotle's syllogismhood is (...) non-monotonic, and thus narrower than classical validity as consisting in, or coextensive with, necessary truth-preservation. It also supports the conclusion that a syllogism is a form of relevant consequence: the premisses must be causes of the conclusion in the sense that they are not only sufficient but also necessary for the conclusion to follow. Close analysis of NCF also suggests that syllogistic relevance is not a semantic matter, but a syntactic.. (shrink)

Argumentation virtue theory is a new field in argumentation studies. As in the case of virtue ethics and virtue epistemology, the study of virtue argumentation draws its inspiration from the works of Aristotle. First, I discuss the specifics of the argumentational virtues and suggest that they have an instrumental nature, modeled on the relation between the Aristotelian intellectual virtue of ‘practical wisdom’ and the moral virtues. Then, inspired by Aristotle’s discussion of akrasia, I suggest that a theory of fallacy in (...) argumentation virtue theory can be built upon the concept of ‘incontinence’. (shrink)

From Aristotle’s Sophistical Refutations the following classifications are put forward and defended through extensive excerpts from the text. (AR-PFC) All sophistical refutations are exclusively either ‘apparent refutations’ or ‘proofs of false conclusions’. (AR-F) ‘Apparent refutations’ and ‘fallacies’ name the same thing. (ID-ED) All fallacies are exclusively either fallacies in dictione or fallacies extra dictionem . (ID-nAMB) Not all fallacies in dictione are due to ambiguity. (AMB-nID) Not all fallacies due to ambiguity are fallacies in dictione . (AMB&ID-ME) The set of (...) fallacies due to ambiguity and fallacies in dictione together comprise the set of arguments said to be “dependent on mere expression”. Being “dependent on mere expression” and “dependent on language” are not the same (instances of the latter form a proper subset of instances of the former). (nME-FACT) All arguments that are not against the expression are “against the fact.” (FACT-ED) All fallacious arguments against the fact are fallacies extra dictionem (it is unclear whether the converse is true). (MAN-ARG) The solutions of fallacious arguments are exclusively either “against the man” or “against the argument.” (10) (F-ARG) Each (type of) fallacy has a unique solution (namely, the opposite of whatever causes the fallacy), but each fallacious argument does not. However, each fallacious argument does have a unique solution against the argument, called the ‘true solution’ (in other words, what fallacy a fallacious argument commits is determined by how it is solved. However, if the solution is ‘against the man’ then this is not, properly speaking, the fallacy committed in the argument. It is only the ‘true solution’—the solution against the argument, of which there is always only one—that determines the fallacy actually committed). (shrink)

Modern logicians have sought to unlock the modal secrets of Aristotle's Syllogistic by assuming a version of essentialism and treating it as a primitive within the semantics. These attempts ultimately distort Aristotle's ontology. None of these approaches make full use of tests found throughout Aristotle's corpus and ancient Greek philosophy. I base a system on Aristotle's tests for things that can never combine (polarity) and things that can never separate (inseparability). The resulting system not only reproduces Aristotle's recorded results for (...) the apodictic syllogistic in the Prior Analytics but it also generates rather than assumes Aristotle's distinctions among 'necessary', 'essential' and 'accidental'. By developing a system around tests that are in Aristotle and basic to ancient Greek philosophy, the system is linked to a history of practices, providing a platform for future work on the origins of logic.

In Sophistical Refutations 8 Aristotle claims that every sophistical refutation depends on a false belief which is implicitly held by the victim of the fallacy and can normally be elicited from him as an explicit additional premiss. In this case the fallacious argument will be turned into a valid one, albeit with a false premiss. The paper discusses the nature of the FVP and tries to discover how it works when it tacitly causes the false appearance of a fallacious argument.

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.

A través del reconocimiento del principio de la distinción y su implicación ante-predicativa, las falacias extra-lingüísticas del secundum quid y del accidente propuestas por Aristóteles en los Sophistici Elenchi serán explicadas, probadas, analizadas y resueltas. De esta manera, se postula que las falacias que Aristóteles presenta en dicho libro tienen su raíz en una consideración falaz antepredicativa y no en el paralogismo, lo que abre una nueva forma de analizar las falacias aristotélicas. Con esto, se probará que el análisis de (...) las falacias como paralogismos es posterior, pues se mantendrá la tesis de que la falacia se genera en el nivel de distinción ontológica ante-predicativa y no en el nivel lingüístico del razonamiento. Se propondrá un modelo divisivo que aporta información al modelo inclusivo de la lógica tradicional, esto porque él nos permitirá dar cuenta del principio de la distinción. (shrink)

Refutaciones Sofísticas ha sido usualmente interpretado como un intento de clasificación de sofismas. Este acercamiento, sin embargo, corre el riesgo de oscurecer la dimensión de sus propias intenciones confrontativas. El presente trabajo se propone enfatizar la importancia de las Refutaciones Sofísticas como parte de un programa antierístico que tiene por objetivo prioritario la filosofía megárica, en las antípodas de Aristóteles en el terreno epistemológico. Bajo esta luz, la resolución de argumentos erísticos excede el estudio lógico así como también la denuncia (...) sobre sus efectos prácticos y se erige como parte de una discusión entre líneas de inspiración socrática sobre los alcances y fines de la dialéctica y la filosofía en general.
