Rigorous proof is supposed to guarantee that the premises invoked imply the conclusion reached, and the problem of rigor may be described as that of bringing together the perspectives of formal logic and mathematical practice on how this is to be achieved. This problem has recently raised a lot of discussion among philosophers of mathematics. We survey some possible solutions and argue that failure to understand its terms properly has led to misunderstandings in the literature.

After motivating a framework for evaluating top-down, middle-out, middle-in, and bottom-up ontology development strategies, we apply our framework to investigate whether infectious disease ontologies - specifically, the Virus Infectious Disease Ontology (VIDO) and the Coronavirus Infectious Disease Ontology (CIDO) - effectively promote semantic interoperability.

The traditional use of conventional media by businesses for audience targeting has shifted with the rise of influencer marketing, notably on platforms like TikTok, posing challenges in content adaptation and technological adaptation. Albert Bandura's Social Cognitive Theory examines factors shaping purchasing behavior, particularly relevant for young professionals. A quantitative correlational study focused on young professionals engaging with TikTok and influenced by Filipino TikTok creators, revealing education level as a key determinant of purchasing behavior. Extended TikTok engagement positively correlates with increased (...) purchasing likelihood. Filipino TikTok influencers significantly impact young professionals' purchasing decisions, emphasizing the need for tailored marketing strategies targeting this demographic. Recommendations were provided for effective influencer and digital marketing strategies targeting young professionals. (shrink)

The educators of the 21st century have a great task ahead. In today’s world, the educators are expected to have a great deal of professional and personal qualities, and extraordinary skills. This descriptive-correlational study aimed to determine perceptions of college students on a well-qualified educator. The study included 123 selected college students from different colleges in Central Luzon, Philippines using a convenience sampling technique. As data collection tool, a questionnaire prepared by the researcher team was used. Some of the findings (...) of the study include: (1) the respondents answered agree on the context of professional and personal qualities that a teacher should have; (2) while in terms of the skills exhibited by an educator, it got an answer to Very Satisfactory. We also found significant differences in professional qualities, learning and innovation skills and life and career skills when grouped according to the respondent’s profile. There was low-to-moderate evidence of the relationship that existed between the qualities and skills of an educator. The results further confirmed the relationship through regression analysis and found that communication skills affect the qualities of an educator. Based on the results, we discussed and recommended practical suggestions on professional, personal and skills improvements of an educator. (shrink)

O presente artigo se propõe definir o que é predicação em Aristóteles, como predicamos e qual o critério para determinar se uma predicação é verdadeira ou falsa. Nossas referências serão o livro Das Categorias, do capítulo 1 ao 5 e Da interpretação do capítulo 1 ao 6. Concluiremos que a teoria da predicação em Aristóteles afirma que definir algo é predicar e que o critério de verdade de uma proposição é a sua correspondência aos fatos.

This study delves into the feasibility of introducing a market in Barangay Tanagan, Calatagan, Batangas, with a primary focus on assessing its viability and potential impact on local economic development. Utilizing survey questionnaires and employing statistical analysis techniques, the research gathered data from a carefully selected sample of 366 residents out of the total population of 4,224. The study evaluates both the potential benefits and challenges associated with establishing the proposed market. Findings, subjected to thorough analysis through methods such as (...) frequency counts and weighted mean calculations, provide valuable insights into discernible patterns, emerging trends, and relevant correlations. This analytical approach contributes to a pragmatic perspective that informs and guides future studies in the field. The study reveals an interest among respondents in the establishment of public markets in their vicinity, recognizing its potential to bolster the barangay and attract diverse opportunities. The anticipated positive impact extends to fostering economic growth and enhancing local commerce in Barangay Tanagan. Consequently, based on these compelling findings, the researchers advocate for a proposal outlining the establishment of a public market in Barangay Tanagan as a means of addressing the identified needs and aspirations of the community.

This article argues that Rousseau's endorsement of male domination and his illiberal views of rape, punishment and the education of women have been seriously underestimated by twentieth century commentators who tend to produce expoisitions of his work that evade, ignore or marginalise this 'darker side' of his educational philosophy.

This paper will annoy modern logicians who follow Bertrand Russell in taking pleasure in denigrating Aristotle for [allegedly] being ignorant of relational propositions. To be sure this paper does not clear Aristotle of the charge. On the contrary, it shows that such ignorance, which seems unforgivable in the current century, still dominated the thinking of one of the greatest modern logicians as late as 1831. Today it is difficult to accept the proposition that Aristotle was blind to the fact that, (...) for example, incommensurability is a relation and not a property: that the proposition “In every square, the diagonals are incommensurable with the sides” is relational and not categorical. This paper asks the reader to do something more difficult: to accept the proposition that as late as 1831 De Morgan was blind to the same fact. This paper shows conclusively that in 1831, De Morgan was still in the grips of the allegedly Aristotelian paradigm. (shrink)

The world of entrepreneurship has historically been linked with taking risks and the potential for significant rewards. However, there persists a notable gender imbalance in the entrepreneurial landscape, wherein women entrepreneurs remain a minority. Women navigating the entrepreneurial path encounter distinct challenges, setting their experiences apart from their male counterparts. In Balayan, Batangas, despite strides towards gender equality, women entrepreneurs continue to face challenges in the entrepreneurial landscape. This qualitative study delves into the experiences of 10 successful female entrepreneurs who (...) met specific criteria. Accordingly, semi-structured interviews are conducted, exploring various aspects of participants' experiences and revealing their motivations, achievements, challenges, and strategies. Thematic analysis reveals the connection between familial, community-driven, and personal motivations that drive these entrepreneurs forward. Despite facing obstacles such as financial constraints and gender biases, they prioritize financial gains and personal growth. With resilience, innovation, and dedication, these women overcome challenges and achieve success, utilizing support networks and online marketing strategies to their advantage. Recommendations include empowering women in entrepreneurship, strengthening support networks, introducing tailored financial literacy programs, and advocating against gender biases. Implement skill development initiatives and provide specialized education in online marketing. Engage in policy advocacy, celebrate success stories, and continuously research challenges and successes. Foster collaborative partnerships between businesses, educational institutions, and communities, and advocate for increased funding opportunities for sustainable growth. This research emphasizes the strength and capabilities of women entrepreneurs in Balayan, Batangas, affirming that "pink doesn't mean weak.". (shrink)

This paper offers a new interpretation of Aristotle’s identification, in De Anima 2.5, of αἴσθησις with an ἀλλοίωσίς τις that is not ‘a kind of destruction of something by its contrary’. Drawing on a passage from Metaphysics Iota 5, it argues that when so described, what is referred to as an ἀλλοίωσίς τις is not a uniquely perceptual alteration.

In De Anima II 5, 417a21-b16, Aristotle makes a number of distinctions between types of transitions, affections, and alterations. The objective of this paper is to sort out the relationships between these distinctions by means of determining which of the distinguished types of change can be coextensive and which cannot, and which can overlap and which cannot. From the results of this analysis, an interpretation of 417a21-b16 is then constructed that differs from previous interpretations in certain important respects, chief among (...) which is its characterization of transitions from first potentiality to first actuality, e.g., learning, not as `ordinary', but rather as acquisitions of natural dispositions or faculties.

In the first two chapters of his 1925 book Les cadres sociaux de la mémoire (The Social Frameworks of Memory), the French sociologist Maurice Halbwachs (1877-1945) develops a sustained comparison between remembering and dreaming. Engaging in detail with large bodies of contemporary research in psychology, physiology, philosophy, and linguistics, he aims to combat what he calls the ‘surprising’ tendency of ‘psychological treatises that deal with memory’ to treat each of us as ‘an isolated being’ (1925/ 1994, vi) 1. In the (...) course of making a case that memory is deeply situated and social, Halbwachs offers a subtle and challenging treatment of dreams. (shrink)

This paper is concerned with the background to Lacan’s Seminar I, chapter xx on Augustine’s De magistro, its manuscript sources, editions and structure. The discussion of Augustine’s treatise was suggested to Lacan by Louis Beirnaert but he seems not to have known the text. We argue that there are reasons to think the suggestion came from his Jesuit confrere Paul Henry, the learned co-editor of the Enneads, who was helping to organise an international congress in Paris that year on Augustine. (...) Although the history of the discussion of ‘signs’ goes back to Aristotle, the only attempt to bring signification into a theory of language, prior to Augustine, is found in a passage in Plotinus which Henry had discussed some years earlier. The Latin text of De magistro they used was, unfortunately, badly corrupted and this contributed to a mistaken understanding of its structure. Nevertheless, Lacan found some important parallels between Augustine’s view on teaching and the complexity of understanding and his own teaching and psychoanalysis. (shrink)

Dans La Paléontologie : distancer le temps, John Huss examine les défis de la compréhension des échelles de temps géologiques en paléontologie. Les profondeurs du temps, comparables aux vastes distances spatiales, nécessitent des heuristiques uniques pour être conceptualisées. Huss explore la "spatialisation du temps", où les fossiles et les strates géologiques servent d'archives physiques de processus s'étendant sur des millions d'années. Cette approche permet aux paléontologues de reconstruire l'histoire de la Terre et de comprendre les changements évolutifs. -/- L'article (...) aborde comment les archives fossiles et la biologie moléculaire offrent des chronologies parfois complémentaires, mais aussi parfois contradictoires, des événements évolutifs, incitant à des progrès méthodologiques constants. Huss traite également des difficultés épistémologiques liées à l'étude de l'histoire profonde, en particulier du fait de la nature fragmentaire des archives géologiques. Il critique la métaphore traditionnelle de l'histoire de la Terre comme un "livre", suggérant que les couches vides de roches sédimentaires reflètent non seulement des lacunes dans les archives fossiles, mais aussi des changements systémiques dans l'environnement terrestre. Cette perspective met en lumière les méthodes intégratives complexes nécessaires pour reconstruire le passé ancien de la planète. (shrink)

This essay will examine the role of cultural memory in an age of global interconnection. It will discuss how the traditional idea of culture is threatened by the “culture industry,” information technology and the media. In the West, there seems to be a loss of culture’s function as an engine of change and reform. But throughout the history of South East Asia (and especially in Indonesia) one sees a both a process of appropriation of ideas from the outside, and at (...) the same time, the maintenance of a deeper cultural identity that is resistant to complete control. It is an unconscious memory – or a cultural reflex – present within the languages and stories and rationalities. I will explain this with reading of Michel de Certeau. And I will show how the Wayang story of the “Death of Semar” is emblematic of this idea. The awareness of these old processes of appropriation and resistance are extremely important in our age of global networks of power that attempt to impose, various religious, political, financial and legal structures.

Down through the ages, logic has adopted many strange and awkward technical terms: assertoric, prove, proof, model, constant, variable, particular, major, minor, and so on. But truth-value is a not a typical example. Every proposition, even if false, no matter how worthless, has a truth-value:even “one plus two equals four” and “one is not one”. In fact, every two false propositions have the same truth-value—no matter how different they might be, even if one is self-contradictory and one is consistent. It (...) is not such a big surprise that every true proposition, no matter how worthless, has a truth-value. Every proposition, whether valuable or worthless, has a truth-value.But it is a little strange that every two true propositions, no matter how different they might be, have the same truth-value. The Pythagorean Theorem has the same truth-value as the proposition that one is one. It is a stretch to think of truth-values as values in any of the normal senses of the word ‘value’. (shrink)

At De Anima II 5, 417b17, Aristotle says, ‘The first transition (πρώτη μεταβολή) in that which can perceive is brought about by the parent, and when it is born it already has [the faculty of] sense-perception in the same way as it has knowledge. Actual sense-perception is so spoken of in the same way as contemplation.’ The purpose of this paper is to determine the nature of first transitions.

Cette communication explorera la nature deleuzienne de l'ontologie présupposée par Foucault dans ses cours Sécurité, Territoire, Population et Naissance de la Biopolitique. L'objectif sera d'identifier certaines formules de Foucault qui font écho à un concept clé de Différence et Répétition: l'individuation comme intégration d'une multiplicité. Dans ces textes se trouveront pas mal d'éléments de l'ontologie deleuzienne: par exemple, le couple différentiation / différenciation; l'anti-essentialisme; et le champ différentiel, pré-individuel, problématique, ou virtuel d'où émergent, par l'auto-organisation, des individus actuels. Mais, on (...) verra aussi des difficultés conceptuelles, surtout dans sa notion de "possibilité," que subit Foucault dans quelques-unes de ses réflexions méthodologiques, difficultés qui émergent pour lui en faisant ses propres analyses de "la mise en intelligibilité en histoire" pendant qu'il présuppose l'ontologie deleuzienne.

Morality seems important, in the sense that there are practical reasons — at least for most of us, most of the time — to be moral. A central theoretical motivation for consequentialism is that it appears clear that there are practical reasons to promote good outcomes, but mysterious why we should care about non-consequentialist moral considerations or how they could be genuine reasons to act. In this paper we argue that this theoretical motivation is mistaken, and that because many arguments (...) for consequentialism rely upon it, the mistake substantially weakens the overall case for consequentialism. We argue that there is indeed a theoretical connection between good states and reasons to act, because good states are those it is fitting to desire and there is a conceptual connection between the fittingness of a motive and reasons to perform the acts it motivates. But while some of our motives are directed at states, others are directed at acts themselves. We contend that just as the fittingness of desires for states generates reasons to promote the good, the fittingness of these act-directed motives generates reasons to do other things. Moreover, we argue that an act’s moral status consists in the fittingness of act-directed feelings of obligation to perform or avoid performing it, so the connection between fitting motives and reasons to act explains reasons to be moral whether or not morality directs us to promote the good. This, we contend, de-mystifies how there could be non-consequentialist reasons that are both moral and practical. (shrink)

RÉSUMÉ : Dans son récent recueil d’articles Language, Truth and History, Donald Davidson semble pencher en faveur d’une philosophie du langage mettant l’accent sur la notion de l’intention communicative du sujet parlant; en quoi il se rapproche du point de vue de Paul Grice. Si cela est juste, la pensée de Davidson se serait dégagée de l’approche sémantique formelle qu’il soutenait dans ses Inquiries into Truth and Interpretation. Dans cet article, je soutiens que, bien qu’il y ait beaucoup de similitudes (...) entre ces deux penseurs, Davidson n’a pas abandonné ses précédentes vues sur le langage. (shrink)

The present dissertation presents an examination of the Carrollian logic through the reconstruction of its syllogistic theory. Lewis Carroll was one of the main responsible for the dissemination of logic during the nineteenth century, but most of his logical writings remained unknown until a posthumous publication of 1977. The reconstruction of the Carrollian syllogistic theory was based on the comparison of the two books on author's logic, "The Game of Logic" and "Symbolic Logic". The analysis of the Carrollian syllogistics starts (...) from a study of the historical context of development of the logic and the developments of syllogistics previous to the contribution of the author. Situated in the historical period of algebraical logic, Carrollian syllogistics is characterized as a conservative extension of the Aristotelian syllogistics, the main innovation is the use of negative terms and the introduction of a diagrammatic method suitable for the representation of negative terms. The diagrammatic method of the Carrollian syllogistics presents advances in relation to the methods of Euler and Venn. The use of negative terms also requires a redefinition of the notion of syllogism, simplifying and expanding the amount of arguments amenable to logical treatment. Carroll does not use four, but only three categorical propositions in his syllogistic, with interpretation of existential presuppositions congruent with a syntactic-existential reading. Carrollian syllogistics uses some techniques found in the work of algebraists of logic and also made the same confusions between notions of "class" and "member" that were common in the period. Convinced of the social utility of logic and dedicated to popularize it, Carroll priorized a creation of new didactics for the teaching of logic in his works, where he can include his diagrammatic method of solving syllogisms. Carroll made only scant considerations of his conception of logic. Based on the small considerations found throughout the study and on the constant claim of the social utility of logic, it is suggested that Carroll is close to the so-called pragmatic position, which considers a logic as an instrument of regulation of discourse.

ABSTRACT. This essay addresses the interpretation of Descartes’ understanding of the mind-body relationship as a substantial union in light of a statement he makes in the Passions de l’âme regarding the role of the blood and vital heat. Here, it seems Descartes cites these corporeal properties as the essential dispositions responsible for accommodating the soul into the human fetus. I argue that this statement should be read in the context of certain medical texts with which Descartes was familiar, namely those (...) of Jean Fernel and William Harvey. Reviewing Fernel’s comments on substantial union, one finds that the soul joins the body on the basis of a celestial spirit that not only bears the vital heat, it also directs the generation of the body. Similar to Harvey, Descartes locates these properties in the blood itself, although, in contrast to Harvey, Descartes reduces these processes to matter and motion. Finally, I highlight the role this heat plays in Descartes’ embryological writing, contrasting it with that of Fernel. I conclude that although Descartes makes various comments supporting a reading of the mind-body relation as a substantial union, his physiological writings on generation and his idea of ‘life’ contradict this interpretation. -/- .

Once Socrates has thought something, he comes to acquire an item such that he is then able to think such thoughts again when he wants, and he can, all other things being equal, do this with more ease than he could before. This item that he comes to acquire medieval philosophers called a cognitive habit which most medieval philosophers maintained was a new quality added to Socrates' intellect. However, some disagreed. In this paper, I will examine an interesting alternative theory (...) put forward by Durand of Saint-Pourçain and Prosper de Reggio Emilia about the location of cognitive habits. On their view, cognitive habits are not to be located in the intellect but in something on the side of the body or sensitive soul. (shrink)

Dilip Ninan has raised a puzzle for centered world accounts of de re attitude reports extended to accommodate what he calls “counterfactual attitudes.” As a solution, Ninan introduces multiple centers to the standard centered world framework, resulting in a more robust semantics for de re attitude reports. However, while the so-called multi-centered world proposal solves Ninan’s counterfactual puzzle, this additional machinery is not without problems. In Section 1, I present the centered world account of attitude reports, followed by the extension (...) to counterfactual attitudes which Ninan targets with his puzzle. In Section 2, I pose the counterfactual puzzle and present Ninan’s multi-centered world solution, emphasizing similarities and differences between multi-centered and centered world accounts of attitude reports. In Section 3, I argue the counterfactual attitude wishing falls under the purview of the multi-centered proposal, but that the proposal generates false predictions for wish reports concerning unsatisfiable content. I canvass responses, ultimately concluding Ninan’s proposal requires substantial revisions. (shrink)

A new reprogenetic technology, mitochondrial replacement, is making its appearance and, unsurprisingly given its promise to wash off our earthly stains --or at least the scourges of sexual reproduction--, John Harris finds only reasons to celebrate this new scientific feat.1 In fact, he finds mitochondrial replacement techniques (MRTs) so “unreservedly welcome” that he believes those who reject them suffer from “a large degree of desperation and not a little callousness.”2 Believing myself to be neither desperate nor callous, but finding (...) myself also no closer at all – not even after reading his article—to following Harris in welcoming these technologies wholeheartedly, it seems appropriate to respond.

Prime Matter Pluralism (PMP) states that while the prime matter of all terrestrial bodies is the same, there is a unique prime matter for each celestial body. Prime matters are distinct in virtue of being in potentiality to different forms. Steven Baldner argues that although Thomas Aquinas endorsed PMP in Summa theologiae I, he ultimately rejected it in his De caelo commentary and De substantiis separatis. Besides exegetical evidence for this claim, Baldner presents a philosophical objection to PMP: according to (...) PMP, distinct prime matters are restricted in their respective potentialities; such restriction requires form, however; therefore, prime matter is not pure potentiality. Since prime matter is pure potentiality, PMP is false. Pace Baldner, I argue that Aquinas endorses PMP as heartily in the later works as in STh I. Moreover, he resisted substantially the same objection to PMP as Baldner’s several times. In particular, Aquinas repeatedly rejected the claim that the restriction of prime matter’s potentiality requires form. In that case, when Aquinas calls prime matter “pure potentiality,” he means that it is formless of itself, not that it is in potentiality to any form whatsoever. (shrink)

This self-contained lecture examines uses and misuses of the adverb conversely with special attention to logic and logic-related fields. Sometimes adding conversely after a conjunction such as and signals redundantly that a converse of what preceded will follow. -/- (1) Tarski read Church and, conversely, Church read Tarski. -/- In such cases, conversely serves as an extrapropositional constituent of the sentence in which it occurs: deleting conversely doesn’t change the proposition expressed. Nevertheless it does introduce new implicatures: a speaker would (...) implicate belief that the second sentence expresses a converse of what the first expresses. Perhaps because such usage is familiar, the word conversely can be used as “sentential pronoun”—or prosentence—representing a sentence expressing a converse of what the preceding sentence expresses. -/- (2) Tarski read Church and conversely. -/- This would be understood as expressing the proposition expressed by (1). Prosentential usage introduces ambiguity when the initial proposition has more than one converse. Confusion can occur if the initial proposition has non-equivalent converses. -/- Every proposition that is the negation of a false proposition is true and conversely. -/- One sense implies that every proposition that is the negation of a true proposition is false, which is true of course. But another sense, probably more likely, implies that every proposition that is true is the negation of a false proposition, which is false: the proposition that one precedes two is not a negation and thus is not the negation of a false proposition. The above also applies to synonyms of conversely such as vice versa. Although prosentence has no synonym, extrapropositional constituents are sometimes called redundant rhetoric, filler, or expletive. Authors discussed include Aristotle, Boole, De Morgan, Peirce, Frege, Russell, Tarski, and Church. END OF PUBLISHED ABSTRACT -/- See also: Corcoran, John. 2015. Converses, inner and outer. 2015.

Some attention has also been devoted to a particular kind of judgment or a particular form of the intellect’s second operation, sometimes named separatio by Thomas. Important editions of questions 5 and 6 of Thomas’s commentary on the De Trinitate of Boethius in 1948 and 1955 and the groundbreaking study by L. B. Geiger in 1947, all have set the stage for further emphasis on this distinctive type of intellectual operation when it comes to one’s discovery of being, or better, (...) of that notion of being that can serve as subject of a science of being as being rather than a science of being as material or as quantified. While this new development has remained largely unnoticed in certain regions of Thomistic scholarship for a number of years, it has been pursued in depth by other writers. At the same time, investigation of the same nicely dovetails with the renewed emphasis on existence and on judgment as the process required to discover being as existing to which we have referred above. For as will be seen below, at least one passage in Thomas’s commentary reinforces the contention that one must pass beyond simple apprehension to the mind’s second operation or to judgment if one is to grasp being explicitly as existing. This particular point, however, is not our primary concern here. (shrink)

John Corcoran and George Boger. Aristotelian logic and Euclidean geometry. Bulletin of Symbolic Logic. 20 (2014) 131. -/- By an Aristotelian logic we mean any system of direct and indirect deductions, chains of reasoning linking conclusions to premises—complete syllogisms, to use Aristotle’s phrase—1) intended to show that their conclusions follow logically from their respective premises and 2) resembling those in Aristotle’s Prior Analytics. Such systems presuppose existence of cases where it is not obvious that the conclusion follows from the (...) premises: there must be something deductions can show. Corcoran calls a proposition that follows from given premises a hidden consequence of those premises if it is not obvious that the proposition follows from those premises. By a Euclidean geometry we mean an extended discourse beginning with basic premises—axioms, postulates, definitions—1) treating a universe of geometrical figures and 2) resembling Euclid’s Elements. There were Euclidean geometries before Euclid (fl. 300 BCE), even before Aristotle (384–322 BCE). Bochenski, Lukasiewicz, Patzig and others never new this or if they did they found it inconvenient to mention. Euclid shows no awareness of Aristotle. It is obvious today—as it should have been obvious in Euclid’s time, if anyone knew both—that Aristotle’s logic was insufficient for Euclid’s geometry: few if any geometrical theorems can be deduced from Euclid’s premises by means of Aristotle’s deductions. Aristotle’s writings don’t say whether his logic is sufficient for Euclidean geometry. But, there is not even one fully-presented example. However, Aristotle’s writings do make clear that he endorsed the goal of a sufficient system. Nevertheless, incredible as this is today, many logicians after Aristotle claimed that Aristotelian logics are sufficient for Euclidean geometries. This paper reviews and analyses such claims by Mill, Boole, De Morgan, Russell, Poincaré, and others. It also examines early contrary statements by Hintikka, Mueller, Smith, and others. Special attention is given to the argumentations pro or con and especially to their logical, epistemic, and ontological presuppositions. What methodology is necessary or sufficient to show that a given logic is adequate or inadequate to serve as the underlying logi of a given science. (shrink)

For example, Tarski’s expression ‘materially adequate’ was misinterpreted in at least one article and it was misused in another where ‘materially correct’ should have been used. The discussion provides an opportunity to bring more flaws to light. -/- Acknowledgements: Each of these entries was presented at meetings of The Buffalo Logic Dictionary Project sponsored by The Buffalo Logic Colloquium. The members of the colloquium read drafts before the meetings and were generous with corrections, objections, and suggestions. Usually one 90-minute meeting was devoted to one entry although in some cases, for example, “axiomatic method”, took more than one meeting. Moreover, about half of the entries are rewrites of similarly named entries in the 1995 first edition. Besides the help received from people in Buffalo, help from elsewhere was received by email.

JOHN CORCORAN AND WAGNER SANZ, Disbelief Logic Complements Belief Logic. Philosophy, University at Buffalo, Buffalo, NY 14260-4150 USA E-mail: [email protected] Filosofia, Universidade Federal de Goiás, Goiás, GO 74001-970 Brazil E-mail: [email protected] -/- Consider two doxastic states belief and disbelief. Belief is taking a proposition to be true and disbelief taking it to be false. Judging also dichotomizes: accepting a proposition results in belief and rejecting in disbelief. Stating follows suit: asserting a proposition conveys belief and denying conveys disbelief. Traditional (...) logic implicitly focused on logical relations and processes needed in expanding and organizing systems of beliefs. Deducing a conclusion from beliefs results in belief of the conclusion. Deduction presupposes consequence: one proposition is a consequence of a set of a propositions if the latter logically implies the former. The role of consequence depends on its being truth-preserving: every consequence of a set of truths is true. This paper, which builds on previous work by the second author, explores roles of logic in expanding and organizing systems of disbeliefs. Aducing a conclusion from disbeliefs results in disbelief of the conclusion. Aduction presupposes contrequence: one proposition is a contrequence of a set of propositions if the set of negations or contradictory opposites of the latter logically implies that of the former. The role of contrequence depends on its being falsity-preserving: every contrequence of a set of falsehoods is false. A system of aductions that includes, for every contrequence of a given set, an aduction of the contrequence from the set is said to be complete. Historical and philosophical discussion is illustrated and enriched by presenting complete systems of aductions constructed by the second author. One such, a natural aduction system for Aristotelian categorical propositions, is based on a natural deduction system attributed to Aristotle by the first author and others. ADDED NOTE: Wagner Sanz reconstructed Aristotle’s logic the way it would have been had Aristole focused on constructing “anti-sciences” instead of sciences: more generally, on systems of disbeliefs.

This paper is written on the occasion of the celebration of the gift of femininity. In this paper, I argue philosophically, as to what may be taken as a framework for what it means to be a female. While I am aware of the various attendant positions and orientations that are wont to accompany such a discussion, I maintain that a female is essentially, a human being with certain biological configurations, and other cultural descriptions. While this definition may be reductionist (...) at first approximation, the fact that the female is a human being means that the female is, in the words of Battista Mondin, a bundle of possibilities that can neither be understood in entirety, or reduced to a definite range. -/- Ce papier est écrit à l'occasion de la célébration du don de la féminité. Dans cet article, je discute philosophiquement de ce qui peut être considéré comme un cadre pour ce que signifie être une femme. Bien que je sois conscient des différentes positions et orientations qui accompagnent habituellement une telle discussion, je maintiens qu'une femme est essentiellement un être humain avec certaines configurations biologiques et d'autres descriptions culturelles. Bien que cette définition puisse être réductionniste en première approximation, le fait que la femme soit un être humain signifie que la femme est, selon les mots de Battista Mondin, un faisceau de possibilités qui ne peuvent ni être comprises dans leur intégralité, ni réduites à une gamme définie.

Thirteen meanings of 'implication' are described and compared. Among them are relations that have been called: logical implication, material implication,deductive implication, formal implication, enthymemic implication, and factual implication. In a given context, implication is the homogeneous two-place relation expressed by the relation verb 'implies'. For heuristic and expository reasons this article skirts many crucial issues including use-mention, the nature of the entities that imply and are implied, and the processes by which knowledge of these relations are achieved. This paper is (...) better thought of as an early stage of a dialogue than as a definitive treatise. (shrink)

Aristotle said that induction (epagōgē) is a proceeding from particulars to a universal, and the definition has been conventional ever since. But there is an ambiguity here. Induction in the Scholastic and the (so-called) Humean tradition has presumed that Aristotle meant going from particular statements to universal statements. But the alternate view, namely that Aristotle meant going from particular things to universal ideas, prevailed all through antiquity and then again from the time of Francis Bacon until the mid-nineteenth century. Recent (...) scholarship is so steeped in the first-mentioned tradition that we have virtually forgotten the other. In this essay McCaskey seeks to recover that alternate tradition, a tradition whose leading theoreticians were William Whewell, Francis Bacon, Socrates, and in fact Aristotle himself. The examination is both historical and philosophical. The first part of the essay fills out the history. The latter part examines the most mature of the philosophies in the Socratic tradition, specifically Bacon’s and Whewell’s. After tracing out this tradition, McCaskey shows how this alternate view of induction is indeed employed in science, as exemplified by several instances taken from actual scientific practice. In this manner, McCaskey proposes to us that the Humean problem of induction is merely an artifact of a bad conception of induction and that a return to the Socratic conception might be warranted.

Dans la philosophie contemporaine, la mémoire n’est plus un instrument qui apprend des évènements de manière passive. Ici, on parlera de la mémoire qu’une personne possède quand elle se souvient de sa propre vie ou d’un moment spécifique. Ce concept, un des plus anciens de la psychologie cognitive, s’appelle mémoire autobiographique. Grâce à cette pertinente interprétation d’un concept plus vivant de mémoire dans la science, la littérature et la philosophie de notre temps, on se demandera si, à travers son activité, (...) elle est dépendante d’un concept d’une temporalité linéaire ou si en fait sa vivacité lui permet de créer un temps propre. Quelques auteurs ont essayé de répondre à ce problème-là et ici on traitera de trois: Henri Bergson, Bertrand Russell et John Campbell, ce dernier étant un philosophe contemporain, en essayant d’établir les liens parmi les trois, avec pour but la mise de lumière des questions et des réponses qui ont survécu la mort des deux premiers auteurs mentionnés. À travers cette recherche, on se rendra compte que si le concept de mémoire était auparavant plus spécifiquement étudié toujours en connexion avec le concept d’image, dans la tradition analytique elle de plus en plus est mise à coté de la notion moderne d’identité personnelle. Toutefois, ce qui reste commun est l’effort de penser le souvenir au delà de la vie pratique; notamment en tant qu’une faculté psychique qui oriente tous nos choix et notre appréhension du monde et qui toujours semble échapper la dualité schématique entre circularité et linéarité temporelle, déjà mise en question dans les années 1990.

Part 1 of this exchange consists in a critique by Smith of Searle’s The Construction of Social Reality focusing on Searle’s use of the formula ‘X counts as Y in context C’. Smith argues that this formula works well for social objects such as dollar bills and presidents where the corresponding X terms (pieces of paper, human beings) are easy to identify. In cases such as debts and prices and money in a banks computers, however, the formula fails, because these (...) are cases of what he calls ‘free-standing Y terms’, since there is here no X which can count as the corresponding Y. In his response in Part 2, Searle argues that Smith’s critique rests on three misunderstandings: 1. in wrongly presupposing that Searle is trying to analyze the nature of what he calls “social objects”, rather than of social facts; 2. in thinking that the counts as formula is intended as a definition, rather than as a mere mnemonic; and 3. in neglecting the naturalism of Searle’s account.
