Ian Rumfitt (2000) developed a bilateralist account of logic in which the meaning of the connectives is given by conditions on asserted and rejected sentences. An additional set of inference rules, the coordination principles, determines the interaction of assertion and rejection. Fernando Ferreira (2008) found this account defective, as Rumfitt must state the coordination principles for arbitrary complex sentences. Rumfitt (2008) has a reply, but we argue that the problem runs deeper than he acknowledges and is in fact related to (...) the challenge of establishing proof-theoretic harmony. We motivate a distinctively bilateral criterion for harmony and show how the bilateralist can meet it. This also resolves Ferreira's complaint. (shrink)

El presente trabajo es un ensayo sobre lo que, en los últimos años, se ha empezado a llamar "lógica filosófica". La lógica filosófica se origina como consecuencia del progresivo rigor formal de la lógica tradicional. Este rigor ha conducido, en contra de lo que se esperaba, a problemas de significado filosófico fundamental y de profundidad abismal. Son muchos los problemas que interesan a la lógica filosófica, pero, en opinión del autor, el más importante apenas ha sido abordado. Este problema es (...) la relación entre la lógica y la razón. La tradición siempre ha considerado la lógica como una disciplina preeminentemente racional, que se constituye sobre estructuras fundamentales del pensamiento racional. Ahora bien, si se intenta saber cuáles son estas estructuras, se encuentra un grave problema: en los últimos años han proliferado nuevos sistemas de lógica, algunos de los cuales parecen no tener ninguna relación entre sí y con la lógica clásica. Esto da la impresión de que no tiene mucho sentido hablar de "razón humana", es decir, de una facultad que funciona mediante principios necesarios y universales organizados en un sistema unitario. La única manera de abordar este problema es comenzar con un análisis de los sistemas lógicos que difieren del modelo clásico (como, por ejemplo, las lógicas polivalentes y paraconsistentes). A estos sistemas el autor los denomina "lógicas heterodoxas". Una vez analizado el significado y las características de estas lógicas, es posible ver si realmente expresan el hecho de que la razón no puede ser concebida como un sistema de principios o si esta creencia es sólo una consecuencia de un enfoque superficial. La opinión del autor es que, a pesar de la multiplicidad de sistemas lógicos heterodoxos, es posible encontrar un criterio de unidad en el cumplimiento común de ciertas condiciones necesarias de logicidad y la posesión común de algunas condiciones suficientes. La razón no funciona, por supuesto, como creían los clásicos, pero su funcionamiento está determinado por un complejo invariable de principios necesarios y universales. Este funcionamiento es más flexible que el concebido por la lógica tradicional; la razón humana puede prescindir de algunos principios clásicos, pero no de todos, y, por el contrario, puede encontrar nuevos principios basados en evidencias que no habían sido previamente analizadas lógicamente. Pero en ambos casos, siempre presupone un complejo invariable de principios. (shrink)

In a world of ever growing specialization, the idea of a unity of science is commonly discarded, but cooperative work involving cross-disciplinary points of view is encouraged. The aim of this paper is to show with some textual support that Charles S. Peirce not only identified this paradoxical situation a century ago, but he also mapped out some paths for reaching a successful solution. A particular attention is paid to Peirce's classification of the sciences and to his conception of science (...) as a collective and cooperative activity of all those whose lives are animated by the desire to discover the truth. -/- .

In this paper the relations between the almost unknown Spanish mathematician Ventura Reyes Prósper (1863-1922) with Charles S. Peirce and Christine Ladd-Franklin are described. Two brief papers from Reyes Prósper published in El Progreso Matemático 12 (20 December 1891), pp. 297-300, and 18 (15 June 1892) pp. 170-173 on Ladd-Franklin, and on Peirce and Mitchell, respectively, are translated for first time into English and included at the end of the paper.

George M. Searle (1839-1918) and Charles S. Peirce worked together in the Coast Survey and the Harvard Observatory during the decade of 1860: both scientists were assistants of Joseph Winlock, the director of the Observatory. When in 1868 George, a convert to Catholicism, left to enter the Paulist Fathers, he was replaced by his brother Arthur Searle. George was ordained as a priest in 1871, was a lecturer of Mathematics and Astronomy at the Catholic University of America, and became the (...) fourth superior general of his congregation from 1904 to 1909. Among the books he wrote for non-Catholic audiences was Plain Facts for Fair Minds (1895). On the 8th of August of 1895, Peirce found that book in a bookstore and the following day wrote a letter to George Searle developing his strong reservations about the question of the infallibility of the Pope. This letter (L 397) is almost unknown amongst Peirce's scholars. -/- After describing these historical circumstances as a framework, the aim of my paper is to describe Peirce's arguments against papal infallibility presented by George Searle in his book, and the contrast between the genuine scientific attitude and the putative metaphysical notion of absolute truth that is —according to Peirce— behind Searle's defense of infallibility. In this sense, Peirce's fallibilism will be explained with some detail, giving an account also of his practical infallibilism: "The assertion that every assertion but this is fallible, is the only one that is absolutely infallible. But though nothing else is absolutely infallible, many propositions are practically infallible; such as the dicta of conscience" (Minute Logic, CP 2.75, c. 1902). -/- Finally, having in mind the present interest in Peirce's religious ideas it will be suggested that some of Peirce's ideas on infallibility are nearer to contemporary understanding of that issue than Searle's defense. "I would with all my heart join the ancient church of Rome if I could. But your book," —Peirce writes to Searle— "is an awful warning against doing so." -/- . (shrink)

In spite of a considerable progress in comorbidity research and huge literature on it, this phenomenon is one of the greatest epistemological, research and clinical challenges to contemporary psychiatry and medicine. Mental disorders are very often comorbidly expressed, both among themselves and with various sorts of somatic diseases and illnesses. Therefore, comorbidity studies have been expected to be an impetus to research on the validity of current diagnostic systems as well as on establishing more effective and effi cient treatment within (...) the frame of person centered transdisciplinary psychiatry and integrative medicine. This review focuses fi rst on conceptual chaos and different connotations, then on transdisciplinary perspectives of comorbidity and multimorbidity. The authors compiled an extensive set of various views and perspectives, dilemmas and controversies, in order to evaluate what we know and what we don’t about comorbidity, what comorbidity is and what comorbidity is not, what are facts and what are non-facts on comorbidity and multimorbidity.

Thirty years ago Richard Rorty detected the similarities between Wittgenstein's Philosophical Investigations (1953) and the philosophical framework of Charles S. Peirce (1839-1914), the founder of pragmatism. Rorty tried to show that Peirce envisaged and repudiated in advance logical positivism and developed insights and a philosophical mood very close to the analytical philosophers influenced by the later Wittgenstein (Rorty 1961). In spite of that, the majority of scholars have considered both thinkers as totally alien. Some scholars have attributed the pragmatist flavor (...) of the Philosophical Investigations to the influence of Frank P. Ramsey, who awoke Wittgenstein from the dogmatic slumber of the Tractatus. Nevertheless, the real scope of the influence of American pragmatist philosophy in Wittgenstein's later thought is not clearly known. The purpose of my paper is not to describe the common themes between Wittgenstein and Peirce, but the way in which recent scholarship has established some links between both philosophers. -/- .

One of the main proposers of these systems, Newton da Costa, asked Francisco Miró Quesada to suggest him a name for those systems.

This insight to art came from chess composition concentrating art in a very dense form. To identify and mathematically assess the uniqueness is the key applicable to other areas eg. computer programming. Maximization of uniqueness is minimization of entropy that coincides as well as goes beyond Information Theory (Shannon, 1948). The reusage of logic as a universal principle to minimize entropy, requires simplified architecture and abstraction. Any structures (e.g. plugins) duplicating or dividing functionality increase entropy and so unreliability (eg. British (...) Airways IT system). The ideas here were verified by my chess compositions, art works and complex information system as an author of each co uk, and were presented at conferences in Santorini, Adelaide, Geneva, Daejon and virtually.

The richer you are, the less equally rich or richer people. The richest is only one (=unique). Maximization of richness or leisure (=classic utility), maximizes the uniqueness (=improbability) that can be maximized also by: extreme sport, suicide, tattoo, count of views... The richest seem unique as the poorest, but the rich can easily become poor, while the poor can hardly get rich. So the aim of maximization reflects IQ and options. Few options increase irrationality, regardless of IQ. I also present (...) the law of values' equality, Utility of Suicide, motivation to support the better, and overview the economics as such.

The article presents the chess composition as a logical art, with concrete examples. It began with Arabic mansuba, and later evolved to new-strategy designed by Italian Alberto Mari. The redefinition of mate (e.g. mate with a free field) or a theme to quasi-pseudo theme, opens the new space for combinations, and enables to connect it with other fields like computer science.

Cognitive tests show that identity and symmetry reflect intellect. 'Guess of other guess' creates various symmetries, while only one is right: 'absolute symmetry', which can be outvoted by the majority. Prejudices result from differences between ME (my identity) and others. Unbiased judgement is symmetrical, always in the middle: neither in favor, nor against ME. Intelligence reduces prejudices, but the lack of opportunities can counterbalance it. That's why type of bias differs in various groups: people from war zones, people in therapy, (...) artists, etc.. "The law of values' equity" is a symmetrical principle redefining utility in economics, when people equate all their values. E.g. 2 children averagely rich, is better than one child rich and another poor. If 'a' is an average richness, and 'x' is a difference in richness, and Utility multiplies all values, then: a * a > (a - x) * (a + x), which is: a² > a² - x². It does not however imply egalitarianism, as it is still better to have both children rich than both average or poor. (shrink)

Although the cognition is significant in strategic reasoning, its role has been weakly analyzed, because only the average intelligence is usually considered. For example, prisoner's dilemma in game theory, would have different outcomes for persons with different intelligence. I show how various levels of intelligence influence the quality of reasoning, decision, or the probability of psychosis. I explain my original methodology developed for my MA thesis in clinical psychology in 1998, and grant research in 1999, demonstrating the bias of the (...) classic IQ method, and how the intelligence limits thinking. Based on that I defined Personality Model, providing insight into understanding of psychosis (schizophrenia, bi-polar), which has not been explained yet by psychology or psychiatry. In addition, it enables to analyze and assess non-linear problems, utilizable in computer programming, visualization (animation) or other fields including Baduk game. I've already applied some principles in complex information system www.each.co.uk, and video-animations exhibited in London, Germany, Tokyo. I need to mention my experience in chess composition between 1994 and 2000, winning a few international prizes and inventing a special class of fairy rules redefining the mate. The chess composition principles or patterns show the way to organize logical series to higher advanced mechanisms (like calculus), applicable to other fields. One of such principles is a logical aesthetic innovation: new strategy, defined by Italian composers. Finally I show how the simple redefinition of the classic utility concept links economics and psychology to explain irrational / destructive behavior.

In 1995, as a student of psychology inspired by natural science, I defined a logical model of personality explaining psychosis. I created (for my MA thesis, 1998 and grant research, 1999) new kind of tests assessing intelligence, creativity, prejudices, expectations to show more exact methods in psychology. During my Phd study in economics, I developed 'Maximization of Uniqueness (Originality)' model enhancing the classic utility to explain irrational motivations linking economics and psychology. Later I became computer programmer developing functional programming. According (...) to Personality model (and my experience in chess composition), I've built server and client logic of information system www.each.co.uk, and produced visual art.

It is technically possible to clone a human being. The result of the procedure would be a human being in its own right. Given the current level of cloning technology concerning other animals there is every reason to believe that early human clones will have shorter-than-average life-spans, and will be unusually prone to disease. In addition, they would be unusually at risk of genetic defects, though they would still, probably, have lives worth living. But with experimentation and experience, seriously unequal (...) prospects between cloned and noncloned people should erode. We shall ignore arguments about cloning that focus on the potential for harm to the fetus or resultant human being, where harm is understood solely in terms of physical and mental health. Unless the resultant people would generally have lives worth living there is no positive case for cloning, or any other form of reproduction, for that matter. If the resultant beings will generally have lives worth living there is a prima facie case for allowing cloning. We imagine the case in which the resultant beings will have lives well worth living.

A surge in post-publication activity related to editing, including by technical editors and copyeditors, is worthy of some discussion. One of these issues involves the issue of 'tortured phrases', which are bizarre terms and phrases in academic papers that replace standard English expressions or jargon.

Charles S. Peirce (1839-1914) made relevant contributions to deductive logic, but he was primarily interested in the logic of science, and more especially in what he called 'abduction' (as opposed to deduction and induction), which is the process whereby hypotheses are generated in order to explain the surprising facts. Indeed, Peirce considered abduction to be at the heart not only of scientific research, but of all ordinary human activities. Nevertheless, in spite of Peirce's work and writings in the field of (...) methodology of research, scarce attention has been paid to the logic of discovery over the last hundred years, despite an impressive development not only of scientific research but also of logic. -/- Having this in mind, the exposition is divided into five parts: 1) a brief presentation of Peirce, focusing on his work as a professional scientist; 2) an exposition of the classification of inferences by the young Peirce: deduction, induction and hypothesis; 3) a sketch of the notion of abduction in the mature Peirce; 4) an exposition of the logic of surprise; and finally, by way of conclusion, 5) a discussion of this peculiar ability of guessing understood as a rational instinct. -/- .

Twenty years ago I put a sign on the door to my office —and it’s still there— with the sentence of Peirce that I have used in my title: "The life of science is in the desire to learn" (CP 1.235, c.1902). I learned this quote from the late professor of logic at MIT, George Boolos. Like him, I put it on my door to invite students to come in to inquire, to ask questions, since their questions are not just (...) the life of science, but also the sparks that inflame my passion for teaching. Those —professors and students— who desire to learn are the real agents, the main characters, of philosophical development. Philosophy should not be understood and taught as the transmission of old solutions to outdated problems, but as a way of life devoted to learning the truth wherever we might find it. My exposition will be divided into four sections: 1) A brief presentation of Peirce, focusing on his work as a professional scientist and a scientific philosopher; 2) Peirce considered as an educational philosopher; 3) Some practical suggestions I have drawn from Peirce's ideas and from my experience teaching philosophy today; and finally, 4) A brief conclusion.

A surprising fact about the Hispanic philosophical historiography2 of the 20th century is its almost complete ignorance of the American philosophical tradition. This disconnect is even more surprising when one takes into account the striking affinities between the topics and problems treated by the most relevant Hispanic thinkers (Unamuno, Ortega, Vaz Ferreira, Ferrater Mora, Xirau) and the central questions raised in the most important native current of American thought in the late 19th and 20th centuries, pragmatism. In recent years there (...) has been a resurgence of pragmatist philosophy in contemporary culture, which is producing a deep renovation and transformation. One of the important features of this process is precisely the recuperation and improved understanding of the thought of Charles S. Peirce, who offers suggestions for dealing with some of the most persistent problems in contemporary philosophy, and who in addition can help us to reassume our responsibilities as philosophers, responsibilities that a good part of the philosophy of the 20th century had renounced. We can confidently say, as will be clear from what follows, that Spain and the Latin American countries are playing an important role in this increased understanding and diffusion of Peircean thought throughout the world.

According to Charles S. Peirce and to Mariano Artigas, science is the collective and cooperative activity of all those whose lives are animated by the desire to discover the truth. The particular sciences are branches of a common tree. The unity of science is not achieved by the reduction of the special sciences to more basic ones: the new name for the unity of the sciences is cross-disciplinarity. This is not a union of the sciences themselves, but rather the unity (...) and dialogue of scientists, the real inquirers into the truth. In the light of Peirce’s and Artigas’s teachings, we can see that philosophers are in just the right place to call for this unity of sciences. This call should not be seen as promoting a return to the old scientism, but seeks a deep dialogue between the particular sciences and philosophy in order to deal with the presuppositions of the scientific enterprise. The key to the cross-disciplinarity of knowledge is not revolution, but rather shared efforts in a unique mixture of continuity and fallibilism, of affection and reason, of the attempt to understand others’ disciplines as well as our own.

The aim of my paper is to highlight that for Peirce the reality of God makes sense of the whole scientific enterprise. The belief in God is a natural product of abduction, of the "rational instinct" or educated guess of the scientist or the layman, and also the abduction of God may be understood as a "proof" of pragmatism. Moreover, I want to suggest that for Peirce scientific activity is a genuine religious enterprise, perhaps even the religious activity par excellence, (...) and that to divorce religion from science is antithetical to both the scientific spirit and the real Peirce. Understanding the real Peirce requires to deal with his religious concerns, which are increasingly recognized as being perhaps as philosophically important as his scientific concerns. Since a key notion in this project is the idea of "il lume naturale" that Peirce borrowed from Galileo, I want also to pay attention to that expression which during years I have been following through Peirce's papers and books. -/- In order to try to explain some of this, my paper is arranged into four brief sections after this already long introduction: 1) God and scientific inquiry; 2) The belief in God as a product of abduction; 3) Galileo and Peirce: Il lume naturale; and by way of conclusion 4) Some remarks on the religious framework of Peirce's approach.

One usually makes assertions by means of uttering indicative sentences like “It is raining”. However, not every utterance of an indicative sentence is an assertion. For example, in uttering “I will be back tomorrow”, one might be making a promise. What is to make an assertion? C.S. Peirce held the view that “to assert a proposition is to make oneself responsible for its truth” (CP 5.543). In this thesis, I interpret Peirce’s view of assertion and I evaluate Peirce’s reasons for (...) holding it. I begin by reconstructing and assessing Peirce’s case for such view as it appears in (EP 2.140, 1903), (EP 2.312-313, 1904), and (CP 5.546, 1908). Then, I continue by elaborating on three aspects of Peirce’s view of assertion, namely, assertion as an act involving a certain kind of responsibility, the proposition as what is asserted, and responsibility for truth as a responsibility to give reasons. With respect to these three aspects, I argue for the following claims: (1) Peirce construed the responsibility involved in asserting as a moral responsibility; (2) Peirce held that propositions are types; and (3) Peirce was committed to a dialogical interpretation of “responsibility to give reasons”. Finally, I end by presenting two objections to Peirce’s view of assertion and its corresponding replies. I conclude that Peirce’s account of assertion is a valuable contribution to the philosophical debate on assertion. (shrink)

The Lewis-Sider argument from vagueness is one of the most powerful objections against restricted composition. Many have resisted the argument by rejecting its key premise, namely that existence is not vague. In this paper, I argue that this strategy is ineffective as a response to vagueness-based objections against restricted composition. To that end, I formulate a new argument against restricted composition: the argument from determinate vagueness. Unlike the Lewis-Sider argument, my argument doesn’t require accepting that existence is not vague, but (...) only that it is not vague in a specific way, which, I argue, is entailed by restricted composition. I show that the rejection of this species of vague existence follows from assumptions even friends of vague existence should be happy to accept. (shrink)

This paper investigates the semantics of implicit comparatives (Alice is tall compared to Bob) and its connections to the semantics of explicit comparatives (Alice is taller than Bob) and sentences with adjectives in plain positive form (Alice is tall).

The relationship between William James and Ludwig Wittgenstein (1889-1951) has recently been the subject of intense scholarly research. We know for instance that the later Wittgenstein's reflections on the philosophy of psychology found in James a major source of inspiration.

In this brief paper I merely want to piece together some of the available (...) evidence of Wittgenstein’s high regard for William James, not only for his thoughts, but even more so for his character.

"I do not call the solitary studies of a single man a science.

(MS 1334: 12–13, 1905). This beautiful quotation from Charles S. Peirce comes from his “Lecture I to the Adirondack Summer School 1905” and was catalogued as MS 1334 (Robin (...) 1967). In 1986 Kenneth L. Ketner chose fifteen pages (7–22) of the Notebook I of these lectures to represent Peirce’s conception of science in the volume Classical American Philosophy (Stuhr 1987: 46–48). “The Nature of Science” was the appropriate title assigned to that selection, which up to then had been almost unknown to the majority of Peirce scholars. Sara Barrena translated the piece into Spanish in 1996 (Barrena 1996: 1435–1440) and we chose the quotation above as the motto for our then incipient group of Peirce scholars in the Spanish- speaking world because it so finely expressed the aim of our undertaking. Against the traditional image of the philosopher as a solitary thinker near the stove, we wanted, following Peirce, to encourage cooperation and communication between our researchers not only as something useful, but as something essential for the real development of science.

In this paper Peirce's notion of sign is studied to try to characterize the artistic sign as representation. Then, some considerations about the work of art as a sign are developed involving three elements: experience, expression and interpretation. Finally it is concluded that beauty requires for Peirce a peculiar balance, the imaginative conjunction of the sensible and the reasonable in an artistic sign; it requires moreover the expression of something that transcends the sensible; it requires, as a sign, an interpretation (...) which is not exact and which implies growth. It requires, finally, love, because an artist will only reach beauty guided by agape updating and harmonizing possibilities through abduction, that is, creating new signs that give form to what does not have it; the artist only reaches beauty when he loves what he does and when he can express himself freely. -/- En este artículo se estudia, en primer lugar, la noción de signo de Peirce para tratar de caracterizar después el signo artístico como representación. Se desarrollan enseguida algunas consideraciones sobre la obra de arte como signo que como tal conlleva tres elementos: experiencia, expresión e interpretación. Finalmente se concluye que la belleza requiere para Peirce un peculiar equilibrio, la conjunción imaginativa de lo sensible y lo razonable en un signo artístico; requiere además la expresión de algo que trasciende lo sensible; requiere, en tanto signo, de una interpretación que no es exacta y que implica crecimiento. Requiere, por último, amor, pues el artista solo alcanzará lo bello cuando sea guiado por el ágape y a través de la abducción vaya actualizando y armonizando posibilidades, creando nuevos signos que den forma a lo que no la tiene, cuando ame lo que hace y se exprese libremente.

This entry is a presentation of C. S. Peirce and of his connections with A. N. Whitehead. Also Whitehead's connections with Peirce are explored.

El objetivo de esta colaboración es, en primer lugar, dar noticia de algunas coordenadas básicas de la discusión contemporánea acerca del lenguaje y la diferencia de los sexos, prestando especial atención a la acusación de esencialismo con la que se descalifican los contendientes entre sí. En segundo lugar, quiero llamar la atención acerca de la insuficiencia de las razones esgrimidas por el discurso feminista de la diferencia y por el discurso de la complementariedad cultural, que en última instancia vienen a (...) favorecer —en total oposición, sin duda, a los deseos de sus valedores— una perpetuación de la discriminación de las mujeres1. En tercer lugar, esbozo unas pautas para la eliminación de algunos elementos sexistas que todavía subsisten en la lengua española. -/- El trabajo se articula en cuatro secciones: 1) El debate contemporáneo sobre el esencialismo; 2) El discurso biológico sobre la diferencia sexual; 3) La construcción cultural de la diferencia sexual; y finalmente, 4) La búsqueda de un nuevo lenguaje. El propósito unificador que otorga sentido al conjunto radica en el empeño por ganar en comprensión de lo que es el ser humano mediante la reflexión filosófica sobre la diferenciación sexual que se detecta, se expresa o se crea, a través o en el lenguaje. La perspectiva que adopto —desde una óptica preferentemente hispánica, pero prestando especial atención a la cultura angloamericana— es decididamente filosófica, y aspira a integrar armónicamente aportaciones multidisciplinares, datos y planteamientos teóricos procedentes de las ciencias biomédicas y de las humanidades. Esta actitud supone una concepción de la filosofía que, lejos de un eclecticismo acrítico, busca encontrar las razones de la verdad en la confrontación de opiniones opuestas, sabedora con la mejor tradición que todos los pareceres formulados seriamente, en cierto sentido, dicen algo verdadero. Una segunda consecuencia de la adopción de esta perspectiva filosófica es que he evitado convertir el trabajo en una investigación lexicográfica de la lengua española, limitando ésta exclusivamente al final de la última sección.

The American novelist Walker Percy (1916-90) considered himself a "thief of Peirce", because he found in the views of C.S. Peirce, the founder of pragmatism, an alternative approach to prevailing reductionist theories in order to understand what we human beings are and what the peculiar nature of our linguistic activity is. -/- This paper describes, quoting widely from Percy, how abduction is the spontaneous activity of our reason by which we couple meanings and experience in our linguistic expressions. This coupling (...) of personal creativity and cultural tradition makes it possible to bridge the gaps between persons and cultures. (shrink)

Bertrand Russell was never to forget the course he gave in Barcelona in the spring of 1920. In the bitter title-page of An Inquiry into Meaning and Truth (1940), after the legal ruling which had suspended him from teaching at City College, New York, he expressly mentions his lectures in Barcelona, along with those he had given at the Universities of Uppsala and Copenhagen and at the Sorbonne. He also alludes briefly to them in his Autobiography (Russell 1990, II, 143), (...) but their circumstances and import have received no attention to date. The aim of this paper is to bring to light the available information on this subject in the Russell Archives (McMaster University, Canada) and the papers left by Joan Crexells (1896-1926) and Eugenio d'Ors (1881-1954), the two Catalan philosophers behind Russell's visit, and to put forward an assessment of Russell's influence on Spanish philosophy.

En diciembre de 1996 fui invitado a impartir una sesión a profesores de lógica en los estudios institucionales del Studium Generale de la Prelatura del Opus Dei. En aquella ocasión preparé concienzudamente un texto escrito que pasé a mi querido y admirado colega Ángel Luis González para su revisión. Pocos días después Ángel Luis me lo devolvió con unas pocas correcciones y sugerencias y un alentador “¡Mucho ánimo!” en su encabezamiento. Durante muchos años conservé ese texto con sus anotaciones manuscritas. (...) Por este motivo, me ha parecido que podría ser adecuado reproducir en este volumen en homenaje de Ángel Luis aquella exposición en forma abreviada con unas pocas correcciones y actualizaciones de detalle. Mi exposición se divide en tres partes: 1) Situación de la lógica en la filosofía contemporánea; 2) El papel de la lógica en los estudios institucionales; y termina con 3) A modo de conclusión, una reflexión más personal.

In this short paper I try to present William James’s connection with the Argentinian writer Macedonio Fernández (1874-1952), who was in some sense a mentor of Borges and might be considered the missing link between Borges and James.
