The philosophical analysis of mathematical explanations concerns itself with two different, although connected, areas of investigation. The first area addresses the problem of whether mathematics can play an explanatory role in the natural and social sciences. The second deals with the problem of whether mathematical explanations occur within mathematics itself. Accordingly, this entry surveys the contributions to both areas, it shows their relevance to the history of philosophy and science, it articulates their connection, and points to the philosophical pay-offs to (...) be expected by deepening our understanding of the topic.

It is usually maintained that a subject with manifestly contradictory beliefs is irrational. How can we account, then, for the intuitive rationality of dialetheists, who believe that some manifest contradictions are true? My paper aims to answer this question. Its ultimate goal is to determine a characterization of (or rather a constraint for) rational belief approvable by both the theorists of Dialetheism and its opponents. In order to achieve this goal, a two-step strategy will be adopted. First, a characterization of (...) rational belief applicable to non-dialetheist believers will be determined; this characterization will involve the semantic apparatus of Nathan Salmon’s Millian Russellianism but will get rid of the problematic and obscure notion of mode of presentation (guise in his own terminology), replacing it with a couple of novel devices, belief subsystems and cognitive coordination. Second, using ideas from Graham Priest, the leading proponent of Dialetheism, such a characterization will be modified, so as to devise a new one able to account for the intuitive rationality of both dialetheist and non-dialetheist believers.

_An examination of the philosophical notion of sacrifice from Kant to Nietzsche._.

Questo testo nasce da alcune indagini sul nesso tra matematica e filosofia in ambiente “accademico”. È interessante notare che l'esplorazione di tale nesso costituisce un felice tratto di continuità tra gli studi più classici e ...

Chapter Θ10 of Aristotle's Metaphysics is traditionally taken to be about the truth of intuitions, namely episodes of an immediate and sub-propositional grasp of entities. This exegesis however saddles Aristotle with a broken-backed theory of truth because in other passages of his works he claims that truth and falsehood apply only to items of a propositional nature and denies that sub-propositional items can be true or false. An alternative exegesis is preferable which takes Θ10 to be about the truth of (...) existential statements and judgements concerning simple items. (shrink)

The two theories of pancreatic enzyme secretion, those of exocytosis and transmembrane flow, are described. Data thought to support the theory of transmembrane flow of single molecules from pancreatic acinar cells are first reviewed, and the conditions which could allow these data to be explained by the theory of exocytosis of enzyme quanta, i.e. secretory granules, are then discussed.The evidence suggesting short‐term modulation of the composition of pancreatic juice is also considered, and its possible explanations at the organ and cellular (...) level are discussed, in the light of suggested theories on enzyme secretion pathways.

La introducción de la figura jurídica del “microtraficante” en la legislación penal chilena provoca un aumento de la violencia institucional, a nivel simbólico y material, hacia los sectores marginales de la población. ¿Cuáles tópicos, “lugares comunes”, fundamentan el cambio legislativo? Los conceptos “droga” y “drogadicto’’, entre otros, se configuran adentro del “espacio retórico prohibicionista”, cerrado entre los horizontes políticos de la criminalización y/o medicalización. Por eso el autor argumenta sobre la necesidad de abrir el “espacio retórico prohibicionista”, promoviendo una cultura (...) sociojurídica de las drogas desde la despenalización y legalización de su consumo.

In 1959, the Charles Darwin Station and the Galápagos National Park were established, formally inaugurating conservation on the archipelago. In the same year, a utopian colony from the United States arrived. Whereas scholars have dismissed the latter and focused on the former, this essay unveils the science-inspired utopianism common to both enterprises. Investing science with the exclusive role of producing all knowledge and steering politics, leaders of the two initiatives aspired not only to protect nature but also to forge a (...) new humanity. Describing how such ambitions burst along lines of race, class, and nationality, I argue that these enterprises consolidated the current understanding of the Galápagos as “pristine”: a site fit for research and tourism but unhospitable to people. Drawing on archival and historical documents, this essay aims to reinvigorate two conversations: one between science and technology studies and conservation, and the other between STS and utopian studies. If recent attempts at bridging the divide between science and imagination have emphasized how powerful actors shape human society, this essay considers the long-lasting effects of scientific imaginaries on a politics of nature.

We recorded Event-Related Potentials to investigate differences in the use of gender information during the processing of reflexive pronouns. Pronouns either matched the gender provided by role nouns (such as “king” or “engineer”) or did not. We compared two types of gender information, definitional information, which is semantic in nature (a mother is female), or stereotypical (a nurse is likely to be female). When they followed definitional role-nouns, gender-mismatching pronouns elicited a P600 effect reflecting a failure in the agreement process. (...) When instead the gender violation occurred after stereotypical role-nouns the Event Related Potential response was biphasic, being positive in parietal electrodes and negative in anterior left electrodes. The use of a correlational approach showed that those participants with more “feminine” or “expressive” self sex-role descriptions showed a P600 response for stereotype violations, suggesting that they experienced the mismatch as an agreement violation; whereas less “expressive” participants showed an Nref effect, indicating more effort spent in linking the pronouns with the possible, although less likely, counter-stereotypical referent.

Si tratta di una raccolta di saggi scritti tra il '65 e il '69 e pubblicati una prima volta nel 1971. Rivisti e parzialmente aggiornati vengono riproposti con la vecchia introduzione nella quale l'autore polemizza con le critiche della ragione scientifica che caratterizzarono alcuni aspetti della cultura del '68. Il primo saggio è dedicato al declino della astrologia all'inizio dell'età moderna; sottolineando il divario tra la concezione magica che caratterizza la visione astrologica del mondo e le posizione di quella che (...) sarebbe diventata la scienza, Paolo Rossi rivaluta gli scritti contro l'astrologia di Pico della Mirandola. Dopo un breve scritto su Leonardo, l'autore analizza i rapporti tra pensiero baconiano e cristianesimo. Segue un saggio che riesamina alcuni problemi di interpretazione delle lettere di Galileo a Piero Dini e a Cristina di Lorena. Nei capitoli successivi vengono affrontate varie questioni quali, il passaggio dalla concezione aristotelica a quella moderna, il peso di alcune ipotesi astronomiche e in particolare la crisi dell'antropocentrismo. Gli ultimi due capitoli dedicati a dispute di linguistica e di geologia sono particolarmente interessanti; infatti queste due discipline occupano una posizione anomala nella cultura del seicento. Se a quel tempo esistevano matematici, astronomi, medici, non si può certo parlare di linguisti o geologi propriamente detti, questo fatto rende particolarmente difficile e interessante ricostruire lo sviluppo di concetti appartenenti a branche della scienza che non erano ancora consce della loro autonomia.

La riflessione sulla cosmologia è uno degli aspetti meno noti del pensiero di Agazzi. Tuttavia, benché ne abbia scritto solo in poche occasioni e alcune considerazioni siano state superate dai grandi progressi scientifici nel frattempo intercorsi, altre sue intuizioni appaiono tuttora sorprendentemente attuali e feconde, forse ancor di più di quando furono formulate, come cercherò di mostrare in questo articolo. Su questa base tenterò inoltre di proporre una definizione precisa dell'oggetto proprio della cosmologia scientifica e di chiarire i suoi corretti (...) rapporti con la filosofia della natura e la metafisica.
