We investigate the possibility to characterize (multi) functions that are Σ b i -definable with small i (i = 1, 2, 3) in fragments of bounded arithmetic T 2 in terms of natural search problems defined over polynomial-time structures. We obtain the following results: (1) A reformulation of known characterizations of (multi)functions that are Σ b 1 - and Σ b 2 -definable in the theories S 1 2 and T 1 2 . (2) New characterizations of (multi)functions that are (...) Σ b 2 - and Σ b 3 -definable in the theory T 2 2 . (3) A new non-conservation result: the theory T 2 2 (α) is not ∀Σ b 1 (α)-conservative over the theory S 2 2 (α). To prove that the theory T 2 2 (α) is not ∀Σ b 1 (α)-conservative over the theory S 2 2 (α), we present two examples of a Σ b 1 (α)-principle separating the two theories: (a) the weak pigeonhole principle WPHP (a 2 , f, g) formalizing that no function f is a bijection between a 2 and a with the inverse g, (b) the iteration principle Iter (a, R, f) formalizing that no function f defined on a strict partial order ( $\{0,\dots,a\}$ , R) can have increasing iterates.

They work and live in Milan.Girls Just wanna have fun: Goldschmied & Chiari's Irreverent HumorHumor is not a trait for women, even less so for women artists in the Italian art world, where women's creativity has historically focused either on intimacy or on abstraction. In order to be taken into consideration by a male-dominated art scene, women artists working in the Italian peninsula have, since the '70s, consistently been obliged to be extremely serious about their work and its content. This trait can be traced all the way to the present with few exceptions, making Goldschmied & Chiari's (Sara Goldschmied and Eleonora Chiari) artistic practice exceptional in its constant employment of a peculiar, irreverent form of humor that functions as subliminal social critique.Humor used as a strategy to reconsider historical events in a post-ideological form of feminism develops in their work in witty installations that articulate a lucid critique of contemporary society and its relationship to history. Radically distancing themselves from the stereotype of authoritative and earnest feminism, Goldschmied & Chiari turn laughter into a metaphor for transformation. Their images trigger subtle political disruptions, allowing them to delve into the complex history of post-Cold War narratives, offering the public a new understanding of the relationships between the symbolic and the social.My first encounter with Goldschmied & Chiari's work (goldiechiari at the time) dates back to 2002 when I was working on a large survey show of emerging Italian art, exIT: Nuove geografie della creatività italiana, curated by Francesco Bonami. I was surprised by their work Senza titolo #17 that portrayed in a full-color photograph two girls dressed as if they were in boarding school, in plaid skirts and colored stockings, with long braids, sitting on the floor helping an elderly "grandmother" knitting in her armchair by making a hank of yarn. Looking closer, one sees that the girls were actually adolescents trapped in a parody that the artists further highlighted by installing in front of the photo what looked like a gigantic ball of yarn but was actually a sphere made of 1,500 cm of barbed wire (Sfera, 2002). The "tableau vivant" quality of the image made it both funny and critical, as visitors could relate as much to the stereotyped enactment of women's domestic roles as to the artists' rebellious desire. Instead of relegating their creativity to the domestic sphere, these "mischievous little girls" had wound a menacing barbed-wire ball that evoked Italy's recent past of social unrest and urban guerrillas. The assumption of ironic activist alter egos in one way referenced feminist practices of the '70s, yet at the same time seemed to mock the violence associated with protest and its success. [End Page 116]This type of atmosphere linked to city barricades and acts of protest is the inspiration for a large... (shrink)

We investigate the problem how to lift the non - $\forall \Sigma^b_1(\alpha)$ - conservativity of $T^2_2(\alpha)$ over $S^2_2(\alpha)$ to the expected non - $\forall \Sigma^b_i(\alpha)$ - conservativity of $T^{i+1}_2(\alpha)$ over $S^{i+1}_2(\alpha)$ , for $i > 1$ . We give a non-trivial refinement of the “lifting method” developed in [4,8], and we prove a sufficient condition on a $\forall \Sigma^b_1(f)$ -consequence of $T_2(f)$ to yield the non-conservation result. Further we prove that Ramsey's theorem, a $\forall \Sigma^b_1(\alpha)$ - formula, is not provable (...) in $T^1_2(\alpha)$ , and that $\forall \Sigma^b_j(\alpha)$ - conservativity of $T^{i+1}_2(\alpha)$ over $T^{i}_2(\alpha)$ implies $\forall \Sigma^b_j(\alpha)$ - conservativity of the whole $T_2(\alpha)$ over $T^{i}_2(\alpha)$ , for any $j \geq 2$.

Il presente contributo indaga la questione del fondamento della legge morale ebraica sulla scorta dell’insegnamento di Samuel David Luzzatto (1800-1865). Egli afferma che le norme etiche sono insite nell’essere umano, ma questo non basta perché vengano rispettate: la rivelazione divina sostiene quindi la morale naturale, senza insegnare nulla di diverso da quest’ultima, ma fornendo un’adeguata propedeutica e prevedendo sanzioni e premi chiari. Soltanto il monoteismo, con il suo necessario corollario cultuale, può dunque fondare una morale efficace, che si manifesta (...) essenzialmente nel praticare umanità e giustizia verso tutti gli esseri umani. This paper investigates the Jewish moral law’s foundation according with teaching of Samuel David Luzzatto (1800-1865). He affirms that ethical norms come from human being, but this is not enough for them to be respected: therefore divine revelation supports natural morality, teaching the same, but providing adequate preparation and providing penalties and rewards. Only monotheism, with its necessary worships, can therefore found an effective morality. It appears essentially in humanity and justice towards all human beings. (shrink)

Recent Anglophone scholarship has successfully shown that Nietzsche's thought makes important contributions to a wide range of contemporary philosophical debates. In so doing, however, scholarship has lost sight of another important feature of Nietzsche's project, namely his desire to challenge the very conception of philosophy that has been used to assess his merits as a philosopher. In other words, contemporary scholarship has overlooked Nietzsche's contributions to metaphilosophy, i.e. debates around the nature, methods, and aims of philosophy. This important new collection (...) of essays brings together an international group of distinguished scholars to explore and discuss these contributions and debates. It will appeal to anyone interested in metaphilosophy, Nietzsche studies, German studies, or intellectual history. (shrink)

A series of experiments investigated the effect of speakers’ language, accent, and race on children’s social preferences. When presented with photographs and voice recordings of novel children, 5-year-old children chose to be friends with native speakers of their native language rather than foreign-language or foreign-accented speakers. These preferences were not exclusively due to the intelligibility of the speech, as children found the accented speech to be comprehensible, and did not make social distinctions between foreign-accented and foreign-language speakers. Finally, children chose (...) same-race children as friends when the target children were silent, but they chose other-race children with a native accent when accent was pitted against race. A control experiment provided evidence that children’s privileging of accent over race was not due to the relative familiarity of each dimension. The results, discussed in an evolutionary framework, suggest that children preferentially evaluate others along dimensions that distinguished social groups in prehistoric human societies. (shrink)

Peirceana provides a forum for the best current work on Peirce worldwide. Besides monographs, the series will publish thematically unified anthologies and edited volumes with a defined topical focus and untranslated English selections of Peirce's writings.

Volume 6 of this landmark edition contains 66 writings mainly from the unsettled period in Peirce’s life just after he moved from New York to Milford, Pennsylvania, followed shortly afterward by the death of his mother. The writings in this volume reveal Peirce’s powerful mind probing into diverse issues, looking for an underlying unity, but, perhaps, also looking for direction.

The starting point of my study is Kant’s remark to the effect that Garve in his treatise on the connection between morality and politics presents arguments in defence of unjust principles. Recognition of these principles is, according to Kant, an inadvisable concession to those who are inclined to abuse it. I interpret this judgement by making a detailed comparison of the texts of the two treatises. I demonstrate that Garve’s work is an eclectic attempt to combine in one concept the (...) lessons of historical experience with the ideas drawn from British empiricism and German rationalism. These ideas were criticised by Kant in his “critical” period. There is a consensus among researchers that Garve condoned the expansionist policy of Frederick II of Prussia, totally denied that legality in international relations was possible and in general deserved the reputation of an conservative. From that point of view the key values for Garve were the security and well-being of the state. I offer an alternative interpretation of Garve’s position because I believe that the value of political stability plays an important role in it. Such an interpretation makes it possible to treat Garve’s narrative as it was assessed by Kant, i.e. as a concession to the common principles of political practice as a result of a failure to find the guiding theory. My study has established that the role of Garve’s work in the writing of Kant’s treatise Toward Perpetual Peace was more significant than Kant’s own words suggest. Besides, I show that it was under Garve’s influence that Kant turned to the problem of excessive complexity of the principles involved in the search for concrete political decisions. Garve obviously laments this complexity and yet makes these principles still more complex. Kant offers a simpler solution of the problem on the basis of his theory of morals and right. (shrink)
