In her recent book, Russell (2023) examines various so-called “barriers to entailment,” including Hume’s law, roughly the thesis that an ‘ought’ cannot be derived from an ‘is.’ Hume’s law bears an obvious resemblance to the proscription on fallacies of modality in relevance logic, which has traditionally formally been captured by the so-called Ackermann property. In the context of relevant modal logic, this property might be articulated thus: no conditional whose antecedent is box-free and whose consequent is box-prefixed is valid (for (...) the connection, interpret box deontically). While the deontic significance of Ackermann-like properties has been observed before, Russell’s new book suggests a more broad-scoped formal investigation of the relationship between barrier theses of various kinds and corresponding Ackermann-like properties. In this paper, I undertake such an investigation by elaborating a general relevant bimodal logical framework in which several of the barriers Russell examines can be given formal expression. I then consider various Ackermann-like properties corresponding to these barriers and prove that certain systems satisfy them. Finally, I respond to some objections Russell makes against the use of relevance logic to formulate Hume’s law and related barriers. (shrink)

Without directly addressing the Demarcation Problem for logic—the problem of distinguishing logical vocabulary from others—we focus on distinctive aspects of logical vocabulary in pursuit of a second goal in the philosophy of logic, namely, proposing criteria for the justification of logical rules. Our preferred approach has three components. Two of these are effectively Belnap’s, but with a twist. We agree with Belnap’s response to Prior’s challenge to inferentialist characterisations of the meanings of logical constants. Belnap argued that for a logical (...) constant to exist, its rules must be conservative over a previously given consequence relation and guarantee the uniqueness of the constant. The twist is that we require logical vocabulary to be provably conservative, not over a previously given formal consequence relation, but over a previously given meaningful vocabulary of a language. Uniqueness is also a feature defined in terms of provability: if two syntactically distinguished expressions are governed by the same rules, then formulas with them as main operators are interderivable. Belnap’s criteria are not only those for the existence of a logical constant, but more: they are what distinguishes logical vocabulary from all other expressions. It is the defining mark of a logical constant that it is provably conservative over the fragment of the language which excludes it and that its rules guarantee its uniqueness. The third component is the topic neutrality of logic. The provable conservativeness of logic over a previously given vocabulary of a language is motivated, in part, by appeal to molecularism in the theory of meaning. Molecularity is a feature endorsed by the theory of meaning as a whole, so it does not distinguish logical constants from other expressions. The same is true for conservativeness. We argue that molecularity, and hence conservativeness, are implicit presuppositions of speakers’ use of language: the addition of new vocabulary to a language is presupposed to be conservative. But this presupposition is one that we should be able reflectively to endorse (such as when attempting a rational reconstruction of the use of the vocabulary). Thus, where conservativeness is found to fail, this defect should be remedied and the use of the vocabulary corrected (as in classical negation) or excised altogether (as in pejoratives). We go on to characterise a notion of topic neutrality, which we argue applies to logical vocabulary. We then note that reflective endorsement of the conservativeness of a topic neutral vocabulary requires a proof that the vocabulary is conservative relative to any base vocabulary. Thus we require that logical vocabulary be demonstrably conservative. Allying this requirement, distinctive of logic, to a general consideration about the commitments of assertion yields a mode of justification for logical constants akin to some conceptions of Harmony, i.e., to the idea that the consequences of assertion of a logical complex need to be warranted by the grounds and ought to be the strongest consequences warranted by the grounds. Intuitionistic logic acquires a somewhat familiar justification but emanating from a new motivation. (shrink)

Fine (2007) argues that Frege’s puzzle and its relatives demonstrate a need for a basic reorientation of the field of semantics. According to this reorientation, the domain of semantic facts would be closed not under the classical consequence relation but only under a stronger relation Fine calls “manifest consequence.” I examine Fine’s informally sketched analyses of manifest consequence, showing that each can be amended to determine a class of strong consequence relations. A best candidate relation emerges from each of the (...) two classes, and I prove that the two candidates extensionally coincide. The resulting consequence relation is of independent interest, for it might be held to constitute a cogent standard of reasoning that proceeds under a deficient grasp on the identity of objects.

Among Dunn’s many important contributions to relevance logic was his work on the system RM (R-mingle). Although RM is an interesting system in its own right, it is widely considered to be too strong. In this chapter, I revisit a closely related system, RM0 (sometimes known as ‘constructive mingle’), which includes the mingle axiom while not degenerating in the way that RM itself does. My main interest will be in examining this logic from two related semantical perspectives. First, I give (...) a purely operational bisemilattice semantics for it by adapting previous work of Humberstone. Second, I examine a more conventional algebraic semantics for it and discuss how this relates to the operational semantics. A novel operational semantics for J (intuitionistic logic) as well as its conventional Heyting algebraic semantics emerge as special cases of the corresponding semantics for RM0. The results of this chapter suggest that RM0 is a more interesting logic than has been appreciated and that Humberstone’s operational semantic framework similarly deserves more attention than it has received.

I present a reconstruction of the logical system of the Tractatus, which differs from classical logic in two ways. It includes an account of Wittgenstein’s “form-series” device, which suffices to express some effectively generated countably infinite disjunctions. And its attendant notion of structure is relativized to the fixed underlying universe of what is named. -/- There follow three results. First, the class of concepts definable in the system is closed under finitary induction. Second, if the universe of objects is countably (...) infinite, then the property of being a tautology is \Pi^1_1-complete. But third, it is only granted the assumption of countability that the class of tautologies is \Sigma_1-definable in set theory. -/- Wittgenstein famously urges that logical relationships must show themselves in the structure of signs. He also urges that the size of the universe cannot be prejudged. The results of this paper indicate that there is no single way in which logical relationships could be held to make themselves manifest in signs, which does not prejudge the number of objects.

What is the role of affective experience in explaining how our desires provide us with reasons for action? When we desire that p, we are thereby disposed to feel attracted to the prospect that p, or to feel averse to the prospect that not-p. In this paper, we argue that affective experiences – including feelings of attraction and aversion – provide us with reasons for action in virtue of their phenomenal character. Moreover, we argue that desires provide us with reasons (...) for action only insofar as they are dispositions to have affective experiences. On this account, affective experience has a central role to play in explaining how desires provide reasons for action. (shrink)

Naturalist views of persons, such as those of the philosophers Annette Baier and Marjorie Grene, emphasize that human persons are cultural animals: We are living, embodied, organic beings, embedded in nature, the product of Darwinian evolution, but dependent on culture. Such naturalist views of persons typically eschew science fiction and look askance at the philosophical fantasies and thought experiments that often populate philosophical treatments of personal identity. Marge Piercy’s dystopian, cyberpunk, science fiction novel He, She and It weaves a complex (...) tale around the debate over the status of its central character Yod, a cyborg created in a lab but humanized through the efforts of two women, Malkah Shipman and her granddaughter Shira Shipman. Is Yod a person, despite having been engineered in a lab for a specific purpose? Piercy’s tale both challenges and ultimately supports a naturalist view of persons while simultaneously forewarning us of possible new styles of persons to come. (shrink)

This piece lays out the framework for a special issue on the topic of "Fits and Misfits," published as volume 7, issue 1 of Puncta: A Journal of Critical Phenomenology. We discuss the relationship between the concept of misfitting, coined by Rosemarie Garland-Thomson, and debility, coined by Jasbir Puar, in relationship to scholarship on Merleau-Ponty. We then introduce each of the eight articles in the special issue: Rosemarie Garland-Thomson's "What Misfitting Makes," Susan Bredlau's "Conversational Accessibility: Healthcare, Community, and the Ethics (...) of Everyday Encounters," Helen A. Fielding's "Being Touched by Wellness: Merleau-Ponty, Nancy, and the Intensive Care Unit," Ann Murphy's "The Spirited Interworld: Caregiving and the Liminal Phenomenology of Dementia," Rachel Elliott's "Sharing Time with Misfits: We-Experience across Bodily Difference," David Morris's "An-Archic Time: Melting the Clock as Hypernorm of the I Can -- and Philosophy," Rebecca Longtin's "Merleau-Ponty's Cézanne as Misfit Artist," and, finally, Laura McMahon's "The Politics of Vulnerability and the School for Peace: Insights from Butler, Merleau-Ponty, and Family Systems Theory.".

In Beyond Physicalism, an interdisciplinary group of physical scientists, behavioral and social scientists, and humanists from the Esalen Institute’s Center for Theory and Research argue that physicalism must be replaced by an expanded scientific naturalism that accommodates something spiritual at the heart of nature.

One of the virtues of this edited collection is the diversity contained within it. There is diversity to be found in the uses made of Wittgenstein's writings, reflecting the diversity of ways of understanding religion found in Wittgenstein's work. Andrejč, in his introduction (3), suggests that there are four dominant ways in which Wittgenstein depicts religion: the nonsensicalist, existentialist, grammaticalist and instinctivist conceptions of religion.

Analytical philosophy is ruled by the alliance of logic, linguistics and mathematics since its beginnings in the syllogistic calculus of terms and premises in Aristotle's Analytica protera, in the theories of medieval logic that dealt with what are Proprietatis Terminorum (significatio, suppositio, appellatio), in the theological apologetics of argumentation with the combinatorics of symbols by Raymundus Llullus in the work Ars Magna, Generalis et Ultima (1305-08), in what is presented as Theologia Combinata (cf. Tomus II.p.251) in Ars Magna Sciendi sive (...) Combinatoria by Athanasius Kircher (1669), in analytical combinatorics based in Leibniz's dissertation Ars Combinatoria (1666), where language is understood as a lingua characteristica and as a calculus ratiocinator, in the combinatorics of classes that have the meanings 1 or 0 given in the idea of Boolean functions (1854), in Frege's work Begriffschrift, eine der arithmeticeschen nachgebildete Fomelsprache des reinen Denkens (Concept letter, the language of formulas of pure thought made according to the model in arithmetical language), in Cantor's study of set theory / Grundlagen einer allgemeinen Mannigfaltigkeitstheorie (1883) and up to algorithms of fuzzy logic as a "means of approximate thinking that is in the human prior" (Zadeh, 1990) and fuzzy linguistics in computer semantics (Burghard B. Rieger, 1993). These are all the philosophical ideas of mathematicians and logicians that founded what we call logical pragmatism here as a demand that logic be absolutely used in every way in which it will dominate the grammar of language until logic itself becomes the philosophical grammar of the mind!!!

Two recently published oral histories highlight the long-term trend concerning the mainstreaming of Objectivism, the political and economic ideas of the libertarian conservative writer and ideologue, Ayn Rand. Scott McConnell’s sympathetic interview collection focuses on supporters and acquaintances from Rand’s active period in the 1960s and 1970s. These supporters and acquaintances include former Australian Prime Minister, Malcolm Fraser, who provides McConnell with his considered views concerning Rand. Gary Weiss’s critical interview collection focusses on her more recent supporters, with one (...) displeased and insightful interviewee to be found in both collections. Weiss’s collection reveals the role played by Objectivists in galvanizing the focus of the populist Tea Party movement. Both oral histories reveal the role played by the media and popular culture in mainstreaming Rand’s views. The review ends by comparing Randolph Stow’s socially responsive individualism as described in his novel 'Tourmaline' with Rand’s transactional individualism as described in 'Atlas Shrugged.'.

This paper evaluates the claim that some desires provide reasons in virtue of their connection with conscious affective experiences like feelings of attraction or aversion. I clarify the nature of affective desires and several distinct ways in which affective desires might provide reasons. Against accounts proposed by Ruth Chang, Declan Smithies and Jeremy Weiss, I motivate doubts that it is the phenomenology of affective experiences that explains their normative or rational significance. I outline an alternative approach that centralises the (...) function of such experiences. (shrink)

Als Goethe in seiner monumentalen Farbenlehre (1810) versuchte, Newtons Theorie des Lichts und der Farben anzugreifen, setzte er eine Methode ein, die er als Vermannigfachung der Erfahrungen bezeichnete: Er variierte verschiedene Parameter der newtonischen Experimente, um neuen Spielraum für Alternativen zur Theorie Newtons zu gewinnen. Dabei erzielte er durchaus Erfolge. U.a. entdeckte er das Komplement zum newtonischen Spektrum (das aussieht wie dessen Farbnegativ und durch Vertauschung der Rollen von Licht und Finsternis entsteht). Ingo Nussbaumer hat Goethes Methode kongenial fortgeführt. Dabei (...) hat er sechs weitere Farbspektren entdeckt. Sie entstehen, wenn man anstelle des Hell/Dunkel-Kontrasts (in Newtons und Goethes Experimenten) mit Paaren von Komplementärfarben arbeitet. Die neuen Farbspektren sehen genauso differenziert aus wie Newtons und Goethes Spektrum; doch anders als diese enthalten sie die unbunten "Farben" Schwarz und Weiss. Die vielfältigen Ordnungsbeziehungen und Symmetrien, die Ingo Nussbaumer in der Farbenwelt der insgesamt acht Spektren ausgemacht hat, verhelfen uns vielleicht zu einem tieferen Verständnis der Prinzipien menschlicher Farbwahrnehmung. Abgesehen davon haben sie einen hohen ästhetischen Reiz. Und sie regen dazu an, über kontrafaktische Verläufe der Wissenschaftsgeschichte zu spekulieren: Wie gut hätte sich Newtons Theorie des Lichts und der Farben in den Jahren nach ihrer Veröffentlichung (1672) durchsetzen können, wenn damals das newtonische Spektrum zusammen mit seinen sieben Gegenstücken bekannt geworden und daher nicht das einzige Spektrum gewesen wäre, mit dem die Theorie hätte fertigwerden müssen?

This research paper aims to study the cultural representations of the causes of corona pandemic (Covid 19) on the representations of the therapeutic itinerary on an among sample of Algerian society. These representations reveal the inter-relationship between the medical and the cultural representations through beliefs, ideas, and behaviors . Within this context, we applied EMIC questionnaire (The Explanatory Model Interview Catalogue). (MITCHELL G. WEISS, 1992) We used an online form in which a sample of 70 individuals (M, F), aged (...) from 20 to 50 years old, answered to. We relied on the quantitative and qualitative method in analyzing and interpreting the results. We came to the following results in the absence of a medical treatment, family solidarity and prevention measures are key treatments. In addition, the causes tend to be purely human, in the absence of all guaranteed treatments, whether therapeutic or traditional. (shrink)

In this article I examine two mathematical definitions of observational equivalence, one proposed by Charlotte Werndl and based on manifest isomorphism, and the other based on Ornstein and Weiss’s ε-congruence. I argue, for two related reasons, that neither can function as a purely mathematical definition of observational equivalence. First, each definition permits of counterexamples; second, overcoming these counterexamples will introduce non-mathematical premises about the systems in question. Accordingly, the prospects for a broadly applicable and purely mathematical definition of observational (...) equivalence are unpromising. Despite this critique, I suggest that Werndl’s proposals are valuable because they clarify the distinction between provable and unprovable elements in arguments for observational equivalence.

● Un emplazamiento cualquiera (v. gr. sol en Tauro; Marte en Capricornio; Mercurio en la tercera casa) es necesariamente común a decenas de miles de personas. Saturno hospedado en la novena casa, por ejemplo, no se comportará de la misma manera o no producirá los mismos efectos en las veinte o cien cartas en que allí lo encontremos, sino en concordancia con el resto de la composición astrográfica (como hospedarnos en el mismo hotel en diferentes épocas o diferentes personas haber (...) contraído la misma enfermedad; nuestra estadía será diferente cada vez, según la época, y no todos los enfermos presentarán los mismos síntomas, según su metabolismo; por no mencionar que cada astrografía, como cada código o secuencia genética, es irrepetible). Ciertamente, “ningún planeta puede, por sí solo, producir lo que solamente la acción mancomunada o conjunta de todos puede” (BUSTAMANTE, 2023, revista SPICA, págs. 93-111). He aquí la naturaleza o condición sinérgica del ejercicio interpretativo (i.e., el todo es poco más que la suma de todas sus partes). ● El componente fundamental de la expresión matemática del ejercicio interpretativo lo constituye la triangulación astrológica, denominación funcional de lo que conocemos como síntesis (WEISS, 1946; LEO, 1983; HAND, 1981). ● Con el fin de demostrar su utilidad, así como la conveniencia de su expresión matemática, hemos escogido dos individuos (JEFFREY DAHMER, STEVEN SPIELBERG) cuyas astrografías no explican, según la comunidad, sus vidas. El resto de las astrografías corresponden a las de los asesinos en serie JOHN WAYNE GACY, DAVID CARPENTER y TED BUNDY. ● A través de notaciones algebraicas, explicamos la síntesis y los valores funcionales que la componen. ● Tomamos la luna y Neptuno como planetas relevantes a propósito del diagnóstico o el estudio de asuntos endocrinos o neurohormonales y a Marte, Plutón y Saturno como planetas relevantes a los fines de inferir violencia o comportamiento siniestro, según el caso, y las cuadraturas u oposiciones —y conjunciones— entre Venus y la luna, la luna y Neptuno o entre el sol o Venus y Neptuno o Urano como indicadores de desórdenes neurohormonales y/o de desviación sexual (definición APA) . ● Consideramos las cuadraturas u oposiciones —y conjunciones— entre: Mercurio o la luna y Saturno, o entre Marte o la luna y Saturno, Urano, Neptuno y/o Plutón como poderosos indicios de violencia o de desequilibrio, según el caso. ● También hemos considerado a Sagitario como un signo tan expansivo y abundante como su regente, Júpiter, según la mejor de sus caracterizaciones (o excepcionalmente raudo y salvaje, según otras), y a la quinta región de un mapa natal como una estrechamente relacionada con la fortuna en sentido amplio (material e inmaterial). ● Debido a que defendemos la idea según la cual los orbes deben predicarse del planeta (tamaño, velocidad), no del aspecto, a los gigantes gaseosos (Júpiter, Saturno, Urano y Neptuno) y al sol les hemos concedido hasta 10º de orbe (o 12º, en el caso de la influencia amplia ). ● Entendemos las relaciones aspectuales como relaciones angulares sostenidas entre dos o más cuerpos celestes emplazados en signos con al menos una propiedad en común (según nuestra teoría molecular de la eclíptica, compatible con la teoría óptica de los aspectos de la tradición helenística).

● Any given placement (e.g. Sun in Taurus; Mars in Capricorn; Mercury in the third house) is necessarily common to tens of thousands of people. Saturn in the ninth house, for example, will not behave the same or produce the same effects in the twenty or one hundred charts in which we find it there. In each case Saturn will behave in accordance with the rest of the astrographic/chart composition (as if we stayed in the same hotel in different epochs (...) or different people contracted the same disease; our stay will be different each time, according to the epoch, and each person’s symptoms will too, be different, according to their individual biochemistry; not to mention that each chart or astrography, like each genetic code or sequence, is unrepeatable). Certainly, “no planet can produce, on its own, what only the combined or concerted action of all can” (BUSTAMANTE, 2023, SPICA magazine, pp. 93-111). Hence the synergistic nature of the interpretative exercise (i.e., the whole is greater than all its parts). The fundamental component of the mathematical expression of the interpretive exercise is: astrological triangulation, the functional denomination for what we know as synthesis (WEISS, 1946; LEO, 1983, HAND, 1981). In order to demonstrate its usefulness, as well as the convenience of its mathematical expression, we have chosen two individuals (JEFFREY DAHMER, STEVEN SPIELBERG) whose astrographies do not—according to the community—explain their lives. The rest of the astrographies correspond to those of serial killers JOHN WAYNE GACY, DAVID CARPENTER, and TED BUNDY. ● We explain, by means of algebraic notations, the synthesis and the functional values that make up the synthesis. ● We take the Moon and Neptune as relevant bodies for the purpose of diagnosing or studying endocrine or neurohormonal issues, and Mars, Pluto, and Saturn as relevant planets for the purpose of inferring violence or sinister behaviour, upon the case, and quadratures or oppositions—and conjunctions—between Venus and the Moon, the Moon and Neptune, and the Sun or Venus and Neptune or Uranus as indicators of neurohormonal disorders and/or sexual deviance (APA definition) . ● We consider quadratures (90º) or oppositions (180º)—and conjunctions—between Mercury or the Moon and Saturn, or between Mars or the Moon and Saturn, Uranus, Neptune, and/or Pluto as powerful indications of violence or mental disorders, upon the case. ● We have also regarded Sagittarius as a sign as expansive and abundant as its ruler, Jupiter, according to the best of its characterisations (or as an exceptionally swift and wild sign, according to other characterisations), and the fifth region of a natal chart as one closely related to fortune in a broad sense (material and immaterial). ● Because we advocate the idea that orbs should be predicated of the planet (size, speed), not the aspect itself, the gas giants (Jupiter, Saturn, Uranus, and Neptune) and the Sun have been granted up to 10º of orb (or 12º, in the case of broad influence ). We understand aspectual relationships as angular relationships held between two or more celestial bodies placed in signs with at least one property in common (according to our molecular theory of the ecliptic, compatible with the optical theory of the aspects from the Hellenistic tradition).

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

ecientemente hemos podido asistir a una revitalización del debate sobre la primacía del Derecho de la Unión Europea y los eventuales límites de la misma que algunos tribunales constitucionales defienden para preservar la identidad constitucional y otros principios esenciales del orden jurídico interno. -/- El Tribunal Constitucional Federal alemán ha declarado, en sentencia de 5 de mayo de 2020, que la sentencia Weiss y otros del Tribunal de Justicia de la UE es ultra vires. La reacción mayoritaria institucional y (...) doctrinal ha sido la de cuestionar la decisión del Tribunal alemán, así como el pluralismo constitucional que entienden está detrás de la misma. -/- Este trabajo, desde una perspectiva abierta y plural, trata de aproximarse al debate constitucional, identificar algunos de los problemas existentes en el orden jurídico multinivel europeo, y defender que, no siendo las cosas fáciles, se hace más necesario que nunca huir de posiciones absolutas y buscar el diálogo entre tribunales.

Che cosa vuol dire per le espressioni del nostro linguaggio avere un significato? Secondo un approccio oggi sostanzialmente standard in semantica, avere significato vuol dire prima di tutto avere un contenuto rappresentazionale, cioè poter rappresentare qualcosa. Secondo un inferenzialista come Robert Brandom, invece, le espressioni del nostro linguaggio hanno contenuto perché sono inserite in una rete di relazioni inferenziali, rispetto alla quale possono essere utilizzate per dare e richiedere ragioni. Il libro di Pietro Salis, Pratiche discorsive razionali, presenta e discute (...) alcuni degli aspetti più interessanti dell'inferenzialismo normativo di Brandom. Si tratta della seconda monografia in lingua italiana dedicata alla filosofia del linguaggio brandomiana dopo quella di Giovagnoli (2004). Per trovare elementi di paragone con il lavoro di Salis occorre allora guardare alle pubblicazioni in lingua inglese. Tra queste ci sono le raccolte di saggi curate da Stekeler-Weithofer (2008), Prien e Schweikard (2008), e Weiss e Wanderer (2010). Ma anche le introduzioni monografiche di Wanderer (2008) e Turbanti (2017). La prima di queste introduzioni, in particolare, è quella più simile al libro di Salis, soprattutto dal punto di vista tematico. (shrink)
