There is wide support in logic, philosophy, and psychology for the hypothesis that the probability of the indicative conditional of natural language, P(if A then B), is the conditional probability of B given A, P(B|A). We identify a conditional which is such that P(if A then B)=P(B|A) with de Finetti's conditional event, B|A. An objection to making this identification in the past was that it appeared unclear how to form compounds and iterations of conditional events. In this paper, we illustrate (...) how to overcome this objection with a probabilistic analysis, based on coherence, of these compounds and iterations. We interpret the compounds and iterations as conditional random quantities which, given some logical dependencies, may reduce to conditional events. We show how the inference to B|A from A and B can be extended to compounds and iterations of both conditional events and biconditional events. Moreover, we determine the respective uncertainty propagation rules. Finally, we make some comments on extending our analysis to counterfactuals. (shrink)

We analyze selected iterated conditionals in the framework of conditional random quantities. We point out that it is instructive to examine Lewis's triviality result, which shows the conditions a conditional must satisfy for its probability to be the conditional probability. In our approach, however, we avoid triviality because the import-export principle is invalid. We then analyze an example of reasoning under partial knowledge where, given a conditional if A then Cas information, the probability of A should intuitively increase. We explain (...) this intuition by making some implicit background information explicit. We consider several iterated conditionals, which allow us to formalize different kinds of latent information. We verify that for these iterated conditionals the prevision is greater than or equal to the probability of A. We also investigate the lower and upper bounds of the Affirmation of the Consequent inference. We conclude our study with some remarks on the supposed "independence" of two conditionals, and we interpret this property as uncorrelation between two random quantities. 2020 Elsevier Inc.

This paper proposes a critical analysis of that interpretation of the Nāgārjunian doctrine of the two truths as summarized—by both Mark Siderits and Jay L. Garfield—in the formula: “the ultimate truth is that there is no ultimate truth”. This ‘semantic reading’ of Nāgārjuna’s theory, despite its importance as a criticism of the ‘metaphysical interpretations’, would in itself be defective and improbable. Indeed, firstly, semantic interpretation presents a formal defect: it fails to clearly and explicitly express that which it contains logically; (...) the previously mentioned formula must necessarily be completed by: “the conventional truth is that nothing is conventional truth”. Secondly, after having recognized what Siderits’ and Garfield’s analyses contain implicitly, other logical and philological defects in their position emerge: the existence of the ‘conventional’ would appear—despite the efforts of semantic interpreters to demonstrate quite the contrary—definitively inconceivable without the presupposition of something ‘real’; moreover, the number of verses in Nāgārjuna that are in opposition to the semantic interpretation (even if we grant semantic interpreters that these verses do not justify a metaphysical reconstruction of Nagarjuna’s doctrine) would seem too great and significant to be ignored.

This paper proposes an interpretation of Nāgārjuna’s doctrine of the two truths that considers saṃvṛti and paramārtha-satya two visions of reality on which the Buddhas, for soteriological and pedagogical reasons, build teachings of two types: respectively in agreement with (for example, the teaching of the Four Noble Truths) or in contrast to (for example, the teaching of emptiness) the category of svabhāva. The early sections of the article show to what extent the various current interpretations of the Nāgārjunian doctrine of (...) the dve satye—despite their sometimes even macroscopic differences—have a common tendency to consider the notion of śūnyatā as a teaching not based on, but equivalent to supreme truth. This equivalence—philologically questionable—leads to interpretative paths that prove inevitably aporetic: indeed, according to whether the interpretation of śūnyatā is ‘metaphysical’ or ‘anti-metaphysical’, it gives rise to readings of Nāgārjuna’s thought incompatible, respectively, with anti-metaphysical and realistic types of verses traceable in the works of the author of the Mūla-madhyamaka-kārikā (MMK). On the contrary, by giving more emphasis to the expression samupāśritya (“based on”), which recurs in MMK.24.8, and therefore, by epistemologically separating the notion of śūnyatā from the notion of paramārtha-satya (and of some of its conceptual equivalents such as nirvāṇa, tattva and dharmatā), we may obtain an interpretation—at once realistic and anti-metaphysical—of the theory of the two truths compatible with the vast majority (or even totality) of Nāgārjuna’s verses.

Modus ponens (from A and “if A then C” infer C) is one of the most basic inference rules. The probabilistic modus ponens allows for managing uncertainty by transmitting assigned uncertainties from the premises to the conclusion (i.e., from P(A) and P(C|A) infer P(C)). In this paper, we generalize the probabilistic modus ponens by replacing A by the conditional event A|H. The resulting inference rule involves iterated conditionals (formalized by conditional random quantities) and propagates previsions from the premises to the (...) conclusion. Interestingly, the propagation rules for the lower and the upper bounds on the conclusion of the generalized probabilistic modus ponens coincide with the respective bounds on the conclusion for the (non-nested) probabilistic modus ponens.

In the first part of this paper I critically examine some of the main interpretations of “classical” Yogācāra philosophy of Maitreya, Asaṅga and Vasubandhu. Among these interpretations, based on extant textual and contextual data, I consider philologically unlikely both metaphysical-idealistic readings, which ascribe to these authors the view that ultimate reality is a mental or subjective stuff, and epistemological-idealistic readings which advocate that either Yogācāra suspends judgment on the existence of the extramental or that it maintains that the extramental exists (...) in itself and ultimately. Instead, I consider more likely the thesis that classical Yogācāra upholds an epistemological idealism that, while admitting epistemological priority of the mental over the extramental, rules out the ultimate existence of both the former and the latter. This exclusion, however, does not amount to the exclusion of every metaphysics, but rather to the adoption of a metaphysics of emptiness conceived, in fact, as absence of the mental/extramental dichotomy. In the second part of the paper this reading of classical Yogācāra is compared with the interpretation of Nāgārjuna’s philosophy that I elsewhere called “realistic antimetaphysical”, and I reach the conclusion that, while with respect to epistemology between early Madhyamaka and classical Yogācāra there is continuity, regarding metaphysics these two schools are deeply distinct and discontinuous: while Nāgārjuna conceives of emptiness as an extinction of any metaphysical view, Yogācāra emptiness actually presents itself as a metaphysical point of view.

This article reflects on a survey carried out at a non-profit organization that deals with health care for oncological terminally ill in order to find out for those who are involved in this project each worker's time projection and well-being class. The survey has pointed out each single team member's time perspective and well-being class and allowed building a pedagogical path for work orientation that has involved the same team members.

Serial homology, i.e., homology between repetitive structures in the same individual organism, is a debated concept in evolutionary developmental biology. The central question is the evolutionary interpretation of “sameness” in the context of the same body. This essay provides a synthetic analysis of the main issues involved in the debate, connecting conceptual problems with current experimental research. It is argued that a concept of serial homology that is not of the all-or-nothing kind can smooth several theoretical inconsistencies, while being more (...) in line with what we know about evolutionary change and the way we investigate it.

In _Historia animalium_ VIII 1.588a18 ff., Aristotle describes the cognitive powers of non-human animals as sketches of human cognitive powers. According to the wording he chooses here, the cognitive powers of non-human animals are “traces” or “footprints” (ἴχνη, 588a19) of human ones. In this paper I explore the conceptual framework that lays behind this image, in order to show that it is much more than a rhetorical figure, and that Aristotle’s wording encompasses a whole articulated theory, whose details are set (...) out in _De anima_ and the _Parva naturalia_. Moreover, I try to clarify some technicalities of the scientific model he devises in order to explain certain features of the sensory-perceptual part of the soul (with particular attention to the perception of the so-called “common” and “incidental” sensory items) that bear a real analogy to the functions of reason and intellect, and that can consequently be considered their precursors.

Some time ago I advanced on the pages of this journal a critique of the interpretation given by Jay L. Garfield and Mark Siderits (hereafter GS) of Nāgārjuna’s doctrine of the two truths (Ferraro, J Indian Philos 41(2):195–219, 2013.1); to my article the two authors responded with a ‘defense of the semantic interpretation’ of the Madhyamaka doctrine of emptiness (GS, J Indian Philos 41(6):655–664, 2013). Their reply, however, could not consider my personal understanding of Nāgārjuna’s notions of śūnyatā and dve (...) satye. My interpretation of these notions was in fact absent in the paper GS responded, and was only related in a second paper of mine (Ferraro, J Indian Philos 41(5):563–590, 2013.2), still unpublished at the time of GS’s drafting of their ‘defense’. Therefore, in the present rejoinder, I found it appropriate, rather than responding point by point to the passages of GS’s reply, to advance a comparison between the semantic interpretation and my ‘realist antimetaphysical’ understanding of Nāgārjuna’s thought.

A interpretação da filosofia de Nāgārjuna como um niilismo metafísico radical é comum tanto entre os autores antigos quanto nos estudos budológicos contemporâneos. Uma primeira leitura da doutrina da vacuidade proposta por esse autor, com efeito, parece levar à conclusão de que nada existe em última análise e, portanto, a realidade em si seria equivalente a um puro não-ser. Uma tal metafísica do nada, entretanto, seria duplamente problemática: primeiramente, ela parece sofrer de graves incovenientes lógico-conceituais; em segundo lugar, ela colocaria (...) Nāgārjuna fora da ortodoxia budista, por ser o niilismo uma doutrina explicitamente reprovada pelo Buda histórico. Uma leitura mais atenta e completa dos textos a nossa disposição, entretanto, nos leva a concluir que a filosofia do fundador da escola Madhyamaka não pode ser considerado como um niilismo metafísico, mas sim, ao invés disso, como uma tentativa de evitar e de eliminar qualquer metafísica, tanto afirmativa quanto negativa, em total acordo com o programa filosófico – já presente no ensinamento do Buda – do “caminho do meio”, equidistante das categorias do ser e do não-ser.

The purpose of this study is not so much to show the presence of Antisthenes in the dialogue, but rather to examine what Plato alludes to. The controversy over ideas between the two Socratics is historically very well-attested, as can already be seen in the Cratylus. Thus, it is reasonable to assume that this controversy must have affected Plato when he was writing a dialogue in which the importance of ideas and his new logic is undeniable. Hence, this paper will (...) investigate the following question: what impact could Antisthenes’ denominative and definitory logic have on the equally denominative and definitory logic presented in the Phaedo given that the latter work in all probability preceded the Sathōn? In light of what is said in the dialogue, the answer focuses primarily on what would not be said. Thus, this study has been divided into two parts: Part one shows how the so-called “second navigation” emerges as an objection to the insufficiency of the responses given by the physiologists. Tellingly, certain “common opinions” are regarded as perplexing and individuals holding them are referred to with the indeterminate tis, which – as is argued – must have included Antisthenes. Indeed, Tht. 108c7–8 reports the latter to have made common opinions a cornerstone of his denomi­native logic. Part two, on the other hand, is devoted to examining the so-called “final argument.” Here, Antisthenes’ presence seems some­what more nuanced given his incomplete knowledge of the new logic of irreversible opposites which was worked out by Plato for the purpose of demonstrating the immortality and indestructibility of the soul. On the other hand, Antisthenes is likely to have prompted Plato to specify the relationship between ideas and things in the definitory logic, since the proponent of the theory of oikeios logos refused to distinguish between the substance and its attributes, the differences and its opposites as well as the opposites of opposites.

We here report the findings of our investigation into the validity of the conjunction fallacy (Tversky & Kahneman, 1983), bearing in mind the role of conversational rules. Our first experiment showed that subjects found a logically correct answer unacceptable when it implied a violation of the conversational rules. We argue that tautological questions, such as those which concern the relationship of inclusion between a class and its sub-class, violate conversational rules because they are not informative. In this sense, it is (...) not understood that the question in a Linda-type problem involves a comparison between an inclusive and included class, but presumed that a different type of comparison is intended. Tautological questions (and, consequently, also their answers) do not become a matter of discussion except under certain specific conditions. Our second experiment showed that, providing the context was adequately marked (such as in the case of a rhetorical question), the conjunction fallacy disappears. In two further experiments, the implications of our view were compared with those of the other critical approaches to the heuristic programme: the classical pragmatic view (which we call logical complementarity) and the frequentist view.

Nas primeiras duas seções deste artigo, apresento alguns dos argumentos que os filósofos budistas indianos Nāgārjuna (ca. séculos II-III) e Vasubandhu (ca. séculos IV-V) usam para mostrar a insustentabilidade lógica dos fenômenos, respectivamente, do movimento e da existência de objetos externos/extramentais. A lógica desses argumentos é comparável à lógica que Zenão de Eleia utiliza nos seus paradoxos contra o movimento e a multiplicidade – e, de fato, no interior dos estudos budológicos contemporâneos, essa comparação já foi sugerida. Na terceira seção, (...) entretanto, pretendo mostrar que os objetivos filosóficos mais imediatos desses três pensadores divergem e são inconciliáveis: enquanto Zenão critica o movimento e a multiplicidade para demonstrar a plausibilidade dos atributos da imobilidade e da univocidade do Ser parmenídico, os paradoxos de Nāgārjuna e Vasubandhu devem ser entendidos no âmbito de projetos filosóficos que, em continuidade com o ensinamento budiano do caminho do meio, pretendem ficar equidistantes das categorias do “ser” e do “não-ser”, evitando ambas. Finalmente, na quarta e última seção, defendo a tese de que os objetivos últimos dos Eleatas e aqueles dos dois filósofos budistas voltam a ser parecidos: Parmênides e o Buda, como também seus respectivos epígonos, buscam promover nos seus seguidores uma “revolução epistêmica” que consiste na passagem de uma visão ordinária da realidade a uma compreensão extraordinária ou suprema, coincidente com a realidade em si e, portanto, verdadeira em última análise.

With regards the crucial issue of the existence of the self, within canonical texts of the Buddhist Abhidharma schools we find passages that are frequently at odds with one another. Sometimes the Buddha defends or respects the belief in the self and in personal continuity; at other times he seems to deny that beyond the psycho-physical factors to which our existential experience can be reduced there is an ātman that contains, owns or controls these same factors; in further cases still, (...) he states that the use of the metaphysical categories of “being” and “non-being” must be avoided – thus, about the self (or everything else), it is inappropriate to say that it exists or that it does not exist. Faced with these divergences (or contradictions) within contemporary Buddhist studies, we can detect two main tendencies. Some scholars start from the assumption that the Buddha’s teaching is or should be coherent and univocal, and, therefore, propose readings of his original message that are supposed to iron out or conciliate any inconsistencies. Others believe that the inconsistencies are actually irreconcilable and, therefore, maintain that the Abhidharma canons are a composite and stratified redaction in which the opposite views of different writers overlap and intersect. Against these historiographical approaches, the purpose of the present paper is to show that the three aforementioned modes of the Buddha’s teaching are, in fact, both alternative and irreconcilable. This, however, far from presenting a puzzle to be solved or explained (by resorting to suppositions of which, in the canons, we have no explicit confirmation), is nothing more than a feature of the Buddha’s Dharma, which appears to be a teaching that develops different pedagogical/soteriological modes for different purposes, and which is conceived for the spiritual growth of followers with different intellectual and psychological profiles.

The paper addresses the epistemological and theoretical assumptions that underpin the concept of Work and Organizational Psychology as idiographic, situated, and transformative social science. Positioning the connection between uniqueness and generalization inside the debate around organization studies as applied approaches, the contribution highlights the ontological, gnoseological, and methodological implications at stake. The use of practical instead of scientific rationality is explored, through the perspective of a hermeneutic lens, underlining the main features connected to the adoption of an epistemology of practice. (...) Specifically, the contribution depicts the configuration of the applied research as a relational practice, embedded in the unfolding process of generating knowledge dealing with concrete social contexts and particular social objects. The discussion of a case study regarding a field research project allows one to point out challenges and constraints connected to the enactment of the research process as a social accomplishment.
