It is well-known that by 1882, Peirce, influenced by Cayley’s, Clifford’s and Sylvester’s works on algebraic invariants and by the chemical analogy, had already achieved something like a diagrammatic treatment of quantificational logic of relatives. The details of that discovery and its implications to some wider issues in logical theory merit further investigation, however. This paper provides a reconstruction of the genesis of Peirce’s logical graphs from the early 1880s until 1896, covering the period of time during which he already (...) was acquainted with the works of his Johns Hopkins colleagues on the mathematical theory of graphs and was reaching the very first forms of his theory and method of...

The aim of this article is to discuss pure variable inclusion logics, that is, logical systems where valid entailments require that the propositional variables occurring in the conclusion are included among those appearing in the premises, or vice versa. We study the subsystems of Classical Logic satisfying these requirements and assess the extent to which it is possible to characterise them by means of a single logical matrix. In addition, we semantically describe both of these companions to Classical Logic in (...) terms of appropriate matrix bundles and as semilattice-based logics, showing that the notion of consequence in these logics can be interpreted in terms of truth (or non-falsity) and meaningfulness (or meaninglessness) preservation. Finally, we use Płonka sums of matrices to investigate the pure variable inclusion companions of an arbitrary finitary logic. -/- . (shrink)

The auctions of the Federal Communication Commission, designed in 1994 to sell spectrum licences, are one of the few widely acclaimed and copied cases of economic engineering to date. This paper includes a detailed narrative of the process of designing, testing and implementing the FCC auctions, focusing in particular on the role played by game theoretical modelling and laboratory experimentation. Some general remarks about the scope, interpretation and use of rational choice models open and conclude the paper.

How can we investigate the foundations of consciousness? In addressing this question, we will focus on the two main strategies that authors have adopted so far. On the one hand, there is research aimed at characterizing a specific content, which should account for conscious states. We may call this the content approach. On the other hand, one finds the processing approach, which proposes to look for a particular way of processing to account for consciousness.. Our aim, in this paper, is (...) to develop arguments for the latter approach. We focus on a criticism of Jesse Prinz’s AIR theory of consciousness. We have chosen Prinz’s theory because it incorporates features of both the content and processing approaches, and discussing it will therefore allow us to compare the advantages and downsides of both. Our argument will focus in particular on the notion of intermediate-level. We will discuss how Prinz characterizes the intermediate-level according to a content approach, and argue that such a characterization is inadequate. Finally, we will argue in favor of processing approach to the problem of consciousness, which also accounts for the massive interaction of top-down and bottom-up processes in the brain. Even though consciousness remains an unsolved riddle, we claim that this is the best path towards a solution. (shrink)

In this article I investigate what the Stoic doctrine of the two principles, God and matter, owes to Plato. I discuss recent scholarly views to the effect that the Stoics were influenced by Old Academic interpretations of the Timaeus and argue that, although the Timaeus probably did play a role in the genesis of the Stoic doctrine, some role was also played by a dualist theory of flux set forth in the etymologies of the Cratylus. I also discuss Theophrastus’ account (...) of Plato’s achievements in physics (fr. 230 FHS&G) and the report of Old Academic physics contained in Cicero’s Academica, 1. 24–9, and commonly taken to go back to Antiochus of Ascalon, and I show that those reports too are likely to have been influenced by the Cratylus.

This paper argues that Umberto Eco had a sophisticated theory of abductive reasoning and that this theory is fundamentally akin to Peirce’s both in the analysis and in the justification of this kind of reasoning. The first section expounds the essentials of Peirce’s theory of abduction, and explains how Peirce moved from seeing abduction as a kind of reasoning to seeing it as a stage of the larger process of inquiry. The second section deals with one of Eco’s paradigmatic examples (...) of abduction, i.e., William of Baskerville’s abduction concerning the horse Brunellus in the overture of The Name of the Rose, and shows that, just like in Peirce’s three-stages model of inquiry, William’s abductions are verified by means of deduction and induction. The third section examines the problem of the justification of abductive reasoning, and argues that both Peirce and Eco solved this problem through the idea that the justification of abduction is itself abductive (meta-abduction in Eco, ur-abduction in Peirce).

For four decades, research on the role and responsibilities of business in society has centered on the business case for corporate social responsibility (CSR) and an increasing number of studies on the corporate social performance (CSP)—corporate financial performance (CFP) link emerged leading to controversial results. Heeding the call for a deeper understanding of the mechanisms linking certain CSR efforts to certain performance outcomes, this study provides a stakeholder-based organizing framework rooted in an extensive review of existing literature on the link (...) between CSP and CFP. In so doing, we aim at guiding research and practice toward less simplistic understandings of the CSP–CFP connection, thus advancing the debate over the consequences of voluntary integrating CSR into business operations and into relationships with stakeholders. By disentangling specific drivers and outcomes of the CSP–CFP link, we underline the importance of setting clear boundaries and specifying levels of analysis to generate comparable results. (shrink)

This paper first discusses how Russell and Hochberg have addressed some phenomena of relatedness, notably relational order, in a similarly ‘positionalist’ way, yet by appealing to different sorts of formal relations: “positions” in Russell's case and “ordering relations” in Hochberg's. After pointing out some shortcomings of both approaches, the paper then proposes an alternative view based on ‘o-roles’, which are, roughly speaking, ontological counterparts of the thematic roles postulated in linguistics. It is argued that o-roles are sort of middle-of-the-road entities (...) in the sense that they have the virtues of positions and those of ordering relations, without having their respective vices. Some tentative ideas on which o-roles should be acknowledged are also put forward. (shrink)

The paper discusses the passages of Vico's letters and "Scienza nuova prima" (1725) concerning Grotius and blaming him as a "Socinian". First of all, it tries to identify the sources which allowed Vico to see Grotius as a hidden Socinian. In fact, these sources exist and they are to find in German debates on Natural Right, since many exponents of Lutheran and Calvinian "orthodoxy" expressed similar doubts on Grotius. In particular, the works of Guilelmus Van der Muelen (1659-1739) may have (...) been influencial on Vico, since they considered carefully Grotius' view on the most ancient customs and rights as proofs that Grotius considered the most ancient peoples as better and more sociable than actual ones, a naturalist view which cannot be conciliated with the doctrine of the original sin and with the importance of religion for the acquisition of the virtue of justice. These sources can explain Vico's decision to elaborate his view of the origin of civil society, starting with the simplicity of the "bestioni" but who can arrive to civility only through the fear and horror for natural wonders (the thunder) and the religious awe derivating from it.

The thin red line theory is a form of branching indeterminism. It entails that, among the many possible developments that reality might take, one is privileged: the actual history. The thin red line theory is naturally paired off with a semantic thesis that may be called ‘the actuality principle’: a statement is true as used at a moment if and only if it is true at that moment on the actual history. The actuality principle has been challenged, for it would (...) be wrong about several counterfactual reasonings. On the one hand, the actuality principle should entail that any statement uttered at a merely possible moment is untrue. On the other hand, the actuality principle should be at odds with the way we use subjunctive conditionals. This paper argues that both objections rely on an inadequate understanding of the notion of the history of use. As for the first objection, the paper argues that to assume the actuality principle amounts to taking the actual history as the history of use. As a consequence, one cannot consistently take the actual history as the history of use and, at the same time, a merely possible moment as the moment of use. As for the second objection, the paper shows that the actuality principle is consistent with any reasonable treatment of subjunctive conditionals. (shrink)

Corporate social responsibility (CSR) is gaining momentum in the business world, but several issues continue to challenge managers in charge of sustainability. Supply chain management is one area in which CSR-related activities could potentially drive the process of sustainability within firms. This case presents the way that illycaffè, an Italian coffee producer, has approached CSR. Since 1991, the company has focused on developing a new relationship with Brazilian coffee producers based on networking translated into knowledge transfer—Brazilian producers became responsible for (...) their operations all along the supply line—and innovation translated into quality—one supplier talks about how illycaffè persuaded him he was capable of producing a Ferrari among coffees instead of a Fiat. These two factors not only drive the supplier relationship, but also serve as the drivers of illycaffè’s sustainability strategy. Lessons for managers relate to benefits for the business, for society and for stakeholders, and questions arise about how to replicate illycaffè’s success and create value through values. (shrink)

Research suggests that moral evaluations change during adulthood. Older adults (75+) tend to judge accidentally harmful acts more severely than younger adults do, and this age‐related difference is in part due to the greater negligence older adults attribute to the accidental harmdoers. Across two studies (N = 254), we find support for this claim and report the novel discovery that older adults’ increased attribution of negligence, in turn, is associated with a higher perceived likelihood that the accident would occur. We (...) propose that, because older adults perceive accidents as more likely than younger adults do, they condemn the agents and their actions more and even infer that the agents’ omission to exercise due care is intentional. These findings refine our understanding of the cognitive processes underpinning moral judgment in older adulthood and highlight the role of subjective probability judgments in negligence attribution.

The desire of knowledge constitutes, as it is well known, the opening ‘theme’ of Aristotle’s Metaphysics. This article focuses on the figure of Dominic of Flanders, one of the commentators of Aristotle’s Metaphysics who much developed this topic. Dominicus deals with it in the second question of the first book of his commentary. What makes the interest of Dominic’s account is its originality, in so far as, according to him, the beginning of Aristotle’s Metaphysics aims to stress the very primacy (...) of Metaphsyics, and not only, the primacy of science in general. In this sense, the desire of knowledge constitutes for Dominic the most efficacious argument for the primacy of Metaphsyics. However, this is possible only if the desiderium sciendi is related to two other principles: the first is that desirability entails perfection, and the second is that the desirability of an object depends on its intelligibility.
