A widely debated issue in contemporary metaphysics is whether the modal profile of ordinary objects has to be explained in non-modal terms (that is, Thesis 1). However, how to solve such an issue with respect to occurrences – namely, processes and events – is a question that has been largely neglected in the current metaphysical debate. The general goal of this article is to start filling this gap. As a first result of the article, we make it plausible that, if (...) Thesis 1 holds for objects, then it also holds for processes and events. Then, we develop a metaphysical account of processes derived from Fine’s (1999, 2022) suggestions, according to which a process is a variable embodiment that is manifested by different events at the different times it goes on – namely, Thesis 2. We raised the challenge from the completion of a process that asks the Finean account of processes to explain relevant modal features of processes in non-modal terms. As a second result, we argue that four initially plausible strategies for solving such a challenge fall short of solving it. As a third result, we show that the theory of variable embodiments Fine formulates for objects must differ from the theory of variable embodiments that aims to model processes. We conclude by investigating some revisions to a theory of variable embodiments that aims to model processes. (shrink)

Processes are occurrents that were, are, or will be happening. They endure or they perdure, i.e. they are either “fully” present at every time they happen, or they rather have temporal parts. According to Stout (2016), they endure. His argument assumes that processes may change. Then, Stout argues that, if something changes, it endures. As I show, Stout’s Argument misses its target. In particular, it makes use of a notion of change that is either intuitive but illegitimate or technical but (...) question-begging. (shrink)

Monists and pluralists disagree concerning how many ordinary objects there are in a single situation. For instance, pluralists argue that a statue and the clay it is made of have different properties, and thereby are different. The standard monist’s response is to hold that there is just a single object, and that, under the description “being a statue”, this object is, e.g., aesthetically valuable, and that, under the description “being a piece of clay”, it is not aesthetically valuable. However, Fine (...) provided an ontological reading of the expression “an object under a description”: the theory of rigid embodiments. The debate between monists and pluralists reduplicates in the domain of ordinary occurrences, like walks and conferences. Specifically, they disagree whether an occurrence in progress (also called “process”) like John’s walk that is happening at tn is identical to some completed occurrence (also called “event”) like John’s walk that happened between, e.g., t1 and tn. Under the adoption of the pluralist’s position, the article aims to provide a novel theory of ordinary occurrences that develops the ontological reading of “under a description” to account for occurrences in progress and completed occurrences. As a first result, we formulate a theory according to which both occurrences in progress and completed occurrences are rigid embodiments. As a second result, we argue that the suggested theory is explanatorily powerful to the extent it solves two puzzles that we call “the Puzzle from the Completion of a Process” and “the Metaphysical-cum-Semantical Puzzle”.

This essay addresses the interrelations between philosophy and experimental sciences that lie at the heart of Carl Stumpf’s epistemology. Following a biographical exposé demonstrating how Stumpf succeeded in acquiring a dual competence in both philosophical and scientific fields, we examine the vast array of academic disciplines encompassed by his research. Such a biographical treatment aims, indeed, to better promote the thrust of Stumpf’s assertion that philosophical enquiries should always be carried out in close connection with scientific practices, and underlines how (...) philosophico-scientific interactions established his work as a central pillar in the history of late nineteenth- and early twentieth-century German thought.

The theory of variable embodiments has been primarily formulated to model ordinary objects as things that change their parts over time. A variable embodiment /f/ is a sui generis whole constructed from a principle f, the principle of a variable embodiment, and it is manifested at different times by different things picked out by such a principle f. This principle is usually clarified as a function that picks out, at any given time the variable embodiment exists, its corresponding manifestation at (...) that time, and it fails to pick out anything at any other time. The first purpose of this article is to examine and refute three natural understandings of such a principle. Specifically, first, we argue against the view that it should be understood extensionally as either a partial function or total function. Next, we provide some motivations to reject the understanding of the principle as a function in intensional terms, where the notion of intension is analyzed in terms of a specific version of a possible world semantics. The second goal of the article is to make it plausible that the principle has an intensional character and, on the basis of the results achieved, to formulate some constraints that an account of such a principle should meet.

The literature on indicative conditionals contains two appealing views. The first is the selectional view: on this view, conditionals operate by selecting a single possibility, which is used to evaluate the consequent. The second is the informational view: on this view, conditionals don’t express propositions, but rather impose constraints on information states of speakers. Both views are supported by strong arguments, but they are incompatible on their standard formulations. Hence it appears that we have to choose between mutually exclusive options. (...) But the options are not exclusive. This paper develops a theory of the semantics and assertability of conditionals that is both selectional and informational. The theory vindicates the signature inferences of both selectional and informational theories, including so-called Conditionals Excluded Middle and principles about the interplay between conditionals and ‘might’. It also predicts some interesting and puzzling facts about the assertion of conditionals. (shrink)

A growing conceptual and empirical literature is advancing the idea that language extends our cognitive skills. One of the most influential positions holds that language – qua material symbols – facilitates individual thought processes by virtue of its material properties (Clark, 2006a). Extending upon this model, we argue that language enhances our cognitive capabilities in a much more radical way: the skilful engagement of public material symbols facilitates evolutionarily unprecedented modes of collective perception, action and reasoning (interpersonal synergies) creating dialogically (...) extended minds. We relate our approach to other ideas about collective minds ( Gallagher, 2011, Theiner et al., 2010 and Tollefsen, 2006) and review a number of empirical studies to identify the mechanisms enabling the constitution of interpersonal cognitive systems.

Psychedelic-Assisted Psychotherapy is being investigated as a treatment for a range of psychiatric illnesses. Current research suggests that the kinds of subjective experiences induced by psychedelic compounds play key roles in producing therapeutic outcomes. To date, most knowledge of therapeutic psychedelic experiences are derived from psychometric assessments with scales such as the Mystical Experience Questionnaire. While these approaches are insightful, more nuanced and detailed descriptions of psychedelic-induced changes to subjective experience are required. Drawing on recent advancements in qualitative methods arising (...) from the interdisciplinary field of phenomenological psychopathology, we propose a systematic and comprehensive investigation into how Psychedelic-Assisted Psychotherapy alters subjective experience. This research program aims to characterise the nature of therapeutic psychedelic experiences by drawing on concepts from philosophical phenomenology. Such characterisations should, moreover, contribute to our understanding of the mechanisms of psychedelic therapy, the role of integration therapy, and related philosophical debates. (shrink)

This article focuses on the reception of Aristotle’s Categories by the first three representatives of Greek Neoplatonism: Plotinus (204/205–270 CE), Porphyry (ca. 234–ca. 305 CE), Iamblichus (ca. 242–ca. 325 CE). The first section argues that Plotinus’ acquaintance with Aristotle’s treatises marked a fresh start vis-à-vis the previous Platonist tradition. Aristotle’s views, arguments and vocabulary are ubiquitous in Plotinus writings (the Enneads) and they must be considered an essential part of his philosophical project. Plotinus, however, does not share some of Aristotle’s (...) key theories and is critical of them. The second section focuses on Plotinus’ discussion of Aristotle’s Categories in the tripartite treatise On the Genera of Being (6.1–3). There he rejects the Peripatetic division into ten categories as providing an incomplete account of the genera of being that unduly omits “those which are most authentically beings”, i.e. Plato’s separate Forms. While drawing on earlier Platonist objections to Aristotle, Plotinus’ approach is original insofar as he criticizes Aristotle and his followers not only for omitting intelligible beings in the division of categories, but also for being unable, for this very reason, to work out an adequate division of sensible beings themselves. The third section is devoted to Porphyry, a student of Plotinus’ and the editor of his works. Porphyry worked intensively on Aristotle’s Categories, which he regarded as an introduction not only to logic, but to philosophy as a whole. Unlike Plotinus, Porphyry aimed to integrate Aristotle into Platonism and his engagement with the Categories was a key part of his project after Plotinus’ in-depth criticism. Porphyry’s approach is connected to his view of the subject-matter of the Categories, which he sees as focusing on words insofar as they signify beings, and not on beings as such. The fourth section focuses on some parallels between Plotinus’ Genera of Beings and Porphyry’s works, which may reflect the debate within Plotinus’ school. The fifth section focuses on Iamblichus of Chalcis. Both in theology and in the interpretation of Aristotle’s Categories, Iamblichus aimed to both continue and supplant Porphyry’s work. While Plotinus criticizes Aristotle’s categories for omitting intelligible beings, and while Porphyry accepts Aristotle’s categories insofar as they focus on words signifying sensible things, Iamblichus incorporates his Neoplatonist and Pythagorizing metaphysics into the interpretation of the Categories.

The paper provides some introductory comments and a preliminary translation of Avicenna’s Burhān, IV, 2. I shall first set the stage by outlining the structure of the book (sec. 1). I will then briefly introduce (sec. 2) a number of notions that are dealt with in the first treatise of the Burhān (e.g. definition, description). Burhān, IV, 2 is split into two parts: the first focuses mainly on Aristotle’s An. Post., B, 4, whereas the second covers some of the topics (...) of B, 5 and B, 6. Accordingly, sec. 3 will be devoted to a cursory presentation of Aristotle’s arguments in An. Post., B, 4 along with a more detailed discussion of its Avicennan counterpart, focusing on the indemonstrability of definition; sec. 4, finally, will be a presentation of the second part of the chapter, concerning the relationship between definition and division. An English translation of the entire chapter is appended to the paper and is accompanied by some notes. (shrink)

Recent crises in Europe and beyond have renewed a longstanding debate on the status and treatment of refugees. Hannah Arendt famously questioned the limits of universalistic human rights discourse based on the widespread phenomena of statelessness and displacement that emerged during and after World War II. In this paper, we analyze recent patterns of inclusion and exclusion of refugees in Italy through the lens of Arendtian narrative and theorizing. We consider three cases of interaction between families, schools, and other public (...) institutions in light of the shifting normative framework before and during the war in Ukraine. Two major insights emerge from this analysis. From a pedagogical point of view, the most promising educational practices with refugees are those centered on enabling their agency and corresponding experiences of "natality". From an ethical-political perspective, these practices highlight a latent tension between the universalistic scope of human rights enshrined in the human rights declarations and their structural dependence on the particular norms and procedures enacted by nation states. The understanding and teaching of human rights within our political communities is inseparable from the practices that engage with refugees. In this sense, our practices of inclusion and exclusion affect the understanding of national borders as a barrier or threshold with other political communities, but also the interpretation of our own ethical-political principles.

This essay illustrates the main aspects of the discussion between Brentano and Stumpf about «tonal fusion». In his Tonpsychologie, Stumpf essentially moved from a Brentanian standpoint. Yet, he did not adopt Brentano’s subsequently developed new theory of «sensible qualities», so that a polemic eventually arouse between them. Far from representing a marginal issue, the episode is relevant to our understanding of their relationship. The discussion as to the mechanism of tonal fusion reveals a general divergence between Brentano and Stumpf concerning (...) the idea of human sensibility as a whole and of the method of psychology.

Hegel’s treatment of character in §395 of Encyclopedia is considered together with the commentaries given in his lectures. In these texts Hegel addresses some philosophical problems concerning character. In Hegel’s view, in fact, human character has a “natural basis” and yet depends on a free individual choice. Attention is drawn at Kant’s treatment of the same subject matter in Anthropology form a pragmatic point of view, which is the source of Hegel’s tripartite arrangement of Naturell, temperament and character. Diverging from (...) Kant, however, Hegel introduces a dialectic development within the development of character. (shrink)

Trust is an attitude that an agent (the trustor) has toward an entity (the trustee), such that the trustor counts upon the trustee to act in a way that is benefi- cial w.r.t. to the trustor’s goals. The notion of trust is relevantly discussed both in in- formation science and philosophy. Unfortunately, we still lack a satisfying account for this concept. The goal of this article is to contribute to filling this gap. First, we take issue with some central tenets (...) shared by the main philosophical accounts, such as that there is just one relation of trust, that this relation has three argument places, and that trust is reliance plus some extra factor. Second, we provide a novel account of trust, also discussing different levels of trust. According to the account we put forth here, the logical form of trust sentences is expressed by a four-place relation. Further, we distinguish and characterize four kinds of trust relations and their connections. We also argue that trust and reliance are different phenomena. Third, on the basis of the proposed account, we extend the Reference Ontology of Trust (ROT). We call the new version of ROT that includes this extension ”ROT 3.0”. Finally, we discuss the implications of the new ontological definitions in the applications we have done of the concept of trust in other works, also pointing out future applications made possible by these novel accounts of trust.

In his Spinozastudien Stumpf dismisses the commonplace interpretation of Spinoza’s parallelism in psychophysical terms. Rather, he suggests to read Ethics, II, Prop. 7, as the heritage of the scholastic doctrine of intentionality. Accordingly, things are the intentional objects of God’s ideas. On this basis, Stumpf also tries to make sense of the puzzling spinozian doctrine of the infinity of God’s attributes. In support of this exegesis, Stumpf offers an interesting reconstruction of the history of intentionality from Plato and Aristotle to (...) the late Scholastics. Besides its intrinsic value, Stumpf’s confrontation with Spinoza is illuminating in explaining his own position concerning a crucial phenomenological question such as intentionality. Actually, Stumpf avoids defining the mental in terms of intentionality and maintains, rather, a moderate but professed dualistic position, thus deeply diverging from both Brentano and Husserl.

Large Language Models (LLMs) are generative AI systems capable of producing original texts based on inputs about topic and style provided in the form of prompts or questions. The introduction of the outputs of these systems into human discursive practices poses unprecedented moral and political questions. The article articulates an analysis of the moral status of these systems and their interactions with human interlocutors based on the Habermasian theory of communicative action. The analysis explores, among other things, Habermas's inquiries into (...) the analogy between human minds and computers, and into the status of atypical participants in the linguistic community such as genetically modified subjects and animals. Major conclusions are the LLMs seem to qualify as authors that originally participate in discursive practices but do display only a structurally derivative form of communicative competence and fail to meet the status of communicative agents. In this sense, while the contribution of AI writing systems in public discourse and deliberation can support the process of mutual understanding within the community of speakers, the human actors involved in the development, use, and diffusion of these systems share a collective responsibility for the disclosure of AI authorship and verification and adjudication of validity claims.

This paper offers an analysis of a hitherto neglected text on insoluble propositions dating from the late XiVth century and puts it into perspective within the context of the contemporary debate concerning semantic paradoxes. The author of the text is the italian logician Peter of Mantua (d. 1399/1400). The treatise is relevant both from a theoretical and from a historical standpoint. By appealing to a distinction between two senses in which propositions are said to be true, it offers an unusual (...) solution to the paradox, but in a traditional spirit that contrasts a number of trends prevailing in the XiVth century. It also counts as a remarkable piece of evidence for the reconstruction of the reception of English logic in italy, as it is inspired by the views of John Wyclif. Three approaches addressing the Liar paradox (Albert of Saxony, William Heytesbury and a version of strong restrictionism) are first criticised by Peter of Mantua, before he presents his own alternative solution. The latter seems to have a prima facie intuitive justification, but is in fact acceptable only on a very restricted understanding, since its generalisation is subject to the so-called revenge problem.

Stumpf’s doctrine of the categories is of great importance for our understanding of his philosophy. This theme had been widely discussed among German thinkers after Kant; Brentano himself had repeatedly dealt with it since his early works. However, Stumpf considerably diverges from Brentano on this crucial philosophical topic. Although a systematic discussion can be found only in Stumpf’s posthumous Erkenntnislehre, his core ideas on the categories can be traced to his early work on space of 1873. In fact, Stumpf claims (...) that the peculiar relationship between extension and color is analogous to the relationship that holds between substance and accidents. Thus, like any other category, substance empirically stems from perception. Sensory experience, for Stumpf, is made up of perceptual wholes, whose attributes are typically bound to each other, rather than separately given in bundles, as Hume and other associationists used to assume. Thus, the achievements of Stumpf’s holist psychology effectively contributes a solution to this classic metaphysical problem. (shrink)

On an influential line of thinking tracing back to Ramsey, conditionals are closely linked to the attitude of supposition. When applied to counterfactuals, this view suggests a subjunctive version of the so-called Ramsey test: the probability of a counterfactual If A, would B ought to be equivalent to the probability of B, under the subjunctive supposition that A. I present a collapse result for any view that endorses the subjunctive version of the Ramsey test. Starting from plausible assumptions, the result (...) shows that one’s rational credence in a would-counterfactual and in the corresponding might-counterfactual have to be identical. (shrink)

The period from 1900 to 1935 was particularly fruitful and important for the development of logic and logical metatheory. This survey is organized along eight "itineraries" concentrating on historically and conceptually linked strands in this development. Itinerary I deals with the evolution of conceptions of axiomatics. Itinerary II centers on the logical work of Bertrand Russell. Itinerary III presents the development of set theory from Zermelo onward. Itinerary IV discusses the contributions of the algebra of logic tradition, in particular, Löwenheim (...) and Skolem. Itinerary V surveys the work in logic connected to the Hilbert school, and itinerary V deals specifically with consistency proofs and metamathematics, including the incompleteness theorems. Itinerary VII traces the development of intuitionistic and many-valued logics. Itinerary VIII surveys the development of semantical notions from the early work on axiomatics up to Tarski's work on truth. (shrink)

Recent developments in generalized probability theory have renewed a debate about whether regularity (i.e., the constraint that only logical contradictions get assigned probability 0) should be a necessary feature of both chances and credences. Crucial to this debate, however, are some mathematical facts regarding the interplay between the existence of regular generalized probability measures and various cardinality assumptions. We improve on several known results in the literature regarding the existence of regular generalized probability measures. In particular, we give necessary and (...) sufficient conditions for the existence of regular generalized probability measures defined on the whole powerset of any sample space. (shrink)

This essay is about the Wolfgang Köhler’s philosophical ideas expressed in his The Place of Value in a World of Facts of 1938. Köhler, who strongly supports a scientific world view, considers the question as to whether science is able to cope with human values, besides natural facts. Relying upon phenomenological analyses, and on his previous researches in natural philosophy, Köhler introduces his doctrine of “epistemological dualism”. From a historical point of view, this theory exhibits some similarity with the philosophical (...) ideas expressed by Köhler’s Berlin mentor Carl Stumpf. It is argued that Köhler’s epistemological dualism actually supports ontological monism and aims at offering a unified view of natural facts and human values. (shrink)

This essay focuses on the relation between man and the world in Kant’s anthropology. Within Baumgarten’s Metaphysica, used as a manual by Kant for his lessons, empirical psychology is situated between cosmology and rational psychology. However, this view is untenable for Kant, at least after the first Critique. Consequently, whereas Baumgarten explains, for instance, obscure ideas referring to the bodily position in the world, Kant’s pragmatic approach excludes this. Yet, the concept of «Welt» retains paramount importance within Kant’s Anthropology. The (...) two parts of the work are thus harmonically linked: the first offers an account of a largely pathological human psychology; the second a way out of the pathology through the construction of a social and historical human world. Accordingly, anthropology responds to the «Weltbegriff» of philosophy and helps to correct the deviations from the final rational destination of mankind. (shrink)

We aim to show that Kant’s theory of time is consistent by providing axioms whose models validate all synthetic a priori principles for time proposed in the Critique of Pure Reason. In this paper we focus on the distinction between time as form of intuition and time as formal intuition, for which Kant’s own explanations are all too brief. We provide axioms that allow us to construct ‘time as formal intuition’ as a pair of continua, corresponding to time as ‘inner (...) sense’ and the external representation of time as a line Both continua are replete with infinitesimals, which we use to elucidate an enigmatic discussion of ‘rest’ in the Metaphysical foundations of natural science. Our main formal tools are Alexandroff topologies, inverse systems and the ring of dual numbers. (shrink)

In this paper I shall discuss the relationship between the two known Arabic translations of Aristotle’s Posterior Analytics and Avicenna’s Kitāb al-Burhān. I shall argue that Avicenna relies on both (1) Abū Bishr Mattā’s translation and (2) the anonymous translation used by Averroes in the Long Commentary as well as in the Middle Commentary (and also indirectly preserved by Gerard of Cremona’s Latin translation of Aristotle’s work). Although, generally speaking, the problem is relevant to the history of the transmission of (...) the Posterior Analytics from Greek through Syriac into Arabic, I do not intend to give a systematic presentation of the historical setting in which Aristotle’s work became readily available to the Arabo-Islamic culture. My aim here is rather to isolate and discuss some pieces of evidence concerning the texts that seem to have been available to Avicenna. In addition to that, I shall also provide evidence concerning the relationship with the Greek commentary tradition (in particular Philoponus and Themistius) that is likely to have influenced Avicenna in his discussion of Aristotle’s theory of demonstration and scientific knowledge.

This essay addresses the attitude of some leading Neo-Kantian philosophers toward scientific psychology and psychophysics. Early influential figures like Friedrich A. Lange counted Gustav T. Fechner’s psychophysical law among their allies in the rehabilitation of the Kantian standpoint. Later on, however, Neo-Kantian philosophers firmly rejected psychological measurement as a whole and harshly criticized the methods adopted by several psychologists of their time. For example, the Marburg mathematician and philosopher August Stadler reduced the validity of Fechner’s law to the mere physiological (...) sphere, and Hermann Cohen conceived the application of mathematical integration to human sensations as an inane enterprise.

In this essay I analyze Kant's concept of character in the light of the concept of nature adopted in Kant's Pragmatic anthropology. In the Preface, Kant contrasts mechanical nature with freedom and opts for a pragmatic, rather than a physiological anthropology. In the Anthropological characteristics, however, Kant introduces his teleological concept of nature. Accordingly, he defends the view that there is no basic contrast between the purpose of nature (in the latter sense) and human freedom.

Suppose that you're certain that a certain sentence, e.g. "Frida is tall", lacks a determinate truth value. What cognitive attitude should you take towards it—reject it, suspend judgment, or what else? We show that, by adopting a seemingly plausible principle connecting credence in A and Determinately A, we can prove a very implausible answer to this question: i.e., all indeterminate claims should be assigned credence zero. The result is striking similar to so-called triviality results in the literature on modals and (...) conditionals. (shrink)

The critic of substance immobility through negation constitutes the starting point of the ‘voyage of discovery’ of Hegel’s Phänomenologie des Geistes, in which mind and body experiences are considered in terms of mutual recognition, without denying the subjectivity. In this article I am discussing some aspects of Hegel’s philosophy of spirit after Nietzsche’s ‘experimentalism’ and Dennett’s theory of mind, in order to articulate, through Bergson, two fundamental reasons. The first concerns the subject and the dramatic awareness of its constitutional temporality (...) and, at the same time, the possibility to transcend the limit of ‘here’ and ‘now’. On this basis, the second regards the indefensibility of nihilism, because, thanks to consciousness and its continuous activity, the temporal subject, from Hegel to Bergson, persists as a ‘dark side’, in which a constant ‘overcoming’ (élan) of an implicitly normative and essentially social practice takes place.

Peter Damian’s epistle 28, usually called Dominus vobiscum, shows a complex theological discussion. In fact, the author intertwines different subjects: the reform of the Church, the exaltation of monasticism, and, in particular, the primacy of the eremitical life. However, what is central in Peter Damian’s discourse is the Eucharistic sacrament, which the author considers from the standpoint of a theological sensitivity centered on the liturgical dimension of the celebration and on its spiritual and religious value. This contribution analyses Peter Damian’s (...) treatment of the Eucharistic sacrament, placing it in the historical-theological and doctrinal context of the disputes on the sacrament that animated the Church since the mid-eleventh century.

Many recent theories of epistemic discourse exploit an informational notion of consequence, i.e. a notion that defines entailment as preservation of support by an information state. This paper investigates how informational consequence fits with probabilistic reasoning. I raise two problems. First, all informational inferences that are not also classical inferences are, intuitively, probabilistically invalid. Second, all these inferences can be exploited, in a systematic way, to generate triviality results. The informational theorist is left with two options, both of them radical: (...) they can either deny that epistemic modal claims have probability at all, or they can move to a nonstandard probability theory.

Many nineteenth-century psychologists assume that the measurement of psychic intensity is a prerequisite to the development of a truly scientific psychology. In the first edition of the Psychology from an empirical point of view, Brentano deals with this question. He assumes that all psychic phenomena admit of a certain intensity. Later on, Brentano retreats this doctrine and claims that only sensible phenomena admit of an intensity, whereas intellectual presentations do not. As a consequence, Brentano introduces a radical gap between sensible (...) and noetic consciousness. By contrast, Stumpf maintains a continuity between sensations and presentations. The main difference between them is the degree of their intensity. The essay provides a discussion and a comparison of the above mentioned points of view. (shrink)

We present in this paper a novel ontological theory of events whose central tenet is the Aristotelian distinction between the object that changes and the actual subject of change, which is what we call an individual quality. While in the Kimian tradition events are individuated by a triple ⟨ o, P, t ⟩, where o is an object, P a property, and t an interval of time, for us the simplest events are qualitative changes, individuated by a triple ⟨ o, (...) q, t ⟩, where q is an individual quality inhering in o or in one of its parts. Detaching the individuation of events from the property they exemplify results in a fine-grained theory that keeps metaphysics and semantics clearly separate, and lies between the multiplicative and the unitarian approaches. We discuss then the way language refers to events, observing that, in most cases, event descriptions refer to complex, cognitively relevant clusters of co-occurring qualitative changes, which exhibit a synchronic structure depending on the way they are described. Contra Bennett, who famously argued that the semantics of event names ultimately depends on “local context and unprincipled intuitions”, we show how the lexicon provides systematic principles for individuating such clusters and classifying them into kinds. Finally, we address some open challenges in the semantics of locative and manner modifiers. (shrink)

Recent scholarship on climate and conflict has increasingly examined the dynamic relationship between environmental scarcities and geopolitical tensions. Overall, climate-related shocks often lead to escalated disputes over natural resources, thus positioning climate hazards not only as an environmental issue but also as a catalyst that intensifies existing geopolitical and social frictions. The discourse on climate and conflict has mostly centred on its direct effects on natural resources and environmental conditions. However, its role in precipitating conflicts underscores the critical need to (...) incorporate climate considerations within broader security and policy frameworks. In recent decades, one of the most compelling developments in this field is the inclusion of environmental issues within the security paradigm. Environmental degradation, global warming, and climate change are now recognized as critical threats that transcend national borders, impacting personal, national, and international security . These factors have broadened our comprehension of the relationships among environmental transformation, conflict, and vulnerability, and have highlighted the importance of conservation and sustainable development in fostering peace, stability, and human security. Despite the increased attention on climate in conflict and security studies, the mechanisms through which an environmental catastrophe, or the threat of it, gets securitized in conflict remain under investigated. Understanding how these threats are framed and leveraged by conflicting parties can provide critical insights into the intersection of environmental risks and geopolitical strategies, thereby enriching the discourse on environmental security and conflict dynamics. Most case studies focus on the securitization of natural resources, such as water in the Nile and Indus basins, concentrating on resource scarcity rather than potential catastrophes. Additionally, research on the Israeli-Palestinian conflict and domestic politics in the United Kingdom and the Netherlands shows how framing environmental threats as national security issues can influence power dynamics and foster global action. However, these cases suggest that previous research has predominantly investigated how states strategically employ environmental narratives within the framework of national security for political and economic advantages, often in contexts removed from direct conflict scenarios. Moreover, much of the discussion on environmental securitization has focused on state-centric perspectives and inter-state conflicts. This emphasis on state actions, both in domestic and international arenas, has left a significant gap concerning the weaponization of environmental threats by non-state actors within ongoing conflicts. In that sense, the contribution of my thesis is twofold. First, it analyzes the weaponization of a looming environmental catastrophe within a conflict setting. Second, it focuses on a case where non-state actors, specifically the Houthis, are primary securitization actors. More specifically, my thesis addresses the existing gap in the literature by analysing the case of the FSO Safer, a deteriorating oil storage tanker moored off the coast of Yemen. Before the United Nations’ successful offloading plan, the tanker held over one million barrels of crude oil, posing a significant risk of massive ecological and economic damage due to its poor condition and lack of maintenance since the onset of the Yemeni conflict. Despite the imminent threat of an ecological disaster, the conflicting parties in Yemen – the Houthis and the internationally recognized government – have used the Safer as a bargaining chip rather than prioritizing immediate remedial action. This has put the entire region in a state of suspense, with the potential for disastrous oil leakage that could impact the Red Sea's marine ecosystems and the broader geopolitical stability. The FSO Safer crisis has directly inspired the research question of this study, highlighting the need to understand the strategic use of environmental threats in geopolitical conflicts. This crisis vividly illustrates how impending ecological disasters are not solely managed as environmental or humanitarian issues but are intricately woven into the fabric of international security and conflict negotiation strategies. It prompts critical inquiries into how and why such existential threats are leveraged by involved parties to advance their geopolitical agendas. Therefore, the research question formulated for this study is: How are environmental threats utilized as strategic tools in geopolitical conflicts? (shrink)

When one visually hallucinates, the object of one’s hallucination is not before one’s eyes. On the standard view, that is because the object of hallucination does not exist, and so is not anywhere. Many different defenses of the standard view are on offer; each have problems. This paper defends the view that there is always an object of hallucination—a physical object, sometimes with spatiotemporally scattered parts.

Heinrich Behmann (1891-1970) obtained his Habilitation under David Hilbert in Göttingen in 1921 with a thesis on the decision problem. In his thesis, he solved - independently of Löwenheim and Skolem's earlier work - the decision problem for monadic second-order logic in a framework that combined elements of the algebra of logic and the newer axiomatic approach to logic then being developed in Göttingen. In a talk given in 1921, he outlined this solution, but also presented important programmatic remarks on (...) the significance of the decision problem and of decision procedures more generally.

Can taxation and the redistribution of wealth through the welfare state be conceived as a modern system of circulation of the gift? But once such a gift is institutionalized, regulated and sanctioned through legal mechanisms, does it not risk being perverted or corrupted, and/or not leaving room for genuinely altruistic motives? What is more: if the market’s utilitarian logic can corrupt or ‘crowd out’ altruistic feelings or motivations, what makes us think that the welfare state cannot also be a source (...) of corruption? To explain the standard answers to the abovementioned questions as well as their implications I will first re-examine two opposing positions assumed here as paradigmatic examples of other similar positions: on the one hand, Titmuss’s work and the never-ending debate about it; on the other, Godbout’s position, in-so-far as it shows how Titmuss’s arguments can easily be turned upside down. I will then introduce and reinterpret Einaudi’s “critical point” theory as a more complex and richer anthropological explanation of the problems and answers considered herein. Through the analysis of these paradigmatic positions I will develop two interrelated arguments. 1) The way these problems are posed as well as the standard answers to them are: a) subject to fallacies: the dichotomy fallacy and the fallacy of composition; b) too reductive and simplistic: we should at least try to clarify what kind of ‘gift’ or ‘corruption’ we are thinking about, and who or what the ‘giver’, the ‘corrupter’, the ‘receiver’ and/or the ‘corrupted’ party are. 2) The answers to these problems cannot be found by merely following a theoretical approach, nor can they be merely based on empirical evidence; instead, they need to take into account the forever troublesome, ambiguous and unpredictable matter of human freedom.

The aim of this article is to shed light on an understudied aspect of Giordano Bruno's intellectual biography, namely, his career as a mathematical practitioner. Early interpreters, especially, have criticized Bruno's mathematics for being “outdated” or too “concrete”. However, thanks to developments in the study of early modern mathematics and the rediscovery of Bruno's first mathematical writings (four dialogues on Fabrizio's Mordente proportional compass), we are in a position to better understand Bruno's mathematics. In particular, this article aims to reopen (...) the question of whether Bruno anticipated the concept of infinitesimal quantity. It does so by providing an analysis of the dialogues on Mordente's compass and of the historical circumstances under which those dialogues were written. (shrink)

This paper develops an information-sensitive theory of the semantics and probability of conditionals and statements involving epistemic modals. The theory validates a number of principles linking probability and modality, including the principle that the probability of a conditional If A, then C equals the probability of C, updated with A. The theory avoids so-called triviality results, which are standardly taken to show that principles of this sort cannot be validated. To achieve this, we deny that rational agents update their credences (...) via conditionalization. We offer a new rule of update, Hyperconditionalization, which agrees with Conditionalization whenever nonmodal statements are at stake but differs for modal and conditional sentences. (shrink)

At the turn of the seventeenth century, Bruno and Cavalieri independently developed two theories, central to which was the concept of the geometrical indivisible. The introduction of indivisibles had significant implications for geometry – especially in the case of Cavalieri, for whom indivisibles provided a forerunner of the calculus. But how did this event occur? What can we learn from the fact that two theories of indivisibles arose at about the same time? These are the questions addressed in this paper. (...) Relying on the methodology of “historical epistemology”, this paper asserts that the similarities and differences between the theories of Bruno and Cavalieri can be explained in terms of “shared knowledge”. The paper shows that the idea – on which both Bruno and Cavalieri build – that geometrical objects are generated by motion was part of the mathematical culture of the time. Tracing this idea back to its Pythagorean origins thus sheds light on the relationship between motion and continuum in mathematics. (shrink)

The paper examines Posterior Analytics II 11, 94a20-36 and makes three points. (1) The confusing formula ‘given what things, is it necessary for this to be’ [τίνων ὄντων ἀνάγκη τοῦτ᾿ εἶναι] at a21-22 introduces material cause, not syllogistic necessity. (2) When biological material necessitation is the only causal factor, Aristotle is reluctant to formalize it in syllogistic terms, and this helps to explain why, in II 11, he turns to geometry in order to illustrate a kind of material cause that (...) can be expressed as the middle term of an explanatory syllogism. (3) If geometrical proof is viewed as a complex construction built on simpler constructions, it can in effect be described as a case of purely material constitution. (shrink)

This introduction explains the reasons behind this Special issue and discuss the organization and content of it. The difficulty of a genuine dialogue and understanding between economics, law and humanities, seems to be due not only to the fragmentation of reflections on man, but to a real ‘conflict of anthropologies’. What kind of conceptions of man and human values are presupposed by and / or privileged by economics, law, economic approaches to law and social sciences? How and when do these (...) conceptions come into conflict within and between disciplines? How do these conceptions of man and his values influence the conceptions of economics, law and institutions, and vice versa, how do these last conceptions influence the former? What are the normative, regulatory and practical implications of assuming an anthropological and / or axiological perspective instead of another? This Special issue aims at exploring the possibility of finding a common ground for discussion between economics, law and humanities, through the analysis and comparison of both the conceptions of man, human action and values assumed by economics, law and humanities, and their normative implications. The contributions to this Special issue and its organization are outlined at the end of this introduction. (shrink)

The paper aims to address the following two questions: what kind of discourse is that which attempt to found or defend the autonomy or the boundaries of a discipline? Why do such discourses tend to turn into normative, dogmatic-excommunicating discourses between disciplines, schools or scholars? I will argue that an adequate answer may be found if we conceive disciplines as dogmatics, where such discourses often take the form of a discourse on the foundation of a discipline, a foundation in the (...) name of which the scholar speaks and with which he/she entertains an identity relationship. To this purpose I will re-examine the methodological discourses of (and debates between) Pareto, Croce and Einaudi on the demarcation issue between philosophy, economics and value-judgments as highly instructive to understand such issues.

In this essay I intend to analyze the issue of good government in the works of Adam Smith, the importance of which seems to have not received due attention. The reconstruction is driven by three hermeneutical hypotheses concerning the role played by the idea of good government in the development of Smith's speculation: 1) the «good government» has a synthetic character, holding together the different aspects – moral, legal, economic and political – of his reflection; 2) it emerges against the (...) backdrop of the first acquisitions of the Theory of Moral Sentiments about the ‘mediating’ role of the middle class, and especially during the reflection that goes from the Lectures on Jurisprudence to the Wealth of Nations, and then feeds back into the subsequent rewritings of the Theory; 3) From the moment the «good government» appears, it becomes a descriptive and prescriptive idea of the social order. In the conclusions I will show how these hermeneutical hypotheses might have implications in the history of political, legal and economic thought. (shrink)
