This article claims that the study of irregular migration may be a strategic research material for the development of an adequate understanding of contemporary society. The field, however, suffers not only from a lack of reliable empirical data, but also from endemic undertheorizing. The article shows how the attempt to develop an understanding of irregular migration from within a general theory of modern society has positive consequences both for the clarification of the problems and for the design of research programs (...) able to deal adequately with the phenomena. Particularly, it is argued that a theory of modern society centered on its form of differentiation may help to clarify both the political dimension of contemporary international mobility, the variety of irregular statuses existing in the foreign population of receiving countries, and the condition of inclusion and exclusion of irregular migrants.

In this contribution I will retrace the main stages of my research on the objectification problem in quantum mechanics by highlighting some personal memories of my supervisor, the theoretical physicist Giovanni Morchio. The central aim of my MSc thesis was to ask whether the hypothesis of objectification, which is currently added to the formalism, is not, at least in one case, deducible from it and in particular from the dynamics of the temporal evolution. The case study we were looking for (...) had to: 1) represent a situation similar to that in which a macroscopic system such as a measurement apparatus, following interaction with a system, assumes a well-defined state (which or for example represents the fact that the result of a measurement is a particular value), i.e becomes objective 2) represent a fact in nature in which it is not clear whether its explanation can be derived from the formalism of quantum mechanics or whether a hypothesis of objectification is necessary for its explanation. Proving that such a fact can be deduced from the time evolution of quantum mechanics allowed us to conclude that there are cases in which the hypothesis of objectification is superfluous or, in other words, obtainable from the formalism.

In this chapter I shall address the question as to whether there exists a universal and atemporal justification for the claims made by a community that adopts a particular style of reasoning. I shall present a case study in which a claim made in the laboratory style of reasoning has no universal and atemporal justification. As I shall explain, Hacking justifies his belief that unobservable entities exist on the ground that they can be regularly manipulated by experimenters in order to (...) find out and produce various phenomena (experimental realism); he also maintains that no belief that our theories are true is required in order to be realist about unobservable entities. I shall argue that his justification is relative to the laboratory style of reasoning. Ultimately, from this case study I shall draw the important conclusion that the styles of reasoning project implies epistemic relativism. In the first part of this chapter, I shall analyse Hacking’s experimental realism in the light of the styles of reasoning project. I shall start by making these points: Hacking’s theory anti-realism denies the possibility of ranking styles of reasoning in terms of their capacity to explain phenomena; furthermore, Hacking is not successful in showing that his entity realism is justified for a community that does not adopt the laboratory style of reasoning. It will follow that the styles of reasoning project is in conflict with the claim that we know about unobservable entities. (shrink)

In this chapter I shall present two different notions of the concept of ‘ways of thinking’ named ‘style of reasoning’ and ‘epistemic virtue’, which have been proposed, respectively, by Ian Hacking and by Peter Galison and Lorraine Daston. To explain how the former characterizes the notion of style of reasoning, I shall reread his book The Emergence of Probability in terms of the notion of ‘statistical style of reasoning’ and Shapin and Schaffer’s Leviathan and the Air Pump in terms of (...) the notion of ‘laboratory style of reasoning’. My analysis will show that many points of Hacking’s styles project need to be developed in order to make his suggestions into a full-fledged theory. A salient point of my analysis will be that Hacking’s is another of the projects of historical epistemology that historicize Kant. I shall also show that there are substantial convergences between the styles project and Daston and Galison’s study on objectivity. Finally, following Williams’s account of truth and truthfulness, I shall argue that styles of reasoning are ways of telling the truth and ways of looking at the world. (shrink)

The analytical notion of ‘scientific style of reasoning’, introduced by Ian Hacking in the middle of the 1980s, has become widespread in the literature of the history and philosophy of science. However, scholars have rarely made explicit the philosophical assumptions and the research objectives underlying the notion of style: what are its philosophical roots? How does the notion of style fit into the area of research of historical epistemology? What does a comparison between Hacking’s project on styles of thinking and (...) other similar projects suggest? My aim in this paper is to answer these questions. Hacking has denied that his project of styles of thinking falls into the field of historical epistemology. I shall challenge his remark by tracing out the connections of the notion of style with historical epistemology and, more in general, with a tradition of thought born in France in the beginning of twentieth-century.

The analytical notions of ‘thought style’, ‘paradigm’, ‘episteme’ and ‘style of reasoning’ are some of the most popular frameworks in the history and philosophy of science. Although their proponents, Ludwik Fleck, Thomas Kuhn, Michel Foucault, and Ian Hacking, are all part of the same philosophical tradition that closely connects history and philosophy, the extent to which they share similar assumptions and objectives is still under debate. In the first part of the paper, I shall argue that, despite the fact that (...) these four thinkers disagree on certain assumptions, their frameworks have the same explanatory goal – to understand how objectivity is possible. I shall present this goal as a necessary element of a common project -- that of historicising Kant's a priori. In the second part of the paper, I shall make an instrumental use of the insights of these four thinkers to form a new model for studying objectivity. I shall also propose a layered diagram that allows the differences between the frameworks to be mapped, while acknowledging their similarities. This diagram will show that the frameworks of style of reasoning and episteme illuminate conditions of possibility that lie at a deeper level than those considered by thought styles and paradigm.

Dans la mythologie grecque, Prométhée - le 'prévoyant' - déroba le feu aux dieux et le transmit aux hommes. Zeus, courroucé par ce transfert technologique, condamna Prométhée à un châtiment itéré à l'identique, à l'infini, algorithmique. Le problème que pose l'ancien mythe est celui des limites de la connaissance. En termes modernes, jusqu'à quel point pouvons-nous transformer la nature sans une connaissance des conséquences de nos actions sur elle? Cette question nous pousse à analyser les limites des sciences : à (...) une techno-science devenue toujours plus invasive, la science répond en se donnant à elle-même des limites"--Page 4 of cover.

This paper explores taste fragmentalism, a novel approach to matters of taste and faultless disagreement. The view is inspired by Kit Fine’s fragmentalism about time, according to which the temporal dimension can be constituted—in an absolute manner—by states that are pairwise incompatible, provided that they do not obtain together. In the present paper, we will apply this metaphysical framework to taste states. In our proposal, two incompatible taste states (such as the state of rhubarb’s being tasty and the state of (...) rhubarb’s being distasteful) can both constitute reality in an absolute manner, although no agent can have joint access to both states. We will then develop a formalised version of our view by means of an exact truthmaker semantics for taste assertions. Within this framework—we argue—our linguistic and inferential practices concerning cases of faultless disagreement are elegantly vindicated, thus suggesting that taste fragmentalism is worth of further consideration.

The question as to whether Ian Hacking’s project of scientific styles of thinking entails epistemic relativism has received considerable attention. However, scholars have never discussed it vis-à-vis Wittgenstein. This is unfortunate: not only is Wittgenstein the philosopher who, together with Foucault, has influenced Hacking the most, but he has also faced the same accusation of ‘relativism’. I shall explore the conceptual similarities and differences between Hacking’s notion of style of thinking and Wittgenstein’s conception of form of life. It is a (...) fact that whether or not the latter entails epistemic relativism is still a controversial question. From my comparative analysis, it will emerge that there are stronger reasons to conclude that Hacking’s notion of style leads to epistemic relativism than there are to reach the same conclusion in the case of Wittgenstein’s conception of form of life. This point will be at odds with the anti-relativistic stance that Hacking has taken in his more recent writings. (shrink)

The moving spotlight account (MS) is a view that combines an eternalist ontology and an A-theoretic metaphysics. The intuition underlying MS is that the present time is somehow privileged and experientially vivid, as if it were illuminated by a moving spotlight. According to MS-theorists, a key reason to prefer MS to B-theoretic eternalism is that our experience of time supports it. We argue that this is false. To this end, we formulate a new family of positions in the philosophy of (...) time, which differ from MS in that, intuitively, they admit a plurality of moving spotlights. We argue that these ‘deviant’ variants of MS cannot be dismissed as conceptually incoherent, and that they are as well-supported by our experience as is MS. One of these variants, however, is consistent with the B-theory. Thus, if our experience of time supports MS, then it supports the B-theory as well. (shrink)

Open futurism is the indeterministic position according to which the future is ‘open’, i.e., there is now no fact of the matter as to what future contingent events will actually obtain. Many open futurists hold a branching conception of time, in which a variety of possible futures exist. This paper introduces two challenges to branching-time open futurism, which are similar in spirit to a challenge posed by Fine to tense realism. The paper argues that, to address the new challenges, open (...) futurists must adopt an objective, non-perspectival notion of actuality and subscribe to an A-theoretic, dynamic conception of reality. Moreover, given a natural understanding of “actual future”, it is perfectly sensible for open futurists to hold that a unique, objectively actual future exists, contrary to a common assumption in the current debate. The paper also contends that recognising the existence of a unique actual future helps open futurists to avoid potential misconceptions. (shrink)

Artefacts do not always do what they are supposed to, due to a variety of reasons, including manufacturing problems, poor maintenance, and normal wear-and-tear. Since software is an artefact, it should be subject to malfunctioning in the same sense in which other artefacts can malfunction. Yet, whether software is on a par with other artefacts when it comes to malfunctioning crucially depends on the abstraction used in the analysis. We distinguish between “negative” and “positive” notions of malfunction. A negative malfunction, (...) or dysfunction, occurs when an artefact token either does not or cannot do what it is supposed to. A positive malfunction, or misfunction, occurs when an artefact token may do what is supposed to but, at least occasionally, it also yields some unintended and undesirable effects. We argue that software, understood as type, may misfunction in some limited sense, but cannot dysfunction. Accordingly, one should distinguish software from other technical artefacts, in view of their design that makes dysfunction impossible for the former, while possible for the latter. (shrink)

Célèbre traducteur et commentateur de Hegel, historien de la philosophie contemporaine, passeur de textes et de concepts, professeur et directeur de travaux universitaires, Jean Hyppolite (1906 - 1968) fut un vrai " protecteur de la nouveauté " et, partant, une figure essentielle au développement de la philosophie française du XXe siècle. Ce livre rassemble, avec les contributions de certains de ses anciens élèves les plus éminents (Badiou, Balibar, Macherey) et de chercheurs étrangers, nombre de ses écrits - dont son premier (...) et son dernier essai - restés inédits ou devenus indisponibles. Un entretien de 1965 entre Jean Hyppolite et Alain Badiou complète le livre. (shrink)

The notion of subject matter is a key concern of contemporary philosophy of language and logic. A central task for a theory of subject matter is to characterise the notion of sentential subject matter, that is, to assign to each sentence of a given language a subject matter that may count as its subject matter. In this paper, we elaborate upon David Lewis’ account of subject matter. Lewis’ proposal is simple and elegant but lacks a satisfactory characterisation of sentential subject (...) matter. Drawing on linguistic literature on focus and on the question under discussion, we offer a neo-Lewisian account of subject matter, which retains all the virtues of Lewis’ but also includes an attractive characterisation of sentential subject matter.

In this chapter I shall bring to the fore the family resemblances of the different notions of the concept of ‘ways of thinking’ that I have introduced in the previous chapter. For example, I shall compare Hacking’s styles project with Daston and Galison’s study on objectivity as well as with other projects such as Fleck’s, Kuhn’s and Foucault’s. Thanks to these comparative analyses, I shall identify points where all these projects support one another. I shall also provide a model for (...) studying objectivity that incorporates the notions of Fleck, Foucault, Kuhn and Hacking. Used together, these notions provide a more profound understanding of how objectivity emerges. Furthermore, I shall propose a layered diagram that maps the differences between the notions of thought style, episteme, paradigm and style of reasoning. Finally I shall highlight two philosophical issues, relativism and contingency, connected with the concept of ‘ways of thinking’ in all its different notions. I shall argue that this issue is particularly controversial in the case of Hacking’s notion. (shrink)

Das Buch enthält die Einführung in die Lektüre sowie den Textkommentar zu den der Analyse der Grundsätze der Modalität gewidmeten "Postulaten des empirischen Denkens überhaupt". Untersucht wird Kants gesamte Theorie der Modalbegriffe (Möglichkeit - Unmöglichkeit, Dasein - Nichtsein, Notwendigkeit - Zufälligkeit) seit Mitte der 1750er Jahre bis zur Kritik der reinen Vernunft. Die Postulate sind nach Kant nicht objektiv, sondern subjektiv-synthetisch: Der Gegenstand der Erfahrung, welcher zunächst anhand der objektiv-synthetischen Funktionen der Quantität, Qualität und Relation bestimmt wird, lässt sich nun (...) in seinem Verhältnis zum setzenden Subjekt betrachten. Die Postulate thematisieren jedoch nicht - hier liegt die konstitutive Charakteristik dieser synthetischen Urteile a priori - das Subjekt selbst, sondern das Objekt als solches und die Objektivität überhaupt. Wie diese Untersuchung zeigt, antwortet Kant erst hier - nicht in den viel diskutierten Deduktionskapiteln oder in den anderen Grundsatzkapiteln - auf die Frage "Was ist ein Objekt?" und bezieht zugleich Stellung gegenüber anderen philosophischen Theorien der Objektivität des 18. Jahrhunderts: Rationalismus, Empirismus, Idealismus, Skeptizismus. (shrink)

In this chapter, I shall consider a number of connections between various ideas of the theory of styles of reasoning and the issue of the contingency and inevitability of science. By ‘contingency issue’ it is meant the question as to whether the history of a particular branch of our science could have taken a different route and provided results incompatible with those of our actual science. Apart from Hacking’s recent comments, the discussions on the contingency issue have not involved the (...) notion of style of reasoning. I will fill this gap in the literature by drawing some important implications for the issue of contingency from the theory of styles of reasoning that I have developed so far. I shall address four fundamental questions. First of all, in the next section I shall discuss to which extent the emergence of styles of reasoning at a certain point of history is a contingent circumstance. In the following section I shall ask whether the endurance of styles of reasoning was inevitable by tackling the connected question as to why the styles are long lasting. Afterwards, I shall focus on the growth of knowledge by dealing with questions such as: if a certain style of reasoning continues to be employed and if Q is a ‘live question’, is science bound to converge on a single answer to Q? Finally, on the basis of my previous reflections I shall look into the question of the convergence of science in the long run. The answers to these questions will rely on some basic assumptions of the theory of style of reasoning and imply a picture of the evolution of sciences in which both contingency and inevitability play a key role.

Computing, today more than ever before, is a multi-faceted discipline which collates several methodologies, areas of interest, and approaches: mathematics, engineering, programming, and applications. Given its enormous impact on everyday life, it is essential that its debated origins are understood, and that its different foundations are explained. On the Foundations of Computing offers a comprehensive and critical overview of the birth and evolution of computing, and it presents some of the most important technical results and philosophical problems of the discipline, (...) combining both historical and systematic analyses. -/- The debates this text surveys are among the latest and most urgent ones: the crisis of foundations in mathematics and the birth of the decision problem, the nature of algorithms, the debates on computational artefacts and malfunctioning, and the analysis of computational experiments. By covering these topics, On the Foundations of Computing provides a much-needed resource to contextualize these foundational issues. -/- For practitioners, researchers, and students alike, a historical and philosophical approach such as what this volume offers becomes essential to understand the past of the discipline and to figure out the challenges of its future.
