In European culture the sacred and the secular have existed in a dialectical relationship. Prodi sees the fifteenth-century crisis of Christianity as opening up three paths that eroded this dualism and tended towards modernity: civic-republican religion, sacred monarchy, and the territorial churches. Important counter-forces, which sought to maintain dualism, included the Roman-Tridentine Compromise, and those forms of Radical Christianity which rejected confessionalisation outright. During the Eighteenth Century, all these phenomena tended to contribute to one of two tendencies: towards civic (...) religion, or towards political religion. The former preserved a distinction between conscience and law; the latter comprised a state religion which sought to perfect all of human nature. It was civic religion which become embodied in the early USA, alienating God from worldly power, but leaving him as the guarantor of agreements between humans. Back in Europe, Prodi tracks the relationship between the Catholic Church and the new national states. He then turns to the political religions of the Twentieth Century. Prodi concludes by emphasising that this dualism of sacred and secular power lay at the centre of Western modernity, and expresses his fears about the collapse of civic religion into political religion, especially in the USA.

Il presente intervento costituisce soltanto un breve introduzione, come richiamo delle ragioni che hanno portato a questo Exploratory Workshop, nel ricordo delle riunioni che lo hanno preceduto sino all’incontro qui a Bologna il 15 febbraio 2011 e a quello di Nijmegen nell’autunno del 2011.1 Non si tratta infatti di un convegno conclusivo ma soltanto di una tappa del cammino che il gruppo di lavoro si era prefisso. Il tema formulato dall’inizio era quello di studiare il formarsi delle identità collettive e (...) dei modelli di vita nel mondo rimasto fedele alla Chiesa di Roma, nel periodo della Riforma e della frattura religiosa sino al definirsi definitivo degli schieramenti confessionali: “Pluralism and Identity..

Purpose: This article investigates the emergence of subsystems in societies as a solution to the double contingency problem. Context: There are two underlying paradigms: one is radical constructivism in the sense that perturbations are at the centre of the self-organising processes; the other is Luhmann’s double contingency problem, where agents learn anticipations from each other. Approach: Central to our investigation is a computer simulation where we place agents into an arena. These agents can learn to (a) collect food and/or (b) (...) steal food from other agents. In order to analyse subsystem formation, we investigate whether agents use both behaviours or just one of these, which is equivalent to determining the number of self-referential loops. This is detected with a novel measure that we call “prediction utilisation.” Results: During the simulation, symmetry breaking is observed. The system of agents divides itself up into two subsystems: one where agents just collect food and another one where agents just steal food from other agents. The ratio between these two populations is determined by the amount of food available. Key words: Social systems, constructivist paradigm, cybernetics, double contingency, symmetry breaking, emergence. (shrink)

This essay analyzes the work of Paolo Prodi (1932–2016), which is characterised by a constant reflection on secularisation. As a democratic Catholic, he explored the relationship between the Roman Church and the modern world starting from the Council of Trent and from the dual figure of the pope as a temporal ruler and spiritual guide. His original contribution concerned the conflict between law and conscience: a problem that led him to design a triptych of books on the foundations (...) of the western world. He was influenced not only by Verfassungsgeschichte (German constitutional history), but also by Harold Berman. If for Weber the modern world was born from the Reformation, for Berman it was the ‘Gregorian revolution’ that changed the fate of Latin Europe. For Prodi, too, the medieval conflict between canon and civil law introduced a peculiar structure in Europe that would last until the triumph of the nation states and the so-called ‘political religions’. In his three books (the first dedicated to the oath, the second to justice, the last to economics), Prodi placed at the centre of his analysis the notion of forum; the history of moral theology and casuistry and the relationship between penitence and justice.

This paper presents key elements of Paolo Prodi´s historiagraphic theory that allow us to include him in the contemporary debate on the rol of religion and morality within democratic societies. The text is developed in three moments. First, we will briefly describe the aforementioned debate. Second, we will present the theorical elements found in Prodi’s works which are more relevant for the topic discussed. Finally, we will offer some critical comments in order to present what, for us, (...) is still an open discussion. (shrink)

Did early modern European states make themselves sacred? The historian Paolo Prodi insisted that they did, whereas for the philosopher Giorgio Agamben sacred and secular power were so indistinguishable that the question was moot. This group of articles seeks to explain and explore the approaches of these two accomplished Italian scholars to the problem of early modern sacralisation. This introduction reviews the context in which Prodi and Agamben worked, sketches brief biographies, and describes the arguments that they (...) advanced which are most relevant to early modern history. Their work emerged from the debate on secularisation in the German-speaking lands, the confessionalisation thesis as it was advanced by German historians of Reformation, Counter-Reformation, and Catholic Reform, and twentieth-century Catholic thought about the relationship between religion and totalitarian states. Both Prodi and Agamben belonged to traditions that sat at an angle to the liberalism that underpins historical and philosophical thought in the English-speaking world. (shrink)

This paper argues that an exchange between Paolo Prodi and Giorgio Agamben on the role of the sacred in European constitutional history can inform the study of early modern history of political thought. Prodi, in his history of the sworn oath (sacramentum), and Agamben, in his history of the curse (sacer esto) and the accursed, or outlaw (homo sacer), explored how these sacred threats and promises, though not purely legal expressions themselves, underpinned the legal order. Through a (...) study of three sixteenth-century legal humanists’ views of the Roman laws concerning these sacred oaths and curses (the sacratae leges), this paper describes a similar interest in exploring the connection between the sacred and the legal order. It concludes that the idea of the commonwealth in the sixteenth century was a complex of legal and para-legal techniques, symbols, and structures in addition to the more frequently studied restoration of classical virtue theory. This paper also provides an edition and translation of Guillaume Budé's discussion of the Roman law of banishment [D. 48.19.2], which was the first legal commentary to assemble the materials relating to the homo sacer.

This book is a continuation of Giorgio Agamben's investigation of political theory, which began with the highly influential volume _Homo Sacer: Sovereign Power and Bare Life_. Having already traced the roots of the idea of sovereignty, sacredness, and economy, he now turns to a perhaps unlikely topic: the concept of the oath. Following the Italian scholar Paolo Prodi, Agamben sees the oath as foundational for Western politics and undertakes an exploration of the roots of the phenomenon of the (...) oath in human experience. He rejects the common idea that the oath finds its origin in religion, arguing instead that the oath points toward a particular response to the experience of language, a response that gave birth to both religion and law as we now know them. This book is important not only for readers of Agamben or of continental philosophy more broadly, but for anyone interested in questions relating to the relationships among religion, law, and language.

The period, from the middle of the fifteenth century, and in particular the fruition of the Franciscan Observance under the leadership of Bernardino of Siena, John of Capistrano and James of the Marches, through the end of the Council of Trent , lasts about a century. It is a century that has recently been the focus of much attention in our research group.2 The hypothesis in this essay is that this century was marked more by continuities than fractures, and in (...) which many problems came to the fore. Therefore, this was a period of instability but also of great vitality:3 “not a starting point, but the climax,” as Paolo Prodi wrote.4The booklet of Paolo Giustiniani and Pietro Quirini, the so-called Libellus ad ..

Open peer commentary on the article “Subsystem Formation Driven by Double Contingency” by Bernd Porr & Paolo Di Prodi. Upshot: By analyzing Porr and Di Prodi’s model for addressing the double contingency problem, I try to take a step further by questioning the importance and implications of the loop concept in the constructivist approach.

Open peer commentary on the article “Subsystem Formation Driven by Double Contingency” by Bernd Porr & Paolo Di Prodi. Upshot: Agents that learn from perturbations of closed control loops are considered constructivist by virtue of the fact that their input (the perturbation) does not convey ontological information about the environment. That is, they learn by actively experiencing their environment through interaction, as opposed to learning by registering directly input data characterizing the environment. Generalizing this idea, the notion of (...) learning by experiencing provides a broader conceptual framework than cybernetic control theory for studying the double contingency problem, and may yield more progress in constructivist agent design.

Open peer commentary on the article “Subsystem Formation Driven by Double Contingency” by Bernd Porr & Paolo Di Prodi. Upshot: There is merit to the continuous-signal-space homeostatic viewpoint on subsystem formation presented by Bernd Porr and Paolo Di Prodi; many of their ideas also align well with a heterostatic constructivist perspective, and specifically developments in the field of reinforcement learning. This commentary therefore aims to identify and clarify some of the linkages made by the authors, and (...) highlight ways in which these interdisciplinary connections may be leveraged to enable future progress.

Open peer commentary on the article “Subsystem Formation Driven by Double Contingency” by Bernd Porr & Paolo Di Prodi. Upshot: I acknowledge the value of Porr & Di Prodi’s piece for simulating Luhmann’s key process of subsystem formation and exploring how the concepts of “differentiation” and “binary code” relate to their model.

The COVID-19 pandemic is an unprecedented event entailing long-term consequences on population health and welfare. Those who contracted the coronavirus may have suffered from both physical and mental health issues that unfold the need for tailored intervention strategies. Hence, our study aims to investigate the psychological and social consequences of COVID-19 on a sample of 86 participants, encompassing 43 patients recruited from Bari University Hospital, 19 of whom were hospitalized due to the disease. The remaining 43 were individuals not fallen (...) ill with COVID-19 to date. The investigation yielded significant gender differences in post-traumatic stress symptoms, depression, and representation of interpersonal distance, evaluated through the IES-R, the BDI-II, and the IVAS task, respectively. This pattern of results was not replicated in the control group. In general, participants who reported having experienced the most intense post-traumatic symptoms also presented a greater mood deflection and, more specifically, within the clinical group women obtained the highest scores on both scales. Women reported higher IES-R and BDI-II scores compared to men, that could indicate that women who have contracted COVID-19 are more exposed to post-traumatic and depressive symptoms. Our results also showed a significant effect of COVID-19 on IPD with a tendency of disease-experienced individuals to increase their preferred IPD from adults, children, and elderly people. Regarding gender differences in mood and proxemic behavior, a correlation between depressive symptoms and probable PTSD and a further correlation between probable PTSD and greater IPD were found in women from both clinical and control group. Overall, these findings might contribute to a better understanding of gender-based implications of the current pandemic on mental health, also leading to the development of integrated yet personalized intervention strategies.

Neuroeconomics, neuromarketing, neuroaesthetics, and neurotheology are just a few of the novel disciplines that have been inspired by a combination of ancient knowledge along with recent discoveries about how the human brain works.This fascinating and thought provoking new book critically questions our love affair with brain imaging.

In the last decades, Systems Biology (including cancer research) has been driven by technology, statistical modelling and bioinformatics. In this paper we try to bring biological and philosophical thinking back. We thus aim at making diferent traditions of thought compatible: (a) causality in epidemiology and in philosophical theorizing—notably, the “sufcient-component-cause framework” and the “mark transmission” approach; (b) new acquisitions about disease pathogenesis, e.g. the “branched model” in cancer, and the role of biomarkers in this process; (c) the burgeoning of omics (...) research, with a large number of “signals” and of associations that need to be interpreted. In the paper we summarize frst the current views on carcinogenesis, and then explore the relevance of current philosophical interpretations of “cancer causes”. We try to ofer a unifying framework to incorporate biomarkers and omic data into causal models, referring to a position called “evidential pluralism”. According to this view, causal reasoning is based on both “evidence of diference-making” (e.g. associations) and on “evidence of underlying biological mechanisms”. We conceptualize the way scientists detect and trace signals in terms of information transmission, which is a generalization of the mark transmission theory developed by philosopher Wesley Salmon. Our approach is capable of helping us conceptualize how heterogeneous factors such as micro and macro-biological and psycho-social—are causally linked. This is important not only to understand cancer etiology, but also to design public health policies that target the right causal factors at the macro-level. (shrink)

An algebraization of the notion of topology has been proposed more than 70 years ago in a classical paper by McKinsey and Tarski, leading to an area of research still active today, with connections to algebra, geometry, logic and many applications, in particular, to modal logics. In McKinsey and Tarski’s setting the model theoretical notion of homomorphism does not correspond to the notion of continuity. We notice that the two notions correspond if instead we consider a preorder relation \( \sqsubseteq (...) \) defined by $a \sqsubseteq b$ if _a_ is contained in the topological closure of _b_, for _a_, _b_ subsets of some topological space. A _specialization poset_ is a partially ordered set endowed with a further coarser preorder relation $\sqsubseteq$. We show that every specialization poset can be embedded in the specialization poset naturally associated to some topological space, where the order relation corresponds to set-theoretical inclusion. Specialization semilattices are defined in an analogous way and the corresponding embedding theorem is proved. Specialization semilattices have the amalgamation property. Some basic topological facts and notions are recovered in this apparently very weak setting. The interest of these structures arises from the fact that they also occur in many rather disparate contexts, even far removed from topology. (shrink)

Quine is one of the most influential of contemporary philosophers, whose work has ranged broadly across a great number of topics and issues in a career spanning some fifty years. In this collection a group of distinguished philosophers offer a sustained critical evaluation of the full range of Quine's writings. Amongst the topics addressed are interpretation, epistemology, ontology, modality, and mathematical truth. This collection will certainly influence all future discussion of Quine. The contributors include: George Boolos, H-N. Castaneda, Donald Davidson, (...) Umberto Eco, Dagfinn Follesdal, James Higginbotham, Charles Parsons, Hilary Putnam, Barry Stroud, and Bas van Fraassen. However, Quine is given the last word, responding to the essays in the final contribution. (shrink)

The notion of «the common good», which is crucial for understanding humankind and society, is not immediately obvious. It is, moreover, widely understood and used according to meanings that are irreconcilable and internally contradictory. The essay, after distinguishing between a notional exposition and the possibility of analysing the common good as the constitutive profile of human reality, deepens the structure and sense of order of life in association. This order, inasmuch as it takes shape and consistency through the free and (...) generous cooperation among individuals, may be described as the integrating moment of the common good, the nucleus of society inasmuch as expression of the original social reality of humanity. The common good is constituted through the participation of individuals and - together, circularly and progressively - opens itself up as the place of their possible realization. In this way the common good is the inescapable key to understanding the mystery of our social and historical condition. (shrink)

Logical forgetting is NP-complete as a decision problem even in the simple case of propositional Horn formulae, and may exponentially increase their size. A way to forget is to replace each variable to forget with the body of each clause whose head is the variable. It takes polynomial time in the single-head case: each variable is the head of at most a clause. Some formulae are not single-head but can be made so to simplify forgetting. They are called single-head equivalent. (...) The first contribution of this article is the study of a semantical characterization of single-head equivalence. Two necessary conditions are given. They are sufficient when the formula is interequivalent, that is, the formula makes two sets of variables equivalent only if they are also equivalent to their intersection. All acyclic formulae are interequivalent. The second contribution of this article is an incomplete algorithm for turning a formula single-head. In case of success, forgetting becomes possible in polynomial time and produces a polynomial-size formula, none of which is otherwise guaranteed. The algorithm is complete on interequivalent formulae. (shrink)

We devise exact conditions under which a join semilattice with a weak contact relation can be semilattice embedded into a Boolean algebra with an overlap contact relation, equivalently, into a distributive lattice with additive contact relation. A similar characterization is proved with respect to Boolean algebras and distributive lattices with weak contact, not necessarily additive, nor overlap.

One of the complications of a clear evaluation of different positions called “realism” in metaphysics and ontology is discrepancy in terminology and variance of basic intuitions inherent this notion. I recommend a taxonomy that distinguishes three kinds of variance: variance in the sets of conditions for a philosophical position to be acknowledged as actual realism, variance in strength and variance in conceptual frameworks. Within this last case, I propose to differentiate realism in epistemology, in ontology, and in metaphysics, intersecting these (...) three variants with the local/global realism dichotomy. The taxonomy here provided aims at being meta-philosophical; expressive enough for a fine-grained articulation of different philosophical positions in the recent debate, including the question of metaphysical grounding; and impartial, with no need to be connected to the defense of one form or another of the philosophical positions called “realism.”.

Italian Abstract: Mosca, Ruffini ed Einaudi vennero da molti riconosciuti come “Maestri di libertà”, soprattutto in virtù della loro strenua difesa della libertà durante il consolidamento del regime fascista. In questo articolo miro a ricostruire l’idea di libertà che emerse nelle loro riflessioni in quel torno di tempo. Mostrerò come, al di là delle differenze tra la loro riflessione politica, giuridica ed economica, l’idea di libertà si sostanzi nell’intreccio tra le istituzioni fondamentali del liberalismo ottocentesco: mercato e società civile, opinione (...) pubblica e diritti di libertà. -/- English Abstract: Mosca, Ruffini and Einaudi were variously identified as "Masters of Freedom", particularly in light of their strong defense of freedom during the consolidation of the fascist regime. In this article I aim to reconstruct the idea of freedom that emerged in their reflections during that period. I will show how, beyond the differences between their political, legal and economic approach, the idea of freedom is entailed in the intertwining between the fundamental institutions of nineteenth-century liberalism: market and civil society, public opinion and rights of freedom.

The paper aims to describe the stakes of a Nietzschean influence on Deleuze's reflections on the transcendental and conversely to highlight the Deleuzian operation of politicising Nietzsche by ‘minorising’ him. In order to further understand such a complex relationship of becoming between Deleuze and Nietzsche, the first objective of the paper is to focus on active and reactive forces, which seem to be the core of this very relation. Thus, the paper suggests that micropolitics has its conditions of possibility in (...) the Nietzschean corpus and, in particular, in the symptomatology of decadence, resentment and nihilism. In this sense, now the title of the paper reveals its meaning: the whole Deleuzian operation could be summarised as the passage from the criticism and questioning of an image of Nietzsche ‘forbidden to minors’, typical of the interpretations of the first half of the twentieth century, to a becoming-minor of these very same Nietzschean concepts. It is precisely through such a becoming-minor that Nietzsche's diagnosis and concepts are translated in a political and emancipatory key, in order to give power to minorities. (shrink)
