This paper is an historical study of Tarski's methodology of deductive sciences (in which a logic S is identified with an operator Cn S, called the consequence operator, on a given set of expressions), from its appearance in 1930 to the end of the 1970s, focusing on the work done in the field by Roberto Magari, Piero Mangani and by some of their pupils between 1965 and 1974, and comparing it with the results achieved by Tarski and the (...) Polish school (Łoś, Suszko, Słupecki, Pogorzelski, Wójcicki). In the last section of the paper we will then compare these works with some recent developments in algebraic logic: this will lead to a better understanding of the results of the methodology of deductive science, but at the same time will show some intrinsic limits to such an approach to logic. Even if Magari's work on diagonizable algebras and universal algebra and Mangani's axiomatization of MV-algebras and results in model theory are rather famous, the articles on closure operators, published in the 1960s, are almost totally unknown outside Italy (mainly because of a linguistic limitation, the papers we analyse having been written and published in Italian). This paper aims to fill the gap in the literature and to enable the international community to get acquainted with this part of Italian logic. The same applies to some works published in Barcelona (in Catalan) at the end of the 1970s, analysed in the last section. (shrink)

Acts of civil disobedience, which imply the open violation of a legal directive, often result in the forceful imposition of a choice upon others (e.g. blockades). This is sometimes justifiable, within a democracy, in cases of ‘democratic deficit’, namely, when fundamental rights of an oppressed minority are at stake. In this article, I claim that the use of physical force, in a democracy, may also be justified by the rights of (at least some of) the very people upon whom force (...) is applied. Focusing on the nature of civil disobedience as a ‘form of address’, I argue: (1) using physical force to address others in the democratic arena does not entail infringing upon their status as autonomous agents; (2) using physical force to address others in the democratic arena may contribute to the fulfilment of a positive duty to promote the autonomy of (at least some of) those very people upon whom force is applied. This is not a defence of paternalism: I claim that using force against others, in the democratic arena, may be constitutive of a behaviour that treats others with the respect due to their status as autonomous agents.

Jason Brennan has argued that democracy is intrinsically unjust, for it grants voting power to politically incompetent individuals, thus exposing people to an undue risk of harm. He claims democracy should be replaced by epistocracy, i.e., the rule of the knowers. In this paper, I show that his argument fails. First, Brennan mistakes voters’ competence for voters’ trustworthiness. Second, despite Brennan's claim to the contrary, an epistocracy may not reduce people’s exposure to an undue risk of harm. Third, Brennan overlooks (...) the fact that citizens are not equally affected by ‘bad voting.’ Fourth, far from being a defence of libertarian ideals, Brennan's argument supports paternalism.

Three of the most recent developments of the “theological turn” in French phenomenology deal explicitly with the question of the form of phenomena. Dealing with the works of Emmanuel Gabellieri, Emmanuel Falque and Jean-Luc Marion, this essay engages into a dialogue with and through French phenomenologists while discussing their philosophical stances – while also incorporating some ideas from authors of the Italian tradition (Sofia Vanni Rovighi, Virgilio Melchiorre and Enzo Melandri). The first part discusses the question of “barriers” and “limits” (...) of phenomenology, followed by a closer examination of how this change in the conception of phenomena (“phenomenomorphosis”) is enacted by the three authors. Considering how the three of them exhibit the signs of what Gabellieri calls a “Christological turn,” the final part before the conclusions addresses the theoretical problem of a theological legitimation of phenomenology.

Many believe that a citizen who engages in civil disobedience is not exempt from the sanctions that apply to standard law-breaking conduct. Since he is responsible for a deliberate breach of the law, he is also liable to punishment. Focusing on a conception of responsibility as answerability, I argue that a civil disobedient is responsible (i.e. answerable) to his fellows for the charges of wrongdoing, yet he is not liable to punishment merely for breaching the law. To support this claim, (...) I defend an account of political obligation framed in terms of respect for (rather than mere obedience to) the law, and argue that the mere illegality of civil disobedience does not suffice to establish wrongdoing. I then discuss and reject three objections to my argument. (shrink)

The fair-play theory of punishment claims that the state is justified in imposing additional burdens on law-breakers, to remove the unfair advantage the latter have enjoyed by disobeying the law. From this perspective, punishment reestablishes a fair distribution of benefits and burdens among all citizens. In this paper, I object to this view by focusing on the case of civil disobedience. I argue that the mere illegality of this conduct is insufficient to establish the agent’s unfair advantage over his lawabiding (...) fellows, hence the imposition of additional burdens upon him through legal punishment. I articulate a broader account of citizens’ fair-play duties, able to capture disobedience as well as obedience to the law. While claiming that some law-breakers may not be treated as free-riders, I also gesture at the fact that some law-obeying citizens may not be ‘playing fair’: in some cases, a failure to engage in civil disobedience represents a failure to do one’s own part within the cooperative scheme of society.

As is well known, any preorder R on a set U induces an Alexandrov topology on U. In some interesting cases related to data mining an Alexandrov topology can be transformed into different types of logico-algebraic models. In some cases, (pre)topological operators provided by Pointless Topology may define a topological space on U even if R is not a preorder. If this is the case, then we call R a crypto-preorder. The paper studies the conditions under which a relation R (...) is a crypto-preorder and how to transform a crypto-preorder into a proper preorder. (shrink)

What is the difference between civil and uncivil disobedience? How can illegal protest be compatible with a democratic regime based on the rule of law? Is Edward Snowden a civil disobedient? This book follows the philosophical debate around these and other issues, showing how the notion of civil disobedience has evolved from a form of passive resistance against injustice, to an active way to engage with the political life of the community. The author presents the major contributions in political and (...) legal philosophy, ranging from John Rawls' seminal account in 1971, to the recent views advanced by Kimberley Brownlee, David Lefkowitz and William Smith. In the last chapter, the author proposes a novel account of civil disobedience, able to meet some of the unresolved challenges. The author argues that, to make sense of civil disobedience, we should expand our conception of political obligation, so to include acts that, despite being illegal, may reveal the agent's civility.

Central topics pertaining to the current debate in the philosophy of action concern the distinction between practical and theoretical reasoning, and the nature of a conclusion in a process of reasoning. In this debate the reference to the Aristotelian reflection is recurrent. In four passages from his works, that is MA. 7, 701a7-b1, EN. H 5, 1147a24-31, EE. B 11, 1227b23-33 and EN. Г 5, 1112bl1-24, Aristotle explores some important aspects of practical reasoning making a parallel with the logical structures (...) of theoretical reasoning. In particular he finds specific analogies between practical and theoretical syllogism, practical and theoretical necessity, deliberation and analysis, action and demonstration. In spite of its specifications, the activity of reason shows its unity. Aristotle considers and deepens the constitutive ingredients of theoretical reasoning in the contest of practical philosophy. The comparison between practical and theoretical reasoning has consequently an expositive purpose, because it supports Aristotle's treatment of action theory. (shrink)

This paper considers the boundaries of "civility" in civil disobedience, by focusing on an extreme form of protest, namely, bossnapping. The latter involves workers 'kidnapping' their bosses, in order to force them to listen to their grievances. I argue that, notwithstanding its use of force, bossnapping may, under some circumstances, fulfil the requirements of a "civil" act of disobedience.

El autor plantea que el Estado ha ingresado en una creciente crisis y la sospecha sobre su real “utilidad” para la sociedad, y vincula a este tema el surgimiento de la cuestión del espacio público. Sostiene que un cambio radical se produce a partir de la nueva percepción del territorio, cuando ya no parece posible que el Estado, y por lo tanto el espacio público, pueda ser pensado exclusivamente en términos nacionales. Discute luego la relación espacio público-vida privada, y los (...) nuevos modos de hacer política en este nuevo espacio público. Afirma finalmente que la construcción de un bien común puede ser pensado y diseñado colectivamente. (shrink)

The complexity and mysteriousness of mental processes during sleep rule out thinking only in term of generators. How could we know exactly what mental sleep experience (MSE) is produced and when? To refer to REM versus NREM as separate time windows for MSE seems insufficient. We propose that in each cycle NREM and REM interact to allow mentation to reach a certain degree of complexity and consolidation in memory. Each successive cycle within a sleep episode should contribute to these processes (...) with a different weight according to the time of night and distance from sleep onset. This view would avoid assuming too great a separation between REM and NREM functions and attributing psychological functions only to a single state. [Nielsen]. (shrink)

This paper explores Aristotle's remarks in Posterior Analytics on certain special disciplines that are subordinate to pure mathematical sciences. Optics, harmonics and mechanics prove their own contents by means of premises belonging to arithmetic or geometry. Even though subaltern sciences are exceptions to the prohibition on kind crossing, the premises to their demonstrations are legitimately appropriate to the relative conclusions. In order to delineate the demonstrative structure of subordinate sciences, Aristotle introduces the distinction between knowledge of a fact and knowledge (...) of the reason for it. In his view, these two different levels of knowledge, characterizing respectively empirical and theoretical approaches, are closely related. Nautical astronomy, for instance, deals with the observation and recording of the astral motions, which are made intelligible by mathematical astronomy. The Aristotelian ideal of an explanatory connection between appearances and mathematical principles seems to be the main aspect in the treatment of subordinate sciences in Posterior Analytics.

Edgar Morin writes that 'rethinking thinking' is what is urgently needed today. Indeed, it is possible to recognize a convergence in the understanding and practice of an integral and open ontology express and promote the living mystery of Being in its multicolored self-expression. This fact calls for a rereading of the tradition of thought, which has matured through history leading to this point. In this perspective, the most significant fruit was produced by the inventio of the ontologically regulating concept of (...) God-Trinity as the interpretive key for the coming in human flesh of the Word/Son Who is God Himself. However, the concept of Trinity failed to completely generate that locus of experience and that relational and communitarian practice of thought corresponding to the Reality it had received and conceived. Our working hypothesis is that philosophy and theology can find the place again for a rebirth and reconfiguration of ontology in the guiding thought of the Trinity, taken up in its original irradiating meaning with the focus on the Christ's cross/resurrection and examined in the still unfathomed promise it contains.

Alzheimer's disease remains the most common form of dementia. Dementia symptoms vary depending on individual personality, life experience, and social and cultural influences. As dementia progresses, involvement of multi-disciplinary health care professionals is needed to manage the disease. Alzheimer research is progressing rapidly. While 5% of all Alzheimer's disease may be genetically determined, the majority is not. Susceptibility genes can reveal the risk of contracting Alzheimer's disease. Early life risk factors such as education, nutrition, and vascular disease may increase the (...) likelihood of dementia in later life. In the United States, two acetylcholinesterase inhibitors have been approved as cognitive enhancers. Possible prevention and symptomatic treatment interventions have focused on estrogen replacement therapy, antioxidants, and anti-inflammatory medications. Research advances have improved the clinical management of dementia. Ethical implications to the patient, family, and society are multiple and remain challenging. (shrink)

In the histories of science, technology and aviation Christiaan Huygens has been unjustly neglected. Documents in the corpus of his works show a life-long interest in the problem of human flight together with some considerable anticipations of, and contributions to, its solution. He was among the first, if not the first, in perceiving the potential of the heavier-than-air approach. He clearly recognized the need for a powerful, mechanical motive source. He stated the first laws of aerodynamics and conceived the modern (...) propeller for propulsion. He was the first to conceive of the aeroplane. His approach to the problem of flying was both global and scientific. (shrink)
