The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more fact-oriented (...) and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

Ontological pluralism is the view that there are different ways to exist. It is a position with deep roots in the history of philosophy, and in which there has been a recent resurgence of interest. In contemporary presentations, it is stated in terms of fundamental languages: as the view that such languages contain more than one quantifier. For example, one ranging over abstract objects, and another over concrete ones. A natural worry, however, is that the languages proposed by the pluralist (...) are mere notational variants of those proposed by the monist, in which case the debate between the two positions would not seem to be substantive. Jason Turner has given an ingenious response to this worry, in terms of a principle that he calls ‘logical realism’. This paper offers a counter-response on behalf of the ‘notationalist’. I argue that, properly applied, the principle of logical realism is no threat to the claim that the languages in question are notational variants. Indeed, there seems to be every reason to think that they are. (shrink)

Giordano Bruno's copy of Camoeracensis Acrotismus from Prague.

C'è un particolare che può apparire secondario, ma che assume un'importanza fondamentale per la ricostruzione della vicenda personale di Giordano Bruno. Si tratta dell'abito monacale.

Il testo analizza le principali proposte interpretative dedicate alla filosofia di Giordano Bruno da parte di alcuni storiografi del '900, per proporre una propria visione dell'autore nolano.

La Cappella Carafa di Santa Severina, nella chiesa di San Domenico Maggiore a Napoli, era uno dei luoghi preferiti della giovinezza di Giordano Bruno. La sua struttura, che ricorda il teatro di Giulio Camillo, e la presenza di trenta simboli astrologici scolpiti sugli archi, la rendono la “stanza della memoria” ideale per l’applicazione dell’innovativa arte della memoria sviluppata dal filosofo Nolano. -/- The ‘memory place’ of Giordano Bruno.

A pesar de que Bruno Latour es considerado iniciador de un área académica denominada estudios de la ciencia, no se ha destacado lo suficiente que sus textos constituyen fundamentalmente una teoría metafísica cuya tesis central –mantenida a lo largo de la mayor parte de su obra- es que no hay una diferencia real entre “palabra y mundo”, entre un enunciado que se refiere a un hecho y ese mismo hecho, sino una serie de relaciones o “redes” (que denomina “fluido”, (...) “la masa de las transformaciones” o “referencia circulante”) donde ocurren estabilizaciones transitorias. En tanto niega que entidades y estados de cosas efectivos existan independientemente, ya no de que una conciencia piense en ellos, sino de las afirmaciones que hay en la cultura sobre su existencia, este enfoque es una variante, de carácter semántico y social, de lo que la filosofía moderna denominó idealismo metafísico. Pero tanto el problema metafísico de la existencia como el de la existencia independientemente de algo se enfrentan con la dificultad semántica de que ningún argumento descriptivo puede dejar de aludir a sus referentes, por lo que ninguno puede probar que exista algo independientemente del lenguaje, sino sólo suponerlo al adoptar una ontología.

Quando la biblioteca diventa un confessionale.

L’articolo si propone di chiarire uno dei punti oscuri della biografia di Giordano Bruno. Nel 1571 il Capitolo generale dei Domenicani di Roma lo assegnò come studente formale allo Studio di Andria. Secondo i suoi più importanti biografi, il Nolano non ci sarebbe mai andato. Attraverso l’accurata analisi dei documenti relativi al corso di studi, e il riscontro delle citazioni contenute in alcune opere, l’ipotesi che Bruno abbia soggiornato ad Andria per circa un anno appare, invece, estremamente probabile.

In 1571 the General Chapter of the Dominicans in Rome assigned him, as a formal student, to the Study of Andria. According to his most important biographers, the Nolan never went there. However, through the careful analysis of the documents relating to his course of studies, and the comparison of the quotations contained in some of his works, the hypothesis that Bruno stayed in Andria for about a year appears extremely probable.

Regarding the influence of Francois Rabelais on the Giordano Bruno’s works, up to now the criticism have only taken into consideration the lexical and thematic analogies. This article individualizes, in a passage of the "Oratio Valedictoria", a literal quotation from the Gargantua et Pantagruel , showing that Rabelais was adirect source of inspiration for Bruno. The protagonist of the passage is the pythagorean Apollonius of Tyana, a character well known from the Nolan, who mentioned him in many occasions. (...)

Besides, heembodies the model of the "natural magician" in which the philosopher repeatedly identified himself, both inhis works and life. (shrink)

Latour does not seek any “hidden” reasons behind actions; there is not a dictionary or encyclopedia explaining the sources of the behaviors of the actors. No meta-language is in question. The analyst cannot address any invisible agency. If an agency is invisible, then it has no effect, therefore it is not an agency. If an analyst says: “No one mentions it. For Latour, agency is not limited to human beings, but objects should also be counted as agents which is one (...) of the most attractive aspect of actor-network theory. (shrink)

IL MOSTRO E L'EROE. Quando Pomponio Algieri da Nola, all’età di soli 24 anni, viene bruciato vivo a Roma in piazza Navona, Giordano Bruno di anni ne ha appena otto. Oltre che per la giovane età del condannato, l’esecuzione è insolita anche per il luogo e il metodo scelto dall’Inquisizione: anziché le solite fascine, per alimentare il fuoco viene approntato un pentolone di pece, olio e trementina, nel quale viene immersa la povera vittima.

Il rogo di Giordano Bruno e la sua inquieta filosofia continuano a far pensare; dal 1586 al 1590 il Nolano trascorse in Germania uno dei pochi periodi di serenità della sua esistenza tormentata ed errabonda: l'Oratio Valedictoria e l'Oratio Consolatoria, composte in quegli anni per esternare la sua riconoscenza nei confronti di chi lo aveva accolto con rispetto e magnanimità, sciolgono un vero e proprio inno a quegli ideali per la cui difesa l'ex domenicano lottò incessantemente, fino all'estrema conseguenza (...) del rogo di Campo de' fiori, il 17 febbraio 1600. Amore per la sapienza, tolleranza e libertà di pensiero, al di là di ogni divisione politica o religiosa, vengono qui affermati come criteri di distinzione tra ingegno e bestialità umana. (shrink)

I argue against the interpretation of propositions as intentions and proof-objects as fulfillments proposed by Heyting and defended by Tieszen and van Atten. The idea is already a frequent target of criticisms regarding the incompatibility of Brouwer’s and Husserl’s positions, mainly by Rosado Haddock and Hill. I raise a stronger objection in this paper. My claim is that even if we grant that the incompatibility can be properly dealt with, as van Atten believes it can, two fundamental issues indicate that (...) the interpretation is unsustainable regardless: (1) it is hard to determine, without appealing to propositional intentions on pain of circularity, what intention a proof-object should be understood as a fulfillment of; (2) due to a difficult fulfillment dilemma, it is unclear, at best, what the object of an intention corresponding to a proposition is.

Abstract: The standard picture of rationality requires that the agent acts so as to realize her most preferred alternative in the light of her own desires and beliefs. However, there are circumstances where such an agent can predict that she will act against her preferences. The story of Ulysses and the Sirens is the paradigmatic example of such cases. In those circumstances the orthodoxy requires the agent to be ‘sophisticated’. That is to say, she should take into account her expected (...) future choices and prevent her future self to act in certain ways. She should ‘bind’ herself to a certain course of action. This is a form of causal commitment. It is generally recognized that this form of self-commitment is the only one that is available to a rational agent. Rational commitment, where the agent gives herself a reason to act in a certain way rather than making herself act in that way, is considered not feasible. In this paper, I question this verdict. I sketch the broad outlines of a model of rational commitment, which takes as its starting point Michael Bratman’s ‘planning theory’ of intention. There are two important objections against this theory (one by John Broome and one by the Dutch philosopher Govert den Hartogh.) Both criticisms claim that such a theory is a form of ‘bootstrapping’ reasons for action into existence. In the remainder of the paper, I will defend the theory against these objections. This way, I hope to establish that defending the feasibility of rational commitment is not an obvious mistake. (shrink)

The mystery of the images and an unknown book.

The philosopher and his passion for the “gentle sex”.

Un mistero svelato,fra magia,alchimia e filosofia.

Fichte assigns ‘intellectual intuition’ a new meaning after Kant. But in 1799, his doctrine of intellectual intuition is publicly deemed indefensible by Kant and nihilistic by Jacobi. I propose to defend Fichte’s doctrine against these charges, leaving aside whether it captures what he calls the ‘spirit’ of transcendental idealism. I do so by articulating three problems that motivate Fichte’s redirection of intellectual intuition from being to acting: (1) the regress problem, which states that reflecting on empirical facts of consciousness leads (...) only to further facts and so cannot yield a first principle; (2) the rhapsody problem, which states that the categories form a haphazard set and so lack necessity unless they derive from a first principle; and (3) the nihilism problem, which states that a first principle cannot lie outside our cognition of it, lest it be the cause of our cognition and, being first, the cause of all our actions, reducing us to machines. Crucially, Fichte’s three motivating problems are in fact aspects of a single problem. Leaving any aspect unsolved spoils putative solutions to the other two. Consequently, Fichte requires a single unified solution to all three, which his doctrine of intellectual intuition provides. (shrink)

A mistery unveiled, among magic, alchemy and philosophy.

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)

Are there different sizes of infinity? That is, are there infinite sets of different sizes? This is one of the most natural questions that one can ask about the infinite. But it is of course generally taken to be settled by mathematical results, such as Cantor’s theorem, to the effect that there are infinite sets without bijections between them. These results settle the question, given an almost universally accepted principle relating size to the existence of functions. The principle is: for (...) any sets A and B, if A is the same size as B, then there is a bijection from A to B. The aim of the paper, however, is to argue that this question is in fact wide open: to argue that we are not in a position to know the answer, because we are not in one to know the principle. The aim, that is, is to argue that for all we know there is only one size of infinity. (shrink)

In a series of papers Ladyman and Presnell raise an interesting challenge of providing a pre-mathematical justification for homotopy type theory.

Metaphysically possible worlds have many uses. Epistemically possible worlds promise to be similarly useful, especially in connection with propositions and propositional attitudes. However, I argue that there is a serious threat to the natural accounts of epistemically possible worlds, from a version of Russell’s paradox. I contrast this threat with David Kaplan’s problem for metaphysical possible world semantics: Kaplan’s problem can be straightforwardly rebutted, the problems I raise cannot. I argue that although there may be coherent accounts of epistemically possible (...) worlds with fruitful applications, any such an account must fundamentally compromise the basic idea behind epistemic possibility.

Dall'autore del più visitato sito web dedicato a Giordano Bruno, un volume in chiusura dell'anno bruniano, edito da Marotta & Cafiero: WWW.Giordano Bruno di Guido del Giudice è un assai originale pubblicazione che trova nella passione filosofica di chi lo ha scritto la sua più profonda motivazione.

Esta edição contém a única transcrição estudantil sobrevivente das Lições de Metafísica de Kant da década de 1770. A Lição foi ministrada o mais tardar no inverno de 1779/80 e, portanto, antes mesmo da publicação da Crítica da Razão Pura (1781). Um exceção é, contudo, a parte sobre a ontologia que seguramente se remonta a uma Lição que Kant ministrou depois de 1781. Estas transcrições de Lições são de valor inestimável para a história do desenvolvimento da filosofia de Kant e, (...) em especial, para a gênese de sua Crítica da Razão Pura . Elas representam também um complemento importante para suas outras Lições, como por exemplo, as de antropologia, nas quais Kant também se ocupou com as questões da psicologia empírica e racional. É interessante observar que Kant se serve de métodos distintos, nas Lições de Antropologia e de Metafísica, para demonstrar a substancialidade e a imortalidade da alma. Embora Kant ainda leve a doutrina da alma da psicologia racional muito a sério na Metafísica-Pölitz, ele rejeitará de fato suas pretensões de conhecimento pouco tempo depois na Crítica na seção sobre os paralogismos da doutrina pura da alma. Aquele que deseja se aprofundar na filosofia de Kant e conhecer seu contexto histórico-filosófico não pode deixar de ler as Lições de Metafísica-Pölitz. Heiner F.

The purpose of this article is to present the influence of Plotinus' thought on the political philosophy of the Roman Emperor Julian, between the years 361 to 363. The methodology consists of selecting excerpts from the works of Juliano Misopogon and Cartas y Fragmentos that may indicate the influence of the ideas of Plotinus' Ennead in the speech given by the Emperor to legitimize his political power. Juliano argues that the laws of the empire were created by the gods for (...) the organization of human life, so that obedience to the gods necessarily requires an obedience to those laws. According to Juliano, knowledge or episteme about the laws of empire is conditioned to the escape from sensible reality in the name of spiritual reality, in which the wise ruler also needs to transcend the body to know and obey divine laws. Thus, after analyzing Juliano's arguments, we seek to reflect on the viability of the political system adopted by him, especially if the reception of his ideas by rulers from the 20th century onwards is considered.

A filosofia do direito internacional de Hegel tem recebido certa atenção nos últimos anos. As pesquisas mais recentes têm buscado apresentar uma visão diferente daquela, apresentada no século XIX e primeira metade do século XX, que retratava Hegel como um entusiasta do estado de guerra.

Meu objetivo nesse artigo é, primeiramente, apresentar os aspectos (...) gerais da filosofia do direito internacional de Hegel, enfatizando seu diálogo com Kant. Tento mostrar como Hegel está, em sua discussão, em referência a importantes aspectos do texto kantiano sobre a paz perpétua. Em segunda instância, partindo desse diálogo, argumento que, embora Hegel seja certamente muito mais um crítico do projeto kantiano do que um simpatizante, as implicações últimas de seu pensamento mostram-se, em alguma medida, alinhadas com as da filosofia de Kant.

This paper argues that we should solve paradoxes for propositions (such as the Russell–Myhill paradox) in essentially the same way that we solve Russellian paradoxes for sets. That is, the standard, iterative approach to sets is extended to include properties, and then the resulting hierarchy of sets and properties is used to construct propositions. Propositions on this account are structured in the sense of mirroring the sentences that express them, and they would seem to serve the needs of philosophers of (...) language and metaphysicians who rely on such propositions. The resulting account has limitations, comparable to those faced by the iterative approach to sets, but it is argued to be in important ways preferable to others that have been proposed. (shrink)

A necessarily true sentence is 'brute' if it does not rigidly refer to anything and if it cannot be reduced to a logical truth. The question of whether there are brute necessities is an extremely natural one. Cian Dorr has recently argued for far-reaching metaphysical claims on the basis of the principle that there are no brute necessities: he initially argued that there are no non-symmetric relations, and later that there are no abstract objects at all. I argue that there (...) are nominalistically acceptable brute necessities, and that Dorr's arguments thus fail. My argument is an application of Gödel's first incompleteness theorem. (shrink)

The extent of the originality and relevance of Kant's ethics is undeniable. But it is not so evident the fact that the Kant's moral philosophy as a whole was not suddenly built, but it was dependent on a profound debate with the philosophical tradition, especially with the German scholastic tradition, a debate which led to the assimilation or appropriation of several of its aspects. With special regard to the history of the development of the categorical imperative, it is not possible (...) to be indifferent to the influence of the practical philosophy of the Enlightenment German philosopher and theologian, Christian August Crusius. The aim of this article is thus to try to identify, taking into account the distinction of praxis in problematic and moral and the contrast between prudence and morality, some points of intersection between the moral philosophy of Crusius and Kant in its origin.

This article offers a libertarian re-examination of Brazilian political history focusing mainly on the first few decades of the 19th century. The article finds two main tendencies lurking behind the various political parties and labels of the time: one, associated mainly with the Conservative Party, leaned dangerously away from the individual liberties advocated by classical liberalism and instead more toward authoritarian forms of government. The other, associated mainly with the Liberal Party, was more libertarian in nature. This article also concludes (...) that other examinations of these budding political parties fall short by overlooking a potentially authoritarian state underlying the Conservative project that dominated politics in Brazil at the time.

Il existe de nombreuses sources d’exigences. Certaines exigences sont normatives dans la mesure où elles impliquent des affirmations concernant ce que nous avons raison de croire, faire, désirer, etc. À ce titre, les exigences morales sont parmi les meilleures candidates. Si la morale exige que l’on tienne notre promesse, il semble que nous avons une raison de la tenir. Cependant, ce ne sont pas toutes les exigences qui sont normatives en ce sens. Le catholicisme exige que l’on assiste à la (...) messe chaque dimanche. Il ne s’ensuit pas pour autant que nous avons une raison d’y assister. Pourquoi cela? Pourquoi certaines exigences sont normatives en ce sens, mais pas d’autres?

Sono ormai parecchi anni, credo una decina, che Guido del Giudice ha intrapreso l’opera di raccontarci e definirci meglio l’opera di Giordano Bruno.

On the classical understanding, an agent is fully excused for an action if and only if performing this action was a case of faultless wrongdoing. A major motivation for this view is the apparent existence of paradigmatic types of excusing considerations, affecting fault but not wrongness. I show that three such considerations, ignorance, duress and compulsion, can be shown to have direct bearing on the permissibility of actions. The appeal to distinctly identifiable excusing considerations thus does not stand up to (...) closer scrutiny, undermining the classical view and giving us reason to seek alternative ways of drawing the justification/excuse distinction.

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a process (...) of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’.

Kripke [1975] gives a formal theory of truth based on Kleene's strong evaluation scheme. It is probably the most important and influential that has yet been given—at least since Tarski. However, it has been argued that this theory has a problem with generalized quantifiers such as All—that is, All ϕs are ψ—or Most. Specifically, it has been argued that such quantifiers preclude the existence of just the sort of language that Kripke aims to deliver—one that contains its own truth predicate. (...) In this paper I solve the problem by showing how Kleene's strong scheme, and Kripke's theory based on it, can in a natural way be extended to accommodate the full range of generalized quantifiers.

Fichte argues that the conclusion of Kant’s transcendental deduction of the categories is correct yet lacks a crucial premise, given Kant’s admission that the metaphysical deduction locates an arbitrary origin for the categories. Fichte provides the missing premise by employing a new method: a genetic deduction of the categories from a first principle. Since Fichte claims to articulate the same view as Kant in a different, it is crucial to grasp genetic deduction in relation to the sorts of deduction that (...) Kant offers. I propose to interpret genetic deduction as the simultaneous fulfillment of two tasks: answering the question quid facti by deriving the categories from the I and answering the question quid juris by establishing our entitlement to the categories as conditions of experience. While the second task represents Fichte’s agreement with Kant’s transcendental deduction, the first reflects his correction of Kant’s metaphysical deduction. (shrink)

É possível constatar, mesmo em uma leitura superficial, que Kant tem o propósito de empreender em seu opúsculo de 1795, À Paz Perpétua, uma defesa dos princípios normativos do direito em todas as esferas da vida pública. Isso se evidencia na tentativa de desenvolver uma teoria da paz erigida sobre uma teoria tríplice do direito público, dividida nos âmbitos do direito estatal, das gentes e cosmopolita. Mas, se a questão é, por um lado, adequar os princípios puros da doutrina do (...) direito à teoria da paz, por outro, o problema com o qual Kant tem de lidar é essencialmente histórico. Não se trata apenas de justificar, em um contexto abrangente, a normatividade dos princípios do direito, mas também de demonstrar a sua aplicabilidade. Por conseguinte, em seu empreendimento, Kant encontra-se diante do desafio de demonstrar a inconsistência da “expressão corrente”, com a qual teve que lidar antes, que diz que “isto pode ser correto na teoria, mas nada vale na prática”. Tal preocupação pode ser observada direta e indiretamente, em várias passagens, no decorrer do texto, explicitando-se ,sobretudo, na discussão apresentada no Suplemento Primeiro no qual a questão suscitada pelo problema da teoria e prática, acerca das condições de possibilidade de realização do ideal da paz, é discutida no contexto de sua filosofia da história e também no Apêndice I, no qual, através de uma reflexão sobre o consenso entre moral e política, o que se põe em questão é a possibilidade da concordância entre teoria e prática no contexto da filosofia e da prática política. Ocupar-me-ei nesse texto apenas em tratar da questão sob esse segundo aspecto, tentando destacar que a estratégia kantiana para superar o problema da teoria e prática, no âmbito da filosofia política, depende do desenvolvimento de uma “renovada” doutrina da prudência. Como observa Castillo1, “[p]ara provar que a teoria jurídica da paz se aplica na teoria e na prática ao mesmo tempo”, Kant “deve fazer um exame crítico do conceito de prudência do Estado”2 . Esta análise deve nos permitir concluir, em primeiro lugar, que, bem diferente da visão antes difundida de que a filosofia política de Kant é expressão de um moralismo “que é certamente sincero, mas basicamente ingênuo”3, o objetivo de Kant, na verdade, nunca foi o de se afastar da realidade concreta da política em nome de um ideal abstrato de virtude política. Sua preocupação foi, em vez disso, a de ajustar os co. (shrink)

This article argues that using Joseph Raz’s service conception of authority to reject philosophical anarchism can be affected by political anarchism. Whereas philosophical anarchism only denies the authority of the state, political anarchism claims that anarchism is a better alternative to the state. Raz’s theory holds that an institution has authority if it enables people to better conform with reason. I argue that there are cases where anarchism is an existing alternative to the state and better fulfils this condition. Consequently, (...) in these cases, anarchist groups and societies and not the state have legitimate authority. When anarchism is not an existing alternative to the state, the state will, under Raz’s theory, have some legitimate authority, but that authority will be limited because anarchism remains a better possible alternative to the state. To support the political anarchist claim I discuss the anarchist collectives during the Spanish civil war, which I argue are an example of anarchism as an existing alternative to the state that better fulfils Raz’s service conception and also provide suggestive evidence that anarchism is in general a better possible alternative. I also discuss the relationship between political anarchism and authority and I argue that despite some tension they are not irreconcilable. I conclude that the interesting anarchist challenge for political theorists is political not philosophical. (shrink)

This article focuses on the use of one verse from the Biblical Songs of Songs in central passages of Giordano Bruno's first published book on the art of memory. De umbris idearum [On the Shadows of Ideas] not solely aims at improving mnemonic capacities, it also envisages the preconditions and limits of cognition in Bruno's new inifitist cosmology. Taking relevant scholarly literature on the topic as a point of departure, this contribution presents De umbris in the context of (...) Bruno's philosophy in general; it focuses on Bruno's evocation of Origen's commentary on that passage in the Song of Songs. The article analyzes in detail the reasons for Bruno's subversion of the traditional exegetic tradition that was massively influenced by Origen's spiritualized reading of the Song of Songs. Bruno's misappropriation of the Origen's commentary turns out to be a mise en abyme, a mannerist strategy of representation. It not only reflects the very method that underlies Bruno's art of memory, but is also to be understood as a conscious subversion of exegetic traditions in general. (shrink)
