The use of “levels of abstraction” in philosophical analysis (levelism) has recently come under attack. In this paper, I argue that a refined version of epistemological levelism should be retained as a fundamental method, called the method of levels of abstraction. After a brief introduction, in section “Some Definitions and Preliminary Examples” the nature and applicability of the epistemological method of levels of abstraction is clarified. In section “A Classic Application of the Method ofion”, the philosophical fruitfulness of the new method is shown by using Kant’s classic discussion of the “antinomies of pure reason” as an example. In section “The Philosophy of the Method of Abstraction”, the method is further specified and supported by distinguishing it from three other forms of “levelism”: (i) levels of organisation; (ii) levels of explanation and (iii) conceptual schemes. In that context, the problems of relativism and antirealism are also briefly addressed. The conclusion discusses some of the work that lies ahead, two potential limitations of the method and some results that have already been obtained by applying the method to some long-standing philosophical problems

One of the open problems in the philosophy of information is whether there is an information logic (IL), different from epistemic (EL) and doxastic logic (DL), which formalises the relation “a is informed that p” (Iap) satisfactorily. In this paper, the problem is solved by arguing that the axiom schemata of the normal modal logic (NML) KTB (also known as B or Br or Brouwer’s system) are well suited to formalise the relation of “being informed”. After having shown that IL can be constructed as an informational reading of KTB, four consequences of a KTB-based IL are explored: information overload; the veridicality thesis (Iap → p); the relation between IL and EL; and the Kp → Bp principle or entailment property, according to which knowledge implies belief. Although these issues are discussed later in the article, they are the motivations behind the development of IL.

In this article, I outline a logic of design of a system as a specific kind of conceptual logic of the design of the model of a system, that is, the blueprint that provides information about the system to be created. In section two, I introduce the method of levels of abstraction as a modelling tool borrowed from computer science. In section three, I use this method to clarify two main conceptual logics of information inherited from modernity: Kant’s transcendental logic of conditions of possibility of a system, and Hegel’s dialectical logic of conditions of in/stability of a system. Both conceptual logics of information analyse structural properties of given systems. Strictly speaking, neither is a conceptual logic of information about the conditions of feasibility of a system, that is, neither is a logic of information as a logic of design. So, in section four, I outline this third conceptual logic of information and then interpret the conceptual logic of design as a logic of requirements, by introducing the relation of “sufficientisation”. In the conclusion, I argue that the logic of requirements is exactly what we need in order to make sense of, and buttress, a constructionist approach to knowledge.

Quand on se penche sur l’héritage philosophique de Turing, deux risques se posent. Le premier, c’est de le réduire à son test célèbre (Turing 1950). Ce qui a toutefois le mérite de la clarté. N’importe qui peut reconnaître la contribution en question et la situer dans le débat important sur la philosophie de l’intelligence artificielle. Le second risque est de le diluer dans un récit universel, faisant des idées deTuring les graines de tout ce que nous faisons et savons aujourd’hui. Ceci a l’avantage de reconnaître la grandeur de ce génie. Cependant, dans un cas comme dans l’autre, nous allons probablement moins identifier les contributions conceptuelles deTuring qui nous ont aidés à forger un discours philosophique contemporain et qui méritent d’être approfondies et développées. Pour éviter ces deux risques, je me concentrerai dans les pages suivantes sur trois leçons philosophiques spécifiques, qui me semblent particulièrement significatives pour l’émergence de la philosophie de l’information et ses développements. Je ne propose pas ici une analyse philologique ni savante,mais un exercice minimaliste, herméneutique. Façon de faire écho àla démarche deTuring et de rendre hommage àson génie extraordinaire :ses interprètes n’ont pas fini de tirer parti de son héritage intellectuel. Je souhaite qu’un jourTuring devienne aussi important que Frege dans notre canon philosophique.

Information has always been at the core of conflicts. When Napoleon planned to invade Italy, he duly upgraded the first telegraph network in the world, the French “semaphore”. He famously remarked that “an army marches on its stomach,” but he also knew that the same army acted on information. As Von Clausewitz once stated “by the word ‘information’ we denote all the knowledge which we have of the enemy and his country; therefore, in fact, the foundation of all our ideas of actions [in war].”I am very grateful to Mariarosaria Taddeo for this citation and for our fruitful collaboration on a 2-year project about the ethics of information warfare, Marie Curie Fellowship Grant, FP7-PEOPLE-2009-IEF see now . This is why the radar, the computer, the satellite, the GPS system, and the Internet were initially developed as military technologies, while unmanned vehicles are becoming a reality thanks to DARPA. The difference between then and now is that information warfare ..

In this paper, I present an informational approach to the nature of personal identity. In “Plato and the problem of the chariot”, I use Plato’s famous metaphor of the chariot to introduce a specific problem regarding the nature of the self as an informational multiagent system: what keeps the self together as a whole and coherent unity? In “Egology and its two branches” and “Egology as synchronic individualisation”, I outline two branches of the theory of the self: one concerning the individualisation of the self as an entity, the other concerning the identification of such entity. I argue that both presuppose an informational approach, defend the view that the individualisation of the self is logically prior to its identification , and suggest that such individualisation can be provided in informational terms. Hence, in “A reconciling hypothesis: the three membranes model”, I offer an informational individualisation of the self, based on a tripartite model, which can help to solve the problem of the chariot. Once this model of the self is outlined, in “ICTs as technologies of the self” I use it to show how ICTs may be interpreted as technologies of the self. In “The logic of realisation”, I introduce the concept of “realization” (Aristotle’s anagnorisis ) and support the rather Spinozian view according to which, from the perspective of informational structural realism, selves are the final stage in the development of informational structures. The final “Conclusion: from the egology to the ecology of the self” briefly concludes the article with a reference to the purposeful shaping of the self, in a shift from egology to ecology

This paper discusses the influence of Sextus Empiricus' works on Renaissance culture and the recovery of Pyrrhonism during the fifteenth and sixteenth centuries. It investigates what primary and secondary sources were available at the time, and who knew and made use of such sources. The article concludes that the dearth of Pyrrhonic arguments in Renaissance literature was due to the prevailing and incompatible culture of humanism rather than to a lack of interest in Sextus Empiricus’ works during this period.

Information and Communication Technologies have profoundly changed many aspects of life, including the nature of entertainment, work, communication, education, healthcare, industrial production and business, social relations and conflicts. They have had a radical and widespread impact on our moral lives and hence on contemporary ethical debates. The Cambridge Handbook of Information and Computer Ethics, first published in 2010, provides an ambitious and authoritative introduction to the field, with discussions of a range of topics including privacy, ownership, freedom of speech, responsibility, technological determinism, the digital divide, cyber warfare, and online pornography. It offers an accessible and thoughtful survey of the transformations brought about by ICTs and their implications for the future of human life and society, for the evaluation of behaviour, and for the evolution of moral values and rights. It will be a valuable book for all who are interested in the ethical aspects of the information society in which we live.

The anti-counterfeiting trade agreement was originally meant to harmonise and enforce intellectual property rights provisions in existing trade agreements within a wider group of countries. This was commendable in itself, so ACTA’s failure was all the more disappointing. In this article, I wish to contribute to the post-ACTA debate by proposing a specific analysis of the ethical reasons why ACTA failed, and what we can learn from them. I argue that five kinds of objections—namely, secret negotiations, lack of consultation, vagueness of formulation, negotiations outside any international body, and the creation of a new governing body outside already existing forums—had only indirect ethical implications. This takes nothing away from their seriousness but it does make them less compelling, because agreements should be evaluated, ethically, for what they are, rather than for the alleged reasons why they are being proposed. I then argue that ACTA would have caused three ethical problems: an excessive and misplaced kind of responsibility, a radical decrease in freedom of expression, and a severe reduction in information privacy. I conclude by indicating three lessons that can help us in shaping a potential ACTA 2.0. First, we should acknowledge the increasingly vital importance of the framework of implicit expectations, attitudes, and practices that can facilitate and promote morally good decisions and actions. ACTA failed to perceive that it would have undermined the very framework that it was supposed to foster, namely one promoting some of the best and most successful aspects of our information society. Second, we should realise that, in advanced information societies, any regulation affecting how people deal with information is now bound to influence the whole ‘onlife’ habitat within which they live. So enforcing IPR becomes an environmental problem. Third, since legal documents, such as ACTA, emerge from within the infosphere that they affect, we should apply to the process itself, which one day may lead to a post-ACTA treaty, the very framework and ethical values that we would like to see promoted by it.

En los últimos años la «Ética de la Información» ha llegado a tener sentidos distintos para los distintos investigadores que trabajan en una amplia variedad de disciplinas. Esta situación es lamentable, ya que ha producido cierta confusión sobre la naturaleza específica y el alcance de la EI. En el presente artículo se defiende una Ética de la Información que sostiene que el comportamiento y el estatus de los objetos informacionales qua objetos informacionales puede tener un significado moral que vaya más allá de la función instrumental que les atribuyen otras perspectivas éticas y que, por lo tanto, mantiene que pueden contribuir a determinar de manera normativa los deberes éticos y los derechos legalmente exigibles

One of the pressing challenges we face today—in a post-Westphalian order and post-Bretton Woods world —is how to design the right kind of MAS that can take full advantage of the socio-economic and political progress made so far, while dealing successfully with the new global challenges that are undermining the best legacy of that very progress. This is the topic of the article. In it, I argue that in order to design the right kind of MAS, we need to design the right kind of norms that constitute them; in order to design the right kind of constitutive norms, we need to identify and adopt the right kind of principles of normative design; toleration is one of those principles; unfortunately, its role as a foundation for the design of norms has been undermined by the “paradox of toleration”; however, the paradox can be solved; so toleration can be re-instated as the right kind of foundational principle for the design of the right kind of norms that can constitute the right kind of MAS that can operate across cultures, societies and states, to help us to tackle the new global challenges facing us

In previous works (Floridi 2018) I introduced the distinction between hard ethics (which may broadly be described as what is morally right and wrong independently of whether something is legal or illegal), and soft or post-compliance ethics (which focuses on what ought to be done over and above existing legislation). This paper analyses the applicability of soft ethics to the General Data Protection Regulation and advances the theory that soft ethics has a dual advantage—as both an opportunity strategy and a risk management solution.

There is a wealth of resources— ideas, insights, discoveries, inventions, traditions, cultures, languages, arts, religions, sciences, narratives, stories, poems, customs and norms, music and songs, games and personal experiences, and advertisements—that we produce, curate, consume, transmit, and inherit as humans. This wealth, which I define as semantic capital, gives meaning to, and makes sense of, our own existence and the world surrounding us. It defines who we are and enables humans to develop an individual and social life. This paper discusses the shift from analog to digital semantic capital, and the extent to which this might affect the semanticisation of our identities, our lives and our realities.

Semantic information is usually supposed to satisfy the veridicality thesis: p qualifies as semantic information only if p is true. However, what it means for semantic information to be true is often left implicit, with correspondentist interpretations representing the most popular, default option. The article develops an alternative approach, namely a correctness theory of truth (CTT) for semantic information. This is meant as a contribution not only to the philosophy of information but also to the philosophical debate on the nature of truth. After the introduction, in Sect. 2, semantic information is shown to be translatable into propositional semantic information (i). In Sect. 3, i is polarised into a query (Q) and a result (R), qualified by a specific context, a level of abstraction and a purpose. This polarization is normalised in Sect. 4, where [Q + R] is transformed into a Boolean question and its relative yes/no answer [Q + A]. This completes the reduction of the truth of i to the correctness of A. In Sects. 5 and 6, it is argued that (1) A is the correct answer to Q if and only if (2) A correctly saturates Q by verifying and validating it (in the computer science’s sense of verification and validation ); that (2) is the case if and only if (3) [Q + A] generates an adequate model (m) of the relevant system (s) identified by Q; that (3) is the case if and only if (4) m is a proxy of s (in the computer science’s sense of proxy ) and (5) proximal access to m commutes with the distal access to s (in the category theory’s sense of commutation ); and that (5) is the case if and only if (6) reading/writing (accessing, in the computer science’s technical sense of the term) m enables one to read/write (access) s. Sect. 7 provides some further clarifications about CTT, in the light of semantic paradoxes. Section 8 draws a general conclusion about the nature of CTT as a theory for systems designers not just systems users. In the course of the article all technical expressions from computer science are explained

The article addresses the problem of how semantic information can be upgraded to knowledge. The introductory section explains the technical terminology and the relevant background. Section 2 argues that, for semantic information to be upgraded to knowledge, it is necessary and sufficient to be embedded in a network of questions and answers that correctly accounts for it. Section 3 shows that an information flow network of type A fulfils such a requirement, by warranting that the erotetic deficit, characterising the target semantic information t by default, is correctly satisfied by the information flow of correct answers provided by an informational source s. Section 4 illustrates some of the major advantages of such a Network Theory of Account (NTA) and clears the ground of a few potential difficulties. Section 5 clarifies why NTA and an informational analysis of knowledge, according to which knowledge is accounted semantic information, is not subject to Gettier-type counterexamples. A concluding section briefly summarises the results obtained

The subject is Sextus Empiricus, one the chief sources of information on ancient philosophy and one of the most influential authors in the history of skepticism. Sextus' works have had an extraordinary influence on western philosophy, and this book provides the first exhaustive and detailed study of their recovery, transmission, and intellectual influence through Late Antiquity, the Middle Ages, and the Renaissance. This study deals with Sextus' biography, as well as the history of the availability and reception of his works. It also contains an extensive bibliographical section, including editions, translations, and commentaries.
