Full textThe objective of this dissertation is first to present the fundamental part of Frege's logicist project - that became known as Frege's theorem - as an independent mathematical result in order to then evaluate its philosophical significance through a discussion of Frege's concept of logic. Besides, there are two appendixes in which a general recursion theorem is proven inside a classical second-order logical system and a neofregean construction of the real numbers from Cauchy sequences is presented
O objetivo desta dissertação e, em primeiro lugar, apresentar o núcleo fundamental do projeto logicista fregeano - o que ficou conhecido pelo nome de teorema de Frege - como um resultado matemático independente para, em seguida, avaliar o seu significado filosófico por meio da discussão acerca do conceito fregeano de logica. Além disso, este trabalho contém dois anexos, nos quais se demonstra um teorema geral de recursão dentro de um sistema clássico de logica de segunda ordem e se apresenta uma construção neofregeana dos números reais por meio de sequências de Cauchy

A filosofia kantiana da matemática é fundamentada sobre uma estrutura epistemológica intuicionista. As categorias do espaço e do tempo constituem as formas da sensibilidade, formas estas manifestadas por meio de uma intuição pura a priori. O presente trabalho busca realizar uma defesa razoável de tal intuição frente aos críticos contemporâneos, os quais propõem um programa logicista desprovido de estrutura epistêmica no que tange ao raciocínio matemático. Tais críticos afirmam que a aritmética não necessita da intuição pura do tempo para que as operações numéricas possam ser realizadas. Buscaremos demonstrar que a lógica quantificacional constitui um expediente meramente formalista que deixa de lado os problemas epistemológicos da cognição matemática e, por esse motivo, pode ambicionar desconsiderar a intuição pura kantiana. Portanto, buscaremos demonstrar que a intuição pura kantiana ainda pode lançar luz sobre a natureza dos cálculos da matemática.
The Kantian philosophy of mathematics is based on an intuitionist epistemological structure. The categories of space and time are the forms of sensibility, these forms manifested through a pure intuition a priori. The present work seeks to make a reasonable defense of such intuition in the face of contemporary critics, who propose a logicist program devoid of epistemic structure regarding mathematical reasoning. Such critics claim that arithmetic does not need the pure intuition of time for numerical operations to be performed. We will try to demonstrate that the quantificational logic constitutes a merely formalistic expedient that leaves aside the epistemological problems of the mathematical cognition and, for this reason, it can ambition to disregard the pure Kantian intuition. Therefore, we shall try to demonstrate that pure Kantian intuition can still shed light on the nature of mathematical calculations.

Full textIn this PhD thesis, I attempt to reevaluate the opposition between analytical and phenomenological philosophy through the study of Husserl’s and Carnap’s systems of constitution. Carnap’s idea of constitution as a “rational” and arbitrary “reconstruction” of the world seems to be radically antithetical to Husserl’s descriptive account of the “self-constitution” of the things themselves. Yet, Carnap’s use of the language of constitution, as well as his attempt to translate it into the language of logistics, lead us to question the links between his own enterprise and Husserl’s transcendental idealist constitution. What I am trying to demonstrate in this work is that the opposition between Husserl and Carnap cannot be interpreted either in terms of “phenomenology” and “analytical philosophy” or in terms of transcendental idealism, logicism and phenomenalism. In order to understand the opposition between Husserl and Carnap (and therefore, between continental and analytical philosophy), it is necessary to ask how and why, in their very first works and articles, they both conceived philosophy as a system of constitution. This leads us to give an account of Husserl’s and Carnap’s logico-mathematical models of the formal dimension of experience, and to define constitution as the elaboration of a continuous model for the discontinuity of the world – this discontinuity being given by the phenomenological and pre-constitutive description of the world. Would this imply then that topology is a suitable model for the construction of the world ?

Full textLogik är ett gammalt och kraftfullt verktyg för att föra korrekta resonemang och människor har under lång tid studerat och tillämpat olika logiska system. Dessa studier har till stor del fokuserat på logik som innefattar ett binärt sanningsbegrepp, det vill säga logik där en utsaga är antingen sann eller falsk. Givetvis är detta en väldigt begränsad vy då vi i vår vardag ofta måste värdera sanning på en betydligt mer flexibel skala. På samma sätt måste vi ofta resonera och fatta beslut utifrån information som på olika sätt kan vara osäker. En djupare förståelse för dessa otraditionella logiker är därför av stort intresse till exempel i expert-system som mekaniskt föreslår beslut utifrån osäker information. I denna monografi beskriver vi två matematiska ramverk som tillåter oss att beskriva dessa typer av otraditionella logiker och otraditionell representation av information i allmänhet. Dessa teoretiska konstruktioner är kompletterade med diskussioner relaterade till praktiska och vidare teoretiska tillämpningar. Den första av de två teoretiska konstruktionerna är en strikt kategoriteoretiskt definierad termmonad som kan beskriva termer och variabelsubstitution för en mängd olika otraditionella termkonstruktioner. Till exempel, genom monadkomposition kan vi representera flervärda mängder av termer och detta ger oss möjlighet att representera osäker information. Alternativt kan vi konstruera en termmonad som uttrycker osäkerhet på ett mer fundamental sätt genom att termernas ingående variabler och operatörer i sig kan ha associerad osäkerhet. Den andra teoretiska konstruktionen är en direkt generalisering av det matematiska ramverket "generell logik" som axiomatiserar de olika komponenter som ofta faller under logikbegreppet. I generell logik beskrivs dock dessa utifrån en traditionell vy och för att beskriva otraditionella logiker krävs därför ofta obekväma representationer. Den nämnda generaliseringen syftar därför till att förenkla konstruktionen av mer exotiska logiker inom ett ramverk som till stor del liknar generell logik.

Full textFrom ancient times to the present day, the field of logic has gained significant strength and now it actively contributes to many different areas, such as philos- ophy, mathematics, linguistic, computer science, artificial intelligence, hardware manufacture, etc. Each of these scenarios has specific needs, that range from very concrete requirements, like an efficient inference method, to more abstract theoretical properties, like a neat axiomatic system. Given this wide diversity of uses, a motley collection of formal languages has been developed. For many years, classical languages (mainly classical first order logic) were the alternative, but this assortment of applications made other types of logics also attractive in many situations. Imagine that the time for choosing a logic for some specific task arrives. How can we decide which is the one that fits best? Which properties should we look for? How can we “measure” a logic with respect to others? These are not easy questions, and there is not a general recipe one can follow. In this thesis we are just going to restrict these questions to a particular family of logics, and in that context we will investigate theoretical aspects that help to answer some of these concerns. Much can be discovered by carefully analyzing appealing cases, and our contribution will be developed having that philosophy in mind. Propositional modal logics offer an alternative to traditional languages. They can be regarded as a set of tools that allow to design logics specially tailored for specific tasks, having a fine-grained control on their expressivity. Additionally, modal logics turned out to have a good computational behavior, which proved to be quite robust under extensions. These characteristics, among others, placed modal logics as an attractive alternative to classical languages. In this dissertation we are going to present a new family of modal logics called memory logics. Traditional modal logics enables to describe relational structures from a local perspective. But what about changing the structure? We want to explore the addition of an explicit storage structure to modal logics, a mem- ory, that allows to model dynamic behavior through explicit memory operators. These operators store or retrieve information to and from the memory. Natu- rally, depending on which type of storage structure we want, and which memory operators are available, the resulting logic will enjoy different properties that are worth investigating. The thesis is organized as follows. In Chapter 1 we start by giving a brief recap of how modal logic was born, showing the different historical perspectives used to look at modal logic. Then we formally present the basic modal logic and a set of extended operators that helps grasp the modal “flavor” of some richer languages. We finish this chapter by giving a first glance of memory logics, and showing how they can help to model state when we choose to use a set as storage structure. Chapter 2 is devoted to present memory logics in detail. We show some examples that can be described by adding a set to standard relational structures, and the usual set operators to add elements and test membership. We then show some other memory operators that can be considered, and we discuss the possibility of adding constraints to the interplay between memory and modal operators. These constraints can be regarded as a way to have a finer-grained control on the logic expressivity. Since we have made changes to classical modal logics, we are interested in analyzing the impact those changes cause in the resulting logics. Therefore, the rest of this chapter presents a basic logic toolkit through which we can analyze this new family of logics. This toolkit can be seen as an outline that organizes the rest of the thesis and that allows to analyze memory logics in terms of expressivity, complexity, interpolation and proof theory. The rest of the chapters investigate each of these aspects in detail. In Chap- ters 3 and 4 we explore the expressive power of several memory logics and we study the decidability of their satisfiability problem. In the decidable cases, we determine their computational complexity. We analyze the impact of the differ- ent memory operators we consider, and how they interact. We also study other memory containers, such as a stack. Then, in Chapter 5, we analyze Craig inter- polation and Beth definability for some memory logic fragments. We also study memory logics from a proof theoretical perspective. In Chapter 6 and 7 we turn to Hilbert style axiomatizations and tableau systems, and we characterize several fragments of the memory logic family mostly using techniques borrowed from hy- brid logics. We close in Chapter 8 with some concluding remarks, open problems and directions for further research

Full textIn August 2005, British Airways took four days to resume its operations after a one day strike of one of its subcontractors. Because of the interconnection and the integration of their decision support, companies become more and more sensitive to modifications. At the same time, with new technologies such as RFID or GPS, companies are able to monitor operations in real time. In this thesis, we consider constraint satisfaction problems in a dynamic context. Indeed, for many years constraint programming has proven its efficiency to solve optimization problems (vehicle routing, scheduling,. . . ) in static contexts. However, dynamic contexts raise many difficulties. We put forward a set of tools to manage and to take unexpected events into account in a constraint programming framework. Each tool is based on a specific approach for dynamic problems (forbidden tuples, local search, explanations) and gives a different and complementary overview of dynamicity

Após uma elucidação geral sobre semânticas paraconsistentes e de primeira ordem, uma LIF particular, chamada QmbC, será caracterizada axiomaticamente. Em seguida será construída uma semÂntica que se demonstrará correta e completa para a LIF em questão. Por fim, uma série de LIFs com propriedades sintáticas interessantes serão caracterizadas axiomaticamente, e será visto como a semântica construída para QmbC pode ser estendida para todas essas lógicas.
Abstract: This dissertation aims to develop a sound and complete semantics for a class of first-order logics known as Logics of Formal Inconsistency (LFIs). After general explanation about paraconsistent and first-order semantics, a particular LFI, labeled QmbC, will be characterized by means of an axiom system. Then a sound and complete semantics for it will be constructed. Finally, a variety of LFIs having nice syntactic properties will be axiomatically defined, and it will be shown how the semantics proposed for QmbC can be extended for all these logics.

This research approaches the logicist project of the German philosopher, Frege, and what came to be named by the secondary literature as the “Context Principle”. Frege's logicist project is the thesis that Mathematics, specially Arithmetics, can be reduced to Logics, that is, the concepts of Arithmetics can be reduced to logical concepts and to logical theorem and axioms. The Context Principle is one of the three principles that Frege afirms to be basic for the development and execution of a project. Some questions arise to the reader that faces for the first time this principle: What a Mathematical thesis – the one that Arithmetics can be reduced to Logics has to do with a linguistic imposition – the one that we should never ask for the meaning of an isolated word, outside a sentence? The secondary literature seems to not come to any agreement about the questions around the context principle. Those questions conduct the methodological aspect of this research. The use of the Greek mith of Theseus and Daedalus labyrinth as a metaphor allows to understand the set of secondary literature interpretations regarding the context principle as an exegetical labyrinth that defyies the reader to come inside it and try to exit. At the end of the research considerations will be give about the fortune of the context principle in Frege's logicist project.
Esta pesquisa trata do “Projeto Logicista” do filósofo alemão Frege e do que veio a ser designado pela literatura secundária de “princípio do contexto”. O Projeto Logicista de Frege é a tese de que a Matemática, em particular a Aritmética, é redutível à Lógica, isto é, os conceitos da Aritmética podem ser redutíveis a conceitos lógicos e os teoremas a axiomas lógicos. O princípio do contexto é um dos três princípios que Frege afirma serem básicos para o desenvolvimento e execução de seu projeto. Algumas questões devem de pronto surgir ao leitor que pela primeira vez defronta-se com este princípio: o que uma tese matemática – a de que a Aritmética é redutível à Lógica tem a ver com uma imposição linguística – a de que nunca se deve perguntar pelo significado de uma palavra isoladamente, fora de uma proposição? A literatura secundária parece não chegar a nenhum acordo sobre as questões em torno do princípio do contexto. Assim, no desenvolvimento deste trabalho faremos uma revisão da literatura especializada sobre esse princípio. A utilização do mito grego do herói Teseu e do labirinto de Dédalo como metáfora permite entender o conjunto das interpretações da literatura secundária a respeito do princípio do contexto como um labirinto exegético, que desafia o leitor a adentrá-lo e tentar a sua saída. Ao final da pesquisa serão tecidas considerações sobre a fortuna do princípio do contexto no Projeto Logicista de Frege.

Resumo: Segundo a pressuposição de consistência clássica, as contradições têm um cará[c]ter explosivo; uma vez que estejam presentes em uma teoria, tudo vale, e nenhum raciocínio sensato pode então ter lugar. Uma lógica é paraconsistente se ela rejeita uma tal pressuposição, e aceita ao invés que algumas teorias inconsistentes conquanto não-triviais façam perfeito sentido. A? Lógicas da Inconsistência Formal, LIFs, formam uma classe de lógicas paraconsistentes particularmente expressivas nas quais a noção meta-teónca de consistência pode ser internalizada ao nível da linguagem obje[c]to. Como consequência, as LIFs são capazes de recapturar o raciocínio consistente pelo acréscimo de assunções de consistência apropriadas. Assim, por exemplo, enquanto regras clássicas tais como o silogismo disjuntivo (de A e {não-,4)-ou-13, infira B) estão fadadas a falhar numa lógica paraconsistente (pois A e (nao-A) poderiam ambas ser verdadeiras para algum A, independentemente de B), elas podem ser recuperadas por uma LIF se o conjunto das premissas for ampliado pela presunção de que estamos raciocinando em um ambiente consistente (neste caso, pelo acréscimo de (consistente-.A) como uma hipótese adicional da regra). A presente monografia introduz as LIFs e apresenta diversas ilustrações destas lógicas e de suas propriedades, mostrando que tais lógicas constituem com efeito a maior parte dos sistemas paraconsistentes da literatura. Diversas formas de se efe[c]tuar a recaptura do raciocínio consistente dentro de tais sistemas inconsistentes são também ilustradas Em cada caso, interpretações em termos de semânticas polivalentes, de traduções possíveis ou modais são fornecidas, e os problemas relacionados à provisão de contrapartidas algébricas para tais lógicas são examinados. Uma abordagem formal abstra[cjta é proposta para todas as definições relacionadas e uma extensa investigação é feita sobre os princípios lógicos e as propriedades positivas e negativas da negação.
Abstract: According to the classical consistency presupposition, contradictions have an explosive character: Whenever they are present in a theory, anything goes, and no sensible reasoning can thus take place. A logic is paraconsistent if it disallows such presupposition, and allows instead for some inconsistent yet non-trivial theories to make perfect sense. The Logics of Formal Inconsistency, LFIs, form a particularly expressive class of paraconsistent logics in which the metatheoretical notion of consistency can be internalized at the object-language level. As a consequence, the LFIs are able to recapture consistent reasoning by the addition of appropriate consistency assumptions. So, for instance, while classical rules such as disjunctive syllogism (from A and (not-A)-or-B, infer B) are bound to fail in a paraconsistent logic (because A and (not-.4) could both be true for some A, independently of B), they can be recovered by an LFI if the set of premises is enlarged by the presumption that we are reasoning in a consistent environment (in this case, by the addition of (consistent-/!) as an extra hypothesis of the rule). The present monograph introduces the LFIs and provides several illustrations of them and of their properties, showing that such logics constitute in fact the majority of interesting paraconsistent systems from the literature. Several ways of performing the recapture of consistent reasoning inside such inconsistent systems are also illustrated. In each case, interpretations in terms of many-valued, possible-translations, or modal semantics are provided, and the problems related to providing algebraic counterparts to such logics are surveyed. A formal abstract approach is proposed to all related definitions and an extended investigation is carried out into the logical principles and the positive and negative properties of negation.
