Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / The project of naturalization of the epistemology proposed by Willard V. O. Quine it supplies a new way to do epistemology. Starting from that proposal, everything that is had to build knowledge on the world they are the sensitive evidences and the results obtained in the several scientific investigations, among them, the own empiric philosophical investigations. The naturalized epistemology doesn't intend to proceed of a privileged point of view in relation to the other sciences. For Quine that point of view is not possible, always originates from a world theory for since then, to reconstruct her revising and rejecting some beliefs. Starting from those conclusions of the quinean proposal it is noticed explicit rejection of the knowledge and justification a priori second which what would guarantee the beliefs ultimately on the world it would be a rational intuition given independently of the experience. Front to that, Laurence BonJour criticizes the project of naturalization of the epistemology proposed by Quine, because this proposal when not accepting a logic a priori would not be any reason to sustain, it would destroy yourself. This work tries to evaluate the critics of BonJour to the project of naturalization of the epistemology proposed by Quine. Intends to come a possible answer in the quinean project that there is not a logic a priori, but a naturalized reason developed starting from the experience that connects the sentences of the web. / O projeto de naturalização da epistemologia proposto por Willard V. O. Quine fornece uma nova maneira de fazer epistemologia. A partir dessa proposta, tudo o que se tem para construir conhecimentos sobre o mundo são as evidências sensíveis e os resultados obtidos nas diversas investigações científicas, entre elas, as próprias investigações filosóficas empíricas. A epistemologia naturalizada não pretende proceder de um ponto de vista privilegiado em relação às outras ciências. Para Quine esse ponto de vista não é possível, sempre se parte de uma teoria de mundo para a partir daí, reconstruí-la revisando e rejeitando algumas crenças. A partir dessas conclusões da proposta quineana percebe-se uma clara rejeição do conhecimento e justificação a priori segundo o qual o que garantiria as crenças sobre o mundo em última instância seria uma intuição racional dada independentemente da experiência. Frente a isso, Laurence BonJour critica o projeto de naturalização da epistemologia proposto por Quine, pois esta proposta ao não aceitar uma lógica a priori não teria nenhuma razão para se sustentar, seria auto-destrutiva. Este trabalho procura avaliar as críticas de BonJour ao projeto de naturalização da epistemologia proposto por Quine. Pretende-se apresentar uma possível resposta no projeto quineano de que não há uma lógica a priori, mas uma razão naturalizada desenvolvida a partir da experiência que conecta as sentenças da teia.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / In the 1960s, a debate has begun in Epistemology about a problem raised by Edmund Gettier in relation to the traditional conception of knowledge. Nowadays the cases presented by Gettier don t seem resolved what makes them even more relevant in current epistemological debates. According to these cases, some scenarios are possible in which necessary and sufficient conditions (belief, truth and justification) are satisfied in order to the traditional definition of knowledge. However, in these cases the subject (a candidate for knowledge) isn t in possession of knowledge. The mainly discussions about it are relative to the concept of epistemic justification, because justification, as an element that identifies the truth of a belief, is supposed not to be sufficient to carry on this function. This insufficiency allows, therefore, the subject be in possession of justification for her/his beliefs and, at the same time, have no knowledge yet. Gettier cases are considered a problem by some theories that defend the standard conditions to the definition of concept of knowledge. Many efforts have been tried to solve these cases with the establishment of an anti-Gettier condition to the definition of knowledge. This way of solution takes to the development of some theories of justification subjected to additional Gettier cases. Unlike this, Laurence Bonjour publishes a critic called The Myth of Knowledge, in which Gettier cases are read like some epistemological pseudoproblems. Bonjour defends that such cases and also the Lottery Paradox are introduced to Epistemology as a result of the adoption of a fallibilist view of knowledge, particularly in relation to the concept of justification. According to him, fallibilists have been failed in their efforts to solve Gettier cases and, hence, they have been complicated the possibility of a coherent concept of knowledge. Furthermore, a mistake in relation to support a fallible justification involves a myth, namely, a worthy philosophical conception of knowledge that can be found in common sense. The fallibilist view, consonant Bonjour, is philosophically unsustainable. His suggestion concerns the abandonment of the myth, because only with this way epistemological pseudoproblems would be dissolved, like those problems set by Gettier counterexamples. / Na década de 60, inicia-se um debate, no âmbito epistemológico, em torno de um suposto problema proposto por Edmund Gettier a respeito da definição tradicional de conhecimento. Até a atualidade, os casos apresentados por Gettier parecem não ter sido resolvidos, o que torna a discussão relevante nos atuais debates epistemológicos. De acordo com esses casos, é possível postular cenários em que as condições (crença, verdade e justificação) necessárias e suficientes para a definição tradicional de conhecimento são satisfeitas; entretanto, o sujeito, candidato a conhecedor, não está de posse de conhecimento. As principais discussões sobre isso ocorrem em torno do conceito de justificação epistêmica, pois se supõe que a justificação, entendida como o elemento que identifica a verdade da crença, não é suficiente para realizar essa função; permitindo, assim, situações em que o sujeito esteja de posse de justificação para suas crenças e, mesmo assim, não tenha conhecimento. Para as teorias que mantêm as condições-padrão para a definição do conceito de conhecimento, os casos de Gettier são postos como um problema, e muitas tentativas de superá-lo acontecem por meio do estabelecimento de uma condição anti-Gettier para a definição de conhecimento. Essa via de solução leva ao desenvolvimento de teorias da justificação que incorrem em adicionais casos de tipo-Gettier. Diferentemente disso, Laurence BonJour publicou uma crítica denominada O Mito do Conhecimento, em que os casos de Gettier são entendidos como pseudoproblemas epistemológicos. BonJour argumenta que tais casos, e também o Paradoxo da Loteria, são introduzidos à epistemologia como resultado da adoção de uma visão falibilista do conhecimento, particularmente com relação ao conceito de justificação. O que se evidencia é que os falibilistas têm fracassado nas tentativas de soluções para casos tipo-Gettier, e com isso inviabilizam a possibilidade de um conceito coerente de conhecimento. O equívoco da sustentação de uma justificação falível para o conhecimento radica num mito, a saber, que pode ser encontrado no senso comum uma concepção de conhecimento que seja digna de preocupação filosófica. Para BonJour essa visão falibilista do conhecimento é filosoficamente insustentável. Sua sugestão é de que se abandone o mito que a sustenta, pois somente assim se dissolveriam os pseudoproblemas epistemológicos, como aqueles engendrados pelos contraexemplos de Gettier.

There is no established standard for how Internet of Things devices are communicating with each other, every manufacturer uses their own proprietary software and protocols. This makes it difficult to ensure the best possible user experience. There are several projects that can become a standard for how devices discovering, communicating, networking etc. The goal for this thesis work was to compare such software frameworks in some areas and investigate how Inteno’s operating system Iopsys OS can be complemented by implement one of these frameworks. A literature study gave two candidates for the comparison, AllJoyn and Bonjour. The result of the comparison showed that AllJoyn was the most appropriate choice for Inteno to implement into their OS. AllJoyn was chosen because it has a potential to become an established standard and includes tools for easy implementation. To make a proof of concept, an AllJoyn application was created. The application together with a JavaScript web page, can show and control options for an AllJoyn Wi-Fi manager application and AllJoyn enabled lamps. / Det finns ingen etablerad standard för hur enheter inom Internet of Things kommunicerar med varandra. När alla tillverkare använder sina egna programvaror och protokoll, försvårar det möjligheten att skapa bästa möjliga användarvänlighet. Det finns flera projekt som utvecklar mjukvaruramverk, flera av dessa har möjligheten att bli en standard för hur enheter upptäcker, kommunicerar mm. Målet med examensarbete var att jämföra sådana mjukvaruramverk inom vissa områden samt att undersöka hur Intenos operativsystem Iopsys OS kan förbättras genom att implementera ett av dessa ramverk. En litteraturstudie gav två kandidater till jämförelsen, AllJoyn och Bonjour. Resultatet av jämförelsen visade att AllJoyn var det lämpligaste valet för Inteno att implementera i sitt operativsystem. AllJoyn valdes eftersom den har potential att bli en etablerad standard och innehåller verktyg för enkel implementering. För att bevisa konceptet, skapades ett AllJoyn-program. Programmet kan tillsammans med JavaScript generera en webbsida där användaren kan styra Wi-Fi inställningar och styra lampor via AllJoyn.

Socrates teaches in the Meno that in order for a belief to be justified, an appropriate relation must ‘tie down’ the belief to its (apparent) truth. Alvin Goldman’s position of externalism holds that for a belief to be justified, an appropriately reliable process must have obtained. One need not be aware of this reliable process. Conversely, Laurence BonJour’s brand of internalism holds that this relation between a belief and its (apparent) truth is just what the cognizer needs to be aware of in order for that belief to be justified. This work examines their debate, with particular interest paid to BonJour’s case of Norman: a clairvoyant who forms a belief via this ability but has no evidence for or against the belief or his own clairvoyance. Using this case, I propose an ‘epistemological spectrum’ wherein the insight of externalism is appreciated – what Robert Brandom deems the Founding Insight of Reliabilism – that a reliably produced belief bears some epistemic legitimacy, while retaining the insight of internalism: that objective reliability cannot offset subjective irrationality. This is done by classifying cases wherein only the obtainment of a reliable process occurs as epistemically rational, though not justified. Ultimately I reconcile the virtues of both positions, and propose that Goldman’s brand of full blooded externalism was generated by following an intuitional illusion by way of affirming the consequent.

The Internet of Things (IoT) comprises a large number of heterogeneous devices. It is forecasted that up to 50 billion devices will be connected to the Internet by 2020. All of them have to be configured. Due to the heterogeneity of devices and the enormous increasing number of devices, manual configuration becomes more and more complex and inefficient. Zero configuration is put forward to solve this problem, which makes device configured automatically without additional manual involvement. Besides that, there are many security threats we want to avoid in the future. These security problems include unauthenticated nodes accessing to IoT data, denial of service, lack of confidentiality, malicious attack from hackers and so on. This paper studies the characteristics of IoT firstly and then highlights the implementation of zero configuration and security to IoT. This paper describes the underlying features of zero configuration and primary requirements of security, as well as finds some related mature technologies, based on that proposes a concise solution – combining the Bonjour and many security approaches for implementation of a secure zero IoT system. In addition, this solution is implemented in a small environment scenario of IoT, a smart home. All the programs are in Java language. Evaluation and conclusion are done in final phase.

<p>The paper contains comment, clarification and criticism, even constructive criticism, of some theses that have been put forward by Laurence Bonjour in his In Defense of Pure Reason.</p><p>It presents a concept of experience that deals with the relation between cognizer and object of experience that has a great similarity to that of Bonjour. Through analysis it is shown that the concept of a priori entails that Bonjour has two concepts of a priori, a narrow and a broad one. The narrow one is, in my own words: According to moderate rationalism a proposition p is a priori justified if and only if you apprehend that p must be true in every possible world. This doesn’t mean that Bonjour doesn’t believe in an epistemological, metaphysical and semantic realm. The broad one does not mention anything about possible worlds.</p><p>Casullo in his A priori justification rejects Bonjour’s argument against Quine’s coherentism. A defense is put forward with the concept ‘an ideal of science for apparent rational insights’. The concept of axiomatic system and foundationalism is used. If we assume that the colour proposition ‘nothing can be red all over and green all over at the same time’ has the meaning that we, in this very moment, are representing a property in the world, thus we have an argument of superposition for the correctness of the proposition. The ground for this argumentation relies on the identification of colours with superposing electromagnetic waves.</p>
