In this article, Lucas maintains the falseness of Mechanism - the attempt to explain minds as machines - by means of Incompleteness Theorem of Gödel. Gödel’s theorem shows that in any system consistent and adequate for simple arithmetic there are formulae which cannot be proved in the system but that human minds can recognize as true; Lucas points out in his turn that Gödel’s theorem applies to machines because a machine is the concrete instantiation of a formal system: (...) therefore, for every machine consistent and able of doing simple arithmetic, there is a formula that it can’t produce as true but that we can see to be true, and so human minds and machines have to be different. Lucas considers as well in this article some possible objections to his argument: for any Gödelian formula we could, for instance, construct a machine able to produce it or we could put the Gödelian formulae that we had proved as axioms of a further machine. However - as Lucas underlines - for every of such machines we could again formulate another Gödelian formula, the Gödelian formula of these machines, that they are not able to proof but that we can recognize as true. More general arguments, such as the possibility to escape Gödelian argument by suggesting that Gödel’s theorem applies to consistent systems while we could be inconsistent ones, are moreover refuted by Lucas by maintaining that our inconsistency corresponds to occasional malfunctioning of a machine and not to his normal inconsistency; indeed, a inconsistent machine is characterized by producing any statement, on the contrary human being are selective and not disposed to assert anything.

Objective: To present a narrative review of the history of bioethics in Latin America and of scientific output in this interdisciplinary field. Methods: This was a mixed-methods study. Results: A total of 1458 records were retrieved, of which 1167 met the inclusion criteria. According to the Web of Science classification, the predominant topics of study were medical ethics, social sciences and medicine, and environmental and public health topics. Four themes of bioethics output in the Latin American literature have emerged: issues (...) involving the beginning and end of life, ethics in human research, patient–provider relationships, and ethics training for health professionals. Conclusion: Although bioethics is a growing interdisciplinary field in Latin America, its academic impact is still very low, and programmes are highly concentrated in large urban centres in a few countries. Challenges includes the regional and international impact of local scientific output. (shrink)

If we are honest, at some point we all struggle with the question, 'Why does God allow pain, suffering, and evil?'.

Davidsonian event semantics is often taken to form an unhappy marriage with compositional semantics. For example, it has been claimed to be problematic for semantic accounts of quantification Proceedings of the 16th Amsterdam Colloquium, 2007), for classical accounts of negation Semantics and contextual expression, 1989), and for intersective accounts of verbal coordination. This paper shows that none of this is the case, once we abandon the idea that the event variable is bound at sentence level, and assume instead that verbs (...) denote existential quantifiers over events. Quantificational arguments can then be given a semantic account, negation can be treated classically, and coordination can be modeled as intersection. The framework presented here is a natural choice for researchers and fieldworkers who wish to sketch a semantic analysis of a language without being forced to make commitments about the hierarchical order of arguments, the argument-adjunct distinction, the default scope of quantifiers, or the nature of negation and coordination.

Das muitas aproximações perpetradas nas últimas nove décadas entre Sigmund Freud e Espinosa, talvez nenhuma seja tão problemática quanto o cotejamento entre o conatus – esforço de perseveração no ser que, na Ética de Espinosa, constitui a essência atual das coisas – e aquela força autodestrutiva a que Freud, em Além do Princípio do Prazer, dá o nome de Todestrieb, ou pulsão de morte. De que forma, à luz de uma ontologia absolutamente positiva como a de Espinosa – uma na (...) qual a destruição de uma coisa será sempre extrínseca à mesma –, devemos receber a asserção de Freud de que há algo na constituição do sujeito que o destrói? Partindo desta questão, o intento do presente trabalho é realizar uma apresentação detida dos conceitos, a fim de determinar em que registro se dá a contradição, e até que ponto a mesma nos constrange a suprimir nossa aquiescência a um ou outro dos mesmos.

The author, who pioneered this argument in 1961, here places it in the context of traditional discussions of the problem, and answers various criticisms that have been made.

The discussion of Kant's Practical Philosophy has been marred by viewing it as purely formalist and centered only on the categorical imperative. This important new study sets out a much more vivid account of the nature and range of Kant's concerns demonstrating his commitment to the notion of rational religion and including extensive discussion of his treatment of evil. Culminating with accounts of property, the nature of right and virtue, this work presents Kant as a vital revolutionary thinker.

It is part of the current wisdom that the Liar and similar semantic paradoxes can be taken care of by the use of certain non-classical multivalued logics. In this paper I want to suggest that bivalent logic can do just as well. This is accomplished by using a non-deterministic matrix to define the negation connective. I show that the systems obtained in this way support a transparent truth predicate. The paper also contains some remarks on the conceptual interest of such (...) systems. (shrink)

Arguments have been much misunderstood. Not only has it been assumed that they must be deductive, but it has been assumed also that, although often expressed in loose and elliptical form, they must be capable, if they are valid at all, of being expressed with absolute precision, as a set of necessary and sufficient conditions for the action in question to be appropriate. Mathematical arguments are capable of being stated precisely, and it has long been a reproach to workers in (...) other disciplines that they do not manage to achieve equal precision in their work. The assumption is made that absolute precision is in principle available, and it is only a lack of rigour by practitioners in the non-mathematical disciplines that prevents them casting their arguments in satisfactory form, and the philosopher should, therefore, reconstruct arguments to conform with these requirements, evaluating those that do, and rejecting any that do not.

No hay caracterización del republicanismo que no mencione la virtud cívica. Sin embargo, no siempre es clara la ubicación de la virtud en el entramado de la filosofía política republicana. Tomaré como punto de partida la reflexión de Rawls. Su temor es que la defensa de lo que la democracia necesita, la virtud cívica, ponga en peligro la libertad. Es lo que llamaré el «problema (de Rawls) con la virtud». Un problema que, a su parecer, compromete seriamente al republicanismo. Por (...) mi parte, intentaré mostrar que, en realidad, se trata de un problema del liberalismo que apunta directamente a una bien conocida tensión entre los derechos y la democracia, cuya única «solución liberal» pasa por atrincherar los derechos «frente a la democracia», excluyendo el compromiso ciudadano. En la segunda parte mostraré que el problema es real, pero que no afecta a todos los republicanismos y argumentaré que «el problema de Rawls» afecta, fundamentalmente, a aquel republicanismo que hace de la «realización ciudadana» su objetivo, que busca, por así decir, maximizar la virtud. No sucede lo mismo con aquel otro que otorga a la virtud un carácter instrumental. En la parte final precisaré esa idea de republicanismo que otorga tanto a la virtud como a la democracia un papel instrumental en lo que realmente importa: la libertad. (shrink)

The ideal of personal autonomy enjoys considerable support in educational theory, but close analysis reveals serious problems with its core analytical and psychological components. The core conception of autonomy authorizes individuals to employ their imaginations in troubling and unhealthy ways that clash with sound ideals of moral character. Lucas Swaine argues in this essay that this gives grounds to deny that the core conception of autonomy should be promoted in democratic education. What is more, according to Swaine, young citizens (...) appear to have no right to be educated, in public schools, for the purpose of becoming autonomous individuals of the kind he describes and criticizes in this account.

Although the use of military force for humanitarian ends seems utterly divorced from the use of such force to combat terrorism, both uses answer to similar descriptions. Both appear to encourage nations that are not necessarily themselves under attack to set aside the reigning conventions of national sovereignty and territorial integrity for the overriding purposes of international law enforcement and protection of vulnerable noncombatants. Both involve offensive rather than purely defensive uses of military force. Both answer to criteria of justification (...) that can be derived more readily from the normative moral principles of the classical just war tradition than from purely descriptive revisions of the 'legalist paradigm' in international relations, because the latter is deeply wedded by precedent to notions of sovereignty, territorial integrity, and a purely defensive use of military force. Most significantly, the justification for both kinds of military action depends essentially upon a notion of 'the international community' that is inchoate and urgently in need of rigorous reformulation. In this paper, I attempt to formulate criteria for the justifiable use of military force for these non-defensive purposes, with attention to the nuances of internationalism that several of the resulting criteria entail. Challenges to the de facto role of the United Nations as the sole authoritative representative of this community, and alternatives to its authority in legitimating the use of military force for purposes of international law enforcement, are considered.

Neste trabalho discuto a natureza e a estrutura de análise da ignorância proposicional. Meu objetivo é de apontar que, em primeiro lugar, diferentemente de como ao menos duas das principais concepções da epistemologia da ignorância têm pressuposto, a análise da ignorância proposicional não se reduz a estrutura “S é ignorante que P” ou variantes semelhantes a esta estrutura. Ao lerem a ignorância proposicional reduzida em termos de “S é ignorante que P”, essas concepções não fazem a melhor análise da ignorância (...) proposicional. Isto porque, por um lado, geram um problema que se refere a uma possibilidade pouco trabalhada. Trata-se da possibilidade da ignorância sobre proposições falsas e o problema, como será mostrado, é que nessa redução há boas razões tanto para afirmar como para negar essa possibilidade. Isso se constitui, no mínimo, como uma tensão teórica relevante que pode comprometer essas concepções e as análises realizadas a partir delas. Por outro lado, essa redução exclui ao menos um sentido geral e não necessariamente factivo de ignorância proposicional, o que nos priva de uma análise mais adequada da ignorância e de outros temas relacionados. Tendo esse problema e os seus desdobramentos em vista, apontarei, em segundo lugar, para uma hipótese que tem o potencial de dissolvê-lo a partir da reformulação de como compreendemos a ignorância proposicional, herdando as vantagens das razões a favor e das razões contra a possibilidade da ignorância sobre proposições falsas e superando as objeções levantadas contra elas.

Both within its own borders and in the rest of the world, especially the Middle East, the United States is facing a growing crisis precipitated largely by the increasingly violent clash of fundamentalist religions—both among themselves and with all brands of secularism. At the center of these conflicts is the philosophical concept of the Absolute Truth: the only thing about which there is virtually total agreement among the contending parties, that is to say, almost everyone agrees that there is an (...) Absolute Truth about the way the world is and that they are in exclusive possession of it. For religious fundamentalists the Absolute Truth is their particular dogma and orthodoxy, while for Marxists it is atheistic materialism, and for Postmodernists the Absolute Truth is that there is no Absolute Truth. Needless to say, such beliefs leave virtually no room for negotiation or compromise, especially when the truth is seen as divinely ordained. Thus we find ourselves at a dangerous impasse with regard to politics and other modes of public discourse. How do we progress when everyone is right? (shrink)

El objetivo de este estudio se plantea, en términos de filosofía jurídica. la siguiente cuestión:¿Cómo debería reaccionar nuestro sistema judicial ante la presencia de otros sistemas regulativos obligatorios para grupos sociales distintos de la mayoría? Previamente el artículo erige un concepto viable de pluralismo cultural evitando los reduccionismos subyacentes: el reduccionismo que identifica pluralismo cultural con el impacto de corrientes migratorias en la Unión Europea; el reduccionismo que deriva del mantenimiento de la imposibilidad de existencia de derechos de grupo; el (...) reduccionismo que considera patológica la diversidad; el reduccionismo que equipara el pluralismo cultural con el pluralismo de valores; etc. Se llega así a la conclusión de que, en primer lugar, la cultura es conflicto, de juicio, y en segundo lugar, que la búsqueda de "una identidad cultural propia'' es un proyecto sin pretensiones. La parte final de este análisis explicita el problema en la Unión Europea y enfrenta las relaciones entre pluralismo y relativismo desde el punto de vista de la Teoría de los Derechos Humanos.

Today, bioethical themes are no longer the exclusive patrimony of university classrooms. Everyone is talking about them ; «secular» and «catholics» alike. Catholics are often accused of imposing a «confessional» point of view. This article wishes to clarify this point given its importance in themes regarding the life and death of man, such as : artificial fecundation, abortion, cloning, brain death, organ transplants, and euthanasia. The article is based on a philosophical reflection starting with anthropological considerations. The extensive number of (...) themes does not allow taking all of them into consideration. Thus the article adheres to the following outline : 1. Establish the epistemological bases for a rational discourse based on universal premises, with particular reference to artificial fecundation and the nature of human sexuality. 2. Analize the «human nature» condition of the embryo, of the physically and mentally disabled, of the terminally ill, and their status as «human persons» ; this discourse is founded on the ontological status of the human body. 3. Present the value of the human body as a psycho-biological unity, which constitutes man's substantial unity. 4. We call this psycho-biological unity «person»: «corpore et anima unus» ; an individual subject with a rational nature, with its own singularity and oneness. The person has an absolute value, therefore cloning, even for «therapeutic reasons», is contrary to its ontological status. 5. From. (shrink)

I must start with an apologia. My original paper, ``Minds, Machines and Gödel'', was written in the wake of Turing's 1950 paper in Mind, and was intended to show that minds were not Turing machines. Why, then, didn't I couch the argument in terms of Turing's theorem, which is easyish to prove and applies directly to Turing machines, instead of Gödel's theorem, which is horrendously difficult to prove, and doesn't so naturally or obviously apply to machines? The reason was that (...) Gödel's theorem gave me something more: it raises questions of truth which evidently bear on the nature of mind, whereas Turing's theorem does not; it shows not only that the Gödelian well-formed formula is unprovable-in-the-system, but that it is true. It shows something about reasoning, that it is not completely rule-bound, so that we, who are rational, can transcend the rules of any particular logistic system, and construe the Gödelian well-formed formula not just as a string of symbols but as a proposition which is true. Turing's theorem might well be applied to a computer which someone claimed to represent a human mind, but it is not so obvious that what the computer could not do, the mind could. But it is very obvious that we have a concept of truth. Even if, as was claimed in a previous paper, it is not the summum bonum, it is a bonum, and one it is characteristic of minds to value. A representation of the human mind which could take no account of truth would be inherently implausible. Turing's theorem, though making the same negative point as Gödel's theorem, that some things cannot be done by even idealised computers, does not make the further positive point that we, in as much as we are rational agents, can do that very thing that the computer cannot. I have however, sometimes wondered whether I could not construct a parallel argument based on Turing's theorem, and have toyed with the idea of a von Neumann machine. A von Neumann machine was a black box, inside which was housed John von Neumann.. (shrink)
