Rejecting the Cut rule has been proposed as a strategy to avoid both the usual semantic paradoxes and the so-called v-Curry paradox. In this paper we consider if a Cut-free theory is capable of accurately representing its own notion of validity. We claim that the standard rules governing the validity predicate are too weak for this purpose and we show that although it is possible to strengthen these rules, the most obvious way of doing so brings with it a serious (...) problem: an internalized version of Cut can be proved for a Curry-like sentence. We also evaluate a number of possible ways of escaping this difficulty. (shrink)

It is generally agreed that one of the key differences between ancient skepticism and modern and contemporary skepticism is that the ancient skeptic does not call into question the existence of the external world, but only our ability to know the properties or qualities of external objects. In this paper, I argue that in Sextus Empiricus's attack on the Epicurean criterion of truth one finds evidence that the ancient Pyrrhonist also suspends judgment about the existence of external objects.

The Pyrrhonian skeptic’s stance, as described by Sextus Empiricus, is in good part defined by his suspending judgment or belief about all the matters he has so far investigated. Most interpreters of Pyrrhonism maintain that it is a mistake to understand this form of skepticism in terms of doubt because suspension as conceived of by the Pyrrhonist is markedly different from the state of doubt. In this article, I expound the reasons that have been offered in support of that prevailing (...) view and assess their strength. (shrink)

This paper argues for the following three claims. First, the Agrippan mode from disagreement does not play a secondary role in inducing suspension of judgment. Second, the Pyrrhonist is not committed to the criteria of justification underlying the Five Modes of Agrippa, which nonetheless does not prevent him from non-doxastically assenting to them. And third, some recent objections to Agrippan Pyrrhonism raised by analytic epistemologists and experimental philosophers fail to appreciate the Pyrrhonist's ad hominem style of argumentation and the real (...) challenge posed by the mode from disagreement.

An objection that has been raised to the conciliatory stance on the epistemic significance of peer disagreement known as the Equal Weight View is that it is self-defeating, self-undermining, or self-refuting. The proponent of that view claims that equal weight should be given to all the parties to a peer dispute. Hence, if one of his epistemic peers defends the opposite view, he is required to give equal weight to the two rival views, thereby undermining his confidence in the correctness (...) of the Equal Weight View. It seems that the same objection could be leveled against those who claim to suspend judgment in the face of pervasive unresolvable disagreements, as do the Pyrrhonian skeptics. In this paper, I explore the kind of response to the objection that could be offered from a neo-Pyrrhonian perspective, with the aim of better understanding the intriguing character of Pyrrhonian skepticism.

Pyrrhonism was one of the two main ancient skeptical traditions. In this second paper of the three‐part series devoted to ancient skepticism, I present and discuss some of the issues on Pyrrhonian skepticism which have been the focus of much attention in the recent literature. The topics to be addressed concern the outlooks of Pyrrho, Aenesidemus, and Sextus Empiricus.

It is sometimes claimed that conciliatory views on disagreement ultimately lead to either global or widespread scepticism. This is deemed to be a serious problem for conciliationism either because scepticism of either kind is a patently untenable stance or because it poses a serious threat to our intellectual and social lives. In this paper, I first argue that the alleged untenability of both types of scepticism is far from being obvious and should therefore be established rather than taken for granted, (...) and then that those who reject them because of the threat they pose surprisingly confuse pragmatic reasons with epistemic reasons. (shrink)

This paper approaches the current epistemological debate on peer disagreement from a neo-Pyrrhonian perspective, thus adopting a form of skepticism which is more radical than those discussed in the literature. It makes use of argumentative strategies found in ancient Pyrrhonism both to show that such a debate rests on problematic assumptions and to block some maneuvers intended to offer an efficacious way of settling a considerable number of peer disputes. The essay takes issue with three views held in the peer (...) disagreement debate: there is an objective fact of the matter about at least most controversial questions; we possess theory-neutral evidence bearing on those questions which grants us access to the truth of the matter; and many peer controversies are resolved by attending to which disputant has correctly evaluated the objective evidence. With respect to the first two views, it is argued that the belief in both objective facts and theory-neutral evidence is subject to fierce dispute, and should not therefore be taken for granted in the discussion of peer disagreement. As for the third view, it is argued that from either a first- or a third-person perspective, there seems to be epistemic symmetry between the disputants which makes it necessary to suspend judgment.

The present paper has two, interrelated objectives. The first is to analyze the different senses in which arguments are characterized as persuasive in the extant writings of Sextus Empiricus. The second is to examine the Pyrrhonist’s therapeutic use of arguments in the discussion with his Dogmatic rivals – more precisely, to determine the sense and basis of Sextus’ distinction between therapeutic arguments that appear weighty and therapeutic arguments that appear weak in their persuasiveness.

Justice is about political ideals on how to accommodate differences that are natural among basically heterogeneous human beings. In many ways, justice is remarkably complicated because of the alleged conflict between the demands of equality and the concern that people should have as much liberty available. The author argues in this essay that the ideal of equality and liberty can be reconciled into the liberal ideal of fairness. This compromise view accounts as a justification for coercive institutions and obligations and (...) a tenable basis for a practical definition of rights and justice in general. The author does this by going through the philosophical presuppositions of the different theories of justice. His examination focuses on rendering analytic clarity to the ideal of equality, liberty, and the value of community. (shrink)

My purpose in this paper is to examine whether Pyrrhonian skepticism, as this stance is described in Sextus Empiricus’s extant works, has practical or epistemic value. More precisely, I would like to consider whether the Pyrrhonist’s suspension of judgment (ἐποχή) and undisturbedness (ἀταραξία) can be deemed to be of practical or epistemic value. By ‘practical’ value I mean both moral value and prudential value. Moral value refers to moral rightness and wrongness; prudential value to the value of well-being, personal or (...) social. Hence, when I ask whether the Pyrrhonist’s suspension and undisturbedness have practical value, I mean whether they make us behave in a manner that is morally right or wrong, and whether they allow us to attain those goals that would make it possible to live well. As for ‘epistemic’ value, it refers basically to the values of attaining truth and avoiding error. Hence, when I ask whether the Pyrrhonist’s suspension has epistemic value, I mean whether it allows us to attain truth and avoid error. My main focus will be the practical value of both suspension and undisturbedness because this is the value on which ancient philosophy scholars critical of Pyrrhonism have laid emphasis. The reason for examining the epistemic value of suspension is that doing so will enable a fuller assessment of the significance of Pyrrhonism as a kind of philosophy, which is my primary concern.

El concepto de trastorno mental permite justificar intervenciones médicas, psicológicas y judiciales. Además, facilita a la/el consultante acceder a tratamientos mediante reembolsos o programas de salud pública, y por otro lado, podría conllevar estereotipos sociales. No obstante, el significado de dicho concepto no ha dejado de suscitar debate. En el presente artículo argumentaré que los trastornos de personalidad, tal como son definidos en el DSM-5, no cumplen con los criterios de patología de las propuestas principales (i.e. teoría bio-estadística de la (...) salud, disfunción dañina, o entidad patológica) debido a tres razones independientes: (i) no se han propuesto dis/funciones a la base de cada trastorno y, dado el estado del arte de la psicología evolucionista, es poco probable que se pueda llevar a cabo ese programa en el futuro; (ii) el concepto de daño (distrés, perjuicio) aplicable a los trastornos de personalidad es constitutivamente social (aunque no exclusivamente social), por lo que resulta más adecuado hablar de grados de discapacidad que de trastornos del individuo; y (iii) que la ausencia de condiciones patognomónicas para cada trastorno, junto a la elevada comorbilidad y multimorbilidad entre trastornos de personalidad, horada la validez de la nosología actual y de los diagnósticos diferenciales. Propondré como solución la eliminación de los trastornos de personalidad de la nosología psiquiátrica. Eliminar los trastornos de personalidad no equivale a desconocer el sufrimiento de las personas diagnosticadas, ni a ignorar que dicho sufrimiento precede a, –y no acaba con la disolución de– la etiqueta diagnóstica. Por ello, se propondrá una reconceptualización de dicho sufrimiento en términos de discapacidad, entendida desde el modelo social, y que no presupone patología. (shrink)

Este trabalho tem por objetivo a compreensão da ação em Aristóteles. Para este fim será utilizado o livro III da Ética a Nicômaco, passando antes por uma breve definição da virtude, tal como aparece no livro II, a qual, pode-se dizer ser o bem para a ação, na medida em que é aquilo que se deve alcançar com ela. No campo específico da ação será visto como ela pode ser distinguida entre voluntária, involuntária e não-voluntária. Neste espectro insere-se igualmente a (...) discussão sobre o que significa agir por e na ignorância. Além disso, se abordará também a questão relacionada à deliberação e à escolha.: This study aims to understand the action in Aristotle. For this purpose, we will use the book III of the Nicomachean Ethics, after doing a brief definition of virtue, as it appears in the Book II, which can be said to be the good for the action, as that is what should be reached by her. In the specific field of action, it will be seen how she can be distinguished between voluntary, involuntary and non-voluntary. This spectrum is also part of the discussion about what it means to act by and in the ignorance. In addition, the study will also address the issue related to deliberation and choice.

Sextus Empiricus associates the skeptical stance with the activity of inquiry or investigation. My purpose in this paper is to examine the Pyrrhonist's involvement in that activity because getting an accurate understanding of the nature and purpose of skeptical inquiry makes it possible to delineate some of the distinctive traits of Pyrrhonism as a kind of philosophy. I defend the minority view among specialists according to which (i) Sextus describes both the prospective Pyrrhonist and the full-fledged Pyrrhonist as inquirers into (...) truth, and (ii) the full-fledged Pyrrhonist can, without inconsistency, engage in truth-directed inquiry.

Ancient philosophy knew two main skeptical traditions: the Pyrrhonian and the Academic. In this final paper of the three‐part series devoted to ancient skepticism, I present some of the topics about Academic skepticism which have recently been much debated in the specialist literature. I will be concerned with the outlooks of Arcesilaus, Carneades, and Philo of Larissa.

This paper engages with Svavar Svavarsson’s recent essay, “Sextus Empiricus on Persuasiveness and Equipollence,” arguing against both (i) his interpretation of whether two rival arguments appear equipollent to the Pyrrhonist because he himself is equally persuaded by both of them, and (ii) his interpretation of the way in which the argument from possible disagreement is supposed to induce suspension of judgment in the Pyrrhonist. In so doing, I aim to dispel some serious misunderstandings regarding key aspects of the Pyrrhonist’s skeptical (...) outlook and argumentative practice. (shrink)

In his account of Pyrrhonism, Sextus Empiricus talks about the disturbance concerning matters of opinion that afflicts his dogmatic rivals and that he himself was afflicted by before his conversion to Pyrrhonism. The aim of the present paper is to identify the distinct sources of doxastic disturbance that can be found in that account, and to determine whether and, if so, how they are related. The thesis to be defended is that it is possible to discern three sources of doxastic (...) disturbance and that two of them are to be explained by reference to the third, which is the real cause of mental distress. The paper also considers whether the thesis in question entails that there is no reason for the Pyrrhonist to suspend judgment across the board, but only to suspend judgment about evaluative matters. (shrink)

This paper assesses both the practical and the epistemic value of Pyrrhonism as this stance is described in Sextus Empiricus’s extant writings. It first explores whether the Pyrrhonist’s suspension of judgment and undisturbedness make us behave in a moral or immoral way, and whether they allow us to attain those goals that would make it possible to live well. It then examines whether the Pyrrhonist’s suspension of judgment makes it possible to reach the epistemic goals of attaining truth and avoiding (...) error. It finally considers whether the results of the previous analyses show that Pyrrhonism is of no philosophical interest to a contemporary audience. (shrink)

In this paper, we will motivate the application of specific rules of inference from the propositional calculus to natural language sentences. Specifically, we will analyse De Morgan’s laws, which pertain to the interaction of two central topics in syntactic research: negation and coordination. We will argue that the applicability of De Morgan’s laws to natural language structures can be derived from independently motivated operations of grammar and principles restricting the application of these operations. This has direct empirical consequences for the (...) hypothesised relations between natural language and logic. (shrink)

The purpose of the present paper is twofold. First, to examine what beliefs, if any, underlie (a) the Pyrrhonist’s desire for ataraxia and his account of how this state may be attained, and (b) his philanthropic therapy, which seeks to induce, by argument, ejpochv and ataraxia in the Dogmatists. Second, to determine whether the Pyrrhonist’s philanthropy and his search for and attainment of ataraxia are, as scholars have generally believed, essential aspects of his stance.

Proof-theoretic models of grammar are based on the view that an explicit characterization of a language comes in the form of the recursive enumeration of strings in that language. That recur-sive enumeration is carried out by a procedure which strongly generates a set of structural de-scriptions Σ and weakly generates a set of strings S; a grammar is thus a function that pairs an element of Σ with elements of S. Structural descriptions are obtained by means of Context-Free phrase structure (...) rules or via recursive combinatorics and structure is assumed to be uniform: binary branching trees all the way down. In this work we will analyse natural language constructions for which such a rigid conception of phrase structure is descriptively inadequate, and pro-pose a solution for the problem of phrase structure grammars assigning too much or too little structure to natural language strings: we propose that the grammar can oscillate between levels of computational complexity in local domains, which correspond to elementary trees in a lexicalised Tree Adjoining Grammar.

In his Pyrrhonian Outlines , Sextus Empiricus employs an argument based upon the possibility of disagreement in order to show that one should not assent to a Dogmatic claim to which at present one cannot oppose a rival claim. The use of this argument seems to be at variance with the Pyrrhonian stance, both because it does not seem to accord with the definition of Skepticism and because the argument appears to entail that the search for truth is doomed to (...) failure. In the present paper, I examine the passages in which Sextus utilizes the argument from possible disagreement and offer an interpretation that makes the use of this argument compatible with the Pyrrhonian outlook. (shrink)

My purpose in this article is to revisit an issue concerning the state of undisturbedness or tranquility (ἀταραξία) in ancient Pyrrhonism as this skeptical stance is depicted in Sextus Empiricus’s extant works. The issue in question is whether both the pursuit and the attainment of undisturbedness in matters of opinion should be regarded as defining features of Pyrrhonism not merely from a systematic standpoint that examines Pyrrhonism as a kind of philosophy, but mainly according to Sextus’s own account of that (...) skeptical stance. In exploring this issue, I will develop an interpretation defended in previous work, responding to some objections, discussing alternative interpretations, offering further textual support, and putting forward new arguments. It is my contention that examining whether both the pursuit and the attainment of undisturbedness in matters of opinion are essential to Pyrrhonism will make it possible to gain a more accurate understanding of this brand of skepticism. (shrink)

In this introductory chapter, I first offer an overview of the two themes addressed in the present collection - namely, disagreement and skepticism - and their connection, then present the purpose and content of the volume.

In this article I consider some recent objections raised against the syntactic treatment of negation in English multiclausal structures, in particular what has been called NEGraising. I argue that the objections based on pronominalisation and ellipsis presented in the recent literature do pose a problem for syntactic accounts of the mechanisms of so-called NOT-transportation that rely on a rule of leftwards movement, as is customary in generative grammar. However, there is an alternative syntactic treatment that assumes that negation originates as (...) a higher predicate and is subject to a rule of lowering. I show that a syntactic theory of NOT-transportation is tenable and accounts for the problematic data if NEGraising is replaced, in the analysis of the cases considered here, by a rule of NEG-lowering.

Scholarship on ancient skepticism has undergone a remarkable renaissance in the last three decades. Specialists in ancient philosophy have explored the complex history of the Greco‐Roman skeptical traditions and discussed difficult philological and exegetical issues. But they have also assessed the philosophical significance of the various ancient skeptical outlooks. In this first paper, I provide a general presentation of this area of study, while in the two subsequent articles I will focus on some of the topics that have been the (...) object of much attention in the recent literature on ancient skepticism.

La présente étude a deux objectifs. Le premier est d’examiner les différentes formulations de l’objection de l’ἀπραξία telle qu’elle fut soulevée contre le scepticisme académicien et le pyrrhonisme, ainsi que les réponses à cette objection proposées par Arcésilas et Sextus Empiricus. Le second objectif consiste à évaluer la force de la version de l’objection de l’ἀπραξία selon laquelle le sceptique ne peut réaliser les actions rationnelles propres à l’être humain.

In this paper, I critically engage with Casey Perin's interpretation of Sextan Pyrrhonism in his book, The Demands of Reason: An Essay on Pyrrhonian Scepticism. From an approach that is both exegetical and systematic, I explore a number of issues concerning the Pyrrhonist's inquiry into truth, his alleged commitment to the canons of rationality, and his response to the apraxia objection.

El nihilismo y el eterno retorno son conceptos centrales en el intento nietzscheano por comprender el surgimiento y la crisis de los valores, desde el advenimiento de la metafísica y la moral cristiana. Sin embargo, la valoración de estos conceptos dista de ser unívoca en la obra del filósofo alemán, ya que su sola enunciación no es suficiente para alcanzar una de las metas máximas de su pensamiento: la transvaloración. El presente artículo tiene por objetivo examinar los sentidos en los (...) que se habla de nihilismo en algunos pasajes de la obra de Nietzsche y la necesidad conceptual de llegar al pensamiento del eterno retorno como condición necesaria para efectuar la transvaloración; en este sentido, se sustentará la tesis de que el eterno retorno implica tanto la perfección como la superación del nihilismo, en la medida en que logra apartar de sí el resentimiento. Para ello, se mostrará el camino recorrido por el autor para superar la ambivalencia de la debilidad y la fuerza que acompaña el desarrollo de estos conceptos, en parte de la Ciencia Jovial y el tercer libro de Así habló Zaratustra.

The question of whether the Pyrrhonist adheres to certain logical principles, criteria of justification, and inference rules is of central importance for the study of Pyrrhonism. Its significance lies in that, whereas the Pyrrhonist describes his philosophical stance and argues against the Dogmatists by means of what may be considered a rational discourse, adherence to any such principles, criteria, and rules does not seem compatible with the radical character of his skepticism. Hence, if the Pyrrhonist does endorse them, one must (...) conclude that he is inconsistent in his outlook. Despite its import, the question under consideration has not received, in the vast literature on Pyrrhonism of the past three decades, all the attention it deserves. In the present paper, I do not propose to provide a full examination of the Pyrrhonist’s attitude towards rationality, but to focus on the question of whether he endorses the law of non-contradiction (LNC). However, I will also briefly tackle the question of the Pyrrhonist’s outlook on both the canons of rational justification at work in the so-called Five Modes of Agrippa and the logical rules of inference. In addition, given that the LNC is deemed a fundamental principle of rationality, determining the Pyrrhonist’s attitude towards it will allow us to understand his general attitude towards rationality.

The purpose of this paper is twofold: to discuss some challenging issues concerning Sextus’ works and outlook, and to offer an overview of the influence exerted by Sextan Pyrrhonism on both early modern and contemporary philosophy.

The present article proposes to study Condillac’s analysis of Spinoza’s Ethics, against the background of the more general criticism that the French abbot makes of the seventeenth-century logique de système. From the Essai sur l’origine des connaissances humaines to the Traité des systèmes to the later texts, Condillac’s theory and critique of systems are crossed by two components: on the one hand, the search for the sensory origin of ideas, that Condillac radicalizes in his Traité des sensations into a theory (...) of knowledge as a ‘transformed sensation’. On the other hand, an operative logic of signs, which from the Essai to the works subsequent to the Traité des sensations translates sensibility into a knowledge, or a ‘well-made language’, whose logic is calculation. My objective is to clarify how the new ‘systematic spirit’, repeatedly invoked by the abbot, departs from the ‘bad metaphysics’ that he claims to liquidate. The comparison with the Spinozist system will be illuminating: in his treatise on the metaphysical systems of the seventeenth century Condillac proposes a critical analysis of the ‘geometrical spirit’; in his latest work, La langue des calculs, he proposes a new logic to which he assigns the task of bringing together the abstract and the concrete, beyond the ruins of classical metaphysics. The ‘systematic spirit’ and ‘spirit of system’ will be revealed, in spite of Condillac’s efforts, as being much closer to what it appears at first sight. (shrink)

It is generally thought that suspension of judgment about a proposition p is the doxastic attitude one is rationally compelled to adopt whenever the epistemic reasons for and against p are equipollent or equally credible, that is, whenever the total body of available evidence bearing on p epistemically justifies neither belief nor disbelief in p. However, in a recent contribution to this journal, Jan Wieland proposes “to broaden the conditions for suspension, and argue that it is rational to suspend belief (...) on a certain issue even if one’s current evidence is not neutral (or even close to neutral)”. My aim in this paper is to point to a number of problems in Wieland’s position, some of which in connection with the account of Pyrrhonian skepticism found in the extant works of Sextus Empiricus.

O presente artigo analisa a propriedade privada a partir da teoria de John Locke no que se refere à aquisição originária. São discutidos o princípio da apropriação pelo trabalho, os limites à propriedade privada pelo deixar em comum para apropriação pelos demais 'o suficiente e de mesma qualidade' - o que Nozick nomeia como 'cláusula lockeana' –, bem como a possibilidade de acumulação. Para isso serão analisados os argumentos apresentados por Locke, acompanhado das críticas elaboradas por Robert Nozick.

The enactive approach to cognition and the phenomenological tradition have in common a wide conception of ‘intentionality’. Within these frameworks, intentionality is understood as a general openness to the world. For classical phenomenologists, the most basic subjective structure that allows for such openness is time-consciousness. Some enactivists, while inspired by the phenomenological tradition, have nevertheless argued that affectivity is more basic, being that which gives rise to the temporal flow of consciousness. In this paper, I assess the relationship between temporality (...) and affectivity from both a phenomenological and an enactive perspective. I argue that, as opposed to the classical phenomenological view (which favours temporality), and to the enactive view (which favours affectivity), we must take affectivity and temporality as co-emergent. Jointly, affectivity and temporality constitute the basic structures of intentionality. Additionally, using examples from phenomenological psychopathology, I conclude that all intentionality is defined by an anticipatory and affective structure that gives rise to general feelings related to our bodily possibilities in the world.

In this essay, I consider an evolutionary debunking argument (EDA) that purports to undermine the epistemic justification of the belief in the reliability of our belief-forming processes, and an evolutionary vindicating argument (EVA) that seeks to establish that such a belief is epistemically justified. Whereas the EDA in question seems to fall prey to crippling self-defeat, the EVA under consideration seems to fall prey to vicious circularity. My interest in those arguments and the problems they face lies in what they (...) might tell us about the possibly aporetic nature of reason. For, if we take the EDA and the EVA in question to consist of true or plausible premises and valid inferences at which we arrive through a meticulous use of reason, then their falling victim to either crippling self-defeat or vicious circularity might be regarded as a sign that, when we push rational reflection on the reliability, or lack thereof, of our belief-forming capacities to the limit, we end up in a situation of aporia from which there seems to be no escape.

Several scholars familiar with Sextus Empiricus’s Pyrrhonism who have attentively read his Against the Ethicists have gotten the impression that something strange is going on in this book. For, at variance with the ‘official’ Pyrrhonian attitude of universal suspension of judgment, a number of passages of Against the Ethicists seem to ascribe to the Pyrrhonist both a type of negative dogmatism and a form of realism, which together amount to what may be called ‘moderate ethical realism’. The purpose of this (...) paper is to determine whether Sextus does embrace such a position in Against the Ethicists. (shrink)

Sortition, i.e. random appointment for public duty, has been employed by societies throughout the years as a firewall designated to prevent illegitimate interference between parties in a legal case and agents of the legal system. In judicial systems of modern western countries, random procedures are mainly employed to select the jury, the court and/or the judge in charge of judging a legal case. Therefore, these random procedures play an important role in the course of a case, and should comply with (...) some principles, such as transparency and complete auditability. Nevertheless, these principles are neglected by random procedures in some judicial systems, which are performed in secrecy and are not auditable by the involved parties. The assignment of cases in the Brazilian Supreme Court is an example of such a procedure, for it is performed using procedures unknown to the parties involved in the judicial cases. This article presents a review of how sortition has been historically employed by societies and discusses how Mathematical Statistics may be applied to random procedures of the judicial system, as it has been applied for almost a century on clinical trials, for example. A statistical model for assessing randomness in case assignment is proposed and applied to the Brazilian Supreme Court. As final remarks, guidelines for the development of good randomization procedures are outlined. (shrink)

Este artigo tem por objetivo analisar se não seria o caso que o trato diferenciado dedicado a cidadãos nacionais e imigrantes seria discriminatório. A questão dos imigrantes internacionais aflora atualmente nos mais distintos campos da sociedade. Entretanto, o foco da discussão aqui não é somente o ato de cruzar as fronteiras – ponto central de grande parte das publicações filosóficas sobre imigração. O cerne é a diferença entre direitos e obrigações de imigrantes internacionais e cidadãos nacionais. Não se trata de (...) cidadãos de um ou outro país, mas da categoria ‘cidadão nacional’ frente à categoria ‘estrangeiro’, independentemente do país. Será discutido o conceito de discriminação, a fim de que, sobre o pano de fundo deste conceito, sejam debatidas as restrições aos direitos dos estrangeiros. Com isso, pretende-se demonstrar que este tratamento diferenciado caracterizaria uma discriminação, pois os argumentos que sustentariam a diferenciação são insuficientes para justificá-la. -/- This paper aims to analyze whether the differential treatment dedicated to national citizens and immigrants would be discriminatory. The issue of international migrants arises today in very different fields of society. However, the core of the discussion here is not only the act of crossing borders – focus of much of the philosophical publications about immigration. The focus of the analysis is the difference of rights and obligations between international migrants and national citizens. It is not about one country or another, but the discussion concern the category ‘national citizen’ in relation to the ‘foreign’, regardless of the country. We will discuss the concept of discrimination, in order to debate the restrictions over the rights of the strangers on the background of this conceptualization. Our goal is to show that this differential treatment would characterize as discrimination, because the arguments that support this differentiation are insufficient for justifying it. (shrink)
