Los desacuerdos acerca de la ontología científica han sido frecuentemente reconstruidos como el resultado de una disputa entre stances epistémicas rivales. En el presente trabajo, (i) caracterizamos algunos de estos desacuerdos como desacuerdos profundos. Además, (ii) mostramos que los desacuerdos profundos sobre ontología científica pueden surgir no solo de la adopción de diferentes stances epistémicas, sino entre posiciones que se encuadran dentro de una misma stance. El desarrollo de ese punto nos permite, a su vez, establecer una distinción entre tipos (...) de desacuerdos profundos y explorar la posibilidad de que existan diferencias de grado entre ellos.

Ontological pluralism is the view that there are different ways to exist. It is a position with deep roots in the history of philosophy, and in which there has been a recent resurgence of interest. In contemporary presentations, it is stated in terms of fundamental languages: as the view that such languages contain more than one quantifier. For example, one ranging over abstract objects, and another over concrete ones. A natural worry, however, is that the languages proposed by the pluralist (...) are mere notational variants of those proposed by the monist, in which case the debate between the two positions would not seem to be substantive. Jason Turner has given an ingenious response to this worry, in terms of a principle that he calls ‘logical realism’. This paper offers a counter-response on behalf of the ‘notationalist’. I argue that, properly applied, the principle of logical realism is no threat to the claim that the languages in question are notational variants. Indeed, there seems to be every reason to think that they are. (shrink)

This paper argues that we should solve paradoxes for propositions (such as the Russell–Myhill paradox) in essentially the same way that we solve Russellian paradoxes for sets. That is, the standard, iterative approach to sets is extended to include properties, and then the resulting hierarchy of sets and properties is used to construct propositions. Propositions on this account are structured in the sense of mirroring the sentences that express them, and they would seem to serve the needs of philosophers of (...) language and metaphysicians who rely on such propositions. The resulting account has limitations, comparable to those faced by the iterative approach to sets, but it is argued to be in important ways preferable to others that have been proposed. (shrink)

In this paper, I summarize Hume's moral theory as it is developed in the Treatise on Human Nature and pay particular attention to the question how evil is possible in Hume's theory.

Are there different sizes of infinity? That is, are there infinite sets of different sizes? This is one of the most natural questions that one can ask about the infinite. But it is of course generally taken to be settled by mathematical results, such as Cantor’s theorem, to the effect that there are infinite sets without bijections between them. These results settle the question, given an almost universally accepted principle relating size to the existence of functions. The principle is: for (...) any sets A and B, if A is the same size as B, then there is a bijection from A to B. The aim of the paper, however, is to argue that this question is in fact wide open: to argue that we are not in a position to know the answer, because we are not in one to know the principle. The aim, that is, is to argue that for all we know there is only one size of infinity. (shrink)

Abstract: The standard picture of rationality requires that the agent acts so as to realize her most preferred alternative in the light of her own desires and beliefs. However, there are circumstances where such an agent can predict that she will act against her preferences. The story of Ulysses and the Sirens is the paradigmatic example of such cases. In those circumstances the orthodoxy requires the agent to be ‘sophisticated’. That is to say, she should take into account her expected (...) future choices and prevent her future self to act in certain ways. She should ‘bind’ herself to a certain course of action. This is a form of causal commitment. It is generally recognized that this form of self-commitment is the only one that is available to a rational agent. Rational commitment, where the agent gives herself a reason to act in a certain way rather than making herself act in that way, is considered not feasible. In this paper, I question this verdict. I sketch the broad outlines of a model of rational commitment, which takes as its starting point Michael Bratman’s ‘planning theory’ of intention. There are two important objections against this theory (one by John Broome and one by the Dutch philosopher Govert den Hartogh.) Both criticisms claim that such a theory is a form of ‘bootstrapping’ reasons for action into existence. In the remainder of the paper, I will defend the theory against these objections. This way, I hope to establish that defending the feasibility of rational commitment is not an obvious mistake. (shrink)

This article offers a libertarian re-examination of Brazilian political history focusing mainly on the first few decades of the 19th century. The article finds two main tendencies lurking behind the various political parties and labels of the time: one, associated mainly with the Conservative Party, leaned dangerously away from the individual liberties advocated by classical liberalism and instead more toward authoritarian forms of government. The other, associated mainly with the Liberal Party, was more libertarian in nature. This article also concludes (...) that other examinations of these budding political parties fall short by overlooking a potentially authoritarian state underlying the Conservative project that dominated politics in Brazil at the time.

Metaphysically possible worlds have many uses. Epistemically possible worlds promise to be similarly useful, especially in connection with propositions and propositional attitudes. However, I argue that there is a serious threat to the natural accounts of epistemically possible worlds, from a version of Russell’s paradox. I contrast this threat with David Kaplan’s problem for metaphysical possible world semantics: Kaplan’s problem can be straightforwardly rebutted, the problems I raise cannot. I argue that although there may be coherent accounts of epistemically possible (...) worlds with fruitful applications, any such an account must fundamentally compromise the basic idea behind epistemic possibility.

A necessarily true sentence is 'brute' if it does not rigidly refer to anything and if it cannot be reduced to a logical truth. The question of whether there are brute necessities is an extremely natural one. Cian Dorr has recently argued for far-reaching metaphysical claims on the basis of the principle that there are no brute necessities: he initially argued that there are no non-symmetric relations, and later that there are no abstract objects at all. I argue that there (...) are nominalistically acceptable brute necessities, and that Dorr's arguments thus fail. My argument is an application of Gödel's first incompleteness theorem. (shrink)

The aim of the paper is to argue that all—or almost all—logical rules have exceptions. In particular, it is argued that this is a moral that we should draw from the semantic paradoxes. The idea that we should respond to the paradoxes by revising logic in some way is familiar. But previous proposals advocate the replacement of classical logic with some alternative logic. That is, some alternative system of rules, where it is taken for granted that these hold without exception. (...) The present proposal is quite different. According to this, there is no such alternative logic. Rather, classical logic retains the status of the ‘one true logic’, but this status must be reconceived so as to be compatible with (almost) all of its rules admitting of exceptions. This would seem to have significant repercussions for a range of widely held views about logic: e.g. that it is a priori, or that it is necessary. Indeed, if the arguments of the paper succeed, then such views must be given up. (shrink)

Philosophers debate about which logical system, if any, is the One True Logic. This involves a disagreement concerning the sufficient conditions that may single out the correct logic among various candidates. This paper discusses whether there are necessary conditions for the correct logic; that is, I discuss whether there are features such that if a logic is correct, then it has those features, although having them might not be sufficient to single out the correct logic. Traditional rationalist arguments suggest that (...) the necessary conditions of thought are necessary and sufficient conditions singling out the correct logical and mathematical theories. In the contemporary debate, Chalmers advocates a view along this line. Jago, analogously, suggests that the necessary conditions for thought—or, as he calls them, our basic epistemic expectations—single out a family of logical and mathematical theories. Warren and Williamson, on the other hand, argue that there are no necessary conditions of thought. I argue that there are necessary conditions for thought, and these are necessary but not sufficient conditions to be the correct logic; indeed, these are features that all logics—correct or incorrect—share. No view we can understand is ruled out by the necessary conditions for thought, but we cannot understand quite any view. Human linguistic and conceptual abilities are genetically constrained, and these constraints are our best guide to the boundaries of logic. Arguing for this, I tackle two dogmas of modern rationalism: namely, the view that the biological constraints of human cognition have no bearing on the boundaries of the epistemic space, and the view that the boundaries of thought coincide with the boundaries of language.

Kripke [1975] gives a formal theory of truth based on Kleene's strong evaluation scheme. It is probably the most important and influential that has yet been given—at least since Tarski. However, it has been argued that this theory has a problem with generalized quantifiers such as All—that is, All ϕs are ψ—or Most. Specifically, it has been argued that such quantifiers preclude the existence of just the sort of language that Kripke aims to deliver—one that contains its own truth predicate. (...) In this paper I solve the problem by showing how Kleene's strong scheme, and Kripke's theory based on it, can in a natural way be extended to accommodate the full range of generalized quantifiers.

In his article Banicki proposes a universal model for all forms of philosophical therapy. He is guided by works of Martha Nussbaum, who in turn makes recourse to Aristotle. As compared to Nussbaum’s approach, Banicki’s model is more medical and less based on ethical argument. He mentions Foucault’s vision to apply the same theoretical analysis for the ailments of the body and the soul and to use the same kind of approach in treating and curing them. In his interpretation of (...) philosophical therapy, there are, however, some controversial issues, to which we would like to call attention: -/- Is restoring health by a philosophical method of treatment – health understood as a person’s ability to reach his/her vital goals – a convincing explication of philosophical therapy in general? In order to answer this question, it may be useful to look at Plato. It is not only Platonism (and especially Neo-platonism since Plotinus) that questions the idea that therapy is necessarily connected with „vital goals“. Buddhist and Gnostic philosophies are questioning „the vital“ in general. The immense effort in the history of philosophy to liberate the mind from the body casts doubt on the project to explain philosophical therapy solely in analogy to medical therapy. -/- According to Banicki a therapeutic philosophy has to identify the diseases it attempts at curing. There are, however, reasons for associating the term therapy with suffering/risk rather than disease. If a therapy aims at reducing the fear of death, as for example many classical philosophical therapies do, then there is no disease to be cured. A model based on chances and risks also has the advantage that the Buddhist and Stoic reinterpretation of desires/emotions as “diseases” can be dropped in contemporary philosophical therapy. -/- Banicki mentions the comparison of therapies as one of the primary goals of modelling. Methods should be verified by a statistical correlation between method and therapeutic success and/or by a theory which justifies the method. Some forms of therapies, however, avoid theory-specific terms and concepts in favor of an unprejudiced interpretation of the patient’s statements. Others share the (Nietzschean) aspiration to explore and change measures of value. If the therapeutic process is seen as a unique phenomenon, then there can be no theory and no statistics with co-occurrences. -/- According to Banicki philosophical therapy has to describe techniques which qualify as genuinely philosophical. Techniques like maieutics and hermeneutics, however, are antique philosophical “inventions”, which were later adopted by psychotherapy. If meditation is accepted as a therapeutic tool – as it was in ancient times – then there is not only a methodical but also an emotional relation to religion. If finally, the Socratic search for a good life is seen as one of the characteristics of philosophical therapy, then delimitation even turns into a criterion for non-philosophical therapies. The search for a good life requires an interdisciplinary approach. -/- For the concretization of the formal structure, we suggest a typology of therapies, which is based on chances and risks. Such a typology has the advantage, that it can model conflicting (and even opposing) forms of therapies. The variety of therapeutic goals and methods is a consequence of the historical development towards conceptual freedom. (shrink)

Plausibly, mathematical claims are true, but the fundamental furniture of the world does not include mathematical objects. This can be made sense of by providing mathematical claims with paraphrases, which make clear how the truth of such claims does not require the fundamental existence of mathematical objects. This paper explores the consequences of this type of position for explanatory structure. There is an apparently straightforward relationship between this sort of structure, and the logical sort: i.e. logically complex claims are explained (...) by logically simpler ones. For example, disjunctions are explained by their (true) disjuncts, while generalizations are explained by their (true) instances. This would seem as plausible in the case of mathematics as elsewhere. Also, it would seem to be something that the anti-realist approaches at issue would want to preserve. It will be argued, however, that these approaches cannot do this: they lead not merely to violations of the familiar principles relating logical and explanatory structure, but even to reversals of these. That is, there are cases where generalizations explain their instances, or disjunctions their disjuncts. (shrink)

Fichte assigns ‘intellectual intuition’ a new meaning after Kant. But in 1799, his doctrine of intellectual intuition is publicly deemed indefensible by Kant and nihilistic by Jacobi. I propose to defend Fichte’s doctrine against these charges, leaving aside whether it captures what he calls the ‘spirit’ of transcendental idealism. I do so by articulating three problems that motivate Fichte’s redirection of intellectual intuition from being to acting: (1) the regress problem, which states that reflecting on empirical facts of consciousness leads (...) only to further facts and so cannot yield a first principle; (2) the rhapsody problem, which states that the categories form a haphazard set and so lack necessity unless they derive from a first principle; and (3) the nihilism problem, which states that a first principle cannot lie outside our cognition of it, lest it be the cause of our cognition and, being first, the cause of all our actions, reducing us to machines. Crucially, Fichte’s three motivating problems are in fact aspects of a single problem. Leaving any aspect unsolved spoils putative solutions to the other two. Consequently, Fichte requires a single unified solution to all three, which his doctrine of intellectual intuition provides. (shrink)

Here are two plausible ideas about belief. First: beliefs are our means of storing information. Second: if we believe something, then we are willing to use it in reasoning. But in this paper I introduce a puzzle that seems to show that these cannot both be right. The solution, I argue, is a new picture, on which there is a kind of belief for each idea. An account of these two kinds of belief is offered in terms of two components: (...) a relatively stable one, which represents our information; and a more variable one, which represents what we are taking seriously. I also consider the possibility of solving the puzzle by less radical means; and an alternative argument for the proposed account of belief in terms of considerations from desire. (shrink)

Il existe de nombreuses sources d’exigences. Certaines exigences sont normatives dans la mesure où elles impliquent des affirmations concernant ce que nous avons raison de croire, faire, désirer, etc. À ce titre, les exigences morales sont parmi les meilleures candidates. Si la morale exige que l’on tienne notre promesse, il semble que nous avons une raison de la tenir. Cependant, ce ne sont pas toutes les exigences qui sont normatives en ce sens. Le catholicisme exige que l’on assiste à la (...) messe chaque dimanche. Il ne s’ensuit pas pour autant que nous avons une raison d’y assister. Pourquoi cela? Pourquoi certaines exigences sont normatives en ce sens, mais pas d’autres? En vue de répondre à cette question, je défends la conception reasons-sensitive des exigences normatives, selon laquelle les exigences normatives sont celles et seulement celles qui sont sensibles aux raisons. Par contre, cette conception n’est pas la seule disponible. Selon ce que j’appelle la conception reasons-providing, les exigences normatives sont celles et seulement celles qui fournissent des raisons. Je soutiens que cette conception-ci est vulnérable à deux objections, ce qui nous donne raison de préférer la première. (shrink)

I argue against the interpretation of propositions as intentions and proof-objects as fulfillments proposed by Heyting and defended by Tieszen and van Atten. The idea is already a frequent target of criticisms regarding the incompatibility of Brouwer’s and Husserl’s positions, mainly by Rosado Haddock and Hill. I raise a stronger objection in this paper. My claim is that even if we grant that the incompatibility can be properly dealt with, as van Atten believes it can, two fundamental issues indicate that (...) the interpretation is unsustainable regardless: (1) it is hard to determine, without appealing to propositional intentions on pain of circularity, what intention a proof-object should be understood as a fulfillment of; (2) due to a difficult fulfillment dilemma, it is unclear, at best, what the object of an intention corresponding to a proposition is.

This is a chapter on noncognitivism in a textbook on ethics.

Can one expect religious minorities to be committed to a liberal democratic state? Can a democratic, Western, liberal state be open and safe for all – both ultra-orthodox and secular alike – and count on the allegiance of all? Does this require that religious minorities ‘hide’ their religious identity and conform to prevailing laws and customs and express their religious views and practices only in the privacy of their own homes? Or should minorities request that they receive public recognition? Ought (...) such minorities tolerate opposing views and practices on matters that are central to their faith, or should they request that these are not expressed in public? In this paper, I discuss and evaluate four possible responses to these questions. (shrink)

In the Vocation of Man, Fichte makes the striking claim that life is eternal, rational, our true being, and the final cause of nature in general and of death in particular. How can we make sense of this claim? I argue that the public lectures that compose the Vocation are a popular expression of Fichte’s pre-existing commitment to what I call immortalism, the view that life is the unconditioned condition of intelligibility. Casting the I as an absolutely self-active or living (...) power enables his philosophical account of both the intelligibility of objects and of what it means to die. This explains his characterization of the Wissenschaftslehre as a system in which ‘all is act, movement, and life’. In Sect. 1, I explain the context of Jacobi’s use of ‘caput mortuum’ as a term for the thing in itself. In Sects. 2 and 3, I reconstruct two immortalist arguments from Fichte’s Jena period. The first is that the I’s self-activity rules out the existence of the thing in itself and thereby vanquishes ‘death’s head’. The second is that, insofar as the I charges us with the moral perfection of nature, it is the final cause of our entire life, including its end. This is to say that the I puts our every moment into question, even our last. In Sect. 4, I use these immortalist arguments to interpret the striking claim from the Vocation. (shrink)

Edward Nieznanski developed in 2007 and 2008 two different systems in formal logic which deal with the problem of evil. Particularly, his aim is to refute a version of the logical problem of evil associated with a form of religious determinism. In this paper, we revisit his first system to give a more suitable form to it, reformulating it in first-order modal logic. The new resulting system, called N1, has much of the original basic structure, and many axioms, definitions, and (...) theorems still remain; however, some new results are obtained. If the conclusions attained are correct and true, then N1 solves the problem of evil through the refutation of a version of religious determinism, showing that the attributes of God in Classical Theism, namely, those of omniscience, omnipotence, infallibility, and omnibenevolence, when adequately formalized, are consistent with the existence of evil in the world. We consider that N1 is a good example of how formal systems can be applied in solving interesting philosophical issues, particularly in Philosophy of Religion and Analytic Theology, establishing bridges between such disciplines.

Throughout his career, Schelling assigns knowledge of the absolute first principle of philosophy to intellectual intuition. Schelling's doctrine of intellectual intuition raises two important questions for interpreters. First, given that his doctrine undergoes several changes before and after his identity philosophy, to what extent can he be said to “hold onto” the same “sense” of it by the 1830s, as he claims? Second, given that his doctrine of intellectual intuition restricts absolute idealism to what he calls a “science of reason”, (...) which he says cannot prove the absolute’s existence, what other doctrine does he require in order to prove this? I will answer these questions by tracing the shifts in Schelling’s doctrine of intellectual intuition from the 1790s to the 1830s and drawing out its evolving methodological role within his science of intelligibility.

The extent of the originality and relevance of Kant's ethics is undeniable. But it is not so evident the fact that the Kant's moral philosophy as a whole was not suddenly built, but it was dependent on a profound debate with the philosophical tradition, especially with the German scholastic tradition, a debate which led to the assimilation or appropriation of several of its aspects. With special regard to the history of the development of the categorical imperative, it is not possible (...) to be indifferent to the influence of the practical philosophy of the Enlightenment German philosopher and theologian, Christian August Crusius. The aim of this article is thus to try to identify, taking into account the distinction of praxis in problematic and moral and the contrast between prudence and morality, some points of intersection between the moral philosophy of Crusius and Kant in its origin.

On the classical understanding, an agent is fully excused for an action if and only if performing this action was a case of faultless wrongdoing. A major motivation for this view is the apparent existence of paradigmatic types of excusing considerations, affecting fault but not wrongness. I show that three such considerations, ignorance, duress and compulsion, can be shown to have direct bearing on the permissibility of actions. The appeal to distinctly identifiable excusing considerations thus does not stand up to (...) closer scrutiny, undermining the classical view and giving us reason to seek alternative ways of drawing the justification/excuse distinction.

This article argues that using Joseph Raz’s service conception of authority to reject philosophical anarchism can be affected by political anarchism. Whereas philosophical anarchism only denies the authority of the state, political anarchism claims that anarchism is a better alternative to the state. Raz’s theory holds that an institution has authority if it enables people to better conform with reason. I argue that there are cases where anarchism is an existing alternative to the state and better fulfils this condition. Consequently, (...) in these cases, anarchist groups and societies and not the state have legitimate authority. When anarchism is not an existing alternative to the state, the state will, under Raz’s theory, have some legitimate authority, but that authority will be limited because anarchism remains a better possible alternative to the state. To support the political anarchist claim I discuss the anarchist collectives during the Spanish civil war, which I argue are an example of anarchism as an existing alternative to the state that better fulfils Raz’s service conception and also provide suggestive evidence that anarchism is in general a better possible alternative. I also discuss the relationship between political anarchism and authority and I argue that despite some tension they are not irreconcilable. I conclude that the interesting anarchist challenge for political theorists is political not philosophical. (shrink)

In a series of papers Ladyman and Presnell raise an interesting challenge of providing a pre-mathematical justification for homotopy type theory. In response, they propose what they claim to be an informal semantics for homotopy type theory where types and terms are regarded as mathematical concepts. The aim of this paper is to raise some issues which need to be resolved for the successful development of their types-as-concepts interpretation.

Kant’s critique/doctrine distinction tracks the difference between a canon for the understanding’s proper use and an organon for its dialectical misuse. The latter reflects the dogmatic use of reason to attain a doctrine of knowledge with no antecedent critique. In the 1790s, Fichte collapses Kant’s distinction and redefines dogmatism. He argues that deriving a canon is essentially dialectical and thus yields an organon: critical idealism is properly a doctrine of science or Wissenschaftslehre. Criticism is furthermore said to refute dogmatism, by (...) which Fichte means Spinozism. Schelling repudiates Fichte’s position in his Philosophical Letters by reviving Kant’s distinction. First, ‘critique’ for Schelling names a canon that is valid for all systems—including Spinozism—and thus favours none—not even the Wissenschaftslehre. Second, Schelling coins ‘dogmaticism’ to refer to what Kant calls ‘dogmatism’: reason’s uncritical claim to doctrine. Hence, he says all systems—even Fichte’s—are susceptible to the ‘enthusiasm’ of mistaking themselves for doctrines or ‘objects of knowledge’, instead of subjectively valid ‘objects of freedom’. I reconstruct Schelling’s argument for reviving Kant’s distinction, while noting two consequences for German idealism. First, if criticism favours no system, a system’s origin cannot be an act of knowledge, e.g., intellectual intuition, but only an act of endorsement. Second, if dogmaticism entails enthusiasm, a system’s goal cannot be absolute knowledge, but only infinite striving. Hence, by retrieving Schelling’s notion of dogmaticism, we can both gain a better understanding of the Letters and register the impact of a core Kantian distinction on the German idealist project.

The concept of facticity denotes conditions of experience whose necessity is not logical yet whose contingency is not empirical. Although often associated with Heidegger, Fichte coins ‘facticity’ in his Berlin period to refer to the conclusion of Kant’s metaphysical deduction of the categories, which he argues leaves it a contingent matter that we have the conditions of experience that we do. Such rhapsodic or factical conditions, he argues, must follow necessarily, independent of empirical givenness, from the I through a process (...) of ‘genesis.’ I reconstruct Fichte’s argument by tracing the origin of his neologism, presenting his Jena critique of Kant’s rhapsodic appeal to the forms of judgment, and illustrating the Jena period’s continuity with the Berlin period’s genetic method, while noting a methodological shift whereby Fichte directs his critique against his own doctrine of intellectual intuition in order to eliminate its ‘factical terms.’. (shrink)

Fichte argues that the conclusion of Kant’s transcendental deduction of the categories is correct yet lacks a crucial premise, given Kant’s admission that the metaphysical deduction locates an arbitrary origin for the categories. Fichte provides the missing premise by employing a new method: a genetic deduction of the categories from a first principle. Since Fichte claims to articulate the same view as Kant in a different, it is crucial to grasp genetic deduction in relation to the sorts of deduction that (...) Kant offers. I propose to interpret genetic deduction as the simultaneous fulfillment of two tasks: answering the question quid facti by deriving the categories from the I and answering the question quid juris by establishing our entitlement to the categories as conditions of experience. While the second task represents Fichte’s agreement with Kant’s transcendental deduction, the first reflects his correction of Kant’s metaphysical deduction. (shrink)

In this paper, I revisit Frege's theory of sense and reference in the constructive setting of the meaning explanations of type theory, extending and sharpening a program–value analysis of sense and reference proposed by Martin-Löf building on previous work of Dummett. I propose a computational identity criterion for senses and argue that it validates what I see as the most plausible interpretation of Frege's equipollence principle for both sentences and singular terms. Before doing so, I examine Frege's implementation of his (...) theory of sense and reference in the logical framework of Grundgesetze, his doctrine of truth values, and views on sameness of sense as equipollence of assertions.

In this paper, my aim is to reconstruct, through the material presented in the handschrifter Nachlaß, Kant`s criticism to Hutcheson and to the doctrine of moral feeling in the 1770s in the so called silent decade. As we can note, this criticism generally is addressed to the fact that the doctrine of moral feeling is lacking an objective ground on which can be established a categorical conception of ethics. Moreover, I argue that in this context Kant already demonstrates, from his (...) critical position in the Reflexionen and Vorlesungen, the general lines of his mature conception on moral feeling as something strictly linked to our awareness of the law.

Infectious logics are systems that have a truth-value that is assigned to a compound formula whenever it is assigned to one of its components. This paper studies four-valued infectious logics as the basis of transparent theories of truth. This take is motivated as a way to treat different pathological sentences differently, namely, by allowing some of them to be truth-value gluts and some others to be truth-value gaps and as a way to treat the semantic pathology suffered by at least (...) some of these sentences as infectious. This leads us to consider four distinct four-valued logics: one where truth-value gaps are infectious, but gluts are not; one where truth-value gluts are infectious, but gaps are not; and two logics where both gluts and gaps are infectious, in some sense. Additionally, we focus on the proof theory of these systems, by offering a discussion of two related topics. On the one hand, we prove some limitations regarding the possibility of providing standard Gentzen sequent calculi for these systems, by dualizing and extending some recent results for infectious logics. On the other hand, we provide sound and complete four-sided sequent calculi, arguing that the most important technical and philosophical features taken into account to usually prefer standard calculi are, indeed, enjoyed by the four-sided systems.

In the Freedom essay, Schelling charges that (1) idealism fails to grasp human freedom’s distinctiveness and that (2) this failure undermines idealism's attempt to refute pantheism, as exemplified by Spinoza. This raises two questions, which I will answer in turn: what, for Schelling, is distinctive of human freedom; and how does the idealists’ failure to grasp it render them unable to refute pantheism? To answer these questions, I will reconstruct Schelling’s argument that freedom has the distinctness of being the unconditioned (...) condition of the world’s intelligibility. My reconstruction will illustrate how Schelling’s notion of freedom as primal will grounds the alleged primacy of practical reason as Kant and Fichte conceive it. I will then consider three objections to Schelling’s argument. Throughout, I will develop the Schellingian idea that freedom is enacted in an unprethinkable decision that cannot be anticipated by any law or principle. (shrink)

A precursor to the hard problem of consciousness confronts nihilism. Like physicalism, nihilism collides with the first-personal fact of what perception and action are like. Unless this problem is solved, nature’s inclusion of conscious experience will remain, as Chalmers warns the physicalist, an “unanswered question” and, as Jacobi chides the nihilist, “completely inexplicable". One advantage of Kant’s Copernican turn is to dismiss the question that imposes this hard problem. We need not ask how nature is accompanied by the first-person standpoint (...) because “I think” is an apperceptive form of thinking that must be able to accompany any cognition of nature. Kant’s formal conception of apperception worries Fichte in his Nova Methodo lectures. This conception arguably cannot exhaust the ground of experience, for it does not show why we posit objects “at all". For Fichte, it is our agency that first opens a world of objects, viz., as subjects, means, ends, and obstacles. In what follows, I argue that, for Fichte, the I poses no hard problem because it collides exclusively with nihilistic views like Spinozism, which are refuted by a properly transcendental idealist conception of apperception, according to which the first-person standpoint is the absolute ground of our experience of nature. If transcendental idealism refutes nihilism, nature is no more explicable than that there is something it is like for me to perceive and act. In Section 1, I show why Kantian apperception is necessary for possible experience. In Section 2, I reconstruct Fichte’s argument that a modified conception of apperception refutes guises of nihilism, thereby solving the hard problem of consciousness. In Section 3, I suggest that transcendental idealism undermines Chalmers’ proposed solution to and Dennett’s dismissal of this problem. (shrink)

Esta edição contém a única transcrição estudantil sobrevivente das Lições de Metafísica de Kant da década de 1770. A Lição foi ministrada o mais tardar no inverno de 1779/80 e, portanto, antes mesmo da publicação da Crítica da Razão Pura (1781). Um exceção é, contudo, a parte sobre a ontologia que seguramente se remonta a uma Lição que Kant ministrou depois de 1781. Estas transcrições de Lições são de valor inestimável para a história do desenvolvimento da filosofia de Kant e, (...) em especial, para a gênese de sua Crítica da Razão Pura . Elas representam também um complemento importante para suas outras Lições, como por exemplo, as de antropologia, nas quais Kant também se ocupou com as questões da psicologia empírica e racional. É interessante observar que Kant se serve de métodos distintos, nas Lições de Antropologia e de Metafísica, para demonstrar a substancialidade e a imortalidade da alma. Embora Kant ainda leve a doutrina da alma da psicologia racional muito a sério na Metafísica-Pölitz, ele rejeitará de fato suas pretensões de conhecimento pouco tempo depois na Crítica na seção sobre os paralogismos da doutrina pura da alma. Aquele que deseja se aprofundar na filosofia de Kant e conhecer seu contexto histórico-filosófico não pode deixar de ler as Lições de Metafísica-Pölitz. Heiner F.

The article On the Miscarriage of All Philosophical Trials in Theodicy was published in 1791 on the pages of the monthly periodical berlinische Monatsschrift. By itself, the title of the article already seems to us quite enlightening. What would it be but a criticism of every attempt to justify the God's cause? Nevertheless, there are evidences that there is much more at stake. Thus, the purpose of this paper is to raise the question about the true meaning of the Kant`s (...) text, arguing in favor of the fact that, for some reasons, the essay should not be interpreted exclusively as a criticism, but otherwise as a effort to establish a positive foundation of theodicy. If, indeed, the limits of reason prohibit any attempt to defend the good cause of God by speculative means, on the other hand, practical reason opens the way, throught of the concept of a "authentic theodicy", to answer the objections which the experience raises against the government and justice of God. My purpose, from this, is to stress the important role of theodicy in the system of reason of Kantian philosophy. (shrink)

A filosofia do direito internacional de Hegel tem recebido certa atenção nos últimos anos. As pesquisas mais recentes têm buscado apresentar uma visão diferente daquela, apresentada no século XIX e primeira metade do século XX, que retratava Hegel como um entusiasta do estado de guerra. Com efeito, também se passou a reavaliar a relação de Hegel com Kant no que diz respeito às questões do direito internacional, sobretudo, a possibilidade da paz. Meu objetivo nesse artigo é, primeiramente, apresentar os aspectos (...) gerais da filosofia do direito internacional de Hegel, enfatizando seu diálogo com Kant. Tento mostrar como Hegel está, em sua discussão, em referência a importantes aspectos do texto kantiano sobre a paz perpétua. Em segunda instância, partindo desse diálogo, argumento que, embora Hegel seja certamente muito mais um crítico do projeto kantiano do que um simpatizante, as implicações últimas de seu pensamento mostram-se, em alguma medida, alinhadas com as da filosofia de Kant.

It is often claimed that the theory of function levels proposed by Frege in Grundgesetze der Arithmetik anticipates the hierarchy of types that underlies Church’s simple theory of types. This claim roughly states that Frege presupposes a type of functions in the sense of simple type theory in the expository language of Grundgesetze. However, this view makes it hard to accommodate function names of two arguments and view functions as incomplete entities. I propose and defend an alternative interpretation of first-level (...) function names in Grundgesetze into simple type-theoretic open terms rather than into closed terms of a function type. This interpretation offers a still unhistorical but more faithful type-theoretic approximation of Frege’s theory of levels and can be naturally extended to accommodate second-level functions. It is made possible by two key observations that Frege’s Roman markers behave essentially like open terms and that Frege lacks a clear criterion for distinguishing between Roman markers and function names.

I propose and defend the conjecture that what explains why Gettiered subjects fail to know is the fact that their justified true belief depends essentially on unknown propositions. The conjecture follows from the plausible principle about inference in general according to which one knows the conclusion of one’s inference only if one knows all the premises it involves essentially.

The present article aims to analyze systematically the formularization of Kant on the dignity of the human person, in order to offer a interpretative direction to the jurists at the moment of the application of this principle, which today appears as one of the beddings of the Democratic State of Law(art. 1o, III, of the Federal Constitution of 1988). To carry through such task, the work is divided in two parts: the first one studies the conceptual elements of the moral (...) philosophy of Kant, having as base the book Groundwork of the Metaphysics of Morals. The second one investigates the main aspects of the principle of the dignity of the human person - its origin, its meaning and its limits - according to the thought of this philosopher. In this perspective, the kantian's categorical imperative prescribes that the rational being never must be treated merely as a mean, but always as end in itself. (shrink)

Both patients and clinicians frequently report problems around communicating and assessing pain. Patients express dissatisfaction with their doctors and doctors often find exchanges with chronic pain patients difficult and frustrating. This chapter thus asks how we could improve pain communication and thereby enhance outcomes for chronic pain patients. We argue that improving matters will require a better appreciation of the complex meaning of pain terms and of the variability and flexibility in how individuals think about pain. We start by examining (...) the various accounts of the meaning of pain terms that have been suggested within philosophy and suggest that, while each of the accounts captures something important about our use of pain terms, none is completely satisfactory. We propose that pain terms should be viewed as communicating complex meanings, which may change across different communicative contexts, and this in turn suggests that we should view our ordinary thought about pain as similarly complex. We then sketch what a view taking seriously this variability in meaning and thought might look like, which we call the “polyeidic” view. According to this view, individuals tacitly occupy divergent stances across a range of different dimensions of pain, with one agent, for instance, thinking of pain in a much more “bodycentric” kind of way, while another thinks of pain in a much more "mindcentric” way. The polyeidic view attempts to expand the multidimensionality recognised in, e.g., biopsychosocial models in two directions: first, it holds that the standard triumvirate— dividing sensory/cognitive/affective factors— needs to be enriched in order to capture important distinctions within the social and psychological dimensions. Second, the polyeidic view attempts to explain (at least in part) why modulation of experience by these social and psychological factors is possible in the first place. It does so by arguing that because the folk concept of pain is complex, different weightings of the different parts of the concept can modulate pain experience in a variety of ways. Finally, we argue that adopting a polyeidic approach to the meaning of pain would have a range of measurable clinical outcomes. (shrink)

O termo respeito é derivado do latim respectus, que corresponde ao uso substantivo do particípio passado do verbo respicere, cujo significado literal é "olhar para trás", "olhar de volta", "olhar novamente", "considerar" (do latim re "de novo" e spicere "olhar"). Derivações do termo latino respectus são encontradas tanto no francês antigo (sec. VIII-XIX), cujo termo respit significa "descansar", "repousar", quanto no inglês médio (sec. XI-XV), cujo termo respect aparece, assumindo a função de nome, no sentido de "relação ou referência a (...) uma coisa ou situação específica" e, na função de verbo, no sentido de "ser digno de consideração ou estima". Na linguagem comum, respeito é uma das palavras cotidianas que aparece em uma multiplicidade de contextos. De um modo mais amplo, poder-se-ia definir respeito como o reconhecimento do valor e da dignidade de algo, do qual decorre um conjunto de comportamentos e estados de ânimo como resposta. Em primeira instância, é importante observar que o conceito de respeito implica sempre uma relação, como no caso em que utilizamos a locução "a respeito de". O respeito leva em conta uma relação responsiva entre sujeito e objeto na qual o sujeito responde ao objeto devido ao reconhecimento de certas características nele. Como o termo latino nos sugere, essa relação envolve um "olhar de volta" que é, ao mesmo tempo, um "considerar", ou seja, trata-se de um certo tipo de apreciação do objeto baseada em elementos tais como a atenção, o julgamento, o conhecimento, a valorização e a deferência. Nesse sentido, respeitar é uma maneira particular de se apreender objeto, na qual uma atenção especial é requerida com o propósito de reconhecer o objeto, não segundo as distorções perpetradas pela nossa subjetividade, mas em sua própria dignidade. Embora o ato de respeitar tenha origem no sujeito, ele não diz respeito primariamente ao sujeito, mas, em vez disso, ao objeto, na medida em que envolve o reconhecimento de uma propriedade que o objeto reivindica para si. Este é o motivo pelo qual respeitar não é meramente uma questão discricionária, baseada em nosso querer e não querer, mas uma experiência [...]. (shrink)

This paper presents a recent formalization of a Henkin-style completeness proof for the propositional modal logic S5 using the Lean theorem prover. The proof formalized is close to that of Hughes and Cresswell, but the system, based on a different choice of axioms, is better described as a Mendelson system augmented with axiom schemes for K, T, S4, and B, and the necessitation rule as a rule of inference. The language has the false and implication as the only primitive logical (...) connectives and necessity as the only primitive modal operator. The full source code is available online and has been typechecked with Lean 3.4.2. (shrink)

This paper argues that a necessary condition on inferential knowledge is that one knows all the propositions that knowledge depends on. That is, I will argue in support of a principle I call the Knowledge from Knowledge principle: (KFK) S knows that p via inference or reasoning only if S knows all the propositions on which p depends. KFK meshes well with the natural idea that (at least with respect to deductively valid or induc- tively strong arguments) the epistemic status (...) of one’s belief in the conclusion of an argument is a function of the epistemic status of the attitudes one has to the premises of that argument. One gets what one puts in: S’s belief in the conclusion C of an argument A has epistemic status E for S only if S’s belief in each of the premises C depends on also has epistemic status E.1 This is compatible, of course, with the epistemic status of S’s conclusion being greater than the epistemic status of the premises on which the conclusion of her reasoning depends. Furthermore, even though KFK applies more straightforwardly to non-suppositional inferences, we can also plausibly apply the principle to sup- positional reasoning if we treat S’s assuming for the sake of argument that p,2 as S assuming for the sake of argument that she knows that p.3 Although extremely plausible, philosophers have failed to present a concerted case in support of KFK. Most of their energy goes to articulating and/or defending some form of closure principle for knowledge.4 What is more, recently versions of this principle have been dismissed as problematic but I think without the reasons in its support been fully appreciated. This paper is an e fort to change the current state of affairs. Its focus is positive, however: my goal is to make the best case I can in support of KFK.5 To that end, the paper presents the reasons we have to accept KFK (§1), consid- ers an objection to the principle (§2), and situates the principle in the broader normative context of knowledge norms (§3).

Our understanding of Schelling’s internal critique of German idealism, including his late attack on Hegel, is incomplete unless we trace it to the early “Philosophical Letters on Dogmatism and Criticism,” which initiate his engagement with the problem of systematicity—that judgment makes deriving a system of a priori conditions from a first principle necessary, while this capacity’s finitude makes this impossible. Schelling aims to demonstrate this problem’s intractability. My conceptual aim is to reconstruct this from the “Letters,” which reject Fichte’s claim (...) that the Wissenschaftslehre is an unrivalled system. I read Schelling as charging Fichte with misrepresenting a system’s livability or commensurability with our finitude. My historical aim is to provide a framework for understanding Schelling’s Freiheitsschrift, which argues that a system’s liveability depends on its incompleteness or limitation by our finitude. On my reading, Schelling is early and continually committed to systematicity within the bounds of human finitude. (shrink)

Philosophical discussions of Molyneux's problem within contemporary philosophy of mind tend to characterize the problem as primarily concerned with the role innately known principles, amodal spatial concepts, and rational cognitive faculties play in our perceptual lives. Indeed, for broadly similar reasons, rationalists have generally advocated an affirmative answer, while empiricists have generally advocated a negative one, to the question Molyneux posed after presenting his famous thought experiment. This historical characterization of the dialectic, however, somewhat obscures the role Molyneux's problem has (...) played in spawning debates within the empiricist tradition. Fortunately, the differences between various empiricist accounts have been widely recognized and discussed among historians of philosophy working on the topic. The focus of the present essay is to develop an interpretation of John Locke's views on Molyneux's problem that best coheres with his other views on human understanding as well as with the predominant scientific opinion about the nature of perception during the period in which he lived.

This paper will be concerned with the role acquaintance plays in contemporary theories of introspection. Traditionally, the relation of acquaintance has been conceived in analytic epistemology and philosophy of mind as being only epistemically relevant inasmuch as it causes, or enables, or justifies a peculiar kind of propositional knowledge, i.e., knowledge by acquaintance. However, in recent years a novel account of the role of acquaintance in our introspective knowledge has been offered. According to this novel constitutive approach, acquaintance is, in (...) itself, a sui generis—i.e., non-propositional—kind of knowledge. As we will suggest, a stalemate between David Chalmers’ account of direct phenomenal concepts—as a prototypical example of a causal view—and Anna Giustina’s account of primitive introspection—as a prototypical example of a constitutive view—is looming in the current controversy between the two families of theories. Towards the end of the essay, we will point to some possible ways for a constitutive theorist to break the stalemate. (shrink)

Em 1795, a maneira sarcástica com a qual Kant inaugura um de seus textos mais influentes referindo-se ao letreiro de uma pousada holandesa sobre o qual está pintado um cemitério cujo lema é a “paz perpétua”, diz muito sobre a situação permanente de guerra em que se encontrava não só os países europeus daquele tempo, mas também, de um modo geral, os povos na história da humanidade. Com o objetivo de colocar um fim definitivo em todas as guerras, Kant propõe (...) os fundamentos de uma teoria integral do direito público tripartida nos âmbitos do 1) direito do Estado, 2) do direito das gentes e 3) do direito cosmopolita. Exige-se, na primeira esfera, a instituição da constituição republicana, o que deve tornar os Estados sistemas políticos representativos. Em relação à segunda esfera, os Estados republicanos devem se reunir em uma liga livre de povos contrária à guerra E, na última, os seres humanos devem ser reconhecidos como cidadãos do mundo, o que lhes garante um direito à hospitalidade. Não é de se surpreender, levando em conta estas inovações, que o opúsculo kantiano “À paz Perpétua” tenha se tornado tão rapidamente popular e que a sua influência tenha se estendido para o contexto jurídico-político do século XX, materializando-se no aparecimento de organizações internacionais como a Liga das Nações (1919) e a Organização das Nações Unidas (1945).
