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.

I discuss problems with Martin-Löf's distinction between analytic and synthetic judgments in constructive type theory and propose a revision of his views. I maintain that a judgment is analytic when its correctness follows exclusively from the evaluation of the expressions occurring in it. I argue that Martin-Löf's claim that all judgments of the forms a : A and a = b : A are analytic is unfounded. As I shall show, when A evaluates to a dependent function type (x : (...) B) → C, all judgments of these forms fail to be analytic and therefore end up as synthetic. Going beyond the scope of Martin-Löf's original distinction, I also argue that all hypothetical judgments are synthetic and show how the analytic-synthetic distinction reworked here is capable of accommodating judgments of the forms A type and A = B type as well. Finally, I consider and reject an alternative account of analyticity as decidability and assess Martin-Löf's position on the analytic grounding of synthetic judgments. (shrink)

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.

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. Klemme Martin-Luther-Universität Halle-Wittenberg. (shrink)

No centro da filosofia moral de Kant está sem dúvida sua doutrina do imperativo categórico. Por esse motivo não é de se surpreender que a Fundamentação da Metafísica dos Costumes (1785), na qual Kant explica, em detalhes, essa doutrina pela primeira vez, tenha sido o foco da atenção por décadas. Mas há alguns anos é observável uma significativa mudança na literatura que é univocamente bem vinda: ao lado da pesquisa das Doutrinas da Virtude e do Direito publicadas por Kant nos (...) anos noventa do século 18, agora também são intensamente estudadas suas perspectivas filosófico-morais desenvolvidas antes de 1781. Nesse sentido assume uma posição de destaque o manuscrito estudantil de uma lição de ética ministrada no meio dos anos 70, que é publicada aqui, em língua portuguesa, pela primeira vez em uma tradução comentada. Ainda hoje, esta lição serve como uma introdução à ética de Kant, muito embora pareça divergir, em alguns aspectos, da doutrina crítica do imperativo categórico. As Lições de Ética são um „trabalho em andamento“. Por um lado, somos capazes de assistir Kant "pensando" e compreender como ele se reporta ao livro de Alexander Baumgarten sobre os Príncípios da Metafísica Prática (Initia philosophiae practicae primae, 1760). E, por outro lado, somos capazes de vivenciar como ele desenvolve suas próprias perspectivas filosófico-morais em contraste a Baumgarten. Para todos que se interessam pela filosofia moral de Kant e pela história da ética na época da Aufklärung, o estudo desse manuscrito é indispensável. -/- Heiner F. Klemme (Martin Luther Universität - Halle-Wittenberg) . (shrink)

In this paper I examine the relationship between phenomenology and metaphysics by reassessing the relationship between phenomenological and metaphysical transcendence. More specifically, I examine the notion of phenomenological transcendence in Husserl and the early Heidegger: Husserl defines transcendence primarily as the mode of givenness of phenomena that do not appear all at once, but must be given in partial profiles; Heidegger defines transcendence primarily as Dasein’s capacity to go beyond entities toward being. I argue that these divergent understandings of phenomenological (...) transcendence have resulted in a significant difference in reception among French phenomenologists of religion. These thinkers assert that phenomenology, when properly conceived and utilized, can make room for the divine and its revelation, i.e., for a metaphysical transcendence. I further argue that these thinkers prefer Heidegger’s phenomenology to Husserl’s because they understand Heidegger’s transcendence as the subject’s openness to being, while they understand Husserl’s transcendence as a limit, as the inability to capture worldly objects. I take up Jean-Luc Marion’s phenomenology of givenness as a “case study” to illustrate this point. Finally, I argue that this preference for Heidegger over Husserl is misplaced and should be reversed. A close reading of Heidegger’s Phenomenology of Religious Life shows that Dasein is confined to its own possibilities and cannot be open to a relationship with the divine. By contrast, Husserl’s phenomenology provides the radical openness necessary to welcome revelation. While Husserl cannot envision a “worldly God,” the structures of horizonality and temporality characterize a subject capable of an authentic openness to revelation. (shrink)

RESUMO A alimentação é o fator que mais onera um sistema de produção animal. Assim, a utilização de diferentes estratégias de alimentação dos animais ainda é o grande desafio da nutrição animal, principalmente, levando em consideração as exigências nutricionais de diferentes categorias de ruminantes, em especial bovinos em regiões tropicais, haja vista que a sazonalidade na produção de forragens afeta diretamente a produção bovina, promovendo inadequação no atendimento das exigências nutricionais dos animais principalmente em minerais e vitaminas. Uma alimentação que (...) não atenda as exigências nutricionais dos ruminantes gera prejuízos no sistema de produção, além de, em casos mais graves, ocasionar a perda do animal. Estudos que abordam o efeito e a importância de vitaminas e minerais na nutrição bovina são escassos e necessários. Recentemente a National Research Council (NRC) apresentou novos registros das exigências nutricionais das vitaminas e minerais. Essas alterações proporcionam um impacto econômico significativo em relação à nutrição animal. Nesse sentido, objetivou-se com esta revisão trazer informações acerca de vitaminas e minerais na nutrição de bovinos em pastejo. -/- Palavras-chave: Alimentação animal; forragem; pastagem; requerimentos nutricionais; ruminantes; vitaminas lipossolúveis (Source: AGROVOC). -/- ABSTRACT Animal feed is the factor that most burdens a production system. Thus, the use of different animal feeding strategies is still the great challenge of animal nutrition, taking into account the nutritional requirements of different categories of ruminants, especially cattle in tropical regions, given that seasonality in forage production directly affects cattle production, promoting inadequacy in meeting the nutritional requirements of animals, mainly in minerals and vitamins. A diet that does not meet the nutritional requirements of ruminants generates losses in the production system, in addition to, in more serious cases, causing the loss of the animal. Studies that address the effect and importance of vitamins and minerals in bovine nutrition are scarce and necessary. Recently the National Research Council (NRC) presented new records of the nutritional requirements of vitamins and minerals. These changes provide a significant economic impact on animal nutrition. In this sense, the objective of this review was to bring information about vitamins and minerals in the nutrition of grazing cattle. -/- Keywords: Animal feeding; fat soluble vitamins; forage; nutritional requirements; pasture feeding; ruminants (Source: AGROVOC). -/- REFERÊNCIAS BIBLIOGRÁFICAS -/- 1.

IL MOSTRO E L'EROE. Quando Pomponio Algieri da Nola, all’età di soli 24 anni, viene bruciato vivo a Roma in piazza Navona, Giordano Bruno di anni ne ha appena otto. Oltre che per la giovane età del condannato, l’esecuzione è insolita anche per il luogo e il metodo scelto dall’Inquisizione: anziché le solite fascine, per alimentare il fuoco viene approntato un pentolone di pece, olio e trementina, nel quale viene immersa la povera vittima.

In Brazil, the social demand for veterinary expertise is growing. However, there is still a shortage of professionals trained in this area to apply specific knowledge to each case. Studies and research into forensic veterinary medicine are necessary for veterinary experts to assist in investigations and legal proceedings. Veterinary medicine has subjects on its curriculum that cover the knowledge needed to apply in the fields of animal health, public health and the environment. The interaction between human and veterinary medicine, as (...) well as other areas of health, is of great importance in the prevention and control of various diseases, both in animals and humans. Some cases of infectious bovine abortion have a major impact not only on cattle farming and animal health, but also on public and environmental health. The concept of "One Health" integrates human medicine and health professionals. In this context, knowledge of infectious abortive diseases that affect animal, human and environmental health is fundamental. Cattle are affected by specific infectious abortive diseases, caused by pathogens with different forms of presentation and transmission mechanisms. These include brucellosis, leptospirosis and listeriosis, which are potentially zoonotic diseases. Controlling these diseases can contribute to effective public health actions and reduce global health risks. In order to establish the diagnosis of these diseases, it is essential to properly collect specimens from live or dead animals under biosafety and biosecurity conditions, following the chain of custody for each case. These procedures allow for greater success in diagnosing the suspected agent and facilitate the investigation of other causes. Animal health standards for the prophylaxis and control of these diseases are established by specific legislation, including those of the Ministry of Agriculture, Livestock and Supply (MALS). This literature review was based on current knowledge on the Pubmed platform, Google Scholar, articles and textbooks. The aim of this article is to identify, understand and discuss the main infectious abortive diseases of cattle in the legal and forensic context, which have an impact on cattle farming, animal health, food safety, public and environmental health. -/- Referências bibliográficas Abdullah, N.

It is a well-worn platitude that knowledge excludes luck. According to anti-luck virtue epistemology, making good on the anti-luck platitude requires an explicit anti-luck condition along the lines of safety: S knows that p only if S’s true belief that p could not have easily been mistaken. This paper offers an independent, virtue epistemological argument against the claim that safety is a necessary condition on knowledge, one that adequately captures the anti-luck platitude. The argument proceeds by way of analogy. I (...) focus on two paradigmatic kinds of normative achievements that also exclude luck: (i) – having a doxastically justified belief, and (ii) – performing a morally worthy action. I then show that while (i) and (ii) exclude luck, they are nevertheless susceptible to what I call ‘modal luck’. I then move on to show that knowledge, or at least some instance of knowledge, is a normative achievement, which I claim provides strong reasons to expect that knowledge is also susceptible to modal luck. Since safety entails that knowledge is incompatible with modal luck, the argument provides strong reasons to reject safety as a necessary condition on knowledge. (shrink)

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)

This paper primarily focuses on a pivotal argument within "The Great Learning" between Chu Hsi and Wang Yang-ming. Specifically, this argument revolves around whether one should prioritize investigating things before cultivating the sincerity of will or vice versa. In simpler terms, does genuine sincerity need to precede the exploration of a matter one deeply cares about, or does sincerity naturally evolve due to the initial investigation of the issue? Through thoroughly exploring various issues stemming from Chu Hsi's perspective, I contend (...) that Wang Yang-ming's stance, asserting that the sincerity of one's will should precede the investigation of things, appears more compelling than Chu Hsi's viewpoint. Furthermore, I extend this argument to draw parallels with Śaṅkara's "A Thousand Teachings," which similarly underscores the necessity of sincerity of will preceding the examination of matters, given Śaṅkara's stringent criteria for his students.

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)

This chapter intervenes in recent debates in Kant scholarship about the possibility of a general logical alien. Such an alien is a thinker whose laws of thinking violate ours. She is third-personal as she is radically unlike us. Proponents of the constitutive reading of Kant’s conception of general logic accordingly suggest that Kant rules out the possibility of such an alien as unthinkable. I add to this an often-overlooked element in Kant’s thinking: there is reason to think that he grants—and (...) in fact presupposes—the possibility of a transcendental logical alien. Such an alien is a knower whose laws of experience purport to violate ours. She is first-personal as she is radically like us. In other words, she is us, insofar as we are alienated from ourselves and our experience. I go on to draw an analogy between her, a dogmatist, and another transcendental alien, an evil agent. Just as a dogmatist is alienated from her (our) experiential laws, an evil agent is alienated from her (our) moral law. These forms of theoretical and practical self-conceit require self-knowledge in the form of a critique of speculative or practical reason. In bringing this point out, I aim to shift from the question of whether logical laws constitute our thinking to the question of whether grasping our experiential and moral laws as our laws constitutes our reason.

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)

Throughout Herman Hesse's "Demian," the strategic use of verbal irony is a powerful tool to shed light on Sinclair's arduous journey in navigating his immaturity and eventual growth. Sinclair's initial hesitancy to confront his callowness is evident as he cautiously explores his evolving sense of self through interactions with friends and family. He often cloaks his true feelings in indirect speech, avoiding confrontations with the consequences of his immaturity. As Sinclair matures, he finds himself straddling the delicate balance between the (...) security of his familial cocoon and the intimidating outside world. He grapples with the fear that speaking his unfiltered thoughts and facing the repercussions might jeopardize the comfort of his closest relationships, guiding him on his path. Despite his awareness of the existential loneliness and isolation that awaits him beyond these relationships, he yearns for personal growth, even if it entails enduring solitude and pain. The use of verbal irony plays a pivotal role in illuminating the gradual transformation Sinclair undergoes as he shifts from callousness to a budding acceptance of his existential reality, ultimately coming to terms with his true self. This transformation is evident in moments such as when Demian chastises him for attempting to offer money to Kromer, when he grapples with the guilt of hurting Pistorius, and when his father confronts him during his time at the boarding school.

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)

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.

In his work on Gender and Salvation, Jaini delves into the intricacies of Digambara arguments and Śvētāmbara objections regarding the possibility of women attaining moksha. At the heart of this debate lies the contentious issue of attire. Both Jain sects acknowledge that Mahāvīra and his early adherent mendicants practiced nudity. However, their perspectives diverge significantly. For Digambaras, the act of going naked is considered fundamental and indispensable in the pursuit of liberation. According to their beliefs, one cannot achieve moksha without (...) embracing this practice, which is seen as a manifestation of perfection in one of the three jewels of Jainism: right conduct.

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)

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 paper argues that McDowell wrongly assumes that “terror”, Cavell’s reaction to the radical contingency of our shared modes of knowing or our “attunement”, expresses a skepticism that is antinomically bound to an equally unacceptable dogmatism because Cavell rather regards terror as a mood that reveals the “truth of skepticism”, namely, that there is no conclusive evidence for necessary attunement on pain of a category error, and that a precedent for McDowell’s misunderstanding is Hegel’s argument for necessary attunement in a (...) system of knowing, whose refutation Schelling holds it is the “merit of skepticism” to provide.

English version of collaborative text with Bruno Varela on his film La máquina de futuro (2024), published in the catalog of Umbrales experimental film section of the FICUNAM film festival.

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.

In the sixth chapter of her work “Principle,” Anne Conway advances a compelling argument in favor of the soul’s immortality. She posits that the soul, which she defines as an individual's essence, persists through time. It is noteworthy, however, that Conway also asserts elsewhere in her metaphysical discourse that her system does not necessitate the existence of immaterial entities. Consequently, she characterizes the nature of the soul as fundamentally material. This assertion raises a series of intriguing questions and challenges. One (...) commonly held assumption is that the physical body consists of matter, inherently associated with mortality due to its propensity to decay over time. Conversely, another widely accepted notion suggests a clear distinction between the soul and the body. According to this perspective, the soul is typically perceived as immaterial, lacking material substance. Given its immaterial nature, it is commonly believed to possess the attribute of immortality, as immaterial entities are thought not to succumb to the ravages of time. Thus, a perplexing conundrum arises: How can Conway reconcile her concept of a material soul with the expectation of its immortality? (shrink)

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.’.

My first aim in this paper is to use time diagrams in the style of Brentano to analyze constructions in Brouwer's separable mathematics more precisely. I argue that constructions must involve not only pairing and projecting as basic operations guaranteed by the intuition of twoity, as sometimes assumed in the literature, but also a recalling operation. My second aim is to argue that Brouwer's views on the intuition of twoity and arithmetic lead to an ontological explosion. Redeveloping the constructions of (...) natural numbers and systems sketched in an appendix to Brouwer's Cambridge lectures, I observe that the only plausible way he can make some elementary arithmetic in his separable mathematics is by allowing for the same canonical number to be determined by multiple separable entities, resulting in an overabundant mathematical ontology.

Modal phenomena in general, and modal claims in particular, present a problem for contemporary philosophers. The truth conditions of modal claims differ from those of nonemodal claims. I discuss a widely accepted strategy that posits possible and impossible worlds in order to analyze modal claims and thus systematize our intuitions about modal reality.

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)

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)

In this paper, I list various kinds of ‘plurality’ in philosophical investigations. By plurality, I mean a plurality of methodological criteria which we apply to philosophical phenomena and which are very often incompatible with each other. Any philosophical phenomenon can be approached from different methodological viewpoints and result in utterly different ontological and ideological commitments. In other words, I assume that one philosophical problem can have different solutions which depend on different methodological and theoretical presuppositions. Instead of considering this feature (...) of philosophical theories as a problem, I take this plurality as a natural meta-philosophical result. As an example, I consider impossible phenomena and ways of treating them systematically. (shrink)

The aim of this paper is to present a constructive solution to Frege's puzzle (largely limited to the mathematical context) based on type theory. Two ways in which an equality statement may be said to have cognitive significance are distinguished. One concerns the mode of presentation of the equality, the other its mode of proof. Frege's distinction between sense and reference, which emphasizes the former aspect, cannot adequately explain the cognitive significance of equality statements unless a clear identity criterion for (...) senses is provided. It is argued that providing a solution based on proofs is more satisfactory from the standpoint of constructive semantics. (shrink)

Quanto segue intende proporsi come il resoconto di una conversazione che Andrea Oliani, Bruno Cortesi e Pietro Vigiani, tutti studenti presso l’Almo Collegio Borromeo di Pavia, hanno intrattenuto con Emanuele Severino, volta ad enucleare, muovendo da spunti talvolta anche polemici, alcune delle concettualità fondanti quel corpus di dottrine che cade sotto il nome di severinismo. Severino è stato squisito nell’accoglierci e ospitarci nella sua dimora di Brescia, lucido e assolutamente puntuale nel controbattere alle nostre provocazioni. La discussione ha poi (...) trovato naturale seguito in una conferenza di carattere più divulgativo tenuta dal filosofo presso il Collegio Borromeo, dal titolo Sulla Tecnica. Severino consegue la laurea in Filosofia nel 1950 come alunno del Collegio Borromeo, discutendo una tesi intitolata Heidegger e la metafisica sotto la supervisione di Gustavo Bontadini. Solo un anno più tardi ottiene la libera docenza in filosofia teoretica. Nel 1964 pubblica lo scritto Ritornare a Parmenide, che, insieme a La Struttura Originaria rappresenta la miccia che innescherà negli anni successivi quello che molti hanno definito lo “scandalo” del severinismo. Questi scritti, come altri, posseggono una portata teorica tanto dirompente che già nel 1969, a seguito di un lungo e accurato esame condotto da Cornelio Fabro, la Chiesa cattolica proclamerà l’insanabile pposizione tra il pensiero di Severino e il Cristianesimo. Comprendere tale pensiero è cosa ardua, se prima non ci sia volti alla grecità delle origini: essa è, per Severino, il luogo ove in maniera inaudita (nel senso letterale di “mai udita prima”) viene pensato l’Incontrovertibile, il “Sempre Salvo”, ciò la cui egazione è auto-negazione, e che pertanto non può in alcun modo essere contraddetto; In altri termini: la Verità. Essa è anche stata in grado per la prima volta di concepire in maniera radicale L’Essere e il suo corrispettivo: il Niente inteso come radicale assenza di qualsiasi positività. L’aver inteso la Verità come Saphés (“Ciò che brilla di luce propria” da cui Philo-Sophìa) da un lato, e l’aver posto L’Essere e il Niente dall’altro, sono gli atti che per Severino fondano quell’immenso edificio culturale che ancora oggi domina il pianeta tutto: L’Occidente. È possibile, dunque, individuare una pars construens e una pars destruens negli scritti di Emanuele Severino: da una parte sembra che, facendo uso di un apparato logico e ontologico raffinatissimo, egli cerchi di porre in questione le categorie di pensiero occidentali risolvendo il Problema dell’Occidente alla radice, cioè eliminandolo (accenneremo a quale sia questo problema e a cosa significhi eliminarlo); in questa che è una vera e propria opera di demolizione, il Nostro (pars construens) intende mostrare come tutto quanto si mostra nell’orizzonte esperienziale sia “da sempre salvo” perché eterno. Ciò sfocia, in scritti quali Pensieri sul Cristianesimo, Technè, Il Giogo, Il Nulla e la Poesia, in una “ricostruzione” volta a mostrare come le categorie introdotte dal pensiero greco si riverberino in ogni forma della razionalità occidentale, dall’arte, alla filosofia, al diritto, alla politica, determinandone in maniera necessaria gli sviluppi. Precisiamo, per correttezza, che lo stesso non è stato rivisto da Severino. (shrink)

This paper examines how time functions as an active subject in the works of Mark Doty and Edmund de Waal, mainly through their reflections on still life and material objects. Doty’s meditations on a still life painting and De Waal’s exploration of his family’s netsuke collection reveal an inversion of our typical understanding of time, where instead of us moving through time, time itself shapes, preserves, or erodes people, places, and things. By closely observing these objects—Doty’s “things of the world” (...) and De Waal’s family heirlooms—each author recognizes how time acts upon them, turning seemingly permanent elements into transient reflections. This study argues that, in both accounts, time is a subjugating force and a silent reminder of impermanence. In this way, the paper invites readers to adopt a “close-looking” perspective, recognizing time’s invisible yet profound impact on memory, materiality, and the passage of life itself. (shrink)

During the 19th century, Emily Dickinson likely grappled with the intricate philosophical and theological responses to the metaphysical quandary of the body-soul duality. Philosophers constructed their arguments on empirical reasoning, contending that our bodies' existence equates to our existence. The soul, however, presented a challenge in terms of empirical evidence. Conversely, theologians championed the concept of the soul as an explanatory framework for the intricacies of the human mind. Their stance emphasized that just because the soul remains imperceptible does not (...) negate its existence; faith in both the soul and God was paramount. These two camps, philosophers and theologians, engaged in a spirited discourse. Theologians disapproved of what they perceived as the philosophers' reliance on mere intellectual speculation, while philosophers were disheartened by what they saw as fervent religious zealotry. Within this intellectual landscape, thinkers like Charles Peirce and William James engaged in lively debates at nearby Harvard University during Emily Dickinson's lifetime. In this paper, I argue that, in "I am Afraid to Own a Body," Emily Dickinson takes her speaker and readers on a transcendent journey, surpassing the limits of even the most eloquent philosophical discourse or theological teachings.

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)

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)

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)

Thomas Mann's "Death in Venice" is a profound fable, delivering a poignant moral lesson: suppressing one's desires can lead to distortion and an unhealthy, obsessive attachment. This, in turn, may trigger frantic and perverse attempts to obtain the initial object of desire. Aschenbach's inability to confront and satisfy his sexual urges ultimately becomes his undoing. This moral framework enables me to delve deeper into Aschenbach's actions, shedding light on the underlying animal instincts that drive his inner struggle. As a character, (...) Aschenbach embodies the archetype of the rational individual who endeavors to govern his primal, carnal urges. However, when his intellectual defenses crumble in the face of his raw desires, the battle between restraint and longing escalates into a whirlwind of uncontrollable actions. These actions catch Aschenbach off guard, and he never anticipated falling victim to them, nor did he mistrust his ability to control them. Paradoxically, he regains a semblance of control through his commitment to literary honor and morality. (shrink)

This paper examines Paul Strand’s “Swastika (a.k.a. Hitlerism)” through Robert Orsi’s concept of the holy, exploring how the swastika’s sacred origins contrast with its appropriation as a Nazi symbol. Strand’s depiction of a skeletal Christ on an inverted swastika invites reflection on the limits of reducing sacred symbols to historical associations. Drawing on Orsi’s view that the holy transcends social and historical categories, I explore how the swastika, viewed through a sacred lens, retains complex meanings beyond its Nazi connotations. Comparing (...) Strand’s work to Robert Moskowitz’s “Untitled” calls for a broader understanding of the sacred as resisting simple categorization. (shrink)

Scholars agree that Schelling’s critique of Hegel consists in charging reason with an inability to account for its own possibility. This is not an attack on reason’s project of constructing a logical system, but rather on the pretense of doing so with complete justification and so without presuppositions, as if it were obvious why there is a logical system or why there is anything meaningful at all. Scholars accordingly cite the question ‘why is there something rather than nothing’ as emblematic (...) of Schelling’s critique and the source of his claim against Hegel that reason is bounded by something other than itself. But what sort of claim is this? For what sort of argument could it be the conclusion? On these questions, the literature is lacking. I propose that the question ‘why something’ motivates Schelling to give a transcendental argument to the effect that past and future are a priori conditions of the possibility of reason. As I reconstruct it from the Weltalter, this argument construes the past as the pre-rational decision to construct a logical system, while the future represents the purpose that guides the construction of the same. Schelling’s claim against Hegel that reason is bounded by something other is thus the discovery of inescapable presuppositions that condition the possibility of reason as such. (shrink)

In the poem "Reuben Bright," the speaker initially harbors a prejudiced view of Reuben, a butcher, but this prejudice transforms into awe as the speaker observes Reuben's profound change following the death of his wife. The poem delves into the theme of loss experienced by a wife and the ensuing pain endured by her husband, resulting in a profound and shattering event that triggers significant personal growth. The central focus of the poem lies in the consequential changes that Reuben undergoes (...) as a result of this tragic event. Despite the dramatic context, the reader is guided through the poem by a distanced speaker who consistently refers to Reuben in the third person. This distancing creates two layers of separation between the reader and Reuben: one between the speaker and Reuben and another between the reader and the speaker. This sense of detachment is evident in the poem's sestet, part of an Italian sonnet, and contains symbolic imagery in the form of chopped-up cedar boughs, alluding to Reuben's spiritual transformation. Additionally, the communal change in perception of Reuben is highlighted in the only two instances where the lyric "I" of the speaker appears in the poem, emphasizing the shift in the speaker's viewpoint from prejudice towards Reuben to a profound sense of awe.

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 aim to explore the intricate interplay between slavery and the concept of evil, ultimately seeking a deeper understanding of their relationship. While critically evaluating these notions, I posit that solely relying on a historical analysis of contingent acts of evil, as proposed by Steven Mintz in his work "The Problem of Evil: Slavery, Freedom, and the Ambiguities of American Reform," falls short of providing a comprehensive moral perspective on the evil-slavery connection. To enhance the scope of (...) this thesis, I advocate for including philosophical and theological perspectives—those that Mintz attempts to exclude. Such a multifaceted approach is essential because every contingency is inherently linked to some form of necessity. By acknowledging this link, we can gain more insight into contingent acts of evil, such as slavery. Thus, a holistic understanding of the relationship between evil and slavery necessitates historical analysis and philosophical and theological explanations regarding the underlying necessities that give rise to evil.

In this paper, I contend that Socrates' four arguments for the soul's immortality fail to provide conclusive proof. Instead, these arguments can be seen as attempts to infer the most plausible explanation. However, a closer examination reveals that Socrates' best explanation relies on a sequence of informal fallacies and ambiguities, ultimately resulting in inconsistencies within his comprehensive argument. These fallacies, ambiguities, and inconsistencies will become evident as we delve into Socrates' four arguments for soul immortality in the Phaedo.
