In order to defend his controversial claim that observation is unaided perception, Bas van Fraassen, the originator of constructive empiricism, suggested that, for all we know, the images produced by a microscope could be in a situation analogous to that of the rainbows, which are ‘images of nothing’. He added that reflections in the water, rainbows, and the like are ‘public hallucinations’, but it is not clear whether this constitutes an ontological category apart or an empty set. In this paper (...) an argument will be put forward to the effect that rainbows can be thought of as events, that is, as part of a subcategory of entities that van Fraassen has always considered legitimate phenomena. I argue that rainbows are actually not images in the relevant (representational) sense and that there is no need to ontologically inflate the category of entities in order to account for them, which would run counter to the empiricist principle of parsimony.

Review of: "Further Chaos and Dysfunction in the Brickyard and the Systems That Support It".

This paper represents a counterreply to “A rejoinder to Alessio Gava’s ‘Van Fraassen, a inferência da melhor explicação e a Matrix realista’”, by Minikoski and Rodrigues da Silva, released in Problemata (v. 12, n. 2, 2021). The authors originally published an essay in the same journal, “Van Fraassen and inference to the best explanation” (2016), the object of critic - ‘friendly and gentle’ - in a work of mine that also appeared in Problemata, in 2019. In this paper (...) I will show that, even when the subject matter is the inference to the best explanation, realists and antirealists end up debating about the same old topics, that represent the essence of the controversy between the two philosophical stances.

Discutindo acerca das centenas de detecções de planetas extrassolares, que supostamente aconteceram desde 1989 e que ele considera (incorretamente) como instâncias de observações, Peter Kosso disse, justamente, que segundo os parâmetros de Bas van Fraassen esses objetos celestes seriam observáveis. Ora, tais astros poderiam sem dúvida ser observados diretamente (sem a necessidade de instrumentos), nas condições apropriadas. Mas, acrescenta Kosso, “esse tipo de epistemologia externalista, que permite que a justificação se baseie em informação que não temos a disposição (nós não (...) estamos em condição de ver planetas extrassolares a olho nu [atualmente]), não ajuda a decidir quais particulares afirmações científicas garantem a crença” (Kosso 2006, 225, nota 1). Van Fraassen provavelmente incorre em uma petição de princípio não muito diferente daquelas que ele muitas vezes desmascarou em textos de autores realistas, quando apela para o fato de o objeto detectado ser observável, para atribuir o estatuto de ‘observação’ a uma certa detecção. O ponto é, mais uma vez, entender o que vale como observação, particularmente quando isso envolve o uso de algum instrumento. Endossar aquilo que Otávio Bueno chama de ‘padrão internalista’ parece garantir solidez à qualificação de determinadas ações como observações. Uma das principais consequências dessa adoção é que tal critério, não operando nenhuma distinção relevante entre detecções ‘diretas’ e detecções mediadas por instrumentos, permite que a linha que separa observáveis e inobserváveis seja traçada de maneira diferente de como van Fraassen acredita que deveria ser, abarcando, entre os observáveis, mais (tipos de) entidades do que esse parece estar disposto a admitir.

Aspetti filosofico-matematici dei celebri paradossi di Zenone di Elea.

The concept of observability is of key importance for a consistent defense of Constructive Empiricism. This anti-realist position, originally presented in 1980 by Bas van Fraassen in his book The Scientific Image, crucially depends on the observable/unobservable dichotomy. Nevertheless, the question of what it means to observe has been faced in an unsatisfactory and inadequate manner by van Fraassen and this represents an important lacuna in his philosophical position. The aim of this work is to propose a characterization of the (...) act of observation able to give the necessary support to the ‘rough guide’ of ‘observable’ that can be found in the aforementioned book. Countering van Fraassen’s own statements, that observability is not a matter for philosophy, but for scientific inquiry only, we maintain that any attempt to deal with this subject by the philosophers is legitimate. We will show that van Fraassen ended up doing a philosophical analysis of observation himself, albeit in a fragmentary way. We believe that this question should be dealt with methodically, though, ‘following the rules’ of a ‘proper’ philosophical analysis, as we attempted to do in this work. We will propose a way of conceiving the act of observation, different from van Fraassen’s one, that can help not only to ground the distinction between observable and unobservable, upon which Constructive Empiricism rests, but to get this anti-realist position closer to scientific practice as well, which is one of its desiderata. Without neglecting the philosophical dimension of the issue, though. However, this proposal does not represent an ad hoc ‘solution’ for Constructive Empiricism, but a characterization aspiring to have a universal reach. (shrink)

This paper addresses a fundamental line of research in neuroscience: the identification of a putative neural processing core of the cerebral cortex, often claimed to be “canonical”. This “canonical” core would be shared by the entire cortex, and would explain why it is so powerful and diversified in tasks and functions, yet so uniform in architecture. The purpose of this paper is to analyze the search for canonical explanations over the past 40 years, discussing the theoretical frameworks informing this research. (...) It will highlight a bias that, in my opinion, has limited the success of this research project, that of overlooking the dimension of cortical development. The earliest explanation of the cerebral cortex as canonical was attempted by David Marr, deriving putative cortical circuits from general mathematical laws, loosely following a deductive-nomological account. Although Marr’s theory turned out to be incorrect, one of its merits was to have put the issue of cortical circuit development at the top of his agenda. This aspect has been largely neglected in much of the research on canonical models that has followed. Models proposed in the 1980s were conceived as mechanistic. They identified a small number of components that interacted as a basic circuit, with each component defined as a function. More recent models have been presented as idealized canonical computations, distinct from mechanistic explanations, due to the lack of identifiable cortical components. Currently, the entire enterprise of coming up with a single canonical explanation has been criticized as being misguided, and the premise of the uniformity of the cortex has been strongly challenged. This debate is analyzed here. The legacy of the canonical circuit concept is reflected in both positive and negative ways in recent large-scale brain projects, such as the Human Brain Project. One positive aspect is that these projects might achieve the aim of producing detailed simulations of cortical electrical activity, a negative one regards whether they will be able to find ways of simulating how circuits actually develop.

Sleep and dreaming are important daily phenomena that are receiving growing attention from both the scientific and the philosophical communities. The increasingly popular predictive brain framework within cognitive science aims to give a full account of all aspects of cognition. The aim of this paper is to critically assess the theoretical advantages of Predictive Processing (PP, as proposed by Clark 2013, Clark 2016; and Hohwy 2013) in defining sleep and dreaming. After a brief introduction, we overview the state of the (...) art at the intersection between dream research and PP (with particular reference to Hobson and Friston 2012; Hobson et al. 2014). In the following sections we focus on two theoretically promising aspects of the research program. First, we consider the explanations of phenomenal consciousness during sleep (i.e. dreaming) and how it arises from the neural work of the brain. PP provides a good picture of the peculiarity of dreaming but it can’t fully address the problem of how consciousness comes to be in the first place. We propose that Integrated Information Theory (IIT) (Oizumi et al. 2014; Tononi et al. 2016) is a good candidate for this role and we will show its advantages and points of contact with PP. After introducing IIT, we deal with the evolutionary function of sleeping and dreaming. We illustrate that PP fits with contemporary researches on the important adaptive function of sleep and we discuss why IIT can account for sleep mentation (i.e. dreaming) in evolutionary terms (Albantakis et al. 2014). In the final section, we discuss two future avenues for dream research that can fruitfully adopt the perspective offered by PP: (a) the role of bodily predictions in the constitution of the sleeping brain activity and the dreaming experience, and (b) the precise role of the difference stages of sleep (REM (Rapid eye movement), NREM (Non-rapid eye movement) in the constitution and refinement of the predictive machinery.

Interpretations of Kant’s account of the forms of “taking-to-be-true” (Fürwahrhalten) have generally focused on three such forms: opinion (Meinung), belief (Glaube), and knowledge (Wissen). A second distinction that has received comparatively less attention is that between conviction (Überzeugung) and persuasion (Überredung). Kant appears to use the distinction between the subjective and the objective sufficiency of a taking-to-be-true to characterize all of these forms. However, it is impossible to account for the differences between them by relying on this latter distinction alone. (...) In turn, this makes it difficult to fit all of these forms into a single classification of taking-to-be-true. In this chapter, I propose a new approach to conviction and persuasion that dissolves these problems. Conviction and persuasion are not single forms of taking-to-be-true with distinctive characteristics, yet it is not useful to treat them as “classes” of taking-to-be-true either. Rather, they are “operators” that determine whether a taking-to-be-true is apt or inapt, depending on whether it rests on a correct evaluation of the grounds we have. (shrink)

In an effort to produce new and more sustainable technologies, designers have turned to nature in search of inspiration and innovation. Biomimetic design (from the Greek bios, life, mimesis, imitation) is the conscious imitation of biological models to solve today's technical and ecological challenges. Nowadays numerous different approaches exist that take inspiration from nature as a model for design, such as biomimicry, biomimetics, bionics, permaculture, ecological engineering, etc. This variety of practices comes in turn with a wide range of different (...) promises, including sustainability, increased resilience, multi-functionality, and a lower degree of risk. How are we to make sense of this heterogeneous amalgam of existing practices and technologies, and of the numerous promises attached to them? We suggest that a typology of biomimetic approaches would provide a useful hermeneutic framework to understand the different tensions that pull this variegated landscape in different directions. This is achieved through a critical analysis of the literature in different fields of biomimetic design and the philosophy of biomimicry, in order to derive conceptual and normative assumptions concerning the meaning and value of the imitation of nature. These two dimensions are then intersected to derive an analytical grid composed of six different biomimetic types, which enable the classification of existing and possible biomimetic approaches, practices, and technologies according to their specific conceptual assumptions and guiding norms.

In this chapter, I investigate a problem for Kant’s claim that metaphysics can reach the status of science. The problem arises when one considers Kant’s account of the “architectonic unity” of metaphysics in the Architectonic of Pure Reason. Attaining architectonic unity is a condition for becoming a science for any body of cognitions that purports to be such. This is achieved when the cognitions belonging to a science are systematically organized according to the “idea of reason” which lies at the (...) basis of that science. However, Kant suggests that nobody can ever legitimately claim to have matched the idea of the philosopher, where this appears to imply that nobody can justifiably claim that she has fully grasped the idea of metaphysics. This generates a problem. I suggest that when Kant claims that the idea of the philosopher must remain an ideal or an archetype, he has a particular conception of philosophy in mind, that is, philosophy as a doctrine of wisdom. According to this understanding, philosophy must provide an example of how one can become virtuous. However, this is only a partial solution to our problem, for reasons that will be illustrated.

In this paper, I try to make sense of some puzzling claims that Peirce makes in the Cambridge conferences lectures. I identify four tasks that a successful interpretation of those claims must accomplish. First, we must provide a plausible reading of the “no belief in science” thesis. Second, we must provide a compelling interpretation of the “no science in vital matters” thesis. Third, we must explain Peirce’s distinction between two forms of holding for true. Fourth, we should be able to (...) solve the conflict with “The fixation of belief.” I start by analysing Christopher Hookway’s reading of Peirce’s claims because he clearly identifies these tasks and offers an interpretation with considerable merits. However, I identify a problem in Hookway’s reading, since he fails to account for a normative dimension of the “no science in vital matters” thesis. Finally, I sketch my attempt to accomplish these four tasks while also avoiding this latter problem. (shrink)

This chapter analyzes two short texts in which Peirce sketches out an anti-skeptical argument inspired by Kant’s refutation of idealism. The chapter will first consider why Peirce found Kant’s argument interesting and promising, given that it is often regarded as problematic and unsuccessful. It will then briefly reconstruct Kant’s refutation, highlighting its most problematic passages. Moreover, since Peirce’s own version of the argument relies on Kant’s views regarding the temporal structure of consciousness, the chapter will explain how Peirce tackles this (...) issue in “The Law of Mind.” Finally, the chapter considers Peirce’s own anti-skeptical argument and examines whether and how it can be seen as appropriating Kant’s strategy.

Famously, in the essay Inquiry Concerning the Distinctness of the Principles of Natural Theology and Morality (Prize Essay), Kant attempts to distance himself from the Wolffian model of philosophical inquiry. In this respect, Kant scholars have pointed out Kant’s claim that philosophy should not imitate the method of mathematics and his appeal to Newton’s “analytic method.” In this article, I argue that there is an aspect of Kant’s critique of the Wolffian model that has been neglected. Kant presents a powerful (...) attack of the idea that philosophy should proceed through the analysis of concepts and argues that we should give up the aim of arriving at “complete” concepts as one of its fundamental desiderata. Importantly, this attack of philosophy conceived as conceptual analysis is distinctive and original if one compares it with Kant’s critique of analysis in the Critique of Pure Reason, which rests on the idea that analysis is insufficient to ground substantial metaphysical truths. I also make an additional point: Scholars have debated whether the appeal to Newton’s analytic method involves a form of empiricism. I submit that this debate is ill-conceived because Kant uses a notion of “given concepts” that is indeterminate with respect to their a priori or a posteriori status. (shrink)

I respond to Karin de Boer, Thomas Land, and Claudio La Rocca’s comments on Kant’s Critique of Pure Reason and the Method of Metaphysics (CUP 2023). I first provide a quick outline of some of the main claims I make in the book. I then directly address their criticisms, which I group into three categories. The first group of comments raises doubts concerning my characterization of the central tasks of the critique of pure reason. The second targets the fact that (...) I downplay faculty analysis as an essential characteristic of the critique. The third has to do with my claim that the Critique of Pure Reason aims to show that metaphysics is capable of architectonic unity, where this unity is only achievable when we construe metaphysics according to the worldly concept of philosophy.

In Kant’s Critique of Pure Reason and the Method of Metaphysics (CUP 2023), I argue that the first Critique is not only a ‘propaedeutic’ to metaphysics, but actually already establishes parts of metaphysics. These parts belong to what Kant calls transcendental philosophy. Additionally, I also provide an account of Kant’s critique of dogmatism and Wolff as its main defender. In this paper, I take up Luigi Filieri’s and Davide Dalla Rosa’s invitation to further develop my characterization of transcendental philosophy and (...) I respond to Michael Walschots’s objections against my interpretation of Kant’s critique of Wolff’s dogmatism. (shrink)

Vera Zasulich’s shooting of Trepov, a governor of St Petersburg who had ordered the flogging of a political prisoner, in January 1878, catapulted her to international fame as a revolutionary heroine, a reputation that she put to good use by becoming one of the five ‘founding parents’ of Russian Marxism that created the ‘Group for the Emancipation of Labour’ in 1883. But her act of self-sacrifice also triggered, to her dismay, the institutionalisation of individual terrorist tactics in the Russian Populist (...) movement with the creation of the ‘People’s Will’ (Narodnaya Volya) Party in 1879. The organisation went into decline after the killing of Tsar Alexander II in 1881, and Populism itself was increasingly superseded by Marxism as the hegemonic force on the left with the rise of the Russian Social Democratic Labour Party (RSDLP). But individual terrorist tactics reappeared with the creation of the Socialist Revolutionary Party in 1902, prompting Zasulich to write an article for Die neue Zeit, the theoretical organ of German Social Democracy, in which she both condemned the Neo-Populist tendency as deleterious to the rising labour movement and supported the organisational plans for the RSDLP sponsored by the Iskra group, developed at length by Lenin in his book What Is to Be Done?, published in March 1902. This article provides the background to Vera Zasulich’s article ‘The Terrorist Tendency in Russia’ (December 1902), setting it against the history of the Russian revolutionary movement from 1878 to 1902.

This book discusses fundamental topics on contemporary Ockhamism. The collected essays show how contemporary Ockhamism can impact areas of research such as semantics, metaphysics and also the philosophy of science. In addition, the volume hosts one historian of Medieval philosophy who investigates the way in which William of Ockham “in flesh and bone” construed time and, more generally, future contingency. The essays explore the different meanings of this theory. They cover three main topics, in particular. The first examines the thesis (...) that sentences and propositions about the future have a definite truth value, without any ensuing commitment to determinism or fatalism. The second topic looks at the problem whether the branching-time model needs to countenance a privileged branch (the so-called Thin Red Line). Finally, the third topic considers the idea that there are so-called soft facts. These would be the subject matter of sentences and propositions verbally about the present or the past, but metaphysically about a later time, and which might change in the future. Overall, the book provides an updated and rigorous idea of the debate about Ockhamism. It gives readers a deeper understanding into this philosophical approach influenced by William of Ockham, characterized by the rejection of the Aristotelian idea that, in order to preserve the contingency of the future, future contingents must be deemed neither true nor false.

This article explores the Foucauldian analysis of the linkage between temporality and politics, addressing mainly two loci of Foucault’s production: the assessment of the post-WWII ordoliberal experience in The Birth of Biopoliticsand the Iran reportage for “Corriere Della Sera”. The article emphasizes the relevance of Foucault’s assessment of ordoliberal Germany for contemporary studies on neoliberalism and inscribes Foucault in a wider tradition of thought on the relevance of history and temporality for the comprehension of political dynamics. In TBoB, Foucault offered (...) a prescient analysis of neoliberal temporality and its de-politicizing effects. In his view, ordoliberal theorists and politicians sought to ground political legitimacy in the economy itself, giving birth to a political-economic “double circuit” which did away with history and made political consensus “permanent” and automatic. The connection between neoliberalism, the re-structuring of state sovereignty, and temporality will be highlighted. Furthermore, by analyzingthe almost-coeval Iranian reportages and the eulogy for Clavel, the article further investigates Fou-cault’s reflection on the link between temporality, politics,and subjectivation processes. If the anal-ysis of ordoliberal temporality in TBoB describes a linkage between de-temporalization and de-politicization, the reportages will be highlighted as a possible “pars construens” –as a way to reinstate the possibility of political action through the appeal to different ways to experience tem-porality. The article concludes that Foucault’s sparse comments on temporality can be read as an attempt, albeit not fully developed, not only to envision the de-politicizing effects of marketization but also to envisage new, re-politicizing modes of experiencing temporality and history.

Articolo divulgativo pubblicato su L'Indiscreto il 17 maggio 2024. Si tratta del primo di una serie di articoli che verranno raccolti come opera di divulgazione sulla filosofia analitica. Ripercorro la storia del divario analitico-continentale. Si possono individuare due principali forze dietro la filosofia continentale: la prima è quella di Heidegger (manifesta nella fenomenologia, nell'ermeneutica e nell'esistenzialismo), la seconda è quella di Marx (manifesta nella teoria critica e nel poststrutturalismo). Si individuano quindi quattro distinzioni tipiche tra la tradizione continentale e quella (...) analitica; si individuano però anche loro continue eccezioni. Inevitabilmente, si conclude che la distinzione è debolmente fondata. (shrink)

Articolo divulgativo pubblicato in Club Theologicum il 22 settembre 2023. Si tratta di una risposta a diversi articoli del noto teologo Giovanni Cavalcoli, OP. Cavalcoli offre una semplice argomentazione a favore dell'idea che l'esistenza di vita extraterrestre sia incoerente con la dottrina della Chiesa Cattolica.

Articolo divulgativo pubblicato nella rivista l'Indiscreto il 1 settembre 2021. Riccardo Manzotti è uno dei più originali filosofi della mente in Italia.

Articolo divulgativo pubblicato su L'Indiscreto il 21 dicembre 2022. Immaginiamo che i diversi numeri sull'asse delle ascisse rappresentino diverse domande alle quali posso rispondere.

Articolo divulgativo pubblicato su L'Indiscreto il 6 ottobre 2021. Il ragionamento dello scienziato e quello del mistico paiono essere agli antipodi. Seguendo un noto paragone di Badcock, lo scienziato tende a ipomentalizzare (interpreta come un meccanismo anche ciò che ha esprienze soggettive), il mistico a ipermentalizzare (assegna una volontà anche a ciò che non ha una mente). Eppure, in alcuni personaggi famosi, questi due diversi modi di pensare si fondono, rivelando una possibile unità tra i due modi di vedere il (...) mondo. Badcock immagina che Newton tendesse prima a ipermentalizzare (da cui la grande creatività) e poi a ipomentalizzare (per riportare i sogni entro i limiti della razionalità). Io propongo l'ipotesi che certi scienziati-mistici come Swedenborg attuassero un processo opposto, prima ipomentalizzando, e poi ipermentalizzando. (shrink)

Bozza di un articolo mai pubblicato. Originariamente pensato per la rivista Immoderati, non è più stato pubblicato a causa del passaggio della rivista al gruppo Liberi Oltre le Illusioni, oltre che alla cessazione della polemica che aveva motivato la stesura dell'articolo. Nella prima parte, analizzo il ruolo dell'omosessualità nella Lettera di Giuda, nel Levitico (per la quale si prevede la pena capitale) e nella Lettera ai Romani. Nella seconda, analizzo i giudizi dei Padri della Chiesa e alcune razionalizzazioni filosofiche della (...) condanna dell'omosessualità. Concludo che il canone Biblico di per sé non contiene alcuna condanna esplicita dell'omosessualità com'è oggi intesa, mentre tali condanne sono effettivamente presenti nella tradizione di pensiero recente. Ciò lascia comunque uno spazio di manovra che può consentire ai fedeli omosessuali di vivere con serenità la propria condizione nella Chiesa. (shrink)

Articolo divulgativo pubblicato su L'Indiscreto il 13 aprile 2022. Le opere d'arte sono analizzabili semioticamente: sono qualcosa che sta per qualcos'altro, oggetti che comunicano del significato. Analizzando le loro proprietà, concludo che le opere d'arte, per definizione, sono a metà via tra le icone e i simboli, e sono caratterizzate da un doppio rimando: l'oggetto artistico rimanda ad una qualche entità, che a sua volta viene reinterpreata e usata per comunicare qualcosa di universale. Si discute quindi l'aspetto cognitivo dell'opera d'arte: (...) posto davanti all'opera, il fruitore accede a reti di concetti che costituiscono la sua esperienza estetica. Poiché quali reti di concetti il fruitore esperirà dipende essenzialmente dalle caratteristiche proprie del fruitore stesso, ne consegue che la critica dovrebbe concentrarsi, non sulle caratteristiche delle opere, ma sui modi in cui tali caratteristiche possono interagire con diverse tipologie di fruitori.

Nella seconda parte affronto il problema del destino escatologico degli animali: le categorie di paradiso e inferno non risultano a essi applicabili in quanto non possono avere un rapporto diretto con Dio, ma possono avere un rapporto mediato (...) vedendo Cristo nell'uomo. Nella terza parte mi chiedo se, su base biblica, sia legittimo cibarsi di animali: concludo che lo è, ma solo momentaneamente, nello stato di cose presenti, e parimenti è legittima invece una dieta vegetariana.

Nella quinta parte presento la dottrina degli uffici angelici e demoniaci di Gregorio Magno, e spiego come tali uffici possano essere ricoperti anche da animali. (shrink)

Nel 2020, al fine di chiarirmi le idee sulle mie stesse posizioni filosofiche, ho iniziato a scrivere un libro che esponesse e valutasse le maggiori argomentazioni connesse a diverse questioni filosofiche. Lo condivido come bozza in quanto non intendo più modificarlo, e i suoi capitoli stanno venendo rielaborati e pubblicati in parte come articoli divulgativi, in parte come articoli scientifici. Il primo capitolo presenta varie scuole filosofiche e si concentra sulla tradizione analitica. Il secondo presenta il settore della teoria della (...) verità. Il terzo, la teoria della giustificazione. Il quarto, l'etica normativa. Il quinto, la metaetica. Il sesto, la filosofia dell'identità e dello spaziotempo. Il settimo, la filosofia del libro arbitrio. L'ottavo, la filosofia della matematica. Il nono, la filosofia della mente. I capitoli 1, 2, 3, 4 e 5 sono essenzialmente completi, pur mantenendo molte ingenuità giovanili (la loro riscrittura per la pubblicazione ha infatti necessitato molte specificazioni). I capitoli 6, 7 e 8 pure sono essenzialmente completi, ma mancano della bibliografia per le "letture consigliate". Il nono capitolo, invece, è rimasto come semplici appunti e richiederebbe una riscrittura profonda. Cose buone che si trovano in questo testo: quelle che ritengo essere le più semplici (ma rigorose) introduzioni ai teoremi di incompletezza di Goedel e ai paradossi EPR. (shrink)

In Chapter 8 of Kant’s Critique of Pure Reason and the Method of Metaphysics, one of Gabriele Gava’s aims is to argue that Kant’s critique of Wolff’s dogmatic method has two levels: one directed against Wolff’s metaphilosophical views and one attacking his actual procedures of argument. After providing a brief summary of the main claims Gava makes in Chapter 8 of his book, in this paper I argue two things. First, I argue against Gava’s claim that the (...) two forms of dogmatism he distinguishes between are incompatible. Second, I suggest, contrary to Gava, that Kant’s critique of these two forms of dogmatism both operate on the metaphilosophical level in the sense that they both target the dogmatist’s beliefs or theory about the method they take themselves to be following.

Gabriele Gava's new monograph makes sense of Kant's obscure claim that the Critique of Pure Reason is a "doctrine of method" for the science of metaphysics. Gava does this by offering a reading of the whole Critique as aiming to show that metaphysics can become an "architectonic" science. The book shows impressive range; it covers diverse topics throughout the Aesthetic, Analytic, Dialectic, and Method, brings out appealing parallels between them, and relates them to the task of exhibiting metaphysic's (...) architectonic unity. But, I argue, it stops short of a full explanation of how the Critique is meant to outline or anticipate the whole of metaphysics in advance of actually completing that science. (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.

Abstract: This paper traces a Kantian and pragmatist line of thinking that connects the ideas of conceptual content, object cognition, and modal constraints in the form of counterfactual sustaining causal laws. It is an idea that extends from Kant’s Critique of Pure Reason through C. I. Lewis’s Mind and the World-Order to the Kantian naturalism of Wilfrid Sellars and the analytic pragmatism of Robert Brandom. Kant put forward what I characterize as a modal conception of objectivity, which he developed as (...) an extended argument stretching from the transcendental deduction through the analogies of experience to the regulative maxims of reason and reflective judgment. In related ways in Lewis and Sellars, the very idea of an object of knowledge (and of intentionality more generally) is connected with a certain lawfulness or modal constraint the necessary representation of which, they argue, is an achievement of conceptualization. While Sellars agreed with the spirit of Lewis’s famous pragmatic conception of the a priori, Sellars’s conception of meaning and conceptual content differed in crucial ways with important consequences for this issue. I argue furthermore that a certain phenomenalist temptation threatens to spoil this insight both among some of Kant’s interpreters and in Lewis’s thought. Finally, I point out that Brandom’s “Kant-Sellars thesis” provides new support for this line of thought. Although questions concerning idealism continue to raise controversies for neo-Kantians and pragmatists, the line of thought itself represents a distinctive and still promising approach to questions concerning intentionality and conceptual content.
