O presente ensaio aborda a presença de Nietzsche nos Cadernos negros de Heidegger com o intuito de esclarecer e analisar o papel filosófico que Nietzsche aí desempenha. A partir de ferramentas hermenêuticas básicas para a leitura e interpretação do conjunto dos textos que compõem o conjunto chamado Cadernos negros, composto de textos enigmáticos e únicos em relação ao corpus heideggeriano, a figura de Nietzsche aparece não apenas como um centro de referência privilegiado para o pensamento heideggeriano da década de 1930-40, (...) mas também, e principalmente, como o impulso fundamental da profunda reformulação de suas coordenadas principais.

El presente ensayo quiere reflexionar sobre la experiencia y los obstáculos –que a veces llegan a ser verdaderas contraindicaciones– de un doctorado en filosofía a partir del desafío personal que representa la decisión de tomar este camino académico y profesional, hasta la conclusión de la tesis y la defensa final del trabajo. Las consideraciones que siguen se enfocan en algunos elementos típicos que el estudiante enfrenta durante su aventura personal y universitaria de estudios doctorales, como la relación con el director (...) de tesis, el desarrollo de la investigación, la preocupación por la financiación, etc. El campo de mediación y/o batalla entre la filosofía como trabajo y como forma de vida es la soledad del doctorando.

O artigo tem por objetivo investigar a particular relação que se estabelece entre a temática do início da filosofia – que é de extrema importância para toda a “escola fenomenológica de Freiburg” – e a concepção da essência da filosofia tal como desenvolvida especificamente no pensamento de Martin Heidegger e Eugen Fink. A partir da reinterpretação e radicalização operadas em relação à abordagem estabelecida pela fenomenologia husserliana, mostraremos como a figura de Husserl se impõe tanto como pano de fundo quanto (...) como alvo polêmico das reflexões de Heidegger e Fink. Assim, se o primeiro desenvolve uma concepção da filosofia como práxis radical de um “outro” pensamento, que procede por tentativas e experimentações, o segundo transforma a fenomenologia husserliana no sentido de uma filosofia da liberdade.

Estudo introdutório de apresentação, seguido de tradução, da palestra “Fenomenologia e antropologia”, ministradas por Edmund Husserl nas sedes da Kantgesellschaft de Frankfurt, Berlim e Halle em 1931, na qual avalia criticamente, a partir dos pressupostos transcendentais da fenomenologia, a tendência da filosofia alemã dos anos 20 do século passado para uma antropologia filosófica.

O presente artigo apresenta um estudo detalhado sobre a dimensão performativa implícita na redução fenomenológica a partir de uma análise das obras de Edmund Husserl e da sua reinterpretação nas contribuições de Eugen Fink. Atribuindo à função do espectador transcendental a estrutura de janela, estrutura esta previamente desenvolvida nas pesquisas sobre os atos das presentificações em geral e sobre a consciência de imagem em particular, Fink consegue demonstrar a medialidade característica da redução, verdadeiro centro operativo da fenomenologia. Essa função medial (...) — situada, como uma janela, entre o âmbito mundano e a esfera transcendental — será um elemento fundamental tanto para o desenvolvimento da fenomenologia constitutiva de Husserl e suas análises sobre a história transcendental, quanto para a teoria transcendental do método e sua tematização pelo pensamento fenomenológico in fieri, bem como para a declinação meôntica da fenomenologia proposta por Fink. Neste sentido, a operação da redução será radicalizada numa performance que pretende “fissurar” a “superfície da vida transcendental”, criando aí uma abertura ao transcendental. A partir deste topos medial, o espectador transcendental se torna, portanto, uma espécie de panopticum “não envolvido” e “imparcial” do jogo da constituição, o qual ele pode enxergar através da janela aberta pela redução entre o âmbito natural e o transcendental como um imenso espetáculo. O espetáculo da “ontogênese” transcendental — anteriormente escondida uma latência anônima, sepultada na profundidade de um esquecimento “antigo como o mundo” — apresenta-se entre a subjetividade constituinte transcendental e seu produto final: a finitude, a correlação experiencial constituída entre ser humano e mundo. Finalmente, retomando as sugestões implicadas no fenômeno da imagem, as conclusões traçam um paralelismo com os famosos Cortes de Luciano Fontana, obras de arte performativa que, substituindo a represented spatiality por uma acted spatiality, rompem com o espaço “natural” e tradicional da imagem para adentrar, através da criação de uma cesura, de um corte na superfície da imagem, o infinito.

Formal topology aims at developing general topology in intuitionistic and predicative mathematics. Many classical results of general topology have been already brought into the realm of constructive mathematics by using formal topology and also new light on basic topological notions was gained with this approach which allows distinction which are not expressible in classical topology. Here we give a systematic exposition of one of the main tools in formal topology: inductive generation. In fact, many formal topologies can be presented in (...) a predicative way by an inductive generation and thus their properties can be proved inductively. We show however that some natural complete Heyting algebra cannot be inductively defined. (shrink)

Martin-Löf Type Theory is both an important and practical formalization and a focus for a charismatic view of the foundations of mathematics. Per Martin-Löf's work has been of huge significance in the fields of logic and the foundations of mathematics, and has important applications in areas such as computing science and linguistics. This volume celebrates the twenty-fifth anniversary of the birth of the subject, and is an invaluable record both of areas of currentactivity and of the early development of the (...) subject. Also published for the first time is one of Per Martin-Löf's earliest papers. (shrink)

This volume draws together contributions from researchers whose work builds on the theory developed by Martin-Lof over the last twenty-five years.

Although the fifteenth century showed some signs of traditionalism and disintegration, there were also highly original new solutions to long-debated problemsin scholastic and humanistic discourse. As for the relation between faith and reason, Nicholas of Cusa, Giovanni Pico della Mirandola, and Savonarola foundnew ways to integrate these poles, around which theological and philosophical thought was organized. As a common pattern, one can discern a striving beyond the established systems of humanism and scholasticism, mingling elements of both traditions with those (...) from the movements of spiritual reform in the later Middle Ages. This “striving beyond” was possible due to a performative turn in the fifteenth century: thinking and acting were connected by the narrator or the author in a manner that produced theoretical concepts and acts in social reality by writing, thinking, and actively developing the self.

This article explores the presence and function of texts by two spokesmen of the Franciscan Observance sub vicaris, namely Giovanni of Capestrano and Jan Brugman, within a religious miscellany most probably used – if not composed – by the Brothers of the Common Life in the house of Lüchtenhof, founded in 1440 in the neighbourhood of Hildesheim, Lower Saxony. The miscellany attests to the influence of these two prominent preachers beyond their religious order and beyond the geographic areas in (...) which they had been active, thus showing the exchange and interconnection between different branches of the so-called Observant movement.The article first describes the...

Many philosophers have been attracted to the idea of using the logical form of a true sentence as a guide to the metaphysical grounds of the fact stated by that sentence. This paper looks at a particular instance of that idea: the widely accepted principle that disjunctions are grounded in their true disjuncts. I will argue that an unrestricted version of this principle has several problematic consequences and that it’s not obvious how the principle might be restricted in order to (...) avoid them. My suggestion is that, instead of trying to restrict the principle, we should distinguish between metaphysical and conceptual grounds and take the principle to apply exclusively to the latter. This suggestion, if correct, carries over to other prominent attempts at using logical form as a guide to ground. (shrink)

There are two intuitions about time. The first is that there's something special about the present that objectively differentiates it from the past and the future. Call this intuition Specialness. The second is that the time at which we happen to live is just one among many other times, all of which are ‘on a par’ when it comes to their forming part of reality. Call this other intuition Egalitarianism. Tradition has it that the so-called ‘A-theories of time’ fare well (...) at addressing the first intuition, but rather badly when it comes to the second. The goal of this article is to offer advice to A-theorists about how to reconcile their view with Egalitarianism. (shrink)

Humanity’s self-ordained mandate to subdue and dominate nature is part of the cognitive foundation of the modern world—a perspective that remains deeply ingrained in science and technology. Marine biology has not been immune to this anthropocentric bias. But this needs to change, and the gaps between basic scientific disciplines and the global conservation imperatives of our time need to be bridged. In the face of a looming ecological and climate crisis, marine biologists must upgrade their values and professional standards and (...) help foster the radical transformation needed to avert a climate and ecological breakdown. To prevent some of the damage, they must cross the imaginary line that separates science from science-based activism and consciously pursue the health and durability of human and natural communities. To this end, they can (1) develop compelling narratives that engage human society, with emphasis on care for the wild living world; (2) move beyond marine conservation on paper and avoid self-serving complaisance; (3) advocate constructive changes in market and human behaviour, not only by documenting damage but also by clarifying how the extraction, production and consumption system can be steered away from practices that harm nature; (4) push for systemic change in politics through individual and collective efforts, supporting environmental activism and those who demand biosphere-saving policies; and (5) endorse a more ecocentric and holistic world vision, relinquishing contempt for spiritual wisdom and liaising with (or at least not dismissing) spiritual traditions that encourage equality, self-restraint and environmental sustainability.

Solving the meta-problem of consciousness requires, among other things, explaining why we are so reluctant to endorse various forms of illusionism about the phenomenal. I will try to tackle this task in two steps. The first consists in clarifying how the concept of consciousness precludes the possibility of any distinction between 'appearance' and 'reality'. The second consists in spelling out our reasons for recognizing the existence of something that satisfies that concept.

This paper addresses theoretical challenges, still relevant today, that arose in the first decades of the twentieth century related to the concept of the organism. During this period, new insights into the plasticity and robustness of organisms as well as their complex interactions fueled calls, especially in the UK and in the German-speaking world, for grounding biological theory on the concept of the organism. This new organism-centered biology understood organisms as the most important explanatory and methodological unit in biological investigations. (...) At least three theoretical strands can be distinguished in this movement: Organicism, dialectical materialism, and holistic biology. This paper shows that a major challenge of OCB was to describe the individual organism as a causally autonomous and discrete unit with consistent boundaries and, at the same time, as inextricably interwoven with its environment. In other words, OCB had to conciliate individualistic with anti-individualistic perspectives. This challenge was addressed by developing a concept of life that included functionalist and metabolic elements, as well as biochemical and physical ones. It allowed for specifying organisms as life forms that actively delimit themselves from the environment. Finally, this paper shows that the recent return to the concept of the organism, especially in the so-called “Extended Evolutionary Synthesis,” is challenged by similar anti-individualistic tendencies. However, in contrast to its early-twentieth-century forerunner, today’s organism-centered approaches have not yet offered a solution to this problem. (shrink)

This paper provides an analysis of the intrinsic/extrinsic distinction, as applied both to properties and to relations. In contrast to other accounts, the approach taken here locates the source of a property’s intrinsicality or extrinsicality in the manner in which that property is ‘logically constituted’, and thus – plausibly – in its nature or essence, rather than in e.g. its modal profile. Another respect in which the present proposal differs from many extant analyses lies in the fact that it does (...) not seek to analyse the ‘global’ distinction between intrinsic and extrinsic properties on the basis of the ‘local’ distinction between having a property intrinsically and having it extrinsically. Instead, the latter distinction is explicated on the basis of the former. (shrink)

In recent years, biologists and philosophers of science have argued that evolutionary theory should incorporate more seriously the idea of ‘reciprocal causation.’ This notion refers to feedback loops whereby organisms change their experiences of the environment or alter the physical properties of their surroundings. In these loops, in particular niche constructing activities are central, since they may alter selection pressures acting on organisms, and thus affect their evolutionary trajectories. This paper discusses long-standing problems that emerge when studying such reciprocal causal (...) processes between organisms and environments. By comparing past approaches to reciprocal causation from the early twentieth century with contemporary ones in niche construction theory, we identify two central reoccurring problems: All of these approaches have not been able to provide a conceptual framework that allows maintaining meaningful boundaries between organisms and environments, instead of merging the two, and integrating experiential and physical kinds of reciprocal causation. By building on case studies of niche construction research, we provide a model that is able to solve these two problems. It allows distinguishing between mutually interacting organisms and environments in complex scenarios, as well as integrating various forms of experiential and physical niche construction. (shrink)

Assuming a radical stance on embodied cognition, according to which the information ac- quired through basic cognitive processes is not contentful (Hutto and Myin, 2013), and as- suming that perception is a source of rationally grounded knowledge (Pritchard, 2012), a pluralistic account of perceptual knowledge is developed. The paper explains: (i) how the varieties of perceptual knowledge fall under the same broader category; (ii) how they are subject to the same kind of normative constraints; (iii) why there could not be (...) a conflict between the different varieties of perceptual knowledge; and (iv) why the traditional episte- mological inquiry is inclined to overestimate the role of propositional perceptual knowledge.

Insight problem solving is thought to underpin creative thought as it incorporates both divergent (generating multiple ideas and solutions) and convergent (arriving at the optimal solution) thinking approaches. The current literature on schizotypy and creativity is mixed and requires clarification. An alternate approach was employed by designing an exploratory web-based study using only correlates of schizotypal traits (paranoia, dissociation, cognitive failures, fantasy proneness, and unusual sleep experiences) and examining which (if any) predicted optimal performance on an insight problem-solving task. One (...) hundred and twenty-one participants were recruited online from the general population and completed the number reduction task. The discovery of the hidden rule (HR) was used as a measure of insight. Multivariate logistic regression analyses highlighted persecutory ideation to best predict the discovery of the HR (OR = 1.05; 95% CI 1.01–1.10, p = 0.017), with a one-point increase in persecutory ideas corresponding to the participant being 5% more likely to discover the HR. This result suggests that persecutory ideation, above other schizotypy correlates, may be involved in insight problem solving. (shrink)

In the paper, after clarifying terms such as ‘identity’, ‘self’ and ‘personhood’, I propose an empirical account of identity based on the notion of “whole phenotype”. This move allows one to claim the persistence of the individuals before and after their being affected by dementia. Furthermore, I show how this account permits us to address significant questions related to demented individuals’ loss of the capacity of moral decisions.
