A hipótese do fechamento cognitivo afirma que, devido à organização cognitiva da mente humana, a classe de conceitos acessíveis é limitada e que por consequência deste fato algumas crenças e hipóteses sobre aspectos da realidade terão de estar fora do alcance teórico humano e serão inacessíveis. Neste artigo, analisamos uma interpretação de David Hume, segundo a qual o autor afirmou conjuntamente a tese realista de que poderes causais em objetos existem e a tese cética de que não temos um acesso (...) à natureza destes poderes, sensório ou conceitual. Para tal, contextualizamos o surgimento desta interpretação como uma alternativa aos fracassos da interpretação tradicional de Hume e analisamos individualmente as abordagens realizadas por seus principais defensores. Assim feito, buscamos explorar à luz desta interpretação realista cética a possibilidade da tese de Hume ter antecipado a tese contemporânea do fechamento cognitivo. Acredita-se que essa hipótese implica um desafio tanto a interpretações que enxergam o filósofo como um precedente da filosofia analítica do positivismo lógico quanto a acusações de que fechamento cognitivo é uma tese pós-moderna.

The essay revisits the puzzle of the ‘passage’ of time in relation to EPR-type measurements and asks what philosophical consequences can be drawn from them. Some argue that the lack of invariance of temporal order in the measurement of a space-like related EPR pair, under relativistic motion, casts serious doubts on the ‘reality’ of the lapse of time. Others argue thatcertain features of quantum mechanics establisha tensed theory of time – understood here as Possibilism or the growing block universe. The (...) paper analyzes the employment of frame-invariant entropic clocks in a relativistic setting and argues that tenselessness does not imply timelessness. But this conclusion does not support a tensed theory of time, which requires a preferred foliation. It is argued that the only reliable inference from the EPR example and the use of entropic clocks is an inference not just to a Leibnizian order of the succession of events but a frame-invariant order according to some selected clocks.

ABSTRACT ABSTRACT: In metaphysics, the adjective ‘Humean’ is used to describe positions that deny the existence of any necessary connection or causal influence in concrete reality. This usage has been significantly reinforced by David Lewis’s employment of ‘Humean’ in the phrase ‘Humean supervenience’. It is, however, not at all clear that this usage is appropriate. Lewis himself raised a doubt about it.

This article investigates the relationship between Hume’s causal philosophy and Newton ’s philosophy of nature. I claim that Newton ’s experimentalist methodology in gravity research is an important background for understanding Hume’s conception of causality: Hume sees the relation of cause and effect as not being founded on a priori reasoning, similar to the way that Newton criticized non - empirical hypotheses about the properties of gravity. However, according to Hume’s criteria of causal inference, the law of universal gravitation is (...) not a complete causal law, since it does not include a reference either to contiguity or to temporal priority. It is still argued that because of the empirical success of Newton ’s theory—the law is a statement of an exceptionless repetition—Hume gives his support to it in interpreting gravity force instrumentally as if it bore a causal relation to motion.

The main aim of this paper is to explore why it is so important for Hume to defi ne ‘cause’ as he does. This will shed light on the signifi cance of the natural/philosophical relation (hereafter NPR) distinction in the Treatise. Hume's use of the NPR distinction allows him to dismiss on general grounds conceptions of causation at odds with his own. In particular, it allows him to avoid having to engage in detailed re-interpretation of potentially confl icting theories formulated (...) by natural philosophers. Moreover, it provides an instance of the normative nature of Hume's “science of man.” The paper argues that the NPR distinction - in conjunction with the so-called copy principle - is meant to undercut appeals to the authority of theories not founded on Hume's “principles.” In order to illustrate its claims about Hume, this essay explores some aspects of Newton's natural philosophy. Finally, this paper resolves a long-standing interpretive problem: how to reconcile Hume's two “defi nitions” of causation in the Treatise. (shrink)

How can Hume account for the meaning of causal claims? The causal realist, I argue, is, on Hume's view, saying something nonsensical. I argue that both realist and agnostic interpretations of Hume are inconsistent with his view of language and intentionality. But what then accounts for this illusion of meaning? And even when we use causal terms in accordance with Hume’s definitions, we seem merely to be making disguised self-reports. I argue that Hume’s view is not as implausible as it (...) sounds by exploring his conception of language. (shrink)

The ‘New Hume’ interpretation, which sees Hume as a realist about ‘thick’ Causal powers, has been largely motivated by his evident commitment to causal language and causal science. In this, however, it is fundamentally misguided, failing to recognise how Hume exploits his anti-realist conclusions about (upper-case) Causation precisely to support (lower-case) causal science. When critically examined, none of the standard New Humean arguments — familiar from the work of Wright, Craig, Strawson, Buckle, Kail, and others — retains any significant force (...) against the plain evidence of Hume's; texts. But the most devastating objection comes from Hume's own applications of his analysis of causation, to the questions of ‘the immateriality of the soul’ and ‘liberty and necessity’. These show that the New Hume interpretation has misunderstood the entire purpose of his ‘Chief Argument’, and presented him as advocating some of the very positions he is arguing most strongly against.

Hume frequently states that we are ignorant of genuine power. There is a well-known internal difficulty concerning this claim concerning ignorance. According to Hume, we do not have an impression-based idea of genuine power; on the other hand, every noun needs a corresponding idea to be meaningful. Is his claim concerning ignorance, which makes use of the noun ‘power’, meaningless in light of his own criterion of meaningfulness? I focus on two exegetical approaches to this difficulty proposed in the literature (...) of the ‘New Hume Debate’: 1) we may read Hume's own positive definitions of power back into his claim of ignorance to ensure the meaningfulness of ‘power’; and 2) ‘power’ may correspond to a relative idea of genuine power and derive its meaning from this relative idea. I argue against both of these solutions and offer my own solution that is quite close to the text. However, adopting my proposal demands a price: a considerable part of Hume's argumentative undert..

Traditionally one main emphasis of the quantum mechanical measurement theory is on the question how the pure state of the compound system 'measured system + measuring apparatus' is transformed into the 'mixture' of all possible results of that measurement, weighted with their probability: the so-called “disappearance of the interference terms”. It is argued in this note that in reality there is no such transformation, so that there is no need to account for such a transformation theoretically. _German_ Gewöhnlich liegt ein (...) Hauptgewicht der quantenmechanischen Messtheorie auf der Frage des Übergangs vom,reinen Fall' des Gesamtsystems,gemessenes System + Messgerät' in das,Gemenge' aus allen möglichen Messergebnissen, gewichtet mit ihren Wahrscheinlichkeiten: Das sog.,,Verschwinden der Interferenzterme“. In dieser Notiz wird die Meinung vertreten, dass es einen solchen Übergang faktisch nicht gibt, so dass es nicht notwendig ist, eine theoretische Erklärung für den Übergang zu geben. (shrink)

Hume is known for his claim that our idea of causation is nothing beyond constant conjunction, and that our idea of necessary connection is nothing beyond a felt determination of the mind. In short, Hume endorses a "thin" conception of causation and necessary connection. In recent years, however, a sizeable number of philosophers have come to view Hume as someone who believes in the existence of thick causal connections - that is, causal connections that allow one to infer a priori (...) the effect from the cause, and vice versa. Hume doesn't wish to deny such connections, said philosopher's claim, he only seeks to demonstrate that we can't know anything about the nature of the thick causal connections that make up the natural world. In this dissertation, I defend the old or traditional interpretation of Hume on causation. I draw attention to the important but neglected role of clear and distinct perception in Hume's thought, arguing that for Hume our impressions are clear and distinct perceptions, whereas our ideas are faint and obscure. Accordingly, Hume's copy principle - the thesis that our ideas are copies of our impressions - is Hume's way of rendering our naturally obscure and confused ideas distinct. One need only discern the impression from which said ideas are copied. In this way, I show that Hume's opinion concerning our idea of thick causation is that it's an obscure and confused idea, and that the only clear and distinct idea we can have of causation is thin causation. Furthermore, since meaning for Hume is a matter of a word's being associated with an idea, Hume thinks that an expression such as "thick causation" is meaningless or confused. In one sense, then, Hume is a positivist, and as such doesn't believe in thick causal connections. (shrink)

The subject of this essay-based dissertation is Hume’s natural philosophy. The dissertation consists of four separate essays and an introduction. These essays do not only treat Hume’s views on the topic of natural philosophy, but his views are placed into a broader context of history of philosophy and science, physics in particular. The introductory section outlines the historical context, shows how the individual essays are connected, expounds what kind of research methodology has been used, and encapsulates the research contributions of (...) the essays. The first essay treats Newton’s experimentalist methodology in gravity research and its relation to Hume’s causal philosophy. It is argued that Hume does not see the relation of cause and effect as being founded on a priori reasoning, similar to the way in which Newton criticized non-empirical hypotheses about the causal properties of gravity. Contrary to Hume’s rules of causation, the universal law does not include a reference either to contiguity or succession, but Hume accepts it in interpreting the force and the law of gravity instrumentally. The second article considers Newtonian and non-Newtonian elements in Hume more broadly. He is sympathetic to many prominently Newtonian themes in natural philosophy, such as experimentalism, critique of hypotheses, inductive proof, and the critique of Leibnizian principles of sufficient reason and intelligibility. However, Hume is not a Newtonian philosopher in many respects: his conceptions regarding space and time, the vacuum, the specifics of causation, the status of mechanism, and the reality of forces differ markedly from Newton’s related conceptions. The third article focuses on Hume’s Fork and the proper epistemic status of propositions of mixed mathematics. It is shown that the epistemic status of propositions of mixed mathematics, such as those concerning laws of nature, is that of matters of fact. The reason for this is that the propositions of mixed mathematics are dependent on the Uniformity Principle. The fourth article analyzes Einstein’s acknowledgement of Hume regarding special relativity. The views of the scientist and the philosopher are juxtaposed, and it is argued that there are two common points to be found in their writings, namely an empiricist theory of ideas and concepts and a relationist ontology regarding space and time.

This thesis argues that Kant is able to maintain the distinctiveness of his position in opposition to Hume's naturalism (contrary to the arguments of R. A. Mall and L. W. Beck) without invoking premises which are question begging with regard to Hume's scepticism. The argument of Kant's Transcendental Deduction of the Categories, as presented in the second edition of the Critique of Pure Reason, is considered in relation to the two sets of criticism that have been levelled at it from (...) its publication up to the present day, both of which aim to demonstrate that synthetic a priori judgements are subjectively necessary but without objective validity. The first set of criticisms involves problems raised with regard to the status of transcendental arguments. The difficulties identified here (by B. Stroud, M. S. Gram, and others) are that the Deduction can either, at best, show that it is necessary for experience to be regarded in a certain way without demonstrating anything as to the nature of experience as such, or the argument is circular in that it begins by making assumptions regarding the nature of our experience. Alternatively, if the Deduction is taken to establish the objective nature of concepts via an analysis of the conditions under which it is possible for us to have some knowledge of ourselves, then incoherence is said to arise because this requires either an implausible reflective theory of consciousness (according to D. Henrich) or that we have knowledge of the subject-in-itself (as held by J. G. Fichte and other contemporaries of Kant). Through a consideration of both the historical and contemporary manifestations of these criticisms, the thesis advances an interpretation of the Deduction, with special attention paid to the role and nature of the subject, which does not fall prey to the alleged incoherence. As such, the thesis defends both the distinctiveness and legitimacy of transcendental philosophy. (shrink)

Modern Hume scholarship is still divided into two major camps when it comes to the issue of causation. There are those scholars who interpret Hume as a causal anti-realist, and there are those who interpret him as a causal realist. In my paper, I argue that there is an overwhelming amount of evidence – especially textual evidence – that should lead us to read Hume as being a causal anti-realist. That is to say, one who believes that cause and effect (...) relations are felt and known in the mind of the perceiver alone; not in objects themselves. I then attempt to settle, at least partially, the ‘two definitions of cause dispute’ that was brought about by Hume’s giving us not one, but two non-equivalent and non-substitutable definitions of the cause and effect relation.
