Hume: Scientific Method

We may distinguish two interpretations of the relation between Newton’s natural philosophy and Hume’s science of human nature. The first interpretation can be called ‘traditional,’ the second ‘critical.’ This article will not side with either readings of Hume’s Newtonianism (or with some middle positions). Instead, essential points of confluence and divergence will be discussed.

Gözlemlenenlerden gözlemlen(e)meyenlere diğer bir deyişle genel yasalara ulaşma imkânı veren çıkarım yöntemi olarak tümevarımsal ya da endüktif akıl yürütmenin rasyonel olarak temellendirilmesinin imkanına yönelik soruşturma tarih içerisinde tümevarım sorunu ya da endüksiyon problemi olarak tezahür etmiştir. Bu sorunun temel argümanı tarihsel okumalara baktığımızda İskoç ampirist filozof David Hume tarafından öne sürülmüştür. Hume, tümevarımsal çıkarımlar temelinde, gözlenmeyen meseleler hakkındaki inançlarımıza hangi gerekçelerle ulaştığımızı soruşturmaktadır. Hume soruşturmasının sonucunda gözlemlenenden gözlemlen(e)meyen durumlara ilişkin yapılan olgu meseleleri ile ilgili bütün tümevarımsal akıl yürütmelerin dolaylı ya (...) da dolaysız olarak nedensellik ilişkisine ve bu ilişkinin temelinde yer alan doğanın düzenliliği ilkesi ya da “gelecek her zaman geçmişe benzer” önermesine dayandığını ifade ederek bütün tümevarımsal akıl yürütmelerde ortak olan geleceğin her zaman geçmişe benzeyeceği ifadesinin rasyonel olarak temellendirilmesinin mümkün olmadığını belirtmektedir. Bu bağlamda, çalışmada tümevarımsal akıl yürütme sonucunda ulaşılan sonuca inanmanın hiçbir rasyonel temelinin olamayacağı yönündeki Hume’un görüşü argüman formunda yeniden yapılandırılarak ortaya konulacaktır.

Nesse artigo, apresento a crítica de Hume de seu Tratado da natureza humana contra a garantia de inferência de causalidade a partir de argumentos de cunho psicológico e de um argumento lógico. Em seguida, são esclarecidos os detalhes da crítica que Popper dirige contra Hume em seu artigo Ciência: Conjecturas e refutações, no qual foca em uma solução do Problema de Hume – considerado como uma faceta do Problema da Demarcação. Explicarei que Popper defende que a ciência avança sempre da (...) teoria em direção à observação – e não o contrário – e que uma atitude crítica em relação às inferências de causalidade pode nos livrar de um dogmatismo irracional. Ainda assim, sustento que Popper está mais para um reformador do pensamento de Hume do que para um demolidor. (shrink)

Tamas Demeter presents a clear and compelling new perspective of Hume’s methodology and conceptual structure in David Hume and the Culture of Scottish Newtonianism. Hume, he argues, is a Newtonian of the Scottish tradition, but not the mechanical kind that is modeled after the Principia. Instead, Hume should be understood as a kind of European Enlightenment “vitalist.” As a result, his work reflects the more organic methodology that defines Newton’s Opticks.

Although the main focus of Hume’s career was in the humanities, his work also has an observable role in the historical development of natural sciences after his time. To show this, I shall center on the relation between Hume and two major figures in the history of the natural sciences: Charles Darwin (1809–1882) and Albert Einstein (1879–1955). Both of these scientists read Hume. They also found parts of Hume’s work useful to their sciences. Inquiring into the relations between Hume and (...) the two scientists shows that his philosophical positions had a partial but constructive role in the formation of modern biology and physics. This is accordingly a clear indication of Hume’s impact on the scientific tradition. Before proceeding to analyze Hume’s contribution to the history of science, it is important to address his broader role in the history of philosophy of science. Hume’s discussions concerning the topics of causation, induction, the distinction between mathematical and empirical propositions, and laws of nature have been important for the philosophy of science of the nineteenth and twentieth centuries.

This chapter examines the relationship between laws and mechanisms as approaches to characterising generalizations and explanations in science. I give an overview of recent historical discussions where laws failed to satisfy stringent logical criteria, opening the way for mechanisms to be investigated as a way to explain regularities in nature. This followed by a critical discussion of contemporary debates about the role of laws versus mechanisms in describing versus explaining regularities. I conclude by offering new arguments for two roles for (...) laws that mechanisms cannot subsume, one epistemically optimistic and one pessimistic, both broadly Humean. Do note that this piece is not primarily Hume exegesis; it is more of a riff in the key of Hume. (shrink)

Reading Tamás Demeter's recent book, "David Hume and the Culture of Scottish Newtonianism," feels like visiting a curiosity shop. There are some general themes that are meant to harmonize the work, such as the emphasis on the conceptual and methodological unity of natural and moral philosophy. This merging of cultures of inquiry is nicely illustrated with the case study of anger in the period. There is the main thesis: that Hume's science of mind was influenced, not as much by Newton's (...) Principia, as by Newton's Opticks. Newton's Opticks informs the "sciences of quality," such as chemistry and physiology in eighteenth-century Scotland, and then chemical and anatomical thinking makes its way to Hume's science of...

There seems a potential tension between Hume’s naturalistic project and his normative ambitions. Hume adopts what I call a methodological naturalism: that is, the methodology of providing explanations for various phenomena based on natural properties and causes. This methodology takes the form of introducing ‘the experimental method of reasoning into moral subjects’, as stated in the subtitle of the Treatise; this ‘experimental method’ seems a paradigmatically descriptive one, and it remains unclear how Hume derives genuinely normative prescriptions from this methodology. (...) -/- In resolving this problem, I will argue that Hume’s naturalistic methodology – that is, his ‘experimental philosophy’ (THN Intro 7), or what has come to be known as his experimental method – consists of the systematisation of phenomena pertaining to human nature. In applying his experimental method to normative subjects, Hume systematises our normative judgments, deriving general principles of normative justification; he then reflexively applies these principles to the pre-philosophical judgments from which they derive, dismissing and/or correcting those that do not accord with his systematised account. I will argue that Hume’s experimental method, far from being wholly descriptive, is in fact thoroughly infused with normativity; furthermore, the very application of this methodology to our normative judgments reveals Hume’s normative ambitions.

I shall argue that when Hume refers to the laws of dynamics, he tacitly assumes a mechanism. Nevertheless, he remains agnostic on whether the hidden micro-constitution of bodies is machinelike. Hence this article comes to the following conclusion. Hume is not a full-blown mechanical philosopher. Still his position on dynamic laws and his concept of causation instantiate a tacitly mechanical understanding of the interactions of bodies.

In a recent paper, Barry Loewer attempts to defend Humeanism about laws of nature from a charge that Humean laws are not adequately explanatory. Central to his defense is a distinction between metaphysical and scientific explanations: even if Humeans cannot offer further metaphysical explanations of particular features of their “mosaic,” that does not preclude them from offering scientific explanations of these features. According to Marc Lange, however, Loewer’s distinction is of no avail. Defending a transitivity principle linking scientific explanantia to (...) their metaphysical grounds, Lange argues that a charge of explanatory inadequacy resurfaces once this intuitive principle is in place. This paper surveys, on behalf of the Humean, three strategies for responding to Lange’s criticism. The ready availability of these strategies suggests that Lange’s argument may not bolster anti-Humean convictions, since the argument rests on premises that those not antecedently sharing these convictions may well reject. The three strategies also correspond to three interesting ways of thinking about relations of grounding linking Humean laws and their instances, all of which are consistent with theses of Humean supervenience, and some of which have been heretofore overlooked.

Hume appeals to different kinds of certainties and necessities in the Treatise. He contrasts the certainty that arises from intuition and demonstrative reasoning with the certainty that arises from causal reasoning. He denies that the causal maxim is absolutely or metaphysically necessary, but he nonetheless takes the causal maxim and ‘proofs’ to be necessary. The focus of this paper is the certainty and necessity involved in Hume’s concept of knowledge. I defend the view that intuitive certainty, in particular, is certainty (...) of the invariability or necessity of relations between ideas. Against David Owen and Helen Beebee, I argue that the certainty involved in intuition depends on the activity of the mind. I argue, further, that understanding this activity helps us understand more clearly one of Hume’s most important theses, namely that experience is the source of a distinct kind of certainty and of necessity.

In the Introduction to the Treatise Hume very enthusiastically announces his project to provide a secure and solid foundation for the sciences by grounding them on his science of man. And Hume indicates in the Abstract that he carries out this project in the Treatise. But most interpreters do not believe that Hume's project comes to fruition. In this paper, I offer a general reading of what I call Hume's ‘foundational project’ in the Treatise, but I focus especially on Book (...) 1. I argue that in Book 1 much of Hume's logic is put in the service of the other sciences, in particular, mathematics and natural philosophy. I concentrate on Hume's negative thesis that many of the ideas central to the sciences are ideas that we cannot form. For Hume, this negative thesis has implications for the sciences, as many of the texts I discuss make evident. I consider and criticize different proposals for understanding these implications: the Criterion of Meaning and the ‘Inconceivability Principle’. I introduce what I call Hume's ‘No Reason to Believe’ Principle, which I argue captures more adequately the link Hume envisions between his logic, in particular his examination of ideas, and the other sciences.

Hume’s views concerning the existence of body or external objects are notoriously difficult and intractable. The paper sheds light on the concept of body in Hume’s Treatise by defending three theses. First, that Hume’s fundamental tenet that the only objects that are present to the mind are perceptions must be understood as methodological, rather than metaphysical or epistemological. Second, that Hume considers legitimate the fundamental assumption of natural philosophy that through experience and observation we know body. Third, that many of (...) the contradictions and difficulties that interpreters attribute to Hume’s concept of body should be attributed instead, as Hume does, to every system of philosophy.

In this paper I try to explain a strange omission in Hume’s methodological descriptions in his first Enquiry. In the course of this explanation I reveal a kind of rationalistic tendency of the latter work. It seems to contrast with “experimental method” of his early Treatise of Human Nature, but, as I show that there is no discrepancy between the actual methods of both works, I make an attempt to explain the change in Hume’s characterization of his own methods. This (...) attempt leads to the question about his interpretation of the science of human nature. I argue that his view on this science was not a constant one and that initially he identified this science with his account of passions. As this presupposes the primacy of Book 2 of his Treatise I try to find new confirmations of the old hypothesis that this Book had been written before the Book 1, dealing with understanding. Finally, I show that this discussion of Hume’s methodology may be of some interest to proponents of conceptual analysis. -/- . (shrink)

The paper addresses two difficulties that arise in Treatise 1.2.5. First, Hume appears to be inconsistent when he denies that we have an idea of a vacuum or empty space yet allows for the idea of an “invisible and intangible distance.” My solution to this difficulty is to develop the overlooked possibility that Hume does not take the invisible and intangible distance to be a distance at all. Second, although Hume denies that we have an idea of a vacuum, some (...) texts in Treatise 1.2.5 are taken by interpreters to suggest that Hume nonetheless believes that there are vacuums in nature. I discuss the relevant texts and defend the view that Hume does not in fact countenance belief in vacuums. I conclude by outlining an interpretation of Hume’s intention in the Treatise that allows us to understand his discussion of ideas as having implications for the sciences. (shrink)

C. Howson’s probabilistic logic as a comprehensive methodological account of scientific inference, which avoids Hume’s inductive skepticism, is discussed against the background of the latter’s quantitative theory of money. Hume’s theory leads to two causal accounts that may appear to be contradictory. As the more general one suggests neutrality of money, while the more descriptive attributes causal influence to specie-flow mechanism of money. The former is grounded by a counterfactual reasoning. The discussion of recent examples of bayesian counterfactual models leads (...) to the conclusion that despite the possibility of a uniform account of Hume’s theory of money, it seems beyond the scope of the Bayesian probabilistic logic offered by Howson.

In this paper I reconstruct the birth, blossoming and decline of an eighteenth century program, namely “Moral Newtonianism”. I reconstruct the interaction, or co-existence, of different levels: positive theories, methodology, worldviews and trace the presence of scattered items of the various levels in the work of Hume, Adam Smith, Adam Ferguson, Dugald Stewart. I highlight how Mirowski’s reconstruction of the interaction between physics and economics may be extended to the eighteenth century in an interesting way once the outdated reconstruction of (...) Adam Smith that has been adopted by Mirowski is updated. I show how general methodological ideas, such as the distinction between ultimate causes or essences and intermediate principles, that originated in a context where the issue was the interaction between natural science and theology, proved useful when transferred to social theory in encouraging a kind of “experimental” approach to social phenomena. I discuss finally the genesis of frozen metaphors such as equilibrium, circulation, and value, arguing that Canguilhem’s lesson – namely that scientific change is produced not only by similarity but also by opposition – may be applied also to the history of economic thought. I take as an example Adam Smith’s ‘discovery’ of social mechanisms vis-à-vis his sceptical mistrust of neo-Stoic and Platonic views of a world-order. (shrink)

Title in English: Of the Methodological Functions of Practices in Hume's Conception of Philosophy.

The relationship between Adam Smith's official methodology and his own actual theoretical practice as a social scientist may be grasped only against the background of the Humean project of Moral Newtonianism. The main features in Smith's methodology are (i) the provisional character of explanatory principles, (ii) 'internal' criteria of truth, (iii) the acknowledgement of an imaginative aspect in principles, with the related problem of the relationship between internal truth and external truth understood as mirroring 'real' causes. Smith's Newtonian (as opposed (...) to Cartesian) methodology makes room for progress in social theorizing as it allows for a decentralization of the various fields of Moral Science, contributing to the shaping of political economy. On the other hand, the Cartesian legacy in Smith's Newtonian methodology makes the relationship problematic between phenomena and principles. (shrink)
