How does perceptual learning take place early in life? Traditionally, researchers have focused on how infants make use of information within displays to organize it, but recently, increasing attention has been paid to the question of how infants perceive objects differently depending upon their recent interactions with the objects. This experiment investigates 10-month-old infants' use of brief prior experiences with objects to visually organize a display consisting of multiple geometrically shaped three-dimensional blocks created for this study. After a brief exposure (...) to a multipart portion of the display, each infant was shown two test events, one of which preserved the unit the infant had seen and the other of which broke that unit. Overall, infants looked longer at the event that broke the unit they had seen prior to testing than the event that preserved that unit, suggesting that infants made use of the brief prior experience to (a) form a cohesive unit of the multipart portion of the display they saw prior to test and (b) segregate this unit from the rest of the test display. This suggests that infants made inferences about novel parts of the test display based on limited exposure to a subset of the test display. Like adults, infants learn features of the three-dimensional world through their experiences in it. (shrink)

Salmon farming is a rapidly expanding industry. In order for it to develop in an ethical manner, many ethical issues must be confronted. Among these are questions regarding the quality of life of salmon on farms. To develop reasonable answers to these questions considerable thought must be devoted to developing appropriate standards of care for salmon. If these questions are not addressed the results could be bad both for salmon and for salmon farmers.

Late nineteenth‐century opponents of atomism questioned whether the evidence required any notion of an atom. In this spirit, Duhem developed an account of the import of chemical formulas that is clearly neutral on the atomic question rather than antiatomistic. The argument is supplemented with specific inadequacies of atomic theories of chemical combination and considerably strengthened by the theory of chemical combination provided by thermodynamics. Despite possible counterevidence available at the time, which should have tempered some of Duhem's concluding remarks, there (...) was no atomic theory of chemical combination, which is wholly a product of the twentieth century. †To contact the author, please write to: Department of Philosophy, University of Stockholm, SE‐106 91 Stockholm, Sweden; e‐mail: paul.needham@philosophy.su.se.

This undergraduate textbook introduces some fundamental issues in philosophy of science for students of philosophy and science students. The book is divided into two parts. Part 1 deals with knowledge and values. Chap. 1 presents the classical conception of knowledge as initiated by the ancient Greeks and elaborated during the development of science, introducing the central concepts of truth, belief and justification. Aspects of the quest for objectivity are taken up in the following two chapters. Moral issues are broached in (...) Chap. 4, which discusses some aspects of the use and abuse of science, taking up the responsibilities of scientists in properly conducting their business and decision-makers in their concerns with the import of science for society. Part 2 contrasts the view of scientific progress as the rejecting of old hypotheses and theories and replacing them with new ones, represented by Karl Popper, with the conception of progress as accumulating knowledge, saving as much as possible from older theories, represented by Pierre Duhem. A concluding chapter defends the natural attitude of taking the theories of modern science to be literally true, i.e. realism, in the face of arguments drawn partly from the history of scientific progress in criticism of this stance.

In discussions about the Scientific Revolution, a key expression is “modern science”. Its traditional understanding – mathematization and experimentation – is too weak: Euclid’s geometry and Archimedes’ physics were both perfectly mathematical and were based on objective experience. And it is too strong: in natural sciences beyond physics, math is quite limited. Joseph Needham in his Grand Question actually focused on modern physics originating with Galileo. To make this question really historical, it is narrowed down to physics and expanded (...) in cultural time and space: Which feature of modern physics, absent in Greco-Roman and Medieval sciences, prevented the next major advance after Archimedes, and prevented non-Europeans to join modern science for centuries after Galileo and up to the 20th century? In modern physics, besides the tools of mathematics and experiment, no less important is the third tool, described by Einstein as "the boldest speculation [to] bridge the gaps between the empirical data." This tool implies belief in the hidden fundamental laws of the universe and the right to invent fundamental concepts that are not directly observable, but can be tested experimentally along with the theory based on them. Such a belief, or the postulate of modern science, is the key distinction of modern physics. Among the great modern physicists there were eight theorists who successfully invented new fundamental concepts. And each of these inventions led to breakthrough advances of modern physics. (shrink)

When Bouvet discovered the relationship between the binary arithmetic of Leibniz and the hexagrams of the I ching—in reality only a purely formal correspondence—he sent to Leibniz a woodcut diagram of the Fu-Hsi arrangement, which provides the key to the analogy. This diagram, in a re-drawn version, was first published by Gorai Kinzō in a study of Leibniz's interpretation of the I ching and Confucianism which has been influential in providing, indirectly, the principal source for the accounts of Wilhelm and (...) Needham. Yet this pioneering study of Leibniz's interpretation of the hexagrams is virtually unknown. Even the account of Needham, who saved it from complete obscurity, contains one or two inaccuracies about it and these are repeated by Zacher in his otherwise excellent monograph on Leibniz's binary arithmetic.

Nearly every edition of Aeschylus published between 1782 and 1852 contained readings from what were called ‘Askew's collations’ or the ‘Askew MSS.’—usually referred to as Ask. A, Ask. B, Ask. C, Ask. D, Ask. a, Colb. 1, and Colb. 2. These MSS., which were very briefly described, were stated in these editions to be Paris MSS. which had been collated by Askew. Blomfield, however, discovered that Askew had transcribed all the collations from a note-book that had belonged to Needham, (...) and Pierron accused Askew of deliberate plagiarism and unscrupulous dishonesty. The late Prof. H. W. Smyth in a recent note on the subject attempted to identify the ‘Askew MSS.’, and maintained the charge of plagiarism; but his conclusions were based on inadequate evidence, and were consequently partly incorrect. A full study of all the available evidence, a summary of which I give below, not only clears Askew's name of any plagiarism, but also establishes the identity of the MSS. (shrink)

If the arguments of Edward Said's "Orientalism" are valid, Joseph Needham's "Science and Civilisation in China" stands condemned. The opposition between Foucault, Said's main source of inspiration, and both Marxism and hermeneutics is highlighted. Utilizing the work of MacIntyre, recent hermeneutic philosophy is defended against Foucault, and through this, Needham's work is defended as a form of Marxist hermeneutics.

What, precisely, is `salt'? It is a certainwhite, solid, crystalline, material, alsocalled sodium chloride. Does any of that solidwhite stuff exist in the sea? – Clearly not.One can make salt from sea water easily enough,but that fact does not establish thatsalt, as such, is present in brine. (Paper andink can be made into a novel – but no novelactually exists in a stack of blank paper witha vial of ink close by.) When salt dissolves inwater, what is present is no (...) longer `salt' butrather a collection of hydrated sodium cationsand chloride anions, neither of which isprecisely salt, nor is the collection. Theaqueous material in brine is also significantlydifferent from pure water. Salt may beconsidered to be present in seawater, but onlyin a more or less vague `potential' way.Actually, there is no salt in the sea. In bothancient and modern treatments of otherimportant chemical concepts, including thenotions of `element', related complication,especially polysemy (terms with multiplemeanings), also occurs.In a recent paper, Paul Needham discussed the(predicable) properties of chemical substances,phases, and solutions. He provided a valuablecharacterization of cases in which severalquantities occupy the same space. He alsoconcluded that solution properties are not`intensive', because solvent and solute do nothave parts in common. He tacitly assumed thatingredients are not altered by their inclusionin a solution. This may be the case in somespecial cases (deutero-benzene dissolved inbenzene, say) but is not true in general – andcertainly does not apply to the case of brine,which Needham used as an example – since theions that exist in the solution, and also theaqueous material there, are quite differentfrom the pure ingredients used in making thesolution. An adequate theory of wholes andparts (mereology) must take into account thatwhen individuals enter combinations ofinteresting sorts they no longer are the verysame individuals that existed prior to thecomposition. It appears that no such formaltheory now actually exists. (shrink)

Cosa significa credere? Qual è l’utilità della credenza? Per analizzare il contenuto delle credenze di un popolo possiamo prescindere dallo studio della cultura di quel popolo? I termini da noi adoperati hanno un contenuto semantico unico e unicamente determinato? Per rispondere a tali fondamentali interrogativi, l’Autrice analizza i concetti di credere e di credenza secondo il punto di vista dell’antropologo britannico Rodney Needham e l’attenzione viene rivolta principalmente al suo enorme debito intellettuale nei confronti del filosofo viennese Ludwig Wittgenstein.

The contrast between the strategies of research employed in reductionism and holism masks a radical contradiction between two different scientific philosophies. We concentrate in particular on an analysis of the key philosophical issues which give structure to holistic thought. A first (non-exhaustive) analysis of the philosophical tradition will dwell upon: a) the theory of emergence: each level of organisation is characterised by properties whose laws cannot be deduced from the laws of the inferior levels of organisation (Engels, Morgan); b) clarification (...) of the relations between the “whole” and the “parts” (Woodger, Needham); c) the ontological or epistemological nature of the emergent properties; are they a phenomenological reality or solely an artefact of the state of our knowledge? (Pepper, Henle, Hempel and Oppenheim); d) the proposition of the holistic theoretical and methodological model ( Novikoff, Feibleman). I then go on to examine the differences that exist between the reductionist and the holistic approaches at various levels of analysis: that is to say, the differences which affect their ontologies, methodologies and epistemologies respectively. I attempt to understand the spirit of a holistic approach to ecology by analyzing the major work of E.P. Odum Fundamentals of ecology (1953, 1959, 1971). I set forward what might be meant by the “holistic approach”, which is implicated in all the different levels of organisation at which the problem of “complexity” is debated. Ecology presents itself as an “holistic science” and Odum’s book offers a vision of the world which dates far back in the history of philosophy. By looking at the three different editions of this fundamental text on ecology, we may become aware of the evolution of Odum’s thought. In fact, only in the third and last edition is there a conscious appropriation of the holistic approach (by using the theoretical models of Feibleman who, for his part, refers to Novikoff). However, even when formally referring to the theory of emergence (that is to say the ontological nucleus of every holistic approach), Odum’s systemic analysis presents the same logical errors, which push him back into the reductionist domain. Above all, in his examination of the main concepts of “population”, “community” and “ecosystem”, there is a misunderstanding of the profound difference between “collective properties” and “emergent properties”. Moreover, the cybernetic models of Odum’s systemic analysis (introduced into ecology by Margalef), allowed him to vastly oversimplify his methodological task: in fact, neither how many levels nor which levels of organization are fundamental for the study of each individual level is clearly marked. Finally, Odum analyses the ecosystem as composed of energetic flux and cycles of matter, referring to the trophic-dynamic vision of Lindeman. That is to say, in my opinion, he juxtaposes a reductionistic methodology and epistemology to an holistic ontology. (shrink)

Tutte le dottrine tradizionali, da quelle più arcaiche e "primitive" a quelle più evolute e articolate, hanno sempre affermato che l'uomo non è un essere solamente corporeo, sia pur dotato di ingegno e di intelligenza, ma è un essere dalla natura composita, formato da una parte materiale e da una o più componenti invisibili e "sottili" e che in lui risiede un principio immortale di origine divina o comunque soprannaturale. Secondo il modo di vedere tradizionale, l'uomo, per conoscere e realizzare (...) se stesso, deve pertanto prendere coscienza, in primo luogo ed essenzialmente, di questa sua natura di essere composito e immortale, e questa è una di quelle idee universali (per noi forse la più importante) che troviamo diffuse presso tutte le popolazioni del pianeta, anche se con sfumature diverse nelle varie tradizioni..."--Cover flap.

A highly contentious issue in recent philosophy of logic has been the question of whether there can be contingently true identity statements. In this paper I want to investigate a possible loop-hole in the standard argument of the necessitarians (i.e., those who maintain that any true identity statement is necessarily true).

This essay defends the view that “modern science,” as with modernity in general, is a polycentered phenomenon, something that appears in different forms at different times and places. It begins with two ideas about the nature of rational scientific inquiry: Karin Knorr Cetina's idea of “epistemic cultures,” and Philip Kitcher's idea of science as “a system of public knowledge,” such knowledge as would be deemed worthwhile by an ideal conversation among the whole public under conditions of mutual engagement. This account (...) of the nature of scientific practice provides us with a new perspective from which to understand key elements in the philosophical project of Jaina logicians in the seventh, eighth, and ninth centuries c.e. Jaina theory seems exceptionally well targeted onto two of the key constituents in the ideal conversation—the classification of all human points of view and the representation of end states of the deliberative process. The Buddhist theory of the Kathāvatthu contributes to Indian epistemic culture in a different way: by supplying a detailed theory of how human dialogical standpoints can be revised in the ideal conversation, an account of the phenomenon Kitcher labels “tutoring.” Thus science in India has its own history, one that should be studied in comparison and contrast with the history of science in Europe. In answer to Joseph Needham, it was not ‘modern science’ which failed to develop in India or China but rather non-well-ordered science, science as unconstrained by social value and democratic consent. What I argue is that this is not a deficit in the civilisational histories of these countries, but a virtue. (shrink)

The analysis of philosophically important themes can depart from two different angles. The first one investigates the various answers that have been given to a certain issue, like that of the problem of knowledge, the justification of theories, the notion of culture, etcetera. These answers are often mutually contradictory which, by the way, facilitates their overview (like the schemes of rationalism-empiricism, justification-discovery, universalism-relativism). A second approach starts from the problems (or: “problematique”) behind the divergent answers (e.g., foundationalism behind both, empiricism (...) and rationalism).In the following sections the issue of discovery is discussed. Here the second line of approach has been followed, not only by making visible a same problematique, but more by trying to set out the common context of the discussion about context of discovery and context of justification. The idea is that this discussion, or better the shift taking place in that discussion, finds its reason in a context in which the distance between traditional methodology and contemporary scientific practice, also between scientific knowledge and the experience of reality has become greater. This is related to the deepening awareness of the cultural context of scientific method. Man and world, scientific method and cultural context are always interacting.From this point of view quite different philosophical approaches show nevertheless similar features pointing to new solutions. A more psychological approach to scientific method (like: Gordon's and Grmek's, even perhaps Gutting's reinterpretation of Popper) and a sociological one (e.g., Barnes, Bloor, and already Durkheim) are opposed to a more logically structured analysis of Nagel, Hempel, and also Popper. Nevertheless the view on the flexibility of scientific method defended along different lines by for instance Achinstein, Bachelard, Hesse, Piaget, Polanyi, Toulmin manifests a certain convergence in those divergent standpoints, the more so since often the cultural context of science is being stressed (e.g., Ladriére, Prigogine, Needham).The miscellany of philosophical orientations, presented in the following sections, can in this way perhaps give profile to deeper tendencies: to relate again scientific method to the context of culture and of human strategy in general. This does not blend, however, the distinction between context of justification and context of discovery. By changing their roles a new overview of this dilemma becomes possible. There is no juxtaposition of both, nor has the one to be absorbed by the other. The conclusion will be that there are still two contexts, but that one is wider, less defined and demarcated from the wider field of daily culture, and that the other is more restricted, functioning as a kind of safetydevice on behalf of the wider strategy of discovery. In such a way discovery is regarded as the wider context of the more restricted context of justification. (shrink)

A moving cultural biography of abolitionist martyr John Brown, by one of the most important African-American intellectuals of the twentieth century. In the history of slavery and its legacy, John Brown looms large as a hero whose deeds partly precipitated the Civil War. As Frederick Douglass wrote: "When John Brown stretched forth his arm... the clash of arms was at hand." DuBois's biography brings Brown stirringly to life and is a neglected classic.

Throughout the long history of Classic Maya hieroglyphs, a logosyllabic writing system used from the late first millennium BCE through the mid-second millennium CE in southern Mesoamerica, the most commonly recorded phonetic value was the syllable u (/ʔu/). With over a dozen different u hieroglyphs, Classic Maya scribes had more options for recording /ʔu/ than any other syllable or logograph. Cognitive approaches to writing systems typically attribute graphemic variation (i.e., alternation between signs with equivalent linguistic value) to semantic differences like (...) animacy or to non-linguistic factors like identity. Distribution of Classic Maya u hieroglyphs, however, suggests that morphosyntactic context influenced which grapheme scribes wrote and when. This case suggests that scribal knowledge of Classic Maya hieroglyphs included ideas about writing's relationship to language. It also highlights the cognitive relevance of morphosyntax for a writing system's users as they differentiate among graphic signs with identical linguistic denotation. (shrink)
