This book exhibits deep philosophical quandaries and intricacies of the historical development of science lying behind a simple and fundamental item of common sense in modern science, namely the composition of water as H2O. Three main phases of development are critically re-examined, covering the historical period from the 1760s to the 1860s: the Chemical Revolution, early electrochemistry, and early atomic chemistry. In each case, the author concludes that the empirical evidence available at the time was not decisive in settling the (...) central debates and therefore the consensus that was reached was unjustified or at least premature. This leads to a significant re-examination of the realism question in the philosophy of science and a unique new advocacy for pluralism in science. Each chapter contains three layers, allowing readers to follow various parts of the book at their chosen level of depth and detail. The second major study in "complementary science", this book offers a rare combination of philosophy, history and science in a bid to improve scientific knowledge through history and philosophy of science.

The periodic table of the elements is one of the most powerful icons in science: a single document that captures the essence of chemistry in an elegant pattern. Indeed, nothing quite like it exists in biology or physics, or any other branch of science, for that matter. One sees periodic tables everywhere: in industrial labs, workshops, academic labs, and of course, lecture halls. It is sometimes said that chemistry has no deep ideas, unlike physics, which can boast quantum mechanics and (...) relativity, and biology, which has produced the theory of evolution. This view is mistaken, however, since there are in fact two big ideas in chemistry. They are chemical periodicity and chemical bonding, and they are deeply interconnected. The observation that certain elements prefer to combine with specific kinds of elements prompted early chemists to classify the elements in tables of chemical affinity. Later these tables would lead, somewhat indirectly, to the discovery of the periodic system, perhaps the biggest idea in the whole of chemistry. Indeed, periodic tables arose partly through the attempts by Dimitri Mendeleev and numerous others to make sense of the way in which particular elements enter into chemical bonding. (shrink)

This work develops an epistemology of measurement, that is, an account of the conditions under which measurement and standardization methods produce knowledge as well as the nature, scope, and limits of this knowledge. I focus on three questions: (i) how is it possible to tell whether an instrument measures the quantity it is intended to? (ii) what do claims to measurement accuracy amount to, and how might such claims be justified? (iii) when is disagreement among instruments a sign of error, (...) and when does it imply that instruments measure different quantities? Based on a series of case studies conducted in collaboration with the US National Institute of Standards and Technology (NIST), I argue for a model-based approach to the epistemology of physical measurement. To measure a physical quantity, I argue, is to estimate the value of a parameter in an idealized model of a physical process. Such estimation involves inference from the final state (‘indication’) of a process to the value range of a parameter (‘outcome’) in light of theoretical and statistical assumptions. Contrary to contemporary philosophical views, measurement outcomes cannot be obtained by mapping the structure of indications. Instead, measurement outcomes as well as claims to accuracy, error and quantity individuation can only be adjudicated relative to a choice of idealized modelling assumptions. (shrink)

It is often assumed that chemistry was a typical positivistic science as long as chemists used atomic and molecular models as mere fictions and denied any concern with their real existence. Even when they use notions such as molecular orbitals chemists do not reify them and often claim that they are mere models or instrumental artefacts. However a glimpse on the history of chemistry in the longue durée suggests that such denials of the ontological status of chemical entities do not (...) testify for any specific allegiance of chemists to positivism. Rather it suggests that the dilemma positivism vs realism is inappropriate for characterizing the ontology of chemistry. This alternative shaped at the turn of the twentieth century in the context of controversies about atomic physics does not take into account the major concern of chemists, i.e. making up things. Only by considering what matters for chemists, their matters of concern rather than their matter theories, can we expect to get an insight on their ontological assumptions. The argumentation based on historical data is twofold. It is wellknown that generating new substances out of initial ingredients which is the raison d'être of chemistry raised a vexing puzzle which has been alternatively solved with the Aristotelian notion of mixt and the Lavoisieran notion of compound. I argue that an essential tension remains intrinsic in chemistry between the two conceptual frameworks. The second section tries to make sense of the long tradition in chemistry of ontological noncommitment. I argue that what is usually considered as a denial of the existence of the basic units of matter would be better characterized as a focus on more important actors on the chemical stage. (shrink)

Normal 0 21 false false false MicrosoftInternetExplorer4 st1:*{behavior:url } This part of the Soviet philosophy that corresponds approximately to theoretical philosophy and philosophy of science on the example of Estonia and proceeding from the University of Tartu is discussed. The author concentrates on the period of approximately 1960–1990, when he himself was engaged in the field, i.e. the time before 1960 is not included. The aim of this paper is not to provide an overview of the individual philosophers in Estonia (...) at the time and their works, but to give a more general description of the philosophy of the Soviet era. The Soviet and the East European philosophy of the time have received rather little critical treatment in literature in English. However, a few general overviews trying to prove that this Soviet and East European philosophical legacy is worth studying have still been published. This paper is focused on the question what kind of philosophical researches it was possible to engage oneself in under the abnormal conditions at the time and whether some starting points and problem issues in theseresearches might be viable also today. Estonian experience confirms the general conclusion of these authors who, analyzing the legacy of Marxism, have found that although Marxism is nowadays—not to mention how it existed in the Soviet totalitarian regime—mainly not considered a serious philosophy but rather an ideological basis of a failed political doctrine, it has nevertheless quite something to offer when treated in a more depoliticized manner, in the general context of philosophical quests. Teoreetiline ja teadusfilosoofia Nõukogude ajal: mõned märkused Eesti näitel 1960-1990 Vaatluse all on Eesti näitel ja lähtudes Tartu ülikoolist see osa Nõukogudeaegsest filosoofiast, mis vastab umbes teoreetilisele filosoofiale ja teadusfilosoofiale. Autor peatub ajavahemikul umbes 1960–1990, mil ta ka ise tegev oli, st 1960-ndate aastate eelset aega ei käsitleta. Artikli eesmärgiks ei ole ülevaate andmine Eestis sel ajal tegutsenud filosoofidest ja nende töödest, vaid Nõukogudeaegse filosoofia üldisem iseloomustamine. Nõukogude ja selleagset Ida-Euroopa filosoofiat on ingliskeelses kirjanduses üsna vähe kriitiliselt uuritud. Üksikuid ülevaateteoseid, milles on püütud näidata, etsee Nõukogude ja Ida-Euroopa filosoofiline pärand väärib uurimist, on siiski ilmunud. Käesolevas artiklis on keskendutud eelkõige küsimusele, mis laadi filosoofilise uurimistööga sai tolle aja ebanormaalsetes tingimustes tegelda ja kas mõned lähtekohad ja probleemipüstitused selles on elujõulised ka veel nüüd. Eesti kogemus kinnitab nende autorite üldist järeldust, kes marksismi pärandit uurides on leidnud, et kuigi marksismi tänapäeval — rääkimata sellest, missugune see oli Nõukogude totalitaarses režiimis — enamasti ei peeta tõsiseltvõetavaks filosoofiaks, vaid pigem läbikukkunud poliitilise õpetuse ideoloogiliseks aluseks, on tal siiski nii mõndagi öelda, kui teda käsitleda depolitiseeritumalt, filosoofiliste otsingute üldises kontekstis. Märksõnad: dialektiline materialism, dialektika, ‘eessõna-marksism’, filosoofia põhiküsimus, Nõukogude filosoofia, ‘ontologistid’ ja ‘epistemologistid’, praktika. (shrink)

Whitehead’s and Prigogine’s philosophies of science are similar in this respect that they both areinterested in ontology built in the light of modern science. This kind of ontological approach, especially Whitehead’s metaphysical reasoning is usually regarded as speculative which should be avoidedin philosophy of science. Ilya Prigogine and Isabelle Stengers appreciated, however, Whitehead’s metaphysics as cosmology in that being the most ambitious attempt to elaborate a philosophy of naturethat, although speculative, is not directed against science or towards separation of philosophy (...) fromthe actual science. Although Whitehead criticized the classical science, he did not identify it withscience in general and did not acknowledge the respective domains and tasks of science and philosophy as distinct of principle from each other. According to Prigogine and Stengers Whitehead’s philosophy was somewhat the forerunner of Prigogine’s non-classical science which gives a new content to thespeculations of Whitehead. Chemistry was a starting point of Prigogine’s non-classical physical theory.In the present paper Prigogine’s conception of non-classical science is examined from the point ofview of a theoretical conception of science elaborated in the context of philosophy of chemistry.Prigogine and Stengers, as well as Whitehead, have not really presented a theoretical conception ofscience. It is argued that the latter, however, offers a key for examining various issues in philosophy ofscience and understanding science in general, including Prigogine’s non-classical science. Appreciating Prigogine’s optimism concerning the chances of science that has liberated itself from the myth,the author still finds that this optimism can also be misleading as it can create a false impression thatthis new science does not deal with idealizations any more, that it is not a means of inquiry resultingfrom special requirements and aims, but will really understand the world “as it is” to the point thatthe problems of so called human world, including those of, e.g., ethics would be, in principle, scientifically understandable. In fact, however, if non-classical science manages rid itself from the myth ofclassical science, the only change will be that it does not equate the scientific picture of world andscientifically modelled reality with the real world “as it is”.Keywords: non-classical science, philosophy of chemistry, Prigogine’s scientific ontology, theoretical model of science, Whitehead’s metaphysical ontology.

Between 1869 and 1871, D. I. Mendeleev, a teacher at the University at St Petersburg published a textbook of general chemistry intended for his students. The title, Principles of Chemistry was typical for the time: it meant that chemistry was no longer an inquiry on the ultimate principles of matter but had become a science firmly established on a few principles derived from experiment.

Kripke has argued that definitions of units of measurements provide examples of statements that are both contingent and a priori. In this paper I argue that definitions of units of measurement are intended to be stipulations of what Kripke calls "theoretical identities": a stipulation that two terms will have the same rigid designation. Hence such a definition is both a priori and necessary. The necessity arises because such definitions appeal to natural kind properties only, which on Kripke's account are necessary.
