The philosophy of measurement studies the conceptual, ontological, epistemic, and technological conditions that make measurement possible and reliable. A new wave of philosophical scholarship has emerged in the last decade that emphasizes the material and historical dimensions of measurement and the relationships between measurement and theoretical modeling. This essay surveys these developments and contrasts them with earlier work on the semantics of quantity terms and the representational character of measurement. The conclusions highlight four characteristics of the emerging research program in (...) philosophy of measurement: it is epistemological, coherentist, practice oriented, and model based. (shrink)

Weighing of experience was a central concern of what Bacon called the “literate” stage of experimentation. As early as 1608, Bacon devised precise tenets for standard, quantitative reporting of experiments. These ideas were later integrated into his experimental histories proper. Bacon’s enquiry of dense and rare is the best example of experientia literata developed in a quantitative fashion. I suggest that Bacon’s ideas on this issue can be tied to experiments for the determination of specific gravities born in a monetary (...) context: Bacon’s investigation was very likely a generalization of Jean Bodin’s experiments in Universae naturae theatrum. Overall, Bacon’s program of quantification calls for a revision of established historiographical notions, especially Thomas Kuhn’s sharp dichotomy between a mathematical and a Baconian experimental tradition in seventeenth-century science.

The paper examines the copious correspondence between the English philosopher John Locke and the French intellectual Nicolas Toinard ; Locke made the acquaintance of Toinard in Paris in 1677 or early in 1678, and the latter remained his lifelong friend and most assiduous correspondent. An Orléanais and a devout Catholic, Toinard combined an intense interest in the Scriptures with an enthusiasm for experimental science and inventions of every kind; he introduced Locke to all the French official institutions and to a (...) number of private laboratories. Toinard’s principal work, Evangeliorum Harmonia Graeco-Latina, was greatly appreciated by Locke for its new method. The paper attempts to explore the bulk of this correspondence in detail, giving an account of the wide range of topics dealt with in the two hundred letters; it is divided into four paragraphs referring, respectively, to the years 1678-1679, 1679-1681, 1681-1686, 1686-1704. The perspective is diachronic; on some occasions, the focus is on a particular topic which is the object of prolonged discussion between the two correspondents. In the conclusion, attention is drawn to the relevance of this correspondence in the context of the 17th century and of Locke’s philosophical thought. (shrink)

Although historians have long recognized the importance of long-range scientific expeditions in both the practice and culture of eighteenth- and nineteenth-century science, it is less well understood how this form of scientific organization emerged and became established in the seventeenth and early eighteenth centuries. In the late seventeenth century new European scientific institutions tried to make use of globalized trade networks for their own ends, but to do so proved difficult. This paper offers a case history of one such expedition, (...) the voyage sponsored by the French Académie royale des sciences to Gorée and the Caribbean islands of Guadeloupe and Martinique in 1681–3. The voyage of Varin, Deshayes and de Glos reveals how the process of travel itself caused problems for instruments and observers alike. (shrink)
