History of science, it has been argued, has benefited philosophers of science primarily by forcing them into greater contact with "real science." In this paper I argue that additional major benefits arise from the importance of specifically historical considerations within philosophy of science. Loci for specifically historical investigations include: (1) making and evaluating rational reconstructions of particular theories and explanations, (2) estimating the degree of support earned by particular theories and theoretical claims, and (3) evaluating proposed philosophical norms for the (...) evaluation of the degree of support for theories and the worth of explanations. More generally, I argue that theories develop and change structure with time, that (like biological species) they are historical entities. Accordingly, both the identification and the evaluation of theories are essentially historical in character. (shrink)

The publication of L. Pearce Williams's definitive biography of Faraday has led to lively discussion of the influence of Naturphilosophie on Davy and Faraday, and of the role played by Bosco vichean atomism in their scientific development. In a recent article J. Brookes Spencer argued that Boscovich's force law, involving interaction between point atoms independent of surrounding particles, was only compatible with Faraday's view of gravity and not with his views on other forces. This would of course contradict the notion (...) of unity which is absolutely fundamental to Boscovich's Theoria. (shrink)

In the late eighteenth century Newton's Principia was studied in the Scottish universities under the influence of the local school of ‘Common Sense’ philosophy. John Robison, holding the key chair of natural philosophy at Edinburgh from 1774 to 1805, provided a new conception of ‘mechanical philosophy’ which proved crucial to the emergence of physics in nineteenth century Britain. At Cambridge the emphasis on ‘mixed mathematics’ was taken to a new level of refinement and application by the introduction of analytical methods (...) in the 1820s. The fusion of these two schools, with emphasis on conceptual unity on the one hand, and mathematisation on the other, came about from the 1830s onwards, and reached full expression in the new framework of a unified mathematical physics based on the energy principle.

In recent years a number of scholars have argued that Faraday's theories of matter and force were founded on concepts which were derived from Boscovich'sTheoria Philosophiae Naturalis(1758). The notion that Faraday's ideas display Boscovichean tendencies is not a new one: it was proposed by several of Faraday's immediate successors and has been noted by more recent commentators. Statements of this kind are not implausible as assertions of a general correspondence between Faraday's views on matter, as expressed in the “Speculation touching (...) Electric Conduction and the Nature of Matter” of 1844, and Boscovich's theory of point atomism, but Professor L. Pearce Williams has made much stronger claims for the dependence of Faraday's ideas on Boscovich's theory of matter. Williams' interpretation has been questioned by recent scholarship, and in this paper I wish to advance an alternative interpretation of Faraday's ideas on electricity and the nature of matter.
