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)
