  But Milne, Eddington, and Dirac had their supporters as well. N.R. Campbell, whose theory of science was already well-known, makes an uncontroversial interpretation of the affair. “Science” he begins, “(or at least physics) has long consisted of two distinct but complementary activities”, one of which is experimental and empirical; “its procedure is induction.” The other activity attempts to provide explanations of scientific laws, which explanations have the “pecularity” that “they often (not always) predict new laws in addition to explaining old ones.” Campbell cannot resist ending on an ad hominem of his own: “If he [Dingle] does not deem it important to observe the distinction between what is and what is not demonstrable experiment, surely he should welcome a movement to amalgamate the Royal with the Aristotelian Society.” Indeed.
