James Clerk Maxwell's electromagnetic theory famously unified many of the Victorian laws of physics. This essay argues that Maxwell saw a deep theological significance in the unification of physical laws. He postulated a variation on the design argument that focused on the unity of phenomena rather than Paley's emphasis on complexity. This argument of Maxwell's is shown to be connected to his particular evangelical religious views. His evangelical perspective provided encouragement for him to pursue a unified physics that supplemented his other philosophical, technical and social influences. Maxwell's version of the argument from design is also contrasted with modern ‘intelligent-design’ theory.

25 Despite his prominence, Paley's version of the design argument was certainly not the only one used in the Victorian period. For examples, see D.W. Bebbington, ‘Science and evangelical theology in Britain from Wesley to Orr’, in David N. Livingstone, D.G. Hart and Mark A. Noll (eds.), Evangelicals and Science in Historical Perspective, New York: Oxford University Press, 1999, pp. 120–141, 133; Jonathan Topham, ‘Science, natural theology, and evangelicalism in early nineteenth-century Scotland’, in Livingstone, Hart and Noll, op. cit., pp. 142–174; Yeo Richard, ‘The principle of plenitude and natural theology in nineteenth-century Britain’, BJHS (1986) 19, pp. 263–82; as well as Topham's unpublished PhD dissertation, ‘An infinite variety of arguments’, Lancaster University, 1993.
26 Maxwell did make the case that science could not explain the beginning of the universe, but this was actually not distinctive of his design argument: this inability was agreed upon by agnostic and atheistic scientists such as T.H. Huxley and John Tyndall as well.

31 Different rates of change for particular elements of science are discussed in Peter Galison, How Experiments End, Chicago: University of Chicago Press, 1987, pp. 246–57. In Galison's terms, Maxwell would say that science and religion should harmonize their ‘long-term constraints’.

43 There is an anecdote from Karl Pearson presenting Maxwell as a biblical literalist quoted in Smith, op. cit. (7), p. 307. This story is quite different from the other evidence we have about Maxwell's religious beliefs and outlook. I would infer that Pearson confused Maxwell's deep respect for scripture for a slavish literalism. Maxwell was certainly not averse to interpreting biblical passages (see Maxwell to Charles John Ellicott, Bishop of Gloucester and Bristol, 22 November 1876, SLP, vol. 3, pp. 416–8).
