  Eddington disparages these same methods. In his scathing Nature review of Milne’s book, he rejects Milne’s hypothetico-deductivism, his cosmological principle, and, above all, his operationalism: “When I visit the Cavendish Laboratory, I do not find its occupants engaged in flashing light-signals at each other, but I find practically everyone employing rigid scales or their equivalent” (Eddington 1935, p. 636). Whittaker’s review was not so negative as Eddington’s (Whittaker 1935). While the senior physicist rejects Milne’s operationalism and attacks upon the geometrical commitments of relativistic proponents, he is considerably more forgiving about Milne’s hypothetico-deductivism, and even goes so far as to remark Milne’s “brilliant record in astrophysical discovery.” Nonetheless, Milne’s break with a tradition including at least “Einstein, de Sitter, Friedmann, LeMaître, Weyl, Eddington, H.P. Robertson and others” is to be regretted (Whittaker 1935 p. 179). Perhaps, along with Eddington, Whittaker hopes that soon “Professor Milne will return to orthodoxy” (Eddington 1935, p. 636).
