The increasing attention which has been given to social history of science and to the sociological analysis of scientific activity has resulted in a renewed interest in scientific controversies. Furthermore, the rejection of the presentist view of history, according to which those contestants who took what we can identify, with the benefit of modern knowledge, as the ‘right’ stand in a controversy, were right and their opponents were ‘wrong’, left the subject of scientific controversies with many questions. What determines their emergence, course and resolution? When Froggatt and Nevin wrote on the Bio-metric-Mendelian controversy in 1971 they called their article ‘descriptive rather than interpretative’, so they avoided the very questions we would like to ask. Provine, in the same year, concentrated on the strong personalities of the contestants, their clashes, and the scientific arguments in play. But in 1975 Mackenzie and Barnes argued that the controversy could not be accounted for unless recourse was had to sociological factors. Their view has become widely known and figured prominently in 1982 in Steven Shapin's recital of the empirical achievements of the application of the sociological approach. I have returned to this subject because I do not yet feel altogether convinced by Mackenzie and Barnes' analysis. Even if their analysis of the controversy between Pearson and Bateson be accepted, it is not so obvious how effectively it can be used to explain the controversy between Weldon and Bateson, and I am not confident that it is adequate for an understanding of the evolution of their differing views of the mechanism of evolution.

This is the German translation (referred to in future as Kontroverse) of the unpublished English typescript: ‘Historical and Sociological Analyses of Scientific Change: The Case of the Mendelian-Biometrician Controversy in England’, pp. 1–66, which the authors duplicated and distributed in 1974. The reason for giving this source precedence over later more accessible papers is that it offers the most detailed account of their analysis of this debate. However, we shall refer to the revised account by Mackenzie in 1981 (see note 20). The authors' essay: ‘Scientific Judgement: The Biometry-Mendelism Controversy’, in Barnes, S.B. and Shaplin, S.

38 Crowther, J.G., British Scientists of the Twentieth Century, London, 1952, p. 256.Google Scholar Crowther states on p. 289: ‘He [Bateson] was of comfortable middle-class Liberal origin, descended from well-to-do North of England trading families. He was not well-off himself, but he had the ideology of a class which regarded automatic provision of living and education for its members as one of their natural rights’.
39 Kontroverse, p. 180Google Scholar, English text, p. 36. Barnes went so far as to suggest that Bateson's hostility to eugenics was engendered by the interests of class and occupation dependent upon the traditional order, land rather than manufacture, the country rather than the city, scriptural rather than scientistic authority…' Barnes, , op. cit. (25), p. 60Google Scholar. Presumably he was referring to Bateson's membership of St John's College Cambridge, a wealthy land-owning, Anglican foundation. Bateson, like the other Mendelians, was not a landowner, and he was decidedly agnostic towards religion.
40 As others have pointed out, Bateson did not agree with the old academic élite on the subject of university degrees for women.
