Elton The Practice of History (1967) Positivism in historical writing has been under attack for many decades now -at least since the publication of Hayden White's Metahistory in 1973, and the broader 'linguistic turn' which it helped to usher in. 1 Even before this, Geoffrey Elton considered history as profession and craft to be threatened by 'relativists', who favoured 'the opinion that it is all simply in the historian's mind and becomes whatever he likes to make of it'. 2 He was referring above all to E.H.
