Focusing on the Working Men's College (WMC), this study charts the chequered fortunes of a Victorian project: providing workers with a "liberal education." The paper analyses the project's aim (making "better citizens"), its disciplinary content (the humanities and/or the sciences) and its challenges (the increasing prestige of vocational studies). It argues that, in an increasingly professionalised society, a "liberal education" for workers became contentious ground. As the role of the sciences within a "liberal education" diminished, and the provision of practical skills took precedence in the local-authority-funded courses, Victorian workers' opportunities for education became polarised between "useful" sciences and "profitless" humanities. With natural scientists losing the intellectual independence of their discipline to technicians, the WMC Edwardian educators chose to side unequivocally with the humanities. The paper contends that it was in the Edwardian context of the adult education movement that the "two cultures" debate first emerged in Britain.
