The scope of Lewin's explorations has been very wide, dealing with a panorama of social classes and groups, with the lower depths of society as well as the bosses, with informal social norms as well as formal law, with popular religion as well as established ideology. The range of his intellectual debts is also broad, owing as much to Weber as to Marx, emphasising as much the power of ideologies and myths in human behaviour as the weight of economic structure. The key thing is the perception of society as a socio-cultural whole, though Lewin always remained open to new pathways that might appear in the course of research, always eclectic in the best sense, always eschewing the pursuit of a grand theory for all history — a pursuit which only leads you away from the rich canvas of concrete human experience.
