This chapter defines the field of history by examining both the topics it investigates and some of its long-standing and unique epistemological and methodological assumptions. It points out the unique breadth of the discipline, which has always taken the whole of human experience as its object of study. It emphasizes the holism of the discipline – that is, History’s consistent interest not in particular parts or aspects of that experience, but in the interactions between different aspects of human societies. It examines the historicist tradition within the discipline – the fundamental assumption that every aspect of human life is conditioned by its broad historical context. And it explores the way in which that fundamental assumption has contributed to a primarily idiographic epistemological position – an interest in the analysis of the particular and specific, rather than the general or universal.
