This article seeks to integrate the roles of structure and human agency in a theory of historical causation, using the fall of the Weimar Republic and in particular Henry Turner's book Hitler's Thirty Days to Power as a case study. Drawing on analogies from chaos theory, it argues that crisis situations in history exhibit sensitive dependence on local conditions, which are always changing. This undermines the distinction between causes and conditions . It urges instead a distinction between empowering and constraining (...) causes of specific human actions as a more fruitful model. The paper also discusses more briefly two other analogies to chaos theory: 1) similarity across differences in scale as applicable to different levels of individual and collective events, which are seen as homologous; 2) a model of branching as applicable to the totality of causes of a given event.

In response to the unsettled state of modern intellectual history, a model is offered for categorizing its subject matter. Two challenges to intellectual history are first examined: the relation of intellectual to social history and the relation of intellectual history to other disciplines which purport to deal with thought. The model proposed breaks down the "ideas" of intellectual historians into two sorts: 1) systems, complex bodies of thought related in a coherent fashion; and 2) embodiments, a way of fixating or (...) condensing a complex of meanings into a single expression. Each entails a distinct mode of communication, the former by processes of education or socialization, the latter by single symbols or slogans. The distinction between systems and embodiments is clarified by comparison to the abstract-concrete and the discursive-mythical thought distinctions. The "ideas" of intellectual history should ideally include both systems and embodiments as their components, as in the case of the Lutheran Reformation and the French Revolution. By showing their relation to other disciplines, these distinctions can be seen to demarcate the space in which intellectual history can operate. (shrink)
