This volume brings together a selection of Iain Hampsher-Monk's writings on questions of historicity and rationality in political theory, together with a substantial introduction written for the volume. There are two loci around which the work revolves - one is the relationship between history and philosophy in the analysis of key concepts such as liberty, democracy and toleration, the other is the role of reason in political science's explanations. Despite a background in PPE, the author played a major role in the 'historical', revolution in political theory. Here, his reflections on the historicity of concepts in political science are presented alongside articles dealing with the role and limitations of economic modes of rationality in social and political theorising. Unifying these themes is a commitment to an understanding of human action as conscious and essentially meaning-bearing and the case for a human science rooted in such self-understandings.
