Philosophy is the attempt to answer particular questions using transparent and convincing argument. Fundamental philosophical questions are questions about our understanding of the world in general and our place in it. As a matter of principle, these questions can only be answered through controversy. The series Basic Topics in Philosophy aims to provide a space for the discussion of such fundamental philosophical questions. Instead of providing a comprehensive introductory presentation, each volume will take issue with selected historical positions in order to analyse the particular problem and discuss possible solutions. At the same time, the authors will set their own marks and take up positions, so that the result will not be merely a view of the history of philosophy, but also a systematic contribution to the problem under discussion. The volumes in the series are intended equally for students of philosophy and other subjects and for professional philosophers. In addition, the series is aimed at all those readers with an interest in fundamental questions of philosophy.

Diagrams are not static figures, but they are rather, and in a double sense, dynamic configurations: firstly, through the interrelations they construct between the pieces of information which they provide, and secondly through the sequential ordering of several diagrams within any given textual or iconic work. That is to say, they present a rhythm or, to be even more precise, they create a visual rhythm which in turn refers to cosmic, biological, musical, ritual or social rhythms. Taking as its starting point the modern conceptualisation of social rhythms, this publication deepens our theoretical grasp of the concept of rhythm in the Middle Ages. In doing so, its aim is to enrich our understanding of diagrams and of their function in medieval culture.
