This book explores a specific aspect of modern parliamentarism: its ability to produce and organise political knowledge.

The book argues that the very meaning of modern parliamentarism cannot properly be understood without considering the cognitive value which is inherent in the representative function discharged by parliaments, vis-a-vis the political community. It does so by studying the 'encyclopaedic patterns' underlying modern parliamentarism. Exploring the concept from ancient times to modernity, it addresses the fundamental question of the relationship between knowledge and democratic decision-making. This is a truly innovative book; challenging, provocative and asking crucial questions of how parliaments work and legislate.
