The place where streams seek ground. Towards a new territorial governmentality: the meaning and usage of the concept of territorial cohesion in the European Union

For laymen:
In the European Union they use a concept called 'territorial cohesion' ... This book shows that experts do not know what it means either.

For experts:
In the Treaty of Lisbon 'territorial cohesion' is stated as a cohesion objective of the European Union, researchers in the 'planning community' conduct research on territorial cohesion, and some even say that territorial cohesion policy is a form of spatial planning. However, it is not clear what 'territorial cohesion' means, what European spatial planning is about, and what should be done with both in government.
In a search for meaning, the research that led to his book undertook a Foucaultian fieldwork in philosophy guided by three broad and fundamental questions: i) what are the concept's meanings and knowledges, ii) how is it used, iii) and how do these sides relate? The concrete study of rationality and power construction resulted in a discourse analytical output that is meant to entice value-rational deliberation and action in social and spatial science.
