This chapter introduces the proposed theoretical toolbox this book intends to use for the studying of democracy in Europe. The idea is that the analytical concepts created by this toolbox will prove useful for understanding the various aspects of democratic politics seen throughout Europe. The fundamental philosophy of this book is the idea that to understand democratic governance, in particular in Europe, there needs to be a model. The goal isn’t to include every single possible detail of what is observed in the real world. Rather, it is to consider the essential elements for understanding democratic politics and to use those to highlight the various nuances found in the real world. A model is a comparative and analytical tool, rather than a method of example.
