Between liberal constitutionalism and new representations of constitutionalism: when constitutional concepts are swinging

Classical concepts of constitutionalism had to adapt to new realities, new challenges, new political demands. If terminology has remained quite similar, its meaning seems to have changed, sometimes implicitly. These conceptual attempts face epistemological choices that need to be of some interest and useful for constitutional knowledge. In that way, one constitutional concept could be extended, or defined differently, in order to inspire a new way of thinking or to shape another representation of the world.
