This invitation to federalism stems from the belief that the nationalities question has to be raised in Spain not only legal and political criteria but above all "in the field of human warmth," as rightly said that socialist who was Anselmo Carretero from his Mexican exile. Based on this assumption worth 'living together', the arguments in this book point to a plurinational federal state, which in Spain is as important as urgent arrive.

The picture of the Spanish reality can not simply neocentralistas strokes painting on the one hand, and independence on the other. It needs to make the voice of federalism, pushing through these conflicting dynamics, with its proposal for the re-articulation of the Spanish State. A federal political pact must accompany the constitutional reform appears as necessary. The complexity of the Spanish state claims will make possible, reforming the autonomous State, its future as a federal state in which the solidarity redistribution of burdens and benefits and recognition of legitimate differences can be achieved effectively and fairly.

In Spain to form a multinational federal state is necessary that the public debate is open to the demystification of sovereignty and rethinking representing the plurality of nations for their legal and political reality. Similarly, in addition to conceptual clarification, political courage is required to undertake all matters concerning the right to decide on the legitimacy of democratic processes and legal framework in which our social life has developed. Speaking of all this is to promote the social, cooperative federalism and pluralist democratic coexistence project.
