The author has collected in this book some of the essays he has written in the last ten years, the majority of them already published. His aim is a first attempt to articulate the preliminaries for a theory of the Constitution, that is, an account of some of its philosophical foundations. These foundations come from different origins: from the juridical theory, of course, but also from the philosophy of language as well as from the social, moral and political philosophy. In this sense, the present debate about some constitutional questions is really fascinating because it demands some room where all these disciplines interbreed.

This book is divided into three parts: the first is dedicated to the background of the Constitution, the second one to the theory of law for this period of constitutionalism and the third deals with the judicial application of the Constitution. The general character of the first essay tries to intertwine the tree parts.
