Silvia Niccolai’s book reveals a fertile and original thinking about the delicate balance between change and permanence of the constitution. It provides food for critical thought on the current scenario of constitutional doctrine and on the unfortunately widespread understanding of change as a legal technique responding to constantly changing social needs. In the face of this technicalization of constitutional change, the rejection of an artificial and therefore inhuman idea of law and the constitution is significant, because it is aimed at avoiding the loss the autonomy and non-arbitrariness of the law itself.
