La legge della fiducia by Tommaso Greco is not just a good book: it is an important book. Its well-deserved success clearly testifies such a relevance. In my comment, however, I propose a reading of trust in terms of a gift, and not of a law. Crucially, taking up the work done by Jacques Derrida on his essay devoted to Marcel Mauss’s analysis of gift, I will attempt to show how trust can be interpreted as a pure – and not only as a ceremonial – gift.
