This book...filled me with admiration. It is so typical of certain features of Nino's character, especially his intellectual curiosity and his modesty. Nino, himself a great master of international law, felt the need to interview five masters of international law. It is also highly significant that he emphasizes and praises the human qualities of the interviewees, which were also his own, such as simplicity, affability, gentleness, urbanity, esprit de finesse and witty irony.Each interview makes for lively and interesting reading: one grasps the rich and different personalities of the interviewees...In spite and beyond their differences, they present important common features. All of them embraced legal positivism, though to varying degrees.
