This is not a conventional book about law. At a time when legal systems are being transformed by technological disruption, global crises, and new forms of power, the author invites readers to look beyond regulations and legal categories to rediscover the deeper essence of ius itself. The book unfolds as a dialogue between Pierre, an experienced lawyer, and Simon, a young legal intern struggling with disillusionment. Their encounter sparks a reflection on the challenges facing contemporary jurists and the fast-changing world around them. Moving beyond traditional legal analysis, the author explores both professional and human questions: how to resist cynicism, preserve intellectual integrity, and remain open to wonder. Written in an accessible yet intellectually rigorous style, this work blends legal reasoning, philosophy, and personal reflection, inviting legal professionals and general readers alike to rethink the foundations and purpose of legal thought in contemporary society.
