This book, written by the president of the Iuris Naturalis Societas, compiles, updates, and reconstructs as a whole my academic efforts (2011-2024) to delve deeper into human dignity and its main ethical and legal consequences from a natural law perspective in the Aristotelian tradition, but in respectful and profound dialogue with other contemporary legal-philosophical traditions of particular importance, specifically with constructivist non-positivism (Atienza, Alexy, and Nussbaum), legal positivism (Waldron and Moreso), and critical legal studies (Fineman). This dialogue precisely marks the logical structure of the book in its five parts and nine chapters. In any case, beyond labels and affiliations, this work seeks to be an opportunity to show that, in the midst of the debate between constructivist non-positivism and legal positivism on dignity and its ethical-legal consequences, natural law in the Aristotelian tradition can also be conceived as a happy medium between two extremes, a proposal that offers essential contributions if we want to argue that, if we take human dignity seriously, not every right is available or merely conventional, and that this is compatible with the most rigorous respect for legality and authoritative institutions.
