This article is devoted to a comprehensive analysis of the axiological foundations of modern law in the context of the challenges of technological development. The relevance of this research stems from the need to find moral guidelines for resolving new ethical and legal dilemmas in the fields of biomedicine, artificial intelligence, and ecology, which cannot be adequately understood within a purely positivist approach. The aim of the work is to identify and systematically analyze the key philosophical paradigms that form the axiological foundation of legal systems and to assess their heuristic potential. The research methodology includes a historical and philosophical reconstruction of the genesis of axiology as a discipline (from Aristotle to the Neo-Kantians) and a comparative analysis of three main ethical and axiological theories: virtue ethics, deontology, and consequentialism. It was established that each paradigm makes a unique contribution to understanding the value-based nature of law, but their synthesis and critical dialogue are necessary for the development of a holistic legal worldview. The main conclusion of the study is that the legitimacy and moral authority of law directly depend on the reflexive assimilation and hierarchization of values, while ignoring the axiological dimension leads to legal relativism and the loss of law's educational and culture-forming function.
