Analyzes the relation between the concept of “natural law” (jus naturale) and the relatively new concept of “bioethics” for law csience. The introduction of the concept of “neo jus naturale”, which is understood as a new stage in the evolution of jus naturale and the basis for the formation of an updated type of legal thinking – bioethical, is grounded in the scientific revolution. Neo Jus naturale is considered as the foundation of modern lawmaking. The dominance of positivism in postmodern law and the dominant concept of anthropocentrism in the life of modern civilization put humanity on the brink of self-destruction. However, it is still possible to delay the self-destruction of man. To do this, it is necessary to change the dominant anthropocentric worldview to progressive eccentricity and return jus naturale to the legislative process. The purpose of the study is to find out the essence of natural law, to formalize its features for practical application and to relate it to bioethics. In the process of research jus naturale is defined as bioethics. The leading methods of research are the method of “tragic dialectics” and idealistic dialectics. In general, the three-tier system of methodology (fundamental, general scientific and specific scientific methods) is applied. The application of bioethical principles at the legislative level will allow to create a high quality, legal, fair law. Such a law, that will reflect the existing needs of society, satisfy them with modern means and thus be in line with the incarnation of higher justice. Neo jus naturale the bioethical right of the future. Compliance with this law will facilitate growth of a new generation of people, improve their quality of life and, accordingly, the quality of the environment, and thus prolong the existence of human civilization
