[Bioethics through a philosophical lens: the (bio)ontological foundations of Juliana González Valenzuela's proposal].

The enrichment of bioethical proposals built from and for Latin America has been increasing in recent decades. In order to contribute to this, our objective is to present a proposal for a bioethical interpretation from a philosophical approach based on the identification of central concepts of Mexican philosopher Juliana González Valenzuela. A dual bio-ontological foundation was identified: a) the "dialectic phenomenology of life," which allows the synthesis between the biological and cultural aspects of human beings, as well as the overcoming of its contradictions; and b) the Homo humanus, which enables the existence of the bio-ethical being affirmed as an authentic being and one who seeks a good life (eu-bios and eu-zoein). Reflection on and critique of the implications that the bio-ontological foundation hypothetically couples to law and power led us to identify main arguments. However, the necessary link between the bio-ethical being and said disciplines was evidenced by virtue of their social and communitarian nature (zoon politikón, ζῷον πολῑτῐκόν).
