In this essay, translated into Spanish for the first time, Jean-Luc Marion, unarguably the leading figure of the younger generation of philosophers working in France today, elaborates a non -ontological interpretation of Saint Anselm's argument on the existence of God. But Marion's interpretation is more than a mere critique of the tradition that, since Kant, has dominated the understanding of Anselm's argument. Rather, he establishes the clues for a phenomenological thinking beyond the tradition which Heidegger called onto-theology, the clues thus that anticipate Marion's controversial phenomenology of "givenness" controversial due to its unmistakably theological appeal.
