Genesis of the rational «proof» for the existence of God in Xavier Zubiri in light of his last writings

This paper attempts to show how Zubiri was understanding and explaining his «proof» or argument for the existence of God from his last works. We study his proof through the «way of religation» from four texts or seminars: The theological problem of man: God, religion, Christianity (1971), The unfolding of the problem of God (1971-1973, published as a second part in Man and God), The theological problem of man: man and God (1973) and Sentient Intelligence (1980-1983).
