The majority of the philosophical proves of the existence of God or other philosophical attempts of talking about Him try to meet standards of rationality only. In this way they reach mostly a philosophical notion of God which rules out a religious relationship to Him. Zubiri is trying to present a philosophical way which leads to a notion of God, who can be at the same time a God of philosophy and of religion. But this means overcoming rationality with reasonableness. Reasonable means compatible with human life.
