In Amphitryon 38, Giraudoux, one of the best dramatic authors of the French theatre, wanted to pread out, through its principal heroin, Alcmene, the problem of the human free will confronted with the prescience and divine omnipotence. The fact that Alcmene, satisfies with its humanity until refusing offered of the immortal Jupiter divinity, even in the most dramatic circumstances where all is arranged, generated and limited by the god of the gods, its humanity defends is an extremely remarkable turning of the author who clearly exposes his desire of bringing together of divine to the human one. Initially, while exposing to the god of the gods a mortal satisfied with her destiny, heroin is finally able to make it accept the dignity of humanity. One noted there the possibility of harmonious cohabitation between these two large components of Cosmos: the man and God, not only thanks to the friendly gift of Alcmene, but also by the obstinacy of this one, the characteristic of the divinity. However, it was noted that the human being is limited and weak in front of the laws of the universe which was built since and which is built perpetually. Even if it builds its domestic equilibrium, it is impossible for him to arrange all the remainder of the universe and to change the course of the needs for the universal determinism and to avoid fates since it acts of an inevitable predestination for the human one like for the divine one.
