This work is based upon philosophy of st. Thomas Aquinas and his view and the view of his interpretors about nature, supernature, and grace. In this paper I will try to, through a historical review, set out the main versions of the interpretations and their main proponetns. Human beings naturally desire beatitude. Beggining with Aristotle and Plato, philosophers have sought to articulate both the nature of beatitude and how it is that the man both knows and desires this beatitude (happiness). In the thomistic tradition there are two main schools of thaught about this subject. One school says that the human being naturally possesses an innate desire for the vision of God. That is, every human being wants to go to heaven in order to see God as He is. The other school of thaught teaches that the human appetite the seeing the essence of God is elicited by God directly without any mediation or by knowledge of the existence of God. The debate comes down to weather human desire for his beatitude is innate or weather it is elicited. In this paper I will try to explain both positions and show the solutions to the problem witch are offered by the authors.
