This is because at that point, one will have the necessary facts to be able to arrive to such a conclusion. This means that happiness is a final objective in itself, a quest by individuals who try to be happy all the way to their death, including in the way they pass away and the way they live their lives. Throughout life, Aristotle points out, one can only say that he is fortunate rather than happy, which is a conclusion that can be drawn only at the very end. On the other hand, a rational being contemplates its existence and path to happiness. Its contemplation is part of the final happiness at the end of one's life.

4. The first thing worth pointing out is that Augustine's conversion is followed by his dedication of his life to the intellectual and spiritual conversion and enlightenment of other individuals. This means that the focus shifts from his own personality to the personalities of the individuals around him. His approach tends to move from the simplified to the complex and encompass the debates, doubts and questions that individuals have and that he himself may have encountered before his...

With his approach, he wants other individual to follow on his footsteps in becoming enlightened.
5. Aquina's five ways are formed of arguments from motion, efficient causes, possibility and necessity, gradation of being and design. Each way provides a series of rational steps, drawing to recurrent conclusions which are then used in the subsequent steps of the ways. Some of this assertion are very vague and general, such as the arguments that form the fifth way, the argument from design. To assert that "most natural things lack knowledge" is at least general, not to mention that it can also be considered as untrue.

In my personal opinion, the existence of God is not something that can be proven rationally, as Aquinas suggests. For each one of his arguments, rational arguments against the existence of God, from the same category, can be easily discovered and used. Believing in God's existence can only be an exercise of assumed faith by which the believer renounces his rationality in order to embrace the irrationality of faith and accept the existence of God.
