"There is not a page [St. Augustine] has written on which his powerful personality, not to say his temperament, does not reveal itself. In both the eulogistic and dyslogistic senses of the word, Augustine is a man of desires. From infancy and throughout his whole life he sought happiness and even absolute happiness - that is to say, beatitude, the possession of a perfect good that was beyond all fear of loss. Two means were required for the acquisition of this end: love, which is nothing less than the very movement of the soul towards the Good, and knowledge, since the supreme Good, being Truth, cannot fill the soul of man with joy except by fully revealing itself to his intellect." - Étienne Gilson, The Idea of Philosophy in St. Augustine and in St. Thomas Aquinas
