This paper argues that in Book XI of the Confessions, a song is not only an image of the divine unity of time on which our own unity of soul is based. Augustine is thinking of creation through the song as divine revelation. Thus through a kind of grace he brings out the unity of time and eternity, of knowledge and image, of thinking with its object, and ultimately of God's creation with the very act of confession. What he is (...) doing and what he is understanding are thus becoming one. (shrink)
