Mark Selzer has a fascinating excursion into Augustine’s understanding of time here. Augustine derived an understanding of time that is largely supported seventeen centuries later by physics.

“In Book XI, of his Confessions, Augustine inquires into the nature of the human experience of time, or phenomenological time. Augustine arrives at revolutionary conclusions on the nature of phenomenological time in the course of his inquiry . . . We are pulled into the past by our memories and extended into the future by our expectations, which thereby distracts us from the reality of the eternal present that is, most fundamentally, our experience of time. As concluded earlier, the divine eternity is “a never-ending present.”
