St. Augustine's understanding of time is such that it makes time a problem not of physics nor of cosmology, although there are cosmological implications too, but of moral philosophy. And since moral philosophy, for Augustine, is inseparable from the problem of the ultimate destiny of the soul, his conception of time is a part of his conception of the religious life of man. Accordingly, I propose to summarize Augustine's theory of the nature of time in the first part of the (...) paper, treating it, so far as possible, as a separate topic of a theoretical nature. However, since the whole problem is a practical one in the Platonic sense, I propose, in the second part of the paper, to interpret this theory in Augustinian terms in an effort to show the significance of the whole question of time and eternity and limited being for Augustine's theory of man. This is an immense subject. Consequently, in order to impose some boundary upon it, I have restricted myself to the contrast of "the Unlimited" and "the Limited," "the Unchangeable" and "the Changeable" as a means of giving the interpretation a single accent.
