  According to William, the immortality of the human soul would be evident if not for the fact that the soul has, as it were, been put to sleep by the corruption of the body stemming from the punishment for sin. In our current state, however, William thinks the human soul's immortality can be shown by means of philosophical arguments, to which he devotes considerable attention, both in On the Soul and in a shorter work, On the Immortality of the Soul.
