To provide the necessary corrective to Augustine’s doctrine of inheritance, Pelagius would have had to be able to see in the first years of life both a beginning of the earthly and a termination of the pre-earthly existence of the soul. The imperfections of his picture of man, however, led him to underestimate, even to deny, the significance of heredity and so of original sin in human life. For an age which no longer had any direct experience of the soul’s pre-natal life, the doctrines of Augustine were undoubtedly more appropriate than those of Pelagius; Augustine was in fact the more modern of the two.
