On the grounds of such experience, Augustine was unable to picture man's being in any other way than by seeing him, from the first moment of his life, as subject to the condition of the human race which resulted from the Fall. Thus he exclaims in his Confessions: 'Before Thee, O God, no-one is free from sin, not even the child which has lived but a single day on the earth.' In so far as there was any question of the soul's arising from this fallen state, it was deemed unable to attain this by any effort of its own, but to depend on the gifts of grace which the Church was able to dispense through the Sacraments. Compare with this the present-day scientific conception of human nature, as it dominates the thought of specialist and layman alike. Here man appears, both in body and soul, as a sum of inherited characteristics, of characteristics, that is to say, which have been passed on by way of sexual propagation and gradually emerge into full manifestation as the individual grows up. Apart from this inherited predestination the soul is held to present itself, in Locke's classical phrase, as a tabula rasa upon which are stamped all manner of external impressions. The similarity between this modern picture of man and the earlier theological one is striking. In both cases the central assumption is that human development from child to man consists in the unfolding of certain inherited characteristics which are capable of further specific modification under influences proceeding from outside. The only difference between the two pictures is that in the modern one the concepts of heredity and adaptation have been formed without special application to the ethical characteristics of the soul. It is clear that from both Augustine's and the modern scientific viewpoint there is no sense in requiring - as Reid did - those who seek the truth about themselves and the world to recover a condition which had been theirs as children. Nor from this point of view is there any justification to call on a Common Sense, innate in man, to sit in judgment on the philosophical efforts of the adult reason. * That even in the days of Augustine the original conception of human nature had not disappeared entirely, is shown by the appearance of Augustine's opponent Pelagius, called the 'arch-heretic'. To consider him at this point in our discussion will prove helpful for our understanding of Reid's historic position in the modern age. What interests us here in Pelagius's doctrine (leaving aside all questions concerning the meaning of the Sacraments, etc.), is the picture of man which must have lived in him for him to teach as he did.
