When Reid says that there are certain characteristics - and these just of the kind whose development truly ennobles human life - which the soul brings with it into the world, a picture of man is evoked in us in which the supersensible part of his being appears as an entity whose existence reaches further back than the moment of birth and even the first beginnings of the body. Now such a conception of man is in no way foreign to humanity, in more ancient times it was universally prevalent, and it still lives on to-day, if merely traditionally, in the eastern part of the world. It is only in the West that from a certain period it ceased to be held. This was the result of a change which entered into human memory in historical times, just as the re-dawning of the old knowledge of man's pre-existence, of which Reid is a symptom, is a result of another corresponding alteration in the memory-powers of man in modern times. For men of old it was characteristic that alongside the impressions they received in earthly life through the senses (which in any case were far less intense than they are to-day), they remembered experiences of a purely supersensible kind, which gave them assurance that before the soul was knit together with a physical body it had existed in a cosmic state purely spiritual in nature. The moment in history when this kind of memory disappeared is that of the transition from the philosophy of Plato to that of Aristotle. Whereas Plato was convinced by clear knowledge that the soul possesses characteristics implanted in it before conception, Aristotle recognized a bodiless state of the soul only in the life after death. For him the beginning of the soul's existence was identical with that of the body. The picture of man, taught for the first time by Aristotle, still required about twice four hundred years - from the fourth pre-Christian to the fourth post-Christian century - before it became so far the common possession of men that the Church Father Augustine (354-430) could base his teaching on it - a teaching which moulded man's outlook on himself for the coming centuries right up to our own time. The following passage from Augustine's Confessions shows clearly how he was compelled to think about the nature of the little child: 'This age, whereof I have no remembrance, which I take on others' words, and guess from other infants that I have passed, true though the guess be, I am yet loath to count in this life of mine which I live in this world. For no less than that which I lived in my mother's womb, is it hid from me in the shadows of forgetfulness. But if I was shapen in iniquity and in sin my mother did conceive me, where, I beseech thee, O my God, where, Lord, or when, was I thy servant guiltless? But lo! that period I pass by; and what have I to do with that of which I can recall no vestige?'4
