The following passage in Reid's Inquiry provides a key for the understanding of his difficulty in conceiving an adequate picture of man's being. In this passage Reid maintains that all art is based on man's experience of the natural language of things, and that in every human being there lives an inborn artist who is more or less crippled by man's growing accustomed to the state of artificial language in his intercourse with the world. In continuation of the passage quoted on page 99 Reid says:
'It were easy to show, that the fine arts of the musician, the painter, the actor, and the orator, so far as they are expressive; although the knowledge of them requires in us a delicate taste, a nice judgment, and much study and practice; yet they are nothing else but the language of nature, which we brought into the world with us, but have unlearned by disuse and so find the greatest difficulty in recovering it.
'Abolish the use of articulate sounds and writing among mankind for a century, and every man would be a painter, an actor, and an orator. We mean not to affirm that such an expedient is practicable; or if it were, that the advantage would counterbalance the loss; but that, as men are led by nature and necessity to converse together they will use every means in their power to make themselves understood; and where they cannot do this by artificial signs, they will do it as far as possible by natural ones: and he that understands perfectly the use of natural signs, must be the best judge in all expressive arts.'
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
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.
