The Confessions And Letters Of St by St. Augustine
Chapter VIII.--That When a Boy He Learned to Speak, Not by Any Set Method, But from the Acts and Words of His Parents.
13. Did I not, then, growing out of the state of infancy, come to boyhood, or rather did it not come to me, and succeed to infancy? Nor did my infancy depart (for whither went it?); and yet it did no longer abide, for I was no longer an infant that could not speak, but a chattering boy. I remember this, and I afterwards observed how I first learned to speak, for my elders did not teach me words in any set method, as they did letters afterwards; but myself, when I was unable to say all I wished and to whomsoever I desired, by means of the whimperings and broken utterances and various motions of my limbs, which I used to enforce my wishes, repeated the sounds in my memory by the mind, O my God, which Thou gavest me. When they called anything by name, and moved the body towards it while they spoke, I saw and gathered that the thing they wished to point out was called by the name they then uttered; and that they did mean this was made plain by the motion of the body, even by the natural language of all nations expressed by the countenance, glance of the eye, movement of other members, and by the sound of the voice indicating the affections of the mind, as it seeks, possesses, rejects, or avoids. So it was that by frequently hearing words, in duly placed sentences, I gradually gathered what things they were the signs of; and having formed my mouth to the utterance of these signs, I thereby expressed my will. Thus I exchanged with those about me the signs by which we express our wishes, and advanced deeper into the stormy fellowship of human life, depending the while on the authority of parents, and the beck of elders.
