"The deaf-mute in his first years of life looks at, turns over, feels of objects that attract him, on all sides, and approaches those that are at a distance. By this he receives, like the young child who has all his senses, sensations and sensuous ideas;[C] and from the objects themselves he apprehends a number of qualities, which he compares with one another or with the qualities of other objects, but always refers to the object which at the time attracts him. Herein he has a more correct or less correct sense-intuition of this object, according as he has observed, compared, and comprehended more or less attentively. As this object has affected him through sight and feeling, so he represents it to other persons also by characteristic signs for sight and indirectly for feeling also. He shapes or draws a copy of the object seen and felt with life and movement. For this he avails himself of the means that Nature has placed directly within human power--the control over the movement of the facial muscles, over the use of the hands, and, if necessary, of the feet also. These signs, _not obtained from any one's suggestion_, self-formed, which the deaf-mute employs directly in his representation, are, as it were, the given outline of the image which he has found, and they stand therefore in the closest relation to the inner constitution of the individual that makes the representation. "But we find not only that the individual senses of the deaf-mute, his own observation and apprehension, are formative factors in the occurrences of sensation and perception, as is of course the case, but that the qualities of the objects observed by him, and associated, according to his individual tendencies, are also raised by him, through comparison, separation, grouping--through his own act, therefore--to general ideas, concepts, although as yet imperfect ones, and they are named and recognized again by peculiar signs intelligible to himself.
