How, then, can it be estimated? Indirectly, by the evidence of others.
The inspector, then, must be content to accept the facts which are given to him by the teacher, but he must not accept them altogether on trust. Are these facts correct? Are they probable? Is any evidence of them to be found? Have they been altered in the telling? Such will be the first queries to awaken the critical spirit of the inspector. Then it must not be forgotten that he can question the parents, and hear their replies before letting them know the opinion of the teacher, and that everything they say will help him to judge not only the child, but the family circumstances in which he lives. The ill-balanced are often spoiled, or only children, or children not looked after, or children whose father has disappeared. The sons of widows form a considerable contingent. Now, the inspector will gain a good deal of information from the school history of the child. The ill-balanced is a nomad. He has attended several schools. It is important to find out what impression he has left behind him. The proof of want of balance is not to be taken from a single teacher. If three teachers, at least, whose pedagogic reputation is good, agree about a child, the chances are that their estimate is correct. The inspector will resort to such controls, and if he is not satisfied, and if the alleged facts are not very serious, he will remove the child to another class or another school rather than send him to a class for defectives.
Elimination of Hospital or Asylum Cases.—Only defectives likely to improve are to be admitted to the special schools. That is only common sense. Everyone knows that the epithet "defective" does not belong to a single type. There are various categories which extend between two extremes: the purely vegetative idiot who cannot speak, or walk, or even feed himself; and the slightly feeble-minded, who may easily be taken for normal. In spite of all our sympathy for these poor creatures whom Nature has treated so cruelly, we could not think of supplying them without distinction with all the benefits of education. It is certain that the worst affected would not profit much thereby. It is pure folly to devote six or eight years to teaching the letters to a child who will never be able to read, or who, if he should manage to read a little, will not understand what he reads. To such an unfortunate it is quite enough to give lessons in walking, feeding, dressing himself, and in simple occupations, such as dusting or sweeping. Such cases do not require schools so much as places where they can be taken care of. These will cost less to establish, especially in the country. Educational efforts should be concentrated on the defectives who are less profoundly affected. It is they alone whom one should try to instruct. This is the practice which is rightly followed abroad. For administrative purposes the defectives of different grades may be divided into two groups, medical cases and educational cases, or preferably, in order to obviate the use of the equivocal term "medical," we may speak simply of hospice cases and school cases to show the difference in their destination. The exact terms employed matter little so long as we understand what we mean by the words.
We have just pointed out the importance of reserving the schools for defectives for improvable cases. But it is necessary to correct this word "improvable," because all defectives can be improved more or less. Their asserted arrest of development is not complete, and the expression is equivocal. It would be better to replace the word "improvable" by the following more precise phrase: "Capable of being taught to gain, in part, their own living." Which of them are in this position? Unfortunately, we do not know. All such questions should have been solved long ago, since thousands of defectives have passed into the hospices. It would have been enough to have followed them up, to have found out what became of them, and to have drawn conclusions. But this has never been done methodically, and for the present we are reduced to conjecture. The nearest estimate we can form is that the social value of any individual case, not epileptic, is in inverse proportion to the degree of deficiency; the imbecile would seem to be more improvable than the idiot, and the feeble-minded than the imbecile. But this is simply hypothesis, and we accept it quite provisionally, until exact investigations have been made which will permit us to replace conjecture by demonstrated truth. Consequently we shall open wide the doors of the school to the feeble-minded and close them to the idiots, while as to the imbeciles, we shall have to find out whether the proper place for them is the school or the hospice. It will be necessary to find out in what measure, and at the price of what effort, an imbecile can be instructed to the point, say of being able to read. There are two other indications which may help us. Cases of acquired mental deficiency—that is to say, cases who have become defective as the result of something which affected them after birth—are usually less improvable than congenital cases, or cases where the deficiency is due to some cause acting before birth. And, secondly, cases affected by epilepsy, with fits or frequent attacks of vertigo, usually undergo a progressive mental deterioration.
What distinctions can we draw between the different degrees of mental deficiency? Such a question, we think, might be asked with regard to the ill-balanced as well as the defective. With respect to the former, we have no criterion at present to offer. It will be enough to pick out and send to the hospices the most ill-balanced, those whose presence among normal children would be a danger owing to the perversion of their instincts or the brutality of their impulses.
With regard to mental deficiency, we think it possible to formulate precise definitions which will enable all competent persons to agree as to the diagnosis of idiocy, imbecility, and feeble-mindedness. We are aware that in making this statement we are running counter to the general practice of medical alienists. When these, in an admission certificate, call a child "idiot," "feeble-minded," or "imbecile," they are rarely in agreement with the confrère who, a few days later, examines the same child, and makes a new diagnosis. We have made a methodical comparison between the admission certificates filled up for the same children with a few days' interval by the doctors of Sainte-Anne, Bicêtre, the Salpêtrière, and Vaucluse. We have compared several hundreds of these certificates, and we think we may say without exaggeration that they looked as if they had been drawn by chance out of a sack. This is a fact which many alienists have already suspected, and Dr. Blin[11] has expressed himself frankly on the subject.
What is the cause of such contradictions? They result, in great measure from the use of ill-defined terms. To the majority of alienists, the idiot is one who is profoundly affected in his mental faculties, the imbecile is a little less, and the feeble-minded less still. What mean those words: "profoundly," "a little less," "less still"? No one defines them. They are taken to be indefinable. It is no wonder they are understood so differently. All this trouble would disappear if the following definitions were adopted:
Definition of an Idiot.
An idiot is any child who never learns to communicate with his kind by speech—that is to say, one who can neither express his thoughts verbally nor understand the verbally expressed thoughts of others, this inability being due solely to defective intelligence, and not to any disturbance of hearing, nor to any affection of the organs of phonation. Since a normal child of two years of age can understand the speech of others, and can make itself understood by others, so far as its simple wants are concerned, it is evident that the distinction between an idiot and a normal child is easily made.
