Note A, pages 45 and 55.--It may perhaps be reasonably objected to this term of "Reiteration," that it is a new term for an act of the mind which has already received another name. The Author's excuse is two-fold. In the first place, he thinks, that any other term which he could have employed, might have been misunderstood, as writers are not as yet at one on the subject. But, secondly, no other term would have included so fully all that he intends to designate by the act of "Reiteration." In this he may be mistaken; but as it is of little consequence by what name an object may be called, provided the thing so named be properly defined, he thought it safest to apply the term he best understood, and which, in his opinion, most correctly describes the act itself. The same thing may be said of the terms, "Individuation," "Grouping," and "Classification," which may perhaps be nothing more than "Abstraction," "Combination," and "Generalization." His misconception of those latter terms, and of what is included in them, may have led him to think that the mental operations which he has perceived in the young are different. If so, there can be little harm in using the terms here adopted; but if, on the contrary, they do really include more, it would have been hurtful to use a term which had been previously defined, and which did not include the whole that was intended. Note B, p. 56.--It may be a question, but one certainly of little practical consequence, whether we ought to place the principle of "Individuation," or this of "Reiteration," first in order. The child, no doubt, fixes upon the individual object before he can reiterate it; but it is still this act of reiteration that first impresses the idea on the mind, and constitutes it a part of his knowledge. Note C, p. 58.--It may be proper here to explain once for all, that it is not the intention of the Author, as indeed he has not the ability, to define scientifically the mental processes which he thinks he has observed in the young. His object is simply to point them out, so that they may be successfully imitated by the teacher in the exercises of the school.
