Here is the proper place for the injunction, not to argue with children. “I cannot be too emphatic and outspoken in my warning against too much arguing,” says Caroline Rudolphi; and Schwarz, who quotes this passage, adds, “Once is too often.” Niemeyer, after speaking of the excesses of abnormal liveliness and characterizing thoughtlessness, which, he says, “causes inattention, a disregard for consequences, and hasty actions,” continues thus: “All these are not faults of the heart; still they are faults that need to be amended, and about the only sure educational method for amending them is to cultivate right habits. Positive punishments wisely chosen may indeed be employed as auxiliary means, but only when there are evidences of a lack of good intention, or when these faults have become ominously prominent.” He further advises teachers to insist on this, that pupils rectify on the spot what can be rectified, since vague recollections prove barren of good results. This does not, of course, dispose of the whole matter, but we are still discussing training as a supporting agency, and from this point of view it is true that argument should not be substituted for the cultivation of habits. 165. To restrain the lively but thoughtless boy is more difficult than to keep him properly active, for the latter is comparatively easy, in some cases at least, if instruction excites his interest. The reverse holds true for the sluggish boy because an attack has to be made on his indolence. Here the stimulation to physical exertion through association with wide-awake playmates is the first thing to be secured; and where hard lessons cannot as yet be managed successfully, lighter occupations will have to suffice. Where sluggishness is traceable to bodily feebleness, improvement may be hoped for from sanitary measures and increasing years. The following rule is to be observed everywhere: No exercise must exceed the pupil’s strength, but that which has once been begun must be completed. At the least, pupils must not be allowed to drop their work as they choose; they must look upon it as a whole, however small.
