Long, o my Son, hath been this Digression from the plain Path of my Word concerning Children; but it was most needful that thou shouldst understand the Limits of true Liberty. For that is not the Will of any Man which ultimateth in his own Ruin and that of all his Fellows; and that is not Liberty whose Exercise bringeth him to Bondage. Thou mayst therefore assume that it is always an essential Part of the Will of any Child to grow to Manhood or to Womanhood in Health, and his Guardians may therefore prevent him from ignorantly acting in Opposition thereunto, Care being always taken to remove the Cause of the Error, namely, Ignorance, as aforesaid. Thou mayst also assume that it is Part of the Child's Will to train every Function of the Mind; and the Guardians may therefore combat the inertia which hinders its Development. Yet here is much Caution necessary, and it is better to work by exciting and satisfying any natural Curiosity than by forcing Application to set Tasks, however obvious this Necessity may appear.
