On the education of children depends the future of nations. To consider the education of children is to prepare for future generations. The heart of the child is like a photographic plate without any impressions on it, ready to reflect all that it is exposed to. All the good qualities which help to fulfil the purpose of life are the natural inheritance that every soul brings to the earth; and almost all the bad traits that mankind shows in its nature are as a rule acquired after birth. This shows that goodness is natural and badness unnatural. Therefore the child who has not yet had the opportunity of acquiring bad traits in life can, if helped, develop the natural goodness that is in its soul.
