“We have in ourselves tendencies that are not good and which flourish like weeds in a field. (Original sin). These tendencies are many; they fall into seven groups, known of old as the Seven deadly sins. All deadly sins tend to separate us from the child; for the child compared to us, is not only purer but has mysterious qualities, which we adults as a rule cannot perceive, but in which we must believe with faith, for Jesus spoke to them so clearly and insistently that all the Evangelists recorded His words: Unless ye be converted and become as little children, ye shall nor enter into the Kingdom of Heaven.”

That which the educator must seek is to be able to see the child as Jesus saw him. It is with this endeavour, thus defined and delimited, that we wish to deal.
