=How did I get into this world?=--At the age of three, four and five the child will begin to ask questions as, “Where does the rain come from? Where does the snow come from? Where do the clouds come from?” When kittens, pups, pigs, a calf, a colt are born, the child very naturally asks about their origin. The child is told repeatedly that he is four, five or six years old; that he has had that number of birthdays and has seen that number of Christmases. He remembers only half of them. He listens with interest to his parents as they relate some thrilling event of years gone by. A bright inquiring child will naturally ask, “Mamma, was I in the world at that time?” The mamma replies, “No, darling, that happened six months before you were born.” How very natural it was for the child to ask, “Well, mamma, where was I at that time? How did I get into the world?” An angel could not be more sincere, or ask a purer question. This was no evidence of the child’s depravity. When I find a child of seven or eight years old who has not asked about his origin, I know that one of three conditions will explain this unusual mental state of the child. (1) The parents have not encouraged the child’s mental development by permitting him to be free in asking questions. (2) The child has heard the story of life told by vicious companions, in half truths, clothed in vulgar language and is keeping his information a secret from his parents. (3) The child is not developing quite as fast as I would like for my child to develop. =The unsatisfied mind.=--When the inquiring mind of a child has once become interested in this question, it is not possible for him to be satisfied until a plausible answer has been received. The child’s future, physical, mental and moral life more largely depends upon the answer given to this question, than to any other question of his childhood. =The most vital part of a child’s education neglected.=--In the past, parents, teachers, reformers and ministers have very largely held to the old theory, that, if children are to be kept pure and innocent, they must be kept ignorant of all information pertaining to sex. We have them learn the physiology, anatomy and hygiene of their brain, heart, lungs, digestive and nervous systems as if their very lives depended upon a correct knowledge of these parts; but we have allowed them to grow up in total ignorance concerning the sacred sanctuary and function of human reproduction, upon which so much of health, happiness and success in life depends.
