=Mistakes of the past.=--In the past all faithful parents have loved their children as much as we have loved our children. They were as much interested in safeguarding the virtue of their children as are the parents of to-day. They endeavored to train their children in harmony with their ideals of right. Our parents, in their childhood, got the idea that all language and information concerning sex was essentially impure. All their information was received from vicious, ignorant sources. In matured life, they came to see that all the words and language they had heard pertaining to sex and all the mental and moral impressions they had received, had done them great harm. Their experience led them unwisely to conclude that all information of this kind is injurious to a child. They failed to see the difference between receiving only half-truths, expressed in vulgar words and phrases, taught by the vicious and ignorant; and in receiving the pure truth, in chaste language from the lips of a wise teacher, a noble father or a pure mother. A nugget of gold may be pure gold, whether found in a mud hole, a slop bucket, a tar bucket, or a clear stream of water. But, if you come in contact with the surroundings of the gold, your remaining clean, becoming cleaner, or becoming soiled, will depend on the place where you find the gold. The effects, good or bad, of sex knowledge, upon a child are largely determined by where and how he gets his information. If he gets this information from a careful and wise teacher no harm can come from it. If he gets the information from the misinformed and the impure, only harm will follow.
