I prefer the comment of Albert Einstein who remarked, when told that he was encroaching on the divine with his investigations into the realm of time and space, ''There is no limit to what man can accomplish if he will only quit believing in God. Our government, he said, is invading the province of God, and God will be angry and punish the nation. Teach kids only things you know are good for them and don't let them have or develop any knowledge of evil. Above all, don't let them learn anything you don't already know and approve of. It is most certainly the case that what is good for children is often a matter of opinion.
Some parents think nudity is a definite evil and keep their children from it.
Other parents think knowledge of sexual matters is natural, that nudity is healthy so that their children grow up knowing and respecting the human body. The latter believe that frankness and openness are better than prudery and misinformation, and I agree. In school terms some people think that learning a foreign language cements the knowledge of one's native tongue and makes for a wider awareness, a more flexible attitude, and better international relations. Teen years are times when hormones kick in, and experimentation and curiosity replace blind trust. Plato's definition is naive at best, suicidal when applied to an educational system.
