Life is a never-ending school, and the really important lessons all tend to teach man his proper relation to the environment where he must live.
It is bigotry for public schools to teach only one theory of origins.
If today you can take a thing like evolution and make it a crime to teach it in the public school, tomorrow you can make it a crime to teach it in the private schools, and the next year you can make it a crime to teach it to the hustings or in the church. At the next session you may ban books and newspapers. Soon you may set Catholic against Protestant and Protestant against Protestant, and try to foist your own religion upon the minds of men.
