"Children should be educated and instructed in the principle

John Adams is US president,Americans fall in love with freedom,it is claimd in their Constitution.So we could understan why Adams say this.
Whether is this true?What is freedom?What we need in our study when we are children?That needs you to think .
In my opinion,when we know what we should study then we could study with freedom,but when we don't know we must be fully educated without feedom.
In another way,out method of study could be in the principles of freedom too.
Hope it's useful for you!
