Almost everyone agrees that the ability to read and write should be a fundamental human right, extended to everyone. We understand that a person who cannot read is in thrall to (受…控制，影响) those who can. You cannot enter the developed world as a full human subject unless you can break and master the code of the word. Today, literacy doesn't stop with words and numbers. To enter social and political debates as a full participant, one must also break the thrall of the magic box and master its secrets.
