My dear,

Be careful of books. Be careful with books. Be careful or one can become a weapon-wielder. Be careful or one can become the victim.

Be careful or one can become a pirate from an age in which they roamed, or a ninja from a clan hidden in the deepest of jungles, or a boy trying to be a man by exploring the jungles forbidden, or a girl trying to make it in the big city.

But most of all, be careful of books unread. For they make the most victims. For they contain knowledge that readers use against the unread, both intentionally and unintentionally.

Be careful of books. Be careful with books. Be careful or one can become a weapon-wielder. Be careful or one can become the victim.

Falsely yours,
Cai Guo-Qiang
