把这一句，留给此刻的你

With paper printed books, you have certain freedoms. You can acquire the book anonymously by paying cash, which is the way I always buy books. I never use a credit card. I don't identify to any database when I buy books. Amazon takes away that freedom.

有了纸质书，你就有了一定的自由。你可以用现金匿名购买这本书，这是我经常买书的方式。我从不使用信用卡。当我买书的时候，我不认同任何数据库。亚马逊夺走了这种自由。
