But there is only one thing which gathers people into seditious commotion, and that is oppression.

智者知道如何拥有，而不仅仅知道如何获得。

Every child should have mud pies, grasshoppers, water bugs, tadpoles, frogs, mud turtles, elderberries, wild strawberries, acorns, chestnuts, trees to climb, brooks to wade in, water lilies, woodchucks, bats, bees, butterflies, various animals to pet, hayfields, pine-cones, rocks to roll, sand, snakes, huckleberries and hornets; and any child who has been deprived of these has been deprived of the best part of education.

The urban tribe is overrated.

"知道"的含义已经从能够记住和重复信息转变为能够找到并使用信息。
