Silence is the language of the oppressed.

透明度建立信任。从农民到消费者，每个利益相关者都该知道食物如何抵达餐桌。

Surround yourself with people who challenge you, not just agree with you.

The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

Always keep your knife sharp, your wits sharper, and your spirit sharpest.

Train people well enough so they can leave, treat them well enough so they don't want to.

伟大的哲学家是那些有勇气为自己思考的人。
