唯一值得被称为自由的自由是追求我们自己的幸福，以我们自己的方式，只要我们不试图剥夺他人的自由，或妨碍他们争取幸福的努力。
The only freedom which deserves the name is that of pursuing our own good in our own way， so long as we do not attempt to deprive others of theirs， or impede their efforts to obtain it.
The self grows through dialogue with others and with the world.
释义：圆的器物容易滚动，而方的器物则易于停止，这是器物的差异；金属刚硬而水则柔弱，这是它们的物性不同。
