一旦心灵被启蒙，就无法再次变得黑暗。

The tyranny of secrecy is the most tyrannical of all tyrannies.

写作是我对抗遗忘的方式。

智慧加上品格才是教育真正的目标。

The soul is the living bridge between the spirit and the body.

The obligation of subjects to the sovereign is understood to last as long, and no longer, than the power lasteth by which he is able to protect them.

追求智慧的路上，没有终点。
