Anybody who has been seriously engaged in scientific work of any kind realizes that over the entrance to the gates of the temple of science are written the words: Ye must have faith.

知识可以传达，但智慧不能。人们可以找到智慧，活在其中，通过智慧得到坚定，创造奇迹，但却无法传达和教授。

The work is about presence and absence.

我们不是从祖先那里继承皮革，而是从子孙那里借来的。
