養生主

養生主 (On the preservation of life)
吾生也有涯，而知也無涯。以有涯隨無涯，殆已！已而為知者，殆而已矣！
Translation
I have realized that human life is limited, however the knowledge is without a limit; To use one’s limit life and pursuit the limitless knowledge, one is doomed to failure. If however that one believes he knows, he is already in danger.
Note
I am taking an excursion to Chuang Tzu, who is considered to be the one after Lao Tzu in Taoism.
This work is written more than 2000 years ago, and yet, Chuang Tzu had already realized the limitless nature of knowledge. The advance in science only proves his point. The world we live in is limitless in every direction. To the big side, there is the universe; to the small side, there is the atom. We can say that the world is infinitely big and infinitely small. If we believe that human is made of the chemical elements that composed the body, which indeed it is, then the action of these chemical elements is fascinating. What makes this combination of the atoms act this way? How can the lifeless atoms and chemical elements realize their own existence?
