Chuang Tzu 2.5

Among the men of old their knowledge reached the extreme point. What was that extreme point? 

Some held that at first there was not anything. This is the extreme point, the utmost point to which nothing can be added. 

A second class held that there was something, but without any responsive recognition of it on the part of men. 

A third class held that there was such recognition, but there had not begun to be any expression of different opinions about it. 

It was through the definite expression of different opinions about it that there ensued injury to the doctrine of the Tao. It was this injury to the doctrine of the Tao which led to the formation of partial preferences. 

Was it indeed after such preferences were formed that the injury came? Or did the injury precede the rise of such preferences? If the injury arose after their formation, Kâo's method of playing on the lute was natural. If the injury arose before their formation, there would have been no such playing on the lute as Kâo's. 

Kâo Wan's playing on the lute, Shih Kwang's indicating time with his staff, and Hui-tsze's giving his views, while leaning against a dryandra tree were all extraordinary. The knowledge of the three men in their several arts was nearly perfect, and therefore they practiced them to the end of their lives. 

They loved them because they were different from those of others. They loved them and wished to make them known to others. 

But as they could not be made clear, though they tried to make them so, they ended with the obscure discussions about "the hard" and "the white." 

And their sons, moreover, with all the threads of their fathers' compositions, yet to the end of their lives accomplished nothing. 

If they, proceeding in this way, could be said to have succeeded, then am I also successful; if they cannot be pronounced successful, neither I nor any other can succeed. 

Therefore the scintillations of light from the midst of confusion and perplexity are indeed valued by the sagely man; but not to use one's own views and to take his position on the ordinary views is what is called using the proper light.
