_A good cook changes his knife once a year because he cuts, while a mediocre cook has to change his every month because he hacks. I've had this knife of mine for nineteen years and have cut up thousands of oxen with it, and yet the edge is as if it were fresh from the grindstone. There are spaces between the joints. The blade of the knife has no thickness. That which has no thickness has plenty of room to pass through these spaces. Therefore, after nineteen years, my blade is as sharp as ever.10 _Lao Tzu and Chuang Tzu did not see themselves as founders of any formal religion. They merely described the obvious, encouraging others to be a part of nature and not its antagonist. Their movement, now called Philosophical Taoism, was eclipsed during the Han Dynasty (206 B.C.-A.D. 220) in official circles by various other systems of thought, most particularly Confucianism (which stressed obedience to authority-- both that of elders and of superiors--and reverence for formalized learning, not to mention the acceptance of a structured hierarchy as part of one's larger social responsibility). However, toward the end of the Han era there arose two new types of Taoism: an Esoteric Taoism that used physical disciplines to manipulate consciousness, and a Popular Taoism that came close to being a religion in the traditional mold. The first was mystical Esoteric Taoism, which pursued the prolonging of life and vigor, but this gave way during later times to Popular Taoism, a metaphysical alternative to the comfortless, arid Confucianism of the scholarly establishment. The post-Han era saw the Philosophical Taoism of Lao Tzu and Chuang Tzu emerge anew among Chinese intellectuals, actually coming to vie with Confucianism. This whole era witnessed a turning away from the accepted values of society, as the well-organized government of the Han era dissolved into political and intellectual confusion. Government was unstable and corrupt, and the Confucianism which had been its philosophical underpinning was stilted and unsatisfying. Whenever a society breaks down, the belief system supporting it naturally comes under question. This happened in China in the third and fourth centuries of the Christian era, and from it emerged a natural opposition to Confucianism. One form of this opposition was the imported religion of Buddhism, which provided a spiritual solace missing in the teachings of Confucius, while the other was a revival among intellectuals of Philosophical Taoism.
