Lao Tzu deprecates the value of sagacity in Chapter 19 because he views it as a desire that people have rather than a way that should be followed. To Exterminate learning, the sage, benevolence is very hard to accept at first. After all, the sage is highly regarded throughout the scripture. However, in Chapter 81, Lao Tzu mentions that "He who has wide learning does not know." According to the Way, desires should be limited and an individual's desire to gain more knowledge may be because of the fact that he may want to use his wisdom to promote cleverness in order to profit through deceit. Lao Tzu, therefore, illustrates the belief that wisdom can be detrimental if it is used incorrectly, but he holds sages under a positive light in a lot of instances where the sage uses his wisdom to promote the Way. "In governing the people, the Sage empties their minds, fills their bellies, weakens their wills, and strengthens their bones. He keeps them innocent of knowledge and without desire, and where they have knowledge, he keeps them from acting on it (Chap. III)." Lao Tzu, therefore, uses the term
sage differently throughout the book to demonstrate the belief that wisdom is only beneficial in the right hands; only those individuals who wish to use their sagacity to promote the Way should attain wisdom, not those who wish to use their knowledge for personal profit. The term
sage denotes wisdom, but this wisdom is detrimental when put in the wrong hands. The Sage "empties" the minds of others because these
others are the ones who would use their knowledge for their own gain and not for promoting the true essence of what The Way preaches.
The concept of the uncarved block illustrates the idea of purity and purity is what The Way preaches. Without any adornments or modifications, the uncarved block is like the individual who keeps it simple and lives his life by embracing his surroundings rather than questioning them. To be truly pure, a thing would have to be untampered with. This is what LaoTzu tells us we should do with his words. Take them purely, without adding to, or contaminating them with worldly elements.If we're able to do this, then we too become like the uncarved block of wood and revert back to being a natural being. In being a natural being, we then can relate to all things natural and enjoy life as it was meant to be. The Way is to hold to the uncarved block, the universal mystery, without the urge to name and analyse, classify and dissect. It is to embrace time and change and to let go of worldly objectives. That is why the Way is straightforward but intensely difficult. That is why it cannot be reached by an act of reason but is in itself wholly reasonable.
