In this article, Mr. Tao Xingzhi disagreed with Wang Yangming's view that "knowing is the beginning of doing, and doing is the achievement of knowing", and proved that "doing is the beginning of knowing, and knowing is the achievement of doing" with life experience and scientific invention cases. Let's start with children. When we were young, we must have burned our hands and knew that the fire was hot. I don't know that snow is cold until I ice my hands, that sugar is sweet after eating it, and that stone is hard after touching it. Summer life has been tasted several times before I know the abstract heat. After a few cups of ice cream, you know the abstract cold. White sugar, brown sugar, sesame sugar, licorice and licorice have been eaten several times to know the abstract. I don't know what it feels like until I experience it and feel it.

Franklin, let the wind go, etc. Know that electricity can be led from the sky to the ground by a wire. Watt boiled water, and when he saw steam pushing the lid, he knew that steam could also push the machine. When Galileo dropped the balls with different weights on the Leaning Tower, he knew that the balls with different weights landed on some scientific inventions when China was a country. We can also see that traveling is the beginning of knowing, and knowing is the result of doing it. "

At the same time, he also borrowed the theories of "pro-knowledge", "smell knowledge" and "say knowledge" in Mo Bian to further prove that the full text is clear in logic and rigorous in argument.

1, "Familiarity is the foundation of all knowledge." Familiarity comes from personal experience, that is, from "walking"

2. "If you don't know the basics, you can't pick it up." It is derived from the "line". National knowledge is obtained from others, or passed down by teachers and friends, or conveyed by books, which can be classified into this category.

3. "'Speaking knowledge' is also rooted in' pro-knowledge'." Saying knowledge is inferred knowledge. "Hearing and speaking knowledge must be rooted in knowing each other before they can be effective." "Doing is the beginning of knowing, and knowing is the achievement of doing".
