Traditional education taught that human economic development progressed from hunting to stock farming and then to agriculture. However, the only real difference is that stock farming is an economic method of obtaining food by domesticating livestock, while agriculture involves domesticating plants. Therefore, this three-stage development theory is no longer accepted. Instead, the development of human civilization can be seen in the evolution of transportation. To understand the nature of how the world changes, we should observe the development of transportation. The increasing speed of movement is the main evidence that society is changing rapidly. - Joseph’s “just my thoughts”
There are two kinds of knowledge in the world. The knowledge I can explain, and understand I know but cannot explain. To explain it to others, you must see the essence of that knowledge. The knowledge that others cannot understand means that the person describing it does not know its nature. So the secretary becomes wise. - Joseph’s “just my thoughts”
