There are various types of knowledge
On the other hand, Protagoras believes that the purpose of knowledge is to know what to say and how to say it. It is about improving the image of oneself in the eyes of others. In ancient times, Techné (Skill) was considered a form of knowledge. It was not systematically taught but learned through observation and practical experience. It was about knowing how to do something and how to accomplish it. The concept of Technology emerged around the 1700s. It was defined as the knowledge that improves the productivity of workers by providing them with knowledge. It was recognized that knowledge could be a valuable resource for workers, leading to increased productivity. The term Techne (Techné) + logy symbolizes the invention of technology. It combines the secret skill of Techné with the suffix "logy" which represents a system. The development of technology led to the creation of machines. For example, the invention of the steam engine by Watt in 1776 revolutionized the productivity of workers. This new system of "worker + machine" was far more productive than individual workers. However, this also created a significant gap between the capitalists who owned the machines and the workers who did not. The improvement of tools and machines became the focus of knowledge. It was about enhancing productivity by improving the tools used in various industries. In the late 19th century, management techniques emerged. Taylor introduced scientific management, which applied knowledge to the study, analysis, and assembly of physical labor. Ford also implemented the Ford system, which aimed to improve productivity through the analysis and improvement of workers' tasks. These management techniques greatly increased productivity through education and training. In the 1950s, Drucker introduced the concept of meta-management. This concept focused on improving the knowledge itself that is used to enhance productivity. It aimed to improve the productivity of knowledge by improving the knowledge for productivity improvement. In summary, the purpose of knowledge has evolved from self-recognition to improving communication skills, to enhancing skills and technology, to improving tools and machines, to optimizing work processes, and finally to improving the productivity of knowledge itself.
