"If you want to know the taste of a pear, you must change the pear by eating it yourself. If you want to know the theory and methods of revolution, you must take part in revolution. All genuine knowledge originates in direct experience"

Mao Zedong's quote is a phone call to activity, urging people to take part in transformation in order to get genuine knowledge. He recommends that knowledge can not be gotten through merely checking out or reading about something, yet instead through straight experience. He utilizes the instance of a pear to highlight his factor, claiming that can not know the preference of a pear without actually eating it. Similarly, one can not recognize the theory and methods of revolution without participating in it. Mao Zedong's quote motivates people to take action as well as gain expertise via straight experience, instead of relying on pre-owned information. This is a vital pointer that expertise is not something that can be obtained passively, but rather something that should be proactively looked for.
