What is nature and what is nature?

Human nature is formed under certain social system and certain historical conditions. Therefore, nature does not always stay at "the beginning of life, human nature is good", but is influenced by social environment. Humanity is the humanity that fundamentally determines and explains human behavior. Human nature is greedy.

The "original heart" refers to the "heart of shame and evil", and the "righteousness" comes from the "heart of shame and evil". Only with the "heart of shame and evil" can we act according to the principle of "righteousness" and sacrifice our lives for righteousness at critical moments. Nature is good.
