How to evaluate Mencius?

The book "Mencius" contains Mencius' systematic view of life and death, which is manifested in the attitude towards life that treats all life well, the values of life that sacrifice one's life for righteousness, and the pursuit of life that "a gentleman starts a business and there are successors". Mencius is one of the four books, which embodies all aspects of Mencius' thought, including his view of life and death. Mencius inherited and carried forward Confucius' view of life and death. His attitude towards life is to be kind to all life, emphasizing giving up life for righteousness, pursuing entrepreneurship and transcending death. Mencius, as the most important representative of Confucius' post-learning, inherited Confucius' thought of respecting and cherishing life and developed it to a new stage. Mencius' view of life and death is characterized by putting forward a broader concept of being kind to life. Mencius first put forward the specific proposition of being kind to himself, thinking that every part of the body should be cared for and maintained. He said: "People love their bodies as well as their bodies. If you love both, you will support both. Skin without size doesn't love it, so skin without size doesn't support it. " (Mencius Gao Zi) Caring for every part of the body is the embodiment of filial piety, and maintaining it on this basis is the treasure of life itself. Secondly, Mencius extended his kindness to life to all things in nature. When talking to Liang, he said, "It's harmless, but it's kind. When you see a cow, you can't see a sheep. A gentleman is to an animal, seeing its life, and can't bear to see its death; I can't bear to eat its meat when I hear its voice. Far cooking is also a gentleman.
