It can be said vividly: what is a person?

"I undoubtedly believe that self-knowledge is the essence of understanding. At this point, I am famous for the temple of Apollo in Delphi (an ancient Greek city). Introduction and explanation. ) The inscription is consistent, that is,' Know yourself!' "(Plato's Tchami di).

"People are vegetarians in their mother's arms and pure animals in childhood. It takes twenty years to develop from these States to the maturity when rationality begins to appear. It will take three thousand years to know a little about his structure. It takes infinite time to understand something in your soul. But it only takes a moment to kill him. " (Voltaire's philosophical dictionary. General thinking about people)

Through general observation, we can find that people have the same characteristics as monkeys, gorillas, pigs, dogs, horses and cows. So we say that man is an animal. At the same time, there are obvious differences between humans and other animals. In this comparison of differences, we can know some characteristics of people. "The most obvious difference between human beings and animals is that animals are largely driven by their senses, rarely consider the past or the future, and only live for the present. However, because people are naturally rational, they can understand the relationship between things, see the causes of all things, understand the reciprocity of cause and effect, and make analogies, so it is easy to examine the whole process of their lives and make necessary preparations for the actions of life. " (Cicero's On Obligations)

"We must be asked to regard human beings as selected members of the universe, the smartest creatures! But in fact, human beings are between beasts, sometimes biased towards one kind and sometimes biased towards another; Some people are becoming more and more sacred, some people have become beasts, and most people maintain the doctrine of the mean. " (Plotinus's Nine Chapters). The sixth ")

An experiment shows that the human soul not only exists, but also has weight. The direct conclusion of this experiment is that when people die, their weight suddenly decreases by a few grams. -Is it the dissipation of something in the human body at the moment when the physiological function stops completely? Just like we can't feel our weight loss. At the moment of death, is it the divergence of soul or the divergence of matter? Soul is the essence of life. "Soul is the cause or root of life. The words cause and root have many meanings. However, we only say that the soul is the cause of its carrier in the sense of being equivalent to the three senses we clearly know. These three meanings are: (a) the source or origin of movement, (b) the purpose and (c) the essence of all living things. " (Aristotle's On the Soul)

"The shape is vivid, and the likes and dislikes are hidden." (Chen Guying's "Zhuangzi's Today's Note and Today's Translation" Zhonghua Book Company 1983 Edition)

Man is half an angel and half a devil.
