1. Ancient Greek Plato's "Parmenides": "It seems that whether one exists or does not exist, and other things exist or do not exist, they are in the manner and mode of all things, and for them Either by themselves or between them, they appear to exist or not."

2. Ancient Greek Plato's "Utopia": Justice is doing the right thing in the country, when each individual only does one thing. When a person does a job related to the country, and this job is most suitable for his nature, then the country will have justice.

3. Ancient Greece Plato's "Symposium": All this lies in the original character of human beings: we are originally complete, and the hope and pursuit of that completeness is the so-called love.

4. Ancient Greece Plato's "Minos": Etiquette involves our way of life, the "good and evil" of our souls, and is closely related to our "eternal happiness". Without understanding what Dharma is, it is impossible to formulate good Dharma. And the political unity without the maintenance of good laws will obviously not be a "happy" unity.

5. Ancient Greek Plato's "Sophists": Wise men are people who collect money to teach the children of wealthy people. They are also people who sell goods imitated by the soul. They are really ignorant but pretend to have knowledge. Deceiving young people.
