Yes It is impossible to satisfy everyone, but it must meet the standards of most people. What I have learned is that people rely on words to alert some people, but the law can change people by force. There are many psychologically distorted people in the society who do things that undermine people's peace. Therefore, morality can't play a role at this time, and we can only rely on the law. I remember "Lara" said: "The ancients said, Confucius said, Mencius said, then Russell said, Nietzsche said, and so on. Those are other people's ideas, and we should have our own ideas. However, everyone has their own ideas. Isn't society chaotic? In fact, we don't have to suppress one or more of them. There is only one truth. If they investigate deeply, they will definitely find out the truth. " Law and morality can also be demonstrated in this way.
Protagoras is a supporter of the theory of relativity. Protagoras regards feeling as the standard of truth and calls it subjective idealism, but his view is different from subjective idealism. He put forward a famous proposition: "Man is the measure of all things", thinking that the existence of things is relative to people's feelings, and things are people's feelings. Now, things are independent of people's will, so I suggest the landlord look at Marxist philosophy. Truth has two aspects: absoluteness and relativity. Protagoras is a bit one-sided, just like the present metaphysical materialism. But I have to admit that he is a smart man and a master. Without their thoughts, there would be no present philosophy.
Written by myself, I hope the landlord will adopt 0.0. If possible, we can continue our discussion.
