Faith is an extremely strong belief in a thing or a sentence. Like religion, or some political views. What's it like to have faith ... generally speaking, it's more open-minded, more open-minded, and resolute in doing things regardless of consequences. For example, for some devout Christians, even if a robber points a gun at each other and he has a gun in his hand, he is unwilling to shoot at each other because he believes God's warning not to kill anyone (Article 6 of the Ten Commandments of Moses); For other devout Muslims, it is normal to kill their enemies with their own lives as weapons, because this is a holy war, and their beliefs tell them that this will enable them to enjoy eternal happiness after death. In fact, the same is true of devout Christians, but there are not many Christians who are so devout in this respect now; For many people in the early days of the People's Republic of China, it doesn't matter how much they suffer now, because their actions will inevitably lead to the arrival of a capitalist society. At that time, they or their descendants will no longer have to eat these hardships and be tired of them. For people who believe in democracy, no matter what problems they have, they hope to solve them through more democracy, because they firmly believe that if we are democratic enough, these problems will not appear. In short, if you don't have faith, you will usually live more tired than people with faith.
As for myself, I can only say that I once had faith. As you can see, faith often depends on irrationality, that is, what cannot be proved by reason or what has not yet been proved is the breeding ground of faith; Because it is easier to predict the future than the world after death, as a religion, * * * cannot be as powerful and powerful as religion. Fortunately, it doesn't have to be a belief from the beginning. Many theoretical physicists believe that "the universe must be simple and beautiful", but once the formula used to explain the whole universe finally proves to be huge and complicated, they have to give up their beliefs. Therefore, the more rational a person is, the farther away his belief is from himself, and the more tired he will live. Of course, this is not to say that reason is not good. Personally, it doesn't matter to live a little tired for rational thinking.
What needs to be added is that faith is not necessarily a shining thing. At the beginning of World War II, many Germans believed that Aryans were the best race and were destined to rule the world, which was also a belief. Money is also a kind of faith. As a kind of belief, the theory of racial superiority and money worship are not evil things. Just believe it, but it will inevitably conflict with people who don't believe it.
