How to exercise logical thinking ability?

The brain is like a muscle. The more you practice, the more developed you become. Schwarzenegger's muscles were not connected in a few days. Regular practice will be effective. Training memory is also skillful. The usual method is to associate what you want to remember with what you are familiar with, which is easy to remember. At that time, you will get what you originally wanted to remember through reverse association. And the method I know and tried is painting. The brain is better at remembering image information than writing symbols. What you want to remember is transformed into graphics through your own creativity and drawn on paper, and the colors are different and colorful. Think about those photos. There are many ways to remember, and there are also many bookstores. As long as you have determination, your efforts will progress. People's memory begins to decline after the age of 30, so they should study more when they are young. 1, flexible use of logic. Being able to think logically does not mean being able to solve difficult problems. Logically speaking, there is a problem of using skills. How come practice makes perfect? Learning mathematics means that you solve more problems, and you know what must happen to solve these problems. This can be called mathematical philosophy. Generally speaking, this is the difference between liberal arts students and science students, not whether they have logical thinking. At the same time, in reality, people think that logical thinking ability is strong, but in fact, thinking ability is strong, and there is no distinction between arts and sciences. Moreover, this idea is not logically obtained, but logically explained. 2. Participate in the debate. Ideas are produced in debates, including self-debate and self-debate. For example, regarding whether sovereignty is higher than human rights or vice versa, I think the sovereignty to protect human rights is higher than human rights, and it cannot include the sovereignty that causes the king to enjoy the baby feast. Since sovereignty must be defined, the former can be established conditionally. The reason for this understanding is that this issue is controversial, otherwise it will not be thought about. 3. Stick to common sense. In fact, it is easy for me to draw a personal conclusion about human rights, because no matter what big-name experts say, there is only one reason why I disagree. I insist that no one wants their legal rights to be violated unless they have to. Because of this common sense, it is necessary to analyze sovereignty, for example, the state has the right to retain its army, and its citizens will be required to assume different obligations under different circumstances. It seems to violate human rights in wartime, but it is a payment for everyone's security needs, and sovereignty must be justified. Obviously, it is very important to stick to common sense and draw a logical conclusion. It should be noted that we can't stick to the conclusion of induction, because induction is always a part of inductive things, and it can't be all. Violate some common sense, such as philosophy. China people often use philosophy to explain problems, always from one general to another, so they don't know what to say, as if they can't think logically, which is ridiculous. 4. Dare to question. Including authoritative conclusions and personal conclusions, if the logical explanation is obviously unreasonable.
