Underlying logic + environmental variables = methodology

By establishing the underlying logic, identifying the external environment, and deducing a methodology that adapts to the current situation.

1. The underlying logic of right and wrong

Three “views of right and wrong”

Jurist’s views of right and wrong (critic): Who has conclusive evidence ? Whose fault

Economist (policymaker): Who has the lowest total social cost? Whose fault

Businessman (real life): Who lost the most? Whose fault is it

——To determine who should be blamed after a loss occurs, it depends on whose loss is greater. When something goes wrong, blaming, complaining, and regretting are useless. They cannot change the outcome. If you suffer losses, you can only blame yourself, and only you can change the final outcome of the matter - rely on yourself, and you will be stronger if you make yourself stronger.

Human nature, morality and law

Human nature: Individuals pursue survival & reproduction.

Morality: restrain the humanity of individuals and achieve the prosperity of the group. Morality is not an inherent requirement of human nature. In most cases, morality is even anti-human nature. Precisely because morality is often anti-human, it requires a lot of guidance and restraint. Guidance uses methods such as propaganda and public opinion that have long-term but slow results, such as guidance through culture and values. Restraint adopts "violent" but immediate methods such as punishment and expulsion, such as through social structure, interest structure, law and other constraints.

Law: The moral bottom line for maintaining the existence of the group. People of every era will "draw a lowest line" for social norms in morality - the bottom line, and this bottom line is the law. Law is the first subset, morality that must be punished if violated.

——Human nature comes from the "selfish" gene. Morality is a "social contract" that is for the prosperity of the group and ultimately promotes the survival and reproduction of individuals, which is roughly achieved simultaneously. Morality is often anti-human. Law is a subset of morality and the moral bottom line for maintaining the existence of a group.

Three levels of wisdom in life: game, concentration, and choice

How to have a life in which you have the final say? Learn and have wisdom.

How to obtain success and happiness in life? Rely on wisdom.

In life, gaming is the third level of wisdom, concentration is the second level of wisdom, and choice is the first level of wisdom.

The wisdom of gaming: How to gamble - one must rely on mentality to win and be grateful. The second relies on strategy, tit for tat, tooth for tooth, eye for eye; your kindness should be a bit "edgy".

The wisdom of concentration: concentration is for longer-term goals, which can also be called "long-termism." The final victory is often the victory of time and the victory of long-termism.

The wisdom of choice: Learning to choose is often learning to give up - choose one and give up the others. Choice is sometimes more important than effort, but giving up is sometimes more important than choice. We should choose bravely, then enjoy the benefits and bear the disadvantages.

——Where do the gaps between people come from? It comes from whether you have wisdom and what level of wisdom you have. In life, gaming is the third level of wisdom, concentration is the second level of wisdom, and choice is the first level of wisdom. How to play the game, how to maintain concentration, and how to make choices all determine the direction of life - choose to do something, rely on long-termism to form your own concentration, and play games with the world again and again. I hope that in this complex and ever-changing world, we can all retreat unscathed and achieve multi-party win-win; we can reject temptation and maintain determination; we can have the courage to choose without regrets, do whatever we want without overstepping the rules; we can have wisdom and achieve success. own life goals.

Axiom System VS Logical Deduction

In a world with an axiom system, there are only things that can be proven and things that cannot be proven. The difference between masters and masters is the difference in IQ, not the difference in eloquence. Such as mathematics.

In most subject areas, there is no axiom system, such as economics. Because there is no axiom system and only relying on logical deduction, it is impossible to draw unquestionable conclusions. Therefore, researchers in these fields are more worthy of admiration.

Three suggestions for studying economics: First, learn from Li Bai and also learn from Du Fu. Be sure to listen both. The second is to find a counterexample for each model. Third, every theory has its premises.

——How to learn economics well? The first is to learn from Li Bai and Du Fu; the second is to find a counterexample for each model; the third is to remember that every theory has premises. Only in this way, what you learn is not "economics on the blackboard", but "useful economics" that can be abstracted from the real world and restored to the real world. The work of an economist is much more complicated than that of a mathematician. Only by studying economics in this way can you live up to their outstanding efforts. In fact, it’s more than just economics. All disciplines that are not based on axiomatic systems are the same. Therefore, before studying economics, I hope to remember three famous quotes. The first sentence is what Fitzrad said: "Holding two completely opposite ideas at the same time and still acting normally is a sign of first-class wisdom." Only in this way will you understand that to learn from Li Bai, you must also learn from Du Fu. The second place was said by Romain Rolland: "There is only one true heroism in this world, and that is to still love it after recognizing the truth of life." In this way, you will have the courage to find a hero for each model. Counterexample and continue using this model. The third sentence is what Charlie Munger said: "If I can't refute this point of view better than the smartest person in the world, I don't deserve to have this point of view." In this way, you can always remind yourself that every theory has premise.
