Is there a primary or secondary cause for an effect?

There are two points to note about the causal relationship in materialist dialectics: there must be an effect if there is a cause, and there is an effect but not necessarily a cause.

When using causal relationships to analyze, it is first necessary to determine whether a causal relationship is constituted. Generally speaking, the cause of an outcome is the transformation or disappearance of a contradictory relationship, not one aspect of the contradiction. In addition, it is important to note that causality is not common to all connections.

The example you gave is very confusing, but the reason why the average person cannot solve the primary and secondary problem of cause is because it is difficult to distinguish between two points: first, whether there is a causal relationship? Second, who are the two sides of the causal relationship?

The contemptible view is that the moment the deal is completed, a causal relationship does arise. But the reason is neither the buyer nor the seller, but the transaction itself,—— or rather, the cause of the result of the sale is the act of buying and selling, not the elements that constitute it.

In other words, the buyer and the seller are only the elements of the person who constitute the act of buying and selling, and not the act of buying and selling itself.

Jump out a little bit and analyze it a little bit, and it will be easier for you to understand. The act of buying and selling actually constitutes a commercial act, which embodies the relationship between people. To complete the sale, on the one hand, the buyer and the seller - that is, the human element, and the buyer and the seller need their respective commodities, either currency or commodities,—— which are the elements of things.

Together, these two elements constitute the material elements of the act of buying and selling, and in fact, the act of buying and selling generally also needs the element of consciousness, that is, demand: exchange can only occur when both the buyer and the seller need to exchange. In addition, the market is also indispensable.

Therefore, the occurrence of buying and selling behavior requires four major elements: one is demand, the second is people, the third is things, and the fourth is the market.

The final conclusion is that in causality, the result is born because of the transformation or disappearance of some contradiction, not because of some element of the contradiction. Just like commodity trading, it is impossible to buy or sell alone. Therefore, the above ones are all wrong, superficial, and do not see the essence of the problem.

1. Everything is a contradiction, and there is a contradiction between primary and secondary, so the cause of the result is also a contradiction, and there is also a distinction between primary and secondary. The main aspect of the contradiction determines the nature of the contradiction, and the secondary aspect of the contradiction will also be transformed into the main aspect of the contradiction under certain conditions. To be specific.

2. In the contradiction of "buying things", buying is the main thing and selling is secondary; "Selling something", selling is primary, buying is secondary. You buy my stuff, for you, buying is the main thing, for me, selling is the main thing. But buying and selling are indispensable, and the primary and secondary are based on the specific problem.

There is a priority in everything.

Analyze from different standpoints, which is the key point and which is not the key. This is the key to solving the problem.
