In cybernetics, there is a famous black box theory. It means that when people cannot recognize, open, or directly observe the internal state from the outside, they will regard the entire system as an opaque and closed "black box". People have no way of knowing the complex structure and wonderful principles in it. They only know that if you input from one end, you will get a certain result at the other end.
The interesting thing about this theory is that there is no isolated thing among all things in the world, and there must be some inseparable relationship between all things. At a higher level, it is something that can be described as "the law of cause and effect" or "fate". Even if we can't figure out the rules, can't see the details, and can't find the clues, it still happens in this world every moment, telling us that real and specific actions are definitely creating causes and results.
