According to the logic of the philosopher Schopenhauer, the higher the level of intelligence, the higher the degree of suffering; the more one has, the greater the sensitivity to suffering. However, the most common way to relieve suffering is material dependence. Almost all of the heroes of the recent past have been dependent, especially on tobacco, such as Churchill and Mao, and Lin Biao, who is constantly high on melon seeds in the domestic films of the three major battles. Substance dependence is a powerful defense mechanism, and according to psychoanalyst Warburg, this controlling defense mechanism is primarily used to vanish into the body so as to completely take care of the outside world. After we benefit mentally and psychologically from our dependence on a substance, we reinforce our dependence on it. As times change, the dependence on tobacco and melons evolves into internet addiction. Addiction is obviously more extreme than dependence, and drug addiction is the most extreme manifestation of mental and physical dependence. However, any substance dependence cannot be cured by scientific knowledge alone, for example, dependence on tobacco and alcohol, we all know that smoking is harmful to health and sudden death due to drunkenness is also very common, so is it that after seeing these we all start to quit smoking and drinking? Look around us how many smokers and drunk people will know. This is like many “super-scientific” smoking cessation manuals, which inevitably start out by promoting how horrible smoking is, and they make the mistake of thinking that people will quit because they fear death. In fact, from the perspective of both loss and gain, there are situations where some people are more concerned with gain, or instant gratification, and thus ignore the part they have lost.
