In which chapter of "Mencius Gaozi 1" is the sentence "food, sex, and sex" found?

This sentence appears in the fourth section of "Mencius Gaozi"

"The nature of food and sex" is often mistakenly attributed to Mencius. In fact, although this sentence comes from "Mencius Gaozi 1", it was not said by Mencius.

Gaozi was a young philosopher. He was very dissatisfied with Mencius's view of "human nature is good", so he came to debate with Mencius. During the process, Gaozi said, "Eating and sex are the same as sex," which means that appetite and sexual desire are both human nature. For this debate about the nature of human nature that took place more than 2,000 years ago, it doesn't really matter who wins in the end. What is important is that this sentence was recorded openly in the Confucian classic "Mencius", and since then it has become a classic for ancient people to discuss the nature of appetite and sexual desire.

Dr. Zhang Jingsheng gained notoriety in his early years when he published "The History of Sexuality" while teaching at Peking University. Around 1948, when I had nothing to do in my hometown, I opened a column in Shantou's "Daguang Daily" and wrote "New Food Classic". As the pioneer and founder of modern sexology in China, it must be very painful to be deprived of the right to continue research and publish in your favorite academic field. However, the leap from sexology to dietetics is really huge. Jumping. But if we look at it from the perspective of "food, sex, and sex," then appetite and sexual desire are both human physiological instincts. Even if they have little in common, at least they are not as unrelated as they seem on the surface.

Based on the available information, Dr. Zhang’s research on diet can be traced back to 1934 or earlier. Because at that time, a literary young man named Zhunzhi published an article called "Impressions of Zhang Jingsheng" in the "Decameron" magazine, which mentioned: "The doctor published the "Food Classic" in "Qingguang" and was promoting nutrition. Food, food is the most important thing for the people, and food and sex are also important. "Qingguang" is a supplement to "Current Affairs News". Although the newspaper is mainly based in Shanghai, it can be regarded as a national one. Big newspaper.

Despite this, we cannot conclude that the "New Food Classic" published in "Da Guang Bao" is the doctor's old work. There is a reference in "New Food Classic": "Let me take my husband as an example. I am sixty years old, but I can walk dozens of miles every day... Therefore, it can be said that sixty is still equal to thirty." It’s a joke, if my wife allows me, I can still marry a wife and have children.” The doctor was born in 1888 (died in 1970), which should be 1948 when he was sixty. It has been more than ten years since the "Food Classic" to the "New Food Classic", so it is possible to make major additions and deletions when revising the old work.

The "New Food Classic" is rich in content, including "Food Revolution and Medical Revolution", "Food and Exercise and Endocrine", "Food and Sexuality and Lust", "Hunger Strike and Spiritual Diet", "Hungry People" "Food Methods - Utilization of Salt and Water", "Basic Recipes of Vegetarian Fruit Food" and other chapters, and the appendix also includes "Preliminary Food Etiquette".

On the issue of the relationship between food and color, "New Food Classic" " put forward some bold conjectures, such as thinking that food is related to human temperament and lust. European and American white people eat meat for three meals, so they have a bad temper, their whole body and excrement have a gamey smell, and they cannot even endure sexual intercourse. The main oriental people have a peaceful temperament, and because the food contains a lot of fiber and is tough, not only the sex lasts long, but also has a clean smell. Take Xiang Fei as an example). ”

The "New Food Classic" also absorbed the new results of nutrition at that time, put forward the proposition of scientific diet, and even listed the vitamin (vitamin) content of some foods, which was unprecedented.
