Li Shizeng (; 29 May 1881 – 30 September 1973), born Li Yuying, was a Chinese educator, promoter of anarchist doctrines, political activist, and member of the Chinese Nationalist Party in early Republican China.

After coming to Paris in 1902, Li took a graduate degree in chemistry and biology, and then along with Wu Zhihui and Zhang Renjie, cofounded the Chinese anarchist movement. He was a supporter of Sun Yat-sen. He organized cultural exchange between France and China, established the first factory in Europe to manufacture and sell beancurd, and created Diligent Work-Frugal Study programs which brought Chinese students to France for work in factories. In the 1920s, Li, Zhang, Wu, and Cai Yuanpei were known as the anti-communist "Four Elders" of the Chinese Nationalist Party.

Youth and early career Though his family was from Gaoyang County, Zhili, Li was brought up in Beijing. His father was Li Hongzao. Li studied foreign languages. When Li Hongzao died in 1897, the government rewarded his sons with ranks which entitled them to hold middle-level office. The title for this ranking was known as Lung-Chang.

In 1900, the family fled the Boxer Uprising and invasion of the Allied Armies. After their return to Beijing, Li attended a banquet at the home of a neighboring high official who had been a friend of his father. There he met Zhang Renjie, the son of a prosperous Zhejiang silk merchant whose family had purchased him a degree and who had come to the capital to arrange a suitable office. The two quickly discovered that they shared same ideas for the reform of Chinese government and society, beginning a friendship which lasted the rest of their lives. When Li was chosen in 1903 as an "embassy student" to accompany China's new ambassador Sun Baoqi to Paris, Zhang had his family arrange for him to join the group as a commercial attache. Li and Zhang traveled together, stopping first in Shanghai to meet with Wu Zhihui, by then a famous radical critic of the Qing government, where they also met Wu's friend, Cai Yuanpei.

Anarchism and France

At the time, since France had the reputation of being the home of revolution, Chinese officials were reluctant to sponsor study there. Li and Zhang, however, were well connected, and arrived in France, December 1902, accompanied by their wives. Ambassador Sun was indulgent and allowed Li to spend his time in intense French language study, but Li soon resigned from the embassy to enroll in a graduate program in chemistry and biology at in Montargis, a suburb south of Paris. In three years he earned his degree, then went to Paris for further study at the Sorbonne University and the Pasteur Institute. He announced that he would break with family tradition and would not pursue an official career. Zhang, meanwhile, began to make his fortune by starting a Paris company to import Chinese decorative art and curios. Li and Zhang persuaded Wu Zhihui to come to Paris from Edinburgh, where he had been attending university lectures. Li, Zhang, and Wu did not forget their revolutionary goals. On route back to China for a visit, Zhang met the anti-Manchu revolutionary, Sun Yat-sen and promised him extensive financial support. On his return to Paris in 1907, Zhang led Li and Wu to join Sun's Tongmenghui (Chinese Revolutionary Alliance).

The Paris Anarchists

The three young radicals had come in search of ideas to explain their world and of ways to change it. They soon discovered the fashionable doctrines of anarchism, which they saw as a scientific and cosmopolitan set of ideas which would bring progress to China. The key point of difference with other revolutionaries was that for them political revolution was meaningless without cultural change. A group of Chinese anarchists in Tokyo, led by Liu Shipei, favored a return to the individualist Daoism of ancient China which found government irrelevant, but for the Paris anarchists, as the historian Peter Zarrow puts it, "science was truth and truth was science." In the following years they helped anarchism to become a pervasive, perhaps dominant, strand among radical young Chinese.

The Paris anarchists argued that China needed to abolish Confucian family structure, liberate women, promote moral personal behavior, and create equitable social organizations. Li wrote that "family revolution, revolution against the sages, revolution in the Three Bonds and the Five Constants would advance the cause of humanitarianism." Once these goals had been accomplished, they reasoned, the minds of the people would be clear and political improvement would follow. Authoritarian government would then be unnecessary.

Although these anarchists sought to overthrow Confucian orthodoxy, their assumptions resonated with the idealistic assumptions of Neo-Confucianism: that human nature is basically good; that humans do not need coercion or governments to force them to be decent to each other; and that moral self-cultivation would lead individuals to fulfill themselves within society, rather than by liberating themselves from it. For these anarchists, as for late imperial Neo-Confucians, schools were a non-authoritarian instrument of personal transformation and their favored role was as teacher.

In 1906 Zhang, Li, and Wu founded the Chinese anarchist organization, the World Society (世界社 Shijie she), sometimes translated as New World Society. In later years, before moving to Taiwan in 1949, the Society became a powerful financial conglomerate, but in its early phase focused on programs of education and radical change.

In 1908, the World Society started a weekly journal, Xin Shiji 新世紀週報 (New Era or New Century; titled La Novaj Tempoj in Esperanto), to introduce Chinese students in France, Japan, and China to the history of European radicalism. Zhang's successful enterprise selling Chinese art funded the journal, Wu edited it, and Li was the major contributor. Other contributors included Wang Jingwei, Zhang Ji, and Chu Minyi, a student from Zhejiang who accompanied Zhang Renjie back from China and would be his assistant in the years to come.

Li eagerly read and translated essays by William Godwin, Pierre-Joseph Proudhon, Élisée Reclus, and the anarchist classics of Peter Kropotkin, especially The Conquest of Bread and Mutual Aid: A Factor of Evolution. Li was struck by their arguments that cooperation and mutual aid were more powerful than the Social Darwinist forces of competition or heartless survival of the fittest. Li was also impressed by conversations with the Kropotkinist writer Jean Grave, who had spent two years in prison for publishing "Society on the Brink of Death" (1892) an anarchist pamphlet.

Progress was the legitimizing principle. Li wrote in 1907 that Progress is advance without stopping, transformation without end. There is no affair or thing that does not progress. That is the nature of evolution. That which does not progress or is tardy owes it to sickness in human beings and injury in other things. That which does away with sickness and injury is none other than revolution. Revolution is nothing but cleansing away obstacles to progress.

The Paris group worked on the assumption that science and rationality would lead toward a world civilization in which China would participate on an equal basis. They espoused Esperanto, for instance, as a scientifically designed language which would lead toward a single global language superior to national ones. Their faith in moral self-cultivation led Li to adopt vegetarianism in 1908, a lifelong commitment. Yet he also believed that individuals could not liberate themselves simply by their own will, but needed strong moral examples of teachers.

Xin Shijie even called for the reform of Chinese theater. Li regretted that reform had stopped at halfway measures such as introducing gas lights. He called for deeper reforms such as stage sets rather than bare stage and allowing men and women to act on the same stage. Li consulted several French friends before deciding to translate two contemporary French plays, L'Echelle, a one-act play by Edouard Norès (?-1904), which he translated as Ming bu ping, and Le Grand Soir by Leopold Kampf (1881–1913), which he translated as Ye wei yang.

By 1910, Zhang Renjie, who continued to travel back and forth to China to promote business and support revolution, could no longer finance both Sun Yat-sen and the journal, which ceased publication after 121 issues.

Soy factory and Work-Study program The anarchists Li and Zhang Renjie also owned businesses to finance their political activities. As Zhang expanded his import business, Li realized that he could put his scientific training to use in manufacturing soy products. He felt that beancurd (doufu), would appeal to the French public as characteristically Chinese.

In 1908 Li opened a soy factory, the Usine de la Caséo-Sojaïne, which manufactured and sold doufu (beancurd). p. 125

The plant, housed in a brick building at 46–48 Rue Denis Papin in the suburb of La Garenne-Colombes a few miles to the north of Paris, produced a variety of soy products. There was little market for bean-curd jam, soy coffee and chocolate, eggs, or bean-curd cheese (in Gruyere, Roquefort or Camembert flavors), but soy flour and biscuits sold well. The company offered free meals to Chinese students, who gathered also to discuss and debate revolutionary strategy. Sun Yat-sen visited the factory in 1909, and wrote: "My friend Li Shizeng has conducted research on soybeans and advocates eating soybean foods instead of meat."

Li planned the Work-Study program as a way to bring young Chinese to France whose study would be financed by working in the beancurd factory and whose character would be uplifted by a regimen of moral instruction. This first Work-Study program eventually brought 120 workers to France. Li aimed to take these worker-students, who he called "ignorant" and "superstitious", and make them into knowledgeable and moral citizens who on their return would become models for a new China. The program instructed them in Chinese, French, and science and required them to abstain from tobacco, alcohol, and gambling.

Li returned to China in 1909 to raise further capital for the factory. Again using family connections, he secured an interview with the governor of Zhili, Yang Lianpu, a friend of his father's, and secured a contribution. His father-in-law, Yao Xueyuan (1843–1914), head of the salt merchants of Tianjin, solicited the national community of salt merchants for investment. In six months Li raised some $400,000. He arrived back in France with five workers (all from Gaoyang, his home district), and a supply of soybeans and coagulant.

France In 1905, while he was still a graduate student, Li presented his first paper on soy at the Second International Dairy Congress in Paris, and published it in the proceedings of the conference. In 1910 he published a short treatise in Chinese on the economic and health benefits of soy beans and soy products, especially doufu, which he maintained could alleviate diabetes and arthritic pain, and then in 1912 Le Soja in French. At the annual lunch of France's Society for Acclimatization (Société d'Acclimatation), in keeping with its tradition of introducing new foods from little-known plants, Li served a meal of vegetarian ham (jambon végétal), soy cheese (fromage de Soya), soy preserves (confitures de Soya, such as crème de marron), and soy bread (pain de Soya).
