Why Was the Spring and Autumn and Warring States Period the Freest Era for Chinese Thought

The Golden Age of Chinese Thought: Why Didn't It Last?

In the long river of Chinese history, there was an era that gleamed like a brilliant meteor streaking across the night sky—brief yet so dazzling that it could not be ignored. That was the Spring and Autumn and Warring States period, spanning over five hundred years from 770 BCE when King Ping of Zhou moved the capital eastward to 221 BCE when Qin Shi Huang unified the six states. During this time, the Chinese land witnessed the most spectacular intellectual feast in the history of human civilization. Names like Confucius, Laozi, Mozi, Han Feizi, and Sun Tzu have traversed more than two thousand years and continue to profoundly influence our ways of thinking and values. But why was it precisely this era that produced such free and vibrant thought? Why, in the two thousand years that followed, did such intellectual freedom never reappear?

A Collapsed Old Order: The Soil of Intellectual Freedom

Intellectual freedom never arises from nothing; it requires specific historical soil. The fundamental background for the explosion of thought during the Spring and Autumn and Warring States period was the complete collapse of the Western Zhou's feudal system.

In 1046 BCE, King Wu of Zhou defeated the Shang and established the Zhou dynasty, creating a political order centered on the feudal system and patrilineal kinship system. The Son of Heaven enfeoffed various lords, who in turn supported the Son of Heaven, and the entire realm was incorporated into a system of clear hierarchy and orderly arrangement. Within this system, "propriety" (li) was the highest code of conduct, and everyone stayed in their proper place, leaving little room for intellectual exploration.

However, by 770 BCE, the Rong barbarians attacked Haojing, forcing King Ping of Zhou to move the capital eastward to Luoyi, marking the end of the Western Zhou. In the subsequent Eastern Zhou, the prestige of the Son of Heaven plummeted. Though nominally still the "common master of all under Heaven," the Son of Heaven could not even govern his own territories properly. In 707 BCE, King Huan of Zhou led an army against the state of Zheng, only to be shot in the shoulder by a Zheng general, his heavenly authority utterly destroyed. Afterward, hegemons such as Duke Huan of Qi, Duke Wen of Jin, and King Zhuang of Chu rose in succession. "Propriety, music, and punitive expeditions emanate from the Son of Heaven" became "Propriety, music, and punitive expeditions emanate from the lords," ultimately devolving into "attendants commanding the state."

The old order had collapsed, but a new one had not yet been established. In this power vacuum, no unified authority could monopolize thought or suppress discourse. The various states competed fiercely with one another, and each lord sought ways to enrich his realm and strengthen his armies, thus adopting an open and even welcoming attitude toward various schools of thought and theories. This political multiplicity and competition created unprecedented fertile soil for the free growth of ideas.

Confucianism: Seeking Order and Benevolence in Chaos

Among the numerous schools of thought that flourished during the Hundred Schools of Thought, Confucianism was by far the most influential. Its founder, Confucius (551-479 BCE), came from a declining aristocratic family in the state of Lu. Throughout his life, he wandered from place to place, traveling through various states for fourteen years, yet never realized his political ideals.

Confucius's core philosophy centered on "benevolence" (ren) and "propriety" (li). "Benevolence" was inner moral cultivation—"do not do unto others what you would not have them do unto you"; "propriety" was external social norms, to be restored through the revival of Zhou ritual in order to rebuild social order. Confucius was no rigid reactionary. In an age when propriety and music had collapsed into chaos, he sought to find a path for human society based on morality rather than violence. He proposed "teaching without class distinctions," breaking the aristocracy's monopoly on education. According to tradition, he had three thousand disciples, seventy-two of whom were sages. He pioneered private teaching academies in China.

After Confucius, Confucianism split into various schools. Among the most important was Mencius (approximately 372-289 BCE). Mencius elevated Confucian thought to a startling height by explicitly proposing that "the common people are most precious, the state is secondary, and the ruler is least important." In an age of monarchy over two thousand years ago, for a thinker to dare declare that the people were more important than the ruler required enormous intellectual courage! Mencius also proposed the theory of human goodness, arguing that people are naturally endowed with goodness—the heart of compassion, the heart of shame and aversion, the heart of deference and respect, and the heart of right and wrong are all innate. This confidence in human nature provided the philosophical foundation for Confucian educational ideals.

Another important Confucian scholar, Xunzi (approximately 313-238 BCE), held the opposite view—the theory of innate evil—arguing that human nature tends toward evil and must be corrected through the education of propriety and righteousness. The fact that one school could accommodate such diametrically opposed viewpoints is itself the best proof of intellectual freedom in that era.

Daoism: Ultimate Questions Beyond Human Order

If Confucianism was concerned with how to govern society, Daoism concerned itself with more fundamental questions: What is the essence of the universe? How should humans exist?

Laozi was the founder of Daoism, though his identity remains mysterious to this day. According to legend, he was the keeper of the palace archives of the Zhou (equivalent to the director of a national library). In his later years, he rode a blue ox westward through the Hangu Pass, leaving behind the five-thousand-character Daodejing before disappearing into history. This work of merely five thousand characters became one of the most profound classics in Chinese philosophical history.

The core concept of Laozi is "Dao." "The Dao that can be spoken is not the eternal Dao; the name that can be named is not the eternal name." The Dao is the origin and principle of all things in the universe, yet it cannot be fully expressed in language. In politics, Laozi advocated "non-action governance," believing that the more rulers interfere, the more chaotic society becomes. The best governance is like "cooking a small fish"—minimal intervention, letting nature take its course. In Laozi's ideal of the "small state with few people," people "enjoy their food, admire their clothes, are content with their dwellings, and delight in their customs," with neighboring states so close they can hear each other's chickens and dogs, yet "the people grow old and die without visiting one another." Such thought in an age of frequent warfare was undoubtedly a profound reflection on endless military campaigns and aggressive warfare.

Zhuangzi (approximately 369-286 BCE) developed Daoist thought to its extreme. His writings are vast and uninhibited, brimming with unbridled imagination. The story of "Zhuangzi dreaming of a butterfly" asks profound questions about the boundaries between self and other: "I dreamed I was a butterfly, fluttering about happily. Now I do not know whether I am Zhuangzi who dreamed he was a butterfly, or a butterfly dreaming it is Zhuangzi." The magnificent image of the great roc soaring up ninety thousand li in "The Wandering of the Carefree" expresses longing for absolute spiritual freedom. When the king of Chu invited Zhuangzi to become his prime minister, Zhuangzi refused, preferring to "drag his tail through the mud" like a tortoise, crawling freely in the dirt rather than being enshrined in a temple and losing his freedom. In an age when lords competed for supremacy and everyone pursued power, Zhuangzi's choice represented a spiritual realm transcending worldly concerns.

Legalism and Mohism: Pragmatic Revolutionaries and Idealistic Practitioners

Legalism was the most revolutionary school of the Spring and Autumn and Warring States periods. Unlike Confucianism's pursuit of moral education, Legalism directly advocated using law and institutions to govern the state.

Shang Yang (approximately 390-338 BCE) was Legalism's most famous practitioner. In 356 BCE, with the support of Duke Xiao of Qin, he began his reforms, abolishing hereditary ranks and stipends, implementing a military merit system, rewarding agriculture and warfare, and standardizing weights and measures. Shang Yang's reforms fundamentally transformed Qin's social structure, turning a weak western state into a formidable military power. However, after Duke Xiao's death, Shang Yang was executed by the old nobility through dismemberment. Han Feizi (approximately 280-233 BCE) synthesized Legalist thought, proposing a unified theory of "law, technique, and power." His fellow student Li Si later became Prime Minister to Qin Shi Huang, implementing Legalist ideas to help Qin unify the realm. Legalism's coldness and efficiency reflected the brutal reality of an age where the strong devoured the weak.

Mohism's founder, Mozi (approximately 468-376 BCE), came from humble origins in the artisan class, and his teachings brimmed with grassroots wisdom and idealistic brilliance. Mozi proposed "impartial care," loving all people equally regardless of kinship or status; "opposing aggression," opposing aggressive warfare; "valuing the worthy," selecting talented individuals regardless of origin; and "frugality," opposing extravagance and waste. These principles, viewed through the lens of two thousand years later, still radiate humanitarian light.

What is even more astonishing is that Mohism demonstrated a remarkable scientific spirit. The Mojing contained primitive accounts of optics, mechanics, and geometry. Mozi discovered the principle of the pinhole camera and had preliminary understanding of the lever principle. Mohist disciples were skilled at crafting defensive weapons and repeatedly helped weak states resist powerful enemies' attacks. The story of Mozi traveling to Chu to prevent its attack on Song still moves readers today. Sadly, Mohism's scientific tradition nearly completely disappeared in later generations, one of the most regrettable losses in Chinese intellectual history.

Military Strategy and the Jixia Academy: Practical Wisdom and Academic Sanctums

The Spring and Autumn and Warring States period was an age of frequent warfare, so the emergence of military strategists was natural. Sun Wu (approximately 545-470 BCE), author of the Art of War, composed the oldest existing military theoretical work in the world, containing only six thousand characters yet encompassing strategy, tactics, intelligence, and diplomacy. Maxims such as "know yourself and know your enemy, and in a hundred battles you will never be defeated," "vanquish the enemy without fighting," and "warfare is the art of deception" have long transcended the military realm to become universally applicable wisdom. Napoleon reportedly read the Art of War after his defeat at Waterloo and lamented that had he read it earlier, he might not have lost. Today, the Art of War is translated into dozens of languages and widely used in business schools and military academies worldwide.

Speaking of the Hundred Schools of Thought, one cannot omit the Jixia Academy. This was a scholarly institution established by the state of Qi near the Jixia gate in its capital Linzi, existing from approximately 374 to 221 BCE, a span of about one hundred fifty years. The Jixia Academy can be called China's first "special zone of academic freedom." The Qi government provided scholars with generous treatment and elevated status while asking them to perform no administrative duties, only requiring them to freely pursue research, express opinions, and author works.

At the Jixia Academy, scholars from Confucianism, Daoism, Legalism, the School of Names, the School of Yin and Yang, and other traditions gathered together, freely debating and learning from one another. Mencius, Xunzi, Zou Yan, Tian Pian, Shen Dao, Chunyu Kun and other leading thinkers of the time had all lectured or studied there. According to records, during its heyday the academy had "hundreds of thousands" of scholars—something unprecedented in the world at the time. The Jixia Academy's existence was a concentrated manifestation of intellectual freedom in the Spring and Autumn and Warring States period. A government willing to spend enormous resources maintaining a group of scholars who performed no service to the state but merely engaged in free thought—this never happened again in subsequent Chinese history.

The End of Freedom: The Burning of Books and Persecution of Confucians

Yet inevitably, the golden age of thought came to an end.

In 221 BCE, Qin Shi Huang unified the six states and established China's first centralized unified empire. Unification brought political order but also intellectual suffocation. In 213 BCE, Minister Li Si memorialized the throne recommending the burning of privately held copies of the Book of Poetry, the Book of History, and the hundred schools, preserving only books on medicine, divination, and agriculture, with violators subjected to severe punishment. In 212 BCE, Qin Shi Huang executed over four hundred sixty scholars and Daoist magicians. Though the scale and brutality of the "Burning of Books and Persecution of Confucians" may be debated by historians, its message was unmistakable: the unified empire would not tolerate diverse intellectual views.

The Qin dynasty fell after only two generations, but the trend toward thought control did not reverse. Though the Early Han promoted the teachings of Huang and Lao, implementing non-action governance with relatively open intellectual conditions, by 134 BCE Emperor Wu of Han, accepting the advice of the great Confucian Dong Zhongshu, "banned the hundred schools and uniquely honored Confucianism," making Confucianism official orthodox thought. Subsequently, Confucianism merged with political power, civil service examinations based their content on Confucian classics, and scholars' intellectual space became confined within Confucian frameworks.

From then on, China never again witnessed the hundred flowers blooming and hundred schools contending as during the Spring and Autumn and Warring States period. Though every subsequent dynasty produced outstanding thinkers—Wang Chong's critical spirit, Wang Yangming's revolutionary mind-learning, Li Zhi's heretical defiance—they all represented repairs or breakthroughs within the Confucian framework rather than fundamental pluralistic competition. The situation where various schools engaged in equal dialogue and free debate, as in the Spring and Autumn and Warring States period, never returned.

Echoes from History: Why Is Freedom Precious?

The Hundred Schools of Thought of the Spring and Autumn and Warring States period impart a profound lesson: the flourishing of thought requires specific conditions—political multiplicity, the absence of overwhelming authority, hunger for talent, and tolerance of dissenting views. When these conditions existed, human intellectual creativity erupted explosively; when power reconcentrated and thought was channeled into unified tracks, creativity gradually withered.

What deserves deep reflection is that the Spring and Autumn and Warring States period coincided almost exactly with ancient Greece. When Confucius lectured in Lu, Socrates was debating in Athens; when Zhuangzi wandered freely through heaven and earth, Plato was constructing his Republic; when Mozi explored the principles of optics, Aristotle was organizing his encyclopedic knowledge system. The German philosopher Karl Jaspers called this period the "Axis Age"—human civilization virtually simultaneously, in different regions, underwent spiritual awakening.

Yet the subsequent historical trajectories diverged sharply. Greek intellectual traditions, transmitted through Rome and the Medieval period's tortuous paths, eventually reblossomed during the Renaissance, catalyzing modern science and democratic institutions. China's Hundred Schools of Thought, compressed into Confucianism's singular dominance after the Qin-Han unification, never recovered that era when stars brilliantly shone.

This is not to simplistically judge which path was better, but to remind us of something crucial: intellectual freedom is an extraordinarily fragile and precious thing. It does not exist naturally; it requires specific institutional environments to guarantee it. The brilliance of the Spring and Autumn and Warring States period testifies to the tremendous intellectual creativity of Chinese civilization, while the two thousand years of silence that followed cautions us that without institutional safeguards, even the most glorious intellectual traditions can be obscured by power. Looking back upon that age of brilliant stars, we are not merely paying tribute to our ancestors, but reflecting on the future: How can we ensure that the torch of thought never extinguishes?
