Neo-Confucianism vs. Yangmingism vs. Evidential Scholarship: Three Major Schools of East Asian Philosophy

When studying East Asian history, three major schools of thought inevitably appear: Neo-Confucianism, Yangmingism, and Evidential Scholarship.

Although their names may sound similar, their approaches to understanding the world are fundamentally different. Simply put, Neo-Confucianism emphasizes theory, Yangmingism emphasizes practice, and Evidential Scholarship emphasizes evidence.

Let’s compare them in simple terms.

1. The Biggest Difference: Where Is the Principle (理) of the Universe?

# Neo-Confucianism (Zhu Xi’s School)

“The principle exists in all things in the world and within human nature.” → Human Nature Is Principle (性卽理)

Zhu Xi believed that human nature itself embodies the universal principle (理).

# Yangmingism

“No. Principle exists only within the human mind.” → The Mind Is Principle (心卽理)

Wang Yangming argued that there is no principle that exists separately outside the mind. → Nothing Exists Outside the Mind (心外無物)

In other words, the ultimate standard of morality lies within one’s own mind.

2. How Should We Study?

# Neo-Confucianism

Neo-Confucianism placed great importance on the Investigation of Things and the Extension of Knowledge (格物致知).

It taught that people should expand their knowledge by thoroughly investigating the principles underlying things.

In other words, first comes knowledge (知), followed by practice (行). For this reason, Neo-Confucianism placed great emphasis on reading and studying the Confucian classics.

# Yangmingism

Yangmingism interpreted the Investigation of Things and the Extension of Knowledge (格物致知) in a completely different way.

It held that human beings are born with innate moral knowledge (良知), which enables them to distinguish between good and evil.

According to Yangmingism, studying does not simply mean reading many books. Rather, true learning means putting the innate moral knowledge within one’s own mind into practice.

3. What Is the Relationship Between Knowledge and Action?

# Neo-Confucianism

→ Knowledge and Action Should Advance Together (知行竝進)

Both knowledge and practice are important, but knowledge comes first and action follows.

This idea is known as “knowledge first, action afterward” (先知後行).

# Yangmingism

→ The Unity of Knowledge and Action (知行合一)

Wang Yangming explained it this way:

“Knowledge is the beginning of action, and action is the completion of knowledge.”

If you truly know something, you will inevitably put it into practice.

In other words, if you do not act on what you know, you have not truly understood it yet.

4. Why Did Yangmingism Emerge?

Over time, Neo-Confucianism became increasingly formalistic.

Scholars became preoccupied with ritual rules and textual interpretation, while paying insufficient attention to the everyday lives of ordinary people and pressing social problems.

Wang Yangming strongly criticized these tendencies.

He argued that “sages are not limited to scholars” and that “even ordinary people can become sages if they follow their own moral conscience.”

As a result, Yangmingism developed into a much more practical and action-oriented philosophy.

Compared with contemporary Joseon, Ming China was more open to commerce and trade and achieved greater socioeconomic development. This was not simply because of its larger territory and abundant resources. Another contributing factor was that Yangmingism, which developed in Ming China, had a stronger tendency to emphasize practical action and engagement with the real world than the Neo-Confucianism that dominated Joseon intellectual and political life.

During the Imjin War (Japanese invasions of Korea, 1592–1598), Ming officials such as Song Yingchang (宋應昌) and Yuan Huang (袁黃, Yuan Liaofan) sharply criticized Joseon for becoming excessively absorbed in the doctrinal principles and ideological orthodoxy of Zhu Xi’s Neo-Confucianism while neglecting practical military preparedness.

After experiencing the devastation of the Imjin War, some reform-minded intellectuals began to ask:

“Can Zhu Xi’s philosophy, with its emphasis on abstract theory, truly help improve people’s livelihoods and overcome a national crisis?”

Yangmingism was eventually introduced into Joseon as an intellectual alternative by such reform-minded scholars, contributing to the emergence of the Ganghwa School (江華學派).

However, many members of Joseon’s yangban scholar-official elite further reinforced Neo-Confucian orthodoxy and sought to impose the social hierarchy more strictly in order to protect their established privileges and avoid responsibility for the failures exposed by the war. Reform-minded scholars who embraced Yangmingism, including figures associated with the Ganghwa School, were denounced as “Samun Nanjeok” (斯文亂賊)—literally, “enemies who disrupt the orthodox Confucian tradition”—and faced political and intellectual persecution.

This contributed to political conditions that hindered practical reform and modernization in late Joseon and ultimately became one of the factors that weakened the dynasty in its final centuries.

In contrast, Japan adopted Yangmingism more pragmatically because its doctrine of the Unity of Knowledge and Action (知行合一) and its emphasis on decisive action were well suited to the martial ethos of the samurai warrior class.

Wang Yangming himself played an important role in giving Yangmingism this action-oriented character. He was not merely a philosopher but also an accomplished military commander and statesman. He famously suppressed the large-scale Prince of Ning Rebellion (寧王之亂) in just 35 days and conducted successful campaigns against armed groups and rebellions in southern China.

He developed much of his philosophy through practical experience while commanding armies and confronting life-and-death situations. Consequently, his collected teachings, the Instructions for Practical Living (Chuanxilu, 傳習錄), contain many practical and dynamic insights into leadership, politics, and action that could resonate strongly with people responsible for making decisions in the field. This practical and action-oriented dimension was one reason Yangmingism appealed to political and military elites in different parts of East Asia.

5. Evidential Scholarship: A Critique of Both Neo-Confucianism and Yangmingism

With the rise of the Qing dynasty, scholars began to raise a new set of questions:

“Aren’t both Neo-Confucianism and Yangmingism too preoccupied with abstract philosophical ideas?”

“The country has fallen—should we still be talking only about principle and the mind?”

Out of this intellectual climate emerged Evidential Scholarship (考證學).

Evidential Scholarship emphasized the rigorous examination of texts and historical evidence in order to establish verifiable facts.

6. The Core Spirit of Evidential Scholarship

# Seeking Truth from Facts (實事求是)

“Seek truth based on facts.”

Evidential scholars valued objective evidence over abstract philosophical speculation.

# Studying the Classics and Valuing Antiquity (讀書好古)

“Let us return to the original classics of Confucius and Mencius.”

Rather than relying on the interpretations of later scholars, they sought to understand the original texts themselves as accurately as possible.

7. How Did Evidential Scholars Conduct Research?

Evidential Scholarship was remarkably similar in some respects to modern historical and linguistic research.

Its major research methods included:

Philology and Exegesis — studying the original meanings of ancient words and characters

Historical Phonology — reconstructing ancient pronunciations

Epigraphy — studying inscriptions on stone monuments and bronze objects

Historical Geography — verifying whether geographical names mentioned in classical texts corresponded to actual locations

Astronomy — examining and verifying historical astronomical records

In other words, Evidential scholars analyzed vast amounts of material with the attitude:

“Do not accept claims without evidence.”

8. A Simple Comparison

# Neo-Confucianism

“Study the textbook carefully to understand the principles of the universe.”

→ Theory-centered

# Yangmingism

“Don’t just study—put what you know into practice right now.”

→ Practice-centered

# Evidential Scholarship

“Wait. Before we trust the textbook, let’s first check whether it is actually based on the original text.”

→ Evidence-centered

9. The Significance and Limitations of Evidential Scholarship

Evidential Scholarship greatly advanced the level of academic research by developing objective and evidence-based methods of inquiry.

These research methods also had a significant influence on Silhak (Practical Learning) in late Joseon Korea.

Prominent scholars such as Jeong Yak-yong and Kim Jeong-hui were influenced by Evidential Scholarship and conducted extensive research into history and epigraphy.

However, Evidential Scholarship also had its limitations.

At the time, the Qing dynasty severely suppressed intellectual and political criticism through the Literary Inquisition (文字獄). Even the slightest criticism of the imperial court or the ruling dynasty could result in severe punishment, sometimes extending to the scholar’s entire family or clan.

As a result, scholars had little choice but to avoid “dangerous subjects” such as political criticism and social reform in order to survive. Instead, they devoted themselves to relatively safe fields that were unlikely to provoke political controversy, such as studying ancient inscriptions on old stone monuments and analyzing the meanings of ancient characters.

Their techniques of textual verification and evidence-based research reached an extraordinarily sophisticated level, yet such scholarship did little to address the suffering of ordinary people or the growing crises facing the state.

This illustrates how, in a society where freedom of criticism and freedom of expression are severely restricted, even highly sophisticated scholarship can struggle to become a driving force for national development.

Ultimately, while the Qing dynasty suffered from mounting internal problems, it proved increasingly unable to respond effectively to the military, technological, and economic challenges posed by the Western powers.

In other words, the limitations of Evidential Scholarship demonstrate an important historical lesson:

“No matter how scientific and objective scholarship becomes, if freedom of thought and expression is suppressed, scholarship eventually loses its power to transform society and becomes isolated from the real world.”

10. What Drove the Development of the West During the Same Period?

Until the 18th century, East Asia and the West were broadly comparable in terms of economic scale and standards of living. Afterward, however, they followed increasingly different paths.

One of the crucial factors behind this divergence was the presence of greater intellectual freedom and the development of practical and applied scholarship in the West.

Intellectual Freedom: The Scientific Revolution vs. the Literary Inquisition

Scientists such as Galileo and Newton began to move beyond established religious doctrines and explain the laws of nature through mathematics, observation, and experimentation. The Enlightenment that followed further expanded the intellectual foundations for questioning political authority and traditional institutions.

In contrast, the Qing dynasty suppressed politically sensitive ideas through the Literary Inquisition, while Joseon also condemned scholars who challenged Neo-Confucian orthodoxy as “Samun Nanjeok” (斯文亂賊)—enemies of the orthodox Confucian tradition.

In a society where the freedom to criticize established authority disappears, it becomes much more difficult for thinkers capable of proposing entirely new paradigms to emerge and flourish.

The Purpose of Scholarship: Practical Technology vs. Textual Scholarship in the Ivory Tower

Many Western thinkers increasingly viewed knowledge as a tool for understanding and harnessing nature to improve human life. This intellectual orientation contributed to practical technological developments that eventually culminated in inventions such as the steam engine and the Industrial Revolution.

In contrast, scholarship in East Asia was often closely connected to the civil service examination system as a path to political office, as well as to personal moral cultivation.

Even Evidential Scholarship, despite its rigorous methodology, largely concentrated on textual and philological questions rather than developing technologies designed to transform the material world. Enormous intellectual resources were devoted, metaphorically speaking, to “finding errors in books written thousands of years ago.”

Structural Differences: Competitive Pluralism vs. a Vast Unified Empire

Europe consisted of numerous independent states competing intensely for political, military, and economic survival. When scholars or thinkers faced persecution in one country, they could sometimes flee to another and continue their work. This political fragmentation helped preserve alternative intellectual traditions and provided competing centers of scholarship.

In contrast, China was dominated for long periods by a vast centralized empire. When imperial authorities imposed ideological restrictions, there were fewer alternative political centers within China where dissident scholars could continue their work freely. China’s enormous cultural influence also meant that such intellectual trends could affect neighboring East Asian societies.

This structural environment could make the development and preservation of alternative intellectual traditions more difficult.

As a result of the global expansion of European power and the institutionalization of modern science from the 19th century onward, Western academic institutions and disciplinary frameworks became the dominant models used by universities and research institutes around the world today.

Most of the academic systems we encounter in elementary schools, secondary schools, and universities are organized according to frameworks heavily shaped by modern Western intellectual traditions.

The division of knowledge into broad areas such as the humanities, social sciences, and natural sciences, and their further subdivision into disciplines such as economics, sociology, political science, physics, and chemistry, largely developed through modern Western academic institutions.

Likewise, the modern degree system of Bachelor’s, Master’s, and doctoral degrees (Ph.D.), as well as practices such as dissertation examination, peer review, and publication in academic journals, developed primarily within European and later North American academic institutions.

Many specialized terms used today in East Asian academic and everyday language are also translations of concepts that originated or acquired their modern meanings in Western intellectual traditions.

As modernization accelerated in the late 19th century, Japanese and Chinese intellectuals began translating a vast range of Western concepts in philosophy, science, politics, and economics into Chinese-character terminology. Because so many unfamiliar concepts arrived within a relatively short period, new terms had to be coined or older terms had to be given new meanings.

Representative examples include:

Philosophy → 哲學 (철학 / zhexue / tetsugaku)

Society → 社會 (사회 / shehui / shakai)

Economy → 經濟 (경제 / jingji / keizai)

Science → 科學 (과학 / kexue / kagaku)

And these are only a few examples.

Many concepts that we now take for granted—including democracy, human rights, sovereignty, liberty, equality, the state, constitution, revolution, culture, and civilization—entered modern East Asian intellectual discourse through the translation and adaptation of Western political, social, and philosophical concepts.

Why Did East Asian Scholarship Not Become the Mainstream Foundation of Modern Academia?

“While many East Asian intellectuals of the past worked under restrictions on freedom of thought and expression and devoted enormous energy to the textual verification of ancient classics, European thinkers were increasingly questioning nature, experimenting, and constructing the foundations of modern science and academic disciplines. As Western institutions and scientific methods subsequently spread across the globe, modern East Asian societies came to understand and interpret much of the world through academic frameworks that were largely developed in the West.”
