Mencius (Chinese: ; pinyin: Mng Zǐ; Wade-Giles: Meng Tzu), most accepted dates: 372 – 289 BCE; other possible dates: 385 – 303/302 BCE) was a Chinese philosopher who was arguably the most famous Confucian after Confucius himself.



Mencius, also known by his birth name Meng Ke or Ko, was born in the State of Zhou (; pinyin: zhōu cho; Wade-Giles: chou ch`ao; 372BC to 289BC), now forming the territory of the county-level city of Zoucheng (; originally Zouxian), Shandong province, only thirty kilometres (eighteen miles) south of Qufu, Confucius' birthplace.

He was an itinerant Chinese philosopher and sage, and one of the principal interpreters of Confucianism. Supposedly, he was a pupil of Confucius' grandson, Zisi. Like Confucius, according to legend, he travelled China for forty years to offer advice to rulers for reform.[5] He served as an official during the Warring States Period (403–221 BCE) in the State of Qi (; pinyin: q; 1046 BC to 221 BC) from 319 to 312 BCE. He expressed his filial devotion when he took an absence of three years from his official duties for Qi to mourn his mother's death. Disappointed at his failure to effect changes in his contemporary world, he retired from public life.

A Famous Idiom about Mencius' Early Life

The traditional Chinese four-character idiom (pinyin: mng mǔ sān qiān; Zhuyin/Bopomofo: ㄇㄥ ㄇㄨ ㄙㄢ ㄑ一ㄢ; Kana: もうぼさんせん; Romaji: mou bo san sen; literal translation: Mencius' mother, three moves) refers to the legend that Mencius' mother moved their house three times—from beside a cemetery to beside a marketplace, to finally beside a school—before finding a location that she felt was suitable for his upbringing. As an expression, the idiom refers to the importance of a proper environment for the proper upbringing of children.


Mencius' interpretation of Confucianism has generally been considered the orthodox version by subsequent Chinese philosophers, especially the Neo-Confucians of the Song dynasty. The Mencius (also spelled Mengzi or Meng-tzu), a book of his conversations with kings of the time, is one of the Four Books that Zhu Xi grouped as the core of orthodox Neo-Confucian thought. In contrast to the sayings of Confucius which are short and self-contained, the Mencius consists of long dialogues, including arguments, with extensive prose.

View on human nature

While Confucius himself did not explicitly focus on the subject of human nature, Mencius asserted the innate goodness of the individual, believing that it was society's influence – its lack of a positive cultivating influence – that caused bad moral character. "He who exerts his mind to the utmost knows his nature"[6] and "the way of learning is none other than finding the lost mind".[7]

His translator James Legge finds a close similarity between Mencius' views on human nature and those in Bishop Butler's Sermons on Human Nature.

The Four Beginnings

To show innate goodness, Mencius used the example of a child falling down a well. Witnesses of this event immediately feel

alarm and distress, not to gain friendship with the child's parents, nor to seek the praise of their neighbors and friends, nor because they dislike the reputation [of lack of humanity if they did not rescue the child]...

The feeling of commiseration is the beginning of humanity; the feeling of shame and dislike is the beginning of righteousness; the feeling of deference and compliance is the beginning of propriety; and the feeling of right and wrong is the beginning of wisdom.

Men have these Four Beginnings just as they have their four limbs. Having these Four Beginnings, but saying that they cannot develop them is to destroy themselves.[8]

View on politics

Mencius spoke frequently and highly of the well-field system.

Mencius emphasized the significance of the common citizens in the state. While Confucianism generally regards rulers highly, he argued that it is acceptable for the subjects to overthrow or even kill a ruler who ignores the people's needs and rules harshly. This is because a ruler who does not rule justly is no longer a true ruler. Speaking of the assassination of the wicked King Zhou of Shang, Mencius said, "I have merely heard of killing a dictator Zhou, but I have not heard of murdering [him as] the ruler."[9].

View on wars

He said during the Spring and Autumn Period, there's no Just war.

Comparisons to contemporaries

His alleged years make him contemporary with Xun Zi, Zhuangzi, Gaozi, and Plato.

Xun Zi

Xun Zi was a Confucian who believed that human nature is originally evil, and the purpose of moral cultivation is to develop our nature into goodness. Obviously, Mencius was at odds with him. His views were declared as unorthodox by Zhu Xi, and Mencius as orthodox.


Mencius is often compared to Plato for their theories on human nature. Both were idealists in that they believed in the innate moral goodness of all human beings.

Mencius' argument that unjust rulers may be overthrown is reminiscent of Socrates' argument in Book I of Plato's Republic.

Notes and references

  1. ^ The original clan name was Mengsun (孟孫), and was shortened into Meng (孟). It is unknown whether this occurred before or after Mencius's life.
  2. ^ Traditionally, his courtesy name was assumed to be Ziche (子車), sometimes incorrectly written as Ziyu (子輿) or Ziju (子居), but recent scholarly works show that these courtesy names appeared in the 3rd century CE and apply to another historical figure named Meng Ke who also lived in Chinese antiquity and was mistaken for Mencius.
  3. ^ That is, the second sage after Confucius. Name given in 1530 by Emperor Jiajing. In the two centuries before 1530, the posthumous name was "The Second Sage Duke of Zou" (鄒國亞聖公) which is still the name that can be seen carved in the Mencius ancestral temple in Zoucheng.
