Confucius and the Ten Wings of the I Ching

Six centuries after King Wen, the I Ching was a revered but obscure text. Its hexagrams and their commentaries, written in archaic Chinese, remained enigmatically concise — a few words per line, a few sentences per figure. For court diviners, it was a working tool. For ordinary people, it was a sealed book.

It took one of the greatest minds in human history to break that seal. Confucius (Kong Qiu, 551-479 BCE) devoted the last decades of his life to studying the I Ching and wrote ten commentaries — the "Ten Wings" (Shi Yi) — that transformed a divination manual into a masterpiece of universal thought.

"If years were added to my life, I would give fifty to the study of the Yi, and might then avoid falling into great errors."
— Confucius, Analects (Lunyu), VII.16

This statement, recorded by Confucius's disciples, gives the measure of what the I Ching meant to him: not a pastime of old age, but the study of a lifetime — a text so profound that an extra half-century of study would not have been too much.

Confucius and the I Ching: a late and decisive encounter

Confucius was born in 551 BCE in the State of Lu (present-day Shandong province), six hundred years after King Wen and roughly four thousand five hundred years after Fuxi. He was contemporary with Lao Tzu — an extraordinary era when Chinese thought experienced an unprecedented flowering, the period known as the "Hundred Schools."

Philosopher, educator, politician disappointed by the corruption of his time, Confucius spent his life seeking the Way (Dao) — the path to harmony between people and with Heaven. He founded his thought on the study of ancient texts, which he considered repositories of the wisdom of the sage kings of antiquity.

Among these texts, the I Ching held a special place. Tradition reports that Confucius studied it with such intensity that the leather straps binding the bamboo strips of his copy broke three times (wei bian san jue). This expression, which has become proverbial in Chinese, still designates passionate and relentless study.

This is no mere anecdote. In Confucius's era, books were written on bamboo strips bound together by leather cords. To break those cords through use is to have leafed through the book hundreds, perhaps thousands of times. Confucius did not merely read the I Ching: he lived it.

Under the Han dynasty: the crystallization of the text

It was under the Han dynasty (206 BCE – 220 CE) that the I Ching took its definitive form, the one we know today. The Han made Confucianism the official doctrine of the empire and elevated the I Ching to the rank of first of the Five Classics (Wu Jing) — the founding texts of Chinese civilization.

It was at this time that the Ten Wings were formally integrated into the body of the text. The I Ching ceased to be a simple collection of oracular judgments and became a work in three layers:

• Layer 1 — The hexagrams and their judgments (attributed to King Wen, ~1100 BCE)
• Layer 2 — The commentaries on the six lines (attributed to the Duke of Zhou, ~1050 BCE)
• Layer 3 — The Ten Wings (attributed to Confucius, ~500-400 BCE)

The question of whether Confucius actually wrote the Ten Wings with his own hand has been the subject of scholarly debate for centuries. Some scholars believe the texts are the work of his disciples or later authors. Others maintain the traditional attribution. What is certain is that the Ten Wings bear the imprint of Confucian thought and would not have existed without the master's impetus.

The Ten Wings: ten commentaries to illuminate the obscure

Why "wings"? Because these ten appendices give the text the ability to soar — to leave the ground of raw divination and reach the heights of philosophy. Without the Ten Wings, the I Ching remains a collection of cryptic aphorisms. With them, it becomes a complete treatise on the nature of the universe and human conduct.

Here are the ten texts that make up the Shi Yi:

1 and 2. The Commentary on the Decision (Tuan Zhuan) — parts 1 and 2

The Tuan Zhuan comments on King Wen's judgments hexagram by hexagram. For each figure, it explains why the judgment says what it says — what is the internal logic of the hexagram, how the trigrams that compose it interact, and what this interaction means for the one who consults it.

This is a work of structural interpretation. Confucius (or his school) does not simply paraphrase King Wen. He unveils the mechanism: why does Heaven above the Lake produce a certain meaning? Why does Thunder below the Mountain generate a certain counsel? The Tuan Zhuan is divided into two parts, covering hexagrams 1 to 30 and 31 to 64 respectively.

3 and 4. The Commentary on the Images (Xiang Zhuan) — parts 1 and 2

The Xiang Zhuan is perhaps the most poetic of the Ten Wings. For each hexagram, it begins with an image drawn from nature — the combination of the two trigrams translated into landscape: "The wind blows over the earth," "Thunder sounds in the midst of the mountain," "Water flows above the fire."

From this image, it draws a moral lesson: "Thus the superior man..." followed by a counsel of conduct. It is here that the I Ching becomes explicitly an ethical guide. The Great Image (Da Xiang) comments on each hexagram as a whole, while the Small Image (Xiao Xiang) comments on each individual line.

Examples:

• Hexagram 1, Qian: "The movement of Heaven is full of power. Thus the superior man makes himself strong and untiring."
• Hexagram 2, Kun: "The state of the Earth is receptivity. Thus the superior man carries the outer world with breadth of virtue."
• Hexagram 15, Qian (Modesty): "In the midst of the earth, a mountain. Thus the superior man reduces what is in excess and increases what is in deficit. He weighs things and makes them equal."

5 and 6. The Great Appendix (Da Zhuan / Xi Ci) — parts 1 and 2

The Great Appendix (also called Xi Ci Zhuan, the "Commentary on the Appended Words") is the philosophical heart of the Ten Wings — and probably the most important text of the entire I Ching tradition after the hexagrams themselves.

It is here that Confucius takes the long view. He no longer comments on the hexagrams one by one: he expounds the general philosophy of the Book of Changes. He addresses:

• The nature of change — why everything is in perpetual mutation, and why this mutation is the fundamental law of the universe
• The history of the I Ching — how Fuxi created the trigrams, how King Wen combined them into hexagrams
• The method of consultation — the ritual of the yarrow stalks, the meaning of the numbers
• The role of the sage — how the superior man uses the I Ching to harmonize himself with the course of the world
• The relationship between words and images — how the symbols of the I Ching communicate what ordinary language cannot express

"The I Ching contains the measure of heaven and earth; that is why it enables one to embrace and put in order the Tao of heaven and earth. Looking upward, one observes the patterns of heaven; looking downward, one examines the laws of the earth."
— I Ching, Great Appendix (Xi Ci), part 1

The Great Appendix is the text that has most influenced subsequent Chinese philosophy. Such fundamental concepts as the Taiji (the Supreme Ultimate), the alternation of yin and yang as a cosmic principle, and the notion that "the I Ching is without thought, without action; silent and still, when stimulated it penetrates all situations under heaven" — all come from this text.

7. The Commentary on the Words (Wen Yan Zhuan)

The Wen Yan is an in-depth commentary reserved for the first two hexagrams — Qian (The Creative, Heaven) and Kun (The Receptive, Earth). These two hexagrams, composed respectively of six yang lines and six yin lines, are the "parents" of all the others. The Wen Yan explores their meaning with unmatched depth, detailing the virtues of the Creative (strength, elevation, perseverance, rightness) and those of the Receptive (devotion, openness, support, endurance).

8. The Commentary on the Sequence of Hexagrams (Xu Gua Zhuan)

The Xu Gua explains why the 64 hexagrams are arranged in their particular order — the famous "King Wen sequence." Each hexagram is linked to the previous one by a narrative logic: "After beings are created, they must be nourished" (hexagram 5, Waiting, follows hexagram 4, Youthful Folly). This text reveals that the sequence of the 64 hexagrams tells a story — the complete cycle of existence, from creation to completion.

9. The Commentary on Hexagrams in Opposition (Za Gua Zhuan)

The Za Gua is the briefest of the Ten Wings. It presents the hexagrams in pairs of opposites, summarizing each in one or two words. This extreme condensation is an exercise in clarity: "Qian is strong, Kun is yielding. Bi is joy, Shi is sorrow." It is a philosophical memory aid, a dazzling summary of the essential.

10. The Commentary on the Trigrams (Shuo Gua Zhuan)

The Shuo Gua returns to the foundations — Fuxi's eight trigrams — and explicates them in detail. It enumerates the attributes of each trigram: its qualities, the family members it represents, the animals, body parts, directions, seasons, and colors. It is the symbolic dictionary of the I Ching, the decryption key that allows one to understand how each trigram functions within each hexagram.

The transformation: from oracle to philosophy

The contribution of Confucius — or the Confucian school — to the I Ching is immense. Before the Ten Wings, the text was essentially an oracular tool. It was consulted to learn whether a military expedition would be favorable, whether a marriage would be happy, whether a harvest would be good. It was a divination manual, respected certainly, but confined to a utilitarian role.

The Ten Wings effected a metamorphosis. In commenting on the hexagrams, Confucius did not merely explain their divinatory meaning. He found — or projected — a complete philosophy of existence:

• A cosmology: the universe is a system of perpetual mutations, governed by the alternation of yin and yang
• An ethics: the superior man (junzi) harmonizes himself with the transformations rather than fighting them
• An epistemology: true knowledge comes through the observation of images and symbols, not through abstract reason alone
• A politics: good government imitates the order of the cosmos — the sovereign must be like Heaven, vast and impartial

Without the Ten Wings, the I Ching would have remained a collection of cryptic ideograms — fascinating for specialists, impenetrable for everyone else. It was Confucius who gave the text its words, its explanations, its breath. It was he who made it readable, thinkable, alive.

The legacy: the I Ching as foundation of Chinese thought

After Confucius, the I Ching was never merely an oracle again. It became the first of the Five Classics, the text that every Chinese scholar had to master. Its influence extended to every domain of Chinese culture:

• Traditional medicine — The meridian system and yin-yang diagnosis are directly derived from I Ching thinking
• Martial arts — Tai chi chuan takes its name from the Taiji (Supreme Ultimate) mentioned in the Great Appendix
• Feng shui — The art of spatial placement uses trigrams and hexagrams
• Military strategy — Sun Tzu's Art of War shares with the I Ching the vision of a constantly transforming world
• Art and calligraphy — The brushstroke echoes the yin and yang line

In the twentieth century, the I Ching crossed the borders of China to become a world text, thanks notably to Richard Wilhelm's translation (1923), prefaced by Carl Gustav Jung. But every time a Western reader opens the I Ching and understands what they read — every time the hexagrams cease to be hermetic symbols and become mirrors of the human condition — it is to the Ten Wings that they owe it. It is to Confucius that they owe it.

The old sage of Lu was right: fifty years of study would not have been too much. But thanks to his work, we do not need fifty years. He left us the wings.
