Excess is no better than deficiency.
過猶不及 (과유불급) means Excess is as bad as deficiency — in all things, the right balance is best.. temperance means The virtue of avoiding extremes and maintaining proper restraint and balance.. Two cultures point to the same truth in different languages.
The Meeting
In the 5th century BCE, in the state of Lu, the disciple Zigong asked Confucius, "Of Zizhang and Zixia, which is the better man?" Confucius answered, "Zizhang goes too far (過); Zixia falls short (不及)." Zigong asked again, "Then is Zizhang the better?" Confucius said, "過猶不及 — to go too far is the same as to fall short." Around the same time in ancient Greece, Aristotle was teaching that "every virtue lies in the mean (mesotes) between two extremes." The best is not at the extremes — the teachers of two civilizations left the same lesson.
The Eastern Story — A Single Word from Confucius
Gwayubulgeup comes from the words of Confucius (551–479 BCE) in chapter 16 of the "Xian Jin" book of the Analects. When the disciple Zigong (520–456 BCE) asked which of Zizhang and Zixia was superior, Confucius diagnosed that Zizhang "went too far" (過) and Zixia "fell short" (不及). Zizhang was gifted but excessively forward in character, while Zixia was diligent but passive. Naturally, Zigong asked, "Then is the excessive Zizhang not the better?" Confucius's answer became four characters that run through the history of East Asian thought — "過猶不及." The weight of this single phrase grew greater in later ages. The Doctrine of the Mean (Zhongyong), traditionally attributed to Confucius's grandson Zisi (483–402 BCE), systematized this principle, establishing "the mean" (中) — being without bias — and "the constant" (庸) — being unchanging — as the highest principles of Confucian ethics. The first chapter of the Doctrine of the Mean declares: "喜怒哀樂之未發, 謂之中; 發而皆中節, 謂之和" (Before joy, anger, sorrow, and pleasure arise, it is called the mean; when they arise and all hit the proper measure, it is called harmony). Gwayubulgeup is the most concise expression of this doctrine of the mean.
The Neo-Confucian scholars of Joseon interpreted gwayubulgeup as the harmony of "principle" (理) and "material force" (氣). Toegye Yi Hwang (1501–1570) held that both excess (過) and deficiency (不及) of emotion arise from the partiality of qi (氣). What is striking is that gwayubulgeup does not mean "permit deficiency." Confucius said that both deficiency and excess are bad; he did not say that deficiency is the lesser evil. One aims for the exact "mean" (中), while guarding equally against straying to either side.
The Western Root — The Art of Mixing in Due Proportion
The English "temperance" appeared in the mid-14th century. It came by way of the Old French "temperance" from the Latin "temperantia." The root is the verb "temperare" — "to mix in due proportion, to regulate, to moderate." From the same root come "temperature" (the proper state of heat), "temper" (disposition — the blending of character; and to temper steel — the regulation of hardness), and "temperate" (mild — a climate of the mean rather than the extreme). In ancient Greece, the corresponding concept was "sophrosyne." Aristotle (384–322 BCE), in the Nicomachean Ethics, argued that every virtue (arete) lies in the "mean" (mesotes) between two extremes. Courage is the mean between recklessness and cowardice; generosity is the mean between extravagance and stinginess. In this "Doctrine of the Mean," sophrosyne/temperantia was the virtue placed between pleasure and asceticism. Cicero translated it into the Latin temperantia and established it as one of the four cardinal virtues, and Thomas Aquinas, in the Summa Theologica, defined temperantia as "the virtue of regulating sensual pleasure by reason." According to the OED, the first English record is around 1340, used in the sense of "self-restraint, the mean that avoids extremes."
The truth the etymology reveals: temperance is not "enduring" but "mixing." The original meaning of temperare was to mix water with wine in the right amount, making it drinkable. Neither pure wine (excess) nor pure water (deficiency), but the well-mixed state, is best. It is exactly the same structure as the "mean" (中) of gwayubulgeup. Both traditions define the best not as "one of the extremes" but as "the blend between the extremes."

Oxford English Dictionary (OED)"temperance, n." OED Online. c. 1340, "moderation in action, thought, or feeling; self-restraint; the practice of restraining oneself from excess." From Anglo-Norman temperaunce, Old French temperance (12c.), from Latin temperantia "moderation, sobriety, discretion," from temperare "to mix correctly, regulate."

Online Etymology Dictionaryetymonline.com/word/temperance — mid-14c., "self-restraint, moderation," from Anglo-French temperaunce (mid-13c.), from Latin temperantia "moderation, sobriety, discretion, self-control," from temperans, present participle of temperare "to mix correctly, moderate, regulate" (see temper). Latin temperare originally meant "to mix in due proportions."
Shared Wisdom — The Optimal Point Between Extremes
Both "guard equally against both extremes." Gwayubulgeup declares excess (過) and deficiency (不及) to be "the same" (猶), and Aristotle's mesotes places excess (hyperbolē) and deficiency (elleipsis) as equal vices. Both traditions state clearly that one extreme is no better than the other.
Both use the image of "blending." The "mean" (中) of the Doctrine of the Mean is the center point biased toward neither side, and temperare is the mixing of two liquids in due proportion. Both languages see the best not as "one pure thing" but as "a balanced combination of several elements."
Both demand "practical judgment." Confucius's gwayubulgeup presupposes the wisdom to judge "where the mean lies" in each situation, and Aristotle's mesotes likewise requires the practical wisdom (phronesis) of "at the right time, toward the right object, to the right degree." The mean is not a fixed position but a dynamic balance to be readjusted at every moment.
The difference: gwayubulgeup is "descriptive" — a factual judgment that "excess is the same as deficiency." Temperance, by contrast, is "normative" — a directive for action: "be temperate." Confucius says "this is so," while Aristotle says "this is how it should be." Yet both approaches rest on the same understanding of humanity — that human beings are prone to drift toward the extremes.
Memory Anchor — One Line to Take Home
- ✓ 過猶不及 = excess (過) is, rather (猶), the same as falling short (不及). Both are failures.
- ✓ temperance = temperare (to mix in due proportion) -> the art of combining extremes in the right ratio, like wine and water.
- ✓ In one line: "A bow strung too tight will break; strung too loose, it cannot shoot."
"The best is not at the extremes. Balance itself is wisdom."
