Kenja ni wa hitokoto de juubun
Meaning of “賢者には一言で十分”
This proverb means that truly wise people have excellent comprehension abilities, so they can understand the essence of things with just a few words or brief explanations.
In other words, it expresses that for people with wisdom and insight, there’s no need for lengthy explanations—just conveying the key point in one word allows them to grasp the whole picture. This is also an expression used in situations where you trust and show respect for the other person’s understanding ability.
The reason for using this proverb is because you recognize the other person’s intelligence and experience. It contains feelings of trust, like “You would understand without me having to explain, wouldn’t you?” It also means respecting the other person’s time by conveying only the essential points concisely. In modern times, it’s often used in contexts like “I don’t need to explain in detail to you” when addressing excellent subordinates or colleagues. This saying contains deep insight into human intelligence—that truly wise people possess the power to infer the whole picture from fragmentary information and see through to the essence.
Origin and Etymology
Regarding the origin of this proverb, the theory that it’s rooted in ancient Chinese philosophical thought is generally accepted. It’s considered to have deep connections particularly with the thinking found in Confucius’s “Analects”—”A gentleman speaks little and values actions”—and with the teaching from Laozi’s “Tao Te Ching” that “Those who know do not speak; those who speak do not know.”
In Japan, from the Heian period through the Kamakura period, such Chinese philosophy spread widely along with Buddhist thought. The Zen concept of “mind-to-mind transmission” also shares common ground with the thinking behind this proverb. It’s the idea that the essence can be conveyed to people with true understanding ability without exhausting words.
Similar expressions can be found in moral instruction books from the Edo period, and it’s presumed to have developed in connection with the spirit of bushido. In Japanese society, which values a “culture of perception,” this proverb took particularly deep root. Even after the modernization process from the Meiji era onward, it has continued to be widely used as words expressing the value of concise and accurate communication. Even today, it’s inherited as the result of universal human observation that true wise people don’t need unnecessary explanations.
Usage Examples
- For Mr. Tanaka, detailed materials would be unnecessary—as they say, to wise person one word is sufficient
- She’s someone who truly embodies “to wise person one word is sufficient”—just convey the key points and she understands immediately
Modern Interpretation
In today’s information society, the meaning of this proverb has become more complex. Now that communication via SNS and email has become mainstream and short-text communication has become routine, the concept of “one word is sufficient” has taken on new meaning.
However, misunderstandings are also more likely to arise in modern society. Precisely because we live in an age of information overload, the ability to discern truly important points has become more crucial. Excellent businesspeople instantly grasp the core from vast amounts of materials and move their subordinates with concise instructions. This can truly be called the modern version of “to wise person one word is sufficient.”
On the other hand, with the spread of digital communication, there’s also the problem that context and emotions have become harder to convey. There’s also increased risk that “one word is sufficient” might be received as “insufficient explanation” or “cold treatment.”
With the arrival of the AI era, this proverb is gaining even newer interpretations. Excellent AI can execute complex tasks with minimal instructions, but in human-to-human communication, not only efficiency but also emotional consideration is necessary. Perhaps true wise people are those who can judge the appropriate amount of information according to their counterpart.
When AI Hears This
The human brain can only process a limited amount of information at once, known as psychologist George Miller’s discovery of the “Magical Number 7±2,” revealing clear limits to our working memory. From the perspective of cognitive load theory, the ancient wisdom that “a word to the wise is sufficient” aligns remarkably with cutting-edge neuroscience findings.
The reason wise people can “understand with just one word” isn’t simply because they’re smart. Through years of experience and learning, they’ve developed the ability to instantly “chunk” complex information. Just as chess masters can grasp an entire board position at a glance, wise individuals extract only the essential patterns from countless pieces of information, minimizing cognitive load while maximizing understanding.
In today’s world, the amount of information we process daily has increased dramatically, leaving many people suffering from “information fatigue.” Yet true sages can read the intent behind a brief comment more effectively than lengthy social media posts, and perceive the simple core truth better than verbose explanations.
In essence, wise people are “cognitive minimalists” who don’t waste mental resources and can utilize their brain’s processing power most efficiently. In our information-overloaded era, the value of this ancient wisdom becomes even more crystal clear.
Lessons for Today
What this proverb teaches us today is what true communication ability means. Precisely because we live in an age overflowing with information, the technique of trusting the other person’s understanding ability and conveying key points accurately has become important.
You too should try being conscious of how you communicate according to your counterpart in daily life. Subordinates and juniors might need careful explanations, but with experienced colleagues and superiors, concise reports might actually be more appreciated. Discerning the other person’s abilities and conveying information in appropriate amounts is also an expression of respect for them.
Also, why not aim to become someone who can “understand with one word” yourself? This doesn’t simply mean being quick-witted, but rather developing the power to perceive the other person’s position and situation, and the insight to see through to the essence from rich experience.
While modern society tends to emphasize efficiency, this proverb teaches us that true efficiency is built upon relationships of trust with others. Perhaps the most beautiful communication is the kind of relationship where we can understand each other.
