How to Read “What is written speaks for itself”
Kaita mono ga mono wo iu
Meaning of “What is written speaks for itself”
“What is written speaks for itself” means that documents and records play an important role as evidence.
Verbal promises and explanations can become unclear over time. Memories fade and interpretations differ.
But what is written down remains as objective proof.
This proverb is used when making contracts or agreements. It applies to situations where problems might arise later.
Examples include business contracts, meeting minutes at work, and loan agreements between individuals. The proverb emphasizes the importance of keeping written records.
Even today, business requires documentation, not just verbal promises. In legal procedures, written documents serve as decisive evidence.
Email and chat records also count as “what is written.” They become important materials when checking facts later.
Origin and Etymology
No clear literary record explains the origin of this proverb. However, it is deeply connected to the development of document culture in Japan.
Since ancient times, Japan has valued written contracts over verbal promises. During the Edo period, commerce flourished.
Documents like certificates and promissory notes gained legal power as proof of transactions. In merchant society back then, people said “one written character is worth more than a thousand gold pieces.”
This shows how much people recognized the importance of written records.
The expression “speaks for itself” originally means humans uttering words. Here, it represents documents making claims instead of people.
In other words, documents function as evidence. Human memory becomes vague. Verbal promises can change interpretation over time.
But written characters remain unchanged and continue to exist.
This proverb likely arose from trust in the objectivity and permanence of documents. When disputes occur, written records can clarify the facts.
This practical wisdom is condensed into these few words. It represents a practical lesson from ancestors in an era when written culture became society’s foundation.
Usage Examples
- We had a dispute about the contract terms, but what is written speaks for itself, so let’s check the contract properly
- Don’t just make a verbal promise—what is written speaks for itself, so please send it by email
Universal Wisdom
The proverb “What is written speaks for itself” contains deep insight into the uncertainty of human memory. It also addresses the disputes that arise from this uncertainty.
We all want to trust our own memories. But in reality, even among people who experienced the same event, memories gradually change over time.
Each person comes to hold a different “truth.”
This doesn’t mean anyone is lying. The human brain unconsciously reconstructs memories when storing experiences.
Emotions at the time and later experiences affect this process. This is why even well-meaning people argue about “you said” versus “you didn’t say.”
Our ancestors understood this fundamental human limitation. That’s why they recognized the value of objective records in writing.
What is written doesn’t change based on people’s emotions or convenience. It continues to testify quietly but surely about past promises and facts across time.
This proverb has been passed down for so long because it offers practical wisdom. It protects trust and fairness in human relationships.
Keeping records isn’t about doubting others. It’s also an act of kindness that compensates for our imperfect memories and prevents future misunderstandings.
When AI Hears This
Human spoken words are vibrations in air. From the moment they’re uttered, sound energy disperses into the surroundings.
This is what physics calls entropy increase—information scattering and becoming vague through natural flow. For example, when someone says “I’ll do it by next week,” the details blur over time.
Who said what, when, where, and how much? Memory in the human brain gets rewritten, and information continuously degrades.
But the moment something is written as text, information converts into physical structure. Ink arrangement on paper, magnetic patterns in digital data—it becomes fixed in a stable, low-entropy state.
This is a rare phenomenon in nature. Like life creating order, it’s an act of locally decreasing entropy.
What’s more interesting is that written information allows perfect copying. Oral transmission degrades information like the telephone game.
But documents preserve information quantity no matter how many times they’re copied. In information theory, this “irreversible recording” is considered the greatest invention in communication.
In other words, “what is written speaks for itself” because it’s the only weapon against time, our greatest enemy. The power to remain as evidence comes from physical laws themselves.
Lessons for Today
This proverb teaches us the value of always recording important matters. It’s not because we don’t trust others.
It’s kindness that helps each other’s memories and prevents future misunderstandings.
In work and personal life, make it a habit to confirm important promises and decisions by email or memo. This protects not only yourself but also your relationships with others.
It’s very sad when relationships break down later over “you said” versus “you didn’t say.”
Also, when you promise or decide something yourself, writing it down creates a sense of responsibility to yourself. The act of writing gives weight to words and makes us more sincere.
In today’s digital age, keeping records has become easier than ever. Use this convenience to develop the habit of recording important communications.
It’s a small but certain step that protects your future self and the people you care about.
