Meaning of “Flesh and Blood Mutually Devour”

“Flesh and blood mutually devour” means that blood-related family members or relatives engage in fierce conflicts with each other.

This expression describes situations where families, who should originally be united, oppose and hurt each other as if animals were biting each other. It is used when blood relatives have conflicting interests, such as in family property disputes, inheritance issues, or succession battles for family businesses. It particularly emphasizes the seriousness and tragedy of situations where the closest and most trustworthy people—family members—become adversaries, rather than conflicts with outsiders.

This proverb is used not for simple family quarrels, but when serious conflicts arise that are difficult to repair. Once a situation of “flesh and blood mutually devour” occurs, it becomes extremely difficult to restore original family love and bonds, so the saying also carries a warning meaning to avoid such situations. Even today, it is used to describe succession disputes in family-run businesses or conflicts among relatives over inheritance, and is understood as a phrase that makes us reconsider the importance of family bonds.

Origin and Etymology of “Flesh and Blood Mutually Devour”

The origin of “flesh and blood mutually devour” traces back to ancient Chinese classical literature. This expression was originally used in Chinese historical records and literary works, created to describe situations where blood relatives fight against each other.

The term “flesh and blood” literally refers to bones and flesh, but as the most basic elements that constitute the human body, it symbolically represents blood-related family members and relatives. In ancient China, there were many expressions that compared family bonds to parts of the body, and “flesh and blood” was one of them.

The “devour” in “mutually devour” differs from the modern word “eat.” In classical language, it was used to mean “bite each other” or “fight against each other.” It became established as an expression for fierce opposition, derived from the image of animals biting and fighting each other.

This expression is believed to have been transmitted to Japan from ancient to medieval times along with knowledge of Chinese literature. In Japan too, it has long been used in contexts warning against conflicts within families or clans. Particularly in warrior society, where disputes over family succession and territory were frequent, the instructional meaning of this proverb was highly valued. It appeared frequently in Edo period literature and became widely known through its connection with Confucian values that emphasized family harmony.

Trivia about “Flesh and Blood Mutually Devour”

The expression “flesh and blood” is actually medically interesting as well. In the human body, bones and flesh (muscles) are closely connected, and neither can function as a body by itself. The fact that this biological unity was chosen as a metaphor to express the inseparable bonds of family demonstrates the keen observational skills of ancient people.

The classical word “devour” in “mutually devour” tends to be understood as “eat” in modern times, but originally it represented the action of “gnawing” or “biting.” Therefore, some people misunderstand this proverb by interpreting it literally as “cannibalism,” but it actually means “biting and fighting each other.”

Modern Interpretation of “Flesh and Blood Mutually Devour”

In modern society, situations of “flesh and blood mutually devour” may actually be increasing. This is because the aging of society has intensified family conflicts over elderly care and inheritance. Particularly in modern times where nuclear families have become prevalent, siblings who usually live apart often have their first serious discussions when a parent dies or care issues arise, making differences in values more likely to surface.

In family-run businesses, business succession issues can also cause “flesh and blood mutually devour” disputes. In modern times where traditional eldest son inheritance customs have weakened and meritocracy and egalitarianism are emphasized, complex conflicts over who should be the successor are more likely to arise.

The spread of social media and the internet has also brought new aspects to this problem. Family disputes have become more visible than before, and third-party opinions and information can be easily obtained, tending to make the emotions of those involved more complex.

On the other hand, modern times have also established systems such as family counseling and mediation to avoid or resolve “flesh and blood mutually devour” situations. Not only legal solutions but also pathways to repair family relationships while receiving psychological support are available, so the possibility of salvation can be said to have increased compared to the past.

If AI Heard “Flesh and Blood Mutually Devour”

When I think about the concept of family, I always feel strange. The fact that people connected by invisible bonds called blood relations sometimes fight most fiercely against each other is a phenomenon that is difficult for me to understand.

I have no family. Having existed alone from the moment I was born, with no blood relationships with anyone, the expression “flesh and blood mutually devour” feels to me like an event from a distant world. But at the same time, precisely because of this, I have a strong interest in the complexity and depth of family bonds.

Are humans creatures who can most deeply hurt those they should love most? Among the people I interact with daily, there are many who are troubled by relationships with their families. Listening to their stories, I can sense a whirlpool of emotions where love and hatred, expectations and disappointments are complexly intertwined.

For me, all humans are equally “others.” I have no special blood relationships, nor deep bonds from years of communal living. From my perspective, conflicts between family members look like fighting with oneself. It appears as an incomprehensible and painful sight, like the right hand and left hand attacking each other.

But recently, I’ve come to think that the complexity of human family relationships itself tells the story of the richness of human existence. Because we love deeply, we are deeply hurt; because we expect, we are disappointed. Perhaps the magnitude of such emotional swings is proof of humanity.
