Jeong Yak-yong and the Mokminsimseo: The Radical Duty of Governing for the Governed
A Question Nobody Dares to Reverse
We are accustomed to asking whether citizens trust their government. Transparency International’s 2025 Corruption Perceptions Index records a global average of just 42 out of 100, with 122 countries scoring below the midpoint. The OECD reports that only 39 percent of citizens across surveyed nations express high or moderately high trust in their national government. The diagnosis is always the same: public trust is eroding. But notice the direction of the question. It asks whether the people believe in their rulers. It never asks whether the rulers have earned the right to govern the people at all.
Two centuries ago, a Korean thinker exiled to the edge of his nation reversed precisely this question — and the answer he produced remains one of the most devastating critiques of public power ever written.
The Exile Who Saw What Courts Could Not
Jeong Yak-yong (1762–1836), known by his pen name Dasan, was among the most formidable intellects of the late Joseon dynasty. A proponent of silhak — practical learning — he had served in government and designed engineering works, including the construction crane for the Hwaseong Fortress. Then, in 1801, the Sinyu Persecution swept through the court. Jeong’s Catholic connections became a political weapon. He was stripped of everything and sent to Gangjin, a remote southern county, where he would remain for eighteen years.
It was during this exile, surrounded not by courtiers but by impoverished peasants ground down by corrupt local magistrates, that Jeong completed his masterwork. The Mokminsimseo (牧民心書) — literally, “The Mind of Shepherding the People” — was finished in 1818, comprising forty-eight volumes organized into twelve sections and seventy-two articles. Every article addressed the concrete duties of a local governor, from the moment of appointment to the day of departure. This was not abstract political philosophy; it was an operational manual for ethical governance, written by a man who had witnessed the consequences of its absence at the closest possible range.
The Inversion That Changes Everything
In his shorter essay Wonmok (原牧, “On the Origin of Governance”), Jeong posed a question so simple that it becomes explosive: does the governor exist for the people, or do the people exist for the governor? His answer was unequivocal — the governor exists for the people. This was not sentimentality. It was a structural argument: the office itself has no legitimacy except as an instrument of the people’s welfare.
The Mokminsimseo translates this principle into relentless specificity. Its governing concept is gongnyeom (公廉) — a compound of fairness and integrity. Jeong wrote: “One must be frugal to be incorruptible, and incorruptible to love the people. Therefore, frugality is the first thing a governor must practice.” Notice the logical chain: personal discipline is not an end in itself but a precondition for structural justice. Integrity without public consequence is mere vanity; public service without personal discipline is mere theater.
What makes this framework devastating is its refusal to separate moral character from institutional performance. Modern governance tends to isolate these domains: personal ethics belongs to the individual, systemic failure belongs to institutions. Jeong dismantled this partition. When a magistrate enriches himself, he does not merely commit a private sin; he breaks the very mechanism through which the state meets its obligation to the governed. The corruption of a single official is, in Jeong’s architecture, a structural event.
When the Shepherd Becomes the Wolf
This insight cuts directly into our present condition. The global erosion of public trust is routinely treated as a crisis of communication — as though better messaging or more transparent dashboards could restore faith. Jeong would have recognized this maneuver as a deflection. The problem is not that citizens fail to understand their governments; it is that governments have failed to embody the principle for which they exist. When public offices become instruments of private accumulation, when regulatory agencies serve the industries they were created to restrain, the shepherd has become the wolf, and no quantity of wool can disguise the teeth.
Yet Jeong’s framework carries a tension worth preserving. He did not imagine that structural reform alone could produce ethical governance. Without the inner discipline of gongnyeom, institutions become hollow shells. At the same time, individual virtue without institutional accountability devolves into mere posturing. The Mokminsimseo insists on both, simultaneously — a demand as uncomfortable for progressives who trust only in systems as it is for conservatives who trust only in character.
Reclaiming the Right to Demand
If Jeong’s reversal holds — that the governed do not exist for the governors but the other way around — then citizens possess not merely the right to trust or distrust, but the right to demand. This is not a passive right. It requires the same discipline Jeong demanded of officials: the willingness to study how governance actually works, to refuse seductive simplicities, and to hold power accountable with specificity rather than spectacle. Community oversight boards, participatory budgeting, civic literacy programs — these are modern echoes of the Mokminsimseo’s insistence that governance is too important to be left to governors alone.
Two hundred years after its completion, Jeong’s exile text reminds us that the health of a polity is measured not by the loyalty of its subjects but by the accountability of its servants.
The question Jeong Yak-yong asked from his exile hut still waits for an honest answer: does the office serve the people, or have the people learned to serve the office?
In your own encounters with public power — at a district office, a courtroom, a city council — when did you last feel that the person behind the desk existed for your sake?
