At first glance, “Boston public transportation” and “politics” seem entirely unrelated. Yet when brought together, they spark an unexpected chemical reaction.
The Green Line roars by, its mechanical groans echoing a century of weariness—staging, each day, a quiet moral experiment. The doors open, people stream in, and the card reader stands silently by. Most passengers ignore it. There are no turnstiles, no inspectors—fare evasion has become an unspoken social contract.
Boston’s public transportation mainly consists of rail and bus systems. The Green Line, part of the subway network, is divided into branches such as B, C, and D. The B branch connects Boston College and Government Center—my regular route this semester (why so often? because my bike got stolen). Part of the Green Line runs above ground, and part underground.
- On the surface sections, the system resembles a tram. Riders are supposed to tap their cards after boarding, but the rule depends entirely on honor. Drivers do not enforce payment, and as a result, most passengers choose not to pay; only a small fraction tap voluntarily.
- Once the train enters the underground portion, however, passengers must swipe their cards through turnstiles—supervision takes effect, and fare evasion becomes nearly impossible (New York, perhaps, being the exception).
- Buses occupy a middle ground: with the driver present, most passengers pay, though occasional small talk may earn someone tacit permission to skip the fare, or a gentle reminder to pay up.
It occurred to me that this system resembles a political allegory. The surface lines, buses, and underground gates symbolize three distinct modes of governance—rule by man, rule by law, and rule by technology. These are not simply sequential historical stages but coexist and interpenetrate in modern politics.
1. Moral Governance: The Collapse of the “Moral Community”
On the surface sections, whether one pays is left entirely to conscience. No barriers, no enforcement—everything rests on moral self-discipline. This is the essence of “rule by virtue”: order sustained by internalized ethics rather than external compulsion.
But such freedom depends on the existence of a moral community. Once individuals cease to believe that others will follow the rules, the chain of trust snaps—and the moral system collapses. Fare evasion becomes a rational choice, just as an unchecked official might see corruption as reasonable behavior.
The disorder above ground exposes the fatal flaw of moral governance: it requires broad mutual trust, something increasingly scarce in complex modern societies.
2. Rule of Law: The Bus and the Space Between Enforcement and Discretion
With the driver on board, the bus introduces a layer of supervision—symbolizing the early stage of the rule of law. There are rules, authority, and an enforcer. Yet there remains room for human discretion: the driver may show leniency, “understand” a passenger’s hardship, or overlook minor transgressions. This gray zone embodies the ethical ambiguity of discretionary power.
Political philosophy reminds us that the rule of law is not the elimination of humanity, but the constraint of arbitrariness.
The purpose of law is to make power predictable. When systems lack transparency and enforcement depends on personal relationships, power slips back into the realm of private will. “The rules exist—but they yield to relationships.” This, in essence, is why anti-corruption efforts so often fall short.
The bus thus represents a semi-institutional world: the system is present but relies on human agents; rules are strong but negotiable. It captures the central dilemma of governance—
how to balance humanity and legality, to make law neither heartless nor corruptible.
Rule of Technology: The Cold Order of the Underground Turnstile
The underground turnstile epitomizes the extreme form of institutional logic: the machine replaces humans as the executor of power. The gate shows no mercy and allows no exceptions—it enforces algorithmic justice, a justice without warmth. Every tap is logged, audited, and traceable—Foucault’s disciplinary power materialized in urban infrastructure.
Here, order is not maintained by punishment but by structure. People do not choose not to evade; they are structurally prevented from doing so. Individuals are woven into an invisible web of constraint; power operates through unseen systems. This technocratic form of control marks the peak of modern governance—and the onset of depersonalization. Power is absorbed by systems, responsibility translated into algorithms, and citizens become programmed into compliance.
This raises a deeper question: when systems become so perfect that trust is no longer necessary, do people still possess political agency? Or rather, can a perfect system coexist with human freedom?
Conclusion: Politics Behind the Turnstile
The Boston subway’s triple metaphor poses a fundamental question:
What kind of order do we wish to live in?
One based on trust and virtue? One governed by rational law? Or one secured by technological precision?
The ultimate goal of anti-corruption should not merely be a society without corruption, but one with agency—an order that restrains power while preserving human judgment, emotion, and freedom.
Otherwise, we may one day perfect an “underground turnstile society”— A flawless system, perhaps, but one that has erased the human touch.
Of course, rumor has it that fare inspectors might soon appear on the surface lines—but the rumor, as always, comes from those who graduated years ago. Perhaps that, too, is a kind of political technique.
