“As an Unidentified Star to a Pilot”? Reclaiming the Common Good for Liberal Democracy.

In the messy reality of running a country, leaders constantly face a difficult question: who are they actually working for? For centuries, political thinkers have argued that a government's right to rule depends on its ability to serve the "common good." This is not a vague feeling of niceness, but a specific idea that a society has a shared interest in flourishing together, distinct from the simple sum of what each individual wants. However, in modern liberal democracies, where people hold many different beliefs and values, the idea of a single "common good" has become suspicious. Many experts worry that defining what is "good" for everyone inevitably leads to tyranny, where the majority crushes the minority or the state forces a specific way of life upon its citizens. Consequently, many democratic theorists have abandoned the concept, leaving a vacuum that populist movements on both the left and right have eagerly filled, claiming to speak for the true people while often ignoring individual rights.

This tension has created a crisis of trust. When citizens feel their leaders are no longer serving the collective interest, but rather chasing power or narrow agendas, the government loses its legitimacy. In this context, Alessandro Volpi, a researcher at the Max Planck Institute for Legal History and Legal Theory, asks a crucial question: is it possible to save the idea of the common good without sacrificing the freedoms that define a liberal democracy? The answer, Volpi suggests, is yes, but only if we change how we think about the concept. He argues that the common good does not need to be a fixed list of rules or a specific vision of the perfect life. Instead, it can be understood as a flexible guide that emerges from fair processes and protects the very structure that allows individuals to live freely.

Volpi's work builds a new model to show how these two seemingly opposing ideas—protecting individual rights and serving the collective good—can actually work together. He starts by acknowledging the deep fears that have kept democrats away from the common good. Critics argue that if a government claims to know what is best for everyone, it will inevitably become paternalistic, treating citizens like children who cannot choose for themselves. Others worry that the common good is just a disguise for the will of the majority, which could easily turn into a tyranny that ignores the rights of smaller groups. To solve this, Volpi proposes a system that acts like a safety valve. He suggests that the common good should be viewed primarily as a set of basic conditions that allow people to live and cooperate, rather than a specific destination they must all reach.

The core of his solution is a layered approach that prioritizes individual needs but allows for collective action when absolutely necessary. Imagine the common good as a set of three different tools that a government can use, but only in a specific order. The first and most important tool is the "instrumental" view, which focuses on providing the basic things everyone needs to survive and thrive, such as security, health, and the rule of law. This layer respects individual choices and ensures that the government is not forcing a specific lifestyle on anyone. The second tool is "aggregative," which simply adds up what people want. If a large group of people agrees on a policy that does not hurt anyone else, that policy can be part of the common good. This respects the democratic voice without overriding individual rights.

The third tool is the "organic" view, which treats the community as a whole entity that must be preserved. Volpi argues that this tool is dangerous if used all the time, because it can justify sacrificing individual rights for the sake of the group. However, he shows that it has a vital, limited role. In times of extreme emergency, such as a war or a natural disaster, the survival of the community itself becomes the priority. In these rare moments, the government may need to ask individuals to make sacrifices for the sake of the whole, because if the community collapses, no individual rights can exist anyway. Crucially, Volpi insists that this third layer only kicks in when the first two are not enough. By using a principle called "subsidiarity," which means using the smallest, most local solution possible before moving to a bigger one, the model ensures that the heavy hand of the collective is only used when absolutely necessary to protect the very conditions that make individual freedom possible.

To keep this system fair and open to all, Volpi proposes that the common good should be determined through a process of reasoned discussion rather than by a fixed set of rules. He envisions a scenario where leaders act as if they are listening to a perfect, fair conversation among all citizens. In this ideal conversation, people do not just argue for their own selfish interests; they try to find solutions that everyone could reasonably accept. This process does not require everyone to agree on everything, nor does it require a religious or philosophical belief in a single "truth." Instead, it relies on a shared commitment to fairness and the willingness to listen to others. This approach allows the common good to remain flexible and open to change, adapting to new challenges without becoming a rigid dogma that suppresses dissent.

The paper demonstrates that this model can withstand the usual attacks from liberal critics. It shows that the common good does not have to be a threat to individual rights; in fact, protecting the community's structure is often the only way to guarantee those rights in the first place. It also proves that the concept is not just a relic of the past or a tool for authoritarians. By defining the common good as a process rather than a fixed outcome, Volpi shows that it can serve as a standard for judging leaders. If a government claims to be serving the common good but ignores the voices of the people or fails to protect the basic conditions of life, citizens can use this very concept to challenge that government. This turns the common good from a weapon used by populists into a shield for democracy.

Volpi's findings suggest that liberal democracies do not need to throw away the idea of the common good to stay free. Instead, they need to reclaim it by defining it carefully. The research indicates that a government can claim to serve the people as a whole without becoming a dictator, provided it respects the priority of individual worth and only invokes the power of the collective in extreme circumstances. This approach offers a way out of the current political deadlock, where leaders often struggle to justify their authority. By grounding their power in a duty to serve a shared, evolving interest rather than a fixed ideology, leaders can regain the trust of their citizens. The study concludes that the common good is not a lost cause, but a necessary resource that, if understood correctly, can help liberal democracies navigate their current crises of legitimacy and reconnect with the people they are meant to serve.
