American exceptionalism

 American Exceptionalism

Produced by Aubrey Lieberman with ChatGPT 5.0 turbo — September 2025

I was privileged to listen to a podcast conversation between the theoretical physicist Sean Carroll and the constitutional lawyer and thinker Cass Sunstein during September 2025. The essay that follows is my mnemonic—a way of organizing, remembering, and expanding upon the themes they touched, refracted through my own experience and curiosity.^1

Footnote 1

It was quite common for 19th-century political thinkers and public intellectuals to draw analogies from cosmology and astronomy, and nature. See Nicholas Campion, “Astronomy and Political Theory”(International Astronomical Union [IAU] Proceedings, 2011).

Liberalism can be imagined as a field, one created by humans rather than discovered in nature, yet bearing structural resemblances to the physical fields that make the universe possible. Uncertainty is its defining characteristic, not a flaw but a fundamental property, much as quantum indeterminacy is woven into the fabric of matter itself.

In this field, individual freedom plays the role of conceptual space-time. It is the medium in which social and political life can unfold, the dimensional backdrop against which human choice and action acquire meaning. Without freedom, there is no arena for thought or debate, no stage upon which life in common can take shape.

But freedom alone is insubstantial. Just as the Higgs field endows particles with mass, liberal societies require core commitments—rule of law, tolerance, equality before the law—to give liberty weight and coherence. Without them, liberty would drift into abstraction, a weightless concept unable to anchor civic reality.

Gravity, in this analogy, is responsibility. In physics, gravity curves space-time so that matter and energy trace coherent paths. In liberal politics, responsibility prevents freedom from flying apart into chaos. The force of responsibility—shaped by the imperative not to harm others and to promote the common good—curves liberty into durable orbits. Without this gravitational pull, liberal societies disintegrate, consumed by the collisions of unchecked freedom.

The American experiment is the boldest attempt to amplify and stabilize this liberal field. From its founding, the United States wagered that liberty could serve as the very space-time of a nation. The Declaration of Independence reads like a field equation: asserting intrinsic rights, establishing liberty as the medium of political life, and committing to a framework strong enough to sustain it. The Constitution followed as the Higgs mechanism of American politics, giving liberty weight through law, structure, and balance.

As Margaret Thatcher put it in a 1991 address at the Hoover Institution: “The European nations are … the product of history and not of philosophy. You can construct a nation on an idea; but you cannot reconstruct a nation on the basis of one.” She was capturing in striking terms the sense that the United States is different — that it was founded not on inherited monarchy or ethnic tradition, but on abstract principles of liberty and law.

Yet this statement also reveals an omission. The founding generation of Americans saw themselves as beginning anew, as if on a blank canvas. But North America was not empty. It carried the histories of many thousands of years of Indigenous life — cultures with their own philosophies, laws, and social systems — which were displaced, marginalized, or erased in the creation of the new nation. To say that America was “constructed on an idea” is true in one sense, but it also overlooks the deeper human past on which that construction took place.

Moreover, the founders did not create their political philosophy in isolation. They encountered Native American leaders whose traditions of governance, consensus-building, and confederation provided powerful examples of how liberty and responsibility could be structured in a diverse society. The Iroquois Confederacy in particular influenced debates about federal union and representation. Benjamin Franklin himself pointed to the Iroquois model as evidence that diverse communities could unite under common rules without erasing their autonomy. This wisdom, though rarely acknowledged in the canonical story, was also incorporated into the philosophy of the new nation.

America’s history also reveals the turbulence of such a field. Slavery and segregation, exclusion and inequality, testify to the destructive force of liberty when insufficiently curved by responsibility. The Civil War nearly collapsed the field entirely, a moment when competing trajectories of freedom threatened to annihilate one another. Reconstruction, the civil rights movement, and ongoing struggles for equality can be understood as recalibrations of the gravitational constant: repeated attempts to bring liberty back into orbit around justice.

America’s history of slavery and segregation invites comparison with my country of origin, South Africa. There, too, lofty principles of justice and freedom were betrayed by a system of entrenched inequality. Nelson Mandela’s Long Walk to Freedom recounts both the brutality of apartheid and the resilience of a movement determined to realize universal dignity. Alan Paton’s Cry, the Beloved Country, written decades earlier, gave prophetic voice to the moral crisis that apartheid represented. The lesson is sobering: when a nation discards its guiding liberal principles, it courts ruin.

This theme of moral tension also echoes in my Jewish background and in the six months I lived in Israel in 1971. Abba Eban, himself born in South Africa, wrote powerfully in My People: The Story of the Jewsabout the paradox of establishing a nation in a place already inhabited. His reflections echo the tension between philosophy and history that Margaret Thatcher invoked: ideas can give a nation coherence, but they do not erase the deeper histories of those who lived on the land before. In South Africa, Israel, and North America, the creation of a new political order required confronting — or too often ignoring — the long presence of others. That moral complexity continues to shape the meaning of exceptionalism, reminding us that no nation begins on a blank slate.

American exceptionalism is thus not an exemption from the laws of history, but a demonstration of them. Out of uncertainty and fluctuation, structure can emerge. Out of possibility, durable order can be created and renewed. The United States remains exceptional not because it transcends these forces, but because it embodies them—because its history shows, with all the turbulence of the universe itself, that freedom, substance, and responsibility can together generate a field strong enough to hold a people in common.

Alexis de Tocqueville, writing in the 1830s, observed that the United States had achieved something remarkable: a society that combined liberty with equality in ways unseen in Europe. He recognized that America’s experiment was fragile, but also that its strength lay in habits of association, civic participation, and a shared belief in self-government. Unlike Europe’s hierarchical traditions, the United States was animated by the principle that status was not fixed but open. Land, opportunity, and the absence of entrenched aristocracy gave American democracy its restless energy. Tocqueville warned, however, that this same equality could lead to conformity, mediocrity, and even tyranny of the majority if not balanced by institutions and cultural restraints. His insights foreshadow the recurring tension in American history: liberty versus order, individual versus community, equality versus excellence.

American exceptionalism has always been contested ground between liberal and conservative visions. Liberals often see exceptionalism as the promise of universal rights and democratic expansion: the idea that America’s mission is to broaden freedom, both at home and abroad. Conservatives, in turn, emphasize America’s unique traditions, cultural inheritance, and the importance of restraining government to protect individual initiative. George Will exemplifies a distinctly American conservatism that, paradoxically, grew from liberal soil. Though often labeled a conservative, Will’s philosophy is liberal in the older sense: it is rooted in the Enlightenment ideals of limited government, ordered liberty, and skepticism of state power. In that sense, conservatism in America is itself a liberal project—a defense of the liberal field against overreach or collapse.

John Rawls, by contrast, advanced a philosophical liberalism centered on justice as fairness. His thought experiment—the veil of ignorance—asked citizens to design a just society without knowing their own place in it. This framework emphasizes equality of opportunity and the protection of the least advantaged. Rawls represents the gravitational force of responsibility: the insistence that liberty must be curved toward justice to remain stable.

The 20th century tested American exceptionalism through depression, world war, and cold war. Franklin Roosevelt’s New Deal expanded the state’s role to secure economic rights, embodying a Rawlsian gravity that sought to stabilize liberty through social welfare. Ronald Reagan later revived the language of exceptionalism as a celebration of freedom, entrepreneurship, and America’s mission as a shining city on a hill (a reference to the biblical Jerusalem). The tension between these visions continues. In the 21st century, exceptionalism is fractured between those who view America as a universal model of democracy and those who fear that universalism dilutes America’s particular traditions. The polarization of recent decades reflects the instability of the field: competing trajectories of freedom, equality, responsibility, and identity.

To speak of American exceptionalism is not to suggest that the United States is immune from failure, nor that it is uniquely virtuous. Rather, it is to recognize the peculiar intensity of its experiment: to construct a society where freedom is the medium, law the mass-giving Higgs, and responsibility the gravitational pull. The United States is exceptional because it continues to test whether such a field can endure. Its success or failure matters not just to its citizens, but to the world that watches whether possibility can again and again give rise to durable order.
