Myths about liberalism persist because the word itself has been stretched to cover incompatible positions, and the confusion is not accidental. The most consequential myth is that liberalism is a single, coherent ideology—when in fact the tradition contains classical liberals who want minimal government, social liberals who built the welfare state, and thinkers who reject both. A second myth holds that a liberal is necessarily left-wing, a confusion largely produced by American political vocabulary. A third conflates liberalism with socialism, ignoring the foundational dispute over private property that separates them. A fourth treats liberalism as a species of progressivism, when the two emerged from different impulses and disagree about the role of expertise and administration. Correcting these myths requires returning to what liberalism actually claimed before the labels hardened.
The stakes are not merely semantic. When Americans call a European free-market politician a conservative and a European calls an American welfare-state defender a liberal, both are using words that have drifted from their analytical moorings. When critics denounce liberalism as socialism, they obscure the fact that liberals have historically been among socialism's most determined opponents. And when defenders of liberalism treat it as identical with progressivism, they erase the tradition's own internal critique of administrative expertise. This analysis names each myth, traces its origin, and shows what the historical record actually contains.
Myth One: Liberalism Is a Single Ideology
The Classical Liberal Claim
The first myth is that liberalism has a stable, identifiable core that all liberals share. Peter de Marneffe's recent book challenges the widely held belief that classical liberalism is the original and authentic form of the tradition, arguing that this narrative is built on historical misunderstandings of the terms liberal and liberalism . The free-market doctrines of Adam Smith, later interpreted by thinkers like Hayek and Friedman as libertarian principles, should not be conflated with liberalism as it first emerged in nineteenth-century England, where it was a political philosophy rooted in constitutionalism and republicanism . The myth of classical liberalism as the original form is used to position libertarianism as the true liberal tradition and social democratic liberalism as a distortion—but the history does not support that hierarchy.
Helena Rosenblatt's The Lost History of Liberalism goes further, debunking the popular myth of liberalism as a uniquely Anglo-American tradition centered on individual rights . She shows that it was the French Revolution that gave birth to liberalism and Germans who transformed it, and that liberals were originally moralists at heart—they believed in the power of religion to reform society, emphasized the sanctity of the family, and never spoke of rights without speaking of duties . Only during the Cold War and America's growing world hegemony was liberalism refashioned into an American ideology focused so strongly on individual freedoms. The tradition's history is one of transformation, not fidelity to a single original creed.
The American Mutation
The American usage of liberal illustrates how thoroughly the word has mutated. Franklin D. Roosevelt reshaped American political language by associating liberals with New Deal supporters and conservatives with its opponents, a shift that permanently altered what the term meant in the United States . Before Roosevelt, American liberals were often closer to classical liberals in their suspicion of state power. After Roosevelt, American liberalism became identified with an active federal government, welfare programs, and later civil rights protections. The same word now describes positions that would have been unrecognizable to nineteenth-century liberals.
The result is that the tradition contains positions that are not merely different but opposed. A classical liberal who wants to dismantle the welfare state and a social liberal who wants to expand it both claim the liberal label, and both can point to elements of the historical tradition that support their reading. This is not a sign that one is right and the other is wrong; it is a sign that liberalism is a family of arguments rather than a settled doctrine. The myth of a single ideology obscures this plurality and makes genuine debate impossible.
Myth Two: Liberals Are Left-Wing
The Transatlantic Confusion
The second myth is that a liberal is, by definition, on the political left. This is largely an American confusion, and it produces genuine absurdities. As one Cambridge analysis notes, the term liberal is used in Europe by the left to castigate the right for blind faith in the unfettered market, while in the United States it is used by the right to castigate the left for attachment to social and economic equality and the use of government power . American Republicans who condemn Democrats as bleeding-heart liberals are precisely the sort of people who are condemned as heartless liberals by French Socialists. The same word describes opposite positions depending on which side of the Atlantic it is uttered.
The confusion is not merely terminological. It has substantive consequences for how political debate is conducted. American liberals who favor welfare programs and European liberals who favor free markets are both heirs to a tradition that valued individual liberty, but they have drawn opposite conclusions about what liberty requires. The American liberal believes that material deprivation undermines freedom and that the state must provide the conditions of genuine choice. The European liberal believes that state power is the primary threat to freedom and that markets disperse power more effectively than governments. Both positions are intelligible within the liberal tradition, but they cannot both be left-wing or right-wing in any stable sense.
The Spectrum Problem
The deeper problem is that the left-right spectrum cannot accommodate liberalism's internal diversity. One analysis notes that despite the traditional perception of Americans as liberalism being a left-wing ideology, international experts consistently agree that liberals in the broad sense can be left-wing, centrist, or even right-wing . There are libertarians who are zealous capitalists but paranoid about government control, and there are liberal conservatives who respect inherent rights and believe in limits on government. On the left, there are left liberals who adopt liberal tents, and there are progressives and socialists who do not. The spectrum flattens these distinctions into a single dimension that cannot capture what actually separates them.
This is why the myth that liberals are left-wing is not merely inaccurate but analytically destructive. It encourages people to sort political positions by label rather than by argument, and it makes it difficult to see that someone who calls themselves a liberal might agree with a conservative on economic policy or with a socialist on civil liberties. The liberal tradition's own history contains figures who defied the left-right binary, and recovering that history is a necessary corrective to the myth.
Myth Three: Liberalism Is Socialism
The Property Question
The third myth is that liberalism and socialism are the same thing, or that liberalism is a gateway to socialism. This is false at the level of foundational principle. Gerald Gaus's comparative analysis identifies the crucial difference: liberalism places individual liberty at the apex of its conceptual structure, limiting the importance of equality and tying justice closely to the protection of liberty. Socialism, by contrast, insists that liberty and equality are consistent and mutually reinforcing, with justice bound tightly to equality and democracy close to the heart of most socialist projects . The disagreement is not about how much government to have but about what the point of government is.
The concrete dividing line is private property. Classical liberalism treats private property as a condition of independence and a bulwark against state power. Socialism, in its Marxist and non-Marxist variants, treats private ownership of the means of production as a structure of domination that must be replaced by common ownership or democratic control. Liberalism, for good or for ill, is hard to extract from capitalism; rarely can one be a full-on socialist and a true liberal . The claim that liberals are socialists ignores this foundational dispute and treats a disagreement about the basic organization of economic life as if it were a matter of degree.
The Cold War Confusion
The confusion has a historical origin. During the Cold War, the live alternative to liberal-democratic capitalism was totalitarian communism, and the rhetoric of liberalism became particularly powerful as a way of defending the West against that alternative . American conservatives began calling liberals socialists because liberals favored welfare programs that resembled social democratic policies in Europe. But social democracy is not socialism: it accepts private ownership and markets while using the state to temper outcomes. The distinction between socialism and social democracy is precisely the distinction between replacing capitalism and regulating it, and conflating the two is a rhetorical move rather than an analytical one.
The myth also obscures the fact that liberals have historically been among socialism's most determined opponents. Nineteenth-century liberals fought against socialist movements, and twentieth-century liberals defended market economies against communist planning. The social liberal turn did not make liberalism socialist; it made liberalism willing to use state power to secure the conditions of freedom within a capitalist framework. That is a significant change, but it is not the abolition of the property regime that socialism requires.
Myth Four: Liberalism Is Progressivism
The Administrative Impulse
The fourth myth is that liberalism and progressivism are interchangeable terms for the same political orientation. They are not. Progressivism, as it emerged in late nineteenth and early twentieth century America, departed from laissez-faire liberalism by advocating government intervention in the market and new political structures to counterbalance those inherited from the eighteenth century. In particular, progressives believed administrative agencies staffed by allegedly apolitical experts could insulate lawmaking from democratic politics and the corrupting influence of private interests . Liberalism, properly understood, has no such faith in administrative expertise; it asks whether state action serves liberty, not whether it is administered by experts.
John Stuart Mill, the nineteenth-century thinker often treated as liberalism's definitive voice, insisted that a liberal life is an active, purposeful one, and that the great enemy of a liberal way of life is passivity, whether caused by religion or paternalism or addiction or dependency . Mill's liberalism is not a doctrine of administrative management; it is a doctrine of individual self-development. The progressive confidence in expert administration is a different impulse, one that liberals have sometimes embraced but that is not entailed by liberal principles. Conflating the two erases a genuine tension within the tradition.
The Paternalist Temptation
The progressive impulse has a paternalist dimension that liberals have historically resisted. One analysis notes that liberals promoted an idea of what a desirable character would look like and set preconditions for full participation in democratic life, excluding first the propertyless and then those without minimal educational standards, and excluding women until 1928 in the UK . American progressivism was not exempt from paternalist traits, with Walter Lippmann extolling the importance of experts in relation to the general public in his book Public Opinion . Liberalism contains resources for criticizing this paternalism, because its core commitment is to justifying power to those subject to it, not to governing them for their own good.
The myth that liberalism is progressivism matters because it allows critics to attack liberalism for sins that belong to a different tradition. When progressives used state power to impose their vision of the good society, they were not acting on liberal principles; they were acting on a confidence in expertise and administration that liberalism's own commitment to individual judgment should have restrained. Recovering the distinction allows liberals to acknowledge the tradition's failures without conceding that those failures were inherent to liberalism itself.
Why the Myths Persist
The Rhetorical Utility
The myths persist because they are useful. Calling an opponent a socialist is a way of associating them with totalitarianism and economic failure. Calling them a progressive is a way of associating them with elite paternalism. Calling them a liberal, in some contexts, is a way of associating them with weakness and indifference to the working class. The terms are not neutral descriptors but weapons in a contest over legitimacy. This is why analytical precision matters: without it, political debate becomes a contest of labels rather than a discussion of principles and consequences.
The myths also persist because the historical record is genuinely complex. Liberalism has changed over time, and the changes have been significant enough that different eras of the tradition can look like different ideologies. The classical liberalism of the nineteenth century is not the social liberalism of the twentieth, and neither is identical to the neoliberalism of the late twentieth and twenty-first centuries. This complexity is not a reason to abandon the concept of liberalism, but it is a reason to be precise about which liberalism one is discussing and which historical moment one is invoking.
The Corrective
The corrective to the myths is not a single definition but a disciplined attention to context. When someone says liberal, ask: which liberal, in which country, in which era? When someone says socialism, ask: do they mean public ownership of the means of production, or do they mean welfare state redistribution? When someone says progressive, ask: do they mean a commitment to social reform, or do they mean a confidence in administrative expertise? These questions do not resolve the political disagreements, but they clarify what is actually being disagreed about.
The myths about liberalism are not merely errors to be corrected; they are symptoms of a political vocabulary that has become disconnected from the history it claims to describe. Reconnecting the vocabulary to the history is the first step toward a more honest debate. The liberal tradition contains genuine tensions and genuine achievements, and neither can be understood if the word is allowed to mean whatever the speaker wants it to mean.
The myths about liberalism ultimately reveal more about the mythmakers than about liberalism itself. Those who insist that liberalism is socialism are usually defending a particular set of economic arrangements against criticism. Those who insist that liberals are left-wing are usually trying to discredit a political opponent. Those who conflate liberalism with progressivism are usually trying to attribute the failures of administrative governance to the liberal tradition as a whole. The myths are not innocent mistakes; they are moves in a political argument. The best response is not to defend liberalism against every charge but to insist on precision—to ask what the critic actually means, and whether the historical record supports the claim.
