When a politician dismisses a policy proposal as unrealistic, something powerful is happening beneath the surface. They aren't simply making a factual claim about what's possible. They're drawing a boundary around political imagination itself—deciding, on behalf of everyone, which futures are worth discussing and which should be quietly shelved.

Political pragmatism presents itself as the opposite of ideology. It claims to deal with what works rather than what we wish for. It positions itself as the adult in the room, the voice of reason against dreamers and radicals. But this self-presentation conceals a profound political choice: the choice to treat current arrangements as the baseline from which all realistic proposals must depart.

What if pragmatism—at least in its dominant political form—is not the absence of ideology but one of the most effective ideological tools available? What if the appeal to being realistic is itself a deeply conservative move, one that protects existing power by making alternatives literally unthinkable? That's the question worth sitting with.

Every political debate operates within a window of acceptable positions. Overton's famous insight was that this window isn't fixed—it shifts over time. But the mechanism that holds the window in place at any given moment is less discussed. Pragmatism is one of the most powerful of those mechanisms. By sorting proposals into 'realistic' and 'unrealistic' before they're even debated on their merits, pragmatism functions as a gatekeeper to political imagination.

Consider how universal healthcare was dismissed as impractical in mainstream American politics for decades, while being completely ordinary in dozens of other countries. The claim wasn't that it was morally wrong—it was that it simply couldn't be done here. That framing foreclosed debate by converting a political question into a technical one. The issue stopped being should we and became we can't, which requires no further argument.

This narrowing effect is not neutral. When you shrink the range of debatable options, you systematically favor whoever benefits from current arrangements. If the only permissible changes are incremental tweaks to the existing system, then the existing system's core logic—its distribution of wealth, its power hierarchies, its assumptions about who matters—remains unchallenged. Pragmatism doesn't just exclude certain policies; it excludes certain questions.

The philosopher Herbert Marcuse called this one-dimensional thinking: a mode of political reasoning that can only conceive of more or less of what already exists, never something fundamentally different. When pragmatism becomes the dominant political language, radical alternatives don't get refuted. They get something worse—they get ignored as self-evidently absurd. And that invisibility is where the conservatism hides.

Takeaway

When someone calls your idea unrealistic, ask what they're treating as fixed. The boundaries of 'the possible' are always political choices disguised as facts about the world.

If pragmatism is about dealing with reality, then everything hinges on who gets to define what reality is. And this is where the power analysis becomes unavoidable. The authority to declare something realistic or unrealistic is not distributed equally. It concentrates in think tanks, editorial boards, credentialed experts, and political insiders—people who, by and large, are already well-served by existing institutions.

This isn't a conspiracy. It's something more durable: a shared common sense among elites about what the world allows. When a Wall Street economist says a financial transaction tax is impractical, they're not lying—they're reasoning from within a framework where capital mobility is a fixed constraint rather than a political choice. Their expertise is real, but it comes embedded in assumptions that protect the structures from which their expertise derives its authority.

Foucault's concept of power-knowledge is instructive here. The ability to produce authoritative knowledge about what's possible is itself a form of power. Those who control the models, the data, the forecasting frameworks—they don't just describe reality. They shape it by determining which futures get taken seriously. A proposal that gets scored by the Congressional Budget Office enters political reality. One that doesn't remains a fantasy, regardless of its actual merits.

Notice, too, whose lived experience counts as evidence. When working-class communities describe what they need, it's treated as anecdote. When economists model those same needs through institutional frameworks, it becomes data. The filter of pragmatism systematically privileges abstract, technocratic knowledge over embodied, experiential knowledge—and this isn't a bug. It's a feature that keeps the definition of the possible firmly in the hands of those who benefit from its current boundaries.

Takeaway

The power to define what counts as realistic is one of the most consequential and least visible forms of political power. Whoever sets the boundaries of the possible controls the outcome before the debate even begins.

Critiquing pragmatism doesn't mean embracing wishful thinking. The point isn't that constraints don't exist—it's that we should interrogate which constraints we accept and why. There's a difference between genuine material limits and limits that are political choices wrapped in the language of necessity. Gravity is a constraint. The structure of the tax code is not. Treating both with the same inevitability is an ideological move.

The sociologist Erik Olin Wright proposed what he called real utopias: concrete experiments that demonstrate the viability of alternatives within existing conditions. Worker cooperatives, participatory budgeting, community land trusts—these aren't fantasies. They exist, they function, and they embody logics that differ fundamentally from dominant arrangements. They expand the definition of the possible not through argument alone but through demonstration.

This is where critical theory meets practice. Expanding political imagination requires building what Gramsci called counter-hegemony: alternative frameworks of common sense that make different futures feel as natural and inevitable as the current one does now. Every successful social movement has done this. Abolitionists made the end of slavery thinkable before it was achievable. Suffragists made women's political participation imaginable before it was law.

The task isn't to reject all pragmatic reasoning but to politicize it—to insist that every appeal to realism declare its assumptions openly. What are you holding constant? Why? Who benefits from that particular definition of the fixed and the flexible? When these questions become habitual, pragmatism loses its power to silently foreclose alternatives. It becomes what it should have been all along: one voice in the debate, not the referee.

Takeaway

Genuine political imagination isn't naive optimism—it's the disciplined refusal to treat political choices as natural laws. Every constraint deserves the question: who decided this was immovable, and what would change if it moved?

The next time someone tells you to be realistic, pause. Ask yourself what's being smuggled in under the authority of that word. Pragmatism at its best is a commitment to results. But at its worst—and most commonly—it functions as a mechanism for protecting the present from the future.

The boundaries of political possibility are not discovered like natural laws. They are constructed, maintained, and enforced—often by those who benefit most from where the lines currently sit. Recognizing this doesn't make you impractical. It makes you honest about how power works.

Real political thinking starts not with accepting the given but with asking who gave it, and what it would take to give something different.
