Philosopher Steve Fuller has long asked who decides what counts as true — and now he offers an answer that unsettles the very ground beneath our public conversations. Writing in a moment of deep social fracture, Fuller argues that contemporary polarization is not a matter of differing angles on a shared reality, but of people inhabiting entirely separate epistemological worlds, each with its own logic of evidence, authority, and truth. If he is right, the ancient hope that reason and dialogue can reunite us rests on a premise that may no longer hold.
We inhabit different realities, not just perspectives, says philosopher Steve Fuller
We're inhabiting different worlds, not just seeing them differently
So Fuller is saying we're not just disagreeing about facts. We're disagreeing about what facts are?
Exactly. He's drawing a line between perspective and reality. A perspective is something you can shift. But if you're operating from a different epistemological framework—different assumptions about evidence, authority, truth itself—then you're not just seeing things differently. You're inhabiting a different world.
But how do we actually know that's what's happening? The source material here is pretty thin. We have Fuller's claim, but do we have evidence that people are actually operating from incompatible frameworks, or is this a philosophical argument that sounds true?
That's fair. The source doesn't give us case studies or empirical backing. It's a conceptual argument. But the observation is real—people do seem to be talking past each other in ways that go beyond disagreement.
If that's true, what does it mean for how we solve polarization? Can you even solve it?
That's the unsettling part. If people inhabit different realities, then the standard approach—better communication, more facts, civil dialogue—might be built on a false assumption. You can't bridge realities by sharing perspectives.
But we should be careful here. Fuller might be describing something real about how people experience disagreement without that meaning they literally inhabit different realities. There's a difference between "people operate from different epistemological frameworks" and "there are multiple incompatible realities." The source doesn't really distinguish between those.
True. And the practical question remains: even if we accept Fuller's framing, what do we actually do differently? The source doesn't answer that.
So it's a diagnosis without a prescription.
It's a diagnosis that might change how we think about the prescription. Instead of trying to get people to see the same facts, maybe we need to understand how their different realities came to be.
Which is harder and slower and doesn't give us the quick fix we want. But yes, that's probably more honest about what we're actually dealing with.
Il Polso
- The familiar tools of reconciliation — fact-checking, civil dialogue, shared information — are built on the assumption that a common reality exists beneath our disagreements, and Fuller's argument pulls that foundation away.
- When two people cannot agree on what counts as evidence or who has the right to speak truth, their conflict is no longer a misunderstanding to be cleared up but a collision between incompatible worlds.
- Institutions from schools to newsrooms are already living this crisis, watching information campaigns fail to move people who are not simply misinformed but operating from different epistemological ground entirely.
- The path forward, if one exists, demands something harder than empathy or better listening — it requires excavating the foundations beneath each reality and asking whether any shared bedrock lies beneath them at all.
Philosopher Steve Fuller has long asked who decides what counts as true — and now he offers an answer that unsettles the very ground beneath our public conversations. Writing in a moment of deep social fracture, Fuller argues that contemporary polarization is not a matter of differing angles on a shared reality, but of people inhabiting entirely separate epistemological worlds, each with its own logic of evidence, authority, and truth. If he is right, the ancient hope that reason and dialogue can reunite us rests on a premise that may no longer hold.
Steve Fuller has spent his career studying how knowledge is made and who holds the power to define truth. His latest argument goes further than the familiar diagnosis of filter bubbles and echo chambers. The problem, he contends, is not that people see the same world from different angles — it is that they are living in different worlds altogether.
The distinction carries real weight. When we speak of differing perspectives, we still assume a shared reality underneath: the same facts, the same events, the same basic terrain. A perspective can be revised. You can see the other person's point. But Fuller is describing something more fundamental — a divide in the very frameworks people use to determine what a fact is, what evidence means, and where truth comes from. These are not perspectives. They are separate realities.
The consequences for how we think about polarization are immediate and sobering. Most efforts to bridge division — dialogue initiatives, fact-checking projects, calls for civility — rest on the premise that better communication can restore common ground. Fuller's argument suggests those efforts are built on a false foundation. You cannot share your way across a gap between two realities.
This does not make reconciliation impossible, but it makes it harder and stranger than we have imagined. The work is no longer about helping people see the same facts differently. It is about understanding how separate realities form, what holds them together, and whether anything lies beneath the frameworks themselves. That requires a deeper humility — not just the willingness to hear another view, but the willingness to question the very ground you are standing on.
Fuller's argument arrives precisely when institutions most need it. The failure of information to persuade, the sense that neighbors are living in different worlds — these are not symptoms of bad faith or poor communication alone. They may be evidence that the epistemological divide is exactly as deep as it feels.
Philosopher Steve Fuller has spent decades studying how knowledge gets made and who gets to decide what counts as true. His latest argument cuts deeper than the familiar complaint that we're living in separate bubbles. It's not that we see the world differently, he contends. It's that we're inhabiting fundamentally different worlds altogether.
The distinction matters more than it might first appear. When we say two people have different perspectives, we're still assuming they're looking at the same thing from different angles—that there's a shared reality underneath, and better communication or more facts might bridge the gap. A perspective is something you can change your mind about. You can see the other person's point. You can find common ground.
But Fuller is arguing for something more unsettling. He's suggesting that the epistemological divide in contemporary discourse runs so deep that people aren't disagreeing about facts within a shared framework. They're operating from entirely separate frameworks about what counts as a fact in the first place, what evidence means, where truth comes from, and who has the authority to speak it. These aren't perspectives. They're different realities.
This reframing has immediate consequences for how we think about polarization and the possibility of reconciliation. The standard approach to political or cultural disagreement assumes that if we could just communicate better, share more information, or listen more carefully, we could find our way back to common ground. It's the premise behind most dialogue initiatives, fact-checking projects, and calls for civil discourse. But if Fuller is right, those efforts rest on a false foundation. You can't bridge a gap between two realities by sharing perspectives. The gap isn't about how you see things. It's about what you think is real.
The implication is both sobering and clarifying. It suggests that the polarization we're experiencing isn't primarily a failure of communication or a shortage of empathy. It's a fundamental incompatibility in the frameworks people use to make sense of the world. Two people might look at the same event, the same data, the same claim, and because they're drawing on different epistemological foundations—different assumptions about evidence, authority, causation, and truth—they arrive at conclusions that feel not just wrong to each other, but unintelligible.
This doesn't mean reconciliation is impossible. But it does mean that reconciliation can't work the way we've been trying to make it work. If people truly inhabit different realities, then the work isn't about getting them to see the same facts differently. It's about understanding how those different realities came to be, what holds them together, and whether there's any common ground beneath the frameworks themselves. It's harder work, and it requires a different kind of humility—not just the willingness to listen to another perspective, but the willingness to recognize that your entire sense of what's real might be built on foundations that someone else has never stood on.
Fuller's argument arrives at a moment when many institutions are struggling with exactly this problem. Schools, newsrooms, governments, and families are all grappling with the fact that sharing information doesn't seem to work anymore. People don't just disagree. They seem to be living in different worlds. Understanding why—understanding that they might actually be doing exactly that—could reshape how we approach the divisions that define our time.
