That’s a profound and difficult question—one that gets at the very heart of how we imagine the conditions under which human beings can think and act together. Rather than offering a firm yes or no, I think it’s helpful to pause with the question and dwell in its implications.

Let’s start with the idea of the lifeworld. In Habermas’s sense, this refers to the implicit background of shared meanings, cultural understandings, and normative expectations that make communication possible at all. In that context, communicative reason arises from within the lifeworld—it is immanent, not imposed. The lifeworld is what we carry with us, sedimented in language, gestures, habits, and expectations. Reflection and judgment here emerge in everyday interactions, as we contest or reaffirm these background norms. Collective decision-making, then, is not something added on top of the lifeworld but a form of its own reflexivity—it becomes a way the lifeworld renews or transforms itself.

But Arendt’s vision complicates this picture. For her, the polis is not just a continuation of the lifeworld—it is something qualitatively different. It’s the space in which people appear to one another not as bearers of background norms, but as distinctive selves, speaking and acting in ways that reveal who they are. Judgment, in Arendt’s thought, is not merely about norm-following or background contestation; it’s an aesthetic-political act of evaluating what is worthy to be remembered, shared, and preserved. The polis is where the fragile miracle of plurality becomes visible—not just consensus but dissonance and appearing together. It’s a space of risk, spontaneity, and exposure, and in that way, it may actually precede or stand apart from the lifeworld.

So: if we say that communicative reason originates in the lifeworld, we’re emphasizing the ongoing, habituated, culturally embedded nature of human reasoning. If we say that it belongs to the polis, we’re emphasizing exposure, appearance, judgment, and the performative dimension of thinking and speaking together. Both have force. The lifeworld gives depth, continuity, and shared intelligibility. The polis gives visibility, differentiation, and public significance.

Rather than choosing, I’m tempted to say that judgment, reflection, and collective decision-making require a kind of double anchoring: they emerge from the depths of the lifeworld, but they take on form and consequence in the polis. The lifeworld gives content and continuity to our reasoning, while the polis gives it a stage, an audience, and a kind of truth-test—how will this hold up before others?

That said, there’s still a danger in this synthesis. It risks smoothing over the real tension: in times of rupture or crisis, the lifeworld may be exhausted, or the polis may be absent or colonized. In those moments, neither offers a stable ground—and then judgment must arise, terrifyingly, from nothing but the courage to speak anyway.
