The problem of Arendt
That she refers to "plurality" out of a sympathy for an idea. Readers never escape the sense she's making arguments explicitly from preference. And she argues for things she thinks are being lost. The same with Habermas and the rest. But nothing's been lost: facts that were once seen as foundational are now ignored. Plurality like partiality is not an option; it's a given. We experience a Rashomon world whether we want to or not. And the fact of our collective efforts is no less a fact for the contemporary preference for the descriptive terms of individualism.
