Dark times as a darkened public realm
For Arendt, times are 'dark' not simply because of atrocity, but because the public realm stops giving light. That light comes from the space where people's words and deeds can be seen and judged by others. When official speech turns into 'mere talk' that sweeps unpleasant facts under the carpet with moral exhortations and plausible-sounding explanations, people lose the shared space where reality can be seen.
