This episode features In praise of darkness, a waning reserve by Sigri Sandberg, published in AR April 2020. We chose to revisit this piece, which we published as the keynote for the Darkness issue nearly 18 months ago, as this week we mark the launch of our Light issue. With the Darkness issue we explored how darkness is a critical resource that is increasingly endangered, where shadows can be sites of subversion in a culture of ever-increasing surveillance. With our September 2021 issue, we flip the switch to consider access to light as a right that is unevenly distributed, continuing political questions of visibility and invisibility, and exploring connections between light and safety, between energy and technology.
