Pieter De Buysser and Jacob Wren wrote a letter that began, “An Anthology of Optimism is a pre-emptive celebration of a critical optimism we tentatively hope will increase in the twenty-first century.” They sent the letter to writers, artists, thinkers, scientists, politicians and businesspeople all over the world, asking for a response, a contribution. This could be anything: a photograph, a piece of music, an object, a short text, a drawing or painting, a film or video, or something else entirely.
