Rodney Evans is still making movies, despite having lost much of his vision. His new documentary, 'Vision Portraits,' is about how he and three other blind or visually impaired artists (a photographer, a dancer, and a writer) continue to do their work. Linguist Geoff Nunberg considers the use of the word "they" as a gender-neutral pronoun. 'New Yorker' staff writer Jia Tolentino writes about how social media shapes identity, public discourse and political engagement, particularly for millennials like herself. She talks about growing up in a Houston megachurch, her devastating year in the Peace Corps, and how religion led her to MDMA. Her new book of essays is 'Trick Mirror.'
