David Grossman has known war all of his life. The Israeli writer, born and raised in Jerusalem, has long mined themes of grief and conflict in his novels and non-fiction. His latest book, The Thinking Heart, collects essays and speeches from the years leading up to and following the Oct. 7, 2023 Hamas attack on Israel. Grossman joins Piya Chattopadhyay to reflect on the aftershocks of that day, and what it will take to achieve lasting peace between Palestinians and Israelis.
