Last year I gave the Israeli artist Amir Nave an old Hebrew copy of Immanuel Kant’s Perpetual Peace, which I teach every so often in my Introduction to Political Theory class. He took the book, flipped through it, ripped out the title page, turned it upside down, signed it and returned it to me. Nave, an Arab Jew of Iraqi descent, didn't say anything, but the gesture was eloquent enough: we are living in an era of perpetual war, and peace emerges, if at all, in the interregnum. Nave’s children go to the same school as mine. It’s called Hagar, after the biblical figure who wandered between different peoples and cultures in the desert not far from where I live. Hagar was founded by a group of Jewish and Palestinian parents who wanted to create a shared space for their children. It’s the only non-segregated school in the Negev region, which is home to about 700,000 Israelis, more than a quarter of whom are Palestinian Bedouin.
