It was late February when Suhaila Hashimi slid into one of the last available seats in the front row of her philosophy class, “The Place of Persons,” an intro-level course at Brown University about the moral and metaphysical status of personhood. Even though she was 23, and this was a class mostly for students who were several years younger, Hashimi fit in with them, her dark brown hair pulled into a messy ponytail, eyeliner darkening her lower lids, an oversize hoodie with Brown’s emblem on the front, black jeans tucked into black combat boots.
