Dazzling . . . astonishingly achieved . . . Rahman proves himself a deep and subtle storyteller . . . a novel unashamed by many varieties of knowledge-its characters talk, brilliantly, about mathematics, philosophy, exile and immigration, warfare, Wall Street and financial trading, contemporary geopolitics, Bangladesh, Pakistan, Afghanistan, English and American society, Islamic terrorism, Western paternalism, Oxford and Yale. Isn't this kind of thinking-worldly and personal, abstract and concrete, essayistic and dramatic-exactly what the novel is for? How it justifies itself as a form? Rahman uses his novel to think hard and well, chiefly about connections among class, knowledge, and belonging. In the Light of What We Know is what Salman Rushdie once called an "everything novel." It is wide-armed, hospitable, disputatious, worldly, cerebral. Ideas and provocations abound on every page.
