Many of the most contentious debates right now center on whether we, as individuals — and as a country — are willing to revise. To revise our understanding of history. To revise the kind of language we use. To revise the nature of our personal, and national, identities. To revise how we act in our everyday relationships. Revision like this is often necessary, but that doesn’t mean it’s easy. Making fundamental changes to the way we think, speak and act requires the kind of self-scrutiny, discomfort and sacrifice that many of us would rather avoid. There are few public figures who model revision — of one’s work and one’s life — as openly and honestly as Kiese Laymon. Laymon has written the prizewinning memoir “Heavy” as well as essays for The New York Times, ESPN and the Oxford American. His nonfiction tackles sports, popular culture, the politics of literary publishing and, above all, his home state of Mississippi. On every page, you’ll find wit, but also heart-stopping vulnerability and a reckoning with tough love: for himself, his kin, his community and the complicated places where he has spent his life. Laymon has mastered the art of revising his own words. But for him, revision is also a moral, even a spiritual, act — a crucial part of becoming a loving and responsible human being. He is the first to admit that he is a work in progress, that each period of his life is a draft that can be improved. In a way, Laymon thinks of his entire life as an act of revision. And he nurtures a radical hope that America can change for the better, too. This conversation focuses on how Laymon thinks about revision. But it also considers how he navigates a publishing world that often puts pressure on minority-group artists to suppress their full identities to appeal to white audiences, the way his writing pushes the boundaries of conventional genre and canon, why Americans have such a hard time reassessing ourselves and what we can gain from trying to change.
