In 1888, speaking about the possibility of Mormon literature, the church leader Orson F. Whitney made an audacious promise to his fellow Mormons: “We will yet have Miltons and Shakespeares of our own.” Yet 125 years later, there is no Mormon Milton. There is no Mormon Milosz, no Mormon Munro.

Mormons are, on average, better educated than most Americans, and they have written popular fiction. But Mormon authors tend to cluster in genre fiction, like fantasy, science fiction, and children’s and young adult literature. Orson Scott Card, who wrote “Ender’s Game,” the sci-fi novel on which the country’s current top-grossing movie is based, is a member of the Church of Jesus Christ of Latter-day Saints. So is Stephenie Meyer, author of the “Twilight” series.

In the United States, Jews, blacks and South Asians, while they have produced no Milton or Shakespeare — who has, lately? — have all had literary renaissances. Mormons are more likely to produce work that gets shelved in niche sections of the bookstore. And as it turns out, Mormon authors themselves wonder if their culture militates against more highbrow writing. They have a range of possible explanations.

“It is a fair thing to point out,” said Shannon Hale, a Mormon who writes young adult fiction, “that there have been very prominent Jewish writers that have received a lot of accolades, and worldwide the number of Mormons are comparable to the number of Jews, so why hasn’t that happened?”
