"Since 1962, when the darkest thoughts of Mark Twain about the universe and God emerged from the publication of his Letters from the Earth, revealing that he was more than just a funnyman, scholars have labored to plumb his religious, or anti-religious, views. Dwayne Eutsey has clarified much of this issue soundly and eloquently in “There is No Humor in Heaven.” He puts Twain wholly in the context of his era, when American Christianity was regularly in the news and on the debate stage, playing the same role that politics and celebrity-worship do in our time. Before Eutsey, no one has explicated so clearly the author’s relation to what were then regarded as revolutionary movements such as Unitarianism; the “liberal religion” of his closest friend, a New England minister; and even – and here Eutsey really breaks ground – the influence of Hinduism, by way of the religious radical Moncure Conway and the Hindu reformer Protap Mazoomdar, on his later, darker works, in which Eutsey finds unexpected faith and optimism." —Steve Courtney, author of Joseph Hopkins Twichell: The Life and Times of Mark Twain's Closest Friend
