Friends’ attitudes to literary works have altered substantially from the inception of the movement to the present day. While early Friends believed that writing should be simple and honest -- and, consequently, that artful genres were at best frivolous and at worst diabolical -- many Quakers today believe that God is immanent in all forms of human expression. Recent Quaker writers have written novels, ghost stories, murder mysteries, science fiction and experimental poetry, all literary forms that earlier Friends would have denounced as profane or vain.
