The founder of Ploughshares, DeWitt Henry recently published Sweet Marjoram, a book of essays following a series of nonfiction books and memoirs, as well as essays. This newest work consists of twenty-two meditations with two-word titles, each prefixed by “on.” One thing we are struck by is the author’s extensive range of knowledge, evidenced at a glance by notably diverse topics: “On Weather,” “On Time,” “On Empathy,” “On Conscience,” “On Falling,” “On Handshakes,” “On Silence,” “On Dignity,” “On Privilege,” On Dreams,” “On Cursing,” “On Voice.” And ten more. An encyclopedic work. This thought-provoking book is nearly exhaustive of human experience, human behavior, psychology—the fundamental nature of humans and their being in the world.
