``It is impossible for me to write about the imagination; it is like asking a fish to describe the sea,`` Mary Ruefle announces at the start of her essay. With wit and intellectual abandon, Ruefle draws inspiration from Wittgenstein, Shakespeare, Jesus, Steve Jobs, Johnny Cash, and Emily Dickson to explore her subject. The chapbook features original interior illustrations.Mary Ruefle is the author of numerous volumes of poetry and prose, including Madness, Rack, and Honey: Collected Lectures, a finalist for the National Book Critics Circle Award in Criticism, and Selected Poems, winner of the William Carlos Williams Award from the Poetry Society of America.
