All This Thinking explores the deep friendship and the critical and creative thinking between Bernadette Mayer and Clark Coolidge, focusing on an intense three-year period in their three decades of correspondence. These fiercely independent American avant-garde poets have influenced and shaped poets and poetic movements by looking for radical poetics in the everyday. This collection of letters provides insight into the poetic scenes that followed World War II while showcasing the artistic practices of Mayer and Coolidge themselves. A fascinating look at both the poets and the world surrounding them, All This Thinking will appeal to all readers interested in post–World War II poetry.
