I Do Know Some Things is a brave book, both in content and method.It is brave to write about childhood scars and the heartbreak the dead leave behind. It is brave to reconfigure one’s life in the aftermath of a stroke. Richard Siken presents these subjects directly, without ornament, and with nothing to hide behind, confronting the fact that he can no longer manipulate the constructions of form, or speak lies that tell the truth. In spite of these limitations, Siken chooses to write these poems and release them into a dangerous world. Each image, each sentence, is as direct as the American artist Jasper Johns’s shooting targets. Each poem is like a small room in a house, a room where you will be punched in the throat. As he claws himself back into a self, into a body, Siken has written a book that is unsettling and autobiographical by necessity, and its seventy-seven prose poems invite the reader to risk a difficult intimacy in search of yet deeper truths.
