John Updike’s memoirs consist of six Emersonian essays that together trace the inner shape of the life, up to the age of fifty-five, of a relatively fortunate American male. The author has attempted, his Foreword states, “to treat this life, this massive datum which happens to be mine, as a specimen life, representative in its odd uniqueness of all the oddly unique lives in this world.” In the service of this metaphysical effort, he has been hair-raisingly honest, matchlessly precise, and self-effacingly humorous. He takes the reader beyond self-consciousness, and beyond self-importance, into sheer wonder at the miracle of existence.
