The correspondence between Walter Benjamin and Theodor Adorno, which appears here for the first time in its entirety in English translation, must rank among the most significant to have come down to us from that notable age of barbarism, the twentieth century. Benjamin, riddle-like in his personality and given to tactical evasion, and Adorno, full of his own importance, alternately support and compete with each other throughout the correspondence, until its imminent tragic end becomes apparent to both writers. Each had met his match, and happily, in the other.
