These letters show the development of Burke's thought in the last thirty or so years of his life, when he remained remarkably productive not only as a correspondent but as a critic and traveling scholar. Rueckert became for Burke both student and "co-conspirator," with Burke himself playing the roles of teacher, mentor, father, and peer. While Burke corresponded for many years with Malcolm Cowley, William Carlos Williams, Hugh Duncan, and others, with Rueckert, we see him writing to someone who may have understood and appreciated his work more than anyone.
