Frank Lentricchia 
Criticism and Social Change [PDF ebook] 

"Criticism and Social Change speaks with special timeliness to the role of the political intellectual (here embodied in Kenneth Burke). Lentricchia’s provocative analysis demands serious reflection by American radicals."-Frederic Jameson"A profound meditation on relations obtaining among writing, political consciousness, and criticism this last taken in its most general sense. It is written with passion and grace; it is shot through with learning, intimate knowledge of the critical tradition, and a deep (though by no means uncritical) understanding of the work (as well as social significance) of Kenneth Burke." Hayden White
