Because New Criticism isolated the text and excluded historical and biographical contexts, critics argued as early as 1942 that Brooks' approach to criticism was flawed for being overly narrow and for "disabl any and all attempts to relate literary study to political, social, and cultural issues and debates" (1350). His reputation suffered in the 1970s and 1980s when criticism of New Criticism increased. Brooks rebuffed the accusations that New Criticism has an "antihistorical thrust" (Leitch 2001) and a "neglect of context" (Leitch 2001). He insisted he was not excluding context because a poem possesses organic unity, and it is possible to derive a historical and biographical context from the language the poet uses (Singh 1991). He argues "A poem by Donne or Marvell does not depend for its success on outside knowledge that we bring to it; it is richly ambiguous yet harmoniously orchestrated, coherent in its own special aesthetic terms" (Leitch 2001).
