Duttman's methodology is as groundbreaking as his discoveries. Alan Udoff writes: "This is not an exposition in the conventional sense: a scholarly, historical report, with some attempt at criticism. Rather, it is at every turn a thinking through of certain texts, a thinking that, in putting questions to the texts ... reveals or releases what is ... stored in those texts". Duttman's questions are so philosophically and theologically penetrating that the reader is set out in new direction of thinking.
While Duttman's book helps the reader achieve a new understanding of the gift of language in the works of Adorno, Benjamin, Heidegger, and Rosenzweig, his study also is fraught with implications for reading Derrida, Deleuze, Levinas and Lyotard.
