The paper seeks to throw light on E. L. Doctorow’s vision of history through the postmodern perspective. Postmodernism is a de-essentialising and de-naturalising critique of all the meta-narratives which claim to ground knowledge, ethics, meaning and truth within some monolithic pattern. It uses such staples of the older humanist tradition and undermines them from within. The paper will highlight how Doctorow uses postmodernism to reveal the illusory nature of our claims to know truth from the outside. For this purpose, it will analyze his novel – the Book of Daniel – and focus on his use of some postmodern features like irony, parody, ambiguity, self-reflexivity, metafiction and uncertainty. It will also dwell on the double-coded nature of his perception of postmodernism, thereby revealing its liberating potential as well as political quietism.
