The main purpose of this paper is to analyze the modernist characteristics during the period of Doris Lessing - one of the most charming fiction writers of modern English literature. To work out the modernist trends in Doris Lessing’s works is altogether a difficult task as the modern and post-modern features of her works are indistinguishably intermixed with each other. Even the great critics over the last fifty years have failed to reach to an all acceptable conclusion in this regard. Their decisions and conclusions are varied and different and often, seem to be contradictory. At the very start, a reader gets worried to find a plethora of definition of the term “modernism”. And then there are as many definitions of the term as there are critics. Some call modernism a philosophical movement that, along with cultural trends and changes, arose from wide - scale and far - reaching transformations in western society in the late 19^th century and early 20^th century. Nevertheless, modernism was a change greatly felt in the traditional forms of art, architecture, religious beliefs, social organizations and day – to – day activities of life. All of which were deemed to have become ill – fitted in the new economic, social and political environment of an emerging fully industrialized western world.
