One way to think about these themes is to associate Clifford and his impotence with the war, psychological and sexual alienation, and the rapid industrialization that is polluting the English countryside. Mellors, on the other hand, is connected to physical labor and the natural world and, of course, sexual potency. Lawrence is pretty explicit about this duality. Connie, of course, is associated with restoration; in a sense, through her sexual gratification she is "restored" to womanhood and, in a larger sense, points a way toward a larger restoration of English society. While it would be simplistic to say that Lawrence is arguing that sex is the answer to the social rottenness that followed World War I in England, it's also clear that the immediacy and spontaneity of Mellors' and Connie's relationship is meant to be a kind of antidote to Clifford's depression and the class distinctions that circumscribed British society at the time.
