Like Swift and Twain, Roth is aesthetically propelled by anger; it supplies the energy needed for the massive, self-imposed task of dissecting, novel after novel, the suffocating paradoxes of twentieth-century America. Like Lenny Bruce, Roth in his early work used rant as a way of exercising his vitality and crafting an obscenity-fuelled response to a bland, hypocritical national environment. As he’s matured, however, his anger has grown more complex, manipulated as carefully as the shifting voices and points of view that help make his prolific body of fiction both deeply tragic and rich in comic expression.
