J.B. Priestley's 'An Inspector Calls' presents a chilling indictment of pre-war British society through the lens of the Birling family. Central to this critique are the contrasting figures of Mrs. Birling and her daughter, Sheila. While both women are products of their privileged environment, their responses to the Inspector's revelations and their capacity for genuine change diverge dramatically. Mrs. Birling, a pillar of social convention and self-importance, remains stubbornly entrenched in her class prejudices and denial, ultimately serving as a symbol of the old guard's moral bankruptcy. Sheila, conversely, undergoes a profound and painful transformation, moving from a shallow, self-absorbed debutante to a woman acutely aware of her responsibility and the suffering of others. This essay will argue that the stark contrast between Mrs. Birling and Sheila highlights Priestley's central theme: the possibility of moral awakening and the tragic consequences of willful ignorance.
Mrs. Birling embodies the entrenched social hierarchy and moral complacency of the Edwardian upper class. As the wife of Arthur Birling, a man ambitious for social advancement, she prioritizes respectability and appearances above all else. Her pronouncements are often laced with a condescending superiority, particularly when discussing those of lower social standing. When Eva Smith (under the name Daisy Renton) appeals to her for help from the Brumley Women's Charity Organisation, Mrs. Birling dismisses the girl with unbending severity, seeing only a wilful young woman seeking to exploit the system. Her rigid adherence to social etiquette and her belief in her own inherent rightness prevent any genuine empathy. She insists, "I did nothing I'm ashamed of. And I can't think of a single person I can blame, except the young man who was the father." This statement, delivered with unwavering conviction, reveals her complete inability to accept responsibility or to see beyond her own narrow worldview. She is a woman defined by her social position, her judgment shaped by class and convention, rather than by any innate sense of compassion or justice. Her resistance to the Inspector's questioning and her eventual attempt to discredit him underscore her deep-seated need to maintain the façade of respectability, even at the expense of truth and human decency.
Sheila, on the other hand, begins the play as a superficially happy, somewhat spoilt young woman, deeply concerned with her recent engagement to Gerald Croft. Her initial reaction to the Inspector's inquiry is one of mild curiosity, even amusement, at the disruption to her family's comfortable evening. However, as the Inspector systematically unveils her role in Eva Smith's downfall – her jealousy over Gerald's affair with Eva and her subsequent petty act of malice in ensuring Eva was sacked from Milwards – Sheila's composure shatters. This revelation is the catalyst for her awakening. Unlike her mother, Sheila possesses a nascent capacity for introspection and a sensitivity that allows the Inspector's words to penetrate her privileged shell. Her distress is palpable; she cries out, "Oh—how horrible! Was it an accident?" This immediate emotional response, though fuelled by guilt, marks the beginning of her moral development. She begins to understand the interconnectedness of their actions and the devastating impact they can have on vulnerable individuals. Her growing horror and self-recrimination, "But I'm sure I'm sorry. It was the only time—and just because I'm younger." reveal a dawning awareness of her own culpability and the hypocrisy of her family's behaviour.
The contrast between mother and daughter becomes most pronounced in their final reactions. Mrs. Birling, confronted with irrefutable evidence of her cruelty and the fatal consequences, retreats further into denial and indignant self-preservation. Her final pronouncements, particularly her insistence that "the Inspector was a fraud" and that "the whole thing is simply a gag," demonstrate her unshakeable commitment to maintaining the status quo and avoiding any personal accountability. She represents a static moral position, incapable of growth or genuine remorse. Sheila, however, is irrevocably changed. She rejects her family's attempt to dismiss the Inspector and his message. Her final lines, "And I tell you, then that the Inspector was right. . . . He was right. It was, and that's the hellish thing." signify a profound shift. She has shed her former self and embraced a new understanding of responsibility and the shared humanity that binds them all. Her willingness to accept the Inspector's lesson, even knowing the devastating consequences for her family's reputation, marks her as a figure of hope, albeit a sorrowful one, in Priestley's bleak social commentary.
In conclusion, the parallel yet divergent paths of Mrs. Birling and Sheila serve as the dramatic engine for Priestley's moral argument in 'An Inspector Calls.' Mrs. Birling's unyielding adherence to social convention and her complete lack of empathy render her a tragic figure of moral failure, a representation of a society too proud and too blind to change. Sheila's painful journey from youthful ignorance to mature awareness, however, offers a glimmer of hope. Her transformation underscores Priestley's belief that individuals, even those born into privilege, can and must confront their own prejudices and accept their collective responsibility for the well-being of society. The stark contrast between their fates provides a powerful and enduring message about the necessity of moral awakening in the face of social injustice.
