The essence of our identity is a central theme in Joseph Conrad's "The Secret Agent." The quote "We can never cease to be ourselves" underscores the enduring nature of personal identity, suggesting that regardless of circumstances or external pressures, our true selves remain intact. This idea reflects the complexity of human nature, where internal truths inevitably shape actions and choices.

Conrad's exploration of this concept invites readers to consider how identity influences behavior and moral choices. Characters in the narrative face conflicts that challenge their authenticity, yet their core selves ultimately guide their destinies. The quote serves as a reminder that self-awareness is integral to navigating life's complexities while staying true to one’s nature.
