Here's a breakdown:
* Internal Struggle: Henry grapples with the ethical implications of his work as a neurosurgeon. He questions the value and morality of his actions, especially when he operates on patients who are no longer conscious. This internal conflict is further fueled by his encounter with the Baxters, a family facing a medical crisis, which forces him to confront the human cost of his profession.
* Family Dynamics: Henry's relationship with his wife, his daughter, and his son is strained. He feels disconnected from them due to his work and his growing sense of alienation. The Baxter family's chaotic and emotional dynamic highlights the contrast between Henry's own family life and the warmth and love he observes in the Baxters.
* Social Commentary: McEwan uses Henry's experiences to explore larger themes of social class, privilege, and the disconnect between different social groups in Britain. Henry's privileged lifestyle and his encounter with the Baxters, a lower-middle-class family, expose the social inequalities that exist within society.
Ultimately, "A View from Saturday" is not driven by a single, external conflict. Instead, it explores the internal struggles of a man grappling with the complexities of modern life, his profession, and his relationships. The novel uses these struggles to create a multifaceted exploration of human nature and the challenges of finding meaning and connection in a complex and changing world.
