A man's head is his castle

A man's head is his castle

In the context of Joseph Heller's work, particularly his most famous novel "Catch-22," the phrase "A man's head is his castle" takes on a deeper meaning. Heller's satirical and darkly comedic portrayal of war and bureaucracy in the novel highlights the absurdity and chaos of the human condition. In this context, the idea of a man's head being his castle can be seen as a metaphor for the individual's inner world and the struggle to maintain a sense of autonomy and control in the face of external forces.
