Themes are ideas that run through a text. In Heroes, the themes of war and heroism; appearances and disguise; loneliness and isolation; and guilt and forgiveness are explored.
In Heroes Robert Cormier introduces four main themes, which can be categorised as follows:
The novel takes place just before, during and immediately after World War Two. It looks at what happens to people as a result of war, and it poses the question: what is a hero?
The novel is very concerned with how people appear to others; it also makes the reader consider whether a disguise has to be literal or can be figurative.
Heroes is concerned with the theme of loneliness. Characters can be very lonely even when they are not alone. They have a sense of isolation because their experiences set them apart from others.
The theme of forgiveness is a major one in Heroes; a sin has been committed but the sinner does not acknowledgeAccept or recognise the truth or significance of something. it. Instead someone else feels the guilt. Characters need to either forgive or be forgiven.
